    Full Text Available In the Mahu well block of Junggar basin, the complex formation has many sets of pressure system. Especially, the formation with microcracks in the middle layer is loose and the pressure bearing capacity is low. Lost circulation is prone to occur in this layer. At present, high investment and long drilling period were the main problems in the exploration and development process. The geostress 3D model of Mahu well block was established by means of logging and drilling data. The model provided the three-pressure profiles of Mahu well block for casing program optimization and safety drilling. Each well could be optimized the intermediate casing setting position. The intermediate casing was saved 160 meters long. The total of drilling speed was improved 5 times compared with the past drilling process. Slim hole drilling technology raised ROP 51.96% higher, and the average drilling period is shorten to 24.83 days.

    2004-01-01

    Purpose: To present two unusual cases of well-differentiated thyroid carcinomas Methods:Data gathering thru medical records, diagnostic examinations and laboratory results. Well-differentiated thyroid cancer (WDTC) are among the most common type of all thyroid cancers. These case reports were done because of the fact that both cases showed unusual presentations clinically. The first case had a histopathologic report of papillary cancer of the thyroid with some of the typical features of WDTC but within a month's time from the near-total thyroidectomy procedure, there was progression of the neck enlargement, compression symptoms and eventually stridor. I-131 total body scan showed only a small focus of residual neck tissues in the neck with no distant metastasis. Tracheostomy was done and another debulking of the multiple nodules which showed papillary cancer again this time with some anaplastic cells. The second case is a follicular WDTC who also underwent total thyroidectomy after presenting symptoms of soft tissue metastasis at the left buttocks which turned out to be follicular in origin. After total thyroidectomy, I-131 total body scan showed multiple skeleta/soft tissue metastases. These cases are presented to keep in mind that well-differentiated thyroid cancer may not be all the time slow growing and that it should not be taken for granted in terms of treatment. (authors)

    Full Text Available Much research supports the everyday therapeutic and deeper socialneurophysiological influence of singing songs alone and in groups (Austin, 2008; Cozolino, 2013; Sacks, 2007. This study looks at what happens when Japanese students teach short English affirmation songlet-routines to others out of the classroom (clandestine folk music therapy. I investigate 155 student-conducted musical case studies from 7 semester-long classes (18 to 29 students per class over a 4-year period. The assignments, their in-class training, and their results are introduced, with examples directly from their case studies. Each class published their own booklet of case studies (a class publication, available to readers online for research replication and modeling. Results show that most primary participants enjoyed spreading these positive songlets as they became “well-becoming agents of change” in their own social networks. “Well-becoming” emphasizes an agentive action or activity that creates better well-being in others, an action such as the sharing or teaching of a songlet. The qualitative data reveals a number of types of well-becoming such as social and familial bonding, meaning-making, teaching-rushes, and experiencing embodied cognition. The project also stimulated wider network dissemination of these well-becoming possibilities and pedagogical insights.

    1981-01-01

    A careful evaluation of different production casings used at Cerro Prieto from 1964 to date has shown that the following casings have yielded particularly impressive results: 7 5/8-in. diameter, J-55, 26 lb/ft; 7 5/8-in. diameter, K-55, 45.3 lb/ft; and 5-in. diameter, K-55, 23.2 lb/ft. These casings differ from others of the same diameter but lighter weight which were also used at the field. The results are favorable in spite of severe construction problems, especially the loss of circulation during cementing operations, which we encountered in some of the wells where these casings were used. The use of gravity-fed fine sand as packing material and the arrangement of the production and intermediate casings were important in avoiding damage due to tension-compression stresses and, above all, damage due to internal or external corrosion over time. This situation is clearly evidenced if we compare the damage to the above casings with that experienced by grade N-80 production casings, especially in a corrosive environment.

Investigation was made in cause of lose of nine radiation source in well it is found that all those sources were loss in different depth in the well and with deferent location and there was no risk because there was no contamination of fluids which caused by damage of loss sources. Some recommendations were stated that, if implemented could improve the status of radiation protection in well logging. (Author)

  11. Intelligent sensors for evaluating reservoir and well profiles in horizontal wells : Saudi Arabia case histories

    Horizontal wells are commonly used in Saudi Arabia because they have proven advantages in optimizing production and cost. However, in order to ensure proper production, these wells occasionally require downhole measurements of the flow profile; wellbore parameters such as water entry points; and productivity index for remedial action, such as water shut off or well stimulation. Evaluating the performance of a well also contributes to a better understanding of sweep, water production and cross flow, particularly in long reach wells. The most common flow regime at downhole conditions is a stratified flow regime in which lighter oil flows on top and heavier water flows on bottom. Slugging and bubbling flow regimes are typical of low oil flow rate and are considered unstable flow regimes. This paper described a new generation of production logging tools (PLTs) that have been used on some horizontal wet producers located in Saudi Arabia. The new PLTs consists of arrays of spinners and sensors to log the entire cross section to describe the horizontal flow regime and measure the downhole production and phases. In an effort to find the best logging procedure, the PLT was tested using two methods, notably coiled tubing (CT) and wireline tractor. It was concluded that PLTs are reliable and accurate. Case studies involving planning, deployment, data acquisition, and detailed analysis of PLTs were presented. 35 refs., 1 tab., 20 figs.

  12. Corrosion of well casings in compressed air energy storage environments

    Energy Technology Data Exchange (ETDEWEB)

    Elmore, R.P.; Stottlemyre, J.A.

    1980-10-01

    The goal of this study was to determine corrosive effects of compressed air energy storage (CAES) environments on several well casing materials to aid in material selections. A literature search on corrosion behavior of well casing material in similar environments revealed that corrosion rates of 0.20 to 0.25 mm/y might be expected. This information was employed in designing the laboratory study. Unstressed electrically isolate samples of various carbon steels were autoclaved at varying humidities, temperatures, and exposure durations to simulate anticipated environments in the well bore during CAES operation. All compressed air tests were run at 12.1 MPa. Temperatures varied from 323/sup 0/K to 573/sup 0/K, and humidity varied from 100% to completely dry air. The effects of salts in the humidified air were also studied. Results indicated that typical well casings of carbon steel as used in oil, gas, and water production wells adequately withstand the anticipated CAES reservoir environment. An acceptable corrosion rate arrived at by these laboratory simulations was between 0.0015 and 0.15 mm/y. Corrosion was caused by metal oxidation that formed a protective scale of iron oxide. Higher temperatures, humidity rates, or salinity content of the humid air increased corrosion. Corrosion also increased on a metal coupon in contact with a sandstone sample, possibly due to crevice corrosion. For each of these factors either singularly or collectively, the increased corrosion rates were still acceptable with the maximum measured at 0.15 mm/y. When coupons were reused in an identical test, the corrosion rates increased beyond the anticipated values that had been determined by extrapolation from one-time runs. Fine cracking of the protective scale probably occurred due to thermal variations, resulting in increased corrosion rates and a greater potential for particulates, which could plug the reservoir.

  13. The Business Case for Investing in Physician Well-being.

    Widespread burnout among physicians has been recognized for more than 2 decades. Extensive evidence indicates that physician burnout has important personal and professional consequences. A lack of awareness regarding the economic costs of physician burnout and uncertainty regarding what organizations can do to address the problem have been barriers to many organizations taking action. Although there is a strong moral and ethical case for organizations to address physician burnout, financial principles (eg, return on investment) can also be applied to determine the economic cost of burnout and guide appropriate investment to address the problem. The business case to address physician burnout is multifaceted and includes costs associated with turnover, lost revenue associated with decreased productivity, as well as financial risk and threats to the organization's long-term viability due to the relationship between burnout and lower quality of care, decreased patient satisfaction, and problems with patient safety. Nearly all US health care organizations have used similar evidence to justify their investments in safety and quality. Herein, we provide conservative formulas based on readily available organizational characteristics to determine the financial return on organizational investments to reduce physician burnout. A model outlining the steps of the typical organization's journey to address this issue is presented. Critical ingredients to making progress include prioritization by leadership, physician involvement, organizational science/learning, metrics, structured interventions, open communication, and promoting culture change at the work unit, leader, and organization level. Understanding the business case to reduce burnout and promote engagement as well as overcoming the misperception that nothing meaningful can be done are key steps for organizations to begin to take action. Evidence suggests that improvement is possible, investment is justified, and return

    Casing Drilling{sup TM} is a newly developed and efficient well construction method that combines drilling and casing running processes into a single operation. This radical change to the entire well casing running process eliminates standard components and processes that are inefficient and hazardous. The commercialization of this new technology has resulted in the development of custom equipment and procedures designed to efficiently handle casings on a drilling rig, including conventionally drilled wells. The technology offers safer casing running operations and makes it possible to ream casing to the bottom. In addition, less people are needed to operate the portable Casing Drive System (CDS). One of the primary components of the system is the top drive which provides the power for rotation and torque. The CDS supports full axial and torsional load for running the casing. The well can be circulated while running the casing. The casing can be washed and reamed to the bottom whenever a tight hole is encountered. Thirty one operators have successfully used the CDS on more than 150 onshore and offshore wells in 7 countries. 13 refs., 2 tabs., 12 figs.

  15. Using Horizontal Wells for Chemical EOR: Field Cases

    Full Text Available Primary production of heavy oil in general only achieves a recovery of less than 10% OOIP. Waterflooding has been applied for a number of years in heavy oil pools and can yield much higher recovery but the efficiency of the process diminishes when viscosity is above a few hundreds cp with high water-cuts and the need to recycle significant volumes of water; in addition, significant quantities of oil are still left behind. To increase recovery beyond that, Enhanced Oil Recovery methods are needed. Thermal methods such as steam injection or Steam-Assisted Gravity Drainage (SAGD are not always applicable, in particular when the pay is thin and in that case chemical EOR can be an alternative. The two main chemical EOR processes are polymer and Alkali-Surfactant-Polymer (ASP flooding. The earlier records of field application of polymer injection in heavy oil fields date from the 1970’s however; the process had seen very few applications until recently. ASP in heavy oil has seen even fewer applications. A major specificity of chemical EOR in heavy oil is that the highly viscous oil bank is difficult to displace and that injectivity with vertical wells can be limited, particularly in thin reservoirs which are the prime target for chemical EOR. This situation has changed with the development of horizontal drilling and as a result, several chemical floods in heavy oil have been implemented in the past 10 years, using horizontal wells. The goal of this paper is to present some of the best documented field cases. The most successful and largest of these is the Pelican Lake polymer flood in Canada, operated by CNRL and Cenovus which is currently producing over 60,000 bbl/d. The Patos Marinza polymer flood by Bankers Petroleum in Albania and the Mooney project (polymer, ASP by BlackPearl (again in Canada are also worthy of discussion.

    A number of unconventional sand control completion techniques have been adopted by Petrobras to achieve higher productivity, delay gas/water conning, and to support unconsolidated formations in water injection wells in recently discovered new fields in the Amazon forest and in the deep water offshore Campos Basin. Experiences acquired running screens on 23 horizontal open wells are described. Horizontal wells confirmed the expectations in both locations, i;e. in the Amazon forests water conning was delayed, and in the Marlim field productivity increase to three times that of conventional wells. It was also observed that the API threads used in the screen basepipe for horizontal wells with long radius and short open hole section were adequate, but in the new deep water fields where extended reach wells and long open hole section are likely to be common, it is necessary to use premium threads. 2 refs., 1 tab., 5 figs.

    Full Text Available Drill stem testing of the exploration well consisted of two flow and two pressure build-up periods. Gas was obtained. Modified isochronal test was used during testing the well after completion. Except gas, small quantity of condensate and traces of oil and water were obtained. Both pressure build-up analyses showed that formation permeability is low. DST pressure build-up analysis showed that wellbore damage is present. This was proved later, when acid treatment was performed, by which skin was removed and production increased significantly. Data obtained by well testing are very important for future productivity prediction and determination of optimal well completion and surface facility construction (the paper is published in Croatian.

    2010-01-01

    Full Text Available Casing pipes in oil well constructions may suddenly buckle inward as their inside and outside hydrostatic pressure difference increases. For the safety of construction workers and the steady development of oil industries, it is critically important to measure the stress state of a casing pipe. This study develops a rugged, real-time monitoring, and warning system that combines the distributed Brillouin Scattering Time Domain Reflectometry (BOTDR and the discrete fiber Bragg grating (FBG measurement. The BOTDR optical fiber sensors were embedded with no optical fiber splice joints in a fiber-reinforced polymer (FRP rebar and the FBG sensors were wrapped in epoxy resins and glass clothes, both installed during the segmental construction of casing pipes. In situ tests indicate that the proposed sensing system and installation technique can survive the downhole driving process of casing pipes, withstand a harsh service environment, and remain intact with the casing pipes for compatible strain measurements. The relative error of the measured strains between the distributed and discrete sensors is less than 12%. The FBG sensors successfully measured the maximum horizontal principal stress with a relative error of 6.7% in comparison with a cross multipole array acoustic instrument.

    Full Text Available We report a case of essential segmental myoclonus a 10 year old girl who presented with continuing movement of both the shoulder girdle muscles for 6 months. The movements were exacerbated with the hands raised above the head or in the outstretched posture and were persisting during sleep. There was no abnormal palatal movement. Additionally there was a rhythmical clicking sound arising from the shoulders that could be felt and ausculated with the stethoscope. CT scan of brain and MRI of cervical spine were non-contributory, EMG showed muscle activates at about 50 per second in the shoulder girdle muscles. Cine-radiography of shoulder joints showed the head of humerus hitting against the spine of the scapula rhythmically. Spinal tap was non-contributory. The diagnosis or essential segmental myoclonus was entertained and the subject with fluoxetine, a selective serotonin reuptake inhibitor with remarkable response. The possible mechanism of action of agents modulating the serotonergic system in the brain for the management of myoclonus has been reviewed and their role suggested.

    Steam injection is one of the processes used to increase production from very viscous oil reservoirs. A well is completed at a temperature of about 110 deg F and during steam injection that temperature varies around 600 deg F. Strain or breakdowns may occur to the casing, due to the critical conditions generated by the change of temperature. The usual casing design methods, do not take into account special environmental conditions, such as those which exist for steam injection. From the results of this study we come up to the conclusion that casing grade K-55, heavy weight with premium connections, without pre-stressing and adequately heated, is the best option for steam injection well completion for most of the fields in Brazil.

    Knudsen, S.D.; Sattler, A.R.; Staller, G.E.

    1999-01-01

    Casing deformation in wells is a common problem in many geothermal fields. Casing remediation is necessary to keep wells in production and occasionally, to even enter the well for an approved plug and abandonment procedure. The costly alternative to casing remediation is to incur the expense of drilling a new well to maintain production or drilling a well to intersect a badly damaged well below the deformation for abandonment purposes. The U.S. Department of Energy and the Geothermal Drilling Organization sponsor research and development work at Sandia National Laboratories in an effort to reduce these remediation expenditures. Sandia, in cooperation with Halliburton Energy Services, has developed a low cost, commercially available, bridge-plug-type packer for use in geothermal well environments. This report documents the development and testing of this tool for use in casing remediation work

  10. You say you want a revolution: casing drilling targets 30 per cent well-cost saving

    Energy Technology Data Exchange (ETDEWEB)

    Polczer, S.; Marsters, S.

    1999-10-01

    Casing drilling is a new method of drilling that eliminates drill strings by using standard casing to simultaneously drill and case wells. Tesco Corporation of Calgary acquired patent rights to casing drilling technology in 1995. The company now offers a conversion kit for existing drill rigs as well a new compact casing drilling rig for shallow markets. The single derrick will be rated at 1,500 meters, but initially it will be used to drill 700-800 meter gas wells in southeast Alberta. Some cost savings will be realized at these shallow depths, but the real cost saving advantages will be realized on deep holes. In the meantime, improvements are planned to the cutting structures of the under-rimming bit to increase safety and withstand higher torque loads. It will be also necessary to adapt techniques such as directional drilling and logging to the casing drilling conveyance mechanism which has been only partially successful thus far, especially in the retrieving mode. Another challenge already met, involved ensuring that casing could be run in high-compression loads without damage to connections. Despite these problems, the system attracted considerable attention with several international companies placing orders for immediate delivery. Another system, this one developed by Sperry-Sun Drilling Services and known as a 'casing while drilling' (CWD) system, is strictly a downhole assembly and is targeted for offshore use and deeper vertical holes. This system is currently being tested in two commercial operations in offshore Indonesia for Unocal Corporation. Despite numerous problems to fill casing with fluid during connections, penetration rates of 300-400 feet per hour were achieved.

    Full Text Available Primary liposarcomas of the female and male breasts are very rare. Heterologous differentiation in adipocytic tumors is also an exceedingly rare phenomenon, which is occasionally reported in the literature. We describe the case of a 22 year-old female who presented with a relatively large left breast mass which was clinically diagnosed as a case of giant fibroadenoma, but histologically showed a well differentiated liposarcoma with evidence of extensive chondroid differentiation. The mammographic and radiological features are presented and correlated with the histopathological appearances together with literature review and comparison with similar reported cases.

    Peavy, M.A.; Braun, J.E.

    1991-01-01

    This paper presents an overview of a waste gas treatment system designed to control emissions from thermally enhanced oil recovery wells. This case study discusses the need, design, installation and operations of the system. Oryx Energy Company (Oryx) operates approximately 940 wells in the Midway-Sunset (MWSS) field under casing vapor recovery systems. The emissions collected from well casing vent gas cotaining hydrocarbons and hydrogen sulfide that are collected and processed through casing vapor recovery skids. These skids are composed of condensers, compressors, and pumps that separate fluids from the waste gas stream. The non-condensible gas is then disposed of in incinerators that reduce the hydrocarbon and sulfur emissions into the atmosphere. Approximately 91,000 lbs/day of hydrocarbon and 10,116 lbs/day of sulfur dioxide are removed from the atmosphere from wells contained within these systems operated by Oryx. These hydrocarbons yield approximately 550 barrels of oil per day (BOPD). The system helps manage the pressure differential from the reservoir into each wellbore and contributes to improved ambient air quality in Kern County, California

    Casing leaks have been a major concern to the oil industry because of their effect on lowering the production rate in many oil and gas wells. The leaks are the result of deterioration of the casing in the well, which is caused by severe corrosion due to the contact of the casing with high salinity foreign fluid. The objective of this study is to determine the factors influencing the mechanical properties of the hardened cement opposite the casing leak zones. This study is conducted by laboratory measurements of the compressive strength of the hardened cement when the cement slurry was mixed with different percentages of formation water and different concentrations of different cement additives. The results of this study indicate that the compressive strength readings obtained from the cement bond log and the cement evaluation tool against the casing leak zones are lower than those readings recorded in adjacent formations. The low cement compressive strength values observed across casing leak zones are due to the contamination of the cement with saline water present in these formations which, in turn, effects the hardening properties of the cement. The experimental results indicated that the salinity of the formation water when mixed with the cement slurry in the presence of cement additives, decreased the compressive strength of the bond cement and also decreased the thickening time of the cement slurry. It is concluded that casing leaks found in many wells observed in oil fields in Libya were due to the mixing of the cement with high salinity formation water present in the lost circulation zones. The high water salinity in these zones effects the setting time of the cement slurry which, therefore, decreased the hardening properties of the bond cement and caused cracks and channels in the hardened cement across lost circulation zones.

  16. Not elementary: scientific detectives find industry innocent in most well-poisoning cases

    Oilfield activities are often cited as the source of contamination of water wells. A recent investigation by Alberta Environment Protection found that the problems are in fact due either to poor well maintenance, owner misuse of wells by pumping at a higher rate than their aquifer is capable of yielding, or deterioration due to the age of the wells. In 2000, only three water-well contamination cases were passed on to the Alberta Energy and Utilities Board for follow-ups with oil companies after environmental investigation; in 1999 there was only one case that merited further action after gas was found in a well. Government authorities urge proper construction of wells in the first place, to be followed by preventive maintenance, including testing two or three times a year for bacteriological quality and chemical contamination, regular water analysis, and periodic shock chlorination of the entire well depth, including the distribution system. According to the Petroleum Services Association of Canada (PSAC) the biggest source of well water contamination is not oilfield activity but agricultural activity, specifically the spreading of nitrogen-based fertilizers and manure on farm land which can result in high levels of nitrate, ammonia and bacteria that impact on local soil, surface water, and groundwater. Pesticide spills, feedlots, animal yards, septic systems and water storage areas are other potential sources of contamination in heavily farmed areas. Garbage dumps and landfill sites also may be responsible for well water contamination. Two general types of monitoring for contamination are recommended: primary monitoring where there is potential for underground soil contamination that would not be visible if contamination were to occur, and secondary monitoring of groundwater quality on a broader scale when the likelihood of contamination is suspected. photos

  17. A statistical evaluation of formation disturbance produced by well- casing installation methods

    1988-01-01

    Water-resources investigations concerned with contaminant transport through aquifers comprised of very loose, unconsolidated sediments have shown that small-scale variations in aquifer characteristics can significantly affect solute transport and dispersion. Commonly, measurement accuracy and resolution have been limited by a borehole environment consisting of an annulus of disturbed sediments produced by the casing-installation method. In an attempt to quantify this disturbance and recognize its impact on the characterization of unconsolidated deposits, three installation methods were examined and compared in a sand-and-gravel outwash at a test site on Cape Cod, Massachusetts. These installation methods were: 1) casing installed in a mud-rotary hole; 2) casing installed in an augered hole; and 3) flush-joint steel casing hammer-driven from land surface. Fifteen wells were logged with epithermal neutron and natural gamma tools. Concludes that augering is the most disruptive of the three casing-installation methods and that driving casing directly, though typically a more time-consuming operation, transmits the least amount of disturbance into the surrounding formation. -from Authors

    The temperature inside wells used for gas, oil and geothermal energy production, as well as steam injection, is in general significantly higher than the groundwater temperature at shallower depths. While heat loss from these hot wells is known to occur, the extent to which this heat loss may result in density-driven flow and in mixing of surrounding groundwater has not been assessed so far. However, based on the heat and solute effects on density of this arrangement, the induced temperature contrasts in the aquifer due to heat transfer are expected to destabilize the system and result in convection, while existing salt concentration contrasts in an aquifer would act to stabilize the system. To evaluate the degree of impact that may occur under field conditions, free convection in a 50-m-thick aquifer driven by the heat loss from penetrating hot wells was simulated using a 2D axisymmetric SEAWAT model. In particular, the salinization potential of fresh groundwater due to the upward movement of brackish or saline water in a stratified aquifer is studied. To account for a large variety of well applications and configurations, as well as different penetrated aquifer systems, a wide range of well temperatures, from 40 to 100 °C, together with a range of salt concentration (1-35 kg/m3) contrasts were considered. This large temperature difference with the native groundwater (15 °C) required implementation of a non-linear density equation of state in SEAWAT. We show that density-driven groundwater flow results in a considerable salt mass transport (up to 166,000 kg) to the top of the aquifer in the vicinity of the well (radial distance up to 91 m) over a period of 30 years. Sensitivity analysis showed that density-driven groundwater flow and the upward salt transport was particularly enhanced by the increased heat transport from the well into the aquifer by thermal conduction due to increased well casing temperature, thermal conductivity of the soil, as well as decreased

    A method is provided for resolving undesired fluid flow in cement channels behind casing in one producing zone of a multi zone completion well operating on gas lift from the fluid flow from lower producing zones in the same well which is contained in production tubing passing through the producing zone being investigated. Gamma rays which are characteristic of the decay of the unstable isotope nitrogen 16 produced by activation of elemental oxygen nuclei comprising the molecular structure of both the tubing fluid flow and the undesired fluid flow are detected in at least two energy bonds at two longitudinally spaced detectors in a well borehole. By appropriately combining the four count rate signals so producing according to predetermined relationships the two fluid flow components in the same direction may be uniquely distinguished on the basis of their differing distances from the gamma ray detectors. 9 claims, 17 figures

    Full Text Available Endometrial cancer is the 6-th most common malignancy in women worldwide, accounting for about 4.8 % of all female cancers. The treatment of recurrent endometrial cancer remains a major challenge. Some endometrial cancer recurrences, for example vaginal stump recurrence, are reported to be effectively treated with surgical resection and radiation therapy. Early recurrence of early-stage well-differentiated endometrial cancer is uncommon. Case report. Herein we report a rare case of recurrent well-differentiated endometrial cancer in a 65-year-old woman. The patient had recurrence 10 months after laparoscopic hysterectomy with bilateral salpingo-oophorectomy. Recurrent endometrial tumor with extension into the rectosigmoid colon, urinary bladder and the right ureter manifested itself clinically with severe pain requiring the use of opioids. The recurrent tumor was removed. Resection of the bladder, left ureter and upper ampular rectum was followed by anastomosis. The patient received multiple cycles of chemotherapy. Conclusion. Compliance with the principles of ablastics during the laparoscopic or laparotomic surgery helps to avoid recurrence in patients with prognostically favorable cancer. In case of recurrence, combined operations are the only possible chance of improving survival of patients with locally advanced or recurrent tumors, which are insensitive to chemoradiotherapy.

    A horizontal well can be geologically steered using a forward modelling geosteering software that helps determine the stratigraphic position of the drillstring and interpret the well in the reservoir. The software shows reservoir engineers how to maximize the pay zone, optimize the well path, characterize reservoir properties and avoid entering undesired beds or fluid contacts. The best way to maximize the pay zone is to use an integrated arrangement of formation evaluation tools, software and reservoir engineering expertise. This paper presents a series of measurements while drilling and logging. Drilling (MWD/LWD) tools obtain real-time data and forward modelling while drilling software. When interpreted by a trained specialist, these tools help in decision making processes regarding reservoir depletion. The paper presents a case study from offshore eastern Canada in which a well was drilled horizontally from a semi-submersible mobile drilling unit. StrataSteer {sup TM}, a software tool developed by Halliburton Energy Services, was used to interpret the LWD data. The software is compatible with other downhole tools and the INSITE information system which provides real-time data. The objective of the study is to demonstrate the capabilities of the forward modelling tool while drilling the well. A computer was set up at the client's office and at the offshore rig site. The geological model which was constructed using the acquired data was then used to make real-time collaborative decisions to land the well correctly in the reservoir, maximize the productive interval, optimize the well path, and analyze the reservoir properties. However, it was noted that due to geological uncertainty, the objectives in this well were not achieved. 6 figs.

    Cementation of in-situ combustion (ISC) wells is challenging since wells are frequently associated with weak and unconsolidated formation. However, cement rise up to surface is desired to prevent casing failure. Moreover, the cement sheath is also required to withstand extreme stresses due to high temperature cycling experienced during in-situ combustion process. In response to the problem of inadequate placement time and flash setting, Portland cement-silica blends were used for cementation of ISC wells in India instead of alumina cement blends. However, the use of the cement-silica blends has resulted in insufficient cement rise because of losses during cementation. The cured cement failed to contain the strength and permeability in course of ISC process causing charge of sub-surface shallower layers. This paper discussed the development and implementation of a non-alumina based thermally stable lightweight lead slurry and a ductile high temperature resistance tail slurry for mitigating these problems. The paper provided details of the study as well as four successful case histories. The cementing practice for ISC wells around the world was first described and illustrated. Next, the paper outlined the formulation of thermally stable tail slurry through laboratory studies. Slurry parameters of the tail slurry were presented, including slurry weight; thickening time; fluid loss; free fluid; and rheology. The paper also reviewed a study of compressive strength and permeability of thermal slurry; slurry parameters of the lightweight lead slurry; and study of compressive strength and permeability of lightweight thermal slurry. 8 refs., 4 tabs., 12 figs.

  3. Well materials durability in case of carbon dioxide and hydrogen sulphide geological sequestration

    The geological sequestration of carbon dioxide (CO 2 ) and hydrogen sulphide (H 2 S) is a promising solution for the long-term storage of these undesirable gases. It consists in injecting them via wells into deep geological reservoirs. The steel and cement employed in the well casing can be altered and provide pathways for leakage with subsequent human and environmental consequences. The materials ageing was investigated by laboratory experiments in geologically relevant P-T conditions. A new experimental and analysis procedure was designed for this purpose. A numerical approach was also done. The cement and steel were altered in various fluid phases at 500 bar-120 C and 500 bar-200 C: a brine, a brine saturated with H 2 S-CO 2 , a mixture of brine saturated with H 2 S-CO 2 and of supercritical H 2 S-CO 2 phase, a dry supercritical H 2 S-CO 2 phase without liquid water. In all cases, two distinct reactions are observed: the cement carbonation by the CO 2 and the steel sulfidation by the H 2 S. The carbonation and sulfidation are respectively maximal and minimal when they occur within the dry supercritical phase without liquid water. The textural and porosity properties of the cement are weakly affected by all the treatments at 120 C. The porosity even decreases in presence of H 2 S-CO 2 . But these properties are affected at 200 C when liquid water is present in the system. At this temperature, the initial properties are only preserved or improved by the treatments within the dry supercritical phase. The steel is corroded in all cases and thus is the vulnerable material of the wells. (author)

    Optimization is one of the tools available to assist decision makers in balancing multiple objectives and concerns. In a case study of the siting decision for groundwater monitoring wells, we look at the influence of the optimization models on the decisions made by the responsible groundwater specialist. This paper presents a multi-objective integer programming model for determining the location of monitoring wells associated with a groundwater pump-and-treat remediation. After presenting the initial optimization results, we analyze the actual decision and revise the model to incorporate elements of the problem that were later identified as important in the decision-making process. The results of a revised model are compared to the actual siting plans, the recommendations from the initial optimization runs, and the initial monitoring network proposed by the decision maker

    Well's syndrome, or eosinophilic cellulitis, is rare in childhood, with fewer than 40 pediatric cases being reported since 1979. The physiopathology is unknown. In February 2012, members of the research group of the Department of Pediatric Dermatology Society submitted their case of Wells' syndrome in children aged 0-15 years. Details of clinical, biological and histological features and of therapeutic strategies were collected by physicians using a standardized questionnaire. Pictures were reviewed by the authors. Eleven patients were included (average age: 6 years), with a strong prevalence of atopy (63%). Two types of clinical manifestation were noted: single or multiple cellulitis associated or not with vesiculobullous lesions and fixed urticaria. Eighty-two percent of patients had pruritus and 73% had eosinophilia. For all patients, histological examination of skin biopsies showed an eosinophilic infiltrate extending in the dermis with associated Sweet-like neutrophilic infiltrate being seen in 2 patients. The course of the disease was protracted (mean duration: 8 months) with flare-ups. Treatment varied depending on the doctors (topical or systemic steroids, tacrolimus and dapsone). Our study confirms some of the data in the literature concerning the clinical, histological features and course of Well's syndrome in children. The key information is the high prevalence of atopic children hitherto unreported. In a setting of insect bites, vaccination, infection or traumatism, this unusual background could explain the onset of inflammatory reaction with eosinophils. Oral or topical steroids appear to be the first-line treatment in children when necessary. Well's syndrome in children is rare and characterized by its polymorphism. We report for the first time in a series of patients a high prevalence of atopy, which raises new perspectives in understanding these rare diseases. We propose topical steroids as first-line therapy in children with superficial lesions

    This paper provides an overview of the automated disposal system for produced water designed and operated by Taurus Exploration, Inc. This presentation draws from Taurus' case study in the planning, design, construction, and operation of production water disposal facilities for the Mt. Olive well field, located in the Black Warrior Basin of Alabama. The common method for disposing of water produced from coalbed methane wells in the Warrior Basin is to discharge into a receiving stream. The limiting factor in the discharge method is the capability of the receiving stream to assimilate the chloride component of the water discharged. During the winter and spring, the major tributaries of the Black Warrior River are capable of assimilating far more production water than operations can generate. During the summer and fall months, however, these same tributaries can approach near zero flow, resulting in insufficient flow for dilution. During such periods pumping shut-down within the well field can be avoided by routing production waters into a storage facility. This paper discusses the automated production water disposal system on Big Sandy Creek designed and operated by Taurus. This system allows for continuous discharge to the receiving stream, thus taking full advantage of Big Sandy Creek's assimilative capacity, while allowing a provision for excess produced water storage and future stream discharge

    Most studies in adults with developmental dyslexia have focused on identifying the deficits responsible for their persistent reading difficulties, but little is known on how these readers manage the intensive exposure to written language required to obtain a university degree. The main objective of this study was to identify certain skills, and specifically vocabulary skills, that French university students with dyslexia have developed and that may contribute to their literacy skills. We tested 20 university students with dyslexia and 20 normal readers (matched on chronological age, gender, nonverbal IQ, and level of education) in reading, phonological, vocabulary breadth (number of known words), and vocabulary depth (accuracy and precision) tasks. In comparing vocabulary measures, we used both Rasch model and single case study methodologies. Results on reading and phonological tasks confirmed the persistence of deficits in written word recognition and phonological skills. However, using the Rasch model we found that the two groups performed at the same level in the vocabulary breadth task, whereas dyslexics systematically outperformed their chronological age controls in the vocabulary depth task. These results are supplemented by multiple case studies. The vocabulary skills of French university students with dyslexia are well developed. Possible interpretations of these results are discussed.

  9. Detection of behind casing water flow at an angle to the axis of a well borehole

    International Nuclear Information System (INIS)

    1980-01-01

    Methods and apparatus for detecting the undesired flow of water in cement channels or voids behind the casing in a producing well are described. A source of high-energy neutrons (approx. 14 MeV) is placed inside the well borehole opposite the area to be investigated for cement channelling, and used to irradiate the area. An oxygen 16 nucleus is transmuted upon capture of an approximately 10 MeV neutron to radioactive nitrogen 16. This decays with a half life of 7.1 sec by emission of a beta particle and high energy gamma rays. With a sufficiently high flux of bombarding neutrons enough nitrogen 16 is created to be detected at a pair of longitudinally spaced detectors. This measurement can be used directly to indicate the speed of flow of water in the cement channels. However the volume flow rate can be determined from the detection of the high energy gamma rays from the decay of the nitrogen 16. If a pulsed neutron source is used a more accurate detection is provided. The angle of flow can be determined by suitable instrumentation. Full specifications are given. (U.K.)

