    1995-01-01

    To construct a digital simulation of a plume of brackish water in the surficial Biscayne aquifer of central Dade County, Florida, that originated from a flowing artesian well, it was necessary to quantify the rate of spillage and the consequent point-source loading of the aquifer. However, a flow-rate measurement (2,350 gallons per minute) made 2 months after drilling of the well in 1944 was inconsistent with later measurements (1,170 gallons per minute) in 1964, 1965, and 1969. Possible explanations were the: (1) drawdown of the aquifer over time; (2) raising of the altitude at which the water was discharged; (3) installation of 80 feet of 8-inch liner; (4) an increase in the density of the flowing water; and (5) gradual deterioration of the well casing. The first approach to reconciling the measured flow rates was to apply a form of the equation for constant-drawdown analysis often used to estimate aquifer transmissivity. Next, a numerical simulation analysis was made that pro- vided the means to account for friction loss in the well and recharge across vertically adjacent con- fining layers and from lateral boundaries. The numerical analysis required the construction of a generalized model of the subsurface from the surficial Biscayne aquifer to the cavernous, dolomitic Boulder Zone at a depth of 3,000 feet. Calibration of the generalized flow model required that the moddle confining unit of the Floridan aquifer system separating the artesian flow zone in the Upper Floridan aquifer from the Lower Floridan aquifer (the Boulder Zone) have a vertical hydraulic conductivity of at least 1 foot per day. The intermediate confining unit separating the flow zone from the surficial Biscayne aquifer was assigned a much lower hydraulic conductivity (0.01 foot per day or less). The model indicated that the observed mounding of Upper Floridan aquifer heads along the axis of the Florida Peninsula was related to the variable depth of the freshwater and brackish-water zone

Los tratamientos de riego tuvieron un efecto positivo sobre la producción de biomasa aérea obteniéndose un 24% más de producción de biomasa que en la situación de secano (precipitaciones. Entre los tratamientos con riego también se manifestaron diferencias estadísticamente significativas. La alfalfa regada con aguas residuales urbana supero en un 19% a la cultivada con agua de perforación. La eficiencia del uso del agua por parte del cultivo se incrementó cuando el riego se realizó con aguas residuales urbanas. Además, se determinó que la alfalfa regada con agua residual, supera los valores nutritivos del cultivo que crece en condiciones sin riego; encontrándose 39% más de proteínas, 14% más de digestibilidad e igual porcentaje de energía metabólica. Se puede concluir que el agua residual urbana representa otra posible fuente de agua, factible de ingresar al suelo y estar a disposición para el cultivo de alfalfa.The objective of this study was to analyse the production of alfalfa biomass, the efficiency of water use and the nutritional value of forage, inside an irrigation structure of an experimental facility that uses treated urban wastewater, artesian well water and rainfall, at the campus of the Universidad National de Rio Cuarto (Córdoba-Argentina. The irrigation treatment had a positive effect on the production of biomass of alfalfa. On an average 24% increase in production was observed when compared to dry-land farming. Regarding the quality of the irrigation water, statistical differences in production were observed, the irrigation with urban wastewater produced 19% more than that of well water. The

    Full Text Available The artesian aquifers provide economical and sustainable source of groundwater for irrigation and domestic use. GIS (Geographic Information System was used for development and integration of spatial databases, analysis and visualization of spatial data in two- and three-dimensional views. The aquifer system of Daraban Rod-Kohi area of DI Khan was analyzed to identify potential artesian aquifers using geological sections of the observation wells representing detail of subsurface lithology and strata encountered. According to an estimate, about 1,700 million m3 of extractable volume of groundwater exists in this part of rod-kohi area. Different profile sections were drawn to analyze the subsurface condition of the study area using Rockworks GIS-based software. The geo-processing technique of horizontal litho-blending was utilized for lithological modeling. Based on stratigraphic information of the area, three distinct aquifers were identified down to a depth of about 200 meters among which two are semi-confined to confined having prospects of artesian water. The 2D and 3D analysis show that characteristics of the confined aquifers vary spatially with the subsurface lithology and structural setup of the area. The depth range of confined layer-1 is found between 118 and 133 meters while of confined layer-2 between 182 and 195 meters. The output data indicated a close agreement with the observed data of the artesian wells. The study results can provide base for detail investigation of artesian resource and selection of potential sites for installation of artesian wells in the target area.

    Baltic artesian basin (BAB) is a multi-layer sedimentary basin spanning around 480'000 km2. BAB is located in the territory of Latvia, Lithuania and Estonia, parts of Poland, Russia, Belarus and large area of the Baltic Sea, including island of Gotland. The thickness of sedimentary cover is about 5000 m in the south-western part. Crystalline bedding reaches the surface in the northern and north-western parts. The aim of the present work is development of the model of geometric structure and three dimensional finite element mesh for the hydrogeological model of the whole BAB. The information that is used to build the geometrical structure includes: (1) Stratigraphic information from boreholes in Latvia and Estonia (2) Maps of height isolines of geological layers for Latvia and Lithuania (3) Maps of sub-quaternary deposits in Latvia and Lithuania (4) Maps of fault lines on the crystalline basement surface in Latvia, Lithuania and Estonia (5) Buried valley data from Latvia and Estonia (6) Earth topography data (7) Baltic sea depth data (8) Data from published geological cross-sections, information from books and other sources. Unification of the heterogeneous information from different sources, which are employed for building of the geometrical structure of the model are performed. Special algorithms are developed for this purpose considering the priority, importance and plausibility of each of the data sources. Pre-processing of the borehole information to screen out the outlying borehole data has been performed. Model of geological structure contains 42 layers. It includes aquifers and aquitards from Cambrian up to the Quaternary deposits. Fault displacements are incorporated into the model taking into account data from the published structural maps. Four reconstructed regional erosion surfaces (upper Ordovician, Devonian, Permian and Quaternary) are included into the model Three dimensional mesh of the geological structure is constructed layer-wise.

    The isotope hydrology of the Great Artesian Basin has been systematically investigated. Because of the size of the Basin and the long residence times of the groundwater, carbon-14 techniques can be used only to delineate recharge areas. Isochrones over the whole basin have been developed with chlorine-36 and compared with the calculated ages. The results of surveys of dissolved hydrocarbons and uranium series nuclides are reported

    Analysis of groundwater chemistry can yield important insights about subsurface conditions, and provide an alternative and complementary method for characterizing basin hydrogeology, especially in areas where hydraulic data are limited. More specifically, hydrochemical facies have been used for decades to help understand basin flow and transport, and a set of facies were developed for the Roswell Artesian Basin (RAB) in a semi-arid part of New Mexico, USA. The RAB is an important agricultural water source, and is an excellent example of a rechargeable artesian system. However, substantial uncertainties about the RAB hydrogeology and groundwater chemistry exist. The RAB was a great opportunity to explore hydrochemcial facies definition. A set of facies, derived from fingerprint diagrams (graphical approach), existed as a basis for testing and for comparison to principal components, factor analysis, and cluster analyses (statistical approaches). Geochemical data from over 300 RAB wells in the central basin were examined. The statistical testing of fingerprint-diagram-based facies was useful in terms of quantitatively evaluating differences between facies, and for understanding potential controls on basin groundwater chemistry. This study suggests the presence of three hydrochemical facies in the shallower part of the RAB (mostly unconfined conditions) and three in the deeper artesian system of the RAB. These facies reflect significant spatial differences in chemistry in the basin that are associated with specific stratigraphic intervals as well as structural features. Substantial chemical variability across faults and within fault blocks was also observed.

  9. Geochemical evolution of groundwaters from the Great Artesian Basin

    International Nuclear Information System (INIS)

    Chemical and isotopic mass balances of major elemental species throughout the Great Artesian Basin were studied along with an equilibrium mineral-water model. With progressive distance down the flow path, Na and K are removed, relative to CI, by reconstitution reactions involving kaolinite and Na-montorillonite and illite, respectively. Ca and Mg behave conservatively in general throughout the interior of the basin. Mass balance calculations suggest that increasing 13C differentials along flow paths result from carbon dioxide production from methanogenesis rather than dissolution of calcium carbonate. While bicarbonate is the major anion, rather than chloride as in other basins, there appears to be similar mineralwater reactions occurring in each of the basins, but subtle differences within the recharge zone result in the evolution of a bicarbonate dominated system

  10. Aspects of the isotope hydrology of the Great Artesian Basin, Australia

    International Nuclear Information System (INIS)

    A study has been made of the isotope hydrology of the principal Jurassic aquifer of the Queensland portion of the Great Artesian Basin down-gradient of the recharge area. Much of the data have been interpreted in terms of the residence times of the groundwater samples which were up to 350,000 years. It is postulated that the observed systematic variations in the chloride levels reflect variations in the rate of infiltration of recycled salt throughout the late Quaternary. The minimum and maximum in the chloride curve correlate with the last glacial and interglacial period respectively. The bicarbonate ion levels are perturbed by the dissolution of carbonate minerals. About 0.1% of the aquifer material would have been dissolved since the mid-Tertiary when the present hydrodynamic conditions were established if dissolution rates calculated from the geochemical model are representative. The D/H ratios were found to be extremely constant. The 46 wells sited away from the recharge area have a mean deltaD of -41.8 per mille and a standard deviation of 1.1. There was no isotopic evidence for exchange of oxygen between water and the host rock despite the long contact periods, sometimes at elevated temperatures. A 226Ra, 238U survey showed that radium is frequently in excess despite extensive leaching since the Tertiary times and the fact that the time scales associated with the transport of water are large compared with the half life of 226Ra.

    Subsurface hydrology of the Baltic Artesian basin has changed rapidly during the Quaternary period. Glacial and several interglacial phases as well as the change in the sea level led to complicated subsurface hydrology and a large difference in groundwater chemical as much as isotopic content. Baltic artesian basin fully covers territory of Latvia, Lithuania and Estonia; also parts of Poland, Russia, and Belarus are included. This work aims to give better overview of the complexity of the groundwater recharge and discharge dynamics beyond country borders, taking into account only shared geological framework, common climate conditions and development during the Quaternary period. To maintain better understanding of the processes that took part in the formation of groundwater that can be observed nowadays several methods were applied placing major emphasis on the new oxygen and hydrogen stable isotope ratio results. Additionally large scale modeling as well as hydrochemistry and trace element concentrations was used. Paleowaters usually are isotopically lighter, that facilitate to detect their presence. Earlier investigations in the northern part of the basin indicated glacial melt water intrusion in the Cambrian-Vendian aquifer corrected radiocarbon age suggests that this meltwater intrusion took place during the late Weichelian. Several radiocarbon and stable isotope studies in groundwater have been done at the southern part of the basin as well reporting extensive groundwater recharge during the Late Pleistocene in the Devonian aquifers; authors suggest that recharge took place under different recharge mechanisms compared with the northern part. So far no similar studies were accomplished in the central part of the basin, thus to make clearer picture and possibility to find the mixing line between groundwater bodies of different origin, the new groundwater samples were collected from more than 200 wells mainly in the territory of Latvia.

    In the Roswell Basin in southeastern New Mexico artesian water is produced from cavernous zones in the carbonate rocks of the San Andres formation and the lower part of the Chalk Bluff formation, both of Permian age. The Hondo Reservoir, 9 miles west-southwest of Roswell, was completed by the U. S. Bureau of Reclamation in 1907, to store waters of the Rio Hondo for irrigation. The project was not successful, as the impounded water escaped rapidly through holes in the gypsum and limestone of the San Andres formation constituting its floor. Of 27,000 acre~feet that entered the reservoir between 1908 and 1913, only 1,100 acre-feet was drawn Ollt for use, the remainder escaping through the floor of the reservoir. Since 1939, plans have been drawn up by the State Engineer and by Federal agencies to utilize the reservoir to protect Roswell from floods. It has also been suggested that water from the Pecos River might be diverted into underground storage through the reservoir. Sinkholes in the Roswell Basin are largely clustered in areas where gypsum occurs in the bedrock. Collapse of strata is due to solution of underlying rock commonly containing gypsum. Domes occur in gypsiferous strata near Salt Creek. The Bottomless Lakes, sinkhole lakes in the escarpment on the east side of the Pecos, are believed to have developed in north-south hinge-line fractures opened when the westernmost beds in the escarpment collapsed. Collapse was due to solution and removal of gypsiferous rock by artesian water which now fills the lakes.

    While of great national and societal significance, and importance in its own right, the Great Artesian Basin of Australia is an iconic example of a continental scale artesian groundwater system. New geochemical, hydrological, and neo-tectonic data suggests that existing models that involve recharge in eastern Australia, relatively simple flow paths and discharge in springs in the western margin require modification. New geochemical data indicate a small volume flux of deeply derived (endogenic) fluids mixing into the aquifer system at a continental scale. Neotectonic data indicates active tectonism today that provides a fluid pathway through faults for the deeply sourced endogenic fluids to discharge in GAB travertine depositing springs. (authors)

    Cambrian-Vendian Aquifer System (CVAS) is the deepest confined aquifer system used for water consumption in northern part of Baltic Artesian Basin (BAB). A regional groundwater flow and transport model (Visual Modflow) was used to investigate the paleohydrogeological scientific and contemporary management problems of CVAS. The model covers the territory of Estonia and its close surrounding, all together 88,000 km2 and includes all main aquifers and aquitards from ground surface to as low as the impermeable part of the crystalline basement. Three-dimensional distribution of groundwater heads, flow directions, velocities, and rates as well as transport and budget characteristics were simulated by the model. Water composition was changed significantly during the last glaciations.Strongly depleted O and H stable isotope composition, absence of 3H and low radiocarbon concentration are the main indicators of glacial origin of groundwater in the Cambrian-Vendian aquifer in northern Estonia. The noble gas analyses allowed concluding, that palaeorecharge took place at temperatures around the freezing point. While in North Estonia, most of water was changed by glacial melt water, high salinity water is till preserved in Southern part of Estonia.First results of modeling suggest that during the intrusion period lasting 7.3-9.3 ka the front of glacial thaw water movement had southeast direction and reachedto 180-220 kmfrom CVAS outcrop in Baltic Sea. Confining layer of CVAS is cut through by deep buried valleys in several places in North Estonia making possible for modern precipitation to infiltrate into aquifer system in present day. In case of natural conditions, the water pressure of CVAS is few meters above sea level and most of valleys act as discharge areas for aquifers system. Two regional depression ones have formed in North Estonia as a result of groundwater use from CVAS. Water consumption changes the natural groundwater gradient, flow direction and thereforerecharge

    Full Text Available Conceptual and respective quantitative models of speleogenesis/karstifi cation developed for unconfi ned aquifers do not adequately representspeleogenesis in confi ned settings. A conceptual model for speleogenesis in confi ned settings is suggested, based on views about hydrauliccontinuity in artesian basins and close cross-formation communication between aquifers in multi-storey artesian systems. Soluble unitssandwiched between insoluble porous/fi ssured formations (common aquifers initially serve as low permeability beds separating aquifersin a confi ned system. Conduits evolve as result of vertical hydraulic communication between aquifers across the soluble bed ("transversespeleogenesis". Recharge from the adjacent aquifer is dispersed and uniform, and fl ow paths across the soluble bed are rather short. There is a specific hydrogeologic mechanism inherent in artesian transverse speleogenesis (restricted input/output that suppresses the positive flow-dissolution feedback and hence speleogenetic competition in fissure networks, and accounts for the development of more pervasive channelling in confi ned settings, of maze patterns where appropriate structural prerequisites exist. This is the fundamental cause for the distinctions between cave morphologies evolving in unconfi ned and confi ned aquifers and for eventual distinctions of karstic permeability, storage characteristics and flow system behaviour between the two types of aquifers.Passage network density (the ratio of the cave length to the area of the cave fi eld, km/km2 and cave porosity (a fraction of the volume of a cave block, occupied by mapped cavities are roughly one order of magnitude greater in confi ned settings than in unconfined. Average areal coverage (a fraction of the area of the cave field occupied by passages in a plan view is about 5 times greater in confi ned settings. Conduit permeability in unconfi ned settings tends to be highly heterogeneous, whereas it is more

    International Nuclear Information System (INIS)

    The Great Artesian Basin extends across 1.7 × 106 km2 or one fifth of the Australian continent. Annual rainfall ranges from 100 mm in the arid western parts to a maximum of 600 mm near the main recharge areas along the eastern basin margin. Average annual runoff is less than 10 mm and generally less than 5 mm. Ephemeral rivers dominate the land surface of the basin, except for a few perennial rivers in the most northern, tropical parts of the region. Most interior rivers drain into Lake Eyre (a dry salt pan at 12 m below sea level); however, the river waters often evaporate or infiltrate before reaching Lake Eyre because of the long distances. With little or no surface water present in the dry, hot and harsh climate of Australia’s interior, the ability of the early settlers to explore and exploit the resources of this region were limited.

  19. Catastrophic floods may pave the way for increased genetic diversity in endemic artesian spring snail populations.

    Jessica Worthington Wilmer

    Full Text Available The role of disturbance in the promotion of biological heterogeneity is widely recognised and occurs at a variety of ecological and evolutionary scales. However, within species, the impact of disturbances that decimate populations are neither predicted nor known to result in conditions that promote genetic diversity. Directly examining the population genetic consequences of catastrophic disturbances however, is rarely possible, as it requires both longitudinal genetic data sets and serendipitous timing. Our long-term study of the endemic aquatic invertebrates of the artesian spring ecosystem of arid central Australia has presented such an opportunity. Here we show a catastrophic flood event, which caused a near total population crash in an aquatic snail species (Fonscochlea accepta endemic to this ecosystem, may have led to enhanced levels of within species genetic diversity. Analyses of individuals sampled and genotyped from the same springs sampled both pre (1988-1990 and post (1995, 2002-2006 a devastating flood event in 1992, revealed significantly higher allelic richness, reduced temporal population structuring and greater effective population sizes in nearly all post flood populations. Our results suggest that the response of individual species to disturbance and severe population bottlenecks is likely to be highly idiosyncratic and may depend on both their ecology (whether they are resilient or resistant to disturbance and the stability of the environmental conditions (i.e. frequency and intensity of disturbances in which they have evolved.

To maintain better understanding of the processes that took part in the formation of groundwater that can be observed nowadays several methods were applied placing major emphasis on the new oxygen and hydrogen stable isotope ratio results. Earlier investigations in the northern part of the basin indicated glacial melt water intrusion in the Cambrian-Vendian. Several radiocarbon and stable isotope studies in groundwater have been done at the southern part of the basin as well reporting extensive groundwater recharge during the Late Pleistocene suggesting that recharge took place under different recharge mechanisms compared with the northern part. In 2010 to 2012 an extensive field campaign was undertaken, collecting more than 300 groundwater samples for deuterium and stable oxygen, 30 for stable carbon and 10 for radiocarbon analysis mostly from central part (Latvia) of the BAB covering all the major aquifer systems where previously collected data was sparse or absent. A specific motivation for the research was to identify relict glacial meltwater in the groundwater system. The broader aim was to estimate the baseline isotopic composition of groundwater in the region. Here a new data set is presented. Na-Ca-Cl brine found at the deepest - stagnation zone and is characterized by δ18O values above -5 o and δD values approaching -40 o in respect to VSMOW.

    A strictly anaerobic, thermophilic bacterium, designated strain Y170(T), was isolated from a microbial mat colonizing thermal waters of a run-off channel created by the free-flowing waters of a Great Artesian Basin (GAB) bore well (New Lorne bore; registered number 17263). Cells of strain Y170(T) were slightly curved rods (1.2-12x0.8-1.1 mum) and stained Gram-negative. The strain grew optimally in tryptone-yeast extract-glucose medium at 70 degrees C (temperature range for growth was 55-80 degrees C) and pH 7 (pH range for growth was 5-9). Strain Y170(T) grew poorly on yeast extract as a sole carbon source, but not on tryptone (0.2 %). Yeast extract could not be replaced by tryptone and was obligately required for growth on tryptone, peptone, glucose, fructose, galactose, cellobiose, mannose, sucrose, xylose, mannitol, formate, pyruvate, Casamino acids and threonine. No growth was observed on arabinose, lactose, maltose, raffinose, chitin, xylan, pectin, starch, acetate, benzoate, lactate, propionate, succinate, myo-inositol, ethanol, glycerol, amyl media, aspartate, leucine, glutamate, alanine, arginine, serine and glycine. End products detected from glucose fermentation were acetate, ethanol and presumably CO(2) and H(2). Iron(III), manganese(IV), thiosulfate and elemental sulfur, but not sulfate, sulfite, nitrate or nitrite, were used as electron acceptors in the presence of 0.2 % yeast extract. Iron(III) in the form of amorphous Fe(III) oxhydroxide and Fe(III) citrate was also reduced in the presence of tryptone, peptone and Casamino acids, but not with chitin, xylan, pectin, formate, starch, pyruvate, acetate, benzoate, threonine, lactate, propionate, succinate, inositol, ethanol, glycerol, mannitol, aspartate, leucine, glutamate, alanine, arginine, serine or glycine. Strain Y170(T) was not able to utilize molecular hydrogen and/or carbon dioxide in the presence or absence of iron(III). Chloramphenicol, streptomycin, tetracycline, penicillin and ampicillin and

    Major Paleozoic artesian aquifers in the southeastern Bighorn Basin of Wyoming area, in descending order, the Tensleep Sandstone; the Madison Limestone and Bighorn Dolomite, which together form the Madison-Bighorn aquifer; and the Flathead Sandstone. Operating yields commonly are more than 1,000 gallons per minute from flowing wells completed in the Madison-Bighorn aquifer. The initial test of one well indicated a flow of 14,000 gallons per minute. Wellhead pressures range from less than 50 to more than 400 pounds per square inch. Transmissivities are 500-1,900 feet squared per day for the Madison-Bighorn aquifer and 90-325 feet squared per day for the Tensleep and Flathead Sandstones. Despite extensive development for irrigation there have been few decreases in pressure. Some decreases in pressure have occurred in wells completed in the Flathead Sandstone. Fractures along linear structural features result in significant secondary permeability and allow upward interformational movement of water that affects the altitude of the potentiometric surfaces in the Tensleep Sandstone and Madison-Bighorn aquifer. Upward-moving water from the Tensleep and other formations discharges at the land surface as springs along or near these lineations. Water from the aquifers generally contains minimal concentrations of dissolved solids and individual constituents but has excessive hardness. The water is satisfactory for irrigation and other purposes when hardness is not a detrimental factor. Wellhead temperatures range from 11 degrees to 27.5 degrees C, giving a geothermal gradient of about 0.44 degrees C per 100 feet. (USGS)

  4. Distribution of natural radionuclides of uranium and thorium series in the process of artesian water treatment for drinking consumption

    International Nuclear Information System (INIS)

    Distribution of natural radionuclides of uranium and thorium series during the treatment of artesian water for drinking consumption is studied using vacuum-emanation and gamma spectrometry methods. During the water treatment hydroxide precipitates are produced at the station, which are isolated using a sand filter, radium isotopes being coprecipitated alongside with them. As a result of this radioactive waste is accumulated at the station, radium isotope concentration in it being equivalent to radium isotope concentration in uranium-thorium ores with 0:11% uranium and 0.56% thorium content. radium isotope concentration in water, delivered to the user do not exceed the established domestic normatives do not exceed the established domestic normatives

    Non-native suckermouth armored catfishes (Loricariidae) of the genus Pterygoplichthys are now common throughout much of peninsular Florida. In this paper, we present preliminary observations on interactions between a Pterygoplichthys species, tentatively identified as P. disjunctivus (Weber, 1991), and endangered native Florida manatees, Trichechus manatus latirostris (Harlan, 1824), in artesian spring systems in Florida's St. Johns River drainage. The introduced catfish have become abundant in spring habitats, sites used by manatees as winter thermal refuges. In the spring runs, Pterygoplichthys regularly attaches to manatees and grazes the epibiota on their skin. On occasion, dozens of Pterygoplichthys congregate on individual manatees. Manatee responses varied widely; some did not react visibly to attached catfish whereas others appeared agitated and attempted to dislodge the fish. The costs and/or benefits of this interaction to manatees remain unclear.

    A dye-tracing test is employed to study the karst development and flow regime at an artesian limestone sub-aquifer, the Khersan3 Dam site, Zagros Zone, Iran. Tracer breakthrough curves showed an early dominant peak followed by a pronounced tailing effect. The peak concentration was a response to induced pressure during dye injection. The results suggest that the dye was pushed into the small pores and fissures around the injection point during dye injection. Hence, the dye moved out as a result of matrix and fissure diffusive processes and created a long pronounced tailing. The maximum flow velocity in the upper artesian sub-aquifer ranged from 0.97 to 2.9 m/h. However, the mean tracer velocity ranged from 0.19 to 0.51 m/h based on the mean residence tracer time; consequently, the flow regime in the artesian sub-aquifer was determined to be mainly diffusive. The results reveal (1) a low hydraulic gradient from upstream of the dam axis to downstream; consequently, there is no considerable flow; (2) poor karst development and diffuse flow at the tracing test area; (3) a discharge zone at a location downstream of the dam axis which is the main terminal of general flow direction at the dam site.

