The probability distributions of external-corrosion pit depth and pit growth rate were investigated in underground pipelines using Monte Carlo simulations. The study combines a predictive pit growth model developed by the authors with the observed distributions of the model variables in a range of soils. Depending on the pipeline age, any of the three maximal extreme value distributions, i.e. Weibull, Frechet or Gumbel, can arise as the best fit to the pitting depth and rate data. The Frechet distribution best fits the corrosion data for long exposure periods. This can be explained by considering the long-term stabilization of the diffusion-controlled pit growth. The findings of the study provide reliability analysts with accurate information regarding the stochastic characteristics of the pitting damage in underground pipelines.

Our city has owned the integrated pipeline network management system with ArcGIS Engine 9.1 as the bottom development platform and with Oracle9i as basic database for storaging data. In this system, ArcGIS SDE9.1 is applied as the spatial data engine, and the system was a synthetic management software developed with Visual Studio visualization procedures development tools. As the pipeline update function of the system has the phenomenon of slower update and even sometimes the data lost, to ensure the underground pipeline data can real-time be updated conveniently and frequently, and the actuality and integrity of the underground pipeline data, we have increased a new update module in the system developed and researched by ourselves. The module has the powerful data update function, and can realize the function of inputting and outputting and rapid update volume of data. The new developed module adopts Visual Studio visualization procedures development tools, and uses access as the basic database to storage data. We can edit the graphics in AutoCAD software, and realize the database update using link between the graphics and the system. Practice shows that the update module has good compatibility with the original system, reliable and high update efficient of the database.

Pipeline scales from the Campos Bay Petroleum Field near Rio de Janeiro, Brazil have been analyzed by both Raman spectroscopy and by laser-induced breakdown spectroscopy (LIBS) using a double-pulse, calibration-free approach. Elements that are characteristic of petroleum (e.g. C, H, N, O, Mg, Na, Fe and V) were detected, in addition to the Ca, Al, and Si which form the matrix of the scale. The LIBS results were compared with the results of micro-Raman spectroscopy, which confirmed the nature of the incrustations inferred by the LIBS analysis. Results of this preliminary study suggest that diffusion of pipe material into the pipeline intake column plays an important role in the growth of scale. Thanks to the simplicity and relative low cost of equipment and to the fact that no special chemical pre-treatment of the samples is needed, LIBS can offer very fast acquisition of data and the possibility of in situ measurements. LIBS could thus represent an alternative or complementary method for the chemical characterization of the scales by comparison to conventional analytical techniques, such as X-ray diffraction or X-ray fluorescence. - Highlights: • Samples of scales from petroleum pipelines were analyzed using double pulse LIBS. • LIBS is proposed as an alternative method to conventional analytical techniques. • The scale growth is influenced by the product of corrosion in the column of production. • The diffusion of pipe material into the inlay is important for the growth of scale

A leaking water pipe bursting high pressure water jet in the soil will create slurry erosion which will eventually erode the adjacent natural gas pipe, thus causing its failure. The standard 300 mm safety distance used to place natural gas pipe away from water pipeline facilities needs to be reviewed to consider accidental damage and provide safety cushion to the natural gas pipe. This paper presents a study on underground natural gas pipeline safety distance via experimental and numerical approaches. The pressure–distance characteristic curve obtained from this experimental study showed that the pressure was inversely proportional to the square of the separation distance. Experimental testing using water-to-water pipeline system environment was used to represent the worst case environment, and could be used as a guide to estimate appropriate safety distance. Dynamic pressures obtained from the experimental measurement and simulation prediction mutually agreed along the high-pressure water jetting path. From the experimental and simulation exercises, zero effect distance for water-to-water medium was obtained at an estimated horizontal distance at a minimum of 1500 mm, while for the water-to-sand medium, the distance was estimated at a minimum of 1200 mm. - Highlights: • Safe separation distance of underground natural gas pipes was determined. • Pressure curve is inversely proportional to separation distance. • Water-to-water system represents the worst case environment. • Measured dynamic pressures mutually agreed with simulation results. • Safe separation distance of more than 1200 mm should be applied

Full Text Available Knowledge of petroleum leakage at oil refineries is vital for environmental study of water and soil pollution. Abadan Refinery is located between the Arvandrud and Bahmanshir rivers in the highly populated area of Abadan city. These rivers supply domestic, industrial, and agricultural water toAbadancity. During the war betweenIranandIraq, enormous volumes of oil and petroleum products leaked from storage tanks and pipelines at Abadan Refinery into the surrounding environment. The resulting pollution is a serious threat and a growing environmental concern for the region. In this work, twenty boreholes were dug to investigate petroleum leaks into the surrounding area both during and after the war. The thickness of petroleum floating on underground waters at the refinery was measured by sampling underground water over a period of one year along with measuring the piezometric heads of groundwater monitoring wells. Also, groundwater movement pattern at Abadan Refinery was determined by measuring the water table in each well over the same period. The results of sampling indicate that oil leaks were observed in just two wells; namely, wells No.3 and No.11. The results also show that the greatest portion of the oil spill in underground layers at Abadan Refinery was absorbed into clay soil.

Insufficient fluid velocity in petroleum pipelines can lead to the deposit of sand, corrosion products, and non-corrosion products on the pipe's metal surface, which in turn can lead to pitting corrosion. There is currently no reliable means of detecting and preventing the pitting process. This paper presented a computerized simulation tool that used the finite element method to model mass transfer-governed internal pitting corrosion under solids deposition in sour petroleum pipelines. The computational domain consisted of a hemispherical pit and a thin stagnant solution film under a surface deposit. The moving mesh method was used to track pitting growth. A Poisson equation was used to determine aqueous path migration of ions. Pitting corrosion rates were estimated using the Nernst-Planck equation. The model was used to predict the effects of different operating parameters on pitting corrosion rates. The model can be used to develop pigging and in-line-inspection (ILI) procedures. 35 refs., 2 tabs., 16 figs.

Recent reports place pipeline corrosion costs in North America at seven billion dollars per year. Pitting corrosion causes the higher percentage of failures among other corrosion mechanisms. This has motivated multiple modelling studies to be focused on corrosion pitting of underground pipelines. In this study, a continuous-time, non-homogenous pure birth Markov chain serves to model external pitting corrosion in buried pipelines. The analytical solution of Kolmogorov's forward equations for this type of Markov process gives the transition probability function in a discrete space of pit depths. The transition probability function can be completely identified by making a correlation between the stochastic pit depth mean and the deterministic mean obtained experimentally. The model proposed in this study can be applied to pitting corrosion data from repeated in-line pipeline inspections. Case studies presented in this work show how pipeline inspection and maintenance planning can be improved by using the proposed Markovian model for pitting corrosion.

This paper aims at assessing of the corrosion defects in standard petroleum pipelines by using shearography method. Shearography technique reveals the stress-affected zone due to additional loading which utilized the laser speckle correlation on the subject inspected. In this study, the artificial corroded pipeline is modeled by different of corrosion depth and width. The pressure was subjected into the 7 mm thickness pipe wall to form an internal air pressure as the loading mechanism. The study shows that change of internal pressure is very effective mechanism to reveal corrosion activity in the pipe. The speckle correlation for corrosion of more than 3 mm depth with ΔP≤0.24 MPa can clearly be observed. For comparison the Radiography Technique is used to correlate the depth, size and shape of the corrosion and finally the location of corrosion area. (Author)

Microbiologically influenced corrosion is a problem commonly encountered in facilities in the oil and gas industries. The present study describes bacterial enumeration and identification in diesel and naphtha pipelines located in the northwest and southwest region in India, using traditional cultivation technique and 16S rDNA gene sequencing. Phylogenetic analysis of 16S rRNA sequences of the isolates was carried out, and the samples obtained from the diesel and naphtha-transporting pipelines showed the occurrence of 11 bacterial species namely Serratia marcescens ACE2, Bacillus subtilis AR12, Bacillus cereus ACE4, Pseudomonas aeruginosa AI1, Klebsiella oxytoca ACP, Pseudomonas stutzeri AP2, Bacillus litoralis AN1, Bacillus sp., Bacillus pumilus AR2, Bacillus carboniphilus AR3, and Bacillus megaterium AR4. Sulfate-reducing bacteria were not detected in samples from both pipelines. The dominant bacterial species identified in the petroleum pipeline samples were B. cereus and S. marcescens in the diesel and naphtha pipelines, respectively. Therefore, several types of bacteria may be involved in biocorrosion arising from natural biofilms that develop in industrial facilities. In addition, localized (pitting) corrosion of the pipeline steel in the presence of the consortia was observed by scanning electron microscopy analysis. The potential role of each species in biofilm formation and steel corrosion is discussed. (orig.)

A continuous-time, non-homogenous linear growth (pure birth) Markov process has been used to model external pitting corrosion in underground pipelines. The closed form solution of Kolmogorov's forward equations for this type of Markov process is used to describe the transition probability function in a discrete pit depth space. The identification of the transition probability function can be achieved by correlating the stochastic pit depth mean with the deterministic mean obtained experimentally. Monte-Carlo simulations previously reported have been used to predict the time evolution of the mean value of the pit depth distribution for different soil textural classes. The simulated distributions have been used to create an empirical Markov chain-based stochastic model for predicting the evolution of pitting corrosion depth and rate distributions from the observed properties of the soil. The proposed model has also been applied to pitting corrosion data from pipeline repeated in-line inspections and laboratory immersion experiments.