    The purpose of this study is to determine if giant size is of bad prognosis in deep lipomas of the upper extremity. We report a retrospective study of 13 patients with deep-seated lipomas of the upper extremity treated during the period from April 1997 to April 2008. We evaluated the clinical and radiological characteristics, treatment and evolution profile of these patients. There were 10 women and three men, with an average age of 53 years (range 30-79 years). Seven of these lipomas were in the arm, one in the shoulder, and five in the forearm. Six lipomas were intramuscular, six intermuscular (three of them being attached to bone and labelled parosteal lipoma) and one epivaginal lipoma of the flexor tendon sheath. All patients presented a progressive slow-growing mass that was associated with radial paralysis in one case and carpal tunnel syndrome in one case. Plain radiographs showed a radiolucent soft-tissue image in all cases and an associated osteochondroma in one parosteal lipoma. Computer tomography (CT) or magnetic resonance imaging (MRI) suggested the lipomatous nature and benign characteristics of these deep lipomas that were giant in all cases (mean size: 7 cm). Lipoma marginal excision was performed and histopathological examination demonstrated features consistent with a benign lipoma. There was good function and no clinical recurrence was observed after a mean follow-up of three years. Giant deep-seated lipomas of the upper extremity are uncommon and can be intermuscular or intramuscular. A painless soft-tissue mass is the most frequent chief complaint. MRI with fat suppression suggests the diagnosis and studies the extension of deep lipoma. Marginal excision is the treatment of choice and histopathology eliminates diagnosis of well-differentiated liposarcoma. Appropriate evaluation of deep lipoma is to rule out malignancy by systematically performing MRI and biopsy. In contrast to deep-seated lipomas of the lower extremity or the retroperitoneal

    2018-02-01

    Full Text Available Horizontal shale gas well fracturing is mostly carried out by pumping bridge plugs. In the case of casing deformation, the bridge plug can not be pumped down to the designated position, so the hole sections below the deformation could not be stimulated according to the design program. About 30% of horizontal shale gas wells in the Changning and Weiyuan Blocks, Sichuan Basin, suffer various casing deformation after fracturing. Previously, the hole sections which could not be stimulated due to casing deformation were generally abandoned. As a result, the resources controlled by shale gas wells weren't exploited effectively and the fracturing effect was impacted greatly. There are a lot of difficulties in investigating casing deformation, such as complex mechanisms, various influencing factors and unpredictable deformation time. Therefore, it is especially important to seek a staged fracturing technology suitable for the casing deformation sections. In this paper, the staged fracturing technology with sand plugs inside fractures and the staged fracturing technology with temporary plugging balls were tested in casing deformation wells. The staged fracturing technology with sand plugs inside fractures was carried out in the mode of single-stage perforation and single-stage fracturing. The staged fracturing technology with temporary plugging balls was conducted in the mode of single perforation, continuous fracturing and staged ball dropping. Then, two kinds of technologies were compared in terms of their advantages and disadvantages. Finally, they were tested on site. According to the pressure response, the pressure monitoring of the adjacent wells and the microseismic monitoring in the process of actual fracturing, both technologies are effective in the stimulation of the casing deformation sections, realizing well control reserves efficiently and guaranteeing fracturing effects.

    About 3-4% of all pregnant women will have a fetus presenting by the breech at term. External cephalic version offers the opportunity to reduce the rate of caesarean sections caused by breech presentation. We analysed retrospectively 51 cases of external cephalic version at our clinic. External cephalic version was performed 51 times between 37 and 41 weeks of pregnancy. External cephalic version was successful in 32/51 cases (62,7%) with a consecutive rate of vaginal delivery of 71,9%. The best results were seen at 37 weeks of pregnancy with 81,25% of successful versions followed by 76,9% of vaginal deliveries. Complications were rare. There was just 1 case of emergency caesarean section due to persisting fetal bradycardia. External cephalic version is an effective and safe treatment to enable vaginal delivery of cephalic presentation. For this operation, 37 weeks of pregnancy can be considered the best time. 2009 S.

    2011-01-01

    Radon concentration was monitored during the flow tests of well IC-09 at the Chingshui geothermal field. The radon concentration was found to increase from 54 ± 29 to 983 ± 65 Bq/m 3 as a step function of production time, or cumulative production. The observed radon behavior can be explained by a radial composite model with the carbonate scales deposited in the skin zone near the well. The radius of skin zone near well IC-09 can be estimated with radon data at about 20 m using a plug flow model. Monitoring natural radon during the well flow tests is a helpful tracer to diagnose the formation damage near the well.

    National Colombian Petroleum Company - ECOPETROL, is in the process of evaluating different technologies to increase production and improve recovery factors in their mature oil and gas fields. As part of that process, a multidisciplinary team evaluated the feasibility of multilateral well technology implementation in some of their mature fields that are currently in the late-development phase. Castilla field, located in the eastern planes of Colombia, was selected as the first option for multilateral technology implementation based in reservoir features, type of oil, and field antecedents. This paper presents the process used to conceptualize the optimum multilateral well design for Castilla field, integrating all of the geological and engineering disciplines. Geology: geological model visualization, target zones definition, pay zones lateral continuity, petrophysical properties, and fluids distribution were evaluated to select the areas to drill with advanced architecture well design. Reservoir: basic reservoir performance simulation was performed to evaluate productivity with horizontal and multilateral wells, and the difference in final reserves recovery compared with current conventional directional wells. Water production and coning problems were identified as key factors to define the multilateral well implementation in this field. Drilling: trajectory design, multilateral junction depth definition and TAML level selection, casing point's definition, drilling time and AFE estimation were the technical aspects evaluated during the planning phase to determine if the technology would be feasible. A comparison with conventional pad design was conducted to validate economic value. Multilateral TAML level 4 system selection flow process is presented applying oil industry best practices. Completion: The optimum lateral completion and production assembly design were main concerns during the planning process. Slotted liners, screens, and open-hole completion

    The strategy adopted and the factors considered in the development of the sandface completion design for Phase One of the Harding Field in the unconsolidated Balder Massive Sand in the U.K. Sector of the North Sea is described. The field development utilizes a TPG 500 Jack-up Drilling and Production Unit in conjunction with a concrete gravity base tank (GBT). The first phase of the development involved drilling and completing horizontal wells sand-free, ultra-high production (over 30,000 BOPD/well, with PI in excess of 1,000 bbl/day/psi). The experiences showed that pre-packed screens can be successfully utilized to provide lasting sand control with high rate of production in clean homogenous sandstones, and that testing for fluid compatibility, formation damage, screen plugging, corrosion and erosion potential are essential pre-requisites in determining the optimal solution in any well with sand production potential.The experiences gained in Phase One have contributed to design enhancements for Phase Two of the project which include extended reach horizontal wells to neighbouring satellite pools. 3 refs., 1 tab., 8 figs.

    Work in the field of sexual abuse is extremely stressful and may arouse negative personal reactions. Although these secondary trauma effects are well described on a personal level, there is not enough evidence to understand whether these professionals carry these effects to their homes, families, and offspring. This study aims to identify the effects of working with child abuse cases on the anxiety level and parenting styles of childhood trauma workers and on their children's well-being. A total of 43 health and legal system workers who worked with abused children in any step of their process and who had children constituted the study group, and 50 control cases, each working in the same institution and having the same occupation as 1 of the participants from the study group and having children but not working directly with children and child abuse cases, were included in the study. Participants were asked to fill out a sociodemographic form, the Parental Attitude Research Instrument, the trait portion of the State-Trait Anxiety Inventory, and an age-appropriate form of the Child Behavior Checklist for each child they had. Professionals in the study working with child abuse cases demonstrated significantly higher democratic parenting attitudes. Law enforcement workers working with child abuse cases demonstrated stricter and more authoritarian parenting strategies, as well as more democratic attitudes, than their colleagues. There was not a statistically significant relationship between child abuse workers' anxiety level and their children's well-being among control subjects.

    2011-01-01

    Nuclear well logging, including natural gamma ray, density, and neutron-porosity techniques are used with electrical well logging of long and short normal techniques to characterize the basaltic areas largely extended in Southern Syria. Statistical analysis approach with the threshold concept has been adapted for such characterization, where four kinds of basalt have been identified: very hard basalt, hard basalt, fractured basalt, and basalt alteration products. The spectrometric gamma technique has also been applied on the retrieved rock samples in order to determine the radioactive content (eU, eTh, and K%) of the basaltic section in the study area. No radioactive anomalies have been detected, the radioactive values are normal and in the expected range.

  9. The case for exploring the usage of employee wellness programs for pediatric asthma control.

    Science.gov (United States)

    Jassal, Mandeep S; Butz, Arlene

    2018-01-18

    The multiple socioecological determinants of asthma mandate that pediatricians develop a treatment strategy beyond the practice-based setting. To expand to a more impactful community-based role, pediatricians must look to form partnerships with groups that are capable of promoting social and environmental change. Traditionally, these groups have included schools, governmental agencies, and child care establishments. One group that is not actively being availed of are employers who have shown success in improving adult-based outcomes through wellness programs. Employers are stakeholders in pediatric asthma care through its impact on reduced worker productivity and higher health insurance premiums. An employer's focus on pediatric asthma will be a collective win for the employer and employee. The article herein describes the rationale for the focus of employers on pediatric asthma care and potential incorporation within employer-based wellness strategies.

    2015-02-01

    Full Text Available The Ratkovce 1 well, drilled in the Blatné depocenter of the northern Danube Basin penetrated the Miocene sedimentary record with a total thickness of 2000 m. Biostratigraphically, the NN4, NN5 and NN6 Zones of calcareous nannoplankton were documented; CPN7 and CPN8 foraminifer Zones (N9, 10, 11 of the global foraminiferal zonation; and MMi4a; MMi5 and MMi6 of the Mediterranean foraminiferal zonation were recognized. Sedimentology was based on description of well core material, and together with SP and RT logs, used to characterize paleoenvironmental conditions of the deposition. Five sedimentary facies were reconstructed: (1 fan-delta to onshore environment which developed during the Lower Badenian; (2 followed by the Lower Badenian proximal slope gravity currents sediments; (3 distal slope turbidites were deposited in the Lower and Upper Badenian; (4 at the very end of the Upper Badenian and during the Sarmatian a coastal plain of normal marine to brackish environment developed; (5 sedimentation finished with the Pannonian-Pliocene shallow lacustrine to alluvial plain deposits. The provenance analysis records that the sediment of the well-cores was derived from crystalline basement granitoides and gneisses and from the Permian to Lower Cretaceous sedimentary cover and nappe units of the Western Carpathians and the Eastern Alps. Moreover, the Lower Badenian volcanism was an important source of sediments in the lower part of the sequence.

    This study evaluates inorganic pigments for improving carbon steel (CS) brine-corrosion protection by the sodium metasilicate-activated calcium aluminate cement/Fly Ash blend at 300°C. Calcium borosilicate (CBS) and zinc phosphate, significantly improved CS corrosion-protection by decreasing cement’s permeability for corrosive ions and inhibiting anodic corrosion. An amorphous Na2O-Al2O3-SiO2-H2O phase tightly attached to CS surface formed at 300oC in CBS-modified cement pore solution. The corrosion rate of the CS covered with this phase was nearly 4-fold lower than in the case of nonmodified cement pore solution where the major phase formed on the surface of CS was crystalline analcime.

    2018-01-01

    Well-differentiated papillary mesothelioma is a rare tumor occurring predominantly in the peritoneum of young women, a few with history of asbestos exposure. A 28-year-old woman presented with ascites and pain abdomen. Ultrasonography and computed tomography scan of the abdomen revealed a mass in the retroperitoneum measuring 15 cm × 12 cm. Histopathological examination along with immunohistochemistry (IHC) confirmed it to be a papillary mesothelioma in the peritoneum. It is difficult to differentiate from more common malignant mesothelioma and papillary adenocarcinoma, which also have poorer prognosis. The difficulty can be resolved by clinico-radiological correlation along with histopathological examination and IHC.

  18. Living Together v. Living Well Together: A Normative Examination of the SAS Case

    Directory of Open Access Journals (Sweden)

    Lori G. Beaman

    2016-04-01

    Full Text Available The European Court of Human Rights decision in SAS from France illustrates how a policy and national mantra that ostensibly aims to enhance inclusiveness, ‘living together’, is legally deployed in a manner that may have the opposite effect. In essence, despite acknowledging the sincerity of SAS’s religious practice of wearing the niqab, and her agency in making the decision to do so, the Court focuses on radicalism and women’s oppression amongst Muslims. Taking the notion of living together as the beginning point, the paper explores the normative assumptions underlying this notion as illustrated in the judgment of the Court. An alternative approach, drawing on the work of Derrida for the notion of ‘living well together’ will be proposed and its implications for social inclusion explicated. The paper’s aim is to move beyond the specific example of SAS and France to argue that the SAS pattern of identifying particular values as ‘national values’, the deployment of those values through law, policy and public discourse, and their exclusionary effects is playing out in a number of Western democracies, including Canada, the country with which the author is most familiar. Because of this widespread dissemination of values and their framing as representative of who ‘we’ are, there is a pressing need to consider the potentially alienating effects of a specific manifestation of ‘living together’ and an alternative model of ‘living well together’.

    2016-09-01

    Allotments in the UK are popular and waiting lists long. There is, however, little evidence on the health benefits of allotment gardening. The aims of this study were to determine the impacts of a session of allotment gardening on self-esteem and mood and to compare the mental well-being of allotment gardeners with non-gardeners. Self-esteem, mood and general health were measured in 136 allotment gardeners pre- and post- an allotment session, and 133 non-gardener controls. Allotment gardeners also detailed the time spent on their allotment in the current session and previous 7 days, and their length of tenure. Paired t-tests revealed a significant improvement in self-esteem (P 0.05). One-way ANCOVA revealed that allotment gardeners had a significantly better self-esteem, total mood disturbance and general health (P gardening can play a key role in promoting mental well-being and could be used as a preventive health measure. © The Author 2015.

    2015-07-03

    Mental health difficulties are connected with major interpersonal and social challenges. Recent qualitative research indicates that music therapy can facilitate many of the core elements found to promote social recovery and social inclusion, findings also reflected in results from a growing body of effect studies. The objective of this study was to explore how music therapy might afford possibilities for social recovery to one man with psychosis admitted to a psychiatric intensive care unit. This was achieved by means of a qualitative case study featuring a description of the music therapeutic process alongside first-hand accounts of the participant's subjective experiences. The data were analysed using interpretative phenomenological analysis (IPA). The findings are presented in a narrative form reflecting processes and activities considered particularly important for the process of social recovery. Theoretical perspectives from the recovery literature and current perspectives in music therapy are discussed with a view to the possible use of music therapy for strengthening agency, (re)building identity, developing positive relationships, and expanding social networks.

  2. A case of Bowen’s disease responding well to radiotherapy

    2013-08-01

    Full Text Available Bowen’s disease is a form of intraepidermal squamous cell carcinoma which is known as carsinoma in situ. The head, neck, and extremities are the most commonly affected anatomic locations. Treatment options for Bowen’s disease include observation, surgery, cryotherapy, electrodesiccation and curettage, topical application of 5-fluorouracil or imiquimod, Moh’s micrographic surgery, photodynamic therapy, and radiotherapy. Radiation therapy is advantageous in patients who refuse surgery, for large or multiple lesions, for lesions in cosmetically sensitive areas, and in patients who are predisposed to formation of keloids, with a high cure rate cited in the literature. Here we report a 70-year-old man who was diagnosed as Bowen’s disease and completely healed with the treatment of radiotherapy. By means of this case report, we will review the current literature and empasize that radiotherapy is an effective treatment alternative for Bowen's disease in the suitable lesions.

    Thomas, D.M.

    1982-01-01

    The Hawaii Geothermal Project Well-A, located on the island of Hawaii, was completed in 1976 to a depth of 1966 meters. The bottomhole temperature, under shut-in conditions, is 360 0 C and at full discharge is capable of producing about 45,500 kg/hr of a mixed fluid composed of 48% steam and 52% liquid. The major element chemistry of the fluids suggests that recharge to the reservoir is largely fresh meteoric water with no more than 10% to 15% of the recharge being from sea water. Extensive water-rock equilibration has occured; however neither Na-K-Ca nor silica geothermometry calculations have been able to yield reasonable reservoir temperatures. Isotopic data suggest that the circulation rate and residence times of fluids in the reversoir are on the order of a few thousand years. Helium isotopic data also indicate that the heat source for this reservoir is very young or very large

  5. Unusually well preserved casts of halite crystals: A case from the Upper Frasnian of northern Lithuania

    Rychliński, Tomasz; Jaglarz, Piotr; Uchman, Alfred; Vainorius, Julius

    2014-07-01

    Upper Frasnian carbonate-siliciclastics of the Stipinai Formation (northern Lithuania) comprise a bed of calcareous silty arenite with casts of halite crystals, including hopper crystals. Unusually well-preserved casts occur on the lower surface of the bed, while poorly-preserved casts are present on the upper bedding surface. The casts originated as the result of the dissolution of halite crystals which grew in the sediment. The dissolution took place during early stages of diagenesis, when host sediment was soft. Unstable cavities after crystal dissolution were filled by overlying sediment forming their casts. The collapsing sediment form sink-hole deformation structures which disturb wave-ripple cross lamination from the upper part of the bed. Dewatering pipe structures are also present. The casts and accompanying sink-hole and dewatering pipes are classified as the postdepositional deformation structures caused by haloturbation.

  6. Cased Hole Evaluation Using Pulsed Neutron measurements and remedial actions on non-performing wells

    International Nuclear Information System (INIS)

    Mukerji, P.

    2002-01-01

    Advances in pulsed neutron spectroscopy tools have improved accuracy and precision of measured carbon-oxygen rations. The C/O ratios relate to the volumes of oil and water in the formation. Some of the improvements in accuracy and precision have resulted from better tool characterization in a wider variety of logging environments in the calibration facility and new spectral standards. The ability to combine advanced logging measurements has provided the operator with better diagnosis tools for identifying candidates for possible remedial actions. The successful diagnosis and treatment of water production problems requires the identification of specific influx zones. The information obtained from such logs allows effective treatment of unwanted wellbore fluid entries. This paper will present examples from logs run in the Niger delta. We will show how the application of pulsed neutron logs can optimise subsequent well intervention to reduce water production and/or increase oil production

In this article, we present three different but complementary views - those of an advocate, an employer and a provider - on helping employees maintain mental, and physical, health. In the first section, Sari Sairanen outlines programs and services to manage stress and maintain mental health that have been developed by the Canadian Auto Workers' union and implemented in partnership with employers, wellness providers, service agencies and other community partners. The union focuses on raising awareness and providing education, as well as removing the stigma associated with mental illness. Deanna Matzanke, in her section, discusses the commitment of a company, Scotiabank, to create and maintain an inclusive and accessible workplace for all its employees. It has recently worked with providers to develop and implement integrated services dealing specifically with mental health illness and addiction, which aid not only its current employees but also possible future employees. Finally, Doug Smeall shares his observations as an insurer at Sun Life Financial, who has seen the rates of both short-term and long-term disabilities increase. He elaborates on the collaborative work between insurers and employers to help employees maintain their mental health, and to return to work sooner when issues do occur. Ultimately, this article argues that unions, employers and insurers can work together with partners and employees to promote and maintain employee health because, as Sairanen asserts, "preventing a problem in the first place is the best strategy."

    This paper discussed the challenges facing horizontal well drilling with particular reference to the limited success rates of 2 wells that were initially planned and drilled geometrically according to integrated geological and seismic data. The limited success was due partly to drilling to target without considering the key subsurface risks and uncertainties at the execution stages of the wells. Two case studies from these fields were presented in an effort to highlight important geological issues that must be considered when planning and executing horizontal wells. While the wells were being drilled, geological decisions were taken based on seismic data, geological modelling and assessing offset well log responses. The continuous use of real-time data during well drilling contributed to the achievement of the wells' objectives. This approach eliminated all the initial assumptions from seismic data. During the planning stages, many target surfaces such as faults, horizons and unconformities were created from a 3 dimensional grid. Each well was geologically steered in the execution stages by comparing what was seen while drilling with what was initially proposed at the planning stages. As drilling progressed, geological issues such as structural, stratigraphic, reservoir fluid contact and surveying uncertainties were considered. In most instances, the geological objectives of the studied wells were met, thereby improving production, increasing net pay and return on investment. It was concluded that the experience from this work can be applied to oilfields anywhere in the world.

    Twenty years have passed since the publication of the seminal paper 'The salutogenic model as a theory to guide health promotion' (Health Promot Int 1996;11:11-18.), in which Antonovsky proposed salutogenesis and its central construct sense of coherence as a way of boosting the theoretical basis for health promotion activities. Since then there has been a notable amount of conceptual and empirical work carried out to further explore its significance. The aim of this paper is to critically assess the current theoretical status of salutogenesis and its utility to advance effective health promotion practice for young people. The assessment was carried out in the context of contemporary international policy agendas on well-being. An analytic framework was developed using the previous literature on the definition and function of theory. This organizing framework comprised four criteria: description, explanation, prediction and measurability. The paper concludes with a perspective on the status of salutogenesis as a theory and how it can be further developed. Specifically, the critical assessment highlighted that salutogenesis has been subjected to considerable empirical testing over the last few decades resulting in convincing evidence of the relevance and subsequent advancement of the idea. However, less emphasis seems to have been placed on a systematic process of testing and iteration to develop its theoretical basis. The paper identifies a number of aspects that should be developed to support the progression of salutogenesis to the next level. A research-practice cycle approach is proposed that can facilitate that important next step. © The Author 2016. Published by Oxford University Press. All rights reserved.

    Today, the most effective liquid-removal devices are pumping, the combination of liquid-diverter with gas lift and velocity string. Considering mentioned complexities, the most efficient method of liquid removal is different from one well to the others. This paper discusses a multi-criteria decision making (MCDM strategy for ranking these methods based on ELECTRE and TOPSIS techniques in a gas condensate reservoir. The most efficient model in this case, regarding its high efficiency and level of reliability is continuous gas lift. These procedures can be extended to other cases easily by changing the comparison matrix and user defined weights.

  12. Technology of double casing tubes & a binary cycle system for hole cleaning for CBM multi-branch horizontal wells

    2017-03-01

    Full Text Available At present, the aeration-assisted cutting-carrying technology is faced with complexities in the drilling of CBM multi-branch horizontal wells. For example, the aerating pressure is hardly maintained, and the borehole instability may happen. In view of these prominent problems, the technology of double casing tubes & a binary cycle system suitable for CBM multi-branch horizontal wells was developed according to the Venturi principle by means of parasitic tube insufflation which is used for well control simulation system. Then, a multiphase flow finite element model was established for the fluid-cutting particle system in this drilling condition. This technology was tested in field. Double-casing tubes cementing is adopted in this technology and a jet generator is installed at the bottom of the inner casing. In the process of drilling, the drilling fluid injected through double intermediate casing annulus is converted by the jet generator into a high-efficiency steering water jet, which, together with the water jet generated by the bit nozzle, increases the fluid returning rate in the inner annulus space. It is indicated from simulation results that the cutting-carrying effect is the best when the included angle between the nozzle of the jet generator and the vertical direction is 30°. Besides, the influential laws of cutting size, primary cycle volume, accessory cycle volume and drilling velocity on hole cleaning are figured out. It is concluded that this technology increases the flow rate of drilling fluid in annulus space, the returning rate of drilling fluid significantly and the cutting-carrying capacity. It is currently one of the effective hole cleaning technologies for CBM multi-branch horizontal wells where fresh water is taken as the drilling fluid.

  15. Strange Case of Dr. Jekyll and Mr. Hyde-was Robert Louis Stevenson inspired by Horace Wells?

    2015-01-01

    It has been suggested that Robert Louis Stevenson's masterpiece Strange Case of Dr. Jekyll and Mr. Hyde derived inspiration from the real-life tragedy of the final days of Connecticut dentist Horace Wells, innovator of the clinical use of the anesthetic properties of nitrous oxide. We examined Stevenson's letters, biographies, and other references in the literature, press, and online to determine whether any factual basis exists for Stevenson to be aware of Wells' life, and also if it played any role in creating the novel's plot. Stevenson was born in Scotland, several years after Wells had committed suicide in New York. Wells' life and death received widespread coverage in the northeastern United States, but there is no evidence that it was printed in newspapers or periodicals in England or Scotland. On the other hand, novelists of the period, psychologists, and the lay public were quite interested in the concept of split personalities and the dual nature of man, so these may have been natural substrates for the novel. There is evidence that Stevenson dreamt about episodes similar to those depicted in his novel. All claims to any relationship between Wells and the novel come from the United States, and none of them are backed by evidence. In the absence of evidence supporting a relationship between the behavior exhibited by Wells during his final days and any inspiration that Stevenson might have derived from it, we conclude that there is insufficient evidence to suggest any relationship between them.

    Seismic wave velocities, along with petrophysical data, provide valuable information during the exploration and development stages of oil and gas fields. The compressional-wave velocity (VP ) is acquired using conventional acoustic logging tools in many drilled wells. But the shear-wave velocity (VS ) is recorded using advanced logging tools only in a limited number of wells, mainly because of the high operational costs. In addition, laboratory measurements of seismic velocities on core samples are expensive and time consuming. So, alternative methods are often used to estimate VS . Heretofore, several empirical correlations that predict VS by using well logging measurements and petrophysical data such as VP , porosity and density are proposed. However, these empirical relations can only be used in limited cases. The use of intelligent systems and optimization algorithms are inexpensive, fast and efficient approaches for predicting VS. In this study, in addition to the widely used Greenberg–Castagna empirical method, we implement three relatively recently developed metaheuristic algorithms to construct linear and nonlinear models for predicting VS : teaching–learning based optimization, imperialist competitive and artificial bee colony algorithms. We demonstrate the applicability and performance of these algorithms to predict Vs using conventional well logs in two field data examples, a sandstone formation from an offshore oil field and a carbonate formation from an onshore oil field. We compared the estimated VS using each of the employed metaheuristic approaches with observed VS and also with those predicted by Greenberg–Castagna relations. The results indicate that, for both sandstone and carbonate case studies, all three implemented metaheuristic algorithms are more efficient and reliable than the empirical correlation to predict VS . The results also demonstrate that in both sandstone and carbonate case studies, the performance of an artificial bee

    To investigate the radiological findings prognostic for the development of pancreatic adenocarcinoma in a cohort of patients with hepatocellular carcinoma, using multiphasic computed tomography (CT). A case-cohort study performed in a single university hospital. A database of patients who received hepatocellular carcinoma (HCC) treatment and trimonthly follow-up with four-phase dynamic CT was used (n = 1848). The cohort group was randomly extracted from the database (n = 103). The case group comprised nine patients from the database who developed pancreatic adenocarcinoma. The radiological findings were assessed during follow-up (average, 32 months). The incidence of pancreatic mass, inhomogeneous parenchyma, loss of fatty marbling and main pancreatic duct dilatation gradually increased from 4 to 13 months before the diagnosis of pancreatic adenocarcinoma. There was a significantly higher incidence of pancreatic mass, inhomogeneous parenchyma and loss of fatty marbling on CT at baseline (average, 34 months before diagnosis) in the case group compared with the cohort group (P values < 0.01) and those findings at baseline were revealed as prognostic factors for pancreatic carcinogenesis, respectively (log-rank test, P values < 0.001). Several radiological findings observed on multiphasic CT can assist in predicting pancreatic carcinogenesis well in advance. (orig.)

    In the present paper, one presents an approach to hazard identification and risks quantification concerning the use of retrievable BHA, of a casing drilling system, in 12 1/4 phase of an onshore well. The adopted approach can be subdivided as: execution of a hazard and operability study; prioritization of critical deviance; modeling of critical deviance by mean of event sequence diagram, fault tree and Bayesian network; modeling and simulation of a dynamic decision tree and experts' opinion analysis. As results, one has obtained: the time distribution to achieve the different ends modeled in the decision tree, i.e., sidetrack, or operation canceling, or success; the probabilities to achieve each modeled end and all recommendation to improve the success probability. The approach proved to be efficient in order that it presents significant results to support the decisions involving the casing drilling operations. (author)

    An estimated 27 million South Africans use indigenous medicines (Mander, 1997, Medicinal plant marketing and strategies for sustaining the plant supply in the Bushbuckridge area and Mpumalanga Province. Institute for Natural Resources, University of Natal. Pietermaritzburg, South Africa). Although herbal remedies are freely available in amayeza stores, or Xhosa chemists, for self-medication, little is known about the motivations of consumers. According to African belief systems, good health is holistic and extends to the person's social environment. The paper makes a distinction between traditional medicines which are used to enhance personal well-being generally and for cultural purposes, on the one hand, and medicines used to treat physical conditions only, on the other. Drawing on an eight-month study of Xhosa chemists in Eastern Cape Province, South Africa, in 1996, the paper identifies 90 medicines in stock which are used to enhance personal well-being. Just under one-third of all purchases were of medicines to enhance well-being. Remedies particularly popular included medicines believed to ward off evil spirits and bring good luck. The protection of infants with medicines which repel evil spirits is a common practice. Consumer behaviours indicate that the range of medicines available is increased by indigenisation of manufactured traditional medicines and cross-cultural borrowing. Case studies confirm that self- and infant medication with indigenous remedies augmented by indigenised medicines plays an important role in primary health care by allaying the fears and anxieties of everyday life within the Xhosa belief system. thereby promoting personal well-being.

    Association between wellness coaching and changes in health-related quality of life over 1 year and 2 years was assessed. Difference-in-differences analysis of covariance assessed association between coaching and change in 8-item short-form health survey (SF-8) summary scores. Ordered logistic models assessed coaching and change in SF-8 individual domain scores. This was a case-control study. Participants in at least one coaching program were more likely to have increases in social functioning after 1 year and less likely to have increases in role physical after 2 years. Participants in nutrition coaching had more positive change in mental component summary scores after 1 year. Participants in stress management had more negative change in mental component summary scores after 1 year and after 2 years and had more negative change in physical component summary scores after 2 years. Findings were mixed regarding association between coaching and change in health-related quality of life.

    Full Text Available Wax formation and deposition is one of the most common problems in oil producing wells. This problem occurs as a result of the reduction of the produced fluid temperature below the wax appearance temperature (range between 46°C and 50°C and the pour point temperature (range between 42°C and 44°C. In this study, two new methods for preventing wax formation were implemented on three oil wells in Libya, where the surface temperature is, normally, 29°C. In the first method, the gas was injected at a pressure of 83.3 bar and a temperature of 65°C (greater than the pour point temperature during the gas-lift operation. In the second method, wax inhibitors (Trichloroethylene-xylene (TEX, Ethylene copolymers, and Comb polymers were injected down the casings together with the gas. Field observations confirmed that by applying these techniques, the production string was kept clean and no wax was formed. The obtained results show that the wax formation could be prevented by both methods.

    Stress in office environments is a big concern, often leading to burn-out. New technologies are emerging, such as easily available sensors, contextual reasoning, and electronic coaching (e-coaching) apps. In the Smart Reasoning for Well-being at Home and at Work (SWELL) project, we explore the potential of using such new pervasive technologies to provide support for the self-management of well-being, with a focus on individuals' stress-coping. Ideally, these new pervasive systems should be grounded in existing work stress and intervention theory. However, there is a large diversity of theories and they hardly provide explicit directions for technology design. The aim of this paper is to present a comprehensive and concise framework that can be used to design pervasive technologies that support knowledge workers to decrease stress. Based on a literature study we identify concepts relevant to well-being at work and select different work stress models to find causes of work stress that can be addressed. From a technical perspective, we then describe how sensors can be used to infer stress and the context in which it appears, and use intervention theory to further specify interventions that can be provided by means of pervasive technology. The resulting general framework relates several relevant theories: we relate "engagement and burn-out" to "stress", and describe how relevant aspects can be quantified by means of sensors. We also outline underlying causes of work stress and how these can be addressed with interventions, in particular utilizing new technologies integrating behavioral change theory. Based upon this framework we were able to derive requirements for our case study, the pervasive SWELL system, and we implemented two prototypes. Small-scale user studies proved the value of the derived technology-supported interventions. The presented framework can be used to systematically develop theory-based technology-supported interventions to address work stress. In

  3. Neuroendocrine Tumor, Well Differentiated, of the Breast: A Relatively High-Grade Case in the Histological Subtype

    Shogo Tajima

    2013-01-01

    Full Text Available Primary neuroendocrine carcinoma of the breast is a rare entity, comprising <1% of breast carcinomas. Described here is the case of a 78-year-old woman who developed an invasive tumor in the left breast measuring 2.0 cm x 1.5 cm x 1.2 cm. The tumor was composed of only endocrine elements in the invasive part. It infiltrated in a nested fashion with no tubular formation. Intraductal components were present both inside and outside of the invasive portion. Almost all carcinoma cells consisting of invasive and intraductal parts were positive for synaptophysin and neuron-specific enolase. According to the World Health Organization classification 2012, this tumor was subclassified as neuroendocrine tumor, well-differentiated. Among the subgroup, this tumor was relatively high-grade because it was grade 3 tumor with a few mitotic figures. Vascular and lymphatic permeation and lymph node metastases were noted. In the lymph nodes, the morphology of the tumor was similar to the primary site. No distant metastasis and no relapse was seen for one year after surgery. The prognosis of neuroendocrine carcinomas is thought to be worse than invasive mammary carcinomas, not otherwise specified. Therefore, immunohistochemistry for neuroendocrine markers is important in the routine practice to prevent overlooking neuroendocrine carcinomas.

  4. Emergent nested systems a theory of understanding and influencing complex systems as well as case studies in urban systems

    CERN Document Server

    Walloth, Christian

    2016-01-01

    This book presents a theory as well as methods to understand and to purposively influence complex systems. It suggests a theory of complex systems as nested systems, i. e. systems that enclose other systems and that are simultaneously enclosed by even other systems. According to the theory presented, each enclosing system emerges through time from the generative activities of the systems they enclose. Systems are nested and often emerge unplanned, and every system of high dynamics is enclosed by a system of slower dynamics. An understanding of systems with faster dynamics, which are always guided by systems of slower dynamics, opens up not only new ways to understanding systems, but also to effectively influence them. The aim and subject of this book is to lay out these thoughts and explain their relevance to the purposive development of complex systems, which are exemplified in case studies from an urban system. The interested reader, who is not required to be familiar with system-theoretical concepts or wit...