    The Sacramento Mountains and the adjacent Roswell Artesian Basin, in south-central New Mexico (USA), comprise a regional hydrologic system, wherein recharge in the mountains ultimately supplies water to the confined basin aquifer. Geologic, hydrologic, geochemical, and climatologic data were used to delineate the area of recharge in the southern Sacramento Mountains. The water-table fluctuation and chloride mass-balance methods were used to quantify recharge over a range of spatial and temporal scales. Extrapolation of the quantitative recharge estimates to the entire Sacramento Mountains region allowed comparison with previous recharge estimates for the northern Sacramento Mountains and the Roswell Artesian Basin. Recharge in the Sacramento Mountains is estimated to range from 159.86 × 106 to 209.42 × 106 m3/year. Both the location of recharge and range in estimates is consistent with previous work that suggests that ~75 % of the recharge to the confined aquifer in the Roswell Artesian Basin has moved downgradient through the Yeso Formation from distal recharge areas in the Sacramento Mountains. A smaller recharge component is derived from infiltration of streamflow beneath the major drainages that cross the Pecos Slope, but in the southern Sacramento Mountains much of this water is ultimately derived from spring discharge. Direct recharge across the Pecos Slope between the mountains and the confined basin aquifer is much smaller than either of the other two components.

    Understanding the water balance of large groundwater systems is fundamental for the sustainable management of the resource. The vertical leakage (i.e. discharge to upper aquifers or the unconfined water table) component of the Great Artesian Basin (GAB) is an example of a poorly constrained but large component of the water balance of Australia's largest groundwater resource. Field estimates of phreatic evapotranspiration (ET) were made at discharge zones along the southwestern margin of the GAB using eddy covariance station and micro-lysimeter measurements, and inversion of chloride/isotope soil profile measurements. The field estimates were assigned to three major landforms associated with areas of increasingly higher evaporative discharge and progressively decreasing depths to the water table. These landforms were mapped using remote sensing and digital elevation data, with characteristically higher soil moisture, salt precipitation, and lower surface temperature compared to areas distal to discharge zones. Based on the field measurements, broad ranges of phreatic ET (0.5-10, 10-100 and 100-300 mm y-1) were assigned to the major land-types. The higher phreatic ET discharge zones mapped by supervised classification of satellite data are 8-28% of the total regional vertical leakage component estimated by numerical modelling of the GAB. In comparison, the higher discharge zones estimated by landform mapping are 73-251% of the total vertical leakage component estimated by modelling. The mapped distribution of the high discharge areas has important implications for modelling of the GAB. In the western sub-basin, most of the estimated recharge can be accounted for by phreatic ET in the high discharge zones located around the Basin margins, implying that vertical leakage rates distal to the margins are very low and that discharge may exceed current recharge. In contrast, the results for the eastern sub-basin suggest that vertical leakage rates around the South

    The dominant paradigm for the Great Artesian Basin over the last several decades has documented recharge in the eastern Australian Great Dividing Ranges, relatively simple regional SW flow paths in a confined aquifer system (J-K aquifer), and discharge in springs and bores in the western GAB. New geochemical and hydrologic data suggest this model needs modifications in several fundamental ways. 1) 3He/4He synthesis of springs and bores from the GAB show persistent but variable inputs of deeply derived fluid that contain mantle 3He. 3He/4He values up to 3.4 RA are present in the eastern GAB , comparable to RA of 3-4 in the southeastern GAB, and RA of 3 from volcanic regions outside the GAB, e.g. Caroline Well of Mt Gambier volcanic district. These high values (relative to MORB RA= 8) suggest that up to 40% of the He in some GAB groundwaters is from the mantle and that fluid/gas composition is influenced by basalt transfer in the lower lithosphere, microseismicity in the upper crust, and ascent of fluids up faults into the aquifer. 3He/4He data from mound springs in the western GAB have RA up to 0.09 and CO2/3He= 4x109 (Bubble Mound Springs). Given the high 4He contributions from radiogenic crust in the region and the old age of these waters, these values also suggest input of mantle fluids that have traveled up deep-seated faults into the J-K aquifer. 2) Water chemistry and C-isotope values also suggest mixing of endogenic (deeply derived) fluids with aquifer waters such that water quality in the J-K aquifer is a product of water evolution along far-traveled flow paths from the Great Dividing ranges plus local inputs of fluids from below into the aquifer. C-isotope data show that a significant percentage of the CO2 is also likely from mantle sources. 3) Hydrochemical data indicate that spring groups in the western GAB that were considered the dominant discharge springs (Dalhousie and South Australian mound springs) are hydrochemically distinct from each other and

  11. 81Br, 37Cl, and 87Sr studies to assess groundwater flow and solute sources in the southwestern Great Artesian Basin, Australia

    International Nuclear Information System (INIS)

    The Great Artesian Basin (GAB) is a water source for more than 200,000 residents in central Australia. This study investigates the relationship of bromine and chlorine stable isotopes to groundwater chemistry in a confined aquifer in the southwestern GAB to better understand its flow regime and solute sources. δ81Br values range from +0.660/00 near the recharge area to +1.04 0/00, 150 km down gradient, while δ37Cl ranges from 00/00 to -2.50/00. While δ37Cl decreases with distance from the recharge area, δ81Br increases slightly. Bromide in the recharge area is possibly enriched from selective atmospheric processes causing fractionation in marine aerosols during transport. When confined and isolated from the atmosphere, increases in bromide and to a lesser extent strontium concentrations may contribute through water-rock interaction to changes in isotopic signatures along the flow system. 87Sr/86Sr values range from ∼0.717 near the recharge zone to a depleted 0.708 160 km down gradient.

    SummaryWater flow and solute transport in soils forms an essential part in many groundwater hydrology studies. This is especially true for Northeast Thailand, where the agricultural land is affected by the soil salinity, which is a widespread and an increasing phenomenon affecting 25% of the agricultural land. Salinization appears as scattered discrete patches of 10-100 m2 in the lowlands, illustrated by white efflorescences during the dry season and bare soil during the cropping season. A field study was undertaken in farm plots to measure the water flow and solute transport within the soil surface and the vadose zone, both inside and outside a saline patch. The water flow was measured on the soil surface with lysimeters and infiltration rings, and was derived in the soil from the hydraulic gradients measured with tensiometers placed at different depths. The salt transport was evaluated with water traps also placed at different depths, where the soil water's electrical conductivity was measured throughout the rainy season. Field study results demonstrated that the accumulation of saline solutions in rain fed paddy fields, occurred mainly during the rainy season while the soil surface remained flooded. During this period the saline water table rose towards the soil surface independently of infiltration into the soil. It happened in specific places where the compacted soil layer, generally ubiquitous in the area at a depth of 40-50 cm, is interrupted. Therefore salinity appeareds in discret points as patches. Artesian upward flow already described in this area (Haworth et al., 1966; Williamson et al., 1989; Imaizumi et al., 2002) is most probably responsible for this water table rise, thereby affecting crop productivity. Numerical modelling of water flow using HYDRUS-3D further supported these results and showed that managing the depth of flooding within the plot can significantly reduce the outbreak of these saline plumes.

  13. Using environmental isotopes and dissolved methane concentrations to constrain hydrochemical processes and inter-aquifer mixing in the Galilee and Eromanga Basins, Great Artesian Basin, Australia

    2016-08-01

    Groundwater recharge processes, water-rock interaction and the hydraulic connectivity between aquifers of the Galilee and Eromanga Basins in central Queensland, Australia, were investigated using stable (δ2H, δ18O, δ13C and 87Sr/86Sr) and radiogenic (36Cl) isotopes and dissolved methane concentrations, complemented by major ion chemistry. The central Eromanga and the upper sequence of the Galilee basins are both sub-basins of the Great Artesian Basin (GAB), and the coal seams of the Galilee Basin are currently explored for their potential as commercial coal seam gas deposits. In order to understand the potential influence of depressurisation of coal seams required to release the gas on adjacent aquifers, a detailed understanding of recharge processes and groundwater hydraulics of these basins prior to any development is required. Each of the different isotope systems were used in this study to provide different information on specific processes. For example, the assessment of δ13C and 87Sr/86Sr ratios suggested that carbonate dissolution is one of the major processes controlling the water chemistry within some aquifers. In addition, the combined assessment of δ2H, δ18O and major ion chemistry indicates that transpiration is the primary process controlling the solute concentration in the GAB recharge area, whereas evaporation appears to be less significant. Groundwaters in the Galilee Basin recharge area (outside the limits of the GAB) are different to any groundwater within the GAB units. This difference is attributed to the dissolution of potassium-bearing micas, which are absent in the GAB. Groundwater age estimates based on 36Cl/Cl ratios suggest that there is a steady increase along the flow paths, and this lack of anomalous age estimates from the recharge areas to the deeper parts of the basin indicates that there is no evidence for regional inter-aquifer mixing based in isotopes only. However, dissolved methane concentrations and groundwater chemistry

    The results of drilling test holes to depths of approximately 1,000 feet in the Mud Lake region show that a large part of the region is underlain by both sedimentary deposits and basalt flows. At some locations, predominantly sedimentary deposits were penetrated; at others, basalt flows predominated. The so-called Mud Lake-Market Lake barrier denotes a change in geology. From the vicinity of the barrier area, as described by Stearns, Crandall, and Steward (1938, p. 111), up the water-table gradient for at least a few tens of miles, the saturated geologic section consists predominantly of beds of sediments that are intercalated with numerous basalt flows. Downgradient from the barrier, sedimentary deposits are not common and practically all the water-bearing formations are basalt, at least to the depths explored so far. Thus, the barrier is a transition zone from a sedimentary-basaltic sequence to a basaltic sequence. The sedimentary-basaltic sequence forms a complex hydrologic system in which water occurs under water-table conditions in the upper few tens of feet of saturated material and under artesian conditions in the deeper material in the southwest part of the region. The well data indicate that southwest of the barrier, artesian pressures are not significant. Southwest of the barrier, few sedimentary deposits occur in the basalt section and, as described by Mundorff, Crosthwaite, and Kilburn (1964). ground water occurs in a manner typical of the Snake Plain aquifer. In several wells, artesian pressures are higher in the deeper formations than in the shallower ones, but the reverse was found in a few wells. The available data are not adequate to describe the water-bearing characteristics of the artesian aquifer nor the effects that pumping in one zone would have on adjacent zones. The water-table aquifer yields large quantities of water to irrigation wells.

    Watkins, Frank A., Jr.

    1977-01-01

    A connector well pilot installation, in continuous operation in western Orange County since December 4, 1970, was transferring water from the lower of two shallow sand aquifers to the Floridan aquifer at a rate of 13 gallons per minute when measured on September 23, 1971. The recharge water is untreated and analyses show it to be chemically and physically compatible with the water in the Floridan aquifer. The temperatures of the recharging and receiving waters were identical, 23 deg C. The transfer of water from the lower sand aquifer to the Floridan aquifer caused only a small buildup of artesian pressure in the Floridan aquifer but it lowered the artesian head 4 feet in the lower sand aquifer near the well which supplied the recharge water. Water levels in the upper sand aquifer were not affected, probably because of the low permeability of an intervening hardpan layer. However, after six auger holes back-filled with sand connected the two sand aquifers on April 5, 1972, a rise of water levels in the lower sand aquifer was noted. The principal chemical and physical effects on the water in the Floridan aquifer were a general improvement in chemical quality and an increase in color. The color may decrease as more water moves through the sand aquifer and the material responsible for the high color is removed by flushing. (Woodard-USGS)

    Unplugged abandoned oil and gas wells in the Appalachian region can serve as conduits for the movement of waters impacted by fossil fuel extraction. Strontium isotope and geochemical analysis indicate that artesian discharges of water with high total dissolved solids (TDS) from a series of gas wells in western Pennsylvania result from the infiltration of acidic, low Fe (Fe < 10 mg/L) coal mine drainage (AMD) into shallow, siderite (iron carbonate)-cemented sandstone aquifers. The acidity from the AMD promotes dissolution of the carbonate, and metal- and sulfate-contaminated waters rise to the surface through compromised abandoned gas well casings. Strontium isotope mixing models suggest that neither upward migration of oil and gas brines from Devonian reservoirs associated with the wells nor dissolution of abundant nodular siderite present in the mine spoil through which recharge water percolates contribute significantly to the artesian gas well discharges. Natural Sr isotope composition can be a sensitive tool in the characterization of complex groundwater interactions and can be used to distinguish between inputs from deep and shallow contamination sources, as well as between groundwater and mineralogically similar but stratigraphically distinct rock units. This is of particular relevance to regions such as the Appalachian Basin, where a legacy of coal, oil and gas exploration is coupled with ongoing and future natural gas drilling into deep reservoirs.

  17. Environmental implications of a gas well blowout in northwest Louisiana - A case study

    International Nuclear Information System (INIS)

    Oil and gas exploration in northern Louisiana has been ongoing since the 1920s. During this time occasional blowouts have occurred which have impacted the environment. In March, 1994, a Sligo Field well experienced an unusual blowout in that the event propagated to the surface through an adjacent abandoned well. While drilling through the fractured Thompson-Pettet interval at a depth of 5000 feet, a pressure kick, caused by a loss of drilling fluids, occurred. The well control devices activated and prevented loss of the well. However, the pressure front moved up the well's uncased annulus until reaching the base of the cemented surface casing where it dispersed laterally in the Nacatoch formation at a depth of approximately 1000 feet. This was the uppermost portion of the uncased hole. The pressure front propagated through the Nacatoch until it encountered the poorly cemented annulus of the abandoned Hardman No. 1 well, located approximately 300 feet to the south of the drilling location. After moving up the annulus of the Hardman No. 1 well and charging the fresh water sands of the Wilcox system, local residential water wells and the drilling rig's water supply well became flowing artesian. Several hours later sand and fluids began erupting, creating a large cavity on the outside of the casing surrounding the Hardman No. 1 well. The artesian impact lasted approximately four days until the pressure front dissipated. Subsequent sampling of the rig supply well determined the well to be contaminated with benzene, a known human carcinogen. The Louisiana Department of Environmental Quality, in conjunction with the operator, is currently investigating the extent of contamination with the goal of ensuring the health of the local residents and the protection of the environment

    Full Text Available In the developing phase of a hydrocarbon reservoir and planning for drilling the production wells, it is necessary to drill the wells in an appropriate spacing to achieve maximum economic revenues during the reservoir life span. Well spacing which is the real location and interrelationship between producing oil or gas wells in an oil field is an important parameter. It is determined for the maximum ultimate production of a given reservoir and should be taken in consideration during well planning to avoid drilling of unnecessary wells. This study presents the concept of drainage area on horizontal well and horizontal productivity indices with different equations and their applications. A user friendly Excel Spreadsheet program was developed to calculate the productivity values of horizontal wells using three major available productivity equations. Also, the developed spreadsheet program was used to evaluate the effect of well spacing on the productivities of horizontal wells using productivity index approach and drainage area concept. It also helps to review the comparison between vertical and horizontal wells spacing based on drainage area concept. This program was validated, and then was used to study the effect of horizontal well length on the ratio of horizontal well productivity to vertical well productivity. The results show that higher ratio of horizontal well productivity to vertical well productivity values are obtained with increase length of the horizontal well. It is a very useful tool for making decision about the application of well spacing for horizontal wells.

    Research core wells have been completed to assist in the characterization of the groundwater regime of the upper confined aquifers found within the basalts of the Hanford Site. These wells were drilled on the Hanford Site for the Long-Term Transuranic Defense Waste Program. They were constructed to assure the Department of Energy that waste management operations will not provide an avenue for offsite migration of radionuclides. This second report details results of confined aquifer drilling activities. The purpose of this report is to document the drilling history of the wells by presenting as-built well construction diagrams and tables listing hole history data, coring records and bit records. Four wells were cored to a maximum depth of 1100 feet and water samples were taken from selected confined aquifers. Full depth was reached on all wells and core recovery was 94% of all formations drilled. Well DB-8 was abandoned after a well screen was destroyed while setting it in the well. Two wells, DB-9 and DB-10 were screened in the Mabton interbed and water was produced from this interval in both wells. Well DB-11 was used to explore for artesian water from the Priest Rapids flow unit on the western edge of the Hanford Site. The water was found at a depth of 1045 feet and now produces makeup water for all Hanford drilling.

The indoor measurements of radon activity were performed using Solid State Nuclear Track Detectors CR-39. After the exposition, CR-39 detectors were submitted to chemical development which permitted to make alpha particle tracks counting. The results of calibration of CR-39 together with efficiency of used exhalation chambers as well as alpha particle tracks chemical development procedure were performed in cooperation with CDTN and collaboration with the National Institute of Radiological Sciences (NIRS). The major part of indoor {sup 222}Rn concentration in residences was found below 100 Bq/m3. In the case of working places, all measurements present {sup 222}Rn concentration bellow 100 Bq/m3. The studies of radon activity in water were performed using the samples of water from artesian wells submitted to recursive measurements by instant radon detector AlphaGUARD PQ2000 PRO during few weeks with intervals of about 4 days between each

    This paper presented the geotechnical conditions prevailing in the foundation of the Moncouche dyke. The 190 m long, 8.7 m high sand and gravel earth fill dyke is an important water retaining structure of the Kenogami lake reservoir. Following its first impoundment in 1924, heavy seepage forced the construction of a downstream pervious blanket and other remedial measures. During the 1996 July Saguenay flood, new seepage sources topped the blanket. This study analyzed the seepage in the foundation and simulated it through a 2D finite elements model in order to assess measures to reduce uplift seepage gradients. This paper described the modelling of the existing pore water pressures in the foundation. The pore pressures and seepage to be evacuated once the line of relief wells was in place were also estimated. They dyke's impervious core is a concrete wall connected at its lower end to a metal sheet piles driven to a variable depth. The existence of artesian conditions in the 30 m thick granular pervious fluvioglacial deposit combined with low to medium standard penetration tests and dynamic cone penetration test counts called for liquefaction hazard assessment relative to seismic loading. The construction of deep relief wells were shown to be an appropriate and cost effective measure to reduce seepage. 6 refs., 2 tabs., 13 figs.

  8. Isotopic fingerprinting of groundwaters in southwestern Ontario: Applications to abandoned well remediation

    International Nuclear Information System (INIS)

    Highlights: • We created a tool to predict sources of groundwaters leaking from abandoned wells. • Each of the main aquifers were characterized, for a total suite of over 130 samples. • 8 isotopes (δ18O, δ2H, δ34SSO4, δ18OSO4, δ13C, 87Sr/86Sr, δ37Cl and δ81Br) were analyzed. • Our tool well-predicted fluid origins in different real and hypothetical scenarios. • Leaking fluids from wells sampled so far were from a shallow Devonian aquifer. - Abstract: Southwestern Ontario has a legacy of unplugged oil and gas wells drilled in the late 1800s and early 1900s before the advent of government regulatory controls. A number of these wells exhibit artesian flow of salty and/or sulphurous water at the surface, creating a liability to landowners and a possible threat to potable groundwater aquifers and the surface environment. Cost-effective plugging of these wells is hindered by incomplete drilling records regarding well depths, well construction, and geologic information on the sources of the leaking fluids. This study seeks to fill this knowledge gap by characterizing distinct geochemical ‘fingerprints’ for each of the major bedrock water-producing zones that may be the possible sources of the leaking fluids. To this end, over 130 groundwater samples were collected and analyzed for a broad suite of isotopic parameters (δ18O, δ2H, δ34SSO4, δ18OSO4, δ13CDIC, 87Sr/86Sr, δ37Cl and δ81Br), and this dataset was combined with available data from previous studies in the area. A Bayesian mixing model, SIAR, was applied to these data to develop a statistical tool for identifying the probable source(s) of leaking fluids. Several hypothetical samples and one real-world example are presented here to demonstrate the model’s performance

    In the spring and summer of 1939 a program of exploratory drilling wad undertaken in the Houston district, Tx., in conjunction with a general initiation of the water resources of the district. The main purposes of the program were to determine the thickness and character of water-bearing sands down to a maximum depth of 2,000 feet, the chemical character of the water at different depths, and the artesian pressure and to provide additional observation wells for studying fluctuations in artesian pressure and possibilities of intrusion of salt water from the direction of the Gulf. Thirteen deep test wells, 5? inches in diameter and ranging in depth from 360 to 2,000 feet, were put down with a hydraulic rotary drill by the city of Houston. The combined drilling footage of all of the wells amounted to 17,460 feet, and their averse depth was 1,246 feet. All were electrically logged. Samples of cuttings were collected from the drilling mud after every 20 feet of drilling. In 6 of the wells sand samples were obtained by core drilling in beds at selected horizons, about 230 feet being recovered. A total of 15 samples of sand and water were obtained in 8 wells by the drill-stem method. Side-wall sampling was attempted. Six of the test holes were cased with 3? casing (inside diameter) and equipped with screens so that water-level measurements could be made and samples of water collected for chemical analyses , Selected sand samples were analyzed and tested in a field laboratory for mechanical composition, permeability, and porosity. The field and laboratory data were studied with special reference to the significance of the electrical logs. A comparison of the electrical logs of the test wells with the driller's logs shows that, on the whole, they agree remarkably well in fixing the upper and lower limits of the thicker beds of sand and clay, but that the agreement is not so close where the beds are thin. Variable results were obtained from attempts to correlate the second

  11. Alpha radioactivity monitoring related to Radon-222 in water from wells in metropolitan area of Curitiba (PR), Brazil

    International Nuclear Information System (INIS)

    This research objective was to assess the level of randon-222 concentration in well water of the metropolitan region of Curitiba, Parana. Current work presents the results of indoor 222Rn activity ground water samples from artesian wells from aquifers of the region. The studies of radon activity in water were performed using the radon detector AlphaGUARD. The calculations of initial radon activity in water were done considering the 222Rn decay correction as well as equilibrium level of 222Rn and 226Ra observed after 30 days of measurements. Obtained results show that about 70% of measured activity levels of 222Rn are higher than the recommended value of 11.1 Bq.L-1, which represent the risk for the human health associated with this radionuclide. The case study showed that previous measurements of radon are recommended for a construction project is implemented. In this case, it is observed that the radon concentrations decrease about 56% in the first water tank and 83% in the second water tank over the well. This fact shows that the actions for mitigation of radon are viable and do not require major modifications to the usual systems of construction. (author)

    This study presents the results of {sup 226}Ra and {sup 222}Rn activity concentration measurements in well water in the city of Curitiba - Parana State of Brazil. Water samples were collected from 31 wells and submitted to the radioactivity measurements in the Laboratory of Applied Nuclear Physics of the Federal University of Technology (UTFPR) in cooperation with CDTN-CNEN. Each water sample was submitted to 4 measurements of radon concentration with interval of three days. After two months the same samples were submitted once again to {sup 222}Rn concentration measurements with an objective to evaluate indirectly the amount of {sup 226}Ra contained in water samples. The {sup 222}Rn concentration measurements were performed using AlphaGUARD radon monitor (Genitron Instruments) and {sup 226}Ra concentration was evaluated using the decay curves of {sup 222}Rn. Within few hours after extraction about 70% of water samples from monitored wells presented {sup 222}Rn concentration values above the limit of 11.1 Bq/L recommended by the USEPA. Obtained activity values varied between 1.57 Bq/L - 215.16 Bq/L for radon concentration, and radium concentrations deviated within an interval of 0.61 Bq/L - 6.76 Bq/L. Obtained results showed that the biggest part of {sup 222}Rn found in water samples was not originated from the {sup 226}Ra compounds soluble in water but from gas exhalation by the soil adjacent to the well. The results of present research show the requirement of radioactivity monitoring of water extracted from artesian wells at Curitiba region and indicate the necessity of mitigation procedure development for better control of global alpha radioactivity in drinking water.

  13. Implementation of field techniques to stabilize abandoned oil wells - Boyd's creek, Kentucky

    International Nuclear Information System (INIS)

    At Boyd's Creek, commercial crude-oil drilling production began in the early 1860s. Countless unrecorded exploration wells were drilled and many have been found to be improperly abandoned. The Corniferous limestone is the first oil producing interval and is situated at an average subsurface depth of 135 feet. The potential for impacting natural resources is high because of the shallow depth(s) of the Corniferous limestone and the presence of overlying artesian sulfur-water zones which routinely mix with brine and oil in uncased boreholes. The occurrence of limestone related (karstic) features, such as fractures and dissolution cavities, and the close proximity of the Boyd's Creek oil field to nearby surface streams are also of concern. Initially, two abandoned wells were identified as flowing into nearby streams. Pursuant to federal removal authority provided by Subsection (c) of Section 311 of the Federal Water Pollution Control Act in accordance with Subtitle B of the Oil Pollution Act of 1990 and the National Contingency Plan, the Environmental Protection Agency has initiated cleanup operations within properties nearest to Boyd's Creek. Most wells are difficult to identify because they lack any casing strings and/or they have been buried with soil to hide uncontrolled flows at the surface. Field operations have included the utilization of multiple geophysical techniques to identify anomaly areas thought to represent buried unplugged wells. These include the excavation of surface soils down to the underlying limestone bedrock to search for cable tool and rotary boreholes, the drilling out of old wells using conventional industry technology and standards to plug them permanently with cement, the construction of temporary underflow dams downgradient from identified oil spills to minimize impacts on Boyd's Creek and its adjoining tributaries, and the burning of spilled product in temporary holding pits to minimize associated cleanup cost

    1987-01-01

    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.