2016-01-01

In this paper, a probabilistic methodology is presented for assessing the time-variant reliability of corroded underground pipelines subjected to space-variant soil aggressiveness. The Karhunen-Loève expansion is used to model the spatial variability of soil as a correlated stochastic field. The pipeline is considered as a series system for which the component and system failure probabilities are computed by Monte Carlo simulations. The probabilistic model provides a realistic time and space modelling of stochastic variations, leading to appropriate estimation of the lifetime distribution. The numerical analyses allow us to investigate the impact of various parameters on the reliability of underground pipelines, such as the soil aggressiveness, the pipe design variables, the soil correlation length and the pipeline length. The results show that neglecting the effect of spatial variability leads to pessimistic estimation of the residual lifetime and can lead to condemn prematurely the structure. - Highlights: • The role of soil heterogeneity in pipeline reliability assessment has been shown. • The impact of pipe length and soil correlation length has been examined. • The effect of the uncertainties related to design variables has been observed. • Pipe thickness design for homogeneous reliability has been proposed.

The detection of leaks on petroleum pipeline is a very important safety issue. Several studies were commissioned to develop new monitoring procedures for leakage detection. This paper sets out a new leak detection process. The approach developed took into consideration steady and transient states. The study investigated leak diagnosis problems in product pipelines using multi-sensor measurements (pressure, flux, density and temperature). The information collected from each sensor was considered as pieces of evidence that describe the operational conditions of the pipeline. The Dempster-Shafer (D-S) theory is used to associate multi-sensor data to pipe health indices. Experimental pressure and flow rate data were recorded using a Pipeline Leak Detection System (PLDS) acquisition card and used to verify the accuracy and reliability of this new detection method. The results showed that the degree of credibility was a high as 0.877. It was also found that multi-feature information fusion improves recognition of pipeline conditions.

This paper discusses the use of shearography as an alternative method of NDE for analysis of corrosion in petroleum pipeline. Shearography reveals direct information about defect induced stress which utilized the laser wave front pattern on the inspected object. In this study, the laser shearography technique was used to measure the derivative displacement of 7 mm thickness carbon steel pipe wall surface with simulated corrosion area at internal wall. The wave front pattern of internal wall corrosion in petroleum pipeline will be constructed to 3D image profiles in order to measure the severity and magnitude of material deformation. The process may involve of optical phase stepping procedure and the image processing algorithm for wrapped and unwrapped phase image at the deformation area. The unwrapped phase image can be meshed plot which finally lead to 3D image profiles. The phase stepping procedure in this analysis was selected by utilizing four phase stepping procedure using piezoelectric transducer (PZT) attached with optical mirror. (author)

Lifetime management of underground pipelines is mandatory for safe hydrocarbon transmission and distribution systems. Reliability analysis is recognized as a powerful decision-making tool for risk-based design and maintenance. Both the residual stresses generated during the manufacturing process and in-service corrosion reduce the ability to resist internal and external loading. In this study, the residual stress distribution in large diameter pipes has been characterized experimentally in order to be coupled with the corrosion model. During the pipe lifetime, residual stress relaxation occurs due to the loss of pipe thickness as material layers are consumed by corrosion. The reliability-based assessment of residual stress effects is applied to underground pipelines under a roadway, with and without active corrosion. It has been found that the residual stress greatly increases the failure probability, especially in the early stage of the pipe lifetime

It is established that the basis of information provision of normative documents is the method which includes the following main criteria: the value of the minimum current density of cathode protection; minimum security potential; maximum protective potential, minimal displacement of protective potential; strength criteria of pipe material; criteria of strength of phase layer between the metal and the coating; the strength of the metal in the defect of the insulation coating. It has been found out that the system "metal pipe - insulating dielectric coating" is characterized by such basic procedures as: identification of hazards; various variants of load asymmetry; evaluation of the boundary and optimal values of potentials and currents for the system of cathodic protection of the pipeline.

This paper presents a computational framework for implementing an advanced Monte Carlo simulation method, called Subset Simulation (SS) for time-dependent reliability prediction of underground flexible pipelines. The SS can provide better resolution for low failure probability level of rare failure events which are commonly encountered in pipeline engineering applications. Random samples of statistical variables are generated efficiently and used for computing probabilistic reliability model. It gains its efficiency by expressing a small probability event as a product of a sequence of intermediate events with larger conditional probabilities. The efficiency of SS has been demonstrated by numerical studies and attention in this work is devoted to scrutinise the robustness of the SS application in pipe reliability assessment and compared with direct Monte Carlo simulation (MCS) method. Reliability of a buried flexible steel pipe with time-dependent failure modes, namely, corrosion induced deflection, buckling, wall thrust and bending stress has been assessed in this study. The analysis indicates that corrosion induced excessive deflection is the most critical failure event whereas buckling is the least susceptible during the whole service life of the pipe. The study also shows that SS is robust method to estimate the reliability of buried pipelines and it is more efficient than MCS, especially in small failure probability prediction

Environmental contamination from leaking underground storage tanks poses a significant threat to human health and the environment. An estimated five to six million underground storage tanks containing hazardous substances or petroleum products are in use in the US. Originally placed underground as a fire prevention measure, these tanks have substantially reduced the damages from stored flammable liquids. However, an estimated 400,000 underground tanks are thought to be leaking now, and many more will begin to leak in the near future. Products released from these leaking tanks can threaten groundwater supplies, damage sewer lines and buried cables, poison crops, and lead to fires and explosions. As required by the Hazardous and Solid Waste Amendments (HSWA), the EPA has been developing a comprehensive regulatory program for underground storage tanks. The EPA proposed three sets of regulations pertaining to underground tanks. The first addressed technical requirements for petroleum and hazardous substance tanks, including new tank performance standards, release detection, release reporting and investigation, corrective action, and tank closure. The second proposed regulation addresses financial responsibility requirements for underground petroleum tanks. The third addressed standards for approval of state tank programs

Full Text Available In this paper the local materials used in concrete mix are studied in a manner that they can resist the aggressive marine environment and mechanical damage, which can occur at several stages during transportation, construction and installation of the pipelines. In earlier studies we succeeded in finding the Egyptian ilmenite ore adequate for concrete weight coating and already utilized for many pipeline projects in Egypt. According to the presence of about 30% titanium oxides in ilmenite composition which may be extracted to be used in others strategically fields, the object of this paper is to study and evaluate the mechanical, chemical and physical properties of another local hematite high density iron ore to be used in subsea concrete weight coating for offshore petroleum pipelines. The results indicate that the local material of Um Bogma hematite iron ore can substitute both imported iron ore and local ilmenite from Abu Ghalaga in this field to reduce the cost effective and increased economical value of local ores. Laboratory and field tests were conducted for the hematite ore forming a concrete mix, composed of hematite ore, cement and fresh water according to international concrete coating specification requirements, the ore produces a concrete mix with 190–195 pcf minimum dry density and compressive strength, after 28 days of hydration, varying from 40 to 45 N/mm2 (400–450 kg/cm2 which comply with the international standards and specifications of submarine petroleum pipeline coating. In addition, local hematite shows superior results than local ilmenite and achieves 190 pcf instead of 180 pcf in case of using ilmenite.

Full text: The stochastic nature of pitting corrosion has been recognized since the 1930s. It has been learned that this damage retains no memory of its past. Instead, the future state is determined only by the knowledge of its present state. This Markovian property that underlies the stochastic process governing pitting corrosion has been explored as a discrete Markovian process by many authors since the beginning of the 1990s for underground pipelines of the oil and gas industries and nuclear power plants. Corrosion is a genuine continuous time and space state Markovian process, so to model it as a discrete time and/or state space is an approximation to the problem. Markovian chains approaches, with an increasing number of states, could involve a large number of parameters, the transition rates between states, to be experimentally determined. Besides, such an increase in the number of states produces matrices with huge dimensions leading to time-consuming computational solutions. Recent approaches involving Markovian discrete process have overcome those difficulties but, on the other hand, a large number of soil and pipe stochastic variables have to be known. In this work we propose a continuous time and space state approach to the evolution of pit corrosion depths in underground pipelines. In order to illustrate the application of the model for defect depth growth a combination of real life data and Monte Carlo simulation was used. The process is described by a Fokker-Planck equation. The Fokker-Planck equation is completely determined by the knowledge of two functions known as the drift and diffusion coefficients. In this work we also show that those functions can be estimated from corrosion depth data from in-line inspections. Some particular forms of drift and diffusion coefficients lead to particular Fokker-Planck equations for which analytical solutions are known, as is the case for the Wiener process, the Ornstein-Uhlenbeck process and the Brownian motion

A non-homogenous, linear growth (pure birth) Markov process, with discrete states in continuous time, has been used to model external pitting corrosion in underground pipelines. The transition probability function for the pit depth is obtained from the analytical solution of the forward Kolmogorov equations for this process. The parameters of the transition probability function between depth states can be identified from the observed time evolution of the mean of the pit depth distribution. Monte Carlo simulations were used to predict the time evolution of the mean value of the pit depth distribution in soils with different physicochemical characteristics. The simulated distributions have been used to create an empirical Markov-chain-based stochastic model for predicting the evolution of pitting corrosion from the observed properties of the soil in contact with the pipeline. Real- life case studies, involving simulated and measured pit depth distributions are presented to illustrate the application of the proposed Markov chains model. (author)

Meric, Ilker; Johansen, Geir A.

2013-01-01

In the petroleum industry precipitation of scale onto the inner walls of hydrocarbon pipelines poses a significant challenge as, unless treated appropriately, deposits such as sulfate and carbonate scales reduce the overall flow area and even lead to blockage of entire sections of the pipework. This may in turn result in costly production suspension and maintenance work. Therefore, monitoring and characterization of scale deposits can be said to be of great importance. In this work, a preliminary feasibility study is carried out in order to investigate the possibility of utilizing photon scattering for scale detection in multiphase oil/water/gas pipelines.