    Full Text Available Globally, individuals seek happiness, but not everybody is happy.  Economic reasoning suggests that rising incomes with expansions in GDP enhance the quality of life and subjective well-being.  This paper examines the influences on individual happiness, using ordinal logistic regression and chi-square analyses.  Based on the findings of a small case study, the chi-square test indicated that a significant relationship exists between gender, education, ethnicity, children, marital status, employment relations, income and self-reported happiness. The study also found that, on average, happier people tended to be educated, married with children, and treated fairly at work.  But having too many children produced a decrement in individual happiness.   The ordinal regression results indicate that an individual’s education, gender, age distribution and work environment are influential in producing higher levels of happiness.  Entrepreneurs were found to have a significantly higher mean level of happiness than employees.  In the workplace, individuals who experienced personal growth and were able to contribute their ideas tended to be happier, relative to others who perceived themselves to be ‘restricted’.

    Splenic masses have a high prevalence and are more common than diffuse splenic enlargement in dogs. It was the aim of the present study to retrospectively describe clinical aspects and histopathologic characteristics of dogs with splenic masses. Records of patients with a histologically diagnosed splenic mass between January 2000 and March 2011 were reviewed. 249 dogs met the inclusion criteria and could be included in the study. Splenic masses were diagnosed histologically as non-malignant disease (n=117; 47%) and malignant splenic disease (n=132; 53%). Hemangiosarcoma was the most common histological diagnosis (n=97; 73.5%). Other malignant tumors included sarcoma (n=14), fibrohistiocytic nodules (n=9) as well as lymphoma, blastoma and adenocarcinoma. The non-malignant masses consisted of nodular hyperplasia (n=60), splenic hematoma (n=41), and splenitis (n=6). Dogs with hemoperitoneum had a higher frequency of splenic neoplasia. The results corroborate previous findings that hemangiosarcoma is the most frequent neoplasm of the canine spleen. However, in approximately half of the cases benign lesions were histologically diagnosed. It is essential that a frank discussion is held with owners regarding the prognosis associated with the treatment of dogs with a splenic mass associated with hemoperitoneum.

    The water supply system in Timisoara Municipality is insured with about 25-30 % of the water demand from wells. The underground water headed to the water treatment plant in order to ensure equal distribution and pressure to consumers. The treatment plants used are Urseni and Ronaţ, near Timisoara, in Timis County. In Timisoara groundwater represents an alternative source for water supply and complementary to the surface water source. The present paper presents a case study with proposal and solutions for rehabilitation /equipment /modernization/ automation of water drilling in order to ensure that the entire system can be monitored and controlled remotely through SCADA (Supervisory control and data acquisition) system. The data collected from the field are designed for online efficiency monitoring regarding the energy consumption and water flow intake, performance indicators such as specific energy consumption KW/m3 and also in order to create a hydraulically system of the operating area to track the behavior of aquifers in time regarding the quality and quantity aspects.

    Study on optimization of development well patterns is the core content of oilfield development and is a prerequisite for rational and effective development of oilfield. The study on well pattern optimization mainly includes types of well patterns and density of well patterns. This paper takes the Aer-3 fault block as an example. Firstly, models were built for diamond-shaped inverted 9-spot patterns, rectangular 5-spot patterns, square inverted 9-spot patterns and inverted 7-spot patterns under the same well pattern density to correlate the effect of different well patterns on development; secondly, comprehensive analysis was conducted to well pattern density in terms of economy and technology using such methods as oil reservoir engineering, numerical simulation, economic limits and economic rationality. Finally, the development mode of vertical well + horizontal well was presented according to the characteristics of oil reservoirs in some well blocks, which has realized efficient development of this fault block.

    In the late production stages, water production from natural gas wells may become a problem that may require abandoning the well, thus losing valuable productive assets. In a joint project of organisations of the Deutsche Wissenschaftliche Gesellschaft fuer Erdoel, Erdgas und Kohle, a status report was made in 2005, and best practice methods for dewatering natural gas wells were identified. This contribution presents some of the results: common methods for improved liquid unloading from natural gas wells, preconditions for their application, experience of the industries in this field, elements of the selection and planning process, and an outlook.

    Gunshot wounds are rare events in European countries, but stab and impalement injuries occur more frequently and are often spectacular. The aim of the study was to describe several types of penetrating abdomino-thoracic injuries as well as the appropriate surgical interventions, including complex wound management. The representative case series includes four patients with abdomino-thoracic penetrating trauma (two impalements and two stabbings), who were treated in a surgical university hospital (tertiary) centre during a 12-month period. 1. A man was impaled on a steel pipe, which entered the body above the right kidney and behind the liver through the mediastinum via the right thorax, passing the heart and aortic arch up to the left clavicle. The rod was removed via sternotomy and median laparotomy. Only the left subclavian vein required repair. Postoperatively, a residual lesion of the left brachial plexus caused temporary pneumonia. 2. A leg of a collapsing chair drilled into a woman's left foramen obturatorium and exited the body at the right anterior iliac spine. At a regional hospital, the chair leg was removed and the canal caused by gluteal penetration was excised. Exploratory laparotomy revealed peritonitis resulting from a perforated ileum. The injury was repaired with segmental resection and anastomosis. Postoperative right inguinal wound necrosis necessitated excision and vacuum-assisted closure sealing. The patient has residual paresthesia in her left leg resulting from a sacral plexus lesion. 3. During an altercation, a man was stabbed twice in the right thorax.

    Fuzzy analysis technique is proposed in this research for interpreting the combination of nuclear and electrical well logging data, which include natural gamma ray, density and neutron-porosity, while the electrical well logging include long and short normal. The main objective of this work is to describe, characterize and establish the lithology of the large extended basaltic areas in southern Syria. Kodana well logging measurements have been used and interpreted for testing and applying the proposed technique. The established lithological cross section shows the distribution and the identification of four kinds of basalt, which are hard massive basalt, hard basalt, pyroclastic basalt and the alteration basalt products, clay. The fuzzy analysis technique is successfully applied on the Kodana well logging data, and can be therefore utilized as a powerful tool for interpreting huge well logging data with higher number of variables required for lithological estimations. - Highlights: • Apply fuzzy analysis technique on the nuclear and electrical well logging data of Kodana well in Southern Syria. • Determine and differentiate between four kinds of basalt. • Establish the lithological section of the studied well.

  13. Cross-well slug testing in unconfined aquifers: A case study from the Sleepers River Watershed, Vermont

    Normally, slug test measurements are limited to the well in which the water level is perturbed. Consequently, it is often difficult to obtain reliable estimates of hydraulic properties, particularly if the aquifer is anisotropic or if there is a wellbore skin. In this investigation, we use partially penetrating stress and observation wells to evaluate specific storage, radial hydraulic conductivity and anisotropy of the aquifer, and the hydraulic conductivity of the borehole skin. The study site is located in the W9 subbasin of the Sleepers River Research Watershed, Vermont. At the site, ~3 m of saturated till are partially penetrated by a stress well located in the center of the unconfined aquifer and six observation wells located above, below, and at the depth of the stress well at radial distances of 1.2 and 2.4 m. The observation wells were shut in with inflatable packers. The semianalytical solution of Butler (1995) was used to conduct a sensitivity analysis and to interpret slug test results. The sensitivity analysis indicates that the response of the stress well is primarily sensitive to radial hydraulic conductivity, less sensitive to anisotropy and the conductivity of the borehole skin, and nearly insensitive to specific storage. In contrast, the responses of the observation wells are sensitive to all four parameters. Interpretation of the field data was facilitated by generating type curves in a manner analogous to the method of Cooper et al. (1967). Because the value of radial hydraulic conductivity is obtained from a match point, the number of unknowns is reduced to three. The estimated values of radial hydraulic conductivity and specific storage are comparable to those derived from the methods of Bouwer and Rice (1976) and Cooper et al. (1967). The values and skin conductivity, however, could not have been obtained without the use of observation wells.Normally, slug test measurements are limited to the well in which the water level is perturbed

    Full Text Available Studies worldwide point toward increased risk of mental health issues among immigrants. Immigrants’ ability to integrate the cultural identity of their new country has been found to be a key factor in their psychological well-being. Even though researchers agree on the crucial role of identity integration in immigrants’ well-being, the current literature has two main limitations: 1 researchers do not agree on the importance that should be allocated to each of the cultural identities, and 2 research has focused on bicultural individuals as opposed to multicultural individuals. The present paper proposes to study Canadians immigrants living in the province of Quebec who, because of the political and linguistic situation of the province, face the challenge of integrating two new cultural identities (Quebecer and Canadian to their original one. Specifically, cluster analysis was used to observe identity profiles that naturally emerge among 120 Canadian immigrants from the province of Quebec. Identity profiles were then compared on various indices of well-being to identify the optimal identity structure. In total, four identity profiles emerged, differing in their levels of identity coherence (i.e., similar levels of identification with each group and identification to either the original group or the Quebecers. ANOVA results confirmed that identity profiles differed in their average level of well-being. First, immigrants with coherent profiles displayed higher levels of well-being. Second, among incoherent profiles, the profile where identification to the original group is the highest showed the greatest well-being. Implications suggest that in order to maximize immigrants’ well-being, psychologists should focus on the coherence between cultural groups as well as identification to the original group.

    2017-03-01

    Full Text Available Carbon capture and sequestration technology is recognized as a successful approach taken to mitigate the amount of greenhouse gases released into the atmosphere. However, having a successful storage practice requires wise selection of suitable wells in depleted oil or gas fields to reduce the risk of leakage and contamination of subsurface resources. The aim of this paper is to present a guideline which can be followed to provide a better understanding of sophisticated wells chosen for injection and storage practices. Reviewing recent studies carried out on different aspects of geosequestration indicated that the fracture pressure of seals and borehole conditions such as cement-sheath integrity, distance from faults and fractures together with the depth of wells are important parameters, which should be part of the analysis for well selection in depleted reservoirs. A workflow was then designed covering these aspects and it was applied to a depleted gas field in Malaysia. The results obtained indicated that Well B in the field may have the potential of being a suitable conduit for injection. Although more studies are required to consider other aspects of well selections, it is recommended to employ the formation integrity analysis as part of the caprock assessment before making any decisions.

    2015-10-01

    Full Text Available This paper draws on Martha Nussbaum’s account of the nature of human well-being to explore the role of animals in formal education settings. Nussbaum equates well-being with human flourishing, and argues that people live well when engaged in essential functions that are particular capabilities, each a necessary but insufficient contributor to well-being. One of these capabilities is the ability to “to have concern for and live with other animals, plants and the environment.” Yet, this condition of well-being remains largely unexplored among in education. In recent years, the benefits of human-animal interaction in education settings has been researched and discussed in the social sciences, particularly  the use of dogs to aid reluctant readers in literacy development, and the use of therapy dogs in universities during final examination blocks. This paper presents findings of one particular research project of the effects of a unique, Canadian school-based cooperative education program, “Under One Woof,” in which students work with animals.  Based on interviews, students’ own stories of the impact of animal interaction – particularly in light of other challenges they faced academically and socially – appear to support other empirical accounts of positive effects of animals in education settings, and offer insight into the nature and effects of human-animal interaction as an element of well-being.

    Full Text Available Across the United States health systems are recognizing the urgency of addressing the social determinants of health in order to improve population health. Wellness trusts, modeled after financial trusts support primary health prevention in community settings, provide an innovative opportunity for better community-clinical linkages, collaboration, and impact. This study aimed to understand the necessary tenets for a wellness trust in Brooklyn, New York (USA and examined community interest and political will; administrative, financing, and leadership structures; and metrics and data sources to monitor and assess impact. We employed a multi-method design. Key informant interviews (KIIs (n = 15 were conducted from 7/2016 to 1/2017. A content analysis of grey literature was used to analyze community interest and political will (n = 38. Extant datasets, such as New York City Community District profiles, were reviewed, and a narrative review was used to assess cost-effectiveness of prevention interventions (n = 33. The KIIs and grey literature underwent thematic analysis. Findings indicated healthcare issues dominated the health agenda despite recognition of social determinants of health. Braided funding (discrete funds that are coordinated but tracked separately and blended funding (funds pooled from multiple sources tracked together are common funding mechanisms. Robust data systems exist to assess impact. Indicators should address social determinants, performance and impact, be measurable, geographically specific, and include communities. Wellness trusts should be sustainable, engage communities, foster collaboration, and have adequate capacity. The Collective Impact Framework, a mechanism to coordinate and maximize efforts, offers this organizational structure. Wellness trusts are promising mechanisms to advance population health.

  5. The science and politics of human well-being: a case study in cocreating indicators for Puget Sound restoration

    Directory of Open Access Journals (Sweden)

    2017-09-01

    Full Text Available Across scientific fields, there have been calls to improve the integration of scientific knowledge in policy making. Particularly since the publication of the Millennium Ecosystem Assessment, these calls increasingly refer to data on human well-being related to the natural environment. However, policy decisions involve selective uptake of information across communities with different preferences and decision-making processes. Additionally, researchers face the fact that there are important trade-offs in producing knowledge that is simultaneously credible, legitimate, socially relevant, and socially just. We present a study that developed human well-being indicators for Washington State's Puget Sound ecosystem recovery agency over 3 years. Stakeholders, decision makers, and social scientists were engaged in the identification, modification, and prioritization of well-being indicators that were adopted by the agency for tracking progress toward ecosystem recovery and strategic planning. After substantial literature review, interviews, workshops, and indicator ranking exercises, 15 indicators were broadly accepted and important to all audiences. Although the scientists, decision makers, and stakeholders used different criteria to identify and prioritize indicators, they all agreed that indicators associated with each of 6 broad domains (social, cultural, psychological, physical, economic, and governance were critical to assess the holistic concept of well-being related to ecosystem restoration. Decision makers preferred indicators that mirrored stakeholder preferences, whereas social scientists preferred only a subset. The Puget Sound indicator development process provides an example for identifying, selecting, and monitoring diverse concepts of well-being related to environmental restoration in a way that promotes recognition, participation, and a fair distribution of environmental benefits across the region.

    We investigate the influence of growth temperature, p -doping with bis-cyclopentadienyl magnesium (Cp{sub 2}Mg) and number N of multi-quantum wells on the surface morphology, the electrical and optical properties of InGaN-based solar cells grown by metal-organic vapour phase epitaxy. Atomic force microscopy measurements show no influence of multiple-quantum well number on the surface morphology, but a smoothing with the increase of the Cp{sub 2}Mg flow. Electrochemical capacitance-voltage profiling exhibits an increase of the N{sub a}-N{sub d} concentration when increasing the Cp{sub 2}Mg flow from 250 to 700 sccm. X-ray diffraction analysis and transmission electron microscopy measurements confirm completely strained quantum wells with similar superlattice period for N=5 to 30. Finally, first solar cells have been demonstrated with a maximum external quantum efficiency of 38% at 380 nm wavelength for N=30. (copyright 2012 WILEY-VCH Verlag GmbH and Co.

    Full Text Available The present study evaluates the chemical parameters (inorganic anions and metals of drinking water of twenty-four wells and the presence of Escherichia coli in ten selected wells located in two villages from Buzau and Prahova Counties, in Curvature Sub-Carpathians, Romania, a rural area frequently affected by flood events. Water samples were collected in July 2014. Concerntrations of fluorides, nitrites, chlorides and phosphates were below the maximum allowable concentrations (MACs for drinking water established by European legislation (Drinking Water Directive 98/83/CE in all the analysed samples. Concentration of nitrates exceeded MAC (50 mg L-1 in five samples, while concentration of sulphates exceeded MAC (250 mg L-1 in two samples. Among the analysed metals, Mn exceeded MAC (50 μg L-1 in two samples, while Cu, Pb, Zn, Fe, Na, Cd, Cr, Cu, Ni and As concentrations did not exceeded the corresponding MACs. E. coli (over 2000 UFC 100 mL-1 was found in six water samples. The results show that majority of the studied parameters were below the threshold limits, however in some of the studied wells the water was found to be contaminated both by some chemical pollutants and by E. coli, which prepresent a risk for local population health.

It has been found that in contrast to the Russians, the sphere of social and socio-economic relations is the least “happy” area in the representatives of the Armenian, Kazakh, Tatar ethnic groups. The “happiest” is the sphere of family relations in the samples of Armenian, Kazakh and Tatar youth. The significant differences have been revealed in the structure of the subjective well-being both on the emotional and cognitive levels. A downward trend of the index of the subjective well-being of the ethnic groups from the remote areas of the region has been registered. The applied aspect of the research problem can be implemented in the development of ethno-national policy programmes of the Saratov region.

    Highlights: ► The best performance of helical pump has been reached for a deep well. ► Very high potential of solar energy at Saudi Arabia. ► Performance of solar water pumping system for a deep well of 120 m. ► We get the best efficiency of helical pump for the head of 80 m. ► The best configuration of PV generator (24 panels) has been obtained. - Abstract: The photovoltaic water pumping systems (PVWPS) constitute a potential option to draw down water in the remote desert locations for domestic usage and livestock watering. However, the widespread of this technique requires accurate information and experiences in such system sizing and installation. The aim of this work is to determine an optimum photovoltaic (PV) array configuration, adequate to supply a DC Helical pump with an optimum energy amount, under the outdoor conditions of Madinah site. Four different PV array configurations have been tested (6S × 3P, 6S × 4P, 8S × 3P and 12S × 2P). The tests have been carried for a head of 80 m, under sunny daylight hours, in a real well at a farm in Madinah site. The best results have been obtained for two PV array configurations (6S × 4P) and (8S × 3P) which are suitable to provide the optimum energy. Powered by the selected PV array configurations, the helical pump (SQF2.5-2) delivered a maximum daily average volume of water needed (22 m 3 /day).

    2010-01-01

    The quality and the power of human activities affect the external environment in different ways that can be measured and evaluated by means of several approaches and indicators. While the scientific community has been publishing several proposals for sustainable development indicators, there is still no consensus regarding the best approach to the use of these indicators and their reliability to measure sustainability. It is important, therefore, to question the effectiveness of sustainable development indicators in an effort to continue in the search for sustainability. This paper compares the results obtained with emergy accounting with five global Sustainability Metrics (SMs) proposed in the literature to verify if metrics are communicating coherent and similar information to guide decision makers towards sustainable development. Results obtained using emergy indices are discussed with the aid of emergy ternary diagrams. Metrics are confronted with emergy results, and the degree of variability among them is analyzed using a correlation matrix created for the Mercosur nations. The contrast of results clearly shows that metrics arrive at different interpretations about the sustainability of the nations studied, but also that some metrics may be grouped and used more prudently. Mercosur is presented as a case study to highlight and explain the discrepancies and similarities among Sustainability Metrics, and to expose the extent of emergy accounting.

    Research Highlights: → We performed a numerical benchmark in the framework of an OECD experimental program of a pool fire in a well-confined compartment. → The benchmark involves 17 participants using 8 fire models, 3 CFD and 5 zone models. → We investigated the capabilities of validation metrics for a real large-scale fire. → Six quantities were compared during the whole fire duration. → It is important to consider more than one metric for the validation process. - Abstract: The objective of this work was to quantify comparisons between several computational results and measurements performed during a pool fire scenario in a well-confined compartment. This collaborative work was initiated under the framework of the OECD fire research program and involves the most frequently used fire models in the fire community, including field and zone models. The experimental scenario was conducted at the French Institut de Radioprotection et de Surete Nucleaire (IRSN) and deals with a full-scale liquid pool fire in a confined and mechanically ventilated compartment representative for nuclear plants. The practical use of different metric operators and their ability to report the capabilities of fire models are presented. The quantitative comparisons between measurements and numerical results obtained from 'open' calculations concern six important quantities from a safety viewpoint: gas temperature, oxygen concentration, wall temperature, total heat flux, compartment pressure and ventilation flow rate during the whole fire duration. The results indicate that it is important to use more than one metric for the validation process in order to get information on the uncertainties associated with different aspects of fire safety.

    2015-06-01

    Full Text Available Psychological research in culturally plural societies has traditionally been divided into two domains: acculturation and ethnic relations. Berry’s model of acculturation and psychological well-being is highly regarded and widely recognized as in the field. His two-dimensional model of acculturation is based upon the multicultural ideology where individuals and groups are given the opportunity to choose among various elements of ethnic and host cultures to form their own unique blends of identity and culture. The findings support the Berry’s proposal that acculturation is two-dimensional (ethnic/cultural and host society identification for acculturating immigrants. But the process of acculturation is different depending on the life domains being considered. Youngsters do not endorse both cultures to the same degree in all domains, which means acculturation preferences for Turkish youngsters between the ages of 12-15 are domain dependent. In terms of average point acculturation preferences, Turkish youth endorsed integration more than any other acculturation strategies. Significant correlation was found among self-esteem and separation acculturation attitude for reading books domain. Second significant correlation was found among self-esteem and margina¬lization acculturation attitude for work domain.

    The objective of this study is to identify individual mechanisms of change that result from engaging in an innovative participatory public art project for persons with significant behavioral health challenges. We present two case studies that examine how participatory public art promotes recovery and wellness. This research is part of a larger, multilevel comparative outcome trial on the impact of participatory public art on the health and well-being of adults in recovery from mental illness and addiction and on the distressed city neighborhoods in which they live. The case studies describe the unique ways in which participatory public art contributed to key recovery domains of growth in friendship, self-discovery, giving back, and hope. The two cases indicate that the development of a strengths-based sense of self through art was accompanied by a growth in personal social responsibility. The two cases also indicate that participatory public art may have a profound impact on the internalization of stigma. The findings support the value of participatory public art as a strategy for blending recovery and public health perspectives to promote both individual and community wellness.

    We report a novel case of a rare disease: spontaneous Creutzfeldt-Jakob disease in a patient with well-controlled HIV. We explore the relationship between spontaneous Creutzfeldt-Jakob disease and HIV. A 66-year-old man with long-standing, well-controlled HIV infection presented with 3 months of progressive, subacute neurocognitive decline. His symptoms included conceptual apraxia, apathy, memory impairment, and gait disturbance, and were initially attributed to depressive "pseudo-dementia." Unfortunately, the patient's symptoms rapidly progressed and he ultimately succumbed to his illness. Autopsy confirmed the clinical diagnosis of spontaneous Creutzfeldt-Jakob disease. This case highlights spontaneous Creutzfeldt-Jakob disease as a rare terminal illness in the setting of well-controlled chronic HIV. To our knowledge, this is the first report of a patient with chronic and previously well-controlled HIV infection dying from a prion disease. Despite the very different epidemiology and pathophysiology of HIV and spontaneous Creutzfeldt-Jakob disease, this case does raise questions of whether certain host genetic factors could predispose to both conditions, albeit currently, there is no clear causal link between HIV and spontaneous Creutzfeldt-Jakob disease.

    Spindle cell carcinoma (SpCC), which predominantly arises in the oral, pharyngeal and laryngeal mucosal tissues, is composed of a mixture of squamous and sarcomatoid components. The present study describes the case of a 62-year-old woman with SpCC recurrence 4 years after an initial surgery to remove a well-differentiated primary squamous cell carcinoma (SCC) of the tongue. The recurrent tumor was spherical and located deep within the tongue tissue, which differs from the typical manifestation of ulcerated masses of the mucosa. The majority of cases of recurrence involving SpCC are associated with radiotherapeutic treatment of the primary malignancy; however, the patient in the present study had not received postoperative radiotherapy for SCC. Furthermore, the recurrent tumor in the present case exhibited marked anaplasia and sarcomatoid features, and the absence of SCC elements upon biopsy rendered histological diagnosis difficult. In summary, the present findings suggest that immunohistochemical examination and identification of SCC components are essential for ensuring the accuracy of the histological diagnosis of recurrent SpCC following a primary epithelial malignancy.

    Students with profound intellectual disabilities disorders (IDDs) have the right to participate in educational opportunities that recognize their unique resources and needs, as do all children. Because of their specific communication challenges, positive relationships with attentive communication partners are critical for success. In fact, the power of positive relationships in schools is recognized to be connected to student well-being more broadly. This article examines the case of one young man with profound IDD and his relationship with his music therapist using a duo-ethnographic informed paradigmatic case study. Video analysis based on multi-voice perspectives is used to generate hermeneutic phenomenological findings to closely examine the relationship between a young man with profound IDD and a music therapist. The voices of four allied health researchers were also gathered to inform the authors’ construction of an informed commentary on the phenomenon. The results suggest that the essence lay in a combination of attentive, responsive and creative being with the other person over time. Four principles of musical engagement were identified in the video footage as critical to the meaningful relationships through music: the music therapist listens; the music therapist takes responsibility for structure; spontaneous initiation is sought from the young person; and the relationship is built over time. These concepts are contextualized within a discussion of student well-being that is underpinned by positive relationships and leads to students achieving their full potential within diverse school contexts.

    Full Text Available Despite being one of the most frequent soft-tissue sarcomas, well-differentiated liposarcoma has never been reported near the spine. The authors present the case of a 67-year-old man with progressive history of back pain. Physical examination revealed a mass located within the right paravertebral muscles. MR and CT imaging showed a heavily ossified central mass surrounded by a peripheral fatty component. No connection with the underlying bone was detected on imagery and during surgery. After surgical resection, histopathological examination revealed a tumor harboring combined features of well-differentiated liposarcoma and low-grade osteosarcoma. Tumor cells displayed overexpression of MDM2, CDK4, and P16 by immunohistochemistry and CGH revealed amplification of 12q13-15 as the only genetic imbalance. MDM2 FISH analysis was performed but was inconclusive. The pathological, immunohistochemical, and genetic features, the differential diagnoses, and the therapeutic management of this unusual tumor are discussed. No complementary treatment was performed initially. Following first treatment, two recurrences occurred 6 and 9 years later, both displaying histological features similar to the first occurrence. Radiotherapy was started after the second recurrence. Follow-up shows no evidence of disease 11 years after initial diagnosis. This case was unusual due to the paravertebral location of the tumor and its divergent differentiation.

    Six wells and a drilling rig, setting company, national and world records such as deepest well, longest horizontal well, and record setting completion technology are described. Steam assisted gravity drainage (SAGD) is mainly responsible for these outstanding successes. Discovered more than 20 years ago by a then Imperial oil scientist (Dr. Roger Butler) SAGD promises recovery rates of about 70 per cent for the right reservoir; more than twice the 25 to 30 per cent recovery rate with cyclic stimulation at Cold Lake and an average recovery rate of about 28 per cent for all Alberta light, medium and heavy oil wells. The seven facilities discussed in this article are : (1) Alberta Energy Company's Forest Hill oil sands project near Cold Lake, the first commercial SAGD operation where well pairs are producing 1,200-1,500 bbls per day; (2) Talisman Energy's Lovett River wells, which hold the company's depth record for a horizontal well in the Alberta Foothills; (3) Also owned by Talisman Energy in the Buchan Field in the North Sea, this well is famous for the fact that it was drilled with coiled tubing from a floating production vessel; : (4) in the Peco Field, south of Edson Alberta and owned by EOG Resources Canada, this well holds the Canadian offshore record for a single run using rotary steerable technology; (5) Burlington Resources Canada 's Burlington HZ Hinton 2-34-52-26 W5M well is best known for its record setting extended reach open hole coiled tubing job; (6) another Burlington Resources well holds the record for the deepest one-trip whipstock system ever run in Canada and milled successfully in one trip; and (7) a drilling rig in the Wabasca-Brintnell area of northern Alberta, owned by Canadian Natural Resources Limited, holds the record for drilling the largest number of horizontal holes in one year with the same rig.

    The purpose of this case report was to describe the outcomes following the use of kinesthetic feedback as a primary intervention strategy for gait training. The plan of care for this 22-year-old female addressed the patient's social wellness goal of "walking more normally," using motor learning principles. At initial examination, the patient demonstrated asymmetries for gait kinematics between the left and right lower extremity (analyzed using video motion analysis), pattern of force distribution at the foot, and activation of specific lower extremity muscles (as measured by surface electromyography). Interventions for this patient consisted of neuromuscular and body awareness training, with an emphasis on kinesthetic feedback. Weekly sessions lasted 30-60 minutes over 4 weeks. The patient was prescribed a home program of walking 30-60 minutes three times/week at a comfortable pace while concentrating on gait correction through kinesthetic awareness of specific deviations. Following intervention, the patient's gait improved across all objective measures. She reported receiving positive comments from others regarding improved gait and a twofold increase in her walking confidence. Outcomes support a broadened scope of practice that incorporates previously unreported integration of a patient's social wellness goals into patient management.

  13. Models of hemapoietic changes on the basis of systematically collected case histories of radiation accident victims as well as pathophysiologically evaluated patients after chronic radiation exposure

    The research project ''Models of Hematopoietic Changes on the Basis of Systematically Collected Case Histories of Radiation Accident Victims as well as Pathophysiologically Evaluated Patients after Chronic Radiation Exposure'' required the investigation of four major research problem areas. First of all, biomathematical models were improved or newly developed allowing the simulation of the radiation induced response patterns of granulocytes, lymphocytes and blood platelets. The compartment model approach allowed the establishment of the correlation of such blood cell changes to the extent of damage at the level of hemopoietic stem cells distributed throughout the skeleton. The utilization of neural-network techniques resulted in a ''synergetic'' model that enables the medical doctor - using blood cell changes within the first 5-6 days after exposure - to predict the further course of illness and to allow a rational approach to clinical management. Secondly, available information on the clinical consequences of radiation exposure on more than 800 accident victims enabled the team to develop an entirely new concept to recognize and treat such persons. For this approach the biomathematical models were used to identify ''response categories'' (rather than dosimetrically defined ''exposure categories'') with an organ specific grading code of the severity of radiation-induced damage. This grading allowed the semi-quantitative damage assessment of the hemopoiesis, the neurovascular system, the gastrointestinal as well as the cutaneous system. It forms the basis for a ''weighted'' prognosis and for the logistics of radiation accident medical management. In the third project domain, models were developed to understand pathophysiological mechanisms of biological consequences of chronic radiation in human beings (former USSR) as well as in a preclinical dog study (USA). From a large group of patients with the diagnosis of ''Chronic Radiation Sickness'' more than 80 were

    The apparatus relates in particular to a well-treating process in which an aqueous acid solution having a pH of < 2 is injected into a subterranean reservoir in a manner such that materials that contain ferric ions are present in the acid and, as the acid reacts within the reservoir and attains a pH exceeding 3, tend to be precipitated as ferric ion-containing solid materials that may plug the pores of the reservoir. Such a precipitation is prevented by dissolving in the acid solution an amount of 5-sulfosalicylic acid which is at least sufficient to sequester significant proportions of ferric ions when the pH of the acid is from 0.5 to 3 but is less than enough to cause a significant salting-out of solid materials, and an amount of citric acid which is at least sufficient to sequester significant proportions of ferric ions when the pH of the acid is from 3 to 6 but is less than enough to precipitate a significant amount of calcium citrate. The amount of the 5-sulfosalicylic acid may be from 0.01 to 0.05 moles/l and the amount of citric acid is from 0.001 to 0.009 moles/l. 11 claims.

    Previous research suggests that singing in a choir as an older adult is associated with better quality of life (QOL). However, the degree to which sociodemographic variables and level of engagement in hobbies contribute to this relationship is largely unknown. The aim of the study was to compare quality of life (QOL) of older adult choir singers with a matched sample of older adults from the general population in Finland, taking into consideration sociodemographic, satisfaction with health, and level of engagement in hobbies (active, inactive). Case-control methods were used to match a sample of 109 older adult singers with a sample of 307 older adults from the general population. Tobit regression analysis with sociodemographic covariates was used to explore observed group differences in QOL as measured by two WHOQOL-Bref domains (psychological and physical). Probit regression analysis was used to examine the effect of sociodemographic variables and engagement in hobbies and on overall QOL and satisfaction with health. As expected, sociodemographic variables were strongly associated with physical and psychological QOL. After controlling for sociodemographic variables, the older choir singers reported significantly higher ratings on physical QOL, but not psychological QOL, compared to matched controls. Additional adjustment for satisfaction for health attenuated the results. When considering level of engagement in hobbies, older adult choir singers reported significantly higher overall QOL and satisfaction with health when compared to either controls who were either actively engaged in hobbies or not active in hobbies. These results suggest that singing in a choir as an older adult may promote well-being, even after accounting for sociodemographic and level of engagement in hobbies.

We report a case of a 63-year-old woman with a symptomatic metastatic NET of the ileum. Complete symptomatic response was achieved after 1 month of treatment with SSAs. In addition, there was an objective response in the liver, with the disappearance of secondary lesions noted on computed tomography scan after 3 months of octreotide treatment. Our experience suggests that SSAs could be useful for downstaging and/or downsizing well-differentiated NETs, and they could allow surgery to be performed. Such presurgery therapy could be a promising tool in the management of patients with initially inoperable NETs.

    Boley, Harold; Osmun, Taylor Michael; Craig, Benjamin Larry

    An interoperation study, WellnessRules, is described, where rules about wellness opportunities are created by participants in rule languages such as Prolog and N3, and translated within a wellness community using RuleML/XML. The wellness rules are centered around participants, as profiles, encoding knowledge about their activities conditional on the season, the time-of-day, the weather, etc. This distributed knowledge base extends FOAF profiles with a vocabulary and rules about wellness group networking. The communication between participants is organized through Rule Responder, permitting wellness-profile translation and distributed querying across engines. WellnessRules interoperates between rules and queries in the relational (Datalog) paradigm of the pure-Prolog subset of POSL and in the frame (F-logic) paradigm of N3. An evaluation of Rule Responder instantiated for WellnessRules revealed acceptable Web response times.

    Well vulnerability assessment is essential for groundwater source protection. A quantitative approach to assess well vulnerability in a well capture zone is presented, based on forward solute transport modeling. This method was applied to three groundwater source areas (Jiuzhan, Hadawan and Songyuanhada) in Jilin City, northeast China. The ratio of the maximum contaminant concentration at the well to the released concentration at the contamination source ( c max/ c 0) was determined as the well vulnerability indicator. The results indicated that well vulnerability was higher close to the pumping well. The well vulnerability in each groundwater source area was low. Compared with the other two source areas, the cone of depression at Jiuzhan resulted in higher spatial variability of c max/ c 0 and lower minimum c max/ c 0 by three orders of magnitude. Furthermore, a sensitivity analysis indicated that the denitrification rate in the aquifer was the most sensitive with respect to well vulnerability. A process to derive a NO3-N concentration at the pumping well is presented, based on determining the maximum nitrate loading limit to satisfy China's drinking-water quality standards. Finally, the advantages, disadvantages and prospects for improving the precision of this well vulnerability assessment approach are discussed.