  3. Dry well cooling device

    International Nuclear Information System (INIS)

    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.)

  4. A solvable double well

    Mohammedi, N

    2016-01-01

    We study the quantum behaviour of a particle moving in a one-dimensional double well potential. This double well is obtained by gluing together, at the origin, two shifted harmonic oscillator potentials. The Schr\\"odinger equation is exactly solvable. The requirement that discontinuities, in the wavefunction and its first derivative, are absent at the origin, leads to the quantisation of the energy eigenvalues. We also show that oscillations in time take place between two nearby single harmonic oscillator ground states. Finally, the double well potential is augmented by a Dirac delta-function potentials at the origin and the corresponding Schr\\"odinger equation is solved.

    The stimulation of geothermal wells presents some new and challenging problems. Formation temperatures in the 300-600 F range can be expected. The behavior of stimulation fluids, frac proppants, and equipment at these temperatures in a hostile brine environment must be carefully evaluated before performance expectations can be determined. In order to avoid possible damage to the producing horizon of the formation, high temperature chemical compatibility between the in situ materials and the stimulation materials must be verified. Perhaps most significant of all, in geothermal wells the required techniques must be capable of bringing about the production of very large amounts of fluid. This necessity for high flow rates represents a significant departure from conventional petroleum well stimulation and demands the creation of very high near-wellbore permeability and/or fractures with very high flow conductivity.

    2000-07-01

    This new Handbook is designed to give a complete, comprehensive overview of field development and well production, providing a wealth of practical information. It is intended as a reference guide for petroleum engineers and oil field operators, yet also provides readily-available solutions to practical problems. The user will find the guidelines, recommendations, formulas and charts currently in use, as it covers most of the cases encountered in the field. Even when a problem has been contracted out to a service company, reference to this handbook will help the oil field manager to better monitor out-sourced work and current operations. The handbook also introduces the new techniques of well production (horizontal and multilateral wells, heavy oil production, etc.). Many examples are given throughout to facilitate the use of the formulas. Also, measurements are frequently expressed in both metric and U.S. units. The symbols used for these units conform to the recommendations of the SPE Board of Directors. This publication will therefore serve both as a guide and as a handbook, in which the operator will find answers to his questions, along with quick and easy solutions to most of the problems that occur in field development. Contents: General data. Casing and tubing. Coiled tubing. Packers. Pressure losses. Fundamentals of petroleum reservoirs. Well productivity. Formation damage control. Sand control. Stimulation.

    2014-10-01

    Physician health and wellness is a critical issue gaining national attention because of the high prevalence of physician burnout. Pediatricians and pediatric trainees experience burnout at levels equivalent to other medical specialties, highlighting a need for more effective efforts to promote health and well-being in the pediatric community. This report will provide an overview of physician burnout, an update on work in the field of preventive physician health and wellness, and a discussion of emerging initiatives that have potential to promote health at all levels of pediatric training. Pediatricians are uniquely positioned to lead this movement nationally, in part because of the emphasis placed on wellness in the Pediatric Milestone Project, a joint collaboration between the Accreditation Council for Graduate Medical Education and the American Board of Pediatrics. Updated core competencies calling for a balanced approach to health, including focus on nutrition, exercise, mindfulness, and effective stress management, signal a paradigm shift and send the message that it is time for pediatricians to cultivate a culture of wellness better aligned with their responsibilities as role models and congruent with advances in pediatric training. Rather than reviewing programs in place to address substance abuse and other serious conditions in distressed physicians, this article focuses on forward progress in the field, with an emphasis on the need for prevention and anticipation of predictable stressors related to burnout in medical training and practice. Examples of positive progress and several programs designed to promote physician health and wellness are reviewed. Areas where more research is needed are highlighted. PMID:25266440

    International Nuclear Information System (INIS)

    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)

    This is a downhole gas and air burner for use in wells to stimulate production. The combustible mixture is supplied to the combustion chamber of the downhole burner through a delivery tube. This tube includes a flow-back preventer and a check valve. The flashback preventers consist of a porous material which has restricted flow paths. The check valve controls the flow of combustible mixture to the combustion chamber and prevents undesirable pulsating flow through the combustion chamber and the delivery tube. The check valve also prevents flooding of the combustion chamber by well fluid. The burner is ignited electrically. The porous material can be flat strip or a conically shaped piece of thin porous metal.

    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.

    Full Text Available The aim of this work was to study the occurrence of Aeromonas sp in the bottled mineral water, well water and tap water from the municipal supplies. Positive samples were found for Aeromonas spp. 12.7% from the mineral water, 8.3% from the artesian water and 6.5% from the tap water. The recovery of Aeromonas spp. was significantly higher in the bottled mineral and artesian water than in the tap water from municipal supplies. The occurrence of the Aeromonas spp. did not correlate significantly with the contamination indicator bacteria (i.e. total coliforms in the artesian water samples. However, a significant correlation was found between Aeromonas spp. and total coliforms in the both mineral water and tap water samples. The presence or absence of a correlation between the indicator bacteria and Aeromonas could reflect the occasional appearance of the pathogen in the drinking water and the different rates of survival and recovery of these agents compared with those fecal indicators. The finding that 41.6, 14.8 and 9.0 % of the artesian water, bottled mineral water and tap water, respectively, sampled in the current study failed to meet the Brazilian standard for total coliforms in the drinking water should therefore be of concern.A porcentagem de amostras positivas para Aeromonas foi de 12.7% para água mineral, 8.3% para água de poço artesiano e 6.5% para água do sistema público de abastecimento. O isolamento de Aeromonas spp. foi significativamente maior em água mineral e água de poço artesiano do que em água do sistema público.

    This research objective was to assess the level of randon-222 concentration in well water of the metropolitan region of Curitiba, Parana. Current work presents the results of indoor {sup 222}Rn activity ground water samples from artesian wells from aquifers of the region. The studies of radon activity in water were performed using the radon detector AlphaGUARD. The calculations of initial radon activity in water were done considering the {sup 222}Rn decay correction as well as equilibrium level of {sup 222}Rn and {sup 226}Ra observed after 30 days of measurements. Obtained results show that about 70% of measured activity levels of {sup 222}Rn are higher than the recommended value of 11.1 Bq.L{sup -1}, which represent the risk for the human health associated with this radionuclide. The case study showed that previous measurements of radon are recommended for a construction project is implemented. In this case, it is observed that the radon concentrations decrease about 56% in the first water tank and 83% in the second water tank over the well. This fact shows that the actions for mitigation of radon are viable and do not require major modifications to the usual systems of construction. (author)

  13. Pressure analysis for horizontal wells

    Energy Technology Data Exchange (ETDEWEB)

    Spivak, D.

    1988-01-01

    This study deals with the solution for pressure response of horizontal wells in three different anisotropic media: the infinite reservoir, the limited reservoir and the reservoir with constant pressure at the outer boundaries. Pressure analyses for vertical wells in various reservoirs are abundant, but there has been no comprehensive study of pressure analysis for horizontal wells in these three media. The objectives of this work are to examine and to determine the likely effects of horizontal wells on productivity and on the integration of pressure tests. The method of images, the concept of instantaneous sources and the Newman product method have been used. Integration of the summed source functions is achieved numerically using Simpson's rule. All three solutions are semi-analytical and have been verified and validated. For the infinite reservoir the solution has been compared to a directional well of high angle, and long horizontal well responses have been compared to the solution for the uniform-flux vertical fracture. The solutions to the other two cases (for long horizontal wells) have been compared to published solutions for uniform-flux vertical fractures. New equations, new pseudo-skin factors, new type curves, and new shape factors have been generated in the course of this work. The log-log type curves can be used to determine reservoir characteristics. The influences of different well and reservoir parameters on the well productivity have been investigated and are presented to show the merits of horizontal wells. A major features of this study is that some portions are presented here for the first time.

    2003-01-01

    The calculation of productivity and the choice of well pattern of mixed horizontal and vertical wells were discussed in this paper. Because the naturall drainage areas of horizontal wells are oval rather than circular, rectangular drainage well patterns should be adopted. Using pseudo 3-dimensional method and conformal transformation, the potential function of a row of horizontal wells was deduced. Using this function and the superposition principle, an analytical solution of the productivity for the rectangular mixed well pattern was given. Quantitative means for defining the shapes of the optimum pattern were developed in this paper by introducing two dimensionless parameters, the shape factor and dimensionless length of horizontal well. The formula for productvity was used to optimize the mixed well patterns. The curves of the optimized shape factor against dimensionless length of horizontal well were drawn. The results show that the pattern area and formation thickness have no effect on the optimal shape factors and can be applied to the design of development for oil fields.

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

    2004-09-01

    The basic operational goal in the petroleum industry is to produce maximum oil with minimum expense over an optimal time to maximize netback. During the decade of the 1990s the heavy oil industry in the Lloydminster area reduced operating expenses from $12/bbl to $7.00/bbl largely through conversion to progressive cavity pumps, several micro-engineering advances in handling and disposing of sand, in developing better workovers and methods, and in refining details of well design. Currently, over 600,000 bbl/day of heavy oil are produced in Canada using the CHOPS (cold heavy oil production with sand) technology. CHOPS requires sand flux; without sand, oil rates drop to uneconomic levels in viscous oil wells. Conversely, encouraging sand influx and dealing with it appropriately, can result in substantial increases in oil rates. This article reviews the causes of reduced well production (mechanical, well blockage, near-field and far-field root causes) and the types of workovers that are most appropriate for use, depending upon the cause. A staged-approach to well workover to minimize risk is also explained. A cost-benefit formula is also recommended, i.e. a workover is considered to have been successful if it pays for its costs plus reduces operating expenses in the 90-day period after the well is returned to production.

  6. Well fracturing with produced water

    International Nuclear Information System (INIS)

    Well fracturing with produced water was discussed with particular reference to fracturing basics such as formation rock, notably sandstone, carbonate, coal, and shale; accumulation of oil and gas; and surface operations. Several illustrations were provided. Issues regarding horizontal wells were also discussed with reference to the reasons behind drilling horizontal wells and the reasons for longitudinal and transverse fracs. Issues regarding the volume of frac water were also outlined. Fluid selection criteria were outlined in terms of formation rock compatibility; cleanup; pumping pressures; safety requirements; proppant transport; viscosity; and economics. Water is considered to be the best fluid choice for most fracture treatments because it is cheap, safe, environmentally friendly, widely available and very compatible with surface facilities. Water issues were also discussed. It was concluded that water conservation targets have been met, with higher profits. tabs., figs.

    Science.gov (United States)

    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.

    Full Text Available The interest and performance of horizontal drilling and completions has increased during the last two decades. Horizontal wells are advantageous compared to vertical wells in thin reservoirs, reservoirs with favorable vertical permeability and reservoirs with water and gas coning problems. In many reservoirs, the ratio of horizontal permeability to the vertical permeability is substantially larger than one and often is close to 10. Thus, these reservoirs are very good candidates for hydraulic fracturing. By hydraulic fracturing one or more fractures are created, which can be longitudinal or orthogonal. By that, flow is altered and it mostly conducts horizontally through reservoir toward horizontal wellbore. With this altered flow, fluid is produced faster, with less pressure loss by fluid unit of produced fluid. Some of the existing mathematical models to determine the productivity of multifractured horizontal wells are presented in this work (the paper is published in Croatian.

  9. Well drilling summary report for well 199-N-106A

    International Nuclear Information System (INIS)

    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 90Sr 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. This document is a compilation of the data collected during the drilling of well 199-N-106A, an extraction well for the 100-N Pump-and-Treat Project

  12. ADVANCED CEMENTS FOR GEOTHERMAL WELLS

    Energy Technology Data Exchange (ETDEWEB)

    SUGAMA,T.

    2007-01-01

    Using the conventional well cements consisting of the calcium silicate hydrates (CaO-SiO{sub 2}-H{sub 2}O system) and calcium aluminum silicate hydrates (CaO-Al{sub 2}O{sub 3}-SiO{sub 2}-H{sub 2}O system) for the integrity of geothermal wells, the serious concern confronting the cementing industries was their poor performance in mechanically supporting the metallic well casing pipes and in mitigating the pipe's corrosion in very harsh geothermal reservoirs. These difficulties are particularly acute in two geological regions: One is the deep hot downhole area ({approx} 1700 m depth at temperatures of {approx} 320 C) that contains hyper saline water with high concentrations of CO{sub 2} (> 40,000 ppm) in conjunction with {approx} 100 ppm H{sub 2}S at a mild acid of pH {approx} 5.0; the other is the upper well region between the well's surface and {approx} 1000 m depth at temperatures up to 200 C. The specific environment of the latter region is characterized by highly concentrated H{sub 2}SO{sub 4} (pH < 1.5) brine containing at least 5000 ppm CO{sub 2}. When these conventional cements are emplaced in these harsh environments, their major shortcoming is their susceptibility to reactions with hot CO{sub 2} and H{sub 2}SO4, thereby causing their deterioration brought about by CO{sub 2}-catalyzed carbonation and acid-initiated erosion. Such degradation not only reduced rapidly the strength of cements, lowering the mechanical support of casing pipes, but also increased the extent of permeability of the brine through the cement layer, promoting the rate of the pipe's corrosion. Severely carbonated and acid eroded cements often impaired the integrity of a well in less than one year; in the worst cases, casings have collapsed within three months, leading to the need for costly and time-consuming repairs or redrilling operations. These were the reasons why the geothermal well drilling and cementing industries were concerned about using conventional well

    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.

Afler the analysis of the peculiarities of horizontal wells and drainholes drilling techniques, advantages and disadvantages of the application of both roller cone and fixed cutters drill bits have been discussed. Also, a review of the potential specific featuries useful for a correct drill bit selection in horizontal small diameter holes has been highlighted. Drill bits for these special applications, whose importance is quickly increasing nowadays, should be characterised by a design capable to deliver a good penetration rate low WOB, and, at the same time, be able to withstand high RPM without premature cutting structure failure and undergauge. Formation properties will also determine the cutting structure type and the eventual specific features for additional gauge and shoulder protection.

    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.

    The fundamental efficiency limit of a single bandgap solar cell is about 31% at one sun with a bandgap of about Eg = 1.35 eV (1), determined by the trade-off of maximising current with a smaller bandgap and voltage with a larger bandgap. Multiple bandgaps can be introduced to absorb the broad solar spectrum more efficiently. This can be realised in multi- junction cells, for example, where two or more cells are stacked on top of each other either mechanically or monolithically connected by a tunnel junction. An alternative or complementary (see section 1.4) approach is the quantum well cell (QWC).

    Resonance dielectric response of excitons is studied for the high-quality InGaAs/GaAs heterostructures with wide asymmetric quantum wells (QWs). To highlight effects of the QW asymmetry, we have grown and studied several heterostructures with nominally square QWs as well as with triangle-like QWs. Several quantum confined exciton states are experimentally observed as narrow exciton resonances. A standard approach for the phenomenological analysis of the profiles is generalized by introducing different phase shifts for the light waves reflected from the QWs at different exciton resonances. Good agreement of the phenomenological fit to the experimentally observed exciton spectra for high-quality structures allowed us to reliably obtain parameters of the exciton resonances: the exciton transition energies, the radiative broadenings, and the phase shifts. A direct numerical solution of the Schrödinger equation for the heavy-hole excitons in asymmetric QWs is used for microscopic modeling of the exciton resonances. Remarkable agreement with the experiment is achieved when the effect of indium segregation is taken into account. The segregation results in a modification of the potential profile, in particular, in an asymmetry of the nominally square QWs.

  19. Silicon Germanium Quantum Well Thermoelectrics

    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

    This project has enabled Hi-Z technology Inc. (Hi-Z) to understand how to improve the thermoelectric properties of Si/SiGe Quantum Well Thermoelectric Materials. The research that was completed under this project has enabled Hi-Z Technology, Inc. (Hi-Z) to satisfy the project goal to understand how to improve thermoelectric conversion efficiency and reduce costs by fabricating ultra thin Si/SiGe quantum well (QW) materials and measuring their properties. In addition, Hi-Z gained critical new understanding on how thin film fabrication increases the silicon substrate's electrical conductivity, which is important new knowledge to develop critical material fabrication parameters. QW materials are constructed with alternate layers of an electrical conductor, SiGe and an electrical insulator, Si. Film thicknesses were varied, ranging from 2nm to 10nm where 10 nm was the original film thickness prior to this work. The optimum performance was determined at a Si and SiGe thickness of 4nm for an electrical current and heat flow parallel to the films, which was an important conclusion of this work. Essential new information was obtained on how the Si substrate electrical conductivity increases by up to an order of magnitude upon deposition of QW films. Test measurements and calculations are accurate and include both the quantum well and the substrate. The large increase in substrate electrical conductivity means that a larger portion of the electrical current passes through the substrate. The silicon substrate's increased electrical conductivity is due to inherent impurities and thermal donors which are activated during both molecular beam epitaxy and sputtering deposition of QW materials. Hi-Z's forward looking cost estimations based on future high performance QW modules, in which the best Seebeck coefficient and electrical resistivity are taken from separate samples predict that the electricity cost produced with a QW module could be achieved at <$0.35/W

  2. Spin photocurrents in quantum wells

    CERN Document Server

    Ganichev, S D

    2003-01-01

    Spin photocurrents generated by homogeneous optical excitation with circularly polarized radiation in quantum wells (QWs) are reviewed. The absorption of circularly polarized light results in optical spin orientation due to the transfer of the angular momentum of photons to electrons of a two-dimensional electron gas. It is shown that in QWs belonging to one of the gyrotropic crystal classes a non-equilibrium spin polarization of uniformly distributed electrons causes a directed motion of electrons in the plane of the QW. A characteristic feature of this electric current, which occurs in unbiased samples, is that it reverses its direction upon changing the radiation helicity from left-handed to right-handed and vice versa. Two microscopic mechanisms are responsible for the occurrence of an electric current linked to a uniform spin polarization in a QW: the spin polarization-induced circular photogalvanic effect and the spin-galvanic effect. In both effects the current flow is driven by an asymmetric distribut...

    In addition to intervening when workers have substance abuse or stress problems, many hospital employee assistance programs (EAPs) now include a wellness component that emphasizes prevention and organizational wholeness. The EAP at St. Joseph's Hospital & Medical Center, Paterson, NJ, has taken a number of steps to improve its responsiveness to employees' needs and promote constructive organizational changes. To meet increasing requests for mental health services, St. Joseph's EAP implemented a short-term (up to 12 sessions) counseling program that focuses on problem-solving techniques. The EAP has also used feedback from clients to address organizational issues. For example, a survey that revealed differences between managers' and employees' perceptions of managers' leadership skills has led St. Joseph's to consider development of further workshops to train managers on how to be more effective leaders. And in response to complaints from nurses about a lack of communication with physicians, St. Joseph's invested $8,000 to implement nursing support groups and seminars to enhance nurse-physician collaboration. Additional EAP activities include consulting services for other corporations and help for employees in overcoming financial barriers to access to healthcare and social services. As budgets tighten, effective marketing of EAPs will be essential to their continued growth. In particular, EAP administrators must learn how to document the strategic and financial benefits of their programs. PMID:10127981

Background limited infrared performance (BLIP) operations are observed for all samples (three in total) ,designed for different wavelengths. BLIP temperatures of 17,13, and 12K are achieved for peak detection frequencies of 9.7THz(31μm) ,5.4THz(56μm) ,and 3.2THz(93μm) ,respectively. A set of THz quantum-cascade lasers with identical device parameters except for doping concentration is studied. The δ-doping density for each period varies from 3.2 × 1010 to 4. 8 × 1010cm-2. We observe that the lasing threshold current density increases monotonically with doping concentration. Moreover, the measurements for devices with different cavity lengths provide evidence that the free carrier absorption causes the waveguide loss also to increase monotonically. Interestingly the observed maximum lasing temperature is best at a doping density of 3.6 × 1010cm-2.

    The AT&T/Rockwell team met all the objectives of this collaborative program; AT&T supplied the QWIP detector arrays and Rockwell subsequently fabricated hybrid focal plane arrays using available high performance CMOS multiplexers, tested the hybrids, performed breadboard imaging demonstrations and delivered several hybrid FPA's. Eighteen hybrids were fabricated and evaluated. The collaboration yielded significant improvements in QWIP FPA performance and reliability and many milestones including: first BLIP LWIR FPA sensitivity demonstration at low photon backgrounds (less than 1 x 10(exp 12) photons/sq cm-sec) with the GaAs-based quantum well infrared photodetector (QWIP) technology, high LWIR FPA pixel operability; NE Delta T's as low as 5 mK at LWIR imaging backgrounds at f/1.4 and temperatures consistent with mechanical coolers (approx. 65K), increased coupling efficiency by over an order of magnitude; achieved effective quantum efficiency of approx. 10% with low crosstalk; effective quantum efficiencies of up to 30% under flood illumination, though with high crosstalk; mean D* of 1 x10(exp 14) cm-Hz(exp 1/2)/W at 3.0 x 10(exp 9) photons/sq cm-sec background at 32.5K operating temperature with greater than 98% operability; maximum temperature for 9.5 microns m FPA BLIP sensitivity as high as 62K; excellent hybrid reliability by mechanically thinning the QWIP; and responsivity nonuniformity less than 3% rms, thus enabling greater than 83 dB dynamic range.

    The birth of an infant is one of the most memorable experiences a family shares. Pediatric health care professionals are privileged to participate in this experience and recognize it as a time to promote the health of the newborn and family. Ideally, a well-designed care system would be replete with comprehensive supports during the prenatal period, birth, and transition to home. Opportunities exist to improve the care we deliver with universal screening of all pregnant women; coordinated assessments of family health, including mental health; and access to coordinated supports and services for mother and infant. If 90% of US families could comply with medical recommendations to breastfeed exclusively for 6 months, it is estimated the United States would save billions of dollars per year and prevent more than 900 deaths, nearly all of which would be in infants. All infants, whether breastfed or formula fed, should receive 400 IU supplemental vitamin D. Influenza and TdaP vaccination of postpartum mothers and other caregivers helps cocoon the vulnerable infant from influenza and pertussis until he or she can be fully vaccinated. When children reach the highest weight or length allowed by the manufacturer of their infant-only seat, they should continue to ride rear-facing in a convertible seat. It is best for children to ride rear-facing as long as possible to the highest weight and height allowed by the manufacturer of their convertible seat. PMID:22210929

    The concept of potential-energy diagrams is of fundamental importance in the study of quantum physics. Yet, students are rarely exposed to this powerful alternative description in introductory classes and thus have difficulty comprehending its significance when they encounter it in beginning-level quantum courses. We describe a learning unit that incorporates a sequence of computer-interfaced experiments using dynamics or air-track systems. This unit is designed to make the learning of potential-energy diagrams less abstract. Students begin by constructing the harmonic or square-well potential diagrams using either the velocity data and assuming conservation of energy or the force-displacement graph for the elastic interaction of an object constrained by springs or bouncing off springy blocks. Then, they investigate the motion of a rider magnet interacting with a configuration of field magnets and plot directly the potential-energy diagrams using a magnetic field sensor. The ease of measurement allows exploring the motion in a large variety of potential shapes in a short duration class.

    Full Text Available rising costs and risks in health care have shifted the preference of individuals from health treatment to disease prevention. This prevention treatment is known as wellness. In recent years, the Internet has become a popular place for wellness-conscious users to search for wellness-related information and solutions. As the user community becomes more wellness conscious, service improvement is needed to help users find relevant personalised wellness solutions. Due to rapid development in the wellness market, users value convenient access to wellness services. Most wellness websites reflect common health informatics approaches; these amount to more than 70,000 sites worldwide. Thus, the wellness industry should improve its Internet services in order to provide better and more convenient customer service. This paper discusses the development of a wellness recommender system that would help users find and adapt suitable personalised wellness therapy treatments based on their individual needs. This paper introduces new approaches that enhance the convenience and quality of wellness information delivery on the Internet. The wellness recommendation task is performed using an Artificial Intelligence technique of hybrid case-based reasoning (HCBR. HCBR solves users’ current wellness problems by applying solutions from similar cases in the past. From the evaluation results for our prototype wellness recommendation system, we conclude that wellness consultants are using consistent wellness knowledge to recommend solutions for sample wellness cases generated through an online consultation form. Thus, the proposed model can be integrated into wellness websites to enable users to search for suitable personalized wellness therapy treatment based on their health condition.