The condition of underground constructions, communication and supply systems in the cities has to be periodically monitored and controlled in order to prevent their breakage, which can result in serious accident, especially in urban area. The most risk of damage have the underground construction made of steal such as pipelines widely used for water, gas and heat supply. To ensure the pipeline survivability it is necessary to carry out the operative and inexpensive control of pipelines condition. Induced electromagnetic methods of geophysics can be applied to provide such diagnostics. The highly developed surface in urbane area is one of cause hampering the realization of electromagnetic methods of diagnostics. The main problem is in finding of an appropriate place for the source line and electrodes on a limited surface area and their optimal position relative to the observation path to minimize their influence on observed data. Author made a number of experiments of an underground heating system pipeline diagnostics using different position of the source line and electrodes. The experiments were made on a 200 meters section over 2 meters deep pipeline. The admissible length of the source line and angle between the source line and the observation path were determined. The minimal length of the source line for the experiment conditions and accuracy made 30 meters, the maximum admissible angle departure from the perpendicular position made 30 degrees. The work was undertaken in cooperation with diagnostics company DIsSO, Saint-Petersburg, Russia.

The experimental study on the detection of grease stain for petroleum pipeline in Karamay oil-field of Xinjiang is carried out by gamma-ray transmission method. Experimental provision consists of sup 1 sup 3 sup 7 Cs gamma radiator and NaI(Tl) scintillation detector. The response of grease stain thickness of petroleum pipeline in Karamay oil-field is ln(N sub 0 /N)=0.00548 d-0.0046, and the response of paraffin thickness is ln(N sub 0 /N)=0.00522d-0.0126. The result of experiment indicates that the response of grease stain thickness is more sensitive than the response of paraffin thickness

Remediation of a 115,000-gallon petroleum pipeline leak

Noel, M.R.; Ebbott, K.A.

1992-01-01

A rupture in a buried petroleum pipeline in June, 1988 released 115,000 gallons of diesel fuel, contaminating soil and ground water at a site in Milwaukee, Wisconsin. Emergency and interim response actions resulted in the recovery of over 70,000 gallons of product from the ground surface, a nearby creek, and recovery trenches. Based on the results of a contamination assessment, the most cost effective and technically feasible remedial alternative included low temperature thermal desorption for treatment of the impacted soils, and recovery of impacted ground water with discharge to a sanitary sewer. The implementation of the thermal desorption process was the first application of its type in the State of Wisconsin. Approximately 10,000 cubic yards of soil, with a total petroleum hydrocarbon (TPH) concentration of up to 24,000 parts per million (ppm), was treated at the site using the thermal desorption system. Using a feed rate of approximately 20 tons per hour, the impacted unconsolidated materials, varying in composition from gravelly sand to silty clay, were heated to 400 to 500 degrees F in a propane-fired rotary kiln. In the process, petroleum was vaporized off the soils and then completely oxidized at 1450 degrees F in an afterburner. After processing, the soil was replaced in the excavation with a TPH concentration of less than 10 ppm. Impacted ground water is still being treated at the site using a 225-foot long interception trench. An automated pumping system recovers slightly impacted ground water which is subsequently discharged to the sanitary sewer. Residual free product is collected from the water surface manually using oil skimming devices. Dissolved volatile organic compounds (VOCs) total less than 5 ppm; therefore no treatment is required prior to discharge to the sewer. Pending approval of a permit application, discharge will be to a nearby stream

Airborne pipeline leak detection: UV or IR?

Science.gov (United States)

Babin, François; Gravel, Jean-François; Allard, Martin

2016-05-01

This paper presents a study of different approaches to the measurement of the above ground vapor plume created by the spill caused by a small 0.1 l/min (or less) leak in an underground liquid petroleum pipeline. The scenarios are those for the measurement from an airborne platform. The usual approach is that of IR absorption, but in the case of liquid petroleum products, there are drawbacks that will be discussed, especially when using alkanes to detect a leak. The optical measurements studied include UV enhanced Raman lidar, UV fluorescence lidar and IR absorption path integrated lidars. The breadboards used for testing the different approaches will be described along with the set-ups for leak simulation. Although IR absorption would intuitively be the most sensitive, it is shown that UV-Raman could be an alternative. When using the very broad alkane signature in the IR, the varying ground spectral reflectance are a problem. It is also determined that integrated path measurements are preferred, the UV enhanced Raman measurements showing that the vapor plume stays very close to the ground.

An integrated multi−period planning of the production and transportation of multiple petroleum products in a single pipeline system

Directory of Open Access Journals (Sweden)

Alberto Herrán

2011-01-01

Full Text Available A multiproduct pipeline provides an economic way to transport large volumes of refined petroleum products over long distances. In such a pipeline, different products are pumped back−to−back without any separation device between them. The sequence and lengths of such pumping runs must be carefully selected in order to meet market demands while minimizing pipeline operational costs and satisfying several constraints. The production planning and scheduling of the products at the refinery must also be synchronized with the transportation in order to avoid the usage of the system at some peak−hour time intervals. In this paper, we propose a multi−period mixed integer nonlinear programming (MINLP model for an optimal planning and scheduling of the production and transportation of multiple petroleum products from a refinery plant connected to several depots through a single pipeline system. The objective of this work is to generalize the mixed integer linear programming (MILP formulation proposed by Cafaro and Cerdá (2004, Computers and Chemical Engineering where only a single planning period was considered and the production planning and scheduling was not part of the decision process. Numerical examples show how the use of a single period model for a given time period may lead to infeasible solutions when it is used for the upcoming periods. These examples also show how integrating production planning with the transportation and the use of a multi−period model may result in a cost saving compared to using a single−period model for each period, independently.

Study on the petroleum recovery technology : Analysis of pipeline flow

1998-12-01

The petroleum exploration activities have been performed by our own technology in the concession Block VI-I in Korean continental shelf for more than 10 years. Gas and gas condensate were discovered from several exploratory wells drilled in this block. This year, the news of another hit in the well of Gorae-V was very encouraging. Different from the previous gas discoveries, the reservoir properties and the productivity of Gorea-V well were excellent and the reserve estimate was very optimistic for the gas field development in this region. Gas consumption was very rapidly increased during recent years because of the image of cleaner fuel compared with other fossil fuels and convenience of usage. Korea is the fifth country in the world in terms of total quantity of petroleum consumption. This is the reason why the secure supply of oil and gas in the future is vital to our industry. The development of gas or gas condensate reservoir is different from that of oil reservoir. Especially sales contract must be made before the initiation of gas field exploitation. The production facilities including pipeline system must be selected and designed for further consideration. In this study, we have selected the 'K' offshore gas field where the water depth is 155 m and the distance from the shore is 50 km. The main purpose of this production system analysis is to select the optimum size and capacity of production facilities including pipeline in order to find the most appropriate production schedule. Production system analysis using nodal analysis includes deliverability calculation of the reservoir, production system optimization, recoverable reserve estimation, and performance forecast of the reservoir with three different production rate scenarios. The reservoir pressure is 4525 psia and the temperature is 248 deg.F. The OGIP of this reservoir was calculated as 24.64 BCF/well and the reservoir is expected to produce for up to 10 years. The porosity is 6% and the

The objective of this study was to locate the leakage point(s) in an underground cooling water pipeline of a Thermal Power Station for pre-shutdown planning purposes. The internal diameter of the pipeline was 2240 mm with 12 mm with 12 (mild steel) wall thickness and it was buried under 1.0 meter reinforced concrete and 0.5-1.0 meter soil/sand cover. The volume flow rate of the pipeline was 29043 m/sup 3/hour at 2kg/cm/sup 2/ pressure. The linear speed of water flowing inside the pipeline was around 2 m/sec. This gave rise to a very high volume fast moving system. Radiotracer technique was used to investigate the problem under investigation. About 50 mCi of /sup 131/I radiotracer, in the form of NaI solution, was injected into the system and radiotracer evolution near suspected leakage point(s) was monitored using radiation detectors (NaI, 2 x 2 inch crystal size). Seven detectors were installed around three teeing off pipes (leakage area) inside the plant building and one at the injection point near the pump outlet. On line data acquisition system was used to acquire the radiotracer data. The leakage water was exiting from the floor just along the pipes carrying main flow of water. The time lag between the arrival, at detectors, of radiotracer flowing inside the pipeline and that present in the leakage water (outside the pipeline) was exploited to identify the position of leakage. The tracer test revealed that there was leakage at two points. The leakage at one point was small as compared at the other points. (author)

Numerical Investigation of the Thermal Regime of Underground Channel Heat Pipelines Under Flooding Conditions with the Use of a Conductive-Convective Heat Transfer Model

Science.gov (United States)

Polovnikov, V. Yu.

2018-05-01

This paper presents the results of numerical analysis of thermal regimes and heat losses of underground channel heating systems under flooding conditions with the use of a convective-conductive heat transfer model with the example of the configuration of the heat pipeline widely used in the Russian Federation — a nonpassage ferroconcrete channel (crawlway) and pipelines insulated with mineral wool and a protective covering layer. It has been shown that convective motion of water in the channel cavity of the heat pipeline under flooding conditions has no marked effect on the intensification of heat losses. It has been established that for the case under consideration, heat losses of the heat pipeline under flooding conditions increase from 0.75 to 52.39% due to the sharp increase in the effective thermal characteristics of the covering layer and the heat insulator caused by their moistening.

2003-07-01

Liquid pipeline codes generally stipulate placement of block valves along liquid transmission pipelines such as on each side of major river crossings where environmental hazards could cause or are foreseen to potentially cause serious consequences. Codes, however, do not stipulate any requirement for block valve spacing for low vapour pressure petroleum transportation, nor for remote pipeline valve operations to reduce spills. A review of pipeline codes for valve requirement and spill limitation in high consequence areas is thus presented along with a criteria for an acceptable spill volume that could be caused by pipeline leak/full rupture. A technique for deciding economically and technically effective pipeline block valve automation for remote operation to reduce oil spilled and control of hazards is also provided. In this review, industry practice is highlighted and application of the criteria for maximum permissible oil spill and the technique for deciding valve automation thus developed, as applied to ORSUB pipeline is presented. ORSUB is one of the three initially selected pipelines that have been studied. These pipelines represent about 14% of the total length of petroleum transmission lines operated by PETROBRAS Transporte S.A. (TRANSPETRO) in Brazil. Based on the implementation of valve motorization on these three pipeline, motorization of block valves for remote operation on the remaining pipelines is intended, depending on the success of these implementations, on historical records of failure and appropriate ranking.