    Methods and apparatus are provided for measuring the acoustically modulated electronic properties of geological formations and cement layers adjacent to cased boreholes. Current is passed from an electrode in electrical contact with the interior of the borehole casing to an electrode on the surface of the earth. Voltage measuring electrodes in electrical contact with the interior of the casing measure the voltage at various points thereon. The voltage differences between discrete pairs of the voltage measuring electrodes provide a measurement of the leakage current conducted into formation in the vicinity of those electrodes. Simultaneously subjecting the casing and formation to an acoustic source acoustically modulates the leakage current measured thereby providing a measure of the acoustically modulated electronic properties of the adjacent formation. Similarly, methods and apparatus are also described which measure the leakage current into formation while simultaneously subjecting the casing to an applied magnetic field which therefore allows measurement of the magnetically modulated electronic properties of the casing and the adjacent formation. 9 figures.

    Presently, there is increased in research on job strain and the effects of religiosity on employee well-being. Despite increased recognition of religiosity as a moderator of well-being, limited research has focused on Islamic perspective of moderating job strain. This study examines the moderating effects of Islamic personal religiosity on the relationship between job strain and employee well-being in Malaysian universities. One hundred and seventeen (117) Muslim academic and administrative staff from four public universities were sampled. Data were collected via questionnaires, and our findings show that the effect of job strain on well-being is significant for employees and that personal religiosity of employees contributed to alleviating job strain and enhancing well-being. Thus, the study concludes that Islamic personal religiosity moderates the relationship between job strain and employee well-being.

    Full Text Available In the present study, MODFLOW-MT3D groundwater model was employed to perform numerical experimentation to develop design and operational parameters for SW (Skimming Wells based on hydrogeology and groundwater salinity conditions of Chaj Doab, Punjab, Pakistan. Numerical experimentation resulted in: (i a 1-strainer SW with discharge of 14 l/s (litres per second and penetration of 30% resulted in more saltwater upconing at 8 hours/day well operation compared to that occurred at 4 hours/day operation; (ii a 1-strainer well with penetration of 30% and operation of 8 hours/day caused higher saltwater upconing at 14 l/s discharge compared to that at 9 l/s discharge; (iii a 4-strainer well with penetration of 30% and operation of 8 hours/day also caused more saltwater upconing at 14 l/s well discharge compared to that at 9 l/s discharge. Similar trend was found for a 8- strainer well; and (iv 1- or 4- or 8-strainer well with 30-60% penetration, 9-14 l/s discharge and 4-8 hours/day operation could provide pumped groundwater of salinity less than 1000 ppm. Considering hydro-chemical performance and costs of wells, a 4-strainer well with 30% penetration, 9- 14 l/s discharge and 4-8 hours/day operation is recommended to skim groundwater of salinity less than 1000 ppm in Chaj Doab of Punjab, Pakistan

    Low-carbohydrate, high-fat and ketogenic diets are increasingly adopted by athletes for body composition and sports performance enhancements. However, as yet, there is no consensus on their efficacy in improving performance. There is also no comprehensive literature on athletes' experiences while undertaking this diet. The purpose of this pilot work was two-fold: i. to examine the effects of a non-calorie controlled ketogenic diet on body composition and performance outcomes of endurance athletes, and ii. to evaluate the athletes' experiences of the ketogenic diet during the 10-week intervention. Using a case study design, five New Zealand endurance athletes (4 females, 1 male) underwent a 10-week ketogenic dietary intervention. Body composition (sum of 8 skinfolds), performance indicators (time to exhaustion, VO 2 max, peak power and ventilatory threshold), and gas exchange thresholds were measured at baseline and at 10 weeks. Mean change scores were calculated, and analysed using t-tests; Cohen's effect sizes and 90% confidence limits were applied to quantify change. Individual interviews conducted at 5 weeks and a focus group at 10 weeks assessed athletes' ketogenic diet experiences. Data was transcribed and analysed using thematic analysis. All athletes increased their ability to utilise fat as a fuel source, including at higher exercise intensities. Mean body weight was reduced by 4 kg ± SD 3.1 ( p  = 0.046; effect size (ES):0.62), and sum of 8 skinfolds by 25.9 mm ± SD 6.9; ES: 1.27; p  = 0.001). Mean time to exhaustion dropped by ~2 min (±SD 0.7; p  = 0.004; ES: 0.53). Other performance outcomes showed mean reductions, with some increases or unchanged results in two individuals (VO2 Max: -1.69 ml.kg.min ± SD 3.4 ( p  = 0.63); peak power: -18 W ± SD 16.4 ( p  = 0.07), and VT2: -6 W ± SD 44.5 ( p  = 0.77). Athletes reported experiencing reduced energy levels initially, followed by a return of high levels thereafter

  7. Characteristic groundwater level regimes in the capture zones of radial collector wells and importance of identification (Case study of Belgrade Groundwater Source

    Full Text Available Assessment of the operating modes of radial collector wells reveals that the pumping levels in the well caissons are very low relative to the depth/elevation of the laterals, which is a common occurrence at Belgrade Groundwater Source. As a result, well discharge capacities vary over a broad range and groundwater levels in the capture zones differ even when the rate of discharge is the same. Five characteristic groundwater level regimes are identified and their origin is analyzed using representative wells as examples. The scope and type of background information needed to identify the groundwater level regime are presented and an interpretation approach is proposed for preliminary assessment of the aquifer potential at the well site for providing the needed amount of groundwater.

    Successful completion of the sub-horizontal dual-lateral well, K14-FB 102, to optimize production capacity and reservoir drainage in an offshore gas play in the Dutch sector of the North Sea is described. The two 5-7/8 inch horizontal production intervals were drilled and completed using a rheologically engineered, minimal solids, non-damaging sodium formate brine- based fluid designed as a drill-in fluid for reservoir intervals. The completion was made possible by the selection of the appropriate reservoir drill-in and completion fluid, appropriate level of contingency planning and a fully integrated team approach and custom-made well solution. Inflow performance has matched the performance of cemented and high-performance wells at a much lower cost. It was found that openhole reservoir completion techniques offer relatively inexpensive `fit-for-purpose` well solutions for low permeability sandstone in this region of the North Sea.3 refs., 6 tabs., 7 figs.

  9. Key technology for treating slack coal blockage in CBM recovery: A case study from multi-lateral horizontal wells in the Qinshui Basin

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available Due to the nature of coal bed, slack coal production is inevitable in gas recovery sby water drainage. When coalbed methane (CBM wells are reentered after low energy exploitation and shut-in, the negative effect of slack coal production on productivity of CBM is irreversible. In this paper, the CBM occurrence characteristics and multi-lateral horizontal well trajectory in the Qinshui Basin, Shanxi Province, were analyzed. In the multi-lateral horizontal wells, the expected gas production rate could not be reached and the production rate after shut-in maintenance could not restore to the level before shut-in. The reason for these issues is that migration pathways in the reservoirs are blocked by slack coal deposits, while formation water and slack coal deposit accumulated at the troughs of horizontal sections enlarge the resistance for gas to flow into the bottom hole. Furthermore, three key technologies to deal with slack coal blockage were proposed. Firstly, CBM horizontal well trajectory should follow the principle of keeping the wellbores smooth and updip instead of being “wavy”, on the premise of guaranteeing CBM drilling rate. Secondly, the cavities of production wells, as an important part of multi-lateral horizontal wells, are capable of settling sand, and can be used for gas–liquid–solid separation. And thirdly, a tree-like horizontal well with its main hole set on stable seam top or floor, provides a stable well flushing passage for coal powder. This research provides a useful attempt in solving the problem of slack coal production in gas recovery by water drainage.

    We examined whether children cared for by stressed caregivers show lower socio-emotional well-being and more stress, compared with children cared for by less stressed caregivers. Perceived stress and cortisol levels of professional caregivers (n = 44), and associations with children's (n = 44) well-being and cortisol levels in home-based child care were examined. Caregiver perceived stress and cortisol levels were related to children's well-being but not to children's cortisol levels. Children's social fearfulness acted as a moderator between caregivers' mean ratio of diurnal change in cortisol and children's well-being. When caregiver cortisol levels decreased, more fearful children were reported higher on well-being than less fearful peers. In contrast, when caregiver cortisol levels increased, more fearful children were reported lower on well-being. The findings point to differential susceptibility. Child care organizations and parents need to notice that a non-stressful child care environment is in particular important for children with a difficult temperament. © 2010 Blackwell Publishing Ltd.

    Full Text Available For the sake of figuring out the influential mechanisms of structural characteristics on the productivity of shale gas wells, the structural characteristics of the Jiaoshiba Block in the Fuling shale gasfield, Sichuan Basin, were analyzed. Then, based on well test data of more than 190 horizontal wells, the effects of structures on shale gas well productivity were discussed systematically, and the main structural factors of different structural units in the Jiaoshiba Block that influence the productivity of shale gas wells were clarified. The following results were obtained. First, the structural units in the Jiaoshiba Block were obviously different in structural characteristics and their deformation strength is different. Second, the influence of structural characteristics on shale gas well productivity is directly manifested in gas-bearing property and fracturing effect. The stronger the structural deformation and the more developed the large faults and natural fractures, the more easily shale gas escapes and the poorer the gas bearing property will be, and vice versa. Third, The stronger the structural deformation, the more developed the fractures, the greater the burial depth and the higher the compressive stress of negative structures, the worse the fracturing effect will be, and vice versa. And fourth, Tectonics is the key factor controlling the difference of shale gas productivity between different structural units in the Jiaoshiba Block, but the main structural factors influencing the productivity are different in different structural units.

    2013-04-01

    Full Text Available In this paper, a novel hybrid approach composed of adaptive neuro-fuzzy inference system (ANFIS and imperialist competitive algorithm is proposed. The imperialist competitive algorithm (ICA is used in this methodology to determine the most suitable initial membership functions of the ANFIS. The proposed model combines the global search ability of ICA with local search ability of gradient descent method. To illustrate the suitability and capability of the proposed model, this model is applied to predict oil flow rate of the wells utilizing data set of 31 wells in one of the northern Persian Gulf oil fields of Iran. The data set collected in a three month period for each well from Dec. 2002 to Nov. 2010. For the sake of performance evaluation, the results of the proposed model are compared with the conventional ANFIS model. The results show that the significant improvements are achievable using the proposed model in comparison with the results obtained by conventional ANFIS.

    Women with celiac disease (CD) living on a gluten-free diet (GFD) show a lower health-related quality of life and report a higher rate of gastrointestinal (GI) symptoms than men with CD. Uncertainty exists as to whether GI symptoms may explain the poorer treatment outcome of women with CD. This study was designed to explore relationships of GI symptoms and psychological well-being in men and women with long-standing CD. Patients with CD (n = 108; 59% women), aged 45-64 years, treated with a GFD for at least 8 years were evaluated by the Gastrointestinal Symptom Rating Scale and the Psychological General Well-Being index. The results show that women with a high rate of GI symptoms have no lower level of psychological well-being than corresponding men with CD and that women with CD with reduced psychological well-being have no more GI symptoms than corresponding men. Our results fail to support the notion that the reduced subjective health in CD is explained by GI symptoms. They may be secondary to perceived difficulties in managing everyday life, suggesting that launching a nurse-led follow-up may be helpful, as has been proven to be useful in other lifelong disorders.

    Full Text Available Abstract Introduction Resistance to thyroid hormone is a syndrome caused by thyroid hormone receptor β mutations, which are usually inherited in an autosomal-dominant pattern. Case presentation Our patient, a Japanese neonate boy, showed hyperthyroid symptoms at age two days. Although our patient was diagnosed as having resistance to thyroid hormone, his hyperthyroid symptoms continued for two weeks. Therefore, our patient was treated with methimazole and iodine for two weeks from birth, showing no side effects and no symptoms upon treatment. At age 70 days, an R243W mutation in thyroid hormone receptor β was detected in our patient; while absent in his mother, the mutation was present in his father, who never showed any symptoms. Conclusions To the best of our knowledge this is the first case report of a resistance to thyroid hormone in a neonate presenting with hyperthyroid symptoms born to a mother with Graves’ disease and treated with methimazole and iodine. These results suggest that methimazole and iodine may be a good short-term option for treatment.

    Full Text Available Contamination of groundwater resources by nitrate leaching under agricultural land is probably the most troublesome agriculture-related water contamination worldwide. Contaminated areas often show large spatial variability of nitrate concentration in wells. In this study, we tried to assess whether this spatial variability can be characterized on the basis of land use and standard agricultural practices. Deep soil sampling (10 m was used to calibrate vertical flow and nitrogen-transport numerical models of the unsaturated zone under different agricultural land uses. Vegetable fields (potato and strawberry and deciduous orchards (persimmon in the Sharon area overlying the coastal aquifer of Israel were examined. Average nitrate–nitrogen fluxes below vegetable fields were 210–290 kg ha−1 yr−1 and under deciduous orchards were 110–140 kg ha−1 yr−1. The output water and nitrate–nitrogen fluxes of the unsaturated-zone models were used as input data for a three-dimensional flow and nitrate-transport model in the aquifer under an area of 13.3 km2 of agricultural land. The area was subdivided into four agricultural land uses: vegetables, deciduous orchards, citrus orchards, and non-cultivated. Fluxes of water and nitrate–nitrogen below citrus orchards were taken from a previous study in the area. The groundwater flow model was calibrated to well heads by changing the hydraulic conductivity. The nitrate-transport model, which was fed by the above-mentioned models of the unsaturated zone, succeeded in reconstructing the average nitrate concentration in the wells. However, this transport model failed in calculating the high concentrations in the most contaminated wells and the large spatial variability of nitrate concentrations in the aquifer. To reconstruct the spatial variability and enable predictions, nitrate fluxes from the unsaturated zone were multiplied by local multipliers. This action was rationalized by the fact

    Observations of velocities in sediments containing gas hydrates show that the strength of sediments increases with hydrate saturation. Hence it is expected that the attenuation of these sediments will decrease with increasing hydrate saturation. However, sonic log measurements in the Mallik 2L-38 well and cross hole tomography measurements in the Mallik field have shown that attenuation increases with hydrate saturation. We studied a range of mechanisms by which increasing hydrate saturation could cause increased attenuation. We found that a difference in permeability between the host sediment and the newly formed hydrate can produce the observed effect. We modelled attenuation in terms of Biot and squirt flow mechanisms in composite media. We have used our model to predict observed attenuations in the Mallik 2L-38 well, Mackenzie Delta, Canada.

    Full Text Available Ngimbang Formation is known as one major source of hydrocarbon supply in the North Eastern Java Basin. Aged Mid-Eocene, Ngimbang is dominated by sedimentary clastic rocks mostly shale, shaly sandstone, and thick layers of limestone (CD Limestone, with thin layers of coal. Although, laboratory analyses show the Ngimbang Formation to be a relatively rich source-rocks, such data are typically too limited to regionally quantify the distribution of organic matter. To adequately sample the formation both horizontally and vertically on a basin–wide scale, large number of costly and time consuming laboratory analyses would be required. Such analyses are prone to errors from a number of sources, and core data are frequently not available at key locations. In this paper, the authors established four TOC (Total Organic Carbon Content logging calculation models; Passey, Schmoker-Hester, Meyer-Nederloff, and Decker/Density Model by considering the geology of Ngimbang. Well data along with its available core data was used to determine the most suitable model to be applied in the well AFA-1, as well as to compare the accuracy of these TOC model values. The result shows good correlation using Decker (TOC Model and Mallick-Raju (Ro- Vitrinite Reflectance Model. Two source rocks potential zones were detected by these log models.

    2011-01-01

    This study examined the associations between goal adjustment capacities, coping, and indicators of subjective well-being in two waves of data from individuals who provide care for a family member with mental illness. We hypothesized that goal adjustment capacities would predict higher levels of subjective well-being by facilitating coping with caregiving stress. Results showed that goal disengagement was associated with effective care-specific coping (e.g., less self-blame and substance use). Goal reengagement was also associated with effective care-specific coping (e.g., positive reframing), but at the same time it predicted the use of less useful strategies (e.g., venting and self-distraction). Moreover, goal disengagement predicted lower levels of caregiver burden and depressive symptoms, and buffered the longitudinal effect of caregiver burden on increases in depressive symptoms. Goal reengagement, by contrast, predicted higher levels of caregiver burden and purpose in life, and buffered the cross-sectional association between caregiver burden and depressive symptoms. Finally, effective (and less useful) care-specific coping statistically explained the adaptive (and maladaptive) effects of goal adjustment capacities on participants’ well-being. PMID:21381855

    Rate of penetration (ROP) is one of the key indicators of drilling operation performance. The estimation of ROP in drilling engineering is very important in terms of more accurate assessment of drilling time which affects operation costs. Hence, estimation of a ROP model using operational and environmental parameters is crucial. For this purpose, firstly physical and mechanical properties of rock were derived from well logs. Correlation between the pair data were determined to find influential parameters on ROP. A new ROP model has been developed in one of the Azadegan oil field wells in southwest of Iran. The model has been simulated using Multiple Nonlinear Regression (MNR) and Artificial Neural Network (ANN). By adding the rock properties, the estimation of the models were precisely improved. The results of simulation using MNR and ANN methods showed correlation coefficients of 0.62 and 0.87, respectively. It was concluded that the performance of ANN model in ROP prediction is fairly better than MNR method.

    Myofibroma is a neoplasia of myofibroblasts that can be solitary or multiple and it is found most commonly in the head & neck region including scalp, forehead, parotid region and oral cavity. In the eyelid it is rarely reported. It has a benign course in the solitary form and fatal in its multiple form. A 4 month male infant referred to Farabi hospital -the referral center for eye diseases- with a 2 month history of a mass in his eyelid with gradual enlargement with no other complaints. The only abnormal physical finding was a 2.5 cm mass in the eyelid. This mass was excised and sent to the hospital pathology laboratory. When confronting a spindle cell lesion with a nodular or multinodular growth pattern which appears biphasic due to alteration of light and dark staining areas, the surgical pathologist should think to the possibility of myofibroma. Its pattern of growth and architecture rules out the other differential diagnoses like nodular fasciitis, fibrous histiocytoma, infantile fibromatosis, and peripheral primitive neuroectodermal tumor, mesenchymal chondrosarcoma, malignant hemangiopericytoma, juvenile fibrosarcoma and poorly differentiated synovial sarcoma. In difficult cases immunohistochemical staining is helpful that is Vimentin & Actin positivity & Desmin, CK, EMA & S100 negativity.

    Here we report a case in which a locally advanced ascending colon cancer was successfully treated with anti-EGFR immunotherapy combined with chemotherapy and curative resection, and recurrent cancer was treated with the same chemotherapy. A 71-year-old man was diagnosed with ascending colon cancer in our department. No distant metastasis was observed, but curative resection was considered impossible because of extensive local cancer invasion. Because a genetic analysis revealed the presence of the wild-type KRAS gene, 6 courses of mFOLFOX6 plus cetuximab were administered. A cPR was obtained and curative resection was performed. The final diagnosis was ypT3N1M0, ypStage III a colon cancer, and chemotherapy improved the cancer stage to Grade 1b. Six courses of FOLFOX6 were then administered, followed by observation. After 2 years 6 months, a tumor of approximately 5 cm in size was noted in the right buttock using surveillance CT and was diagnosed as recurrent colon cancer. We considered further curative resection difficult and therefore 6 courses of mFOLFOX6 plus panitumumab were administered, a cPR was obtained, and right hip tumor extirpation surgery was performed. These results suggest that chemotherapy combined with anti-EGFR antibody immunotherapy is effective in treating recurrent colon cancer.

    The purpose of the study was to evaluate the progression of glaucomatous field damage in patients with stable primary open angle glaucoma after an attack of myocardial infarction. In this case control study, 62 open angle glaucoma patients were selected and regularly followed up. Among 62 patients, 9 had an attack of myocardial infarction. The intra-ocular pressure and visual field progression of both the groups (myocardial infarction versus no myocardial infarction) were analysed. Three (33.3%) out of 9 patients who had suffered from myocardial infarction showed progressive visual field loss whereas only 9 (16.9%) out of 53 patients who did not suffer from myocardial infarction, showed progressive field changes. Both the groups had stable target intra-ocular pressure between 14 and 16 mm Hg. Myocardial infarction may adversely influence the progression of primary open angle glaucoma which is suspected to result from ischaemia induced neuronal loss and only control of intraocular pressure is not the only solution. We have to look for other drugs that prevents ischaemia induced neuronal damage.

    Full Text Available Myofibroma is a neoplasia of myofibroblasts that can be solitary or multiple and it is found most commonly in the head & neck region including scalp, forehead, parotid region and oral cavity. In the eyelid it is rarely reported. It has a benign course in the solitary form and fatal in its multiple form.

    Full Text Available This study explored the effectiveness of storytelling in supporting children with unusual physical traits. Participants were forty-eight children, aged 9 – 12 who, due to various eye diseases, wear eyeglasses. They completed various standardized self-report measures, both before and after participation, in one of the six intervention groups. The measures assessed shyness and social anxiety symptoms, loneliness and social dissatisfaction, perception of negative evaluation, satisfaction with one’s appearance, and anxiety regarding physical appearance. The intervention consisted of six 90-min group sessions and included both individual and group activities. The results lend support to the hypothesis that storytelling can significantly contribute to the emotional well-being of children, with a distinct physical appearance.

    Nonmonotonic plasma potential structures are a common feature of many double layers and sheaths. Steady state plasma potential wells separating regions having different plasma potentials are often found in laboratory experiments. In order to exist, such structures all must find a solution to a common problem. Ions created by charge exchange or ionization in the region of the potential well are electrostatically confined and tend to accumulate and fill up the potential well. The increase in positive charge should eliminate the well. Nevertheless, steady state structures are found in which the wells do not fill up. This means that it is important to take into account processes which 'pump' ions from the well. As examples of ion pumping of plasma wells, potential dips in front of a positively biased electro collecting anode in a relatively cold, low density multidipole plasma is considered. Pumping is provided by ion leaks from the edges of the potential dip or by oscillating the applied potential. In the former case the two dimensional character of the problem is shown to be important.

    Exploration on reservoir of glutenite segment in steep slope zone of half graben-like basin is one of the hot spot targets at present and in the future for new reservoirs; And the study of sediment character of sandy-conglomerate bodies is the keystone and also the difficult problem. Taking Tuo-147-well area in north zone of Dongying depression as an example, the micro-canal sedimentation was researched. The result shows that many micro-canals exist at the end of slope grain-flow in steep slope zone of half graben-like basin; The micro-canals grow at the end of subaqueous grain-flow deposited bodies of 3rd member of the Shahejie formation. The main condition of micro-canal formation is the slope angle less than 18° and a long suitable sedimentary slope. These micro-canals may communicate the reservoir of glutenite segment in steep slope zone and the hydrocarbon stratum as a bridge role. Therefore, it is significant in theory and practice for discovering a series of micro-canals at the end of slope grain-flow in steep slope zone of half graben-like basin.

  20. Oxidative stress induces mitochondrial dysfunction in a subset of autism lymphoblastoid cell lines in a well-matched case control cohort.

    Full Text Available There is increasing recognition that mitochondrial dysfunction is associated with the autism spectrum disorders. However, little attention has been given to the etiology of mitochondrial dysfunction or how mitochondrial abnormalities might interact with other physiological disturbances associated with autism, such as oxidative stress. In the current study we used respirometry to examine reserve capacity, a measure of the mitochondrial ability to respond to physiological stress, in lymphoblastoid cell lines (LCLs derived from children with autistic disorder (AD as well as age and gender-matched control LCLs. We demonstrate, for the first time, that LCLs derived from children with AD have an abnormal mitochondrial reserve capacity before and after exposure to increasingly higher concentrations of 2,3-dimethoxy-1,4-napthoquinone (DMNQ, an agent that increases intracellular reactive oxygen species (ROS. Specifically, the AD LCLs exhibit a higher reserve capacity at baseline and a sharper depletion of reserve capacity when ROS exposure is increased, as compared to control LCLs. Detailed investigation indicated that reserve capacity abnormalities seen in AD LCLs were the result of higher ATP-linked respiration and maximal respiratory capacity at baseline combined with a marked increase in proton leak respiration as ROS was increased. We further demonstrate that these reserve capacity abnormalities are driven by a subgroup of eight (32% of 25 AD LCLs. Additional investigation of this subgroup of AD LCLs with reserve capacity abnormalities revealed that it demonstrated a greater reliance on glycolysis and on uncoupling protein 2 to regulate oxidative stress at the inner mitochondria membrane. This study suggests that a significant subgroup of AD children may have alterations in mitochondrial function which could render them more vulnerable to a pro-oxidant microenvironment derived from intrinsic and extrinsic sources of ROS such as immune activation and

    Sludge bioleaching technology with Acidithiobacillus species has been commercially adopted for improving advanced dewatering of sludge in China since 2010. However, up to now, little information on bioleached dewatered sludge (BS) composting is available. Here, we report the changes of physicochemical and biological properties in BS composting and evaluate compost product quality compared to conventional dewatered sludge (CS) composting in an engineering scale composting facility. The results showed that the amount of bulking agents required in BS composting was only about 10% of CS composting to obtain optimum moisture content, reducing about 700 kg bulking agents per ton fresh sludge. pH of BS composting mixture was slightly lower consistently by about 0.2-0.3 pH units than that in CS mixture in the first 30 days. Organic matter biodegradation in BS system mainly occurred in the first 9 days of composting. In spite of higher content of NH4(+)-N was found in BS mixture in related to CS mixture; unexpectedly the cumulative ammonia volatilization in the former was only 51% of the latter, indicating that BS composting drastically reduced nitrogen loss. Compared to CS composting system, the relative lower pH, the higher intensity of microbial assimilation, and the presence of water soluble Fe in BS system might jointly reduce ammonia volatilization. Consequently, BS compost product exhibited higher fertilizer values (N+P2O5+K2O=8.38%) as well as lower heavy metal levels due to the solubilization of sludge-borne heavy metals during bioleaching process. Therefore, composting of BS possesses more advantages over the CS composting process. Copyright © 2015 Elsevier Ltd. All rights reserved.

    In the area called Poligono Hidalgo, inside the Cerro Prieto IV zone in the Cerro Prieto geothermal field, BC, corrosion has occurred in the last few years on well casings and pipelines used for geothermal fluids. Corrosion test results are presented here for pipes, type API L-80 and ASTM A-53 grade B, which were subjected to condensate from wells 403 and 424. These wells have thrown corroded material from their respective casings. With these data we pinpoint corrosive conditions in this field area and determine which pipes are adequate to case wells in similar chemical, production conditions to minimize adverse effects and extend the life of the well, allowing more efficient exploitation of the deepest production zones in the reservoir. [Spanish] En el campo geotermico de Cerro Prieto, BC, dentro del area del Poligono Hidalgo en el sector conocido como Cerro Prieto IV, algunos pozos han presentado en los ultimos anos desgastes en sus tuberias de revestimiento y en las tuberias de linea para el transporte del fluido geotermico. Se presentan resultados de pruebas de corrosion con tuberias tipo API L-80 y ASTM A-53 grado B al ser sometidas al condensado de los pozos 403 y 424, los cuales han estado arrojando material de sus respectivas tuberias de revestimiento. Con estos datos se pretende conocer las condiciones corrosivas de esa zona del campo y determinar cual seria la tuberia ideal a utilizar en pozos con condiciones quimicas de produccion semejantes a fin de minimizar este efecto adverso y prolongar la vida de los pozos, a la vez que se permita la explotacion eficiente de las zonas productoras mas profundas del yacimiento.

  3. Well materials durability in case of carbon dioxide and hydrogen sulphide geological sequestration; Durabilite des materiaux de puits petroliers dans le cadre d'une sequestration geologique de dioxyde de carbone et d'hydrogene sulfure

    The geological sequestration of carbon dioxide (CO{sub 2}) and hydrogen sulphide (H{sub 2}S) is a promising solution for the long-term storage of these undesirable gases. It consists in injecting them via wells into deep geological reservoirs. The steel and cement employed in the well casing can be altered and provide pathways for leakage with subsequent human and environmental consequences. The materials ageing was investigated by laboratory experiments in geologically relevant P-T conditions. A new experimental and analysis procedure was designed for this purpose. A numerical approach was also done. The cement and steel were altered in various fluid phases at 500 bar-120 C and 500 bar-200 C: a brine, a brine saturated with H{sub 2}S-CO{sub 2}, a mixture of brine saturated with H{sub 2}S-CO{sub 2} and of supercritical H{sub 2}S-CO{sub 2} phase, a dry supercritical H{sub 2}S-CO{sub 2} phase without liquid water. In all cases, two distinct reactions are observed: the cement carbonation by the CO{sub 2} and the steel sulfidation by the H{sub 2}S. The carbonation and sulfidation are respectively maximal and minimal when they occur within the dry supercritical phase without liquid water. The textural and porosity properties of the cement are weakly affected by all the treatments at 120 C. The porosity even decreases in presence of H{sub 2}S-CO{sub 2}. But these properties are affected at 200 C when liquid water is present in the system. At this temperature, the initial properties are only preserved or improved by the treatments within the dry supercritical phase. The steel is corroded in all cases and thus is the vulnerable material of the wells. (author)

    Intelligent and statistical techniques were used to extract the hidden organic facies from well log responses in the Giant South Pars Gas Field, Persian Gulf, Iran. Kazhdomi Formation of Mid-Cretaceous and Kangan-Dalan Formations of Permo-Triassic Data were used for this purpose. Initially GR, SGR, CGR, THOR, POTA, NPHI and DT logs were applied to model the relationship between wireline logs and Total Organic Carbon (TOC) content using Artificial Neural Networks (ANN). The correlation coefficient (R2) between the measured and ANN predicted TOC equals to 89%. The performance of the model is measured by the Mean Squared Error function, which does not exceed 0.0073. Using Cluster Analysis technique and creating a binary hierarchical cluster tree the constructed TOC column of each formation was clustered into 5 organic facies according to their geochemical similarity. Later a second model with the accuracy of 84% was created by ANN to determine the specified clusters (facies) directly from well logs for quick cluster recognition in other wells of the studied field. Each created facies was correlated to its appropriate burial history curve. Hence each and every facies of a formation could be scrutinized separately and directly from its well logs, demonstrating the time and depth of oil or gas generation. Therefore potential production zone of Kazhdomi probable source rock and Kangan- Dalan reservoir formation could be identified while well logging operations (especially in LWD cases) were in progress. This could reduce uncertainty and save plenty of time and cost for oil industries and aid in the successful implementation of exploration and exploitation plans.

    Radioisotope techniques are quite useful in oil exploration and exploitation. Nuclear logging offers a way of gathering information on porosity, permeability, fluid saturations, hydrocarbon types and lithology. Some of the interesting applications in well drilling are determining depth of filtrate invasion, detection of lost circulation, drill-bit erosion control; primary cement measurements and well completions such as permanent tubular markers, perforation position marking, detection of channeling behind casing and gravel pack operations. Radioisotopes have been successfully used in optimizing production processes such as production profiling injection profiling, corrosion measurements and well to well tracer tests. (author)

    Gas hydrates, which are naturally occurring ice-like combinations of gas and water, have the potential to provide vast amounts of natural gas from the world's oceans and polar regions. However, producing gas economically from hydrates entails major technical challenges. Proposed recovery methods such as dissociating or melting gas hydrates by heating or depressurization are currently being tested. One such test was conducted in northern Canada by the partners in the Mallik 2002 Gas Hydrate Production Research Well Program. This paper describes how resistivity logs were used to determine the size of the annular region of gas hydrate dissociation that occurred around the wellbore during the thermal test in the Mallik 5L-38 well. An open-hole logging suite, run prior to the thermal test, included array induction, array laterolog, nuclear magnetic resonance and 1.1-GHz electromagnetic propagation logs. The reservoir saturation tool was run both before and after the thermal test to monitor formation changes. A cased-hole formation resistivity log was run after the test.Baseline resistivity values in each formation layer (Rt) were established from the deep laterolog data. The resistivity in the region of gas hydrate dissociation near the wellbore (Rxo) was determined from electromagnetic propagation and reservoir saturation tool measurements. The radius of hydrate dissociation as a function of depth was then determined by means of iterative forward modeling of cased-hole formation resistivity tool response. The solution was obtained by varying the modeled dissociation radius until the modeled log overlaid the field log. Pretest gas hydrate production computer simulations had predicted that dissociation would take place at a uniform radius over the 13-ft test interval. However, the post-test resistivity modeling showed that this was not the case. The resistivity-derived dissociation radius was greatest near the outlet of the pipe that circulated hot water in the wellbore

    Groundwater is a limited but important resource for fresh water supply. Differ- ent conflicting objectives are important when operating a well field. This study investigates how the management of a well field can be improved with respect to different objectives simultaneously. A framework...... for optimizing well field man- agement using multi-objective optimization is developed. The optimization uses the Strength Pareto Evolutionary Algorithm 2 (SPEA2) to find the Pareto front be- tween the conflicting objectives. The Pareto front is a set of non-inferior optimal points and provides an important tool...... for the decision-makers. The optimization framework is tested on two case studies. Both abstract around 20,000 cubic meter of water per day, but are otherwise rather different. The first case study concerns the management of Hardhof waterworks, Switzer- land, where artificial infiltration of river water...