    Full Text Available This study describes a method of determining the position of adjacent well by analyzing geomagnetic anomalies in the drilling. In the experiment, put a casing in the geomagnetic field respectively to simulate 3 conditions, which are vertical well, deviated well and horizontal well. Study the interference of regional geomagnetic caused by casing, summary the law of the regional geomagnetic field anomalies caused by the adjacent casing. Experimental results show that: magnetic intensity distortion caused by deviated well is similar to that caused by horizontal well, but the distortion is different from vertical well. The scope and amplitude of N and E component magnetic intensity distortion will increase with the increase of casing inclination, meanwhile the scope and amplitude of V component distortion will decrease and the distortion value changes from negative to positive to the southwest of adjacent well. Through the analysis of geomagnetic anomalies, the position of the adjacent wells could be determined.

  16. Closure of shallow underground injection wells

    International Nuclear Information System (INIS)

    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

    2003-06-01

    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.

  16. Well integrity failure in the UK

    Science.gov (United States)

    Worrall, F.

    2015-12-01

    The aim of this study was to consider the potential legacy of increased onshore, unconventional gas production by examining the integrity of decommissioned, onshore, oil and gas wells in the UK. In the absence of a history of unconventional hydrocarbon exploitation in the UK, conventional onshore sites were considered and an examination of pollution incidents records had suggested that only a small fraction of operational, onshore wells could show integrity failures. A consideration of groundwater and surface water quality monitoring could find no regional impact of historic or current conventional oil and gas exploitation in the UK. As a more direct measure of well legacy this study considered the fugitive emissions of methane from former oil and gas wells onshore in the UK as a measure of well integrity. The survey considered 102 decommissioned (abandoned) wells from 4 different basins that were between 8 and 78 years old; all but one of these wells would be considered as having been decommissioned properly, i.e. wells cut, sealed and buried by soil cover to the extent that the well sites were being used for agriculture. For each well site the soil gas methane was analysed multiple times and assessed relative to a nearby control site of similar land-use and soil type. The results showed that of the 102 wells surveyed, 30% had soil gas CH4 at the soil surface that was significantly greater than their respective control. Conversely, 39% of well sites had significant lower surface soil gas CH4 concentrations than their respective control. We interpret elevated soil gas CH4 concentrations to be the result of well integrity failure, but do not know the source of the gas nor the route to the surface. Where elevated CH4 was detected it appears to have occurred within a decade of the well being decommissioned. The flux of CH4 from wells was 364 ± 677 kg CO2eq/well/yr with a 27% chance that any well would be a net sink of CH4 independent of well age. This flux is low

  19. Potential hydrologic characterization wells in Amargosa Valley

    International Nuclear Information System (INIS)

    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

    2014-01-01

    Horizontal wells covering entire length of the reservoirs are not economically suitable. Frictional pressure drops increases with the increase in well length and flow rates. Optimal Horizontal length is estimated through economic analysis i.e. Net present Value of the project (NPV). Well construction costs including incremental costs of drilling horizontal section, friction losses in horizontal section, Hydrocarbon prices and Drainage area affect NPV. This thesis work estimates NPV and Produc...

    Horizontal well technology has been widely used in petroleum and underground utility installation. Since late 1980's, the technology has been adapted for environmental remediation applications. Two general methods in drilling horizontal wells have been used in remediation, trenched and directionally-drilled. The first method involves the excavation of a relatively large diameter borehole, with simultaneous installation of well materials and backfill. The second method, directional drilling, p...

    This paper provides a review and critical discussion of indicators, which attempt to combine the measurement of sustainability with that of well-being. It starts with some commonly agreed definitions of sustainability, showing how most well-being indicators tell us little if anything at all about this issue. Sustainability is most commonly defined in economics as non-declining utility or well-being over time. Yet, due to its future orientation, most indicators of sustainability such as Genuin...

    Joseph A. Schumpeter's celebrated theory of creative destruction was anticipated by David Wells's Recent Economic Changes (1989). In some respects, Wells's treatment is superior to that of Schumpeter. Unlike Schumpeter, who believed that monopolistic competition could maximize economic growth, Wells held that cartels or trusts were necessary to prevent capital-intensive firms from competing themselves into bankruptcy and sending the economy into a depression.

    Some researchers have defined well-being as being content, happy, healthy and prosperous. It consists of experiencing enjoyment, completeness, and meaning, rather than merely avoiding pain and conflict. To experience personal well-being it is necessary that all aspects of being function in a healthy manner. Research on the relationship between the Christian religion and well-being has concluded that nurturing, non-punitive religion is associated with mental and physical health, and that activ...

    People have long argued over the relation of income and material well-being to happiness. A variety of studies have examined the happiness of those living at the lowest economic levels as well as those living in relatively affluent nations. Taken together, this body of research suggests that income is correlated with subjective well-being (SWB), but is neither the most important factor in happiness, nor is this relationship unmediated or context free.

    2010-01-01

    Arsenic concentrations can be managed with a relatively simple strategy of grouting instead of completely destroying a selected interval of well. The strategy of selective grouting was investigated in Antelope Valley, California, where groundwater supplies most of the water demand. Naturally occurring arsenic typically exceeds concentrations of 10 microg/L in the water produced from these long-screened wells. The vertical distributions of arsenic concentrations in intervals of the aquifer contributing water to selected supply wells were characterized with depth-dependent water-quality sampling and flow logs. Arsenic primarily entered the lower half of the wells where lacustrine clay deposits and a deeper aquifer occurred. Five wells were modified by grouting from below the top of the lacustrine clay deposits to the bottom of the well, which reduced produced arsenic concentrations to less than 2 microg/L in four of the five wells. Long-term viability of well modification and reduction of specific capacity was assessed for well 4-54 with AnalyzeHOLE, which creates and uses axisymmetric, radial MODFLOW models. Two radial models were calibrated to observed borehole flows, drawdowns, and transmissivity by estimating hydraulic-conductivity values in the aquifer system and gravel packs of the original and modified wells. Lithology also constrained hydraulic-conductivity estimates as regularization observations. Well encrustations caused as much as 2 microg/L increase in simulated arsenic concentration by reducing the contribution of flow from the aquifer system above the lacustrine clay deposits. Simulated arsenic concentrations in the modified well remained less than 3 microg/L over a 20-year period. PMID:20113363

  3. 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.

  6. Airlift recirculation well test results - Southern sector

    International Nuclear Information System (INIS)

    Chlorinated solvents used in the A and M-Areas at the Savannah River Site (SRS) from 1952--1982 have contaminated the groundwater under the site. A plume of groundwater contaminated with trichloroethylene (TCE) and perchloroethylene (PCE) in the Lost Lake aquifer is moving generally southward with the natural flow of groundwater. To comply with the requirements of the current SCDHEC Part B Permit, a series of wells is being installed to contain and treat the plume. Airlift Recirculation Wells (ARW) are a new and innovative technology with potential for more cost effective implementation than conventional pump and treat systems. Two Airlift Recirculation Wells have been installed and tested to quantify performance parameters needed to locate a line of these wells along the leading edge of the contaminant plume. The wells proved to be very sensitive to proper development, but after this requirement was met, performance was very good. The Zone of Capture has been estimated to be within a radius of 130--160 ft. around the wells. Thus a line of wells spaced at 250 ft. intervals could intercept the contaminant plume. At SSR-012, TCE was stripped from the groundwater at approximately 1.2 lb./day. The longer term effect of the recirculation wells upon the plume and the degree of recirculation within the aquifer itself will require additional data over a longer time period for an accurate review. Data collection is ongoing

  12. Conceptualising well-being for autistic persons.

    Robeyns, Ingrid

    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)?

  3. Geopressured-geothermal well activities in Louisiana

    International Nuclear Information System (INIS)

    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

    Full Text Available The objective of the study was to examine the relationships between several constructs that were hypothesised to be components underlying psychological wellness and to establish whether there were differences between managerial and non-managerial groups or between Black and White groups in respect of the wellness variables. The Personal Orientation Inventory (POI, Locus of Control Inventory (LOC, Sense of Coherence Scale (SOC, and the Bar-On EQ-I were administered to a random sample of 200 employees of a financial services company. Statistically significant differences were found between the groups on several of the wellness variables with the manager and White groups obtaining higher scores on these variables than their comparison groups. However, in respect of External Locus of Control, the non-manager and Black groups obtained the higher scores. Factor analytic results demonstrated that the wellness variables clustered in two correlated factors (r = 0,43 labeled psychological wellness and self-actualisation.

Based on a comparative project including ethnographies from Brazil, Uganda, Georgia and Denmark the authors discuss well-faring as a time-oriented process...... based on individual as well as societal conditions. The article argues that in order to understand well-faring it is important to analyse how visions and strategies for the future are shaped in relation to local circumstances. Whether it is possible to envision the future as hopeless or hopeful, as...... concrete or abstract or as dependent on family or state is a ma er of context. Well-faring is thus neither an individual nor a state project but must be analysed in a double perspective as an interplay between the two....

  7. Can Facebook use induce well-being?

    Science.gov (United States)

    Liu, Chia-Yi; Yu, Chia-Ping

    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. PMID:24028138

  8. Financial Well-being in Active Ageing.

    Rajola, Federico; Frigerio, Chiara; Parrichi, Monica

    2014-01-01

    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. PMID:26630513

  9. Groundwater monitoring for deep-well injection

    International Nuclear Information System (INIS)

    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

  10. Well test analysis in fractured media

    Karasaki, K.

    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.

  11. Well-being, capabilities and philosophical practice

    Directory of Open Access Journals (Sweden)

    Bulatović Aleksandra

    2014-01-01

    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.

  12. Solitons and vortices in nonlinear potential wells

    International Nuclear Information System (INIS)

    We consider self-trapping of topological modes governed by the one- and two-dimensional (1D and 2D) nonlinear-Schrödinger/Gross–Pitaevskii equation with effective single- and double-well (DW) nonlinear potentials induced by spatial modulation of the local strength of the self-defocusing nonlinearity. This setting, which may be implemented in optics and Bose–Einstein condensates, aims to extend previous studies, which dealt with single-well nonlinear potentials. In the 1D setting, we find several types of symmetric, asymmetric and antisymmetric states, paying attention to scenarios of the spontaneous symmetry breaking. The single-well model is extended by including rocking motion of the well, which gives rise to Rabi oscillations between fundamental and dipole modes. Analysis of the 2D single-well setting gives rise to stable modes in the form of ordinary dipoles, vortex–antivortex dipoles (VADs), and vortex triangles (VTs), which may be considered as produced by spontaneous breaking of the axial symmetry. The consideration of the DW configuration in 2D reveals diverse types of modes built of components trapped in the two wells, which may be fundamental states and vortices with topological charges m = 1 and 2, as well as VADs (with m = 0) and VTs (with m = 2).

    This study compares the effects of religiosity on health and well-being, controlling for work and family. With 2006 GSS data, we assess the effects of religiosity on health and well-being, net of job satisfaction, marital happiness, and financial status. The results indicate that people who identify as religious tend to report better health and happiness, regardless of religious affiliation, religious activities, work and family, social support, or financial status. People with liberal religious beliefs tend to be healthier but less happy than people with fundamentalist beliefs. Future research should probe how religious identity and beliefs impact health and well-being. PMID:19283486

  14. Automated seismic-to-well ties?

    CERN Document Server

    Herrera, Roberto Henry

    2012-01-01

    The quality of seismic-to-well tie is commonly quantified using the classical Pearson's correlation coefficient. However the seismic wavelet is time-variant, well logging and upscaling is only approximate, and the correlation coefficient does not follow this nonlinear behavior. We introduce the Dynamic Time Warping (DTW) to automate the tying process, accounting for frequency and time variance. The Dynamic Time Warping method can follow the nonlinear behavior better than the commonly used correlation coefficient. Furthermore, the quality of the similarity value does not depend on the selected correlating window. We compare the developed method with the manual seismic-to-well tie in a benchmark case study.

    The concept of well group in a special but important case captures homological properties of the zero set of a continuous map f from K to R^n on a compact space K that are invariant with respect to perturbations of f. The perturbations are arbitrary continuous maps within L_infty distance r from f for a given r > 0. The main drawback of the approach is that the computability of well groups was shown only when dim K = n or n = 1. Our contribution to the theory of well groups is twofold: on...

    2016-02-15

    Water Systems Council (WSC) is a national, non-profit organization providing education and resources to private household well owners. Since 2003, WSC has provided wellcare®, a toll-free telephone hotline to answer questions from the public regarding well stewardship. In order to identify knowledge gaps regarding well stewardship among private well owners, we obtained data from WSC and reviewed calls made during 2013 to wellcare®. WSC records data from each wellcare® call-including caller information, primary reason for call, main use of well water, and if they were calling about a cistern, private well, shared well, or spring. We searched for calls with key words indicating specific contaminants of interest and reviewed primary reasons for calls. Calls classified as primarily testing-related were further categorized depending on whether the caller asked about how to test well water or how to interpret testing results. During 2013, wellcare® received 1100 calls from private well owners who were residents of 48 states. Among these calls, 87 (8%) mentioned radon, 83 (8%) coliforms, 51 (5%) chemicals related to fracking, 34 (3%) arsenic, and 32 (3%) nitrates key words. Only 38% of private well owners reported conducting any well maintenance activities, such as inspecting, cleaning, repairing the well, or testing well water, during the previous 12 months. The primary reason for calls were related to well water testing (n=403), general information relating to wells (n=249), contaminants (n=229), and well water treatment (n=97). Among calls related to testing, 319 had questions about how to test their well water, and 33 had questions about how to interpret testing results. Calls from private well owners to the wellcare® Hotline during 2013 identified key knowledge gaps regarding well stewardship; well owners are generally not testing or maintaining their wells, have questions about well water testing treatment, and concerns about well water contaminants.

    International Nuclear Information System (INIS)

    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

  11. Evolving Definitions of Mental Illness and Wellness

    Tara W. Strine, MPH

    2010-01-01

    Full Text Available Understanding of the definitions of wellness and illness has changed from the mid-20th century to modern times, moving from a diagnosis-focused to a person-focused definition of mental illnesses, and from an “absence of disease” model to one that stresses positive psychological function for mental health. Currently, wellness refers to the degree to which one feels positive and enthusiastic about oneself and life, whereas illness refers to the presence of disease. These definitions apply to physical as well as mental illness and wellness. In this article, we build on the essential concepts of wellness and illness, discuss how these definitions have changed over time, and discuss their importance in the context of health reform and health care reform. Health reform refers to efforts focused on health, such as health promotion and the development of positive well-being. Health care reform refers to efforts focused on illness, such as treatment of disease and related rehabilitation efforts.

    This report provides analytical results for four groundwater-sampling rounds conducted at characterization well R-7. The goal of the characterization efforts was to assess the hydrochemistry and to determine if contaminants from Technical Area (TA)-2 and TA-21 of the Los Alamos National Laboratory (LANL or the Laboratory) are present in the regional aquifer in the vicinity of the well. Figure 1.0-1 shows the well's location in the narrow upper part of Los Alamos Canyon, between the inactive Omega West reactor and the mouth of DP Canyon. Well R-7 is in an excellent location to characterize the hydrology and groundwater chemistry in both perched groundwater and the regional aquifer near sites of known Laboratory effluent release, including radionuclides and inorganic chemicals (Stone et al. 2002, 72717). The Risk Reduction and Environmental Stewardship-Remediation (RRES-R) Program (formerly the Environmental Restoration [ER] Project) installed well R-7 as part of groundwater investigations to satisfy requirements of the ''Hydrogeologic Workplan'' (LANL 1998, 59599) and to support the Laboratory's ''Groundwater Protection Management Program Plan'' (LANL 1996, 70215). Well R-7 was designed primarily to provide geochemical or water quality and hydrogeologic data for the regional aquifer within the Puye Formation. This report also presents a geochemical evaluation of the analytical results for well R-7 and provides hydrogeochemical interpretations using analytical results for groundwater samples collected at the well. Discussion of other hydrogeochemical data collected within the east-central portion of the Laboratory, however, is deferred until they can be evaluated in the context of sitewide information collected from other RRES and Hydrogeologic Workplan characterization wells (R-8A, R-9, and R-9i).

    Sanchen Henning

    2012-01-01

    Full Text Available Orientation: The researchers constructed a Systems Psychodynamic Wellness Model (SPWM by merging theory and concepts from systems psychodynamics and positive psychology. They then refined the model for application in organisations during a Listening Post (LP that comprised experienced subject experts.Research purpose: The purpose of the research was to construct and refine the SPWM in order to understand psychological wellness at the individual, group and organisational levels.Motivation for the study: There is no psychological wellness model that integrates the principles of systems psychodynamics and positive psychology. Systems psychodynamics traditionally focuses on so-called negative behaviour whilst positive psychology tends to idealise positive behaviour. This research tried to merge these views in order to apply them to individual, group and organisational behaviour.Research design, approach and method: The researchers used qualitative, descriptive and conceptual research. They conducted an in-depth literature study to construct the model. They then refined it using the LP.Main findings: The researchers identified 39 themes. They categorised them into three different levels. Three first-level themes emerged as the highest level of integration: identity, hope and love. The nine second-level themes each consisted of three more themes. They were less complex and abstract than the first-level themes. The least complex 27 third-level themes followed.Practical/managerial implications: One can apply the SPWM as a qualitative diagnostic tool for understanding individual, group and organisational wellness and for consulting on systemic wellness.Contribution/value-add: The SPWM offers a model for understanding individual, group and organisational wellness and for consulting on systemic wellness.

  15. In situ bioremediation via horizontal wells

    International Nuclear Information System (INIS)

    The test consisted of methane mixed with air into the contaminated aquifer via a horizontal well and extraction from the vadose zone via a parallel horizontal well. This configuration has the advantage of simultaneously stimulating methanotrophic activity in both the groundwater and vadose zone, and inhibiting spread of the contaminant plume. Groundwater was monitored biweekly from 13 wells for a variety of chemical and microbiological parameters. Groundwater from wells in affected areas showed increases in methanotrophs of more than 1 order of magnitude every 2 weeks for several weeks after 1% methane-in-air injection was started. Some wells had increases as much as 7 orders of magnitude. Simultaneous with the increase in methanotrophs was a decrease in water and soil gas concentrations of trichloroethylene (TCE) and tetrachloroethane (PCE). Two wells declined in TCE/PCE concentration in the water by more than 90% to below 2 ppb. All of the wells in the affected zone showed significant decreases in contaminants in less than one month. Chloride concentrations in the water were inversely correlated with TCE/PCE concentration. Four of five vadose zone piezometers declined from concentration as high as 10,000 ppm to less than 5 ppm in less than 6 weeks. The fifth cluster also declined by more than 95%. After only three months on injection, a decline in TCE/PCE in the sediment of more than 30% was also observed, with TCE/PCE being undetectable in most sediments at the end of the 14-month test. Gene probes and direct isolation from the water and sediment revealed that the right types of methanotrophs were being stimulated and that isolates could degrade TCE at a high rate

  16. Helical Fields Possessing Mean Magnetic Wells

    International Nuclear Information System (INIS)

    Recently Furth and Rosenbluth pointed out that a particular magnetic field having helical symmetry could provide a mean magnetic well, that is provide regions in which ∫dℓ/B decreases away from a magnetic axis (or equivalently a region in which V'' is negative). In this paper we examine helical fields in general and the circumstances in which they may exhibit the negative V'' property. This investigation is made possible by the use of the stream function formalism which provides a simple picture of the field geometry, The existence of negative V'' is related to the topology of the magnetic surfaces which in turn is connected with the positions of the stationary points of the stream function ψ. Detailed calculations are given of the shape of the flux surfaces and of the shape of the magnetic well (the variation of ∫dℓ/B across it) for several examples of helical fields. These include the Furth-Rosenbluth configuration and a new configuration which provides a mean magnetic well without the necessity for a central conductor. A survey is also made of the magnetic well properties of these two classes of helical field in terms of two simple criteria: (1) the ratio Q of the field strength on the axis and on the separatrix (which provides an estimate of the overall well depth); and (2) the value of V'' on the magnetic axis (which provides a measure of the ''curvature'' of the well). This latter quantity is calculated analytically by using a general expression for the value of V'' on an arbitrary magnetic axis; It is pointed out that Q alone does not provide a realistic indication of the well shape.

  17. Progress in quantum well solar cells

    International Nuclear Information System (INIS)

    A quantum well solar cell is a special multiple-band gap device with intermediate properties between heterojunction cells (sum of the currents generated in the different materials but voltage controlled by the lowest of the two band gaps) and tandem cells (sum of the voltages but current determined by the worst of the two sub-cells). Strain-balanced GaAsP/InGaAs multi-quantum wells move the absorption edge of GaAs solar cells closer to the optimum value for single junction cells with no need for any partially relaxed buffer layer to accommodate lattice mismatch between the absorbing layers and the substrate. Covering a large spectral range in a single-junction cell has the benefit that the cell remains close to optimal efficiency in the varying spectral conditions of a typical terrestrial concentrator. Though monolithic multi-junction cells have significantly higher efficiency, the series-current constraint means that some of this advantage is lost as the illuminating spectra and the cell temperature change from the values at which the tandem was optimised. The good material quality which can be achieved with these structures makes the cell dark current at the typical operating conditions expected under moderate sunlight concentration (∼200x), increasingly dominated by radiative processes the deeper the quantum wells. We will report on high concentration measurements of strain-balanced quantum well solar cells with and without Bragg-stack reflectors and discuss the 'additivity' between the short-circuit current and the dark-current. We discuss a 50 shallow well cell with measured AM1.5d efficiency of (26 ± 1)% at around 200x concentration. This is approximately 2% higher than a comparable p-n cell with comparable material quality. The good material quality is also responsible for another effect previously observed in single quantum wells becoming measurable in structures with 5 and 10 wells, that is the suppression of carrier recombination in quantum wells with

    2007-01-01

    The Entiat 4-mile Wells (Entiat 4-mile) project is located in the Entiat subbasin and will benefit Upper Columbia steelhead, spring Chinook and bull trout. The goal of this project is to prevent juvenile fish from being diverted into an out-of-stream irrigation system and to eliminate impacts due to the annual maintenance of an instream pushup dam. The objectives include eliminating a surface irrigation diversion and replacing it with two wells, which will provide Bonneville Power Administration (BPA) and the Bureau of Reclamation (Reclamation) with a Federal Columbia River Power System (FCRPS) BiOp metric credit of one. Wells were chosen over a new fish screen based on biological benefits and costs. Long-term biological benefits are provided by completely eliminating the surface diversion and the potential for fish entrainment in a fish screen. Construction costs for a new fish screen were estimated at $150,000, which does not include other costs associated with implementing and maintaining a fish screening project. Construction costs for a well were estimated at $20,000 each. The diversion consisted of a pushup dam that diverted water into an off-channel pond. Water was then pumped into a pressurized system for irrigation. There are 3 different irrigators who used water from this surface diversion, and each has multiple water right claims totaling approximately 5 cfs. Current use was estimated at 300 gallons per minute (approximately 0.641 cfs). Some irrigated acreage was taken out of orchard production less than 5 years ago. Therefore, approximately 6.8 acre-feet will be put into the State of Washington Trust Water Right program. No water will be set aside for conservation savings. The construction of the two irrigation wells for three landowners was completed in September 2006. The Lower Well (Tippen/Wick) will produce up to 175 gpm while the Upper Well (Griffith) will produce up to 275 gpm during the irrigation season. The eight inch diameter wells were

    2015-09-01

    Refrigeration of a solid-state system with light has potential applications for cooling small-scale electronics and photonics. We show theoretically that two coupled semiconductor quantum wells are efficient cooling media for optical refrigeration because they support long-lived indirect electron-hole pairs. Thermal excitation of these pairs to distinct higher-energy states with faster radiative recombination allows an efficient escape channel to remove thermal energy from the system. This allows reaching much higher cooling efficiencies than with single quantum wells. From band-diagram calculations along with an experimentally realistic level scheme we calculate the cooling efficiency and cooling yield of different devices with coupled quantum wells embedded in a suspended nanomembrane. The dimension and composition of the quantum wells allow optimizing either of these quantities, which cannot, however, be maximized simultaneously. Quantum-well structures with electrical control allow tunability of carrier lifetimes and energy levels so that the cooling efficiency can be optimized over time as the thermal population decreases due to the cooling.