Pollution from pipelines

International Nuclear Information System (INIS)

1991-01-01

During the 1980s, over 3,900 spills from land-based pipelines released nearly 20 million gallons of oil into U.S. waters-almost twice as much as was released by the March 1989 Exxon Valdez oil spill. Although the Department of Transportation is responsible for preventing water pollution from petroleum pipelines, GAO found that it has not established a program to prevent such pollution. DOT has instead delegated this responsibility to the Coast Guard, which has a program to stop water pollution from ships, but not from pipelines. This paper reports that, in the absence of any federal program to prevent water pollution from pipelines, both the Coast Guard and the Environmental Protection Agency have taken steps to plan for and respond to oil spills, including those from pipelines, as required by the Clean Water Act. The Coast Guard cannot, however, adequately plan for or ensure a timely response to pipeline spills because it generally is unaware of specific locations and operators of pipelines

Use of absorption spectroscopy for refined petroleum product discrimination

Science.gov (United States)

Short, Michael

1991-07-01

On-line discrimination between arbitrary petroleum products is necessary for optimal control of petroleum refinery and pipeline operation and process control involving petroleum distillates. There are a number of techniques by which petroleum products can be distinguished from one another. Among these, optical measurements offer fast, non-intrusive, real-time characterization. The application examined here involves optically monitoring the interface between dissimilar batches of fluids in a gasoline pipeline. After examination of near- infrared and mid-infrared absorption spectroscopy and Raman spectroscopy, Fourier transform mid-infrared (FTIR) spectroscopy was chosen as the best candidate for implementation. On- line FTIR data is presented, verifying the applicability of the technique for batch interface detection.

Since 2006, the petroleum industry has been interested in collaboration to determine labour demand and supply/demand gaps for the upstream petroleum industry. In 2006, the petroleum industry experienced strong employment growth and was having difficulty finding workers. Comprehensive, up-to-date labour market information and analysis are the key foundation for addressing labour supply/demand issues. This document presented labour market information on the petroleum industry in order to inform company retention and recruitment offices; government departments involved in development of labour market policies and programs; education and training institutions; guidance counsellors, employment centres and organizations that work with youth and labour supply pools; and job seekers. Specific topics that were discussed included two industry scenarios (growth and base case) in determining the petroleum industry's medium-and long-term employment needs; labour supply/demand considerations for the industry as a whole and an industry-wide cost management; and an analysis of exploration and production, oil sands, services, and pipeline sectors to 2020. It was concluded that while new employment is not expected to lead to labour shortages within the pipeline sector, attrition due to requirements almost certainly would. In the growth scenario, it is likely the pipeline sector will be challenged by competition from the other petroleum industry sectors. tabs., figs., appendices.

When faced with a potentially very expensive environmental cleanup, most companies and individuals try to do the only sensible thing, which is to find out if anyone else will pay the bill. This presentation will outline two avenues that may provide a substantial financial contribution to environmental cleanups: (a) California's Underground Storage Tank Cleanup Fund and (b) insurance policies. The Underground Storage Tank Cleanup Fund was established in 1989 to help eligible owners and operators of petroleum underground storage tanks (USTs) to: (a) get reimbursed for costs of unauthorized releases of petroleum from USTs; (b) get reimbursed for damages awarded to third parties as a result of unauthorized releases of petroleum from USTs; and (c) meet federal and state requirements that the UST owner and/or operator be able to pay for cleanup costs and damages to third parties caused by unauthorized releases of petroleum

Cathode protection for underground steel tanks

Cathodic protection of underground petroleum storage tanks and piping systems is acceptable for both economic and ecological reasons. With out the cathodic protection of underground steel reservoirs, short time after the exploitation, there was a bore as a result of underground corrosion. The bore causes ecological consequences and at the same time its repair needs big investments. Furthermore, there are great number of tanks placed near cities, so in the future this problem needs a special attention in order to preserve ecological surrounding. The topic of this paper is underground corrosion as well as cathodic protection of steel tanks for oil derivatives storage. (author)

The Hanford Site includes 149 single-shell tanks, organized in 12 'tank farms,' with contents managed as high-level mixed waste. The Hanford Federal Facility Agreement and Consent Order requires that one tank farm, the Waste Management Area C, be closed by June 30, 2019. A challenge to this project is the disposition and closure of Waste Management Area C underground pipelines. Waste Management Area C contains nearly seven miles of pipelines and 200 separate pipe segments. The pipelines were taken out of service decades ago and contain unknown volumes and concentrations of tank waste residuals from past operations. To understand the scope of activities that may be required for these pipelines, an evaluation was performed. The purpose of the evaluation was to identify what, if any, characterization methods and/or closure actions may be implemented at Waste Management Area C for closure of Waste Management Area C by 2019. Physical and analytical data do not exist for Waste Management Area C pipeline waste residuals. To develop estimates of residual volumes and inventories of contamination, an extensive search of available information on pipelines was conducted. The search included evaluating historical operation and occurrence records, physical attributes, schematics and drawings, and contaminant inventories associated with the process history of plutonium separations facilities and waste separations and stabilization operations. Scoping analyses of impacts to human health and the environment using three separate methodologies were then developed based on the waste residual estimates. All analyses resulted in preliminary assessments, indicating that pipeline waste residuals presented a comparably low long-term impact to groundwater with respect to soil, tank and other ancillary equipment residuals, but exceeded Washington State cleanup requirement values. In addition to performing the impact analyses, the assessment evaluated available sampling technologies

Petroleum product scarcity: a review of the supply and distribution of petroleum products in Nigeria

International Nuclear Information System (INIS)

Akpoghomeh, Osi S.; Badejo, Dele

2006-01-01

Nigeria ranks high among the comity of oil producers both at the world level and among the OPEC eleven. It is, therefore, paradoxical that the supply of all petroleum products is erratic and has declined sharply in the recent past. This paper thus reviews the petroleum product supply and distribution systems in the country to ascertain the extent to which the system may have contributed to the present product scarcity in Nigeria and, by extension, identify the causes of the present regime of petroleum product scarcity. The paper observes that the network density and connectivity of petroleum product distribution pipelines are low and both indicators consequently show the inadequacy/deficiency of the network in ensuring an efficient distribution system. The supply mode, on the other hand, has, over the years, demonstrated its inability to guarantee adequate supply due to factors including sabotage, vandalism, banditry and poorly maintained infrastructure. Further, the federal government and the major and independent marketers could not sustain the importation of petroleum products because of the shortfall between the landed cost of imported products and their selling prices in Nigeria, which made the business unprofitable. Finally, the paper examines the withdrawal by the federal government of subsidies on the price of petroleum products consumed locally. All the above factors together occasioned increases in the cost of products. In conclusion, this paper supports the call for the privatization of refineries and the depot/pipeline system as a viable option to end the supply problems. (Author)

Full Text Available In underground mining of solid minerals becoming increasingly common development system with stowing hardening mixtures. In this case the natural ore array after it is replaced by an artificial excavation of solidified filling mixture consisting of binder, aggregates and water. Such a mixture is prepared on the surface on special stowing complexes and transported underground at special stowing pipelines. However, it is transported to the horizons of a few kilometers, which requires a sustainable mode of motion of such a mixture in the pipeline. Hardening stowing mixture changes its rheological characteristics over time, which complicates the calculation of the parameters of pipeline transportation. The article suggests a method of determining the initial parameters of such mixtures: the status coefficient, indicator of transportability, coefficient of hydrodynamic resistance to motion of the mixture. These indicators characterize the mixture in terms of the possibility to transport it through pipes. On the basis of these indicators is proposed methodology for calculating the parameters of pipeline transport hardening filling mixtures in drift mode when traffic on the horizontal part of the mixture under pressure column of the mixture in the vertical part of the backfill of the pipeline. This technique allows stable operation is guaranteed to provide pipeline transportation.

A clustering based method to evaluate soil corrosivity for pipeline external integrity management

International Nuclear Information System (INIS)

Yajima, Ayako; Wang, Hui; Liang, Robert Y.; Castaneda, Homero

2015-01-01

One important category of transportation infrastructure is underground pipelines. Corrosion of these buried pipeline systems may cause pipeline failures with the attendant hazards of property loss and fatalities. Therefore, developing the capability to estimate the soil corrosivity is important for designing and preserving materials and for risk assessment. The deterioration rate of metal is highly influenced by the physicochemical characteristics of a material and the environment of its surroundings. In this study, the field data obtained from the southeast region of Mexico was examined using various data mining techniques to determine the usefulness of these techniques for clustering soil corrosivity level. Specifically, the soil was classified into different corrosivity level clusters by k-means and Gaussian mixture model (GMM). In terms of physical space, GMM shows better separability; therefore, the distributions of the material loss of the buried petroleum pipeline walls were estimated via the empirical density within GMM clusters. The soil corrosivity levels of the clusters were determined based on the medians of metal loss. The proposed clustering method was demonstrated to be capable of classifying the soil into different levels of corrosivity severity. - Highlights: • The clustering approach is applied to the data extracted from a real-life pipeline system. • Soil properties in the right-of-way are analyzed via clustering techniques to assess corrosivity. • GMM is selected as the preferred method for detecting the hidden pattern of in-situ data. • K–W test is performed for significant difference of corrosivity level between clusters

A petroleum contaminated soil bioremediation facility

The amount of petroleum contaminated soil (PCS) at the Savannah River site (SRS) that has been identified, excavated and is currently in storage has increased several fold during the last few years. Several factors have contributed to this problem: (1) South Carolina Department of Health ad Environmental control (SCDHEC) lowered the sanitary landfill maximum concentration for total petroleum hydrocarbons (TPH) in the soil from 500 to 100 parts per million (ppm), (2) removal and replacement of underground storage tanks at several sites, (3) most recently SCDHEC disallowed aeration for treatment of contaminated soil, and (4) discovery of several very large contaminated areas of soil associated with leaking underground storage tanks (LUST), leaking pipes, disposal areas, and spills. Thus, SRS has an urgent need to remediate large quantities of contaminated soil that are currently stockpiled and the anticipated contaminated soils to be generated from accidental spills. As long as we utilize petroleum based compounds at the site, we will continue to generate contaminated soil that will require remediation.