    Considerations needed in the design and construction of model wells for nuclear log calibration are covered, with special attention to neutron porosity logging and total γ-ray logging. Pulsed neutron decay-time and spectral γ-ray logging are discussed briefly. The American Petroleum Institute calibration facility for nuclear logs is a good starting point for similar or expanded facilities. A few of its shortcomings are mentioned; they are minor. The problem of fluid saturation is emphasized. Attention is given to models made of consolidated rock and those containing unconsolidated material such as Ottawa sand. Needed precautions are listed. A similarity method is presented for estimating the porosity index of formations that are not fully saturated. (author)

    We report a case of advanced pancreatic cancer with liver and lung metastases that was well controlled over one year by combination therapy with systemic chemotherapy, radiation and hepatic arterial infusion in an outpatient setting. The patient was a 74-year-old woman. Chief complaints were back pain and anorexia. She was diagnosed with pancreas cancer with liver and lung metastases at the time of first visit. We started systemic chemotherapy with gemcitabine 1 g/body and 5-FU 1 g/body alternately every other week on an outpatient basis. At 1.5 months (M) after initiation of chemotherapy, we started radiation therapy to the main tumor at a total dose of 40 Gy. After radiation, chemotherapy was resumed. As a result, the size of the main tumor decreased but metastatic liver tumors got larger. Then we changed to combination therapy with systemic chemotherapy (gemcitabine and 5-FU) and hepatic arterial infusion (5-FU weekly). Liver metastases almost disappeared after 7.5 M. Despite all these treatments, however, the number of metastatic lung tumors increased. The patient was hospitalized for 15 M and died after 17 M. We focused on and succeeded in the prolongation of lifetime and maintenance of QOL by combination therapy with systemic chemotherapy, radiation and hepatic arterial infusion therapy.

    The ground-state energy of three-particle systems consisting of electrons and holes as found in semiconducting quantum wells is studied. The degree of confinement is determined by the quantum-well width and we can vary the dimensionality of the system from two to three dimensions. The energy levels of the system can further be altered by the application of an external magnetic field which is directed perpendicular to the well. Refs.5 (author)

    Abstract The ITS (nuclear ribosomal internal transcribed spacer) RefSeq database at the National Center for Biotechnology Information (NCBI) is dedicated to the clear association between name, specimen and sequence data. This database is focused on sequences obtained from type material stored in public collections. While the initial ITS sequence curation effort together with numerous fungal taxonomy experts attempted to cover as many orders as possible, we extended our latest focus to the family and genus ranks. We focused on Trichoderma for several reasons, mainly because the asexual and sexual synonyms were well documented, and a list of proposed names and type material were recently proposed and published. In this case study the recent taxonomic information was applied to do a complete taxonomic audit for the genus Trichoderma in the NCBI Taxonomy database. A name status report is available here: https://www.ncbi.nlm.nih.gov/Taxonomy/TaxIdentifier/tax_identifier.cgi. As a result, the ITS RefSeq Targeted Loci database at NCBI has been augmented with more sequences from type and verified material from Trichoderma species. Additionally, to aid in the cross referencing of data from single loci and genomes we have collected a list of quality records of the RPB2 gene obtained from type material in GenBank that could help validate future submissions. During the process of curation misidentified genomes were discovered, and sequence records from type material were found hidden under previous classifications. Source metadata curation, although more cumbersome, proved to be useful as confirmation of the type material designation.

There is one chapter on nuclear well-logging which is indexed separately. (UK)

  1. Dry well cooling device

    International Nuclear Information System (INIS)

    Suzuki, Hiroyuki.

    1997-01-01

    A plurality of blowing ports with introduction units are disposed to a plurality of ducts in a dry well, and a cooling unit comprising a cooler, a blower and an isolating valve is disposed outside of the dry well. Cooling air and the atmosphere in the dry well are mixed to form a cooling gas and blown into the dry well to control the temperature. Since the cooling unit is disposed outside of the dry well, the maintenance of the cooling unit can be performed even during the plant operation. In addition, since dampers opened/closed depending on the temperature of the atmosphere are disposed to the introduction units for controlling the temperature of the cooling gas, the temperature of the atmosphere in the dry well can be set to a predetermined level rapidly. Since an axial flow blower is used as the blower of the cooling unit, it can be contained in a ventilation cylinder. Then, the atmosphere in the dry well flowing in the ventilation cylinder can be prevented from leaking to the outside. (N.H.)

    This work presents a method for optimizing the itinerary of work over rigs, i.e., the search for the route of minimum total cost, and demonstrates the importance of the dynamics of reservoir behaviour. The total cost of a route includes the rig expenses (transport, assembly and operation), which are functions of time and distances, plus the losses of revenue in wells waiting for the rig, which are also dependent of time. A reservoir simulator is used to evaluate the monetary influence of the well shutdown on the present value of the production curve. Finally, search algorithms are employed to determine the route of minimal cost. The Simulated Annealing algorithm was also successful in optimizing the distribution of a list of wells among different work over rigs. The rational approach presented here is recommended for management teams as a standard procedure to define the priority of wells scheduled for work over. (author)

  5. Gratitude and Well Being

    Science.gov (United States)

    Sansone, Lori A.

    2010-01-01

    The word “gratitude” has a number of different meanings, depending on the context. However, a practical clinical definition is as follows—gratitude is the appreciation of what is valuable and meaningful to oneself; it is a general state of thankfulness and/or appreciation. The majority of empirical studies indicate that there is an association between gratitude and a sense of overall well being. However, there are several studies that indicate potential nuances in the relationship between gratitude and well being as well as studies with negative findings. In terms of assessing gratitude, numerous assessment measures are available. From a clinical perspective, there are suggested therapeutic exercises and techniques to enhance gratitude, and they appear relatively simple and easy to integrate into psychotherapy practice. However, the therapeutic efficacy of these techniques remains largely unknown. Only future research will clarify the many questions around assessment, potential benefits, and enhancement of gratitude. PMID:21191529

    1983-01-01

    The single well technique method includes measurement of parameters of groundwater flow in saturated rock. For determination of filtration velocity the dilution of radioactive tracer is measured, for direction logging the collimeter is rotated in the probe linked with the compass. The limiting factor for measurement of high filtration velocities is the occurrence of turbulent flow. The single well technique is used in civil engineering projects, water works and subsurface drainage of liquid waste from disposal sites. The radioactive tracer method for logging the vertical fluid movement in bore-holes is broadly used in groundwater survey and exploitation. (author)

  11. Fracturing formations in wells

    Energy Technology Data Exchange (ETDEWEB)

    Daroza, R A

    1964-05-15

    This well stimulation method comprises introducing through the well bore a low-penetrating, dilatant fluid, and subjecting the fluid to sufficient pressure to produce fractures in the formation. The fluid is permitted to remain in contact with the formation so as to become diluted by the formation fluids, and thereby lose its properties of dilatancy. Also, a penetrating fluid, containing a propping agent suspended therein, in introduced into contact with the fractures at a pressure substantially reduced with respect to that pressure which would have been required, prior to the fracturing operation performed using the low-penetrating dilatant fluid. The propping agent is deposited within the fractures, and thereafter, fluid production is resumed from the fractured formation. (2 claims)

  12. Sealing wells with gel

    Energy Technology Data Exchange (ETDEWEB)

    Lopez, E C

    1967-10-01

    A new system is being used in Mexico to temporarily plug producing wells. The temporary seal is a gel with a catalyst. The use of this temporary plug allows gas-lift wells to be taken off production in order to carry out emergency repairs. The gel solidifies by the action of the catalyst to a high temperature (70 - 150/sup 0/C). By locating the bottom of the tubing at the top of the production interval, the gel material will go into the permeable formation, and immediately set. When the gel has solidified, it seals off the horizon that must not be stimulated, and leaves the others exposed to the acid action. When the treatment is finished, the gel, by action of the catalyst, is liquefied and removed from the formation, being produced with the oil.

  13. Wellness interventions for anesthesiologists.

    Saadat, Haleh; Kain, Zeev N

    2018-06-01

    The review examines the different preventive measures that have been found to be useful to abolish or decrease the negative effects of burnout and increase resilience in anesthesiologists. Studies in anesthesiology cite autonomy, control of the work environment, professional relationships, leadership, and organizational justice as the most important factors in job satisfaction. Factors such as difficulty in balancing personal and professional life, poor attention to wellness, work alcoholism, and genetic factors increase an individual's susceptibility to burnout. Exposure to chronic or repeated stress instigates a spectrum of autonomic, endocrine, immunologic, and behavioral responses that activate the sympathetic-adrenal-medullary and hypothalamic-pituitary-adrenal axis. Investigating the difference in psychobiologic reactivity, as well as defining the psychological symptoms that are characteristic to individuals vulnerable to stress-induced illness, would enable scientists to better look into the modalities to eradicate the negative effects. Recent studies have shown that a combination of individual and structural changes in institutions can increase resilience in physicians. Burnout is a pathological syndrome that is triggered by constant levels of high stress. A combination of individual efforts as well as structural interventions can help to increase wellbeing in physicians.

    Over a billion dollars a year is lost by exploration and production companies drilling wells because of the lack of learn curve management (LMC) practices. This paper presents the importance of the LMC concept, what it is, why LMC has not yet been recognized as a major initiative for improving drilling cost performance. The paper discusses the different types of planning, problems with implementation of plans, the use and misuse of drilling results and data bases, and the lack of post analysis practices. The major point of the paper is to show the massive savings that can be achieved by valuing LMC, learning LMC and successfully implementing LMC. . 2 refs., 5 figs.

    Taoutaou, S.; Osman, T.M.; Mjthab, M. [Schlumberger (Syrian Arab Republic); Succar, N. [Oudeh Petroleum, Damascus (Syrian Arab Republic)

    2010-07-01

    The Oudeh Petroleum Company (OPC) has used cyclic steam (the Huff and Puff technique) since 2006 to produce heavy oil from its OPC field that has an estimated 79.49 to 95.39 million cubic meters of oil contained in the Jurassic and Triassic reservoirs of the Butmah and Kurachine formations in Syria. Accumulations of oil and gas are present in the main Oudeh structure at depths between 1300 and 2250 meters. The Huff and Puff technique involves 3 phases. In the first phase which lasts about 1 month, steam is injected at 348 degrees C and 17.MPa to melt the wax condensate in the formation in order to decrease heavy oil viscosity. Phase 2 involves 3 soaking days. In phase 3, which lasts 2 to 3 months, the production rate is doubled compared to wells without steam. The cycle is then resumed once the pressure drops. The temperature cycling can compromise the well integrity through loss of hydraulic isolation in the cement sheath and thereby reduce hydrocarbon recovery. This paper described how the OPC has managed to achieved complete well integrity using an advanced cement system in more than 200 wells exposed to steam injection temperatures up to 348 degrees C and the associated high induced thermal stresses. The methodology for risk analysis of the cement sheath failure under steam stimulation was described along with the selection criteria for the advanced cement system to withstand temperature cycling. Two case histories involving a 50 well database were presented. 5 refs., 2 tabs., 13 figs.

    2012-01-01

    Full Text Available In semiconductor laser modeling, a good mathematical model gives near-reality results. Three methods of modeling solutions from the rate equations are presented and analyzed. A method based on the rate equations modeled in Simulink to describe quantum well lasers was presented. For different signal types like step function, saw tooth and sinus used as input, a good response of the used equations is obtained. Circuit model resulting from one of the rate equations models is presented and simulated in SPICE. Results show a good modeling behavior. Numerical simulation in MathCad gives satisfactory results for the study of the transitory and dynamic operation at small level of the injection current. The obtained numerical results show the specific limits of each model, according to theoretical analysis. Based on these results, software can be built that integrates circuit simulation and other modeling methods for quantum well lasers to have a tool that model and analysis these devices from all points of view.

    In October 2007, a light crude oil spill took place in the off shore Kab121 oil well, 32 km north of the mouth of the Grijalva River, Tabasco, Mexico. In order to estimate the possible effects of oil spill on the biota in the area surrounding the spilled well, the level of different fractions of petroleum hydrocarbons were measured in fish, as well as the concentration of some chlorinated hydrocarbons and PCBs. The organisms examined were cat fish (Ariopsis felis), in addition fluorescent aromatic compounds in bile, the contaminants above mentioned and their relationship with cyotochrome P-450 and Ethoxyresorufin-O-deethylase, Glutathion-S-Transferase and catalase activities in liver were determined. The concentration of most pollutants were low, except PAHs. Spatial distribution of these compounds, as well as most biomarkers, reflected the highest exposure of fish to pollutants in the area adjacent to well, as well as in the proximity of rivers. The profile of exposure to this environment was chronic in nature and not temporary.

    The influence of well pattern involving the use of horizontal wells on the overall efficiency of the waterflooding process was analyzed. Three different scenarios were examined: (1) a pattern of using two parallel horizontal wells, one for injection, the other for production, (2) a pattern of one horizontal well for water injection and several vertical wells for production, and (3) a pattern of using vertical wells for injection and one horizontal well for production. In each case, the waterflooding process was simulated using a two phase two dimensional numerical model. Results showed that the pressure loss along the horizontal section had a large influence on the sweep efficiency whether the horizontal well was used for injection or production. Overall, the most successful combination appeared to be using vertical wells for injection and horizontal wells for production. 4 refs., 1 tab., 15 figs.

    In this paper, the feasibility of generating electricity from EGS (enhanced geothermal systems) by oilfield produced water circulating through reservoir stimulated by staged fracturing technology for horizontal wells is investigated based on the geological data of Xujiaweizi area, located in the Daqing Oilfield, northeast China. HDR (hot dry rock) resource potential assessment is carried out by using volumetric method. Reservoir stimulation is numerically simulated based on the geological data of well YS-1 and field fracturing experience in this region. Geometric dimensions and flow conductivity of the resulting fracture are imported into the hydro-thermal model to calculate the electricity generation potential of the proposed EGS power plant. An EGS design scheme is proposed based on the simulation results. The system is also evaluated from the economic and environmental aspects. The results indicate that HDR resource in Xujiaweizi area is of great potential for development. Through the staged fracturing technology for horizontal wells, electricity generation power of the proposed EGS project can roughly meet the commercial standard. For 20 years of continuous production, power generation from the proposed EGS power plant is economic feasible. Meanwhile, significant reductions in greenhouse gas emissions can be achieved. - Highlights: • Staged fracturing technology for horizontal well is used in HDR (hot dry rock) development. • Fracturing simulations and heat production simulations are combined. • A 3 MW power plant is designed in Xujiaweizi based on the simulation results

    2016-07-01

    As we embark on a journey for new homes in the new worlds to lay solid foundations, we should consider not only the survival of frontiers but also well-being of those to live in zero gravity. As a versatile science, architecture encompasses abstract human needs as well. On our new different direction in the course of the Homo sapiens evolution, we can do this with designs addressing both our needs and senses. Well-being of humans can be achieved by creating environments supporting the cognitive and social stages in the evolution process. Space stations are going through their own evolution process. Any step taken can serve as a reference for further attempts. When studying the history of architecture, window designing is discussed in a later phase, which is the case for building a spaceship as well. We lean on the places we live both physically and metaphorically. The feeling of belonging is essential here, entailing trans-humanism, which is significant since the environment therein is like a dress comfortable enough to fit in, meeting needs without any burden. Utilizing the advent of technology, we can create moods and atmospheres to regulate night and day cycles, thus we can turn claustrophobic places into cozy or dream-like places. Senses provoke a psychological sensation going beyond cultural codes as they are rooted within consciousness, which allows designers to create a mood within a space that tells a story and evokes an emotional impact. Color, amount of light, sound and odor are not superficial. As much as intangible, they are real and powerful tools with a physical presence. Tapping into induction, we can solve a whole system based on a part thereof. Therefore, fractal designs may not yield good results unless used correctly in terms of design although they are functional, which makes geometric arrangement critical.

    A project for drilling geothermal wells to produce electrical energy can be defined as a sequence of plans to get steam or geothermal fluids to satisfy a previously known demand, and, under the best possible conditions, to obtain payment. This paper presents a cost model for nine wells drilled at the Cerro Prieto geothermal field in 2005 and 2006 to supply steam to the power plants operating in the field. The cost model is based on the well cost, the initial steam production, the annual decline of steam, the drilling schedule and the break-even point for each well. The model shows the cost of steam by the ton and the sale price needed to determine the discount rate and the investment return time. [Spanish] Un proyecto de perforacion de pozos geotermicos puede definirse como una secuencia o sucesion de planes para obtener vapor o fluidos geotermicos destinados a satisfacer una demanda previamente determinada, que se emplearan principalmente para generar energia electrica, bajo las mejores condiciones para obtener un pago. Este trabajo presenta un modelo de costeo para nueve pozos en el campo geotermico de Cerro Prieto, que fueron perforados entre 2005 y 2006 como parte del suministro de vapor para las plantas generadoras que operan en este campo. El modelo de costeo se basa en el costo por pozo, la produccion inicial de vapor, la declinacion anual de vapor, los intereses de las obras de perforacion y el punto de equilibrio para cada pozo. Los resultados permiten conocer el costo de la tonelada de vapor y el precio de venta para determinar la tasa de descuento y el tiempo de retorno de la inversion.

    Motor neuron disease is a devastating neurodegenerative condition, with the majority of sporadic, non-familial cases being of unknown etiology. Several epidemiological studies have suggested that occupational exposure to chemicals may be associated with disease pathogenesis. We report the case of a patient developing progressive motor neuron disease, who was chronically exposed to pesticides and organic solvents. The patient presented with leg spasticity and developed gradually clinical signs suggestive of amyotrophic lateral sclerosis, which was supported by the neurophysiologic and radiological findings. Our report is an evidence based case of combined exposure to organochlorine (DDTs), organophosphate pesticides (OPs) and organic solvents as confirmed by laboratory analysis in samples of blood and hair confirming systematic exposure. The concentration of non-specific dialkylphosphates metabolites (DAPs) of OPs in hair (dimethyphopshate (DMP) 1289.4 pg/mg and diethylphosphate (DEP) 709.4 pg/mg) and of DDTs (opDDE 484.0 pg/mg, ppDDE 526.6 pg/mg, opDDD 448.4 pg/mg, ppDDD + opDDT 259.9 pg/mg and ppDDT 573.7 pg/mg) were considerably significant. Toluene and n-hexane were also detected in blood on admission at hospital and quantified (1.23 and 0.87 μg/l, respectively), while 3 months after hospitalization blood testing was found negative for toluene and n-hexane and hair analysis was provided decrease levels of HCHs, DDTs and DAPs. -- Highlights: ► Exposure to pesticides and organic solvents might be a risk factor for sporadic MND. ► We report a patient who developed progressive upper and lower motor neuron disease. ► The patient had a history of occupational exposure to pesticides and solvents. ► High DDTs’ levels and increased levels of DMP and DEP were measured in his hair. ► The patients’ exposure to chemicals might have played a role in MND development.

A phone call from the beneficiary to the accountant was made in an attempt to support this request. Despite being instructed not to talk to anyone, the e-mail, the phone conversation and the circumstances were all so suspicious that our colleague consulted his hierarchy, the internal audit service and us. Well done, FP Department! This is a rare case of an attempt at “social engineering”, i.e. luring someone into doing something detrimental to the Organization. The e-mail was fake.

  9. Casing study

    Roche, P.

    An unorthodox method of casing drilling used by Tesco Corporation at a gas well in Wyoming to drill deeper using casings as drillpipe is discussed. The process involves either rotating the casing as drill string or using a downhole mud motor to rotate the bit. In this instance, the surface hole and the production hole were casing-drilled to a record 8,312 feet by rotating the casing. The 8 1/2-inch surface hole was drilled with 7-inch casing to 1,200 feet using a Tesco underreamer and a polycrystalline pilot bit; drilling and cementing was completed in 12 1/2 hours. The 6 1/4-inch production hole was drilled with 4 1/2-inch casing and the bottomhole assembly was retrieved after 191 hours rotating. This case was the first in which the entire well was casing-drilled from surface to TD. Penetration rate compared favorably with conventional methods: 12 1/2 hours for casing-drilling to 18.9 hours for conventional drilling, despite the fact that the casing-drilling technology is still in its infancy. It is suggested that casing-drilling has the potential to eliminate the need for the drillpipe entirely. If these expectations were to be realised, casing-drilling could be one of the most radical drilling changes in the history of the oil and gas industry. 1 photo.

    Full Text Available Aujourd’hui, la plupart des entreprises mettent en place des projets de changements organisationnels afin de s’adapter aux modifications d’un environnement très concurrentiel. Ce faisant, elles se heurtent à des difficultés liées notamment aux situations de mal-être que ces changements peuvent induire. Notre étude vise à explorer les effets de nouvelles politiques managériales sur le bien-être émotionnel des salariés. Plus précisément, nous explorons les politiques mises en œuvre par un des sites du Groupe Essilor dans le contexte d’un changement organisationnel. Nous analysons d’un point de vue quantitatif et qualitatif les effets induits par ces politiques sur les salariés et sur la façon dont Essilor-Dijon en tient compte dans sa gestion des collaborateurs pour améliorer le bien-être au travail. À la lumière de nos résultats, il apparaît que les émotions sont au cœur de la conduite du changement, pouvant jouer le rôle de freins ou de leviers en fonction des choix managériaux.Nowadays, companies are implementing organizational change in order to be able to adapt to an increasingly competitive environment. Because of this context, firms are often confronted with problems linked to stressful situations that they themselves have brought about. We explored the policies which were applied by one of the branches of the Essilor Group in an organizational change context. First, we quantitatively and qualitatively analyzed the effects which this policy has had on stress-related issues. Second, we looked at how Essilor-Dijon took into account these effects in managing its staff so as to improve their well-being at work. Our results show that emotions appear to be at the heart of managing change and can either be obstacles or facilitators, depending on the choices made by management.Hoy en día, la mayoría de las empresas están llevando a cabo proyectos de cambio organizacional con el objetivo de adaptarse a las

    2003-09-30

    The Department of Energy (DOE) is sponsoring the Deep Trek Program targeted at improving the economics of drilling and completing deep gas wells. Under the DOE program, Pinnacle Technologies is conducting a study to evaluate the stimulation of deep wells. The objective of the project is to assess U.S. deep well drilling & stimulation activity, review rock mechanics & fracture growth in deep, high pressure/temperature wells and evaluate stimulation technology in several key deep plays. An assessment of historical deep gas well drilling activity and forecast of future trends was completed during the first six months of the project; this segment of the project was covered in Technical Project Report No. 1. The second progress report covers the next six months of the project during which efforts were primarily split between summarizing rock mechanics and fracture growth in deep reservoirs and contacting operators about case studies of deep gas well stimulation.

    1995-01-01

    The Hanford Site Groundwater Protection Management Program recognized the need to integrate monitoring well activities in a centralized manner. A key factor to Hanford Site well integration was the need to clearly identify a responsible party for each of the wells. WHC was asked to identify all wells on site, the program(s) using each well, and the program ultimately responsible for the well. This report lists the custodian and user(s) for each Hanford well and supplies a comprehensive list of all decommissioned and orphaned wells on the Hanford Site. This is the first update to the original report released in December 1993

    Losonsky, G.; Beljin, M.S.

    1992-01-01

    This paper reports on horizontal wells which offer an effective alternative to vertical wells in various environmental remediation technologies. Hydrogeological advantages of horizontal wells over vertical wells include a larger zone of influence, greater screen length, higher specific capacity and lower groundwater screen entrance velocity. Because of these advantages, horizontal wells can reduce treatment time and costs of groundwater recovery (pump-and-treat), in situ groundwater aeration (sparging) and soil gas extraction (vacuum extraction). Horizontal wells are also more effective than vertical wells in landfill leachate collection (under-drains), bioremediation, and horizontal grout injection

    A Schrödinger equation is solved numerically for a barrier in a quantum well and a quantum well in another well structure by the transfer matrix technique. Effect of structure parameters on the transmission probabilities is investigated in detail. The results suggest that symmetry plays an important role in the coupling effect between the quantum wells. The relationship between the width of the inner well and the resonant energy levels in well-in-well structures is also studied. It is found that the ground state energy and the second resonant energy decrease with increasing width of the inner well, while the first resonant energy remains constant

    Hornsby, R.G.; Miller, M.S.

    1991-01-01

    The installation method fulfilled our expectations. The entire well installation took eight writing days to complete, for an average of two wells per day. It met our Health and Safety, waste volume, environmental risk and uniform sandpack expectations. Health and Safety concerns were minimal. We found that virtually all work could be completed using Level D protection. The volume of waste produced by the well installation was extremely low. The core samples and casing scrapings were the only well installation wastes directly produced. The waste containers which required sampling prior to disposal were: Decontaminated water (330 gallons), Personnel protective equipment and water (715 gallons), Soil cores (25 gallons), Land leachate (440 gallons). Each waste type was sampled and submitted to a laboratory for analyses of full Appendix 3 plus U.S. EPA toxicity parameters. The results verified that all of the wastes could be disposed of on-site. Since the only drilling wastes were the clay core samples and the very small amount of material adhering to the casing, contamination of the new clay cap did not occur. A uniform sandpack was guaranteed through the use of a presanded well screen. The loose sand added when the casing was removed served to fill any voids. All the leachate wells have water in them, and it appears that they will function adequately. We are in the process of constructing a treatment and storage facility to manage the liquids to be extracted for off-site disposal. The long-term effectiveness of the wells will be quantified. This well installation method should be considered in situations requiring the following: expedited installation; reduced Health and Safety concerns; reduced disposal costs; reduced potential for adverse environmental impact; and comparable installation costs. The choice of this method must include considerations of the subsurface geology and the nature of any manmade materials

    Analytical solutions of the linearized governing equation are presented for periodic gas flow around a well in porous media. Two cases are considered: a fully penetrating well and a partially penetrating well. For the first case, a closed form solution is obtained, whereas for the second case the solution is in the form of eigenfunctions expansions. The results have practical application in compressed air energy storage. (authors)

    We have investigated quantum revivals of wave packets in a one-dimensional infinite square well potential containing a δ well in the middle. The time-dependent Schroedinger equation for this composite potential admits formally exact solutions. We present analytical results for revival properties in three physically motivated approximations: wave packets containing eigenstates with large numbers in the presence of an arbitrary δ well, 'shallow' and 'deep' δ wells. Analytical results in the case of a 'shallow' δ well have been tested numerically

  5. Sediment–well interaction during depressurization

    KAUST Repository

    Shin, Hosung

    2016-10-05

    Depressurization gives rise to complex sediment–well interactions that may cause the failure of wells. The situation is aggravated when high depressurization is imposed on sediments subjected to an initially low effective stress, such as in gas production from hydrate accumulations in marine sediments. Sediment–well interaction is examined using a nonlinear finite element simulator. The hydro-mechanically coupled model represents the sediment as a Cam-Clay material, uses a continuous function to capture compressibility from low to high effective stress, and recognizes the dependency of hydraulic conductivity on void ratio. Results highlight the critical effect of hydro-mechanical coupling as compared to constant permeability models: A compact sediment shell develops against the screen, the depressurization zone is significantly smaller than the volume anticipated assuming constant permeability, settlement decreases, and the axial load on the well decreases; in the case of hydrates, gas production will be a small fraction of the mass estimated using a constant permeability model. High compressive axial forces develop in the casing within the production horizon, and the peak force can exceed the yield capacity of the casing and cause its collapse. Also tensile axial forces may develop in the casing above the production horizon as the sediment compacts in the depressurized zone and pulls down from the well. Well engineering should consider: slip joints to accommodate extensional displacement above the production zone, soft telescopic/sliding screen design to minimize the buildup of compressive axial force within the production horizon, and enlarged gravel pack to extend the size of the depressurized zone.

  6. Prediction of temperature profile in oil wells

    Laderion, A.

    2000-01-01

    A mathematical model has been developed to predict the temperature distribution in well bores either offshore or inshore. It is incorporate the different activities encountered during drilling operations. Furthermore, the effect of drill collar and casings and bit rotating in a well during completion has been considered. The two dimensional approach is presented in the form of a computer program which is adopted for solution of the finite difference equations describing the heat transmission in the well bore in the form of a direct solution technique. The power law model has been selected for drilling mud and its indices have been calculated. Comparing measured data, recorded for a period of 82 hours during different activities in a drilling operation for 15/20 A-4, an exploration well in the Central North Sea with calculated results, show there is a good agreement between the prediction and measured temperatures in the well bore

    International Nuclear Information System (INIS)

    2011-03-01

    In Alberta, the presence of carbon dioxide, methane or hydrogen sulphide in water wells is common. The aim of this paper is to provide information to private owners of water wells. It is stated in this document that spurting taps or a gurgling noise indicate that there is gas in your water well; you can determine which gas it is by collecting a sample and having it analyzed. In order to address the risks associated with the presence of gas in the water well, the well pit or well pump should be properly vented to avoid any oxygen deficiency in the atmosphere. It is also possible to get rid of the gas by lowering the pump intake. It is also mentioned that the development of coalbed methane in Alberta should not contaminate private wells since regulations aimed at avoiding this have been implemented. This paper provided useful information to help private owners manage the presence of gas in their water wells.

    The quality of water in 1 421 drinking-water wells was monitored in a nationwide well water study. Samples were taken once from all wells, and during three seasons from 421 wells. The wells were selected in such a way that me sample would be as representative as possible of the quality of the drinking-water in households' own wells in rural areas. The study comprised general water quality parameters, influence of sampling season, and factors related to the type, the condition and the pollution of the wells. In part of the well waters selenium, radioactivity and pesticides were determined. The effect of plumbing materials on the quality of water was also examined. (33 refs., 148 figs., 71 tabs.)

  11. General well function for soil vapor extraction

    Science.gov (United States)

    Perina, Tomas

    2014-04-01

    This paper develops a well function applicable to extraction of groundwater or soil vapor from a well under the most common field test conditions. The general well function (Perina and Lee, 2006) [12] is adapted to soil vapor extraction and constant head boundary at the top. For groundwater flow, the general well function now applies to an extraction well of finite diameter with uniform drawdown along the screen, finite-thickness skin, and partially penetrating an unconfined, confined, and leaky aquifer, or an aquifer underneath a reservoir. With a change of arguments, the model applies to soil vapor extraction from a vadose zone with no cover or with leaky cover at the ground surface. The extraction well can operate in specified drawdown (pressure for soil vapor) or specified flowrate mode. Frictional well loss is computed as flow-only dependent component of the drawdown inside the extraction well. In general case, the calculated flow distribution is not proportional to screen length for a multiscreen well.

  12. Magnetic surveys for locating abandoned wells

    Science.gov (United States)

    ,

    1995-01-01

    Abandoned and unrecorded wells may act as conduits for the contamination of groundwater supplies by oil field brines and other pollutants. The casings of abandoned wells eventually develop leaks, which, if not properly plugged, can allow pollutants to reach freshwater aquifers that supply drinking water. Sources of pollutants include brine ponds, landfill sites, agricultural activities, industrial activities, illegal disposal sites, or accidental spills. The problem is particularly acute in regions where there are old petroleum fields or where water wells have been extensively used for agricultural irrigation. Even urban areas can contain wells that were abandoned and concealed during development. Carefully designed ground magnetic or aeromagnetic surveys can be used to locate abandoned wells by mapping the magnetic disturbances or "anomalies" produced by their steel well casings. The U.S. Geological Survey (USGS) can, at the request of other Federal, State, or local agencies, conduct, process, and interpret such surveys, or it can aid in the design and monitoring of contracts for such surveys.

    Quadricuspid pulmonic valve (QPV) is almost always a benign anomaly and is therefore usually discovered incidentally on radiographic studies or post-mortem at autopsy. Because of its rarity, the true extent of the physiology of QPV is not fully understood, and the few reported cases of it may underestimate its physiological consequences. In this case, we report on a young active-duty solider who presented for a well check-up and was discovered on imaging to have a QPV. We also review the most recent literature and provide recommendations regarding the most effective diagnostic modalities.

    2017-12-01

    The U.S. Strategic Petroleum Reserve (SPR) holds a reserve of crude oil ( 700 million barrels) to help ease any interruptions in oil import to the United States. The oil is stored in a set of 63 underground caverns distributed across four sites along the U.S. Gulf Coast. The caverns were solution mined into salt domes at each of the four sites. The plastic nature of the salt is beneficial for the storage of crude oil as it heals any fractures that may occur in the salt. The SPR is responsible for operating and maintaining the nearly 120 wells used to access the storage caverns over operational lifetimes spanning decades. Salt creep can induce deformation of the well casing which must be remediated to insure cavern and well integrity. This is particularly true at the interface between the plastic salt and the rigid caprock. The Department of Energy, the SPR Management and Operations contractor, and Sandia National Laboratories has developed a multidimensional well-grading system for the salt cavern access wells. This system is designed to assign numeric grades to each well indicating its risk of losing integrity and remediation priority. The system consists of several main components which themselves may consist of sub-components. The main components consider such things as salt cavern pressure history, results from geomechanical simulations modeling salt deformation, and measurements of well casing deformation due to salt creep. In addition, the geology of the salt domes and their overlying caprock is also included in the grading. These multiple factors are combined into summary values giving the monitoring and remediation priority for each well. Sandia National Laboratories is a multimission laboratory managed and operated by National Technology and Engineering Solutions of Sandia LLC, a wholly owned subsidiary of Honeywell International Inc. for the U.S. Department of Energy's National Nuclear Security Administration under contract DE-NA0003525.

    One aspect in our troubling economy that seems to be flourishing is the growing number of employers implementing consumer-driven health (CDH) plans and wellness programs. This article describes the primary areas of participant behavior that consumerism seeks to change and the fundamental factors a "consumer-focused" health care strategy must include. The authors outline issues employers must address when designing a successful incentive program and its accompanying communications strategy. A case study of a company that has a 70% enrollment rate in its CDH plans shows how an integrated consumerism and wellness strategy can slow the rate of health care cost increases for both the employee and employer.

  2. Neutron die-away well logging

    Jacobson, L.A.

    1976-01-01

    Neutron die-away well logging is extensively used for the location and monitoring of hydrocarbon zones in cased wells. Casing prohibits the use of conventional open-hole electrical resistivity methods. Through an appropriate interpretation of the measured capture cross-section, it is possible to determine the fractional hydrocarbon content of the rock pore volume, provided that the interstitial water is moderately saline (Σ/sub w/ greater than or equal to .035 cm -1 ). Special sealed D-T accelerator tubes and high voltage supplies have been developed for this purpose. They must fit into a 25 mm design circle and operate at 175 0 C, producing approximately 10 8 neutron/sec average in repetitive bursts. In the Schlumberger method an electronic servo-system adjusts burst and measure-gate timing to minimize statistical uncertainty regardless of die-away time

  3. Preserving Employee Privacy in Wellness.

    Science.gov (United States)

    Terry, Paul E

    2017-07-01

    The proposed "Preserving Employee Wellness Programs Act" states that the collection of information about the manifested disease or disorder of a family member shall not be considered an unlawful acquisition of genetic information. The bill recognizes employee privacy protections that are already in place and includes specific language relating to nondiscrimination based on illness. Why did legislation expressly intending to "preserve wellness programs" generate such antipathy about wellness among journalists? This article argues that those who are committed to preserving employee wellness must be equally committed to preserving employee privacy. Related to this, we should better parse between discussions and rules about commonplace health screenings versus much less common genetic testing.