  20. Productivity and Injectivity of Horizontal Wells

    International Nuclear Information System (INIS)

    The work on modeling hydraulically fractured horizontal wells has moved forward. A literature review on the subject was done and some of the existing models have been coded and applied to example problems for evaluation purposes. Previous work on the elects of heterogeneities on the performance of horizontal wells was continued by conducting a sensitivity study on various parameters that were kept constant in the earlier study. For example, we have studied the elect of gas cap and aquifer size, well location, fluid viscosity, etc. The experimental work on using horizontal wells as injectors and producers in a gas injection gravity drainage process continued. New and repeat experiments were conducted. Work on streamline grids was advanced by considering example problems with highly distorted grids which cannot be directly used for flow simulation. Grid smoothing and domain mapping techniques were investigated to handle such situations. A technique was developed for the computation o f well index with consideration to wellbore pressure drop. A recently developed reservoir/wellbore coupling model was used for this purpose

  1. Solitons and vortices in nonlinear potential wells

    Dror, Nir

    2015-01-01

    We consider self-trapping of topological modes governed by the one- and two-dimensional (1D and 2D) nonlinear-Schrodinger/Gross-Pitaevskii equation with effective single- and double-well (DW) nonlinear potentials induced by spatial modulation of the local strength of the self-defocusing nonlinearity. This setting, which may be implemented in optics and Bose-Einstein condensates, aims to extend previous studies, which dealt with single-well nonlinear potentials. In the 1D setting, we find several types of symmetric, asymmetric and antisymmetric states, focusing on scenarios of the spontaneous symmetry breaking. The single-well model is extended by including rocking motion of the well, which gives rise to Rabi oscillations between the fundamental and dipole modes. Analysis of the 2D single-well setting gives rise to stable modes in the form of ordinary dipoles, vortex-antivortex dipoles (VADs), and vortex triangles (VTs), which may be considered as produced by spontaneous breaking of the axial symmetry. The con...

    Karasaki, K.

    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.

  3. ADVANCED TECHNOLOGIES FOR STRIPPER GAS WELL ENHANCEMENT

    International Nuclear Information System (INIS)

    As part of Task 1 in Advanced Technologies for Stripper Gas Well Enhancement, Schlumberger-Holditch Reservoir Technologies (H-RT) has joined with two Appalachian Basin producers, Great Lakes Energy Partners, LLC, and Belden and Blake Corporation to develop methodologies for identification and enhancement of stripper wells with economic upside potential. These industry partners have provided us with data for more than 700 wells in northwestern Pennsylvania. Phase 1 goals of this project are to develop and validate methodologies that can quickly and cost-effectively identify wells with enhancement potential. We have continued to enhance and streamline our software, and we are testing the final stages of our new Microsoft(trademark) Access/Excel based software. We are continuing to process the information and are identifying potential candidate wells that can be used in Phase 2 to validate the new methodologies. In addition, preparation of the final technical report is underway. During this quarter, we have presented our project and discussed the software to numerous Petroleum Technology Transfer Council (PTTC) workshops located in various regions of the United States

  4. On the Importance of Well-Being

    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....... This charge can be found in the recent work of both Joseph Raz and Thomas Scanlon. According to the latter the concept of well-being plays an unimportant role in an agent’s deliberation. As I will show, to claim this much is to undermine our initial claim; and to do that is to undermine some of the most...... 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...

  8. Design considerations for heated wells in gloveboxes

    International Nuclear Information System (INIS)

    Heated wells in gloveboxes have been used for many years by the Argonne National Laboratory Chemical Technology Division for nuclear-technology, waste-management, chemical-technology, and analytical-chemistry research. These wells allow experiments to be isolated from the main working volume of the glovebox. In addition, wells, when sealed, allow experiments to be conducted under pressurized or vacuum conditions. Until recently, typical maximum operational temperatures were about 500 C. However, more recent research is requiring operational temperatures approaching 900 C. These new requirements pose interesting design challenges that must be resolved. Some problem areas include temperature effects on material properties, maintaining a seal, cooling selected areas, and minimizing stresses. This paper discusses issues related to these design challenges and the ways in which these issues have been resolved

    1998-12-01

    Full Text Available Main objective of horizontal driling is to place a drain-hole for a long distance within the pay zone to enhance productivity or injectivity. In drilling horizontal wells, more serious problems appear than in drilling vertical wells. These problems are: poor hole cleaning, excessive torque and drag, hole filling, pipe stucking, wellbore instability, loss of circulation, formation damage, poor cement job, and difficulties at logging jobs. From that reason, successful drilling and production of horizontal well depends largely on the fluid used during drilling and completion phases. Several new fluids, that fulfill some or all of required properties (hole cleaning, cutting suspension, good lubrication, and relative low formation damage, are presented in this paper.

  11. Formation evaluation of a horizontal well

    International Nuclear Information System (INIS)

    In Upper Zakum Field, the interest in horizontal drilling has continued. A second horizontal well was drilled during the second half of 1989. This necessitated running logging tools for well control and to evaluate the reservoir characteristics. The logging tool selected for this well is that of Sperry-Sun. Tools configuration and tolerance were found to fulfil SADCO's requirements and specifications. This paper reports on the services produced which included Measurement While Drilling (MWD) directional services and RLL (Recorded Lithology Logging). The RLL services cover Dual Gamma Ray (DGR), Electromagnetic Wave Resistivity (EWR) and Compensated Neutron Porosity (CN porosity). All the RLL tools were an integrated part of the Bottom Hole Drilling Assembly. Data acquired while surveying was recorded in a recording sub down-hole and retrieved when the tools were up at the surface. A PC assisted quick look interpretation was carried out using Archie's equation in shale free limestone to calculate: Effective porosity, Water Saturation and, Bulk water volume

    An indium phosphide photovoltaic cell is provided where one or more quantum wells are introduced between the conventional p-conductivity and n-conductivity indium phosphide layer. The approach allows the cell to convert the light over a wider range of wavelengths than a conventional single junction cell and in particular convert efficiently transparency losses of the indium phosphide conventional cell. The approach hence may be used to increase the cell current output. A method of fabrication of photovoltaic devices is provided where ternary InAsP and InGaAs alloys are used as well material in the quantum well region and results in an increase of the cell current output.

    Baltenkov, A S

    2016-01-01

    The effects of quantum confinement on the momentum distribution of electrons confined within a cylindrical potential well have been analyzed. The motivation is to understand specific features of the momentum distribution of electrons when the electron behavior is completely controlled by the parameters of a non-isotropic potential cavity. It is shown that studying the solutions of the wave equation for an electron confined in a cylindrical potential well offers the possibility to analyze the confinement behavior of an electron executing one- or two-dimensional motion in the three-dimensional space within the framework of the same mathematical model. Some low-lying electronic states with different symmetries have been considered and the corresponding wave functions have been calculated; the behavior of their nodes and their peak positions with respect to the parameters of the cylindrical well has been analyzed. Additionally, the momentum distributions of electrons in these states have been calculated. The limi...

  16. Investigation of well redevelopment techniques for the MWD Well Field, Savannah River Site, South Carolina

    International Nuclear Information System (INIS)

    Clemson University, in cooperation with the Savannah River Site (SRS) is investigating well treatment techniques at the Mixed Waste Disposal (MWD) Well Field at SRS. This well field consists of fifteen wells screened in three aquifers with a downward trending head gradient. Based on aquifer performance tests of the MWD wells, it has been determined that many of the wells exhibit low well efficiencies and high skin factors, indicative of damaged wells. Bacterial investigations show that the biological activity in these wells is low, probably due to a high pH environment. Evaluation of the Calcite Saturation Index for each well indicates that nearly all of the MWD wells have the potential for precipitating calcite and calcite deposits have been observed on downhole equipment. The calcite deposits may occur due to the dissolution of the grout mixtures by waters infiltrating down the well annulus driven by the downward head gradient with subsequent precipitation of calcite in the higher pH sand pack. Well rehabilitation techniques currently under investigation include acidification, hydraulic fracturing and traditional physical methods. In addition to treating the wells at MWD, the authors plan to perform aquifer performance tests and evaluate post-treatment skin factors. Further research into the long term effects of well treatment will be conducted, focusing on long term chemical changes brought about by the treatments

  17. Well screening for matrix stimulation treatments

    International Nuclear Information System (INIS)

    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

    2015-01-01

    Active stabilization in systems with zero or negative stiffness is an essential element of a wide variety of biological processes. We study a prototypical example of this phenomenon at a micro-scale and show how active rigidity, interpreted as a formation of a pseudo-well in the effective energy landscape, can be generated in an overdamped ratchet-type stochastic system. We link the transition from negative to positive rigidity with correlations in the noise and show that subtle differences in out-of-equilibrium driving may compromise the emergence of a pseudo-well.

  19. Well-Founded Belief and Perceptual Justification

    DEFF Research Database (Denmark)

    Broncano-Berrocal, Fernando

    2016-01-01

    According to Alan Millar, justified beliefs are well-founded beliefs. Millar cashes out the notion of well-foundedness in terms of having an adequate reason to believe something and believing it for that reason. To make his account of justified belief compatible with perceptual justification he...... appeals to the notion of recognitional ability. It is argued that, due to the fact that Millar's is a knowledge-first view, his appeal to recognitional abilities fails to offer an explanatory account of familiar cases in the literature and, as a consequence, of the notion of perceptual justification....

    The aim of this research is to describe and characterize the reservoir sections by well log data. Well logs are used to examine the porosity, water saturation and true resistivity properties of the reservoir. Throughout the project, the data is processed using geostatistical tests that are frequency, histograms, auto-correlation, cross-correlations, linear and multiple regression analysis to find the relations between the variables. Statistical analyses are performed using SPSS software. From the output of the software, the data of the reservoir section would be improved resulting in a higher efficiency in the usage of the data.

  5. Spring mires fed by hot artesian water in Kruger National Park, South Africa

    Directory of Open Access Journals (Sweden)

    A.P. Grootjans

    2010-12-01

    Full Text Available This article describes two spring mire complexes in the Kruger National Park (South Africa that are fed by thermal water with a temperature of 37–42°C. The mires are small (1–20 m in diameter. The peat thickness is 1–2.5 m, of which 1–1.5 m is elevated above the surroundings. Some of the domes have dried out severely and show signs of erosion due to water flow and trampling by large animals. The mires lie in an almost straight line, supporting the hypothesis that the water originates from deep aquifers which discharge at geological faults. The long-term existence of these spring mire complexes may not be threatened because young stages of mire formation are present, but research to elucidate the timescales of peat development is needed to make a valid prognosis.

    1976-01-01

    The series of computer programs described in this report were designed specifically to model the ground-water regime in sufficient detail to determine the effects of the imposition of various types of stress upon the system, and to display the results in a convenient manner during calibration and when presenting projected data. SUPERMOCK simulates the ground-water system and DATE and HYDROG aid in the display of computed data. During calibration, DATE is especially useful because it has the optional feature of comparing computed data with observed data. Although the programs can be run independently, experience dictates that for best results the three should be run as steps in the same job. English units of inches, feet, and days are used in each of the programs. The units for any parameters not given in the text are clearly specified in the instructions for input to the individual programs. (Woodard-USGS)

  7. Well-Being on Planet Earth

    Directory of Open Access Journals (Sweden)

    2009-12-01

    Full Text Available The Gallup World Poll allows a look at how humanity is flourishing, based on the answers of survey respondents sampled from across the globe. Several conclusions are clear. First, how people are doing depends enormously on the society in which they live, and nations vary from doing very well to extremely poorly. In terms of subjective well-being, nations vary greatly, in both judgments of overall life and in positive and negative emotions. The best predictors of global life judgments were income and ownership of modern conveniences, whereas the best predictors of emotions were social factors such as the control of corruption and being able to count on others, and personal factors such as learning new things and being able to control one’s day. Thus, the answer to the question of whether money makes people happy must be qualified by the measure of well-being that is being used. It is proposed that systematic measures of well-being across and within nations would allow individuals, leaders, and policy makers to make better decisions.

  16. Spectroscopy of GaAs quantum wells

    Energy Technology Data Exchange (ETDEWEB)

    West, L.C.

    1985-07-01

    A new type of optical dipole transition in GaAs quantum wells has been observed. The dipole occurs between two envelope states of the conduction band electron wavefunction, and is called a quantum well envelope state transition (QWEST). The QWEST is observed by infrared absorption in three different samples with quantum well thicknesses 65, 82, and 92 A and resonant energies of 152, 121, and 108 MeV, respectively. The oscillator strength is found to have values of over 12, in good agreement with prediction. The linewidths are seen as narrow as 10 MeV at room temperature and 7 MeV at low temperature, thus proving a narrow line resonance can indeed occur between transitions of free electrons. Techniques for the proper growth of these quantum well samples to enable observation of the QWEST have also been found using (AlGa)As compounds. This QWEST is considered to be an ideal material for an all optical digital computer. The QWEST can be made frequency matched to the inexpensive Carbon Dioxide laser with an infrared wavelength of 10 microns. The nonlinearity and fast relaxation time of the QWEST indicate a logic element with a subpicosecond switch time can be built in the near future, with a power level which will eventually be limited only by the noise from a lack of quanta to above approximately 10 microwatts. 64 refs., 35 figs., 6 tabs.

    1983-01-01

    An improvement for an indirect method for studying wells equipped with submersible pumping installations proposed by the authors is presented. Acoustical instruments are used to measure the level of liquid in the well with the indirect methods for investigating wells. It is proposed that the stratum pressures Ppl be determined using pressure measurements at the level of suspension of the pump by a submersible pressure gauge, Pn from the formula Ppl = Pn - 10exp-5gammavlv + 10exp5gamman times cosalpha(1 - 10), where lb = n(1(gammazh - gamman)/(gammav - gamman) + deltah), 1 is the distance from the bottom hole to the intake of the pump, gamman, gammav and gammazh are the density of the stratum oil, water and liquid, respectively, n is the flooded state, deltah is the difference between the dynamic and static levels and alpha is the curvature angle of the well shaft. The coefficient of productivity should be determined from Muskat's refined relationship of eta = 2,000 times F(t2(HO - H1) - tl(H1 - H2))/(gammaplzhtlt2(HO - H2)), where F is the surface area of the stream cross section, H0, H1 and H2 are the levels of the liquid at the start of the study and after times of t1 and t2 and gammaplzh is the density of the stratum liquid. The level of the liquid in the casing annulus should be traced with a constant wellhead pressure.

  14. Warren Hunt to test granite well

    International Nuclear Information System (INIS)

    Various theories which purport to explain the existence of the Alberta oil sands, were discussed briefly. One theory, held among others by Warren Hunt, speculates that oil is formed deep in the Precambrian basement and not in the higher sedimentary rock. According to this theory, methane in the crust is the abiogenic product that results from hydrogen reacting with silicon carbide in the lower mantle. As it rises through the fractures, it encounters the microbiota, and hydrogen is stripped away making larger molecules until only bitumen remains. Hunt and other adherents of this theory believe that hydrocarbon reservoirs are replenished as oil is produced, hence there is no end to the world's oil supply. This theory is about to be tested by retesting a granite well near Fort McMurray, which was suspended in September 1994, when funding dried up. Kaleeda Enterprises, owners of the well, believe that the well bottom is currently in a granite pool, and oil will be found by deepening the well to 2,150 metres from the current 1,650 metres. While this is not universally accepted, if true, the abiogenic theory would go a long way towards explaining the origin of the oil sands

  17. Erbium in silicon-germanium quantum wells

    International Nuclear Information System (INIS)

    Strained Si1-xGex/Si quantum wells have been doped with erbium by implantation. A comparison is made with strained Si1-xGex/Si quantum wells and relaxed Si1-xGex, with x between 10% and 25%, doped with erbium during MBE growth. The erbium concentration was between 1x1018 and 5x1018 cm-3 throughout the active regions. Transmission electron microscopy, X-ray diffraction, and photoluminescence studies indicate that good regrowth can been achieved after full amorphisation by implantation of the strained quantum wells. The erbium luminescence is more intense in the Si1-xGex/Si layers, but erbium-implanted samples containing Si1-xGex exhibit defect luminescence in the region of 0.9-1.0 eV. These defects are also present when Si1-xGex/Si quantum wells are implanted with an amorphising dose of silicon, and then regrown. They are attributed to small germanium-rich platelets, rather than to erbium-related defects. Electroluminescence is presented from a forward biased erbium-implanted Si0.87Ge0.13/Si structure at a drive current density of only 1.8 mA/cm2. (Copyright (c) 1998 Elsevier Science B.V., Amsterdam.

    Full Text Available Abnormal fluoride levels in drinking water have been associated with adverse health effects. To determine the fluoride content of well waters in Enugu, southeastern Nigeria, water samples from 50 artisan wells chosen by multistage sampling procedure from the 5 zones of Enugu municipality were analyzed in duplicates for their fluoride content. The zonal mean values were 0.60, 0.70, 0.62, 0.62, and 0.63 mg/L for Abakpa Nike, Achara Layout, Obiagu/ Ogui, Trans Ekulu and Uwani, respectively (p<0.05. The mean value for the whole city was 0.63 mg/L. Although, the mean level of fluoride recorded in this study is currently within safe limits (1.5 mg/L, WHO 2011, it is important to monitor continuously the fluoride content of well waters in the municipality in view of the increasing industrial activities going on in the city and heavy reliance on well water for domestic purposes and the widespread use of consumer products containing fluoride.

  19. Consortium for Petroleum & Natural Gas Stripper Wells

    2011-12-01

    The United States has more oil and gas wells than any other country. As of December 31, 2004, there were more than half a million producing oil wells in the United States. That is more than three times the combined total for the next three leaders: China, Canada, and Russia. The Stripper Well Consortium (SWC) is a partnership that includes domestic oil and gas producers, service and supply companies, trade associations, academia, the Department of Energy’s Strategic Center for Natural Gas and Oil (SCNGO) at the National Energy Technology Laboratory (NETL), and the New York State Energy Research and Development Authority (NYSERDA). The Consortium was established in 2000. This report serves as a final technical report for the SWC activities conducted over the May 1, 2004 to December 1, 2011 timeframe. During this timeframe, the SWC worked with 173 members in 29 states and three international countries, to focus on the development of new technologies to benefit the U.S. stripper well industry. SWC worked with NETL to develop a nationwide request-for-proposal (RFP) process to solicit proposals from the U.S. stripper well industry to develop and/or deploy new technologies that would assist small producers in improving the production performance of their stripper well operations. SWC conducted eight rounds of funding. A total of 132 proposals were received. The proposals were compiled and distributed to an industry-driven SWC executive council and program sponsors for review. Applicants were required to make a formal technical presentation to the SWC membership, executive council, and program sponsors. After reviewing the proposals and listening to the presentations, the executive council made their funding recommendations to program sponsors. A total of 64 projects were selected for funding, of which 59 were fully completed. Penn State then worked with grant awardees to issue a subcontract for their approved work. SWC organized and hosted a total of 14 meetings

  20. Flowback patterns of fractured shale gas wells

    Directory of Open Access Journals (Sweden)

    Naizhen Liu

    2015-03-01

    Full Text Available Shale gas reservoirs generally need to be fractured massively to reach the industrial production, however, the flowback ratio of fractured shale gas wells is low. In view of this issue, the effects of natural fracture spacing, fracture conductivity, fracturing scale, pressure coefficient and shut-in time on the flowback ratio were examined by means of numerical simulation and experiments jointly, and the causes of flowback difficulty of shale gas wells were analyzed. The results show that the flowback ratio increases with the increase of natural fracture spacing, fracture conductivity and pressure coefficient and decreases with the increase of fracturing scale and shut-in time. From the perspective of microscopic mechanism, when water enters micro-cracks of the matrix through the capillary self-absorbing effect, the original hydrogen bonds between the particles are replaced by the hydroxyl group, namely, hydration effect, giving rise to the growth of new micro-cracks and propagation of main fractures, and complex fracture networks, so a large proportion of water cannot flow back, resulting in a low flowback ratio. For shale gas well fracturing generally has small fracture space, low fracture conductivity and big fracturing volume, a large proportion of the injected water will be held in the very complex fracture network with a big specific area, and unable to flow back. It is concluded that the flowback ratio of fractured shale gas wells is affected by several factors, so it is not necessary to seek high flowback ratio deliberately, and shale gas wells with low flowback ratio, instead, usually have high production.

    A water-based carbon screen-printing ink formulation, containing the redox mediator cobalt phthalocyanine (CoPC) and the enzyme glucose oxidase (GOx), was investigated for its suitability to fabricate glucose microbiosensors in a 96-well microplate format: (1) the biosensor ink was dip-coated onto a platinum (Pt) wire electrode, leading to satisfactory amperometric performance; (2) the ink was deposited onto the surface of a series of Pt microelectrodes (10-500 μm diameter) fabricated on a silicon substrate using MEMS (microelectromechanical systems) microfabrication techniques: capillary deposition proved to be successful; a Pt microdisc electrode of ≥100 μm was required for optimum biosensor performance; (3) MEMS processing was used to fabricate suitably sized metal (Pt) tracks and pads onto a silicon 96 well format base chip, and the glucose biosensor ink was screen-printed onto these pads to create glucose microbiosensors. When formed into microwells, using a 340 μl volume of buffer, the microbiosensors produced steady-state amperometric responses which showed linearity up to 5 mM glucose (CV=6% for n=5 biosensors). When coated, using an optimised protocol, with collagen in order to aid cell adhesion, the biosensors continued to show satisfactory performance in culture medium (linear range to 2 mM, dynamic range to 7 mM, CV=5.7% for n=4 biosensors). Finally, the operation of these collagen-coated microbiosensors, in 5-well 96-well format microwells, was tested using a 5-channel multipotentiostat. A relationship between amperometric response due to glucose, and cell number in the microwells, was observed. These results indicate that microphotolithography and screen-printing techniques can be combined successfully to produce microbiosensors capable of monitoring glucose metabolism in 96 well format cell cultures. The potential application areas for these microbiosensors are discussed. PMID:23265827

Because of a cooperative agreement between the City and the US Department of Energy to design and construct the proposed well, compliance to the National Environmental Policy Act (NEPA) is required. Therefore, this Environmental Assessment (EA) represents the analysis of the proposed project required under NEPA. The intent of this EA is to: (1) briefly describe historical uses of the Boise Geothermal Aquifer; (2) discuss the underlying reason for the proposed action; (3) describe alternatives considered, including the No Action Alternative and the Preferred Alternative; and (4) present potential environmental impacts of the proposed action and the analysis of those impacts as they apply to the respective alternatives.

  6. Radon in private drinking water wells

    International Nuclear Information System (INIS)

    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)

    Introduction: Beginning as a grassroots initiative, a community hospital employing 2800 celebrates the stress-transforming benefits of HeartMath for its employees and community. Initially introduced to address the deleterious effects of personal stress experienced by the high healthcare claimants of the organization, HeartMath was eventually introduced to every stratification of the organization's population health management. The ensuing depth and breadth of HeartMath's presence in the organization is a consequence of a deliberate effort to integrate the program at every possible and sensible touch point of the organization and, ultimately, patient care. Today, 5 years later, the success of HeartMath at Indiana University (IU) Health Bloomington continues to be a tribute to the grassroots movement of an established worksite wellness program. Methods: HeartMath was initiated as an intervention for transforming the stress of a workforce's highest healthcare claimants: those with the complexities of co-morbidities as well as challenging psychosocial and economic realities. This segment of a workforce is invariably the greatest strain to any organization's health plan. As importantly, on an individual level and subsequent to their health status, the respective employees can experience tremendous personal strain in several dimensions of their lives. Further compounding their marginal and worsening physical health, the inherent challenges of the current medical system to integrate and advocate for their care requires that stress be addressed and skills developed for a positive, long-term, and sustainable outcome. From this small but powerful vantage point, IU Health Bloomington's platinum worksite wellness program (a distinction of the Wellness Council of America) extended HeartMath to every population health management stratification within the organization. This specific program migration happened initially by way of departments and units that expressed, in an

  10. Assessment of radiation safety in well logging

    International Nuclear Information System (INIS)

    Radiation safety assessments required by current regulations are a means to verify compliance with the requirements. Different methods have been used for this purpose. In the paper the results of applying the method of risk matrices, applied for the first time in the practice of well logging are exposed. For each initiating event frequency of occurrence, the severity of its consequences and the probability of failure of the barriers identified were evaluated. Starting from these assumptions, the risk associated is determined for each of the identified accident sequences, using for this the SEVRRA code 'Risk Assessment System', originally designed for use in radiotherapy. As an result sequences increased risk associated with the practice of well logging were identified, which is the starting point for the further implementation of a coherent program of dose optimization in practice.