This paper reports that a significant quantity of oil is left in reservoirs after conventional oil recovery techniques have been applied. In West Virginia and Pennsylvania alone, this oil has been estimated at over 4.5 billion barrels (0.72 billion m 3 ). Conventional recovery methods are already being used when applicable. But a new recovery method is needed for use in reservoirs that have been abandoned. One alternative method for recovery of the residual oil is known as oil recovery from underground drill sites. This recovery technology is a combination of proven methods and equipment from the petroleum, mining, and civil construction industries. Underground oil recovery can be an economically viable method of producing oil. This has been shown in producing fields, field tests, and feasibility, studies. Faced with decreasing domestic oil production, the petroleum industry should give serious consideration to the use of oil recovery from underground drill sites as a safe, practical, and environmentally sensitive alternative method of producing oil from many reservoirs

Grover, D D

1979-01-01

Pipelines are the leading bulk commodity transporter and should play an even more important role in the future of energy transportation and distribution. As fossil fuel and low-cost uranium resources become depleted, it will be economical to produce hydrogen by electrolysis and transport it through underground pipelines to points of consumption. The cost would be only two to three times that of transporting natural gas per unit of heat energy and substantially less than the cost of transporting electric energy in overhead, extra-high-voltage transmission lines. Pipeline design, including economic pipe diameter; pipe material; operation by remote control and automation; cathodic protection; pipeline construction; and pipeline maintenance, particularly as regards the 1157 km long Oil India Pipeline, are discussed.

Underground storage tanks cause environmental chaos

This paper reports that during the 1950s and the subsequent three decades, petroleum products were stored in single-walled steel underground tanks; an out-of-sight, out-of-mind philosophy prevailed. Unfathomable amounts of toxic petroleum products leaking into the nation's ground water supplies has prompted enactment of recent and much needed legislation and regulation to remedy this major problem. Is the public aware of this serious ecological imbroglio? No, not as yet; except for the closing of many rural service stations and the plethora of dug-up, exposed tanks at urban stations, one could never imagine the severity of this debacle confronting the petroleum industry and the nation's environment

Leak Detection in Heat Exchangers and Underground Pipelines Using Radiotracers. Material for Education and On-The-Job Training for Practitioners of Radiotracer Technology

International Nuclear Information System (INIS)

2009-01-01

The International Atomic Energy Agency plays a major role in facilitating the transfer of radiotracer technology to developing Member States. The use of radiotracer techniques is well established in many Member States; some hundred radiotracer and end user specialists have been trained in radiotracer techniques and their applications; nearly 50 radiotracer laboratories have been working in this field. The training of radiotracer practitioners is vital for the provision of quality services to industry. Leak detection using radiotracer techniques is probably one of the most widespread applications of radiotracers in industrial troubleshooting. Radiotracer techniques are the most competitive for online leak inspection of heat exchangers and buried pipelines. Radiotracers help in early detection of leaks in heat exchangers and underground transporting pipelines, thus saving money, reducing shutdown time, ensuring safe operation and protecting the environment from pollution. The training course series on leak detection in heat exchangers and underground pipelines using radiotracers addresses the needs of the radiotracer groups and their end users. Besides training purposes, this material will assist radiotracer groups in establishing their quality control and accreditation systems. This training course material is based on lecture notes and practical work delivered by many experts in IAEA-supported activities. In particular, the Technical Cooperation Projects implemented under the Regional Cooperative Agreement (RCA) of the IAEA Member States in the Asia and the Pacific Region have been successful in transferring and implementing radiotracer techniques for leak detection to many end users from oil and gas production, oil refineries and the petrochemical industry. The experience obtained in the RCA Region is presented in the training material illustrated with many case studies carried out in several RCA Member States. Lectures and case studies were reviewed by a number

The transportation of petroleum products and other chemicals can involve spillage and leaks despite being closely controlled. Human error in the loading of road tankers or consumers refuelling their vehicles at service stations can lead to spillage accidents. Seepage through permeable concrete and its expansion joints can occur for diesel underground tanks with serious environmental consequences. This article describes methods which could be adopted by the petroleum industry to prevent these accidental incidents from causing environmental pollution. Service station forecourts could be constructed, using precast concrete hexagonal blocks with dry sand between them and then have a coating of sealant to prevent spills from seeping into ground water. Secondary containment for underground tanks should be given an elastomeric membrane coating. (UK)

Environmental assessment of the brine pipeline replacement for the Strategic Petroleum Reserve Bryan Mound Facility in Brazoria County, Texas

Energy Technology Data Exchange (ETDEWEB)

1993-09-01

The Department of Energy (DOE) has prepared an environmental assessment (EA), DOE/EA-0804, for the proposed replacement of a deteriorated brine disposal pipeline from the Strategic Petroleum Reserve (SPR) Bryan Mound storage facility in Brazoria County, Texas, into the Gulf of Mexico. In addition, the ocean discharge outfall would be moved shoreward by locating the brine diffuser at the end of the pipeline 3.5 miles offshore at a minimum depth of 30 feet. The action would occur in a floodplain and wetlands; therefore, a floodplain/wetlands assessment has been prepared in conjunction with this EA. Based on the analyses in the EA, DOE has determined that the proposed action is not a major Federal action significantly affecting the quality of the human environment within the meaning of the National Environmental Policy Act (NEPA) of 1969 (42 USC. 4321, et seg.). Therefore, the preparation of an Environmental Impact Statement (EIS) is not required, and the Department is issuing this Finding of No Significant Impact (FONSI). This FONSI also includes a Floodplain Statement of Findings in accordance with 10 CFR Part 1022.

Pipeline are known as the most reliable and economical mode of transportation for petroleum and its derivatives, especially when large amounts of products have to be pumped for large distances. In this work we address the short-term schedule of a pipeline system comprising the distribution of several petroleum derivatives from a single oil refinery to several depots, connected to local consumer markets, through a single multi-product pipeline. We propose an integer linear programming formulation and a variable neighborhood search meta-heuristic in order to compare the performances of the exact and heuristic approaches to the problem. Computational tests in C language and MOSEL/XPRESS-MP language are performed over a real Brazilian pipeline system. (author)

The transport of materials in pipelines is continuously increasing worldwide. Pipelines are one of the most economic and safe transport systems in all directions. In order to ensure this, not only new pipelines but also existing pipelines have to be kept up to date technically. Leakages are a possible safety risk. Leaks are manifold and range from earth quakes, corrosion or material fatigue up to open-up by drilling by thieves. A specific leakage detection often is used in order to limit the risks. The minimization of the consequences of accidents, downtimes and product losses as well as regulatory procedures is the reason for the detection of leakages. Leaks in pipelines can be detected on different kinds - from a simple visual inspection during the inspection up to computer-assisted systems monitoring certain states also in underground and submarine pipeline.

Pipeline Drag Reducers

Marawan, H.

2004-01-01

Pipeline drag reducers have proven to be an extremely powerful tool in fluid transportation. High molecular weight polymers are used to reduce the frictional pressure loss ratio in crude oil pipelines, refined fuel and aqueous pipelines. Chemical structure of the main used pipeline drag reducers is one of the following polymers and copolymers classified according to the type of fluid to ; low density polyethylene, copolymer of I-hexane cross linked with divinyl benzene, polyacrylamide, polyalkylene oxide polymers and their copolymers, fluorocarbons, polyalkyl methacrylates and terpolymer of styrene, alkyl acrylate and acrylic acid. Drag reduction is the increase in pump ability of a fluid caused by the addition of small amounts of an additive to the fluid. The effectiveness of a drag reducer is normally expressed in terms of percent drag reduction. Frictional pressure loss in a pipeline system is a waste of energy and it costly. The drag reducing additive minimizes the flow turbulence, increases throughput and reduces the energy costs. The Flow can be increased by more than 80 % with existing assets. The effectiveness of the injected drag reducer in Mostorod to Tanta crude oil pipeline achieved 35.4 % drag reduction and 23.2 % flow increase of the actual performance The experimental application of DRA on Arab Petroleum Pipeline Company (Summed) achieved a flow increase ranging from 9-32 %

Gathering pipeline methane emissions in Fayetteville shale pipelines and scoping guidelines for future pipeline measurement campaigns

Directory of Open Access Journals (Sweden)

Daniel J. Zimmerle

2017-11-01

Full Text Available Gathering pipelines, which transport gas from well pads to downstream processing, are a sector of the natural gas supply chain for which little measured methane emissions data are available. This study performed leak detection and measurement on 96 km of gathering pipeline and the associated 56 pigging facilities and 39 block valves. The study found one underground leak accounting for 83% (4.0 kg CH4/hr of total measured emissions. Methane emissions for the 4684 km of gathering pipeline in the study area were estimated at 402 kg CH4/hr [95 to 1065 kg CH4/hr, 95% CI], or 1% [0.2% to 2.6%] of all methane emissions measured during a prior aircraft study of the same area. Emissions estimated by this study fall within the uncertainty range of emissions estimated using emission factors from EPA’s 2015 Greenhouse Inventory and study activity estimates. While EPA’s current inventory is based upon emission factors from distribution mains measured in the 1990s, this study indicates that using emission factors from more recent distribution studies could significantly underestimate emissions from gathering pipelines. To guide broader studies of pipeline emissions, we also estimate the fraction of the pipeline length within a basin that must be measured to constrain uncertainty of pipeline emissions estimates to within 1% of total basin emissions. The study provides both substantial insight into the mix of emission sources and guidance for future gathering pipeline studies, but since measurements were made in a single basin, the results are not sufficiently representative to provide methane emission factors at the regional or national level.