  4. CEMENT SLURRIES FOR GEOTHERMAL WELLS CEMENTING

    Directory of Open Access Journals (Sweden)

    Nediljka Gaurina-Međimurec

    1994-12-01

    Full Text Available During a well cementing special place belongs to the cement slurry design. To ensure the best quality of cementing, a thorough understanding of well parameters is essential, as well as behaviour of cement slurry (especially at high temperatures and application of proven cementing techniques. Many cement jobs fail because of bad job planning. Well cementing without regarding what should be accomplished, can lead to well problems (channels in the cement, unwanted water, gas or fluid production, pipe corrosion and expensive well repairs. Cementing temperature conditions are important because bot-tomhole circulating temperatures affect slurry thickening time, arheology, set time and compressive strength development. Knowing the actual temperature which cement encounters during placement allows the selection of proper cementing materials for a specific application. Slurry design is affected by well depth, bottom hole circulating temperature and static temperature, type or drilling fluid, slurry density, pumping time, quality of mix water, fluid loss control, flow regime, settling and free water, quality of cement, dry or liquid additives, strength development, and quality of the lab cement testing and equipment. Most Portland cements and Class J cement have shown suitable performances in geot-hermal wells. Cement system designs for geothermal wells differ from those for conventional high temperature oil and gas wells in the exclusive use of silica flour instead of silica sand, and the avoidance of fly ash as an extender. In this paper, Portland cement behaviour at high temperatures is described. Cement slurry and set cement properties are also described. Published in literature, the composition of cement slurries which were tested in geothermal conditions and which obtained required compressive strength and water permeability are listed. As a case of our practice geothermal wells Velika Ciglena-1 and Velika Ciglena-la are described.

    The particle losses from a magnetic well having an octahedral symmetry are considered. The cusp, classical diffusion, and Bohm diffusion losses are computed. Results show that: Cusp losses can be compensated for by ion beam in the Hershkowitz equation prevails. Otherwise, the losses will have to be diminished by some other means; Classical diffusion losses are relatively small; and Bohm diffusion losses are very large, should it prevail, but that is unlikely to be the case in the configuration under consideration

    WellCAP is a well control accreditation program devised and implemented by the International Association of Drilling Contractors (IADC). It is a worldwide comprehensive system that defines a well control training curriculum, establishes minimum standards and recommends guidelines for course structure. The program began in mid-1993 and is viewed as a means for training institutions to demonstrate industry recognition to customers, contractors and local governments. Schools can apply to have their courses accredited. The accreditation system is administered by a review panel. The application process requires that the school perform a detailed review of its curriculum and operations and bring them in line with the WellCAP curriculum and accreditation criteria. Currently, more than 75 schools around the world have requested application materials for WellCAP. To date fifteen schools have been fully accredited

    Ledgerwood, R.K.

    1993-01-01

    Protection of Hanford Site groundwater resources and assessment of the effects of their use or contamination upon public safety are required by federal and state regulations and U.S. Department of Energy (DOE) policy, (DOE, 1989). Compliance with constraints applicable to the use of existing wells requires assessment as to the suitability for use and needs for rehabilitation, remediation or decommissioning of existing groundwater wells and other boreholes potentially affecting aquifers beneath the Hanford Site. Approximately 3,500 groundwater wells and vadose zone boreholes had been drilled on the Hanford Site prior to 1989, over 2,900 still exist. Most of these boreholes were drilled prior to 1987 and do not conform to presently accepted construction standards intended to protect groundwater resources. Approximately 260 wells have been installed since 1987. These wells were constructed to current standards for well construction which mandate seals between the permanent casing and the formation to prevent potential migration of contaminated liquid. Several programs presently construct and/or utilize existing and newly drilled wells to provide characterization and groundwater monitoring data. The programs are summarized

  11. Groundwater monitoring for deep-well injection

    International Nuclear Information System (INIS)

    Chia, Y.; Chiu, J.

    1994-01-01

    A groundwater monitoring system for detecting waste migration would not only enhance confidence in the long-term containment of injected waste, but would also provide early warnings of contamination for prompt responses to protect underground sources of drinking water (USDWs). Field experiences in Florida have demonstrated monitoring water quality and fluid pressure changes in overlying formations is useful in detecting the upward migration of injected waste. Analytical and numerical solutions indicate changes in these two monitoring parameters can vary on the basis of hydrogeologic characteristics, operation conditions, and the distances from the injection well to the monitoring wells and to the preferential hydrologic conduits. To detect waste migration through defects around the wellbore or the leaky containment interval, groundwater monitoring wells should be placed as close as possible to an injection well. In the vertical direction, a monitoring well completed in a permeable interbed within the containment interval is expected to have the highest potential for detecting upward migration. Another acceptable horizon for groundwater monitoring is the lower portion of the buffer brine aquifer immediately above the containment interval. Monitoring wells in USDWs may be needed when waste has been detected in deeper formations or when leakage out of well casings poses a concern. A monitoring well open to the injection interval is of little value in alleviating the concerns of long-term upward migration. Moreover, the installation of the well could create additional preferential pathways. Complications in groundwater monitoring may arise at existing injection sites, especially with prior releases. It is also important to recognize that monitoring in the vicinity of the wellbore may not be effective for detecting waste migration through unidentified unplugged wells or undetected transmissive fractures

    1994-08-01

    A report is presented on the final phase of an energy research program conducted by the U.S. Department of Energy (DOE) involving two geothermal well sites in the State of Louisiana-the Gladys McCall site and the Willis Hulin site. The research program was intended to improve geothermal technology and to determine the efficacy of producing electricity commercially from geopressured resource sites. The final phase of the program consisted of plug and abandonment (P&A) of the wells and restoration of the well sites. Restoration involved (a) initial soil and water sampling and analysis; (b) removal and disposal of well pads, concrete, utility poles, and trash; (c) plugging of monitor and freshwater wells; and (d) site leveling and general cleanup. Restoration of the McCall site required removal of naturally occurring radioactive material (NORM), which was costly and time-consuming. Exhibits are included that provide copies of work permits and authorizations, P&A reports and procedures, daily workover and current conditions report, and cost and salvage reports. Site locations, grid maps, and photographs are provided.

  15. On the Importance of Well-Being

    DEFF Research Database (Denmark)

    Rodogno, Raffaele

    2008-01-01

    Many among philosophers and non-philosophers would claim that well-being is important in moral theory because it is important to the individual whose well-being it is. The exact meaning of this claim, however, is in need of clarification. Having provided that, I will present a charge against it...... central theories in normative ethics. I will focus on Scanlon’s discussion in particular because it affords us with two criteria for the assessment of the importance for a person of a value-concept such as well-being. I will claim that much of Scanlon’s case rests on the idea that well......-being is an inclusive good, a good constituted by other things that are good in and for themselves. Then, I will put forward a case against Scanlon’s challenge by (1) showing that inclusiveness, when properly understood, does not lead to the conclusion Scanlon is led to and (2) showing that on at least the reading...

  16. Horizontal well impact on heavy oil supply

    International Nuclear Information System (INIS)

    Bowers, B.; Bielecki, J.; Hu, J.; Wall, B.; Drummond, K.

    1993-01-01

    Horizontal wells can take advantage of gravity drainage mechanisms, which can be important in conventional heavy oil and bitumen recovery. Horizontal drilling will impact on the development of established conventional heavy oil pools by infill drilling and application of enhanced recovery techniques. There will also be an impact on the development of extensions to established and newly discovered heavy oil pools, as well as a major impact on development of bitumen resources. To assess the impact of horizontal drilling on heavy oil supply, high-impact and low-impact scenarios were evaluated under specified oil-price assumptions for four heavy oil areas in Saskatchewan and Alberta. Horizontal well potential for infill drilling, waterflood projects, and thermal projects was assessed and estimates were made of such developments as reserves additions and heavy oil development wells under the two scenarios. In the low case, projected supply of conventional heavy oil and bitumen stabilizes at a level in the 90,000-94,000 m 3 /d after 1994. In the high case, overall supply continuously grows from 80,000 m 3 /d in 1992 to 140,000 m 3 /d in 2002. Through application of horizontal drilling, reserves additions in western Canada could be improved by ca 100 million m 3 by 2002. 14 figs., 6 tabs

    Crowe, B.; Morley, R.

    1992-01-01

    The Lathrop Wells volcanic center is located 20 km south of the potential Yucca Mountain site, at the south end of the Yucca Mountain range. This paper discusses a detailed Study Plan which was prepared describing planned geochronology and field studies to assess the chronology of the Lathrop Wells volcanic center and other Quaternary volcanic centers in the region. A paper was published discussing the geomorphic and soil evidence for a late Pleistocene or Holoceno age for the main cone of the center. The purpose of this paper was to expose the ideas concerning the age of the Lathrop Wells center to scientific scrutiny. Additionally, field evidence was described suggesting the Lathrop Wells center may have formed from multiple eruptive events with significant intervals of no activity between events. This interpretation breaks with established convention in the volcanological literature that small volume basalt centers are monogenetic

    A multipole magnetic well for plasma confinement includes a plurality of current-carrying coils placed on planes corresponding to the facets of a regular polyhedron that can be symmetrically circumscribed about a sphere. The direction of current in the coils is such as to minimize the flux density at the center of the polyhedron, thereby providing a confinement well with three-dimensional symmetry having an increasing flux density in all directions from the center. 16 claims, 18 figures

  6. Λ and Σ well depth

    International Nuclear Information System (INIS)

    Satoh, Eiji

    1982-01-01

    The Λ well depth was calculated by taking into account the effect of the ΛΣ conversion. Takahashi et al. obtained the separate type of potentials which described the hyperon-nucleon interaction up to p waves. Two types of the potentials among several types they obtained were used to calculate the Λ well depth. The G matrix was easily calculated, and the Λ well depth was obtained by integrating the G matrix in momentum space up to the Fermi surface. The effect of the ΛΣ conversion was given by an equation. The total Λ well depth was estimated to be 9.13 MeV and 49.36 MeV for each type of potential, respectively. It was concluded that the argument by Bodmer et al. was not correct. The Σ well depth was also calculated using the potential obtained by Takahashi et al. for I = 1/2 and the one obtained by Σ + p → Σ + p scattering data for I = 3/2. The obtained value 35.30 MeV may be overestimated, and the experimental value is expected to be in the range from 20 MeV to 30 MeV. (Ito, K.)

  7. Modeling multi-lateral wells

    1998-12-31

    A method for modeling multi-lateral wells by using a computational scheme embedded in a general-purpose, finite difference simulator was described. The calculation of wellbore pressure profile for each lateral included the frictional pressure drop along the wellbore and proper fluid mixing at lateral connection points. To obtain a good production profile the Beggs and Brill correlation, a homogenous flow model, and the model proposed by Ouyang et al, which includes an acceleration term and accounts for the lubrication effect due to radial influx, were implemented. Well performance prediction results were compared using the three models. The impact of different tubing sizes on the well performance and the prediction contribution from each lateral were also studied. Results of the study in the hypothetical example and under normal field operating conditions were reviewed. 7 refs., 10 tabs., 3 figs.

    Freudlich, Alex; Ignatiev, Alex

    2009-01-01

    Thermophotovoltaic cells containing multiple quantum wells have been invented as improved means of conversion of thermal to electrical energy. The semiconductor bandgaps of the quantum wells can be tailored to be narrower than those of prior thermophotovoltaic cells, thereby enabling the cells to convert energy from longer-wavelength photons that dominate the infrared-rich spectra of typical thermal sources with which these cells would be used. Moreover, in comparison with a conventional single-junction thermophotovoltaic cell, a cell containing multiple narrow-bandgap quantum wells according to the invention can convert energy from a wider range of wavelengths. Hence, the invention increases the achievable thermal-to-electrical energy-conversion efficiency. These thermophotovoltaic cells are expected to be especially useful for extracting electrical energy from combustion, waste-heat, and nuclear sources having temperatures in the approximate range from 1,000 to 1,500 C.

    Past liquid waste disposal practices within the 100-N Area have resulted in the contamination of the underlying sediments and groundwater. The release of large volumes of liquid effluent to the 1301-N and 1325-N Liquid Waste Disposal Facilities caused the transport of 90 Sr and other contaminants to the groundwater. Further discussion of 100-N Area hydrogeology is provided in Hartman and Lindsey (1993). A pump-and-treat system combined with a vertical barrier is the preferred alternative for the N Springs Expedited Response Action.

  13. Recommended well drilling and testing program

    Long, J.; Wilson, C.

    1978-07-01

    A well drilling and testing program is recommended by Lawrence Berkeley Laboratory to identify the hydrology of deep basalts in the Pasco Basin. The ultimate objective of this program is to assist in determining the feasibility of locating a nuclear waste repository on the Hanford Reservation. The recommended program has been staged for maximum effectiveness. In the first stage, six wells have been identified for drilling and testing which, when coupled with existing wells, will provide sufficient data for a preliminary overview of basin hydrology and a preliminary determination of the hydrologic suitability of the deep basalt for a repository site. The rate at which the first stage wells are drilled and tested will depend upon the date at which a preliminary determination of site suitability is required. It was assumed that a preliminary determination of suitability would be required in 1980, in which case all six first stage wells would be drilled in FY 1979. If the results of the first stage analysis are favorable for repository siting, tentative repository sites can be identified and a second stage hydrology program can be implemented to provide the necessary details of the flow system. To accomplish this stage, a number of deep wells would be required at locations both inside and outside the basin, with specific sites to be identified as the work progresses to obtain maximum utility of existing data. A program is recommended for testing in each new well and for completion of testing in each existing well. Recommended tests include borehole geophysics, pressure and permeability testing, geochemical sampling, tracer testing, hydrofracturing and borehole fracture logging. The entire data collection program is oriented toward providing the information required to establish and verify an accurate numerical model of the Pasco Basin

    2008-10-15

    This paper discussed a steam assisted gravity drainage (SAGD) pilot project currently being conducted in Venezuela's Orinoco Belt. A risk assessment was conducted as part of the pilot program in order to evaluate the use of single barrier completions in conjunction with a blowout response plan. The study considered 3 options: (1) an isolated double barrier completion with a downhole safety valve (DHSV) in the production tubing string and a packer in the production casing annulus; (2) a partially isolated completion with no DHSV and a packer in the production casing annulus; and (3) an open single barrier completion with no additional downhole barriers. A reservoir model was used to assess the blowout flowing potential of SAGD well pairs. The probability of a blowout was estimated using fault tree analysis techniques. Risk was determined for various blowout scenarios, including blowouts during normal and workover operations, as well as blowouts through various flow paths. Total risk for each completion scenario was also determined at 3 different time periods within the production life of the well pair. The possible consequences of a blowout were assessed using quantitative consequence models. Results of the study showed that environmental and economic risks were much higher for the open completion technique. Higher risks were also associated with the earlier life of the completion strings. 20 refs., 3 tabs., 19 figs.

    1986-04-01

    In this study the behavior of fracture systems under well test conditions and methods for analyzing well test data from fractured media are investigated. Several analytical models are developed to be used for analyzing well test data from fractured media. Numerical tools that may be used to simulate fluid flow in fractured media are also presented. Three types of composite models for constant flux tests are investigated. Several slug test models with different geometric conditions that may be present in fractured media are also investigated. A finite element model that can simulate transient fluid flow in fracture networks is used to study the behavior of various two-dimensional fracture systems under well test conditions. A mesh generator that can be used to model mass and heat flow in a fractured-porous media is presented. This model develops an explicit solution in the porous matrix as well as in the discrete fractures. Because the model does not require the assumptions of the conventional double porosity approach, it may be used to simulate cases where double porosity models fail.

  1. Evaluating an employee wellness program.

    Science.gov (United States)

    Mukhopadhyay, Sankar; Wendel, Jeanne

    2013-12-01

    What criteria should be used to evaluate the impact of a new employee wellness program when the initial vendor contract expires? Published academic literature focuses on return-on-investment as the gold standard for wellness program evaluation, and a recent meta-analysis concludes that wellness programs can generate net savings after one or two years. In contrast, surveys indicate that fewer than half of these programs report net savings, and actuarial analysts argue that return-on-investment is an unrealistic metric for evaluating new programs. These analysts argue that evaluation of new programs should focus on contract management issues, such as the vendor's ability to: (i) recruit employees to participate and (ii) induce behavior change. We compute difference-in-difference propensity score matching estimates of the impact of a wellness program implemented by a mid-sized employer. The analysis includes one year of pre-implementation data and three years of post-implementation data. We find that the program successfully recruited a broad spectrum of employees to participate, and it successfully induced short-term behavior change, as manifested by increased preventive screening. However, the effects on health care expenditures are positive (but insignificant). If it is unrealistic to expect new programs to significantly reduce healthcare costs in a few years, then focusing on return-on-investment as the gold standard metric may lead to early termination of potentially useful wellness programs. Focusing short-term analysis of new programs on short-term measures may provide a more realistic evaluation strategy.

    Full Text Available In an ageing world, the potential for ageing well in older people is still relatively unexplored.Literature has suggested that a sense of coherence (SOC is an important factor with regard to retaining a good quality of life in old age. To explore whether satisfaction with life (SWL, as well as sociodemographic, health- and lifestyle-related variables, are predictors of SOC in a community-dwelling sample of older adults and to assess significant differences in SOC amongst the four nationalities studied. Cross-national research encompassing a community-dwelling sample of 454 older adults aged 75 years and above was undertaken. Sense of coherence was assessed using the Orientation to Life Questionnaire and Satisfaction with Life (SWL was measured using the Satisfaction with Life Scale. Structural equation modelling was used to investigate a structural model of the self-reported SOC, comprising sociodemographic variables (age, gender, marital status, professional status, educational level, family’s annual income and standard of living arrangements, as well as SWL, lifestyle and health-related (physical activity and recent disease characteristics. Significant predictors were physical activity (β = 0.804; p < 0.001, recent disease (β = 0.501; p < 0.001 and SWL (β = 0.07; p = 0.004.These variables accounted for approximately 57.5%of the variability of SOC. Moreover, differences with regard to SOC were also found amongst the four nationality groups (F(3= 5.204; p = 0.002. Physical activity is the strongest predictor of self-reported SOC. Other predictors are the absence of a recent disease and SWL. The four nationalities presented significant differences with regard to SOC. This study highlighted the need for understanding the potential factors (in particular physical activity and further health-related characteristicsthat impact on older adults’ SOC.

    A well device is proposed for removing small objects. It contains a hollow housing with worm and crown installed with the possibility of rotation in relation to the housing. It is distinguished by the fact that in order to increase reliability of holding the trapped objects, on the lower end of the housing there is a disc which forms with the housing a chamber for the trapped objects. In this case the disc is made with sector slit, one of whose sidewalls is superposed with the worm blade rigidly connected to the disc, while along the other side wall a plate is vertically attached.

    Shell U.K. Exploration and Production, Operator in the U.K. sector of the North Sea for Shell and Esso, has adopted a corporate strategy in line with the 'Drilling in the Nineties' concept proposed by Shell International Petroleum Maatschappij B.V. (SIPM) for all Shell Operating Companies. Within Shell Expro the 'Drilling in the Nineties' concept has been broadened to incorporate the drilling, well services and equipment supply areas with the resultant name change to iWell Engineering in the Nineties'. (WIN 90's). This strategy has now been implemented and has substantially changed the modus operandi between operator and contractor with a strong emphasis on long term partnership relations with lead contractors. This paper summarises the strategy that has been developed, the implications of implementing this strategy; the implications to both a major operator and numerous contractor suppliers; the results to date; and the course of future partnership relations.

    One rather fundamental question concerning supergravity remains unresolved: Is supergravity a well-posed field theory? That is, does a set of certain (Cauchy) data specified on some initial spacelike surface determine a unique, causally propagating spacetime solution of the supergravity field equations (at least in some finite neighborhood of the initial surface)? In this paper, the authors give a very brief report on work directed towards answering this question. (Auth.)

    Giles, J.R.; Dooley, K.J.

    1997-01-01

    A Gamma Spectroscopy Logging System (GSLS) has been developed to study sub-surface radionuclide contamination. The absolute counting efficiencies of the GSLS detectors were determined using cylindrical reference sources. More complex borehole geometries were modeled using commercially available shielding software and correction factors were developed based on relative gamma-ray fluence rates. Examination of varying porosity and moisture content showed that as porosity increases, and as the formation saturation ratio decreases, relative gamma-ray fluence rates increase linearly for all energies. Correction factors for iron and water cylindrical shields were found to agree well with correction factors determined during previous studies allowing for the development of correction factors for type-304 stainless steel and low-carbon steel casings. Regression analyses of correction factor data produced equations for determining correction factors applicable to spectral gamma-ray well logs acquired under non-standard borehole conditions

  10. Radon in private drinking water wells

    At least 10 % of inhabitants in the Czech Republic are supplied with water from private sources (private wells, boreholes). With the increasing cost of water, the number of people using their own sources of drinking water will be likely to increase. According to the Decree of the State Office for Nuclear Safety about the Radiation Protection 307/2002 as amended by Decree 499/2005, the guideline limit for the supplied drinking water ('drinking water for public supply') for radon concentration is 50 Bq.l -1 . This guideline does not apply to private sources of drinking water. Radon in water influences human health by ingestion and also by inhalation when radon is released from water during showering and cooking. This paper presents results of measurements of radon concentrations in water from private wells in more than 300 cases. The gross concentration of alpha-emitting radionuclides and the concentrations of radium and uranium were also determined. (authors)

    2003-07-01

    This paper reviewed the experience that Tesco has gained by drilling several wells using only casings as the drill stem. Tesco has manufactured a mobile and compact hydraulic drilling rig called the Casing Drilling {sup TM} system. The system could be very effective and efficient for exploration and development of coalbed methane (CBM) reserves which typically require extensive coring. Continuous coring while drilling ahead, along wire line retrieval, can offer time savings and quick core recovery of large diameter core which is typically required for exploration core desorption tests. The proposed system may also have the potential to core or drill typically tight gas sands or underbalanced wells with air or foam. This would reduce drilling fluid damage while simultaneously finding gas. Compared to conventional drill pipes, Casing Drilling {sup TM} could also be effective with water production from shallow sands because of the smaller annual clearance which requires less air volumes to lift any produced water. 9 figs.

    Morse oilfield, in eastern Gray County of the Texas Panhandle, was originally developed between 1928 and 1937. It is but a very small part of the huge Texas Pandhandle field, which covers over 200,000 productive acres, containing 12,500 active wells with a cumulative production of one billion barrels of oil. The field produces from Permian age dolomites and the Pennsylvanian Granite Wash. This paper reports on multiple production techniques that have been used over the years with varying levels of success. Acidizing techniques in the late 1930s increased development, but the advent of hydraulic fracturing resulted in extensive development. The primary drive mechanism was solution-gas drive. Approximately one-fourth of Panhandle field has been subjected to gas injection, resulting in an estimated 50 million barrels of additional oil production. In 1955, waterflooding appeared to offer the most economical possibility of increasing ultimate recovery from the Brown Dolomite reservoir. The Morse Brown Dolomite pilot flood in Gray County and another Brown Dolomite pilot flood in Hutchinson County were the first two successful pilot floods in Panhandle field. The Morse flood has a total of 40 oil and 27 water injection wells on 500 flood acres. Morse field has a cumulative production of 15.7 million barrels of oil. The operating company, Future Petroleum Corp., a Dallas-based independent, believes that a third alternative using horizontal drilling has the potential to increase production. And it appears that the Brown Dolomite formation of Morse field offers the right combination of factors to attempt this type of venture

    Matrix acidizing is a stimulation technique only applicable to wells with surrounding damage. It is therefore very important to differentiate the real formation damage from the damage caused by flow Ni dynamic effects. The mechanical damage corresponds to flow restrictions caused by partial penetration, poor perforation as well as to reduce diameters of the production tubing. The dynamic effects are generated by inertia caused by high flow rates and high-pressure differentials. A common practice in our oil fields is to use a general formulation as acid treatment, most of the times without previous lab studies that guarantee the applicability of the treatment in the formation. Additionally, stimulation is randomly applied even treating undamaged wells with negative results and in the best of the cases, loss of the treatment. The selection of the well for matrix stimulation is an essential factor for the success of the treatment. Selection is done through the evaluation of the skin factor (S) and of the economic benefits of reducing the skin in comparison to the cost of the work. The most appropriate tool for skin evaluation is a good pressure test where the radial flow period can be identified. Nevertheless, we normally find-outdated tests most of the times taken with inaccurate tools. The interpretation problem is worsened by completions in which there is simultaneous production from several sand packages and it is difficult to individually differentiate damage factors. This works states a procedure for the selection of wells appropriate for stimulation; it also proposes a method to evaluate the skin factor when there are no accurate interpretations of the pressure tests. A new and increasingly applied methodology to treat wells with high water cuts, which are usually discarded due to the risk of stimulating water zones, is also mentioned

    Ever rising daily operating cost for offshore operations make the risk of running into drilling problems due to torque and drag developments in extended reach applications a growing concern. One option to reduce cost related to torque and drag problems can be to monitor torque and drag trends in real time without additional workload on the platform drilling team. To evaluate observed torque or drag trends it is necessary to automatically recognize operations and to have a 'standard value' to compare the measurements to. The presented systematic approach features both options - fully automated operations recognition and real time analysis. Trends can be discussed between rig- and shore-based teams, and decisions can be based on up to date information. Since the system is focused on visualization of real-time torque and drag trends, instead of highly complex and repeated simulations, calculation time is reduced by comparing the real-time rig data against predictions imported from a commercial drilling engineering application. The system allows reacting to emerging stuck pipe situations or developing cuttings beds long before the situations become severe enough to result in substantial lost time. The ability to compare real-time data with historical data from the same or other wells makes the system a valuable tool in supporting a learning organization. The system has been developed in a joint research initiative for field application on the development of an offshore heavy oil field in New Zealand. (orig.)

    Kramers turnover theory is solved for a particle in a symmetric triple well potential for temperatures above the crossover temperature between tunneling and activated barrier crossing. Comparison with the turnover theory for a double well potential shows that the presence of the intermediate well always leads to a decrease of the reaction rate. At most though, the rate is a factor of two smaller than in the case of a double well potential. (author)

  20. Nuclear well logging in hydrology

    International Nuclear Information System (INIS)

    1971-01-01

    The optimum development of regional and local groundwater resources requires a quantitative evaluation of its aquifers and aquicludes, and of the physical and chemical properties relevant to the recharge to and withdrawal of water from them. If an understanding of the groundwater regime is to be obtained, geological observations at outcrop must be augmented by subsurface measurements of the strata and the waters they contain. Measurements of many hydrological and geological parameters can be made in situ by nuclear geophysical well-logging methods. Very simply, well logging consists of lowering a measuring probe into a well and making a continuous record of the variations of a particular parameter with depth. In most circumstances, repetition of the measurements under differing hydrodynamic conditions results in a better definition of the flow regime in the aquifer. Nuclear well-logging techniques have for some years been capable of solving a number of the sub-surface measurement problems faced by hydrogeologists. However, the present usage of these methods varies from country to country and the literature concerning applications is scattered in the professional journals of several disciplines. The objective of this report is to include in a single reference volume descriptions of the physical principles of nuclear logging methods, their applications to hydrogeological problems and their limitations on a level suitable for the practising hydrologists with a limited knowledge of nuclear physics. The Working Group responsible for compiling the report recommended that it should cover a broad spectrum of hydrogeological investigations and problems. For example, it saw no valid reason to distinguish for the purposes of the report between well-logging applications for water-supply purposes and for water-flooding studies in the petroleum industry. Neutron measurements made for soil-moisture determinations in the unsaturated zone have been specifically omitted, however, as

    Davidson, Anthony Lee, III

    Today's growing energy demands require new technologies to provide high efficiency clean energy. Thermoelectrics that convert heat to electrical energy directly can provide a method for the automobile industry to recover waste heat to power vehicle electronics, hence improving fuel economy. If large enough efficiencies can be obtained then the internal combustion engine could even be replaced. Exhaust temperature for automotive application range from 400 to 800 K. In this temperature range the current state of the art materials are bulk Si1-xGex alloys. By alternating layers of Si and Si1-xGex alloy device performance may be enhanced through quantum well effects and variations in material thermal properties. In this study, superlattices designed for in-plane operation with varying period and crystallinity are examined to determine the effect on electrical and thermal properties. In-plane electrical resistivity of these materials was found to be below the bulk material at a similar doping at room temperature, confirming the role of quantum wells in electron transport. As period is reduced in the structures boundary scattering limits electron propagation leading to increased resistivity. The Seebeck coefficient measured at room temperature is higher than the bulk material, additionally lending proof to the effects of quantum wells. When examining cross-plane operation the low doping in the Si layers of the device produce high resistivity resulting from boundary scattering. Thermal conductivity was measured from 77 K up to 674 K and shows little variation due to periodicity and temperature, however an order of magnitude reduction over bulk Si1-xGex is shown in all samples. A model is developed that suggests a combination of phonon dispersion effects and strong boundary scattering. Further study of the phonon dispersion effects was achieved through the examination of the heat capacity by combining thermal diffusivity with thermal conductivity. All superlattices show a

    A substantial improvement in the useful life and efficiency of a deep-well scintillation detector is achieved by a unique construction wherein the steel cylinder enclosing the sodium iodide scintillation crystal is provided with a tapered recess to receive a glass window which has a high transmittance at the critical wavelength and, for glass, a high coefficient of thermal expansion. A special high-temperature epoxy adhesive composition is employed to form a relatively thick sealing annulus which keeps the glass window in the tapered recess and compensates for the differences in coefficients of expansion between the container and glass so as to maintain a hermetic seal as the unit is subjected to a wide range of temperature

    HIV exceptionalism (and disease-specific programs generally) garner both unbalanced funding and the most talented personnel, distorting local health priorities. In support of HIV exceptionalism, the successful mobilization of significant global health sector resources was not possible prior to HIV. Both sides of the debate have merits; rather than perpetuating polarization, we suggest that sustained improvements in global health require creating a prevention infrastructure to meet multiple health challenges experienced by local communities. We propose four fundamental shifts in HIV and disease prevention: (1) horizontally integrating prevention at one site locally, with priorities tailored to local health challenges and managed by local community leaders; (2) using a family wellness metaphor for services, not disease prevention; (3) implementing evidence-based prevention programs (EBPP) based on common principles, factors, and processes, rather than replication of specific programs; and (4) utilizing the expertise of private enterprise to re-design EBPP into highly attractive, engaging, and accessible experiences.

    Well logging techniques exploit interactions of gamma photons and neutrons with atoms. Interactions of neutrons of different energies with atoms allow the detection and evaluation of the weight percentage of several elements composing the rocks (C, O, Si, Ca, Fe, S); spectrometry of gamma rays produced by thermal neutron absorption allows for the weight percentage determination of Si, Ca, Fe, S, Cl, H, Ti and Gd, etc. High resolution detectors (germanium doped by Li, at liquid nitrogen temperature) allow the recognition of more elements. Other techniques involving neutrons consist in determining the population in epithermal neutrons at a certain distance of the neutron source (measurement of the hydrogen index). By analyzing the intensity of the gamma flux produced by Compton scattering, the electronic and bulk densities of the rocks are measured. All these data lead to the detection and evaluation of ore deposits (uranium and potassium) and coal, and determination of the lithology, the main minerals composing the rocks, petrophysical properties... 1 fig

    Existing Well UE-10j was deepened and recompleted for the U.S. Department of Energy, Nevada Operations Office in support of the Nevada Environmental Restoration Project at the Nevada Test Site, Nye County, Nevada. The well was originally drilled to a total depth of 725.4 meters in 1965 for use as a hydrologic test hole in the northern portion of Yucca Flat in Area 8 of the Nevada Test Site. The well is located up-gradient of the Yucca Flat underground test area and penetrates deep into the Paleozoic rocks that form the lower carbonate aquifer of the NTS and surrounding areas. The original 24.4-centimeter-diameter borehole was drilled to a depth of 725.4 meters and left uncompleted. Water-level measurements were made periodically by the U.S. Geological Survey, but access to the water table was lost between 1979 and 1981 due to hole sloughing. In 1993, the hole was opened to 44.5 centimeters and cased off to a depth of 670.0 meters. The hole diameter was then decreased to 31.1 centimeters for drilling to a total depth of 796.4 meters. The depth to water in the open borehole was measured at 658.7 meters on March 18, 1993

    Full Text Available Casing drilling is an alternative option to conventional drilling and uses standard oilfield casing instead of drillstring. This technology is one of the greatest developments in drilling operations. Casing drilling involves drilling and casing a well simultaneously. In casing driling process, downhole tools can be retrieved, through the casing on wire-line, meaning tool recovery or replacement of tools can take minutes versus hours under conventional methods. This process employs wireline-retrievable tools and a drill-lock assembly, permitting bit and BHA changes, coring, electrical logging and even directional or horizontal drilling. Once the casing point is reached, the casing is cemented in place without tripping pipe.

Presbycusis is a progressive sensorineural hearing loss that occurs as people get older. There are many studies of the prevalence of age-related hearing loss in the United States, Europe, and Asia. However, no audiological assessment of the population aged 100 years and older has been done. Therefore, it is not clear how well centenarians can hear. We measured middle ear impedance, pure-tone behavioral thresholds, and distortion-product otoacoustic emission from 74 centenarians living in the city of Shaoxing, China, to evaluate their middle and inner ear functions. We show that most centenarian listeners had an "As" type tympanogram, suggesting reduced static compliance of the tympanic membrane. Hearing threshold tests using pure-tone audiometry show that all centenarian subjects had varying degrees of hearing loss. More than 90% suffered from moderate to severe (41 to 80 dB hearing loss below 2,000 Hz, and profound (>81 dB hearing loss at 4,000 and 8,000 Hz. Otoacoustic emission, which is generated by the active process of cochlear outer hair cells, was undetectable in the majority of listeners. Our study shows the extent and severity of hearing loss in the centenarian population and represents the first audiological assessment of their middle and inner ear functions.