  11. Photonic Crystal Slab Quantum Well Infrared Photodetector

    International Nuclear Information System (INIS)

    Full text: Photonic crystals (PCs) exhibit fascinating properties for the control of light. Two-dimensional (2D) PCs are the most important class, as they are compatible with standard semiconductor processing. For confinement of photons in the out-of-plane direction a photonic crystal slab (PCS) is often used. By fabricating a PCS from a photosensitive material the resonant modes of the PCS can be directly measured in the photocurrent spectrum of the device. For detection of light in the mid-infrared region (MIR) we used a quantum well infrared photodetector (QWIP). At the resonance frequencies of the PCS the lifetime of the photons is increased, which increases the photon absorption. Therefore, a lower doping concentration in the quantum wells of the active zone can be used. With a lower doping concentration the thermal noise is reduced and maximum operation temperature can be increased. (author)

    We study accelerator modes of a particle, confined in an one-dimensional infinite square well potential, subjected to a time-periodic pulsed field. Dynamics of such a particle can be described by one generalization of the kicked rotor. In comparison with the kicked rotor, this generalization is shown to have a much larger parametric space for existence of the modes. Using this freedom we provide evidence that accelerator mode assisted anomalous transport is greatly enhanced when low order res...

  17. Electronic quantum confinement in cylindrical potential well

    Baltenkov, Arkadiy S.; Msezane, Alfred Z.

    2016-04-01

    The effects of quantum confinement on the momentum distribution of electrons confined within a cylindrical potential well have been analyzed. The motivation is to understand specific features of the momentum distribution of electrons when the electron behavior is completely controlled by the parameters of a non-isotropic potential cavity. It is shown that studying the solutions of the wave equation for an electron confined in a cylindrical potential well offers the possibility to analyze the confinement behavior of an electron executing one- or two-dimensional motion in the three-dimensional space within the framework of the same mathematical model. Some low-lying electronic states with different symmetries have been considered and the corresponding wave functions have been calculated; the behavior of their nodes and their peak positions with respect to the parameters of the cylindrical well has been analyzed. Additionally, the momentum distributions of electrons in these states have been calculated. The limiting cases of the ratio of the cylinder length H and its radius R0 have been considered; when the cylinder length H significantly exceeds its radius R0 and when the cylinder radius is much greater than its length. The cylindrical quantum confinement effects on the momentum distribution of electrons in these potential wells have been analyzed. The possible application of the results obtained here for the description of the general features in the behavior of electrons in nanowires with metallic type of conductivity (or nanotubes) and ultrathin epitaxial films (or graphene sheets) are discussed. Possible experiments are suggested where the quantum confinement can be manifested.

  18. Hydrodynamics plasmons on wide parabolic quantum wells

    International Nuclear Information System (INIS)

    We report progress towards a simple, reliable theory of plasmons on mesoscopic structures of arbitrary geometry. Fully microscopic many-body quantum theories are usually too cumbersome, and quantum hydrodynamics is an attractive option. Simple hydrodynamics has been widely used, e.g. for thin metal films. In most such calculations, the equilibrium electron gas has been assumed uniform up to a sharp boundary. In describing the plasmon motions, hard-wall boundary conditions at the electron gas edge have usually been added in an ad hoc fashion. Experiment and microscopic theoretical work have shown, however, that the details of the nonuniform equilibrium electron density near the edge of the sample are crucial in determining the dispersion of surface plasmons. Once this inhomogeneity of the electron gas is included, simple hydrodynamic models fail, and one requires a new form of hydrodynamics. Here we report tests of the new hydrodynamics using the parabolic quantum well, a system well-understood both experimentally and from microscopic theory and for which the usual hydrodynamics fails to give the known frequency of the Kohn or sloshing plasmon mode. GaAs/GaAlAs parabolic quantum wells have been grown by molecular beam epitaxy with the Al content varying during growth in such a way that conduction electrons feel an effective parabolic potential V(z)= (const)z2 where 'z' is the space coordinate in the layer growth direction. By remote doping, a highly mobile electron gas layer is formed which partially fills the parabolic well. Microscopic theory shows that this electron gas, when IR-irradiated at finite surface-parallel wavenumber 'q' via a grating coupler, exhibits absorption peaks at 2D plasmons, Kohn-mode and bulk standing plasmon frequencies. The new hydrodynamics yield all these modes with use of one natural boundary conditions

    Full Text Available Introduction. For the difference from poorly differentiated, well differentiated endocrine carcinomas of the pancreas are the tumours in whom with aggressive surgery and chemotherapy fair results can be achieved. Objective. The aim of the study was to point out the importance of such treatment. Methods. Over a 6-year period eight patients (seven female and one male of average age 51 years (ranging from 23 to 71 years were operated on for well differentiated endocrine carcinoma: six of the head and two of the tail of the pancreas. There were two functional and six nonfunctional tumours. Pain in the upper part of the abdomen in seven, mild loss in weight in two, strong heartburn in two, obstructive jaundice in three, diarrhoea in one, sudden massive bleeding from gastric varicosities due to prehepatic portal hypertension caused by pancreatic head tumour in one, and bruise in one patient were registered preoperatively. US and CT in all, angiography in one, octreoscan in two and PET scan in one patient were performed. Whipple’s procedure was performed in six and distal pancreatectomy in two patients, as well as systemic lymphadenectomy in all and excision of liver secondary tumours in two patients. In the patient with massive gastric bleeding a total gastrectomy was performed first, followed by Whipple’s procedure a month later. Results. R0 resection was achieved in all patients. Lymph nodes metastases were found in six patients. Six patients were given chemotherapy. One patient died 3 years after surgery, seven are still alive, on average 2.5 years. A local recurrence after distal pancreatectomy that occurred 5 years after surgery was successfully reresected and the patient is on peptide-receptor radiotherapy. In other six patients there were no local recurence or distant metastases. Conclusion. With aggressive surgery and chemotherapy fair results can be achieved in well differentiated endocrine carcinomas of the pancreas.

    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.

  9. In-situ bioremediation via horizontal wells

    International Nuclear Information System (INIS)

    This project is designed to demonstrate in situ bioremediation of groundwater and sediment contaminated with chlorinated solvents. Indigenous microorganisms were stimulated to degrade TCE, PCE and their daughter products in situ by addition of nutrients to the contaminated zone. In situ biodegradation is a highly attractive technology for remediation because contaminants are destroyed, not simply moved to another location or immobilized, thus decreasing costs, risks, and time, while increasing efficiency and public and regulatory acceptability. Bioremediation has been found to be among the least costly technologies in applications where it will work (Radian 1989). Subsurface soils and water adjacent to an abandoned process sewer line at the SRS have been found to have elevated levels of TCE (Marine and Bledsoe 1984). This area of subsurface and groundwater contamination is the focus of a current integrated demonstration of new remediation technologies utilizing horizontal wells. Bioremediation has the potential to enhance the performance of in situ air stripping as well as offering stand-alone remediation of this and other contaminated sites (Looney et al. 1991). Horizontal wells could also be used to enhance the recovery of groundwater contaminants for bioreactor conversions from deep or inaccessible areas (e.g., under buildings) and to enhance the distribution of nutrient or microbe additions in an in situ bioremediation

    From the introduction: The Remote Operations in Oklahoma Intended for Education (ROOKIE) project is a remote field laboratory constructed as a part of this research project. ROOKIE was initiated to provide data in research on production optimization of low productivity gas wells. In addition to this, ROOKIE is used as a teaching tool. Much of the remote operations technology used in the ROOKIE project has been used by the industry for several decades. The first use of remote data acquisition in Oklahoma was in 1989, as described by Luppens [7]. Even though this, for the most part, is old technology, the ROOKIE project is the first remote operations project set up with research and teaching as the main focus. This chapter will discuss the process of establishing the remote field laboratory and the data storage facilities. Results from the project will also be discussed. All testing, instrumentation installation, and modifications to the wells discussed in this chapter was performed by the author. The communication system between the well and NTNU, and the storage database was installed and configured by the author.(Author)

  11. Hard-core square-well fermions

    International Nuclear Information System (INIS)

    Based on the well-known low-density expansion for the ground-state energy per particle of a many-fermion system interacting pairwise via a central potential we develop a perturbation scheme in which the zero-order state is that of the purely-repulsive-spheres fluid. For the hard-core plus square-well pair-interaction case we have deduced, for two-species fermion matter, perturbation formulas up to sixth order in the attractive coupling parameter. We explicitly report results up to fourth order here. Pade-approximant analyses in the density are carried out in each order with the intent of providing the basis necessary for extensive equation-of-state calculations of various many-fermion systems. In particular, for zero order (the fermion hard-sphere fluid) we predict an uncertainty-principle divergence in the energy, and hence pressure, corresponding to the random close packing of spheres, at a density of about 0.5 times the recently obtained value for boson hard spheres and about 0.2 times the well-known empirical value for classical hard spheres

  12. Recompletion Report for Well UE-10j

    International Nuclear Information System (INIS)

    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

    2016-07-01

    We address an eigenvalue problem for the ultrarelativistic (Cauchy) operator (-Δ)1/2, whose action is restricted to functions that vanish beyond the interior of a unit sphere in three spatial dimensions. We provide high accuracy spectral data for lowest eigenvalues and eigenfunctions of this infinite spherical well problem. Our focus is on radial and orbital shapes of eigenfunctions. The spectrum consists of an ordered set of strictly positive eigenvalues which naturally splits into non-overlapping, orbitally labelled E(k,l) series. For each orbital label l = 0, 1, 2, …, the label k = 1, 2, … enumerates consecutive lth series eigenvalues. Each of them is 2l + 1-degenerate. The l = 0 eigenvalues series E(k,0) are identical with the set of even labeled eigenvalues for the d = 1 Cauchy well: E(k,0)(d = 3) = E2k(d = 1). Likewise, the eigenfunctions ψ(k,0)(d = 3) and ψ2k(d = 1) show affinity. We have identified the generic functional form of eigenfunctions of the spherical well which appear to be composed of a product of a solid harmonic and of a suitable purely radial function. The method to evaluate (approximately) the latter has been found to follow the universal pattern which effectively allows to skip all, sometimes involved, intermediate calculations (those were in usage, while computing the eigenvalues for l ≤ 3).

    This report summarizes the research conducted during Budget Period One on the project ''Improved Natural Gas Storage Well Remediation''. The project team consisted of Furness-Newburge, Inc., the technology developer; TechSavants, Inc., the technology validator; and Nicor Technologies, Inc., the technology user. The overall objectives for the project were: (1) To develop, fabricate and test prototype laboratory devices using sonication and underwater plasma to remove scale from natural gas storage well piping and perforations; (2) To modify the laboratory devices into units capable of being used downhole; (3) To test the capability of the downhole units to remove scale in an observation well at a natural gas storage field; (4) To modify (if necessary) and field harden the units and then test the units in two pressurized injection/withdrawal gas storage wells; and (5) To prepare the project's final report. This report covers activities addressing objectives 1-3. Prototype laboratory units were developed, fabricated, and tested. Laboratory testing of the sonication technology indicated that low-frequency sonication was more effective than high-frequency (ultrasonication) at removing scale and rust from pipe sections and tubing. Use of a finned horn instead of a smooth horn improves energy dispersal and increases the efficiency of removal. The chemical data confirmed that rust and scale were removed from the pipe. The sonication technology showed significant potential and technical maturity to warrant a field test. The underwater plasma technology showed a potential for more effective scale and rust removal than the sonication technology. Chemical data from these tests also confirmed the removal of rust and scale from pipe sections and tubing. Focusing of the underwater plasma's energy field through the design and fabrication of a parabolic shield will increase the technology's efficiency. Power delivered to the underwater plasma unit

    The long-term integrity of CO2 storage in geological system relies highly on local trapping mechanisms but also on the absence/control of any kind of outlets. Indeed numerous pathways (faults, wells, rock heterogeneities…) exist that can lead stored gas back to the surface. Thus, such leakage risks must be assessed and quantified if possible. In France, BRGM is inquired for evaluating safety criteria and developing a methodology for qualifying potential geological storage sites. This implies in particular to study the leakage scenario, here through a water-filled well as a worth scenario case. In order to determine the kinds of impacts leaking CO2 can have; knowing the velocity and flow rate of uprising CO2 is a necessity. That is why a better knowledge of CO2 in storage conditions and its behaviour with the environment is required. The following study aims at characterising the CO2 flowing into the well and then rising up in a water column over the vertical dimension. An analytical model was built that describes: - In a first step, the CO2 flow between the reservoir and the inside of the well, depending on quality and thickness of different seals, which determines the flow rate through the well. - In a second step, the CO2 uprising through an open and water filled well, however in steady state, which excludes a priori the characterisation of periodic or chaotic behaviours such as geyser formation. The objective is to give numerous orders of magnitude concerning CO2 thermodynamic properties while rising up: specific enthalpy, density, viscosity, velocity, flow, gas volume fraction and expansion, pressure and temperature gradient. Dissolution is partially taken into account, however without kinetic. The strength of this model is to compute analytically - easily and instantaneously - the 1-dimensional rising velocity of CO2 in a water column as a function of the CO2 density, interfacial tension and initial volume fraction. Characteristic speeds - the ones given by

    2014-01-01

    A new well test model is developed for the hydraulic fractured well in coalbed by considering the following aspects: methane desorption phenomena, finite conductivity vertical fractures, and asymmetry of the fracture about the well. A new parameter is introduced to describe the storage of the fracture, which is named as a combined fracture storage. Another new concept called the fracture asymmetry coefficient is used to define the asymmetry of the fracture about the well. Finite element method (FEM) is used to solve the new mathematical model. The well test type curves and pressure fields are obtained and analyzed. The effects of the combined fracture storage, desorption factor, fracture conductivity, and fracture asymmetry coefficient on the well test type curves are discussed in detail. In order to verify the new model, a set of field well test data is analyzed.

    In the past, infrared imaging has been used exclusively for military applications. In fact, it can also be useful in a wide range of scientific and commercial applications. However, its wide spread use was impeded by the scarcity of the imaging systems and its high cost. Recently, there is an emerging infrared technology based on quantum well intersubband transition in III-V compound semiconductors. With the new technology, these impedances can be eliminated and a new era of infrared imaging is in sight. This book is designed to give a systematic description on the underlying physics of the ne

    The study on the Fano resonances is carried out in the 2D systems and their contribution to the residual resistance is calculated. The quantum well, the states whereof interfere with the nanocenters, for example, with the delta-layer donor states or with the quantum points states, is considered as a model. It is shown, that the states, localized on the state centers, lead to the appearance of additional asymmetric peaks in the resistance dependence on the Fermi energy. It is also shown, that the finite radius nanocenters in the 2D electron layers may lead to origination of the Fano resonances in the scattering cross section

    The objective of this project was to develop a sonic well performance enhancement technology that focused on near wellbore formation damage. In order to successfully achieve this objective, a three-year project was defined. The entire project was broken into four tasks. The overall objective of all this was to foster a better understanding of the mechanisms involved in sonic energy interactions with fluid flow in porous media and adapt such knowledge for field applications. The fours tasks are: • Laboratory studies • Mathematical modeling • Sonic tool design and development • Field demonstration The project was designed to be completed in three years; however, due to budget cuts, support was only provided for the first year, and hence the full objective of the project could not be accomplished. This report summarizes what was accomplished with the support provided by the US Department of Energy. Experiments performed focused on determining the inception of cavitation, studying thermal dissipation under cavitation conditions, investigating sonic energy interactions with glass beads and oil, and studying the effects of sonication on crude oil properties. Our findings show that the voltage threshold for onset of cavitation is independent of transducer-hydrophone separation distance. In addition, thermal dissipation under cavitation conditions contributed to the mobilization of deposited paraffins and waxes. Our preliminary laboratory experiments suggest that waxes are mobilized when the fluid temperature approaches 40°C. Experiments were conducted that provided insights into the interactions between sonic wave and the fluid contained in the porous media. Most of these studies were carried out in a slim-tube apparatus. A numerical model was developed for simulating the effect of sonication in the nearwellbore region. The numerical model developed was validated using a number of standard testbed problems. However, actual application of the model for scale

  7. Squeezed potato orbits in a magnetic well

    International Nuclear Information System (INIS)

    It is shown that potato orbits in the near-axis region of a high beta tokamak are squeezed in a magnetic well. The squeezing factor is the same as that for the banana orbits derived in an earlier work [Phys. Plasmas 3, 2843 (1996)]. It depends on the energy of the particle. For high-energy particles, the size of the squeezed orbits is independent of their energy. This implies improved confinement for high-energy particles and for high beta tokamaks with advanced fuels

  11. Lifetime of a Natural Gas Storage Well Assessment of Well-Field Maintenance Cost

    International Nuclear Information System (INIS)

    Gaz de France has been operating underground gas storage wells since more than 50 years. These wells have been drilled with the current available technologies in oil and gas industry. These technologies had improved a lot in the last decades (slurry compositions, drilling and cementing techniques, etc.) and the lifetime of a well therefore has to be estimated with reference to the techniques in use at the date it was built. These uncertainties and the inaccurate data of the oldest wells (drilling logs and casings specifications) led GDF to investigate the wells lifetime. Two approaches are presented here: - assessing a theoretical lifetime of a well; - calculating the average lifetime of each well using essentially corrosion scenarios and kinetics. Combining the two different approaches, one can better assess well aging and remaining well lifetime in order to schedule the best action (work-over, abandonment) at the proper time. A better knowledge of well's lifetime enables good control of underground storage operational expenditures (OPEX). (author)

  13. Radiation incident in oil well logging

    International Nuclear Information System (INIS)

    On June 4th 1997 equipment failure and violation of approved procedures by a crew of workers initiated a series of events that resulted in the unnecessary exposure to neutron and gamma radiation, from a 666 GBq Am241Be source, of forty two workers from a well logging company in Venezuela. Due to the presence of dry mud or drilling fluids inside the logging tool, the nosepiece was screwed off the rest of the source holder; this piece was mistaken for the entire source holder thus leaving the source inside the tool. The tool was labelled for maintenance and electronic laboratory personal worked near the source for seven hours before they identify its presence. As soon as the incident was detected a contingency plan was implemented and the source could be retrieved from the tool and placed in its shipping container. The TLD badges indicate doses well below the annual limit of 20 mSv, and none of the workers involved in the incident seem to show serious health consequences from it. After the incident, in order to avoid the occurrence of similar situations, a better source and tool maintenance program was implemented, all the workers were re-trained, and area monitors were installed in all operations bases.

    Full Text Available The component of tourism preparatory parties is to make tourists, whether they are medical or companion, feel more comfortable and bring back home good health attached to good memories. In order to lead a satisfactory discussion primarily wellness and illness tourism concepts are properly described. After explaining their dynamics, factors which are constitutive in these kind of touristic activities, mainly tourists‟ motivations are mentioned. As being a new era of medical tourism, it is shown that facilitators are of great significance. They offer medical value tourism by eliminating too many unknowns for the tourist. Not only empathy but queries also enable highlighting the tourists‟ expectations, experiences and showing the ways of understanding their situation better. New medical hubs and the future ones have to take into account, promote consumer researches that they can advance themselves in the light of new information. The best way to develop well&illness tourism is to make tourist, patient and their companion satisfied with their activities and/or treatment.

  15. Confirmation of a well's mechanical integrity

    International Nuclear Information System (INIS)

    Environmental protection is a major consideration in developing today's offshore resources. Protecting the natural habitat from pollutants is a significant factor in offshore drilling and production. It is also important that shallow, potable water supplies and other important minerals be protected from contamination beneath the surface. Today, wireline techniques can effectively monitor tubular goods and annular cement to determine their capacity to confine potentially harmful materials. The location of corrosion, pits, splits, and other corrosive effects on the inside or outside of tubular goods can be pinpointed, and the magnitude quantitatively evaluated with acceptable accuracy. A system of sectorial evaluation permits the entire tubular periphery to be accurately evaluated for cement shear and hydraulic bond, and to determine if effective zone isolation is established. Data from several test wells and practical field examples support the effectiveness of the sectored, pad-mounted bond log instrument. Recognition of zone isolation and/or hydraulic cement integrity is virtually 100% accurate with the proper measurements, and pinpointing problem areas in a casing string permits effective remedial action to be taken. When conditions are irreparable, the well can be properly plugged and abandoned

    1998-01-01

    When this publisher offered me the opportunity to \\\\Tite a book, some six years ago, I did not hesitate to say yes. I had just spent the last four years of graduate school struggling to understand the physics of strained quantum well lasers, and it seemed to me the whole experience was much more difficult that it should have been. For although many of the results I needed were easy to locate, the underlying physical premises and intervening steps were not. If only I had a book providing the derivations, I could have absorbed them and gone on my way. Such a book lies before you. It provides a unified and self-contained descrip­ tion of the essential physics of strained quantum well lasers, starting from first principles whenever feasible. The presentation I have chosen requires only the standard introductory background in quantum mechanics, solid state physics, and electromagnetics expected of entering graduate students in physics or elec­ trical engineering. A single undergraduate course in each of these su...

  18. Wishes, gender, personality, and well-being.

    1997-03-01

    Study participants (175 men, 230 women) made three wishes and completed measures of the five-factor model of personality, optimism, life satisfaction, and depression. Common wishes were for achievement, affiliation, intimacy, and power as well as for happiness and money. T tests showed women were more likely to wish for improved appearance, happiness, and health; men were more likely to make power wishes and wishes for sex. Among participants who were highly involved in the wishing process, Extraversion was related to making more interpersonal wishes and wishes for positive affect. Neuroticism was related to wishes for emotional stability. Agreeableness and Openness to Experience related to wishes reflective of these traits. Conscientiousness was related to low impulsivity. Depression was related to making highly idiosyncratic, specific wishes, suggesting the use of wishful thinking as a coping mechanism. In addition, happy participants were more likely to rate their wishes as likely to come true. Results indicate that the relatively commonplace process of wishing relates to traits, gender, and well-being. PMID:9143145

  19. Productivity and Injectivity of Horizontal Wells

    Energy Technology Data Exchange (ETDEWEB)

    Khalid Aziz; Sepehr Arababi; Thomas A. Hewett

    1997-04-29

    A general wellbore flow model is presented to incorporate not only frictional, accelerational and gravitational pressure drops, but also the pressure drop caused by inflow. Influence of inflow or outflow on the wellbore pressure drop is analyzed. New friction factor correlations accounting for both inflow and outflow are also developed. The greatest source of uncertainty is reservoir description and how it is used in simulators. Integration of data through geostatistical techniques leads to multiple descriptions that all honor available data. The reality is never known. The only way to reduce this uncertainty is to use more data from geological studies, formation evaluation, high resolution seismic, well tests and production history to constrain stochastic images. Even with a perfect knowledge about reservoir geology, current models cannot do routine simulations at a fine enough scale. Furthermore, we normally don't know what scale is fine enough. Upscaling introduces errors and masks some of the physical phenomenon that we are trying to model. The scale at which upscaling is robust is not known and it is probably smaller in most cases than the scale actually used for predicting performance. Uncertainties in the well index can cause errors in predictions that are of the same magnitude as those caused by reservoir heterogeneities. Simplified semi-analytical models for cresting behavior and productivity predictions can be very misleading.

    2009-05-01

    The experimental results obtained for the magnetotransport in pulsed magnetic fields in the InGaAs/InAlAs double quantum well (DQW) structures of two different shapes of wells and different values of the electron density are reported. The magnetophonon resonance (MPR) was observed for both types of structures within the temperature range 77-125 K. Four kinds of LO phonons are taken into account to interpret the MPR oscillations in the DQW and a method of the Landau level calculation in the DQW is elaborated for this aim. The peculiarity of the MPR in the DQW is the large number of the Landau levels caused by SAS splitting of the electron states (splitting on the symmetric and anti-symmetric states) and the large number of the phonon assistance electron transitions between Landau levels. The significant role of the carrier statistics is shown too. The behavior of the electron states in the DQWs at comparably high temperatures has been studied using the MPR. It is shown that the Huang and Manasreh [Manasreh [Phys. Rev. B 54, 2044 (1996)] model involving screening of exchange interaction is confirmed.