Crude oil pipeline expansion summary

International Nuclear Information System (INIS)

2005-02-01

The Canadian Association of Petroleum Producers has been working with producers to address issues associated with the development of new pipeline capacity from western Canada. This document presents an assessment of the need for additional oil pipeline capacity given the changing mix of crude oil types and forecasted supply growth. It is of particular interest to crude oil producers and contributes to current available information for market participants. While detailed, the underlying analysis does not account for all the factors that may come into play when individual market participants make choices about which expansions they may support. The key focus is on the importance of timely expansion. It was emphasized that if pipeline expansions lags the crude supply growth, then the consequences would be both significant and unacceptable. Obstacles to timely expansion are also discussed. The report reviews the production and supply forecasts, the existing crude oil pipeline infrastructure, opportunities for new market development, requirements for new pipeline capacity and tolling options for pipeline development. tabs., figs., 1 appendix

Planning and scheduling of the pipeline network operations aim the most efficient use of the resources resulting in a better performance of the network. A petroleum distribution pipeline network is composed by refineries, sources and/or storage parks, connected by a set of pipelines, which operate the transportation of petroleum and derivatives among adjacent areas. In real scenes, this problem is considered a combinatorial problem, which has difficult solution, which makes necessary methodologies of the resolution that present low computational time. This work aims to get solutions that attempt the demands and minimize the number of batch fragmentations on the sent operations of products for the pipelines in a simplified model of a real network, through by application of the local search metaheuristic GRASP. GRASP does not depend of solutions of previous iterations and works in a random way so it allows the search for the solution in an ampler and diversified search space. GRASP utilization does not demand complex calculation, even the construction stage that requires more computational effort, which provides relative rapidity in the attainment of good solutions. GRASP application on the scheduling of the operations of this network presented feasible solutions in a low computational time. (author)

It is therefore necessary that the flow diagrams of a plant are clearly understandable and in accordance with the technical rules even in the early stages of planning. This book concentrates on steel pipeline which are not laid underground but of the type used mostly in industrial applications. The pictures and equations provided can be used for the design of pipelines, tables and diagrams are given to facilitate estimation of elasticity, pipeline pressure losses and insulating thicknesses. An overview of the equations is given at the end of the book. Many examples facilitate learning. (orig.) [de

A new segmentation strategy for processing magnetic anomaly detection data of shallow depth ferromagnetic pipeline

Science.gov (United States)

Feng, Shuo; Liu, Dejun; Cheng, Xing; Fang, Huafeng; Li, Caifang

2017-04-01

Magnetic anomalies produced by underground ferromagnetic pipelines because of the polarization of earth's magnetic field are used to obtain the information on the location, buried depth and other parameters of pipelines. In order to achieve a fast inversion and interpretation of measured data, it is necessary to develop a fast and stable forward method. Magnetic dipole reconstruction (MDR), as a kind of integration numerical method, is well suited for simulating a thin pipeline anomaly. In MDR the pipeline model must be cut into small magnetic dipoles through different segmentation methods. The segmentation method has an impact on the stability and speed of forward calculation. Rapid and accurate simulation of deep-buried pipelines has been achieved by exciting segmentation method. However, in practical measurement, the depth of underground pipe is uncertain. When it comes to the shallow-buried pipeline, the present segmentation may generate significant errors. This paper aims at solving this problem in three stages. First, the cause of inaccuracy is analyzed by simulation experiment. Secondly, new variable interval section segmentation is proposed based on the existing segmentation. It can help MDR method to obtain simulation results in a fast way under the premise of ensuring the accuracy of different depth models. Finally, the measured data is inversed based on new segmentation method. The result proves that the inversion based on the new segmentation can achieve fast and accurate inversion of depth parameters of underground pipes without being limited by pipeline depth.

Evaluation of underground pipe-structure interface for surface impact load

Wang, Shen, E-mail: swang@terrapower.com

2017-06-15

1997-01-01

Petroleum and natural gas resources, industry organization, production, pipeline construction and other transportation issues, refining and business aspects of the Chinese petroleum and natural gas industries were reviewed. The need for large amounts of foreign capital and western technology to stem the deficit in domestic hydrocarbon supply were emphasized as being responsible for the creation in China of favourable conditions for foreign participation in oil and gas exploration, and for the growing confidence for Western investment in China. The most important considerations for successful participation in the economic development of China include: understanding the roles of networking, cultural affinity and reciprocity; hands-on management; finding an appropriate business partner, agent/distributor, or joint venture partner; and understanding local peculiarities and customs. 3 refs

Nardecchia, Fabio; Gugliermetti, Luca; Gugliermetti, Franco

2017-07-01

Underground pipelines are built all over the world and the knowledge of their thermal interaction with the soil is crucial for their design. This paper studies the "thermal influenced zone" produced by a buried pipeline and the parameters that can influence its extension by 2D-steady state CFD simulations with the aim to improve the design of new pipelines in permafrost. In order to represent a real case, the study is referred to the Eastern Siberia-Pacific Ocean Oil Pipeline at the three stations of Mo'he, Jiagedaqi and Qiqi'har. Different burial depth sand diameters of the pipe are analyzed; the simulation results show that the effect of the oil pipeline diameter on the thermal field increases with the increase of the distance from the starting station.

The transport of liquid or gas fluids, such as water, fuel, chemical products, minerals, among others, through underground pipelines, is becoming more significant in the whole world, specially in Brazil, due to low cost, operational security and low physical interference at the surface. By the other hand, the ambient matters, the population's security in pipeline tracing and economic aspects lead to greater requirements in relation to the integrity of those installations. Corrosion is one of the most important causes of underground pipelines' deterioration and coating and cathodic protection are recommended to prevent it from occurring. However, both techniques must be considered in the pipeline project for it to be successful. At the present work the most important kinds of coating for underground pipelines are presented, as well as the applications, limitations, reference norms and the interface with the cathodic protection systems in relation to the efficiencies to be adopted and the expected performance. Is it also discussed the welded piping joints confection and the protection difficulties when the efficiencies are not corresponded to those foreseen in the cathodic protection systems project.

Pipelines are known as the most reliable and economical mode of transportation for petroleum and its derivatives, especially when large amounts of products have to be pumped for large distances. We address the short-term schedule of a pipeline system comprising the distribution of several petroleum derivatives from a single oil refinery to several depots, connected to local consumer markets, through a single multi-product pipeline. The major difficulties faced in these operations are related to the satisfaction of product demands by the various consumer markets, and operational constraints such as the maximum sizes of contiguous pumping packs, and the immiscible products. Several researchers have developed models and techniques for this short-term pipeline scheduling problem. Two different methodologies have been proposed in the literature: heuristic search techniques and exact methods. In this paper, we use a branch-and cut algorithm, performed in Xpress-MP{sup T}M, and compare the solutions obtained with that ones obtained before using the Variable Neighborhood Search metaheuristic. The computational results showed a significant improvement of performance in relation to previous algorithm. (author)

Expansion of the Strategic Petroleum Reserve, Alabama, Louisiana, Mississippi, and Texas: Draft Environmental Impact Statement

International Nuclear Information System (INIS)

1992-10-01

The proposed action entails the development of a plan for 250 million barrels of new crude oil storage capacity in two Gulf Coast salt domes to expand the Strategic Petroleum Reserve pursuant to Congressional directive (PL 101--383 and PL 101--512). Storage capacity would be developed by solution-mining the salt which would require about two billion barrels of surface water and would generate about two billion barrels of salt brine. The brine would be disposed of primarily by ocean discharge and alternatively by deep underground injection. Crude oil fill and distribution systems would require new pipelines and terminal facilities. This EIS assesses the impacts of construction and operation for the range of alternatives being considered and focuses on oil and brine spill risk and impacts of brine disposal, water and land use, groundwater contamination, hydrocarbon emissions, and involvement with wetlands and floodplains.

A compositional multiphase model for groundwater contamination by petroleum products: 1. Theoretical considerations

Science.gov (United States)

Corapcioglu, M. Yavuz; Baehr, Arthur L.

1987-01-01

A mathematical model is developed to describe the fate of hydrocarbon constituents of petroleum products introduced to soils as an immiscible liquid from sources such as leaking underground storage tanks and ruptured pipelines. The problem is one of multiphase transport (oil (immiscible), air, and water phases) of a reactive contaminant with constituents such as benzene, toluene, and xylene found in refined petroleum products like gasoline. In the unsaturated zone, transport of each constituent can occur as a solute in the water phase, vapor in the air phase, and as an unaltered constituent in the oil phase. Additionally, the model allows for adsorption. Molecular transformations, microbially mediated or abiotic, are incorporated as sink terms in the conservation of mass equations. An equilibrium approximation, applicable to any immiscible organic contaminant is applied to partition constituent mass between the air, oil, water, and adsorbed phases for points in the region where the oil phase exists. Outside the oil plume the equilibrium approximation takes on a simpler form to partition constituent mass between the air, water, and adsorbed phases only. Microbial degradation of petroleum products is first discussed in a general model, then the conservation of mass equation for oxygen is incorporated into the analysis which takes advantage of the key role played by oxygen in the metabolism of hydrocarbon utilizing microbes in soil environments. Approximations to two subproblems, oil plume establishment in the unsaturated zone, and solute and vapor transport subsequent to immiscible plume establishment are then developed from the general model.