    A planar bistable liquid crystal device, reported in Tsakonas, is modeled within the Landau-de Gennes theory for nematic liquid crystals. This planar device consists of an array of square micrometer-sized wells. We obtain six different classes of equilibrium profiles and these profiles are classified as diagonal or rotated solutions. In the strong anchoring case, we propose a Dirichlet boundary condition that mimics the experimentally imposed tangent boundary conditions. In the weak anchoring case, we present a suitable surface energy and study the multiplicity of solutions as a function of the anchoring strength. We find that diagonal solutions exist for all values of the anchoring strength W≥0, while rotated solutions only exist for W≥W c>0, where W c is a critical anchoring strength that has been computed numerically. We propose a dynamic model for the switching mechanisms based on only dielectric effects. For sufficiently strong external electric fields, we numerically demonstrate diagonal-to-rotated and rotated-to-diagonal switching by allowing for variable anchoring strength across the domain boundary. © 2012 American Physical Society.

  3. Cell agglomeration in the wells of a 24-well plate using acoustic streaming.

    Cell agglomeration is essential both to the success of drug testing and to the development of tissue engineering. Here, a MHz-order acoustic wave is used to generate acoustic streaming in the wells of a 24-well plate to drive particle and cell agglomeration. Acoustic streaming is known to manipulate particles in microfluidic devices, and even provide concentration in sessile droplets, but concentration of particles or cells in individual wells has never been shown, principally due to the drag present along the periphery of the fluid in such a well. The agglomeration time for a range of particle sizes suggests that shear-induced migration plays an important role in the agglomeration process. Particles with a diameter of 45 μm agglomerated into a suspended pellet under exposure to 2.134 MHz acoustic waves at 1.5 W in 30 s. Additionally, BT-474 cells also agglomerated as adherent masses at the center bottom of the wells of tissue-culture treated 24-well plates. By switching to low cell binding 24-well plates, the BT-474 cells formed suspended agglomerations that appeared to be spheroids, fully fifteen times larger than any cell agglomerates without the acoustic streaming. In either case, the viability and proliferation of the cells were maintained despite acoustic irradiation and streaming. Intermittent excitation was effective in avoiding temperature excursions, consuming only 75 mW per well on average, presenting a convenient means to form fully three-dimensional cellular masses potentially useful for tissue, cancer, and drug research.

    Full Text Available The growing interest in using Ayurvedic medicine as a gentler, safer option to using modern medicine drugs with attendant side effects continues to be thwarted because claims about effectiveness and safety are not backed with evidence and clinical data. The focus of Ayurveda practice and research should be on building bridges to this knowledge for public benefit. The consumer is being denied basic knowledge, access to product information as well as the benefit of a common prescription written by a single treating physician because of three factors – Ayurvedic OTC medicine is generally sold with names and labels which cannot be understood by the consumer despite being easily available without prescription; the treating modern medicine doctor is being prevented from writing the name of a herbal product even when he is individually convinced about its usefulness (in given circumstances and the absence of biomedical research using objective parameters proving the effectiveness of the drugs. Contemporary Ayurveda needs to be packaged to reach the modern consumer in a way that he gets the benefit of access to treatment options that assist healing within the ambit of the law. These obstacles have to be removed. Patient- based effectiveness studies using retrospective case material as well as research using interdisciplinary approaches are needed for public benefit. This has to be facilitated.

  5. Development of an Improved Cement for Geothermal Wells

    Energy Technology Data Exchange (ETDEWEB)

    Trabits, George [Trabits Group, LLC, Wasilla, AK (United States)

    2015-04-20

    After an oil, gas, or geothermal production well has been drilled, the well must be stabilized with a casing (sections of steel pipe that are joined together) in order to prevent the walls of the well from collapsing. The gap between the casing and the walls of the well is filled with cement, which locks the casing into place. The casing and cementing of geothermal wells is complicated by the harsh conditions of high temperature, high pressure, and a chemical environment (brines with high concentrations of carbon dioxide and sulfuric acid) that degrades conventional Portland cement. During the 1990s and early 2000s, the U.S. Department of Energy’s Geothermal Technologies Office (GTO) provided support for the development of fly-ash-modified calcium aluminate phosphate (CaP) cement, which offers improved resistance to degradation compared with conventional cement. However, the use of CaP cements involves some operational constraints that can increase the cost and complexity of well cementing. In some cases, CaP cements are incompatible with chemical additives that are commonly used to adjust cement setting time. Care must also be taken to ensure that CaP cements do not become contaminated with leftover conventional cement in pumping equipment used in conventional well cementing. With assistance from GTO, Trabits Group, LLC has developed a zeolite-containing cement that performs well in harsh geothermal conditions (thermal stability at temperatures of up to 300°C and resistance to carbonation) and is easy to use (can be easily adjusted with additives and eliminates the need to “sterilize” pumping equipment as with CaP cements). This combination of properties reduces the complexity/cost of well cementing, which will help enable the widespread development of geothermal energy in the United States.

    This is a case study which describes the planning and results of a horizontal well in a shallow Wilcox sandstone waterflood unit in central Louisiana. The Tremont H-13-1 was OXY USA Inc.'s first horizontal well. Analysis will include examination of the selection criteria, planning, execution, completion, and production. A variety of well and field data is presented and reviewed to access the value of this information as it applies towards other applications. The Cruse Waterflood Unit is a 2100 ft. Wilcox formation in central Louisiana. Production improvements have been 500% or greater for the horizontal well versus adjacent vertical wells. The horizontal well paid out in less than 4 months Results from this well indicate that not only was this project an economic success, but that other fields will similar conditions can be produced in a more profitable manner with horizontal wells

    2017-03-01

    Full Text Available This article presents the main options of improved and newly devised designs and process diagrams for installation of foundations made of driven, or jack, piles in the penetrated wells with expanded shoe, mainly in weak wet (waterlogged and water-saturated soils. The article presents six options of process diagrams for installation of driven piles in penetrated wells, listing the main procedures: for well-compacted weak soils, for the case when the water ingress is excluded, for the case when it is necessary to increase the load-bearing capacity of pile's bearing face in the waterlogged soils, for the case when the load-bearing capacity of the pile shall be increased both for the end and for the sides, for the case when peat or other biogenous water-saturated soils are present at the bottom of the well, and for the case when there is no contracted zone nor practical possibility to ensure the stability of the walls. The proposed six options of process diagrams for installation of the driven piles in penetrated wells provide expansion of their area of application regarding the soil conditions, increase of load-bearing capacity, and possibility of using jack systems for driving the piles under conditions of dense urban development.

  8. Principal permeability determination from multiple horizontal well tests

    A method for obtaining principal permeability magnitudes and direction that requires only the linear flow regime from transient tests in three horizontal wells oriented in three distinct and arbitrary directions, is described. Well design optimization strategies require knowledge of both the principal permeability orientation as well as the horizontal permeability magnitudes. When the degree of horizontal permeability anisotropy (i.e. permeability in the bedding plane with respect to direction) is significant, the productivity of a long horizontal well will depend greatly on its direction, especially when the well is first brought into production. Productivities have been found to deviate substantially among wells in the same reservoir and this deviation has been attributed to differences in well orientation. In view of this fact, measuring permeability anisotropy becomes a compelling necessity. The success of the proposed method is illustrated by a case study in which the principal permeability magnitudes and direction from three wells were used to predict the productivity of a fourth well within 10 per cent. Use of the computed principal permeabilities from the case study, it was possible to forecast the cumulative production to show the significance of well trajectory optimization on the discounted cash flow and the net present value. 20 refs., 3 figs.

    This paper is aimed to check the possibility of applying the Steam Assisted Gravity Drainage in vertical wells. This challenge seems to be vital because most of the natural bitumen reservoirs are found to occur above the oil fields being developed so that a well system is already available at the stage of field management. The existing vertical wells are hard to be used for horizontal sidetracking in most of cases as the bitumen reservoir occurs at a shallow depth. The matter is to use the existing wells as vertical ones. At the same time, it is possible to drill an additional sidetrack as a producer or an injector.

    An efficient numerical analytical method has been developed for finding continuum spectrum states in quantum well systems with arbitrary potential profiles that are described by coupled Schroedinger equations. Scattering states and S matrix have been built for the case of multichannel scattering in one-dimensional systems with quantum wells and their symmetry properties are obtained and analyzed. The method is applied for studying hole scattering by strained GaInAs-InGaAsP quantum wells. Coefficients of the hole transmission and reflection as well as delay time are calculated as functions of the energy of the incident hole for various values of parameters of structures and values of the momentum

  13. Approximate approaches to the one-dimensional finite potential well

    International Nuclear Information System (INIS)

    Singh, Shilpi; Pathak, Praveen; Singh, Vijay A

    2011-01-01

    The one-dimensional finite well is a textbook problem. We propose approximate approaches to obtain the energy levels of the well. The finite well is also encountered in semiconductor heterostructures where the carrier mass inside the well (m i ) is taken to be distinct from mass outside (m o ). A relevant parameter is the mass discontinuity ratio β = m i /m o . To correctly account for the mass discontinuity, we apply the BenDaniel-Duke boundary condition. We obtain approximate solutions for two cases: when the well is shallow and when the well is deep. We compare the approximate results with the exact results and find that higher-order approximations are quite robust. For the shallow case, the approximate solution can be expressed in terms of a dimensionless parameter σ l = 2m o V 0 L 2 /ℎ 2 (or σ = β 2 σ l for the deep case). We show that the lowest-order results are related by a duality transform. We also discuss how the energy upscales with L (E∼1/L γ ) and obtain the exponent γ. Exponent γ → 2 when the well is sufficiently deep and β → 1. The ratio of the masses dictates the physics. Our presentation is pedagogical and should be useful to students on a first course on elementary quantum mechanics or low-dimensional semiconductors.

    A linear matrix equation is considered for determining the time dependent wave function for a particle in a one-dimensional infinite square well having one moving wall. By a truncation approximation, whose validity is checked in the exactly solvable case of a linearly contracting wall, we examine the cases of a simple harmonically oscillating wall and a non-harmonically oscillating wall for which the defining parameters can be varied. For the latter case, we examine in closer detail the dependence on the frequency changes, and we find three regimes: an adiabatic behabiour for low frequencies, a periodic one for high frequencies, and a chaotic behaviour for an intermediate range of frequencies.

    Research on the association between physical activity and mental health addresses the beneficial effects of physical activity on emotional and cognitive functioning. With regard to emotional functioning, most studies focus on the influence of physical activity on depressive symptoms or affective disorders. These studies show that the beneficial effects of aerobic exercise and pharmacotherapy on depressive symptoms seem to be comparable and discuss a variety of neurobiological mechanisms that improve symptoms. The positive effects of physical activity on anxious mood and anxiety disorders are also well documented. Desensitization to physiological changes, improved self-esteem, and self-efficacy seem to play an important part. However, aerobic exercise does not improve mental health in every case, as seen for instance in over-trained athletes. Research on the relationship between physical activity and cognitive functioning reveals that physical activity can prevent the age-related cognitive decline and can delay the onset of dementia. Physical activity has beneficial effects not only on adults but also on children's and adolescents' mental health and cognitive performance, particularly on their executive functions that are still developing throughout adolescence. Finally, physical activity also affects the endocrine stress-regulation system: trained people reveal stronger reactivity and quicker regeneration when faced with stressful events.

    More than 10 million wells have been drilled during 150 years of oil and gas production in the United States. When abandoned, many wells were not adequately sealed and now provide a potential conduit for the vertical movement of liquids and gases. Today, groundwater aquifers can be contaminated by surface pollutants flowing down wells or by deep, saline water diffusing upwards. Likewise, natural gas, carbon dioxide (CO2), or radon can travel upwards via these wells to endanger structures or human health on the surface. Recently, the need to find and plug wells has become critical with the advent of carbon dioxide injection into geologic formations for enhanced oil recovery (EOR) or carbon storage. The potential for natural gas or brine leakage through existing wells has also been raised as a concern in regions where shale resources are hydraulically fractured for hydrocarbon recovery. In this study, the National Energy Technology Laboratory (NETL) updated existing, effective well finding techniques to be able to survey large areas quickly using helicopter or ground-vehicle-mounted magnetometers, combined with mobile methane detection. For this study, magnetic data were collected using airborne and ground vehicles equipped with two boom-mounted magnetometers, or on foot using a hand-held magnetometer with a single sensor. Data processing techniques were employed to accentuate well-casing-type magnetic signatures. To locate wells with no magnetic signature (wells where the steel well casing had been removed), the team monitored for anomalous concentrations of methane, which could indicate migration of volatile compounds from deeper sedimentary strata along a well or fracture pathway. Methane measurements were obtained using the ALPIS DIfferential Absorption Lidar (DIAL) sensor for helicopter surveys and the Apogee leak detection system (LDS) for ground surveys. These methods were evaluated at a 100-year-old oilfield in Wyoming, where a helicopter magnetic

  18. Promoting the management and protection of private water wells.

    Science.gov (United States)

    Simpson, Hugh

    Rural families in Ontario depend almost entirely on groundwater from private wells for their potable water supply. In many cases, groundwater may be the only feasible water supply source and it requires management and protection. A significant potential source of ground water contamination is the movement of contaminated surface water through water wells that are improperly constructed, maintained, or should be decommissioned. Therefore, proper water well construction and maintenance, and eventual decommissioning, are critical for managing and protecting the quantity and quality of groundwater, as well as ensuring the integrity of rural drinking-water supplies. These actions are important for protecting private water supplies from both potential human and natural contamination. Individual well owners each have a personal interest and valuable role in ensuring the integrity of their water supplies. The following information is required to help well owners ensure the integrity of their water supply: different types of wells, why some wells are at greater risk of contamination than others, and sources of groundwater contaminants; groundwater contaminants, how they can move through soil and water, and potential risks to human health; benefits of ensuring that wells are properly maintained and operate efficiently; and importance of a regular well water quality testing program. This paper summarizes the technical information that should be provided to rural well owners concerning proper water well and groundwater management and protection, and provides an example of how this information can be promoted in an effective manner.

In this study, the National Energy Technology Laboratory (NETL) updated existing, effective well finding techniques to be able to survey large areas quickly using helicopter or ground-vehicle-mounted magnetometers, combined with mobile methane detection. For this study, magnetic data were collected using airborne and ground vehicles equipped with two boom-mounted magnetometers, or on foot using a hand-held magnetometer with a single sensor. Data processing techniques were employed to accentuate well-casing-type magnetic signatures. To locate wells with no magnetic signature (wells where the steel well casing had been removed), the team monitored for anomalous concentrations of methane, which could indicate migration of volatile compounds from deeper sedimentary strata along a well or fracture pathway. Methane measurements were obtained using the ALPIS DIfferential Absorption Lidar (DIAL) sensor for helicopter surveys and the Apogee leak detection system (LDS) for ground surveys. These methods were evaluated at a 100-year-old oilfield in Wyoming, where a helicopter magnetic survey accurately located 93% of visible wells. In addition, 20% of the wells found by the survey were

    When estimating the time since death or manner of death, the identification and the pathological evaluations of a body are generally impeded by post mortem changes. Research and case studies help experts to achieve a more accurate diagnosis, but at present there is scant literature covering topics concerning forensic science and decompositional processes in aquatic environments. The two case studies presented each involve a decomposed body found in a unique aquatic environment; namely wells containing ground water. In Case 1 an entomologist attended the scene and in Case 2 an entomologist was only involved after 20 months when it was decided that the insect evidence collected at the second autopsy may be useful in determining a time frame. The first case highlights the problems associated with body retrieval from aquatic environments as the body was removed it dismembered. Fortunately, the well was able to be drained, so much of the insect evidence was retrieved. In the second case the body was found dismembered but the entomological evidence was overlooked and lost. During the second autopsy insects were found, collected, and sent to an entomologist to help clarify the post mortem interval.

    Fibromyalgia syndrome (FMS) is a common rheumatologic disorder characterized by easy fatigability, widespread musculoskeletal pain and sleep disorder. In spite of its high prevalence, general practitioners, as primary care providers, seem to have inadequate knowledge about FMS. This study aimed to assess Iranian general practitioners' knowledge about FMS and its treatment. A detailed questionnaire (including items on signs and symptoms, diagnostic criteria and treatment) was completed by 190 general practitioners (54.7% male; mean age: 41 years). Data analysis was performed with SPSS for Windows 15.0 and awareness about all aspects of FMS was reported as percentages. About one-third (30%) of the participants had seen at least one case of FMS during their practice. Most subjects (62.7%) claimed to know 1-6 tender points. Only 3.2% knew 16-18 points. The common proposed symptoms of FMS were widespread pain (72.6%), excessive fatigue (72.6%), weakness (60.5%), sleep disorder (36.3%), anxiety (34.7%) and depression (34.2%). Wrong symptoms including elevated erythrocyte sedimentation rate and C-reactive protein, arthritis, joint swelling, weight loss and abnormal radiologic findings were selected by 27.9%, 18.9%, 14.7%, 12.6% and 2.1% of the physicians, respectively. Moreover, selective serotonin reuptake inhibitors, tricyclic antidepressant and pregabalin were identified as treatment options for FMS by, respectively, 45.8%, 22.1% and 15.3% of the participants. Finally, 52.1% and 23.7% of the subjects incorrectly considered nonsteroidal anti-inflammatory drugs and corticosteroids as treatment modalities for FMS. Iranian general practitioners are not well informed about FMS. Therefore, FMS should be specifically integrated in continuing medical education programs and undergraduate medical training curriculum. © 2015 Asia Pacific League of Associations for Rheumatology and Wiley Publishing Asia Pty Ltd.

  6. Huygens is alive and well, in space

    "It all went very smoothly, " said Jonh Dodsworth, ESOC's flight operations Director, "We had the option to continue checks on 26 October in case of difficulty, but we don't need to. That's good news". ESOC established connection with the Huygens probe at 10:09 hrs, Central European Time on 23 October, using NASA's link to Cassini. Thanks to ESOC's new flight operations system, engineers and scientists responsible for the mission could check quite quickly that Huygens is alive and well in all respects. ESA's project management team, and representatives of the contractors who built Huygens, were able to report that the engineering system and subsystems are all performing nominally. The principal investigators from Europe and the USA, in charge of the six instruments on Huygens, were also present for the tests. Each experiment was checked for functionality : * HASI to analyse Titan's atmosphere and weather - DWE to measure wind speeds during the descent - GCMS to analyse chemical compounds on Titan - ACP to break down aerosols for chemical analysis - DISR to produce images and spectra of Titan - SSP to determine the nature of Titan's surface. "Six experiments, six green lights", said Jean-Pierre Lebreton, ESA's project scientist. The project manager for Huygens is Hamid Hassan. In Darmstadt he too declared himself pleased with the check-out of the Huygens systems, subsystems and instruments. "We will now let Huygens go back to sleep, except for the planned six monthly checkouts" Hassan said. "The probe will remain in that condition for the seven-year journey to Saturn. But we now have every reason to expect a successful outcome to this unprecedented mission".

  7. New method of analyzing well tests in fractured wells using sandface pressure and rate data

    Analysis of variable flow rate tests has been of special interest recently because in many cases it is impractical to keep a flow rate constant long enough to perform a drawdown test. Further, in many other drawdown and buildup tests, the early data were influenced by wellbore storage effects, and the duration of these effects could be quite long for low-permeability reservoirs. This paper presents a mathematical model which describes drawdown and buildup tests in hydraulically fractured wells. This new method uses a specialized plot approach to analyze the linear flow data and combines it with the superposition of constant-rate solution method for the analysis of psuedoradial flow data. It does not require prior knowledge of the fracture type (uniform-flux or infinite-conductivity); in fact it predicts the fracture type. This method is useful for the analysis of simultaneously measured downhole pressure and sandface rate data. 12 refs., 11 figs., 3 tabs.

    Improved methods for the prediction, evaluation, and monitoring of performance in high-rate cased-hole gravel-packed oil wells are presented in this thesis. The ability to predict well performance prior to the gravel-pack operations, evaluate the results after the operation, and monitor well performance over time has been improved. This lifetime approach to performance analysis of gravel-packed oil wells contributes to increase oil production and field profitability. First, analytical models available for prediction of performance in gravel-packed oil wells are reviewed, with particular emphasis on high-velocity flow effects. From the analysis of field data from three North Sea oil fields, improved and calibrated cased-hole gravel-pack performance prediction models are presented. The recommended model is based on serial flow through formation sand and gravel in the perforation tunnels. In addition, new correlations for high-velocity flow in high-rate gravel-packed oil wells are introduced. Combined, this improves the performance prediction for gravel-packed oil wells, and specific areas can be targeted for optimized well design. Next, limitations in the current methods and alternative methods for evaluation and comparison of well performance are presented. The most widely used parameter, the skin factor, remains a convenient and important parameter. However, using the skin concept in direct comparisons between wells with different reservoir properties may result in misleading or even invalid conclusions. A discussion of the parameters affecting the skin value, with a clarification of limitations, is included. A methodology for evaluation and comparison of gravel-packed well performance is presented, and this includes the use of results from production logs and the use of effective perforation tunnel permeability as a parameter. This contributes to optimized operational procedures from well to well and from field to field. Finally, the data sources available for

    Drainage wells are used to inject surface waters directly into an aquifer, or shallow ground waters directly into a deeper aquifer, primarily by gravity. Such wells in Florida may be grouped into two broad types: (1) surface-water injection wells, and (2) interaquifer connector wells. Drainage wells of the first type are further categorized as either Floridan aquifer drainage wells or Biscayne aquifer drainage wells. Floridan aquifer drainage wells are commonly used to supplement drainage for urban areas in karst terranes of central and north Florida. Data are available for 25 wells in the Ocala, Live Oak, and Orlando areas that allow comparison of the quality of water samples from these Floridan aquifer drainage wells with allowable contaminant levels. Comparison indicates that maximum contaminant levels for turbidity, color, and iron, manganese, and lead concentrations are equaled or exceeded in some drainage-well samples, and relatively high counts for coliform bacteria are present in most wells. Biscayne aquifer drainage wells are used locally to dispose of stormwater runoff and other surplus water in southeast Florida, where large numbers of these wells have been permitted in Dade and Broward Counties. The majority of these wells are used to dispose of water from swimming pools or to dispose of heated water from air-conditioning units. The use of Biscayne aquifer drainage wells may have minimal effect on aquifer potability so long as injection of runoff and industrial wates is restricted to zones where chloride concentrations exceed 1,500 milligrams per liter. Interaquifer connector wells are used in the phosphate mining areas of Polk and Hillsborough Counties, to drain mines and recharge the Floridan aquifer. Water-quality data available from 13 connector wells indicate that samples from most of these wells exceed standards values for iron concentration and turbidity. One well yielded a highly mineralized water, and samples from 6 of the other 12 wells exceed

    overlooked as it is usually several years down the road from their first publication. In order for case reports or case series to have an impact, it is critical that they move the field forward and/or provide an educational component. For these reasons, the editors of AJP Reports will look for evidence of the following qualifications when evaluating case reports or case series: 1. The report describes a novel test or procedure, or novel application of an established test or procedure. 2. The case reports a rare condition or complication, and includes an imbedded lesson. The emphasis is on the latter. If it is a report of some condition that has not been adequately reported in pregnancy or in the neonate, but is otherwise well described in non-pregnant women or adults, then it is important that the report provides novel insight into how the condition in the context of pregnancy or immediate postnatal period differs from what has been reported in the general population. The mere fact that it has not been adequately reported in pregnancy or the neonate cannot be the sole reason for publication. Obviously this criterion may be relaxed if this is the first report ever of such a condition or complication. 3. The case reported may be used as a springboard for a review of the condition and its management. In that case, the emphasis is on the review, which has to be informative. The judgment here will be based mostly on the quality of the review and its impact on dissemination of knowledge. I would like to close by asking for your support of this new journal. Our goal is to provide our readers with useful information. As with every new endeavor, I ask for your patience and comments as we make it better. Do not hesitate to contact me or Dr. Higgins with any questions or comments. In the meantime, keep the cases coming.

    This paper reports that operators of marginal oil and gas wells often can avoid having to shut them in by compressing gas from the back side of the casing at the well head and delivering it into the flowline. This process can reduce the back pressure at the face of the producing formation, which allows additional oil and gas to be produced and extends the economical reserves. Small, low-horsepower stationary compressors or a walking beam compressor (WBC) may be used for this purpose. A portable compressor test unit recently has been employed to evaluate wells that are possible candidates for wellhead compression as another cost cutting measure

    To examine health insurance companies' role in employee wellness. Case studies of eight insurers. Wellness activities in work, clinical, online, and telephonic settings. Senior executives and wellness program leaders from Blue Cross Blue Shield health insurers and from one wellness organization. Telephone interviews with 20 informants. Health insurers were engaged in wellness as part of their mission to promote health and reduce health care costs. Program components included the following: education, health risk assessments, incentives, coaching, environmental consultation, targeted programming, onsite biometric screening, professional support, and full-time wellness staff. Programs relied almost exclusively on positive incentives to encourage participation. Results included participation rates as high as 90%, return on investment ranging from $1.09 to $1.65, and improved health outcomes. Health insurers have expertise in developing, implementing, and marketing health programs and have wide access to employers and their employees' health data. These capabilities make health insurers particularly well equipped to expand the reach of wellness programming to improve the health of many Americans. By coupling members' medical data with wellness-program data, health insurers can better understand an individual's health status to develop and deliver targeted interventions. Through program evaluation, health insurers can also contribute to the limited but growing evidence base on employee wellness programs.

    U.S. Strategic Petroleum Reserve (SPR) oil storage cavern West Hackberry 117 was tested under extended nitrogen monitoring following a successful mechanical integrity test in order to validate a newly developed hydrostatic column model to be used to differentiate between normal "tight" well behavior and small-leak behavior under nitrogen. High resolution wireline pressure and temperature data were collected during the test period and used in conjunction with the hydrostatic column model to predict the nitrogen/oil interface and the pressure along the entire fluid column from the bradenhead flange nominally at ground surface to bottom of brine pool. Results here and for other SPR caverns have shown that wells under long term nitrogen monitoring do not necessarily pressurize with a relative rate (P N2 /P brine) of 1. The theoretical relative pressure rate depends on the well configuration, pressure and the location of the nitrogen-oil interface and varies from well to well. For the case of WH117 the predicted rates were 0.73 for well A and 0.92 for well B. The measured relative pressurization rate for well B was consistent with the model prediction, while well A rate was found to be between 0.58-0.68. A number of possible reasons for the discrepancy between the model and measured rates of well A are possible. These include modeling inaccuracy, measurement inaccuracy or the possibility of the presence of a very small leak (below the latest calculated minimum detectable leak rate).

  19. Meaning shift: findings from wellness acupuncture.

    2006-01-01

    Wellness or holistic acupuncture places an emphasis on working with and developing the patient's understanding of health and illness. This research project examines changes in meaning in 367 letters from successful wellness acupuncture. Mentions of changes of the meaning of health and illness were categorized into themes using content analysis. Five main meaning shifts were identified in the data. These shifts are (1) from a goal of fixing the problem to a goal of increasing health, (2) from symptoms as problems to symptoms as teachers, (3) from healing as passive to healing as active, (4) from being dominated by illness to moving beyond the illness, and (5) from regarding the practitioner as a technician to regarding the practitioner as a healer or friend. The shifts in meaning seen in the data illustrate a potential pathway for bringing health benefits to patients and may provide a useful strategy for healing. Narrative (defined here as "first-person accounts by respondents of their experience") is thought to play a major role in the manifestation of symptoms and the ability of patients to cope with illness. Patients suffer not only from their primary symptoms, but also from the results and effects of their illnesses, such as depression and changes in their relationships. For the patient, symptoms often hold much meaning beyond physical sensation. A recurrence of symptoms can have other unpleasant results, such as additional trips to doctors, paying for medications, time off from work, not being able to play with children, or changes in relationships with family members. In many cases, the anxiety and depression surrounding the symptoms causes suffering which are greater than the suffering caused by the physical symptoms directly. These factors also change how the ill individual interacts socially, thereby reducing both instrumental and emotional social support, resulting in a downward spiral of suffering. By interacting with narrative, a path to improved health

    1993-01-01

    Shallow injection wells have long been used for disposing liquid wastes. Some of these wells have received hazardous or radioactive wastes. According to US Environmental Protection Agency (EPA) regulations, Class IV wells are those injection wells through which hazardous or radioactive wastes are injected into or above an underground source of drinking water (USDW). These wells must be closed. Generally Class V wells are injection wells through which fluids that do not contain hazardous or radioactive wastes are injected into or above a USDW. Class V wells that are responsible for violations of drinking water regulations or that pose a threat to human health must also be closed. Although EPA regulations require closure of certain types of shallow injection wells, they do not provide specific details on the closure process. This paper describes the regulatory background, DOE requirements, and the steps in a shallow injection well closure process: Identification of wells needing closure; monitoring and disposal of accumulated substances; filling and sealing of wells; and remediation. In addition, the paper describes a major national EPA shallow injection well enforcement initiative, including closure plan guidance for wells used to dispose of wastes from service station operations

    Well testing is one of the most widely used tools to characterize reservoirs throughout the entire life of petroleum exploration and production. In this study, we first try to set up a procedure of computer aided well test analysis and then attempt to characterize potential reservoirs by performing well test analysis for some of the exploratory wells in the Korean continental shelf. A couple of gas well testing data already published in the literature were also analyzed and compared. First task was to analyze the drill stem test(DST) in KCS-1 gas well. The second analysis was also DST data on multi-rate gas wells. The third case is a Devonian shale reservoir. The final problem is a multi-rate drawdown test without early time pressure data. It is now possible to analyze insufficient well test data with less accuracy. One remark should be pointed out on multi-rate gas well testing. It is recommended to have variable skins rather than a constant skin because rate dependent skins due to turbulence of gas flow must be considered in addition to the mechanical skin.

    2017-10-01

    Declining groundwater levels are common in parts of the western US, but their impact on the ability of wells to pump groundwater is not known. Here we collate groundwater well records for the western United States and present the recorded locations, depths, and purposes of more than two million groundwater wells constructed between 1950 and 2015. We then use the well records to estimate the percentage of wells that were dry during the years 2013-2015. During the two year period, dry wells were concentrated in rural areas with high agricultural productivity, such as parts of the California Central Valley and the High Plains. Our results support anecdotal evidence that wells used for domestic purposes are more susceptible to drying than wells used for agricultural purposes throughout California’s Central Valley because the former tend to be shallower. However, this is not the case in all regions. Our findings suggest that declining groundwater levels are threatening drinking water reliability and agricultural productivity, and consequently, have key implications for both domestic and agricultural water security. Ongoing reductions to groundwater storage are drying groundwater wells in the western US, and this manifestation of water scarcity warrants innovative groundwater management transcending status quos.

    In a drinking water well in Nethen, Germany, a yellowish precipitate, dominated by aluminum and phosphorus, affected the operation of the submersible pump by mechanically blocking the impellers. So far, aluminum-dominated well incrustations have been documented in only two cases and their mineralogical characterization was insufficient. The aim of the present study is to (1) present a third finding of Al-incrustations in wells, (2) provide a mineralogical and geochemical in-depth characterization of the precipitate, and (3) try to explain the reason for the problems it causes for drinking water production from this well. The yellow precipitate consists of nanoparticle aggregates and is a short-range ordered phase that could be described as a modified form of evansite with phosphate being the major anion, accompanied by some sulfate and carbonate. Additionally, aggregation with hydrous silicates and organic material is present, which could be simply adsorbed or co-precipitated. The precipitate formed as shallow acidic groundwater containing dissolved aluminum entered the well through a leaky casing seal. In the well it mixed with deeper groundwater of higher pH, causing Al-phosphate precipitations. The aggregates tended to accumulate at the entrance slots of the pump which therefore became blocked and had to be replaced.

    The Department of Energy (DOE) is sponsoring a Deep Trek Program targeted at improving the economics of drilling and completing deep gas wells. Under the DOE program, Pinnacle Technologies is conducting a project to evaluate the stimulation of deep wells. The objective of the project is to assess U.S. deep well drilling & stimulation activity, review rock mechanics & fracture growth in deep, high pressure/temperature wells and evaluate stimulation technology in several key deep plays. Phase 1 was recently completed and consisted of assessing deep gas well drilling activity (1995-2007) and an industry survey on deep gas well stimulation practices by region. Of the 29,000 oil, gas and dry holes drilled in 2002, about 300 were drilled in the deep well; 25% were dry, 50% were high temperature/high pressure completions and 25% were simply deep completions. South Texas has about 30% of these wells, Oklahoma 20%, Gulf of Mexico Shelf 15% and the Gulf Coast about 15%. The Rockies represent only 2% of deep drilling. Of the 60 operators who drill deep and HTHP wells, the top 20 drill almost 80% of the wells. Six operators drill half the U.S. deep wells. Deep drilling peaked at 425 wells in 1998 and fell to 250 in 1999. Drilling is expected to rise through 2004 after which drilling should cycle down as overall drilling declines.