    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 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. PMID:27297503

  2. Pumpernickel Valley Geothermal Project Thermal Gradient Wells

    2006-01-01

    The Pumpernickel Valley geothermal project area is located near the eastern edge of the Sonoma Range and is positioned within the structurally complex Winnemucca fold and thrust belt of north-central Nevada. A series of approximately north-northeast-striking faults related to the Basin and Range tectonics are superimposed on the earlier structures within the project area, and are responsible for the final overall geometry and distribution of the pre-existing structural features on the property. Two of these faults, the Pumpernickel Valley fault and Edna Mountain fault, are range-bounding and display numerous characteristics typical of strike-slip fault systems. These characteristics, when combined with geophysical data from Shore (2005), indicate the presence of a pull-apart basin, formed within the releasing bend of the Pumpernickel Valley – Edna Mountain fault system. A substantial body of evidence exists, in the form of available geothermal, geological and geophysical information, to suggest that the property and the pull-apart basin host a structurally controlled, extensive geothermal field. The most evident manifestations of the geothermal activity in the valley are two areas with hot springs, seepages, and wet ground/vegetation anomalies near the Pumpernickel Valley fault, which indicate that the fault focuses the fluid up-flow. There has not been any geothermal production from the Pumpernickel Valley area, but it was the focus of a limited exploration effort by Magma Power Company. In 1974, the company drilled one exploration/temperature gradient borehole east of the Pumpernickel Valley fault and recorded a thermal gradient of 160oC/km. The 1982 temperature data from five unrelated mineral exploration holes to the north of the Magma well indicated geothermal gradients in a range from 66 to 249oC/km for wells west of the fault, and ~283oC/km in a well next to the fault. In 2005, Nevada Geothermal Power Company drilled four geothermal gradient wells, PVTG-1

    2016-01-01

    We address an eigenvalue problem for the ultrarelativistic (Cauchy) operator $(-\\Delta )^{1/2}$, whose action is restricted to functions that vanish beyond the interior of a unit sphere in three spatial dimensions. We provide high accuracy spectral datafor lowest eigenvalues and eigenfunctions of this infinite spherical well problem. Our focus is on radial and orbital shapes of eigenfunctions. The spectrum consists of an ordered set of strictly positive eigenvalues which naturally splits into non-overlapping, orbitally labelled $E_{(k,l)}$ series. For each orbital label $l=0,1,2,...$ the label $k =1,2,...$ enumerates consecutive $l$-th series eigenvalues. Each of them is $2l+1$-degenerate. The $l=0$ eigenvalues series $E_{(k,0)}$ are identical with the set of even labeled eigenvalues for the $d=1$ Cauchy well: $E_{(k,0)}(d=3)=E_{2 k}(d=1)$. Likewise, the eigenfunctions $\\psi_{(k,0 )}(d=3)$ and $\\psi_{2k }(d=1)$ show affinity. We have identified the generic functional form of eigenfunctions of the spherical we...

    The testing of low permeability rocks is common to waste disposal, fossil energy resource development, underground excavation, and geothermal energy development. This document includes twenty-six papers and abstracts, divided into the following sessions: opening session, case histories and related phenomena, well test design in low permeability formations, analysis and interpretation of well test data, and instrumentation for well tests. Separate abstracts were prepared for 15 of the 16 papers; the remaining paper has been previously abstracted. (DLC)

  6. Spatially indirect excitons in coupled quantum wells

    Microscopic quantum phenomena such as interference or phase coherence between different quantum states are rarely manifest in macroscopic systems due to a lack of significant correlation between different states. An exciton system is one candidate for observation of possible quantum collective effects. In the dilute limit, excitons in semiconductors behave as bosons and are expected to undergo Bose-Einstein condensation (BEC) at a temperature several orders of magnitude higher than for atomic BEC because of their light mass. Furthermore, well-developed modern semiconductor technologies offer flexible manipulations of an exciton system. Realization of BEC in solid-state systems can thus provide new opportunities for macroscopic quantum coherence research. In semiconductor coupled quantum wells (CQW) under across-well static electric field, excitons exist as separately confined electron-hole pairs. These spatially indirect excitons exhibit a radiative recombination time much longer than their thermal relaxation time a unique feature in direct band gap semiconductor based structures. Their mutual repulsive dipole interaction further stabilizes the exciton system at low temperature and screens in-plane disorder more effectively. All these features make indirect excitons in CQW a promising system to search for quantum collective effects. Properties of indirect excitons in CQW have been analyzed and investigated extensively. The experimental results based on time-integrated or time-resolved spatially-resolved photoluminescence (PL) spectroscopy and imaging are reported in two categories. (i) Generic indirect exciton systems: general properties of indirect excitons such as the dependence of exciton energy and lifetime on electric fields and densities were examined. (ii) Quasi-two-dimensional confined exciton systems: highly statistically degenerate exciton systems containing more than tens of thousands of excitons within areas as small as (10 micrometer){sup 2} were

  7. Hydrologic Tests at Characterization Well R-14

    Well R-14 is located in Ten Site Canyon and was completed at a depth of 1316 ft below ground surface (bgs) in August 2002 within unassigned pumiceous deposits located below the Puye Formation (fanglomerate). The well was constructed with two screens positioned below the regional water table. Individual static depths measured for each isolated screen after the Westbay{trademark} transducer monitoring system was installed in mid-December 2002 were nearly identical at 1177 ft bgs, suggesting only horizontal subsurface flow at this time, location, and depth. Screen 1 straddles the geologic contact between the Puye fanglomerate and unassigned pumiceous deposits. Screen 2 is located about 50 ft deeper than screen 1 and is only within the unassigned pumiceous deposits. Constant-rate, straddle-packer, injection tests were conducted at screen 2, including two short tests and one long test. The short tests were 1 minute each but at different injection rates. These short tests were used to select an appropriate injection rate for the long test. We analyzed both injection and recovery data from the long test using the Theis, Theis recovery, Theis residual-recovery, and specific capacity techniques. The Theis injection, Theis recovery, and specific capacity methods correct for partial screen penetration; however, the Theis residual-recovery method does not. The long test at screen 2 involved injection at a rate of 10.1 gallons per minute (gpm) for 68 minutes and recovery for the next 85 minutes. The Theis analysis for screen 2 gave the best fit to residual recovery data. These results suggest that the 158-ft thick deposits opposite screen 2 have a transmissivity (T) equal to or greater than 143 ft{sup 2}/day, and correspond to a horizontal hydraulic conductivity (K) of at least 0.9 ft/day. The specific capacity method yielded a T value equal to or greater than 177 ft{sup 2}/day, and a horizontal K of at least 1.1 ft/day. Results from the injection and recovery phases of the

    This paper presents modeling and simulation results on Si- based quantum-well intersubband THz detectors and THz lasers (tasers) in the 3 to 10 THz range where the intersubband transition energy is 12 to 41 meV. The incoherent cryogenically cooled (4 K to 20 K) quantum well terahertz detector (QWTD) consists of p-type Si0.9Ge0.1 QWs with Si barriers on an Si substrate, or of p-Si0.85Ge0.15/Si on a relaxed Si0.97Ge0.03 buffer on Si. The QWTD senses THz radiation at normal incidence (the XY polarization on the HH1 to LH1 transition) or at edge- illumination (the Z polarization on the HH1 to HH2 transition). Resonant-cavity enhancement, coupling to Si THz waveguides, and integration with SiGe transistor preamplifiers appear feasible for QWTDs. The quantum staircase taser is a simplified far-infrared version of the quantum cascade laser in which each superlattice transfer region is replaced by a thin tunnel-barrier layer. We have adapted to group IV the III-V idea of Sun, Lu, and Khurgin; the `inverted mass taser'. On a Si0.81Ge0.19 substrate, we find that an inverted effective mass exists in LH1 at kg equals 0.013 angstroms-1 in 9-nm single- wells of Si0.7Ge0.3 with 5-nm Si barriers. Selective electrical injection of holes into LH1 at T equals 77 K is postulated. This offers local-in-k-space LH1-HH1 population inversion and tasing at 7.2 THz. Since the taser emission is XY-polarized, the active MQW staircase (a set of identical square QWs) is suitable for insertion into a vertical cavity surface-emitting taser. The VCSET would have resonator thickness of (lambda) /2n equals 6 micrometers , and Bragg mirrors constructed from SiO2/Si multilayers.

  9. Life Goals and Well-Being: Are Extrinsic Aspirations Always Detrimental to Well-Being?

    Ingrid Brdar

    2009-12-01

    Full Text Available Past research has revealed that relative importance a person places on extrinsic life goals as oposed to intrinsic ones is related to lower well-being. But sometimes it is more important why a goal is being pursued than the content of the goal. Materialistic aspirations will not decrease people's well-being if they help them to achieve basic financial security or some intrinsic goals. On the other hand, if social comparison or seeking power drives extrinsic orientation, these aspirations may be detrimental for well-being, since they do not satisfy satisfy our basic psychological needs. Research from Croatia and other, less rich countries suggest that extrinsic aspirations are not necessarily deterimental but may even contribute to well-being. This finding suggests that various factors can moderate the relationship between aspirations and well-being. Intrinsic life goals may probably be affordable only for people who are well off enough. The meaning of financial success in transitional and poor countries may not necesseraly be associated with purchase and consumption. On the contrary, it may bring opportunities and possibilities of self-expression and self-growth. Individualistic societies allow individuals to pursue their intrinsic goals while collectivistic cultures stress extrinsic ones. Although this extrinsic orientation may detract their well-being, the sense of individual well-being may not be as important to them as the survival of the group they belong to or so called social well-being.

    A complete characterization of the structure of nuclei can be obtained by combining information arising from inelastic scattering, Coulomb excitation and $\\gamma-$decay, together with one- and two-particle transfer reactions. In this way it is possible to probe the single-particle and collective components of the nuclear many-body wavefunction resulting from their mutual coupling and diagonalising the low-energy Hamiltonian. We address the question of how accurately such a description can account for experimental observations. It is concluded that renormalizing empirically and on equal footing bare single-particle and collective motion in terms of self-energy (mass) and vertex corrections (screening), as well as particle-hole and pairing interactions through particle-vibration coupling allows theory to provide an overall, quantitative account of the data.

  11. Radionuclide sorption on well construction materials

    International Nuclear Information System (INIS)

    Laboratory experiments were conducted to measure the extent to which trace concentrations of radioactive materials would sorb on well construction materials and to assess the rapidity with which sorption would occur. The radionuclides employed in these studies were tritium, Cs-137, and Co-57. Solutions with trace concentrations of these radionuclides were contacted with casings of PVC, fiber-glass-epoxy, stainless steel, carbon steel, and steel rods coated with epoxy. The PVC showed no interaction with the tritium or Cs-137 during contact times of two hours to three weeks; however, it did sorb Co-57. The fiber-glass-epoxy also interacted only with the cobalt. The stainless steel sorbed cesium and cobalt. The epoxy-coated steel rods did not interact measurably with any of the radionuclides so long as the coating was intact. The sorption reactions generally were apparent after a few days of contact; in the case of carbon steel, they were detectable in a few hours

    The purpose of the invention is to expand the functional possibilities of the sensor by guaranteeing signalling for the decrease in fluid supply. This goal is achieved because the fluid feed sensor of oil wells which contains a spherical reverse valve, inductance coil, arranged in the seat of the reverse valve and connected to the measurement self-generator, whose outlet is connected to the first inlet of the filter mixer, where its second inlet is connected to the reference generator, has a frequency divider with controllable division coefficient and block of frequency comparison, and the inlet of the frequency divider is connected to the outlet of the reference generator, and the outlet is connected to one of the inlets of the frequency comparison block; its other inlet is connected to the outlet of the filter mixer.

    2012-02-01

    Full Text Available In France and in Europe, periurban forests are subject to high social demands for recreational purposes. These demands take the form of frequent visits for sports or rest. Local governments have succeeded in creating new wooded parks close to cities that are highly appreciated by the population. A survey was run on visitors to forests around three mid-sized cities, addressing what they do in the forests and why. The answers revealed differences between suburban parks and larger national forests located farther from the cities. New approaches targeting health may also be observed on the part of both individuals and the health sector. These new approaches indicate the existence of a wellness function in periurban forests.

  15. Well-to-wheel energy analysis study

    International Nuclear Information System (INIS)

    The analysis evaluates separately the fuel cycle (well to tank) and the propulsion (and emission control) systems (tank to wheel). The analysis assessed 75 different fuel pathways (gasoline diesel, Fischer Tropsch diesel, ethanol, methanol, hydrogen, and natural gas) and 15 different propulsion systems (conventional, conventional hybrid, and fuel cell) on a single vehicle type (GM full-size pickup). The results show that in terms of primary energy consumption, petroleum hybrid engines or fuel cell engines are significantly better than most natural gas options and all renewable options. However, in terms of greenhouse gas emissions, fuel-cell vehicles offer a clear edge (although diesel-engine hybrid vehicles are close), but renewable fuel options using ethanol (from biomass fermentation) offer the lowest emissions.

  16. Differential reflectance spectroscopy of quantum well structures

    International Nuclear Information System (INIS)

    Full text: Differential Reflectance Spectroscopy (DR) is a sensitive, non-contact, non-destructive technique for probing the optical characteristics of semiconductor devices. The technique involves measuring the difference in reflectivity between different parts of a sample. When applied to quantum well (QW) structures, this technique displays derivative-like spectra related to the spatial inhomogeneities present. Spatial variations in the sample, whether they be deliberately induced, such as through an ion-implantation/annealing process, or inherent defects, such as a QW width variation, or constituent concentration variations due to growth processes, may be determined using this technique. The sensitivity of DR has been shown to be comparable to or greater than similar techniques such as photoreflectance

  17. Are local wind power resources well estimated?

    Science.gov (United States)

    2013-03-01

    Planning and financing of wind power installations require very importantly accurate resource estimation in addition to a number of other considerations relating to environment and economy. Furthermore, individual wind energy installations cannot in general be seen in isolation. It is well known that the spacing of turbines in wind farms is critical for maximum power production. It is also well established that the collective effect of wind turbines in large wind farms or of several wind farms can limit the wind power extraction downwind. This has been documented by many years of production statistics. For the very large, regional sized wind farms, a number of numerical studies have pointed to additional adverse changes to the regional wind climate, most recently by the detailed studies of Adams and Keith [1]. They show that the geophysical limit to wind power production is likely to be lower than previously estimated. Although this problem is of far future concern, it has to be considered seriously. In their paper they estimate that a wind farm larger than 100 km2 is limited to about 1 W m-2. However, a 20 km2 off shore farm, Horns Rev 1, has in the last five years produced 3.98 W m-2 [5]. In that light it is highly unlikely that the effects pointed out by [1] will pose any immediate threat to wind energy in coming decades. Today a number of well-established mesoscale and microscale models exist for estimating wind resources and design parameters and in many cases they work well. This is especially true if good local data are available for calibrating the models or for their validation. The wind energy industry is still troubled by many projects showing considerable negative discrepancies between calculated and actually experienced production numbers and operating conditions. Therefore it has been decided on a European Union level to launch a project, 'The New European Wind Atlas', aiming at reducing overall uncertainties in determining wind conditions. The

  1. Joint Cross Well and Single Well Seismic Studies at Lost Hills, California

    Energy Technology Data Exchange (ETDEWEB)

    Gritto, Roland; Daley, Thomas M.; Myer, Larry R.

    2002-06-25

    A series of time-lapse seismic cross well and single well experiments were conducted in a diatomite reservoir to monitor the injection of CO{sub 2} into a hydrofracture zone, based on P- and S-wave data. A high-frequency piezo-electric P-wave source and an orbital-vibrator S-wave source were used to generate waves that were recorded by hydrophones as well as three-component geophones. The injection well was located about 12 m from the source well. During the pre-injection phase water was injected into the hydrofrac-zone. The set of seismic experiments was repeated after a time interval of 7 months during which CO{sub 2} was injected into the hydrofractured zone. The questions to be answered ranged from the detectability of the geologic structure in the diatomic reservoir to the detectability of CO{sub 2} within the hydrofracture. Furthermore it was intended to determine which experiment (cross well or single well) is best suited to resolve these features. During the pre-injection experiment, the P-wave velocities exhibited relatively low values between 1700-1900 m/s, which decreased to 1600-1800 m/s during the post-injection phase (-5%). The analysis of the pre-injection S-wave data revealed slow S-wave velocities between 600-800 m/s, while the post-injection data revealed velocities between 500-700 m/s (-6%). These velocity estimates produced high Poisson ratios between 0.36 and 0.46 for this highly porous ({approx} 50%) material. Differencing post- and pre-injection data revealed an increase in Poisson ratio of up to 5%. Both, velocity and Poisson estimates indicate the dissolution of CO{sub 2} in the liquid phase of the reservoir accompanied by a pore-pressure increase. The single well data supported the findings of the cross well experiments. P- and S-wave velocities as well as Poisson ratios were comparable to the estimates of the cross well data. The cross well experiment did not detect the presence of the hydrofracture but appeared to be sensitive to overall

  2. Augmented reality for biomedical wellness sensor systems

    Jenkins, Jeffrey; Szu, Harold

    2013-05-01

    Due to the commercial move and gaming industries, Augmented Reality (AR) technology has matured. By definition of AR, both artificial and real humans can be simultaneously present and realistically interact among one another. With the help of physics and physiology, we can build in the AR tool together with real human day-night webcam inputs through a simple interaction of heat transfer -getting hot, action and reaction -walking or falling, as well as the physiology -sweating due to activity. Knowing the person age, weight and 3D coordinates of joints in the body, we deduce the force, the torque, and the energy expenditure during real human movements and apply to an AR human model. We wish to support the physics-physiology AR version, PPAR, as a BMW surveillance tool for senior home alone (SHA). The functionality is to record senior walking and hand movements inside a home environment. Besides the fringe benefit of enabling more visits from grand children through AR video games, the PP-AR surveillance tool may serve as a means to screen patients in the home for potential falls at points around in house. Moreover, we anticipate PP-AR may help analyze the behavior history of SHA, e.g. enhancing the Smartphone SHA Ubiquitous Care Program, by discovering early symptoms of candidate Alzheimer-like midnight excursions, or Parkinson-like trembling motion for when performing challenging muscular joint movements. Using a set of coordinates corresponding to a set of 3D positions representing human joint locations, we compute the Kinetic Energy (KE) generated by each body segment over time. The Work is then calculated, and converted into calories. Using common graphics rendering pipelines, one could invoke AR technology to provide more information about patients to caretakers. Alerts to caretakers can be prompted by a patient's departure from their personal baseline, and the patient's time ordered joint information can be loaded to a graphics viewer allowing for high

    1984-02-07

    An end fitting for a sucker rod for oil wells is described with the end fitting having a chamber portion extending inwardly from one end thereof and an externally threaded portion at its other end. The chamber portion is defined by a plurality of spaced-apart annular ridges which define frusto-conical shaped cavities therebetween. The end fitting also has a bore extending inwardly thereinto from its other end which communicates with the inner end of the chamber portion. A valve is mounted in the end fitting and has a valve stem positioned in the bore and a valve head positioned at the inner end of the chamber portion. The chamber portion is adapted to receive a glass reinforced resin bonded cylindrical rod which is maintained therein by a two-part epoxy resin which surrounds the rod and is received in the cavities to form epoxy wedges bonded to the rod. The outer end of the bore is provided with internal threads which threadably receive a screw therein which engages the end of the valve stem so that longitudinal force may be applied to the valve thereby transmitting longitudinal force to the end of the rod.

  6. Geophysical well logging using nuclear techniques

    International Nuclear Information System (INIS)

    Nuclear logging of boreholes is in world-wide use for locating and evaluating commercial deposits of hydrocarbons, coal, uranium and certain other useful minerals. Within the petroleum industry the principal uses of nuclear logs are for correlation between wells, for measuring the porosity of rocks, for identifying hydrocarbons and for determining rock type. The long-spaced, dual detector neutron log is especially used to measure porosity and, in combination with a scattered gamma-ray density log to identify gas. Small-diameter borehole accelerators are used as sources of pulsed 14-MeV neutrons to make routinely neutron die-away logs to distinguish hydrocarbons from salt water in cased holes. New accelerator logs based on spectral gamma-ray measurements are being developed to distinguish hydrocarbons from fresh water and to improve lithology determinations. Natural gamma-ray spectral measurements are used to solve correlation problems and to identify uranium-, thorium- and potassium-rich minerals. In coal exploration natural gamma-ray and scattered gamma-ray density logs are used to locate the coal and, in favourable circumstances, to estimate ash content. For oil shale evaluation the density log has been used in small-diameter holes in Colorado oil shale to determine potential oil yield. A new method of uranium detection based on measurement of delayed fission neutrons produced by bombardment of the formations with 14-MeV neutrons from a pulsed accelerator source has recently been described.

  7. Predicting reservoir wettability via well logs

    2016-06-01

    Wettability is an important factor in controlling the distribution of oil and water. However, its evaluation has so far been a difficult problem because no log data can directly indicate it. In this paper, a new method is proposed for quantitatively predicting reservoir wettability via well log analysis. Specifically, based on the J function, diagenetic facies classification and the piecewise power functions, capillary pressure curves are constructed from conventional logs and a nuclear magnetic resonance (NMR) log respectively. Under the influence of wettability, the latter is distorted while the former remains unaffected. Therefore, the ratio of the median radius obtained from the two kinds of capillary pressure curve is calculated to reflect wettability, a quantitative relationship between the ratio and reservoir wettability is then established. According to the low-permeability core sample capillary pressure curve, NMR {{T}2} spectrum and contact angle experimental data from the bottom of the Upper Triassic reservoirs in western Ordos Basin, China, two kinds of constructing capillary pressure curve models and a predictive wettability model are calibrated. The wettability model is verified through the Amott wettability index and saturation exponent from resistivity measurement and their determined wettability levels are comparable, indicating that the proposed model is quite reliable. In addition, the model’s good application effect is exhibited in the field study. Thus, the quantitatively predicting reservoir wettability model proposed in this paper provides an effective tool for formation evaluation, field development and the improvement of oil recovery.

  8. The economics of well-being.

    2012-01-01

    Gross domestic product has long been the chief measure of national success. But there's been a lot of talk lately about changing that, from economists and world leaders alike. GDP is under siege for three main reasons. First, it is flawed even on its own terms: It misses lots of economic activity (unpaid household work, for example) and, as a single-number representation of vast, complex systems, is inevitably skewed. Second, it fails to account for economic and environmental sustainability. And third, readily available alternative measures may reflect well-being far better, by taking into account factors such as educational achievement, health, and life expectancy. HBR's Justin Fox surveys historical and current views on how to assess national progress, from Jeremy Bentham to Robert Kennedy to Nicolas Sarkozy. He also looks at where we may be headed. The biggest success so far in the campaign to supplant or at least supplement GDP, he finds, is the UN's Human Development Index-on which the United States has never claimed the top spot.

    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.

    2012-01-01

    Excited states in 38,40,42Si nuclei have been studied via in-beam gamma-ray spectroscopy with multi-nucleon removal reactions. Intense radioactive beams of 40S and 44S provided at the new facility of the RIKEN Radioactive Isotope Beam Factory enabled gamma-gamma coincidence measurements. A prominent gamma line observed with an energy of 742(8) keV in 42Si confirms the 2+ state reported in an earlier study. Among the gamma lines observed in coincidence with the 2+ -> 0+ transition, the most probable candidate for the transition from the yrast 4+ state was identified, leading to a 4+_1 energy of 2173(14) keV. The energy ratio of 2.93(5) between the 2+_1 and 4+_1 states indicates well-developed deformation in 42Si at N=28 and Z=14. Also for 38,40Si energy ratios with values of 2.09(5) and 2.56(5) were obtained. Together with the ratio for 42Si, the results show a rapid deformation development of Si isotopes from N=24 to N=28.

  11. Well logging with natural gamma radiation

    International Nuclear Information System (INIS)

    An invention is described for use in natural gamma radiation well logging in which measurements taken in a borehole are used in the search for valuable underground resources such as oil or gas. The invention comprises deriving a log of natural gamma radiation detected in selected energy windows for a selected borehole depth interval and converting it into a log of the selected subsurface materials, e.g. Th, U, K. This log is corrected for the effects of 1) either a gamma ray emitter in the borehole fluid, e.g. potassium salts and/or 2) a gamma ray attenuator in the borehole fluid, e.g. a strong attenuator such as barite and/or hematite. The Th, U, K log is particularly useful in the exploration of oil and gas resources since the Th, U, K concentrations are a good indication as to the presence, type and volume of shale and clay in the formations surrounding the borehole.

    2010-02-01

    We present a study on quasibound states in multiple quantum well structures using a finite element model (FEM). The FEM is implemented for solving the effective mass Schrödinger equation in arbitrary layered semiconductor nanostructures with an arbitrary applied potential. The model also includes nonparabolicity effects by using an energy dependent effective mass, where the resulting nonlinear eigenvalue problem was solved using an iterative approach. We focus on quasibound/continuum states above the barrier potential and show that such states can be determined using cyclic boundary conditions. This new method enables the determination of both bound and quasibound states simultaneously, making it more efficient than other methods where different boundary conditions have to be used in extracting the relevant states. Furthermore, the new method lifted the problem of quasibound state divergence commonly seen with many other methods of calculation. Hence enabling accurate determination of dipole matrix elements involving both bound and quasibound states. Such calculations are vital in the design of intersubband optoelectronic devices and reveal the interesting properties of quasibound states above the potential barriers.

    2005-01-01

    Based on the flow mechanism of hydraulic fractured wells, through integrating linear-flow model and effective well-radius model, a new model of well test analysis for wells with vertical fracture was established. In the model, wellbore storage, the damage in the wall of fracture and all kinds of boundary conditions are considered. The model is concise in form, has intact curves and computes fast, which may meet the demand of realtime computation and fast responded well test interpretation. A new method to determine effective well radius was presented, and the correlation between effective well radius and the fracture length, fracture conductivity, skin factor of fracture was given. Matching flow rate or pressure tested, the optimization model that identified formation and fracture parameters was set up. The automatic matching method was presented by synthetically using step by step linear least square method and sequential quadratic programming. At last, the application was also discussed. Application shows that all of these results can analyze and evaluate the fracturing treatment quality scientifically and rationally, instruct and modify the design of fracturing and improve fracturing design level.