Pipeline monitoring using acoustic principal component analysis recognition with the Mel scale

In modern cities, many important pipelines are laid underground. In order to prevent these lifeline infrastructures from accidental damage, monitoring systems are becoming indispensable. Third party activities were shown by recent reports to be a major cause of pipeline damage. Potential damage threat to the pipeline can be identified by detecting dangerous construction equipment nearby by studying the surrounding noise. Sound recognition technologies are used to identify them by their sounds, which can easily be captured by small sensors deployed along the pipelines. Pattern classification methods based on principal component analysis (PCA) were used to recognize the sounds from road cutters. In this paper, a Mel residual, i.e. the PCA residual in the Mel scale, is proposed to be the recognition feature. Determining if a captured sound belongs to a road cutter only requires checking how large its Mel residual is. Experiments were conducted and results showed that the proposed Mel-residual-based PCA recognition worked very well. The proposed Mel PCA residual recognition method will be very useful for pipeline monitoring systems to prevent accidental breakage and to ensure the safety of underground lifeline infrastructures

Defects positioning of underground gas pipelines using MFL(magnetic flux leakage) inspection which is one of non-destructive evaluation techniques is proposed in this paper. MFL signals acquired from MFL PIG(pipeline inspection gauge) have nonlinearity and distortion caused by various extemal disturbances. SQI(self quotient image), a compensation technique for nonlinearity and distortion of MFL signal, is used to correct positioning of pipeline defects. Through the experiments using artificial defects carved in the KOGAS pipeline simulation facility, it is found that the performance of proposed defect detection is greatly improved compared to that of the conventional DCT(discrete cosine transform) coefficients based detection

Does petroleum development affect burrowing owl nocturnal space-use?

Decline all over Canada in the population of burrowing owls, a federally listed endangered species, has raised concerns about the possible influence of petroleum infrastructure development on owl nocturnal space-use while foraging. Roads, wells, pipelines and sound-producing facilities related to petroleum development change the landscape and can influence the owls' mortality risk. For 3 years, 27 breeding adult male burrowing owls with nests close to different petroleum infrastructures were captured and fitted with a miniature GPS datalogger in order to track their nocturnal foraging. Data from these GPS devices were fed into a geographical information system and showed that pipelines and wells did not alter the foraging habits of the owls. Dirt and gravel roads, with little traffic, were preferentially selected by the owls, conceivably because of higher owl mortality risk along paved roads. Sound-producing facilities did not change owls' foraging behaviour, implying that sound may not affect their nocturnal space-use. Traffic data and sound power measurements will be used in further studies in an effort to better understand burrowing owls' nocturnal foraging habits.

The deposition of paraffins in submarine pipelines poses a serious problem for the offshore petroleum production. Paraffins precipitate off oily solutions due to a temperature decrease according to the phase equilibrium conditions of the liquid-solid system. After some time, the continuous precipitation leads to deposits in the internal walls of the pipe, clogging the lines and promoting an increase in the head loss of the flow. Consequently, there is an increase in the pressure gradient required to maintain the flow, and the flow rate is reduced. A complete obstruction of the pipeline may occur. In the present work, this phenomenon was studied in a simulation of the subsea operational conditions, where the oil pipelines laying on the seabed are subjected to low temperatures, just a little above the freezing point of water. The pipeline behaves as a heat exchanger and the hot oil from the underground reservoir emerging from the wellhead is effectively cooled down to the point where paraffin precipitation occurs somewhere along the line. An experimental apparatus was built for a 25.4 mm (1 in) diameter pipe-flow model with 13 m of length, submerged in a chilling bath of near frozen water. Stream wise pressure and temperature gradients were measured, in order to evaluate the differences in the behavior of paraffin deposition between one-phase oil flow and two-phase oil-water flow.

Making petroleum equipment safe, a priority

International Nuclear Information System (INIS)

1999-01-01

Changes to the 'Act respecting the use of petroleum products' have been announced effective May 1, 1999. The changes have been made to reduce problems which can be attributed to petroleum product leaks. The new regulations will make owners and users of petroleum equipment, including underground and above-ground storage equipment and commercial storage tanks, more accountable for the use of their own equipment. The emphasis in the new regulations is based upon the storage capacity of petroleum equipment and the risks associated with this equipment, rather than the on the activities of the owners concerned. Accordingly, the new regulations call for stricter requirements for high-risk equipment, a private equipment inspection plan, a two-year operating permit, replacing the current permits and certificates, a tariff structure based on the risks associated with the equipment, and deregulation of commercial activities involving petroleum products that require no equipment. Additionally, the amendments to the Act transfer responsibility for administration to the Regie du batiment and to the Ministere des Transports. Details of each of these changes are explained

This paper reports on international pipeline construction which has entered a fast-growth period, accelerated by the new political and economic realities around the world and increasing demand for natural gas, crude oil and refined petroleum products. Many projects are under way or in planning for completion in the mid- to late 1990s in Europe, South America, Asia and the Middle East. Pipeline And Gas Journal's projection calls for construction or other work on 30,700 miles of new natural gas, crude oil and refined products pipelines in the 1992-93 period outside Canada and the U.S. These projects will cost an estimated $30 billion-plus. Natural gas pipelines will comprise most of the mileage, accounting for almost 23,000 miles at an estimated cost of $26.3 billion. Products pipelines, planned or under construction, will add another 5,800 miles at a cost of $2.8 billion. Crude oil pipelines, at a minimum, will total 1,900 new miles at a cost of slightly under $1 billion

Water Pipeline Monitoring and Leak Detection using Flow Liquid Meter Sensor

Rahmat, R. F.; Satria, I. S.; Siregar, B.; Budiarto, R.

2017-04-01

Water distribution is generally installed through underground pipes. Monitoring the underground water pipelines is more difficult than monitoring the water pipelines located on the ground in open space. This situation will cause a permanent loss if there is a disturbance in the pipeline such as leakage. Leaks in pipes can be caused by several factors, such as the pipe’s age, improper installation, and natural disasters. Therefore, a solution is required to detect and to determine the location of the damage when there is a leak. The detection of the leak location will use fluid mechanics and kinematics physics based on harness water flow rate data obtained using flow liquid meter sensor and Arduino UNO as a microcontroller. The results show that the proposed method is able to work stably to determine the location of the leak which has a maximum distance of 2 metres, and it’s able to determine the leak location as close as possible with flow rate about 10 litters per minute.

Leaks in underground pipelines can cause social, environmental and economical problems. One of a good countermeasures of leaks is to find and repair of leak points of pipes. Leak noise is a good source to identify the location of leak points of pipelines. Although there have been several methods to detect the leak location with leak noise, such as listening rods, hydrophones or ground microphones, they were not so efficient tools. In this paper, two accelerometers are used to detect leak locations which could provide an easier and efficient method. The filtering, signal processing and algorithm is described for the detection of leak location. A 120 m-long pipeline system for experiment is installed and the results with the system show that the algorithm with the two accelerometers gives very accurate pinpointing of leaks. Theoretical analysis of sound wave propagation speed in underground pipes is also described.

Detailed Leak Detection Test Plan and schedule for the Oak Ridge National Laboratory liquid low-level waste active pipelines

International Nuclear Information System (INIS)

1994-08-01

This document provides a detailed leak detection test plan and schedule for the pipelines that comprise the active, singly contained, portion of the liquid low-level waste (LLLW) system at the Oak Ridge National Laboratory (ORNL). This plan was prepared in response to the requirements of the Federal Facility Agreement for the Oak Ridge Reservation (FFA) between the U.S. Department of Energy (DOE), the U.S. Environmental Protection Agency (EPA) and the Tennessee Department of Environment and Conservation (TDEC). The LLLW system is an interconnected complex of tanks and pipelines. The FFA distinguishes four categories of tank and pipeline systems within this complex: new or replacement tank systems with secondary containment (Category A), existing tank systems with secondary containment (Category B), existing tank systems without secondary containment (Category C), and tank systems that have been removed from service (Category D). The FFA specifically requires that DOE demonstrate that the Category C systems are not leaking. This plan and schedule addresses testing of the Category C pipelines and the pipelines which are part of Category B tank systems that do not fully meet the requirements for secondary containment as listed in the FFA. A key feature of the plan is that it is based on the use of performance standards for the conduct of release detection testing, and on the use of methods whose performance has been evaluated and shown to meet those standards. Another feature of the plan is that it is based in part on relevant portions of current federal EPA regulations applicable to underground storage tanks and pipelines (UST systems) that store and transfer petroleum products and other hazardous substances. While the FFA does not require that the testing at ORNL follow these regulations, the regulations do provide industry- and regulator-accepted performance standards, as well as a schedule for repeated testing of UST components

Virtual Instrumentation Corrosion Controller for Natural Gas Pipelines

Gopalakrishnan, J.; Agnihotri, G.; Deshpande, D. M.

2012-12-01

Corrosion is an electrochemical process. Corrosion in natural gas (methane) pipelines leads to leakages. Corrosion occurs when anode and cathode are connected through electrolyte. Rate of corrosion in metallic pipeline can be controlled by impressing current to it and thereby making it to act as cathode of corrosion cell. Technologically advanced and energy efficient corrosion controller is required to protect natural gas pipelines. Proposed virtual instrumentation (VI) based corrosion controller precisely controls the external corrosion in underground metallic pipelines, enhances its life and ensures safety. Designing and development of proportional-integral-differential (PID) corrosion controller using VI (LabVIEW) is carried out. When the designed controller is deployed at field, it maintains the pipe to soil potential (PSP) within safe operating limit and not entering into over/under protection zone. Horizontal deployment of this technique can be done to protect all metallic structure, oil pipelines, which need corrosion protection.