    The purpose of this study was to evaluate the MRI findings of well-differentiated liposarcoma. Ten well-differentiated liposarcomas surgically excised with histologic diagnosis were included in this study. The subjects consisted of five men and five women, with an average age of 62.5 years (range: 43-79 years). Six cases occurred in the thigh, two in the forearm, one in the shoulder, and one in the chest wall. Thickened septa (generally ≥2 mm) of low T1 signal and high T2 signal, and prominent area of enhancement were suspicious for well-differentiated liposarcoma. So we checked these lesions and compared with the pathologic findings of these lesions. Thick septa and prominent area of enhancement were identified in all cases except one case who could not use Gadolinium. Pathologically, these lesions were composed of a relatively mature adipocytic proliferation in which, in contrast to benign lipoma, significant variation in cell size is easily appreciable. So we consider that thick septa and prominent area of enhancement are evidently suspicious lesions for well-differentiated liposarcoma. (author)

    2007-01-01

    Full text: Well-differentiated thyroid cancer (DTCA) in children is quite different from the adult- onset disease in that they are more aggressive at the time of diagnosis and with metastases and has a higher risk for recurrence. Some studies claim it to be less lethal and hence treatment protocols may be different from that of the adult. This study was made to analyze the need for RAI therapy as one of the cornerstone of treatment aside from surgery and thyroid hormone suppression as well as to determine the behavior of WDTCA in children. Results: The incidence of DTCA is varied and ranges from 1-10% in several published series. In the Philippines where thyroid cancer in adults ranks 5th in mortality for both sexes, the incidence is likewise very low, around 0.5-1% for ages 18 years and below in a ten year study. It was predominantly a female population (74%) as compared to the males (26%). Fifteen cases were reviewed and included as most were given RAI (87%). Most presented as a solitary nodule and with lymph node metastases. Thirteen cases were papillary in nature and only two cases were follicular. The incidence of nodal metastases was 53% while lung metastases were seen in 20% of cases. Of the 13 cases that underwent RAI therapy, three cases of lung metastases needed repeat therapy. In the cases with lymph node metastases, 2 cases also had recurrence and which necessitated repeat RAI therapy. The two cases that did not get RAI therapy had progressive disease on follow- up after 5 and 7 years respectively from surgery. Discussion: Primary treatment for DTC should consist of surgery, radioiodine ablation and thyroid hormone suppression. We must rely on pediatric outcome studies and the high frequency of multifocal intrathyroidal disease, loco- regional spread and extra cervical metastases often seen as initial presentations of this particular group. The more advanced disease at diagnosis for children, propensity for recurrence as well as the greater radioiodine

    Giving recommended immunizations during sick visits for minor and acute illness such as acute otitis media has long been an American Academy of Pediatrics/Advisory Committee on Immunization Practice recommendation. An addition to the American Academy of Pediatrics policy in 2010 advised considering whether giving immunizations at the sick visit would discourage making up missed well-baby visits. This study quantifies the potential tradeoff between sick-visit immunizations and well-baby visits. This study was a retrospective cohort analysis with a case-control component of sick visits for acute otitis media that supplanted normal well-baby visits at age 2, 4, or 6 months. Infants were stratified for sick-visit immunization, no sick-visit immunization but quick makeup well-baby visits, or no sick-visit immunizations or quick makeup visits. Immunization rates and well-baby visit rates were assessed through 24 months of age. For 1060 study cases, no significant difference was detected in immunization rates or well-baby visits through 24 months of age between those with or without sick-visit immunizations. Thirty-nine percent of infants without a sick-visit shot failed to return for a quick makeup well-baby visit; this delayed group was significantly less likely to be up-to-date for immunizations (relative risk: 0.66) and had fewer well-baby visits (mean: 3.8) from 2 through 24 months of age compared with those with sick-visit shots (mean: 4.7). The substantial risk that infants will not return for a timely makeup well-baby visit after a sick visit should be included in any consideration of whether to delay immunizations.

    1985-01-01

    Recently, 50 dry wells were constructed at the Idaho Chemical Processing Plant (ICPP) to temporarily store the Light Water Breeder Reactor (LWBR) fuel. Over 400 dry wells of the same design are projected to be constructed in the next 5 yr at the ICPP to store unreprocessible fuels until a permanent repository becomes available. This summary describes the LWBR fuel storage dry wells and the enhancements made over the Peach Bottom fuel and Fermi blanket dry wells that have been in use for up to 4 yr. Dry well storage at the ICPP has historically been found to be a safe and efficient method of temporary fuel storage. The LWBR dry wells should be more reliable than the original dry wells and provide data not previously available

    A total of 15 water-supply wells are currently being used at the Nevada Test Site (NTS). The purpose of this report is to bring together the information gleaned from investigations of these water-supply wells. This report should serve as a reference on well construction and completion, static water levels, lithologic and hydrologic characteristics of aquifers penetrated, and general water quality of water-supply wells at the NTS. Possible sources for contamination of the water-supply wells are also evaluated. Existing wells and underground nuclear tests conducted near (within 25 meters (m)) or below the water table within 2 kilometers (km) of a water-supply were located and their hydrogeologic relationship to the water-supply well determined

    Academic research on well-being is pursued in multiple disciplines and currently exploding. Governments are also interested in the topic, as witnessed by their recent efforts to develop statistical measures of progress that include well-being indicators. Combined, this interest opens the door...... to the fruitful application of well-being research to society. Research on well-being, however, is not always well integrated across the disciplines that purport to study it. In particular, there is insufficient communication between the empirical study of well-being, and its normative/conceptual study as pursued...... in philosophy. This state of affairs is lamentable, as it robs science and public policy of the expertise of philosophers, a desirable tool when evaluating empirical claims about well-being promotion. In this article, I examine the reasons for this lack of communication. In particular, I reject the view...

    Full Text Available Introduction: Cephalohematoma is a collection of serosanguineous fluid below the periosteum and is the most frequent cranial injury in the newborn, occurring in 0.2-2.5% live births. The majority of cephalohematomas spontaneously resolve within three to four weeks, however, some persist beyond four weeks and begin to calcify. Case report: A seven-week-old boy, was referred to the emergency department because of a head lump on the right parietal region, with no other symptoms. He was born after a vacuum-assisted delivery, and presented a cephalohematoma in the first days of life, that progressively decreased and became more rigid. Physical examination, revealed a cranial asymmetry, and a head lump on the right parietal region, that was hard and fixed to the bone. Head X-ray revealed a radiopaque lump on the right parietal bone and a poorly defined arched line, as well as visible microcalcifications on the core of the cephalohematoma, typical findings of a calcified cephalohematoma. Discussion: Even though cephalohematoma is frequently encountered, calcified cephalohematoma is seen only sporadically, and is a rare clinical entity. History and clinical examination are important in the differential diagnosis and imaging strategy. Radiography and ultrasonography are often the initial screening diagnostic tests, followed by magnetic resonance imaging or computed tomography. Head x-ray features, in this case report, where particularly evocative of the diagnosis.

  19. Potential hydrologic characterization wells in Amargosa Valley

    International Nuclear Information System (INIS)

    Lyles, B.; Mihevc, T.

    1994-09-01

    More than 500 domestic, agricultural, and monitoring wells were identified in the Amargosa Valley. From this list, 80 wells were identified as potential hydrologic characterization wells, in support of the US Department of Energy (DOE) Underground Test Area/Remedial Investigation and Feasibility Study (UGTA/RIFS). Previous hydrogeologic studies have shown that groundwater flow in the basin is complex and that aquifers may have little lateral continuity. Wells located more than 10 km or so from the Nevada Test Site (NTS) boundary may yield data that are difficult to correlate to sources from the NTS. Also, monitoring well locations should be chosen within the guidelines of a hydrologic conceptual model and monitoring plan. Since these do not exist at this time, recompletion recommendations will be restricted to wells relatively close (approximately 20 km) to the NTS boundary. Recompletion recommendations were made for two abandoned agricultural irrigation wells near the town of Amargosa Valley (previously Lathrop Wells), for two abandoned wildcat oil wells about 10 km southwest of Amargosa Valley, and for Test Well 5 (TW-5), about 10 km east of Amargosa Valley

    In 1919, the enthusiasm surrounding a short-lived gas play in Versailles Borough, Pennsylvania resulted in the drilling of many needless wells. The legacy of this activity exists today in the form of abandoned, unplugged gas wells that are a continuing source of fugitive methane in the midst of a residential and commercial area. Flammable concentrations of methane have been detected near building foundations, which have forced people from their homes and businesses until methane concentrations decreased. Despite mitigation efforts, methane problems persist and have caused some buildings to be permanently abandoned and demolished. This paper describes the use of magnetic and methane sensing methods by the National Energy Technology Laboratory (NETL) to locate abandoned gas wells in Versailles Borough where site access is limited and existing infrastructure can interfere. Here, wells are located between closely spaced houses and beneath buildings and parking lots. Wells are seldom visible, often because wellheads and internal casing strings have been removed, and external casing has been cut off below ground level. The magnetic survey of Versailles Borough identified 53 strong, monopole magnetic anomalies that are presumed to indicate the locations of steel-cased wells. This hypothesis was tested by excavating the location of one strong, monopole magnetic anomaly that was within an area of anomalous methane concentrations. The excavation uncovered an unplugged gas well that was within 0.2 m of the location of the maximum magnetic signal. Truck-mounted methane surveys of Versailles Borough detected numerous methane anomalies that were useful for narrowing search areas. Methane sources identified during truck-mounted surveys included strong methane sources such as sewers and methane mitigation vents. However, inconsistent wind direction and speed, especially between buildings, made locating weaker methane sources (such as leaking wells) difficult. Walking surveys with

    Meticulous planning and careful control of operations are needed to safely drill and test high-temperature, high-pressure (HTHP) wells. Techniques, employed in the Central Graben in the UK sector of the North Sea, where about 50 HTHP wells have been drilled, are examined. Three main areas of activity are covered in this comprehensive review: drilling safety, casing and cementation, and testing. The three issues at the heart of HTHP drilling safety are kick prevention, kick detection and well control. Kicks are influxes of reservoir fluid into the well. Test equipment and operations are divided into three sections: downhole, subsea and surface. Also details are given of how this North Sea experience has been used to help plan a jackup rig modification for hot, high-pressure drilling off Brunei. 16 figs., 32 refs.

  6. Productivity and injectivity of horizontal wells

    Energy Technology Data Exchange (ETDEWEB)

    Aziz, Khalid

    2000-03-06

    One of the key issues addressed was pressure drop in long horizontal wells and its influence on well performance. Very little information is available in the literature on flow in pipes with influx through pipe walls. Virtually all of this work has been in small diameter pipes and with single-phase flow. In order to address this problem new experimental data on flow in horizontal and near horizontal wells have been obtained. Experiments were conducted at an industrial facility on typical 6 1/8 ID, 100 feet long horizontal well model. The new data along with available information in the literature have been used to develop new correlations and mechanistic models. Thus it is now possible to predict, within reasonable accuracy, the effect of influx through the well on pressure drop in the well.

    The choice of treatment for a well-differentiated carcinoma (WDC) of the thyroid has remained controversial for several decades. This is unfortunate because WDC occurs in the young, particularly in women, and is compatible with several years of survival. A retrospective analysis of 417 cases of WDC of the thyroid treated by definitive surgery at the Tata Memorial Hospital for the 15-year period (1970 to 1985) form the basis of the conclusion drawn in the present report. These include cases that were referred primarily and those who underwent revision or completion thyroidectomy at the hospital after being treated elsewhere. All relevant data of the cases with WDC, including histopathology slides, were reviewed by an experienced pathologist

    A well completion scheme currently in use in a thick, large, elongated carbonate anticline Middle-East oil reservoir is described. This method of well completion calls for a combination of an open hole horizontal section penetrating the top 10 feet of the reservoir and a cased or undisturbed vertical segment through the thick formation. The horizontal section is used for producing and the vertical segment is used for monitoring purposes. Field experience and supported reservoir simulation exercises have shown that the horizontal application is superior to conventional vertical completion both from the economic and from the sweep point of view. 4 refs., 12 figs.

    We present ANAPPRES V1.0, the first version of a computerized expert system capable of analyzing constant- and variable-flowrate interference tests, in which there is one active well and an arbitrary number of observation wells, in liquid-saturated homogeneous reservoirs. ANAPPRES successfully couples mathematical models, optimization techniques, heuristic knowledge and computerized graphics, a combination not often found in published expert systems. Its main advantages are that it is user friendly, requires essentially no experience on the part of the analyst, eliminates subjectivity associated with earlier techniques of analysis, can handle complex cases and large data sets, completes the analysis of even the most complex cases (including plotting the results) in one run, and is significantly faster than a human expert.

This was an employer case study evaluation of well-being, productivity (presenteeism, absenteeism, and job performance), health risk, and employer support across three employee assessment spanning 2 years. Employee well-being was compared with an independent sample of workers in the community. Well-being and job performance increased and presenteeism and health risk decreased significantly over the 2 years. Employee well-being started lower and increased to exceed community worker averages, approaching significance. Well-being improvement was associated with higher productivity across all measures. Increases in employer support for well-being were associated with improved well-being and productivity. This employer's well-being strategy, including a culture supporting well-being, was associated with improved health and productivity.

    We theoretically investigate the spin splitting in four undoped asymmetric quantum wells in the absence of external electric field and magnetic field. The quantum well geometry dependence of spin splitting is studied with the Rashba and the Dresselhaus spin-orbit coupling included. The results show that the structure of quantum well plays an important role in spin splitting. The Rashba and the Dresselhaus spin splitting in four asymmetric quantum wells are quite different. The origin of the distinction is discussed in this work. (condensed matter: electronic structure, electrical, magnetic, and optical properties)

    This report provides analytical results for groundwater collected during four characterization-sampling rounds conducted at well R-22 from March 2001 through March 2002. Characterization well R-22 was sampled from March 6 through 13, 2001; June 19 through 26, 2001; November 30 through December 10, 2001; and February 27 through March 7, 2002. The goal of the characterization efforts was to assess the hydrochemistry and to determine whether or not contaminants are present in the regional aquifer in the vicinity of the well. A geochemical evaluation of the analytical results for the well is also presented in this report

    Surface states are studied in dependence on thickness or organic quantum wells within the nearest layer approximation. It is shown that there is a material-dependent critical thickness. Structures, that have thickness thinner or thicker than the critical one, exhibit qualitatively different characteristics of surface states. Criteria for existence and sign rules for location of energy levels of surface states are established which are general and contain the results of the previous works as particular cases.

    The no-type curve with negative skin of a horizontal well has been found in the current research. Negative skin is very significant to transient well test and rate decline analysis. This paper first presents the negative skin problem where the type curves with negative skin of a horizontal well are oscillatory. In order to solve the problem, we propose a new model of transient well test and rate decline analysis for a horizontal well in a multiple-zone composite reservoir. A new dimensionless definition of r D is introduced in the dimensionless mathematical modelling under different boundaries. The model is solved using the Laplace transform and separation of variables techniques. In Laplace space, the solutions for both constant rate production and constant wellbore pressure production are expressed in a unified formula. We provide graphs and thorough analysis of the new standard type curves for both well test and rate decline analysis; the characteristics of type curves are the reflections of horizontal well production in a multiple-zone reservoir. An important contribution of our paper is that our model removed the oscillation in type curves and thus solved the negative skin problem. We also show that the characteristics of type curves depend heavily on the properties of different zones, skin factor, well length, formation thickness, etc. Our research can be applied to a real case study

    This chapter gathers three case laws, one concerning France and the two others concerning the United States. France - Decision of the Administrative Court in Strasbourg on the permanent shutdown of the Fessenheim nuclear power plant: On 9 March 2011, the administrative court in Strasbourg confirmed the government's rejection to immediately close the Fessenheim nuclear power plant, the first unit of which started operation on 1 January 1978. The court rejected the motion of the 'Association trinationale de protection nucleaire' (ATPN) filed against the decision of the Minister of Economy, Industry and Employment to refuse the final shutdown of the plant. The group, which brings together associations as well as French, German and Swiss municipalities, had taken legal action in December 2008. United States - Case law 1 - Judgment of a US Court of Appeals on public access to sensitive security information and consideration of the environmental impacts of terrorist attacks on nuclear facilities: This case concerns 1) the public's right to access classified and sensitive security information relied upon by the US Nuclear Regulatory Commission (NRC) in its environmental review; and 2) the sufficiency of the NRC's environmental review of the impacts of terrorist attacks for a proposed Independent Spent Fuel Storage Installation (ISFSI). In 2003, the NRC ruled that the National Environmental Policy Act (NEPA) did not require the NRC to consider the impacts of terrorist attacks in its environmental review for the proposed ISFSI at the Diablo Canyon Power Plant. ' NEPA mandates that all federal agencies must prepare a detailed statement on the environment impacts before undertaking a major federal action that significantly affects the human environment. In 2004, the San Luis Obispo Mothers for Peace, a group of individuals who live near the Diablo Canyon Power Plant, filed a petition in the US Court of Appeals for the Ninth Circuit challenging the NRC's 2003 decision.

  13. Conductance in double quantum well systems

    International Nuclear Information System (INIS)

    Hasbun, J E

    2003-01-01

    The object of this paper is to review the electronic conductance in double quantum well systems. These are quantum well structures in which electrons are confined in the z direction by large band gap material barrier layers, yet form a free two-dimensional Fermi gas within the sandwiched low band gap material layers in the x-y plane. Aspects related to the conductance in addition to the research progress made since the inception of such systems are included. While the review focuses on the tunnelling conductance properties of double quantum well devices, the longitudinal conductance is also discussed. Double quantum well systems are a more recent generation of structures whose precursors are the well known double-barrier resonant tunnelling systems. Thus, they have electronic signatures such as negative differential resistance, in addition to resonant tunnelling, whose behaviours depend on the wavefunction coupling between the quantum wells. As such, the barrier which separates the quantum wells can be tailored in order to provide better control of the device's electronic properties over their single well ancestors. (topical review)

    2016-06-01

    In the philosophy of well-being, there is hardly anything written on the lives of people with autism or on the question whether existing philosophical theories of well-being are suited for understanding how well the lives of autistic persons are going. This paper tries to make some progress towards filling this gap. I start by giving a concise account of autism, which highlights the huge heterogeneity among autistics. I discuss some basic features of autism, ask whether there are good reasons why we would need an account of well-being specifically for autistics and what philosophical well-being research could learn from being informed by autistic experiences and phenomenology. I then investigate to what extent the capability approach gives us a helpful theory of well-being for autistics, and what looking through an autism-lens can contribute to the further development of the capabilitarian well-being. In particular, I show that some capabilities that are crucially relevant for autistics are also relevant for the lives of non-autistic people. The final part of the paper looks at an important difficulty in using the capabilitarian account of well-being for autistics, namely: should the normative focus be on achievements (functionings) or real opportunities (capabilities)?

    1970-03-01

    A study of the possible synthesis of mordenite in geothermal wells was conducted. In 1966 as part of a series of exploratory geothermal investigations, a 500 m well was drilled which had a temperature at 250 m of 120/sup 0/C. The well has constant temperature and constant pressure and has been used to study alteration. Specimens which were placed in the well were tested for mordenite. Mordenite was synthesized when Benki clay and a 10% KOH solution were placed in a Teflon tube at 250 m (120/sup 0/C and 22.3 kg/cm/sup 2/) for three months. No mordenite was synthesized when obsidian powder was used. These results indicate the possibility of synthesis of zeolite and clay minerals in geothermal wells.

    2013-09-01

    Over the past few decades, the widespread phenomenon of Internet abuse has gained attention from the public, academia, and the media. In a departure from this negative viewpoint, however, researchers and educators have devoted considerable effort in attempting to understand the influence of online communication on people's psychological well-being. This study focuses specifically on Facebook, and proposes a research model to examine the relationships among Facebook use, online social support, general social support, and psychological well-being. Our results show that using Facebook helped college students to obtain online social support, and that online social support is an extension of general social support. However, although general social support contributes to well-being, online social support appears to have little direct effect on well-being. The relationship between online social support and well-being is mediated through the factor of general social support.

  9. Pair production by a deep potential well

    Solutions are obtained for the Dirac and Klein-Gordon equations with a one-dimensional symmetric potential well, having a flat bottom and arbitrary depth, width and field strengths at the walls. Quasi-stationary solutions describing a pair production by the well and the inverse process are obtained. It is shown that if the pair production probability is small, it is expressed in terms of the pair production probability on one wall and the particle oscillation frequency in the well. If the well has a supercritical depth, the lower continuum contains positron resonance scattering states at energies close to the real part of the quasi-stationary level energy (Zeldovich's effect). The qualitative dependence of the positron penetration coefficient through the wall on its energy and the well depth is an evidence that the solution of the so called one-particle Dirac equation describes in fact a many-particle system with a charge of 0 or 1

    International Nuclear Information System (INIS)

    John, C.J.

    1992-10-01

    Since September 1978, microseismic networks have operated continuously around US Department of Energy (DOE) geopressured-geothermal well sites to monitor any microearthquake activity in the well vicinity. Microseismic monitoring is necessary before flow testing at a well site to establish the level of local background seismicity. Once flow testing has begun, well development may affect ground elevations and/or may activate growth faults, which are characteristic of the coastal region of southern Louisiana and southeastern Texas where these geopressured-geothermal wells are located. The microseismic networks are designed to detest small-scale local earthquakes indicative of such fault activation. Even after flow testing has ceased, monitoring continues to assess any microearthquake activity delayed by the time dependence of stress migration within the earth. Current monitoring shows no microseismicity in the geopressured-geothermal prospect areas before, during, or after flow testing

At the same time, policy makers have doubled down on efforts to go beyond income when measuring well- being. We attempt to bridge these two areas by measuring the extent to which...... individuals have equal opportunities to achieve a high level of well-being. We use the German Socio-Economic Panel to measure well-being in four different ways including incomes. This makes it possible to determine if the way well-being is measured matters for identifying who the opportunity......-deprived are and for tracking inequality of opportunity over time. We find that, regardless of how well-being is measured, the same people are opportunity-deprived and equality of opportunity has improved over the past 20 years. This suggests that going beyond income has little relevance if the objective is to provide equal...

    2018-03-01

    Physician psychological wellness is an emergent outcome resulting from dynamic interactions among complex conditions. We may enhance opportunities for physician wellness by applying principles developed to improve another emergent outcome: patient safety. The Safety I approach to patient safety focuses on "what went wrong" and considers humans a liability. Safety II is a powerful complementary approach that focuses on "what went right" and values human creativity. These contrasting perspectives are described in the context of patient safety, but the underlying principles have relevance for physician psychological wellness. We can create conditions that interfere with wellness and conditions that support wellness. We can learn from exploring and reinforcing successes and improving routine processes; together, these approaches may have a greater cumulative positive impact than just addressing problems. In addition to learning from failures, there is much we can learn from success.

    Our purpose was to understand different stakeholder perceptions about the use of self-monitoring tools, specifically in the area of older adults' personal wellness. In conjunction with the advent of personal health records, tracking personal health using self-monitoring technologies shows promising patient support opportunities. While clinicians' tools for monitoring of older adults have been explored, we know little about how older adults may self-monitor their wellness and health and how their health care providers would perceive such use. We conducted three focus groups with health care providers (n=10) and four focus groups with community-dwelling older adults (n=31). Older adult participants' found the concept of self-monitoring unfamiliar and this influenced a narrowed interest in the use of wellness self-monitoring tools. On the other hand, health care provider participants showed open attitudes toward wellness monitoring tools for older adults and brainstormed about various stakeholders' use cases. The two participant groups showed diverging perceptions in terms of: perceived uses, stakeholder interests, information ownership and control, and sharing of wellness monitoring tools. Our paper provides implications and solutions for how older adults' wellness self-monitoring tools can enhance patient-health care provider interaction, patient education, and improvement in overall wellness.

  16. Analyzing the Risk of Well Plug Failure after Abandonment

    Mainguy, M.; Longuemare, P.; Audibert, A.; Lecolier, E.

    2007-01-01

    All oil and gas wells will have to be plugged and abandoned at some time. The plugging and abandonment procedure must provide an effective isolation of the well fluids all along the well to reduce environmental risks of contamination and prevent from costly remedial jobs. Previous works have analyzed the plug behavior when submitted to local pressure or thermal changes but no work has looked to the effects of external pressure, thermal and stress changes resulting from a global equilibrium restoration in a hydrocarbon reservoir once production has stopped. This work estimates those changes after abandonment on a reservoir field case using a reservoir simulator in conjunction with a geomechanical simulator. Such simulations provide the pressure and thermal changes and the maximum effective stress changes in the reservoir cap rock where critical plugs are put in place for isolating the production intervals. These changes are used as loads in a well bore stress model that explicitly models an injector well and predict stress rearrangements in the plug after abandonment. Results obtained with the well bore stress model for a conventional class G cement plug show that the main risk of failure is tensile failure because of the low tensile strength of the cement. Actually, soft sealing materials or initially pre-stressed plug appears to be more adapted to the downhole conditions changes that may occurs after well plugging and abandonment. (authors)

    Full Text Available Conventional welfare production is unsustainable. A societal emphasis on (green economic growth may therefore be superseded by an extended concept of well-being. Taking a transformative approach, science may take part in catalysing this challenging transformation of both the understanding and the level of well-being. Instead of economic growth at the expense of sustainability, we aim to cooperatively refocus on integrating economic, social and ecological perspectives into a more holistic, sustainable approach to individual and municipal well-being in Wuppertal (Germany. Therefore, the research team investigates and develops concepts of local sustainable well-being production, e.g., by employing a new indicator system and the real-world laboratory approach. What are the conditions and constraints of transforming well-being in Wuppertal and most particularly of the role of scientists in this endeavour? Answering this research question with a comparative case study approach, we have analysed our resources, processes, contexts and normativity. The results show that the role of ‘transformative scientists’ in Wuppertal faces constraints of timing and funding, as well as challenges from the different demands of science and practice. Hampered co-design interacts with role conflicts. Open-minded stakeholders are crucial for local well-being transformation, as is the awareness that urban residential districts have bottomed out. However, the normative sustainability claims of the transformative research project are not fully shared by all of its stakeholders, which is both necessary and challenging for transformative research.

While clinicians’ tools for monitoring of older adults have been explored, we know little about how older adults may self-monitor their wellness and health and how their health care providers would perceive such use. Methods We conducted three focus groups with health care providers (n=10) and four focus groups with community-dwelling older adults (n=31). Results Older adult participants’ found the concept of self-monitoring unfamiliar and this influenced a narrowed interest in the use of wellness self-monitoring tools. On the other hand, health care provider participants showed open attitudes towards wellness monitoring tools for older adults and brainstormed about various stakeholders’ use cases. The two participant groups showed diverging perceptions in terms of: perceived uses, stakeholder interests, information ownership and control, and sharing of wellness monitoring tools. Conclusions Our paper provides implications and solutions for how older adults’ wellness self-monitoring tools can enhance patient-health care provider interaction, patient education, and improvement in overall wellness.

    Health care in the United States is changing rapidly under pressure from both political and professional stakeholders, and one area on the front line of required change is the discipline of case management. Historically, case management has worked to defragment the health care delivery system for clients and increase access to health care. Case management will have an expanded role resulting from Affordable Care Act initiatives to improve health care. This article includes definitions of case management, current issues related to case management, case management standards of practice, and a case study of the management of pediatric chronic disease.

    In developed countries, economic and financial well-being is playing a crucial positive role in ageing and inclusion processes. Due to the complexity and pervasiveness of financial economy in the real life, more and more social as well as individual well-being are perceived as influenced by financial conditions. On the other hand, the demographic circumstances drive scholars as well as politicians to reflect on ageing dynamics. Bridging the two domains, the following research focuses on the role of the financial well-being as a mediating role of general well-being in elder people. The assumption is that elderly people have specific financial needs that sometimes are not covered by financial providers' offers. The motivation is mainly on the role of information asymmetries between elder consumers and financial institutions. On the dynamics of these asymmetries, the research will specifically investigate the role of financial literacy, as the ability of comprehension of elder people of their needs and of financial information. The applicative implication of this research work consists in finding the determinants of financial well-being for elders and the definition of their specific financial competencies, in order to 1) identify educational and regulatory guidelines for policy makers in charge of creating financial market transparency conditions, and to 2) support design of organizational mechanisms as well as financial product/services for this specific target of client. The following chapter presents preliminary explorative results of a survey delivered on 200 elder individuals (65-80 yrs.) leaving in Milan. Findings show that active elders consider the ability of managing personal wealth as one of the core determinant of well-being, although the economic and financial literacy is limited. Furthermore, the chapter proposes a research agenda for scholars interested in exploring the relationship between financial well-being and ageing.

    Previous work by McGrail et al. (2013, 2015) has evaluated the possibility of pairing compressed air energy storage with geothermal resources in lieu of a fossil-fired power generation component, and suggests that such applications may be cost competitive where geology is favorable to siting both the geothermal and CAES components of such a system. Those studies also note that the collocation of subsurface resources that meet both sets of requirements are difficult to find in areas that also offer infrastructure and near- to mid-term market demand for energy storage. This study examines a novel application for the compressed air storage portion of the project by evaluating the potential to store compressed air in disused wells by amending well casings to serve as subsurface pressure vessels. Because the wells themselves would function in lieu of a geologic storage reservoir for the CAES element of the project, siting could focus on locations with suitable geothermal resources, as long as there was also existing wellfield infrastructure that could be repurposed for air storage. Existing wellfields abound in the United States, and with current low energy prices, many recently productive fields are now shut in. Should energy prices remain stagnant, these idle fields will be prime candidates for decommissioning unless they can be transitioned to other uses, such as redevelopment for energy storage. In addition to the nation’s ubiquitous oil and gas fields, geothermal fields, because of their phased production lifetimes, also may offer many abandoned wellbores that could be used for other purposes, often near currently productive geothermal resources. These existing fields offer an opportunity to decrease exploration and development uncertainty by leveraging data developed during prior field characterization, drilling, and production. They may also offer lower-cost deployment options for hybrid geothermal systems via redevelopment of existing well-field infrastructure

  3. Well-being, capabilities and philosophical practice

    Full Text Available The concept of well being has become the main criterion to assess quality of life in contemporary society. Individual well-being describes the individual quality of life, while social well-being refers to quality of life in a society. Given that well-being has a multitude of dimensions, a unique definition of it is elusive to scholars. In this article social well-being is conceptualised as a dynamic process within the context set by social integration as one’s relationship to society and the community. This includes the quality of interaction between the individual and society and one’s ‘social actualisation’ understood as the realisation of one’s social capacities. Social actualisation also involves one’s ability to influence social processes and to benefit from social cohesion, which consists, in any society, of the quality, organisation and functioning of the social world. Hence the ability to impact society is an integral part of individual well being. This paper suggests that philosophical practice as a new paradigm in the humanities holds out promise for the improvement of both individual and social well-being.

    We obtain solutions of the Dirac and Klein-Gordon equations for a symmetric one-dimensional potential well with a flat bottom, and arbitrary depth, width, and field strength at the walls. Quasistationary solutions are found describing pair creation by the well, and the inverse process. It is shown that when the probability of pair creation by the well is small, it can be expressed in terms of the probability of pair creation at one of the walls and the oscillation frequency of the particle in the well. Among the states of the lower continuum, there are positron resonance scattering states for supercritical well depths. The energies of these states are close to the real part of the quasistationary energy level (the Zel'dovich effect). The qualitative dependence of the transmission coefficient of the positron through the well on its energy and the well width supports the idea that the solution of the so-called one-particle Dirac equation describes a many-particle system with charge 0 or 1

    People receiving publicly funded behavioral health services for severe mental disorders have shorter lifespans and significantly impaired health-related quality of life compared to the general population. The aim of this article was to explore how peer wellness coaching (PWC), a manualized approach to pursue specific physical wellness goals, impacted goal attainment and overall health related quality of life. Deidentified archival program evaluation data were examined to explore whether peer delivered wellness coaching had an impact on 33 service recipients with regard to goal attainment and health-related quality of life. Participants were served by 1 of 12 wellness coach trainees from a transformation transfer initiative grant who had been trained in the manualized approach. Coaching participants and their coaches reported significant progress toward the attainment of individually chosen goals, 2 to 4 weeks after establishing their goals. After 8 to 10 weeks of peer delivered wellness coaching, improvements were evident in the self-report of physical health, general health, and perceived health. These improvements were sustained 90 days later. PWC is potentially a promising practice for helping people choose and pursue individual goals and facilitating positive health and wellness changes. Rigorous controlled research with larger samples is needed to evaluate the benefits of peer delivered wellness coaching. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

  6. Kuwaiti oil wells blowout - aspects and effects

    When the Iraqi troops were forced to leave Kuwait, they left behind them the greatest oil catastrophe human beings have ever experienced. Fire plumes of tons of gases of principal pollutants, hydrocarbons, soot and associated metals were ejected up to a height of about 5 km. The retreating forces blew off about 1200 wells all over Kuwait fields. Of these 1200 wells, 614 are on fire. Four firefighting companies were hired to start work immediately after the liberation of Kuwaiti to control these wells. Three of these companies were from the U.S.A. and one from Canada. The number of these companies steadily increased along with logistical support. There are now 28 teams made up of private and multinational companies. This paper will concentrate on two main aspects. The first part will focus on the up-to-date engineering aspects of bringing the blown-out wells under control, focusing on oil well fires and the difficulties encountered, such as equipment availability, ordnance clearance and logistical support. The paper then describes the procedures used to control the wells, and the steps taken to reach this aim are presented. Finally the number of wells controlled, area-wise in different fields, with their original status, is also introduced. The second part will concentrate on the environmental aspects, covering the impact of the plumes on air quality, air pollution and health. The paper then discusses the effect on marine environment, vegetation and the soil. Finally, a forecast, conclusions and recommendations are presented. (author)

  7. Well test analysis in fractured media

    1987-04-01

    The behavior of fracture systems under well test conditions and methods for analyzing well test data from fractured media are investigated. Several analytical models are developed to be used for analyzing well test data from fractured media. Numerical tools that may be used to simulate fluid flow in fractured media are also presented. Three types of composite models for constant flux tests are investigated. These models are based on the assumption that a fracture system under well test conditions may be represented by two concentric regions, one representing a small number of fractures that dominates flow near the well, and the other representing average conditions farther away from the well. Type curves are presented that can be used to find the flow parameters of these two regions and the extent of the inner concentric region. Several slug test models with different geometric conditions that may be present in fractured media are also investigated. A finite element model that can simulate transient fluid flow in fracture networks is used to study the behavior of various two-dimensional fracture systems under well test conditions. A mesh generator that can be used to model mass and heat flow in a fractured-porous media is presented.

    The lexicographic order is not representable by a real-valued function, contrary to many other orders or preorders. So, standard tools and results for well-posed minimum problems cannot be used. We prove that under suitable hypotheses it is however possible to guarantee the well-posedness of a lexicographic minimum over a compact or convex set. This result allows us to prove that some game theoretical solution concepts, based on lexicographic order are well-posed: in particular, this is true for the nucleolus.