    We develop an accumulatively effective and affordable set of smart pair devices to save the exuberant expenditure for the healthcare of aging population, which will not be sustainable when all the post-war baby boomers retire (78 millions will cost 1/5~1/4 GDP in US alone). To design an accessible test-bed for distributed points of homecare, we choose two exemplars of the set to demonstrate the possibility of translation of modern military and clinical know-how, because two exemplars share identically the noninvasive algorithm adapted to the Smart Sensor-pairs for the real world persistent surveillance. Currently, the standard diagnoses for malignant tumors and diabetes disorders are blood serum tests, X-ray CAT scan, and biopsy used sometime in the physical checkup by physicians as cohort-average wellness baselines. The loss of the quality of life in making second careers productive may be caused by the missing of timeliness for correct diagnoses and easier treatments, which contributes to the one quarter of human errors generating the lawsuits against physicians and hospitals, which further escalates the insurance cost and wasteful healthcare expenditure. Such a vicious cycle should be entirely eliminated by building an "individual diagnostic aids (IDA)," similar to the trend of personalized drug, developed from daily noninvasive intelligent databases of the "wellness baseline profiling (WBP)". Since our physiology state undulates diurnally, the Nyquist anti-aliasing theory dictates a minimum twice-a-day sampling of the WBP for the IDA, which must be made affordable by means of noninvasive, unsupervised and unbiased methodology at the convenience of homes. Thus, a pair of military infrared (IR) spectral cameras has been demonstrated for the noninvasive spectrogram ratio test of the spontaneously emitted thermal radiation from a normal human body at 37°C temperature. This invisible self-emission spreads from 3 microns to 12 microns of the radiation wavelengths

  16. Systemic lupus erythematosus associated with Wells' syndrome.

    2012-04-01

    Wells' syndrome is a multifaceted dermatosis with a wide morphological spectrum, ranging from characteristic cellulitis-like erythema and papula to an unusual presentation of vesicles and pustules. The most important elements for diagnosis are erythemal plaques and histological picture of eosinophilic infiltration of the dermis with 'flame figures' (Plotz et al., in Hautarzt 51:182-186, 2000). Because of its original description as a distinct entity, it has come to be regarded as an abnormal eosinophilic response to a number of causative agents such as herpes simplex virus 2(HSV-2) and toxocara (Ludwig et al., in J Am Acad Dermatol 48:S60-S61, 2003; Bassukas et al., in Cases J 1:356, 2008). Concurrence of WS and malignant diseases as colon cancer, trachea squamous carcinoma, nasopharyngeal carcinoma or angioimmunoblastic lymphadenopathy has been reported (Hirsch et al., in J Dtsch Dermatol Ges 3:530-531, 2005; Renner et al., in Acta Derm Venereol 87:525-528, 2007). Autoimmune diseases, including Systemic lupus erythematosus (SLE) are multi-system disorders of unknown cause and are commonly characterized by protean cutaneous manifestations. To date, few autoimmne disease was found associated with WS except four previous reports of Churg-Strauss syndrome (CSS) and one case of ulcerative colitis (Fujimoto et al., in Clin Exp Dermatol, 2010; Sakaria et al., in J Gastroenterol 42:250-252, 2007). The coexistence of SLE and WS in one patient was not found in literature and our case is the first. Here we described the rare combination and discussed the treatment strategy for this condition.

  17. Bioenergy: Doing well while doing right

    International Nuclear Information System (INIS)

    Bioenergy - growing one's own fuel - offers the opportunity to do well while doing right. For several decades, the United States has promoted development of ethanol because it offers multiple national benefits - aiding farmers, the environment and the nation's energy security. But we have only scratched the surface of bioenergy's promise. Most ethanol is produced from corn, using only the starch in the kernels. But new conversion technologies could lead to the cost-effective use of a wide variety of feedstocks and agricultural waste products like corn stalks and wheat straw to produce ethanol and other products, such as chemicals and plastics, that are currently derived from fossil fuels. These technologies allow farmers to harvest double dividends - selling cash crops like corn and wheat, and converting the leftover 'waste' to fuel for the transportation sector. Bioenergy's potential is huge - economically and environmentally. Currently, ethanol accounts for less than 2 per cent of US gas consumption. The new bioenergy technologies could dramatically increase that figure, producing as much as 150 billion litres - the equivalent of one quarter of our current gasoline use. Bioenergy will also help prevent further global warming because the carbon dioxide emitted as it is produced and used is absorbed by the plants as they grow. The net greenhouse gas emissions are near zero. Moreover, bioenergy could spur economic development around the world. Advanced ethanol technologies will provide poor countries with a new way to meet transportation needs that are necessary prerequisites to economic progress and growth. With the right technology and basic training, these countries will be able to grow their own fuels, allowing them to redirect scarce foreign exchange earnings away from imported oil to more productive national investments - including critical social investments in health, education and welfare

  5. Boys and girls who reason well mathematically.

    Science.gov (United States)

    Stanley, J C

    1993-01-01

    Since 1971 the Study of Mathematically Precocious Youth (SMPY) at Johns Hopkins University has pioneered in discovery of and provision of educational help for 12-year-old boys and girls who reason better mathematically than 99% of other 12-year-olds. SMPY originated widespread searches for such youths and special academic classes for them outside the regular school system. A regional talent search, verbal as well as mathematical, now covers all 50 states of the USA, and many varied residential summer programmes are offered across the country. These have provided educational facilitation for many thousands, and have encouraged greater curricular flexibility in schools and better articulation of in-school with out-of-school learning experiences. From the first talent search conducted by SMPY in 1972, it became obvious that boys tend to score considerably higher than girls on the College Board Scholastic Aptitude Test-Mathematical (SAT-M), a test intended mainly for college-bound 17- and 18-year-olds. This difference was reported in 1974 but attracted little attention until a controversial report in 1980 stimulated research on sex differences in various aspects of mathematics. Here I describe a study of sex differences over 10 years on 14 College Board high school achievement tests, which are taken (three usually) by bright 17- and 18-year-olds seeking admission to the USA's selective colleges and universities. Among the high scores on the European history test the ratio of males to females was greatest, 6:1. The next most sex-differentiating test was physics, 2.9:1, followed by elementary-level mathematics (mainly algebra and geometry), 2.5:1. Other ratios favouring males were, in 1991, chemistry (2.4:1), American history (2.1:1), biology (1.8:1), precalculus mathematics (1.6:1), Latin (1.6:1), French (1.4:1), modern Hebrew (1.1:1) and German (1.02:1). Tests in which more females were high scorers were literature (1.26:1), English composition (1.05:1) and Spanish (1

  6. THE IMPACT OF THE PRODUCTION OF NEIGHBOUR WELLS ON WELL PRODUCTIVITY IN A SHALE GAS RESERVOIR

    Directory of Open Access Journals (Sweden)

    Asri Nugrahanti

    2014-05-01

    Full Text Available ABSTRACT: A shale gas reservoir is a self-contained source-reservoir system, characterized by extremely low matrix-permeability and low porosity, which typically requires extensive fracturing to produce gas at commercial rates. This paper presents a simulation experiment, intended to study the impact of well interference on gas recovery in a shale gas reservoir. The simulation model was constructed to study well interference through variation of horizontal well length, fracture half length, number of fracture, and well spacing. The results show that the increment of recovery factor of a well in the presence of neighbour wells is up to 7%. In this study, fracture half length is the most influence parameter on recovery factor, initial rate and reservoir pressure decline.

  8. Well completion report on installation of horizontal wells for in-situ remediation tests

    International Nuclear Information System (INIS)

    A project to drill and install two horizontal vapor extraction/air-injection wells at the Savannah River Site (SRS), Aiken, South Carolina, was performed in September and October of 1988. This study was performed to test the feasibility of horizontal drilling technologies in unconsolidated sediments and to evaluate the effectiveness of in-situ air stripping of volatile organics from the ground water and unsaturated soils. A tremendous amount of knowledge was obtained during the drilling and installation of the two test wells. Factors of importance to be considered during design of another horizontal well drilling program follow. (1) Trips in and out of the borehole should be minimized to maintain hole stability. No reaming to enlarge the hole should be attempted. (2) Drilling fluid performance should be maximized by utilizing a low solids, low weight, moderate viscosity, high lubricity fluid. Interruption of drilling fluid circulation should be minimized. (3) Well materials should possess adequate flexibility to negotiate the curve. A flexible guide should be attached to the front of the well screen to guide the screen downhole. (4) Sands containing a minor amount of clay are recommended for completion targets, as better drilling control in the laterals was obtained in these sections

  9. Well test imaging - a new method for determination of boundaries from well test data

    Energy Technology Data Exchange (ETDEWEB)

    Slevinsky, B.A.

    1997-08-01

    A new method has been developed for analysis of well test data, which allows the direct calculation of the location of arbitrary reservoir boundaries which are detected during a well test. The method is based on elements of ray tracing and information theory, and is centered on the calculation of an instantaneous {open_quote}angle of view{close_quote} of the reservoir boundaries. In the absence of other information, the relative reservoir shape and boundary distances are retrievable in the form of a Diagnostic Image. If other reservoir information, such as 3-D seismic, is available; the full shape and orientation of arbitrary (non-straight line or circular arc) boundaries can be determined in the form of a Reservoir Image. The well test imaging method can be used to greatly enhance the information available from well tests and other geological data, and provides a method to integrate data from multiple disciplines to improve reservoir characterization. This paper covers the derivation of the analytical technique of well test imaging and shows examples of application of the technique to a number of reservoirs.

  10. On the straight and narrow : well guidance system keeps vertical wells on track

    Energy Technology Data Exchange (ETDEWEB)

    Mahony, J.

    2009-11-15

    Small deviations in vertical legs of wellbores can often create significant problems, whether drilling, tripping or moving hardware into the well. As a result, different tools have been developed to navigate or avoid crooked holes. These systems usually rely on guidance tools, such as measurement-while-drilling (MWD), to keep well trajectories straight, However, rotary steerables are often costly. This article discussed a tool entitled the G-Force vertical guidance tool, that offers similar benefits of other toolmakers, but for approximately half the cost. G-Force uses three stabilizers and a positive displacement mud motor to guide the bit during drilling and correct any deviation in well trajectory. The benefits, features, and applications of the G-Force technology were outlined. It was concluded that G-Force offers effective torque and has a slight bend in vibration, that enables the bit to hum. It allows for important target control by operators. 1 fig.

  12. WELL-94: a stylized well scenario for indicative dose assessment of deep repositories

    International Nuclear Information System (INIS)

    WELL-94 is a stylized well scenario aimed to be used as an indicator in assessing the performance of the near-field and geosphere barriers of a deep repository for nuclear waste. It converts the release rates of radionuclides from the repository into the geosphere or from the geosphere into the biosphere into a dose rate. The scenario is based on an assumption that the annual releases from the repository into the biosphere are diluted in 100 000 m3 of water and an individual drinks 500 litres of contaminated water per year. Drinking of water is the only exposure pathway considered. (12 refs., 4 tabs.)

    2016-02-01

    Full Text Available Deep geothermal heat pump systems have considerable energy saving potential for heating and cooling systems that use stable ground temperature and groundwater as their heat sources. However, deep geothermal systems have several limitations for real applications such as a very high installation cost and a lack of recognition as heating and cooling systems. In this study, we performed a feasibility assessment of a Standing Column Well (SCW system using a deep geothermal well, based on a real-scale experiment in Korea. The results showed that the temperature of the heat source increased up to 42.04 °C in the borehole after the heating experiment, which is about 30 °C higher than that of normal shallow geothermal wells. Furthermore, the coefficient of performance (COP of the heat pump during 3 months of operation was 5.8, but the system COP was only 3.6 due to the relatively high electric consumption of the pump. Moreover, the payback period of the system using a deep well for controlled horticulture in a glass greenhouse was calculated as 6 years compared with using a diesel boiler system.

    Bird, Philip H.

    2006-01-01

    Borehole geophysical logging and aquifer-isolation (packer) tests were conducted in well MG-1693 (NP-87) at the North Penn Area 5 Superfund Site near Colmar, Montgomery County, Pa. Objectives of the study were to identify the depth and yield of water-bearing zones, occurrence of vertical borehole flow, and effects of pumping on water levels in nearby wells. Caliper, natural-gamma, single-point-resistance, fluid-temperature, fluid-resistivity, heatpulse-flowmeter, and borehole-video logs were collected. Vertical borehole-fluid movement direction and rate were measured under nonpumping conditions. The suite of logs was used to locate water-bearing fractures, determine zones of vertical borehole-fluid movement, and select depths to set packers. Aquifer-isolation tests were conducted to sample discrete intervals and to determine specific capacities of water-bearing zones and effects of pumping individual zones on water levels in two nearby monitor wells. Specific capacities of isolated zones during aquifer-isolation tests ranged from 0.03 to 3.09 (gal/min)/ft (gallons per minute per foot). Fractures identified by borehole geophysical methods as water-producing or water-receiving zones produced water when isolated and pumped. Water enters the borehole primarily through high-angle fractures at 416 to 435 ft bls (feet below land surface) and 129 to 136 ft bls. Water exits the borehole through a high-angle fracture at 104 to 107 ft bls, a broken casing joint at 82 ft bls, and sometimes as artesian flow through the top of the well. Thirteen intervals were selected for aquifer-isolation testing, using a straddle-packer assembly. The specific capacity of interval 1 was 2.09 (gal/min)/ft. The specific capacities of intervals 2, 3, and 4 were similar: 0.27, 0.30, and 0.29 (gal/min)/ft,respectively. The specific capacities of intervals 5, 6, 7, 8, and 10 were similar: 0.03, 0.04, 0.09, 0.09, and 0.04 (gal/min)/ft,respectively. Intervals 9, 11, and 12 each showed a strong

    2011-10-01

    In this study, both the linear intersubband transitions and the refractive index changes in coupled double quantum well (DQW) with different well shapes for different electric fields are theoretically calculated within framework of the effective mass approximation. Results obtained show that intersubband transitions and the energy levels in coupled DQW can importantly be modified and controlled by the electric field strength and direction. By considering the variation of the energy differences, it should point out that by varying electric field we can obtain a blue or red shift in the intersubband optical transitions. The modulation of the absorption coefficients and the refractive index changes which can be suitable for good performance optical modulators and various infrared optical device applications can be easy obtained by tuning applied electric field strength and direction.

  3. Resident Wellness Matters: Optimizing Resident Education and Wellness Through the Learning Environment.

    Science.gov (United States)

    Jennings, M L; Slavin, Stuart J

    2015-09-01

    The problem of poor mental health in residency is well established. Burnout, depression, and suicidal ideation are prevalent among resident physicians, and these problems appear to persist into practice. Leaders in graduate medical education such as policy makers at the Accreditation Council for Graduate Medical Education (ACGME) and directors of individual programs and institutions should acknowledge these important issues and take steps to address them. The ACGME's Clinical Learning Environment Review (CLER) Program currently outlines an expectation that institutions both educate residents about burnout and measure burnout annually. The CLER Program could go further by expecting institutions to create quality initiatives to enhance resident wellness and increase resident engagement. The ACGME should also call for and support research in this area. Leaders or directors of individual programs and institutions should consider wellness initiatives that both (1) identify and address suboptimal aspects of the learning environment and (2) train residents in resilience skills. Efforts to improve the residency learning environment could be guided by the work of Maslach and Leiter, who describe six categories of work stress that can contribute to burnout: (1) workload, (2) control, (3) balance between effort and reward, (4) community, (5) fairness, and (6) values.

    A method of designing and analyzing pressure transient well tests of two-phase (steam-water) reservoirs is given. Wellbore storage is taken into account and the duration of it is estimated. It is shown that the wellbore flow can completely dominate the downhole pressure signal such that large changes in the downhole pressure that might be expected because of changes in kinematic mobility are not seen. Changes in the flowing enthalpy from the reservoir can interact with the wellbore flow so that a temporary plateau in the downhole transient curve is measured. Application of graphical and non-graphical methods to determine reservoir parameters from drawdown tests is demonstrated.

    More than two decades ago, Fritjof Capra commended - and indeed advocated – a paradigm shift in health science and care. In his book The Turning Point (1982 he talks of a major shift from the preoccupation with micro-organisms to a careful study of the ‘host organism and its environment’, of ‘significant attempts to develop a unified approach to the mind/body system’ in Western medicine, of  ‘a new holistic paradigm’ (as opposed to ‘the old biomedical paradigm’ regarding the problem of health and healing, of ‘a holistic and humanistic approach to primary care’, and of ‘a holistic therapy’ as opposed to ‘the traditional biochemical practice of associating a physical disease with a specific physical cause’. Our concern in this article is with the paradigm shift advocated by Capra in this book and the progress that has since been made.

    Opsomming

    Meer as twee dekades gelede het Fritjof Capra ‘n pleidooi gelewer vir ‘n paradigmaskuif vanaf die bio- mediese model na ‘n meer holistiese, ekosistemiese model van gesondheid en genesing. Die vraag wat in hierdie artikel aan die orde kom is of praktisyns in die veld van die gesondheidswetenskappe sedertdien daarin geslaag het om die oorgang na die aanbevole paradigma te maak. ‘n Oorsig van die literatuur sedert 1982 toon dat die skuif nog nie regtig gemaak is nie. ‘n Ander literatuuroorsig toon voorts dat die terme ‘gesondheid’, ‘well-being’ en ‘wellness’ as uitruilbaar beskou word en dat hulle betekenisse meermale afhang van die gebruikskonteks. Op grond van hulle bespreking van die antropologiese ekosistemiese benadering tot gesondheid en genesing stel die outeurs voor dat die terme ‘gesondheid’ en ‘wellness’ as korrelatiewe gebruik word, en dat die term ‘well-being’ gebruik word vir al die domeine van menslike lewe en bestaan wat kan bydra tot gesondheid, oftewel ‘wellness’.

  6. The finite square well: whatever is worth teaching at all is worth teaching well

    A contemporary physicist would be hard put to agree entirely with the author of a 1959 textbook on quantum mechanics, who wrote: "A second simple, one-dimensional system, somewhat divorced from reality but illustrative of the principles of the theory, is a particle in a box with finite walls." Interest in this prototypic system has not diminished over the years, and is not likely to do so in the near future, because it has now been wedded to reality and seen as a paradigm for quantum wells and other nanosystems. The treatment of this topic in standard textbooks has changed little over the last few decades, and such changes as have come to our notice leave, in our opinion, much to be desired. The purpose of this article is to enable, even encourage, other teachers to give the finite square well the attention that it deserves; to this end, the authors provide a tutorial review that is more instructive and comprehensive than the accounts presented in numerous textbooks and dispensed in still more numerous online...

  8. Analysis of unit mobility ratio well-to-well tracer flow to determine reservoir heterogeneity

    Energy Technology Data Exchange (ETDEWEB)

    Abbaszadeh-Dehghani, M.; Brigham, W.E.

    1983-02-01

    This study has been carried out in two related sections. In the first section, exact analytic equations have been derived to define breakthrough curves for different developed flooding well patterns for unit mobility ratio. The first section also includes an extension of an analytical definition of pattern breakthrough curves for mobility ratio other than one. The second part discusses flow of a tracer slug in various patterns. In each system, the longitudinal mixing of the tracer slug in a general streamtube of the pattern has been formulated mathematically. A line integral along a streamtube was derived which represents the length of the mixed zone. When this line integral was substituted into the mixing equation, an expression for the concentration of tracer at any location within a streamtube resulted. The study shows that the effluent tracer concentration depends upon the pattern geometry and size, and the dispersion constant of the formation. Tracer production curves for the different patterns considered have also been correlated into a set of curves depending on a/..cap alpha.., (a = distance between like wells, ..cap alpha.. = dispersion constant). The correlation was achieved by deriving two sets of correction factors, one for tracer peak concentration, and another for a/..cap alpha.. ratio. As a result of this correlation, a tracer response from any repeated homogeneous pattern can be estimated from the response of an equivalent five-spot system by utilizing the correction factors. A computer program based on a non-linear optimization technique was developed which decomposes a detected tracer breakthrough profile from a multilayered system into responses from individual layers. The algorithm utilizes the equations of the five-spot pattern in conjunction with the developed correction factors. A five-spot field example which has been successfully decomposed into several layers is shown to illustrate the use of this research. 42 figures, 15 tables.

    Full Text Available For optimization well-type on the conditions of basal groundwater, inasmuch as an analogy exists between electrical and fluid flow, the electrolytic analogy experiments have been conducted, which made a series of comparisons and evaluations between 9 types of complex well configurations and vertical well in terms of production. Taking into account the boundary condition of basal groundwater, we conducted 3×3×10 experiments in totally, including vertical well, horizontal well, radial well, snaky well, 3 types of fishbone well and 3 types of multilateral well. The experiment of every well mentioned above was conducted on the voltage values of 2V, 3V, 4V and conductibility values of 90μs/cm, 200μs/cm, 350μs/cm respectively. And then, specific settings were made for the stimulated well-types and reservoirs in order to make evaluations. The results indicate that production range in a diminishing sequence from horizontal well, 60°-fishbone well, 90°-fishbone well, 30°-fishbone well, 4-lateral Well, snaky well, radial well, 3-lateral Well, 2-lateral Well to vertical well. In the meantime, proposed the conception of radio of production and that even if changed the voltage value, the radio of production changed little for some specific well-types under the condition of the same resistivity. Utilizing the conclusion above, the production of complex well configurations’s transformed from vertical wells can be calculated in specific conditions of the reservoir. The obtained experimental conclusions are useful for engineers and researchers to verify their analytical production model exactly and computer codes.

  15. TWRS privatization phase 1 monitoring wells engineering study

    International Nuclear Information System (INIS)

    This engineering study provides an evaluation of existing wells and boreholes (wells) within the proposed location for the Tank Waste Remediation System (TWRS) Privatization Phase 1 demonstration site. Phase 1 is part of the TWRS program that was established to manage, retrieve, treat, immobilize, and dispose of high-level waste stored in underground tanks at the Hanford Site. This evaluation is to determine which wells will remain active within the demonstration site based on regulatory, programmatic, or other beneficial use requirements. An initial evaluation of wells within the demonstration site was conducted in 1996. However, changes in construction plans and expansion of the demonstration site necessitated a reevaluation and reclassification of the wells that are within the expanded site. Impacted wells include many of those previously evaluated as well as additional wells identified in or near the expansion areas. Thirty-three wells exist within and immediately adjacent to the identified boundary of the proposed demonstration site. The wells identified for decommissioning will be abandoned according to the well decommissioning plan. Future well requirements within the site include replacement wells for those wells impacted by construction activities, replacements for Resource Conservation and Recovery Act of 1976 (RCRA) wells going dry, and a new characterization well installed to support a TWRS Phase 2 site assessment

  18. Improving reservoir performance using new 'smart' well technology

    International Nuclear Information System (INIS)

    The technologies that were available in the past to improve reservoir performance include 3-D seismic, coiled tubing, horizontal wells, and PCP's. Future enabling technologies will also include multi-lateral wells, 'smart' wells, underbalanced drilling, and downhole fluids processing. A description of 'smart' well technology was given, defined as well completions which facilitate downhole monitoring and control of production to achieve maximum reserves recovery. The current development for 'smart' wells is focused on offshore and subsea wells for marginal field development and work-over mitigation, with the emphasis in system design for production control of horizontal and multi-lateral wells. Basic 'smart' well configuration, instrumentation and monitoring systems, applications of 'smart' well technology in the Western Canadian Sedimentary Basin, and future developments and applications for the technology in general, were also discussed. 30 figs

    Fatigue of wellhead at subsea-completed wells is a growing problem in the offshore industry. It has been a large technology development in the offshore industry. This has resulted in an extension in the expected life for subsea wells. This partly due to new technology which allow for drilling of more and more complex side-tracks in already existing wells and the considerably well maintenance performed to extend the production phase of the subsea wells. Despite the technology development the s...

  20. Performance of horizontal versus vertical vapor extraction wells

    International Nuclear Information System (INIS)

    Vapor extraction wells used for site remediation of volatile organic chemicals in the vadose zone are typically vertical wells. Over the past few years, there has been an increased interest in horizontal wells for environmental remediation. Despite the interest and potential benefits of horizontal wells, there has been little study of the relative performance of horizontal and vertical vapor extraction wells. This study uses numerical simulations to investigate the relative performance of horizontal versus vertical vapor extraction wells under a variety of conditions. The most significant conclusion that can be drawn from this study is that in a homogeneous medium, a single, horizontal vapor extraction well outperforms a single, vertical vapor extraction well (with surface capping) only for long, linear plumes. Guidelines are presented regarding the use of horizontal wells