Amendments proposed by the Government of Quebec with respect to petroleum products regulations were described. The amending regulation provides a list of works which will no longer require ministerial authorization such as the removal of petroleum equipment, the installation of spill prevention systems, electrical works and repair of fueling areas, loading and unloading zones. An owner will not be required to remove an unused underground petroleum storage tank if it can be shown that it is impervious according to prescribed pressure tests, and that the period during which the equipment has been unused does not exceed five years. The draft regulations also provide precautionary measures that have to be taken prior to abandoning a tank

European pipelines in 1993 spilled as much crude oil and petroleum products as in any year since 1971, when statistics first began to be reported. Final cost of cleanup will exceed $10 million, by far the most ever spent by western European oil pipelines operating on land. This cost figure is only preliminary: costs for three spills totaling nearly 2,600 cu m (approximately 16,380 bbl; 43.6% of total spilled) had not been reported through November 1994. Ten incidents of oil spills from pipelines occurred in 1993, compared with seven for 1992 and an average of 12.7/year since 1971. Total length of oil industry cross-country pipelines operating in Western Europe at the end of 1993 was 21,600 km, up from nearly 19,000 km in 1989. In all, 601 million cu m (3.8 billion bbl) of crude oil and refined products moved through the pipeline system. The paper briefly describes several of the accidents

It is impossible to keep petroleum and natural gas transmission pipelines free from defects in the manufacturing, installation and servicing processes. The damage might endanger the safety of pipelines and even shorten their service life; gas or petroleum release due to defects may jeopardise the surrounding ecological environments with associated economic and life costs. Pre-tensile deformation of X60 steel is employed to experimentally simulate the influence of dents on the fatigue crack initiation life. The investigation indicates that the fatigue crack initiation life of pre-deformed X60 pipeline steel can be assessed by a previously proposed energetic approach. The threshold for crack initiation increases with the pre-deformation due to a strain hardening effect, while the fatigue resistant factor exhibits a maximum with pre-deformation owing to its special dependence on fracture strain and fracture strength. The result is expected to be beneficial to the understanding of the effect of damage on the safety of pipelines and fatigue life prediction

Oil spills due to oil pipelines is a very frequent problem in Mexico. Petroleos Mexicanos (PEMEX), very concerned with the environmental agenda, has been developing inspection and correction plans for zones around oil pipelines pumping stations and pipeline right-of-way. These stations are located at regular intervals of kilometres along the pipelines. In this study, two sections of an oil pipeline and two pipeline pumping stations zones are characterized in terms of the presence of Total Petroleum Hydrocarbons (TPHs) and Polycyclic Aromatic Hydrocarbons (PAHs). The study comprehends sampling of the areas, delimitation of contamination in the vertical and horizontal extension, analysis of the sampled soils regarding TPHs content and, in some cases, the 16 PAHs considered as priority by USEPA, calculation of areas and volumes contaminated (according to Mexican legislation, specifically NOM-EM-138-ECOL-2002) and, finally, a proposal for the best remediation techniques suitable for the contamination levels and the localization of contaminants.

Natural energy problem, including the environmental aspects had changes into certain circumstances in recent years and natural gas has been a focus of constant attention from the viewpoint of energy efficiency and pollution free. From that kind of background, pipeline construction for petroleum and natural gas were considerate as energy infrastructure maintenance plan. Based on the clarification of Asian Pipeline Project (1997-2007) centered in Japan, international pipeline is needed as the natural gas is mainly transported from gas field in Russia and Middle East to consumer country such as Japan etc. It used in severe condition such as cold district and sea. In the meantime, pipeline steel is not just received damages by earth crust fluctuation and corrosion, but also suffered from the corrosion caused by anions that were dissolved in sea and groundwater. The diversification of dispersion and consumption structure of natural gas supply acceptance base are seen regarding, that made the needs of the storing are rising and dealt with the quantitative spatial expansion of the demand. By that, corrosion resistance, not only the hardness, tough, weldability, corrosiveness gas environment is extremely required. (author)

The inspection of a radiologically contaminated pipeline using a teleoperated pipe crawler

In the 1950s, the Savannah River Site built an open, unlined retention basin to temporarily store potentially radionuclide contaminated cooling water from a chemical separations process and storm water drainage from a nearby waste management facility that stored large quantities of nuclear fission byproducts in carbon steel tanks. The retention basin was retired from service in 1972 when a new, lined basin was completed. In 1978, the old retention basin was excavated, backfilled with uncontaminated dirt, and covered with grass. At the same time, much of the underground process pipeline leading to the basin was abandoned. Since the closure of the retention basin, new environmental regulations require that the basin undergo further assessment to determine whether additional remediation is required. A visual and radiological inspection of the pipeline was necessary to aid in the remediation decision making process for the retention basin system. A teleoperated pipe crawler inspection system was developed to survey the abandoned sections of underground pipelines leading to the retired retention basin. This paper will describe the background to this project, the scope of the investigation, the equipment requirements, and the results of the pipeline inspection

Norway: the traps of the petroleum wealth

Thanks to petroleum, the Norwegian population is the richness in the world. The petroleum profits have been always carefully managed and stored in a special fund. However, this richness has now a disastrous impact on the Norwegian society which is progressively falling asleep in its comfort while the economy shows signs of overheating. Oil production has started its decline and will accelerate by 2010. The strategy of Norway is now to massively invest in gas exportation and to saturate the gas pipelines towards Europe. In the future Norway has planned to export LNG to the US and Spain. (J.S.)

Water is the most treasure natural resources, however, a huge amount of water are lost during its distribution that leads to water leakage problem. The leaks meant the waste of money and created more economic loss to treat and fix the damaged pipe. Researchers and engineers have put tremendous attempts and effort, to solve the water leakage problem especially in water leakage of buried pipeline. An advanced technology of ground penetrating radar (GPR) has been established as one of the non-destructive testing (NDT) method to detect the underground water pipe leaking. This paper focuses on the ability of GPR in water utility field especially on detection of water leaks in the underground pipeline distribution. A series of laboratory experiments were carried out using 800-MHz antenna, where the performance of GPR on detecting underground pipeline and locating water leakage was investigated and validated. A prototype to recreate water-leaking system was constructed using a 4-inch PVC pipe. Different diameter of holes, i.e. ¼ inch, ½ inch, and ¾ inch, were drilled into the pipe to simulate the water leaking. The PVC pipe was buried at the depth of 60 cm into the test bed that was filled with dry sand. 15 litres of water was injected into the PVC pipe. The water leakage patterns in term of radargram data were gathered. The effectiveness of the GPR in locating the underground water leakage was ascertained, after the results were collected and verified.

The article describes the experience of the area of Social Responsibility in TRANSPETRO, a wholly Brazilian Subsidiary of PETROBRAS, which operates in the field of transport of petroleum, its by-products and gas, by way of oil and gas pipeline networks. Pipeline is the safety option for the transport of these products, but requires monitoring and the permanent management of the use and occupation of the soil and surrounding area. This care does not only depend on the Company as responsibility is much wider. Active participation by the communities affected by the operations is essential, principally in incorporating the rules of occupation and the use of the soil in the land surrounding the strips and the terminals. This participation is justified given that the action of third parties represents a significant proportion (70%) of the irregular situations registered by the Company. Community Relationship Management is one of the principal strategies to increase the safety of the pipelines integrated into the Company's programs of maintenance and operational control. Therefore, a plan of Community Relations has been implanted, focusing on the transformation of values to construct a community culture of co-habitation and co-responsibility for the pipeline land.

Safety installation for preventing pollution by pipelines

Energy Technology Data Exchange (ETDEWEB)

Wittgenstein, G F

1972-10-25

A safety installation for preventing pollution by pipelines, particularly those used for transporting liquid hydrocarbons, is described. It is applicable to any pipeline, but particularly to underground or submarine pipelines, whether made of steel, plastics, or any other material. The 4 essential objects of the invention are to insure reliable prevention of pollution of the environment due to leakage of a hydrocarbon through cracks in the pipe; to evacuate the leakage flow without delay to a vessel; to signal almost instantaneously the existence of a leak; and to effect remote control of operations by which the dynamic pressure in the pipe is cancelled. Each equipped section consists of a fluid-type jacket of plastic material which surrounds the pipe, which at its ends is sealed off. It is these seals which delimit the sections. (7 claims)

In traditional methods of pipeline leak location, geophones must be located on the pipe wall. If the exact location of the pipeline is unknown, the leaks cannot be identified accurately. To solve this problem, taking into account the characteristics of the pipeline leak, we propose a continuous random seismic source model and construct geological models to investigate the proposed method for locating underground pipeline leaks. Based on two dimensional (2D) viscoacoustic equations and the staggered grid finite-difference (FD) algorithm, the microseismic wave field generated by a leaking pipe is modeled. Cross-correlation analysis and the simulated annealing (SA) algorithm were utilized to obtain the time difference and the leak location. We also analyze and discuss the effect of the number of recorded traces, the survey layout, and the offset and interval of the traces on the accuracy of the estimated location. The preliminary results of the simulation and data field experiment indicate that (1) a continuous random source can realistically represent the leak microseismic wave field in a simulation using 2D visco-acoustic equations and a staggered grid FD algorithm. (2) The cross-correlation method is effective for calculating the time difference of the direct wave relative to the reference trace. However, outside the refraction blind zone, the accuracy of the time difference is reduced by the effects of the refracted wave. (3) The acquisition method of time difference based on the microseismic theory and SA algorithm has a great potential for locating leaks from underground pipelines from an array located on the ground surface. Keywords: Viscoacoustic finite-difference simulation; continuous random source; simulated annealing algorithm; pipeline leak location

This discussion of the Canadian petroleum industry for the year 1966 includes production statistics and operating procedures, reserve estimates, exploration and development, transportation, refining, and marketing. Most sectors of the Canadian industry had an excellent year in 1966, featured by continued exploration and development successes in the Rainbow Lake-Zama Lake region of northwestern Alberta and a record value of production that exceeded $900 million for all liquid hydrocarbons. Production of crude oil and natural gas liquids exceeded one million bopd. Crude oil producers supplied 58% of the total crude oil requirements for Canadian refineries. Oil reserves increased due primarily to the application of secondary recovery and the discovery of new reserves. Total pipeline construction decreased, and there was a small increase in refinery capacity.

The presence of humidity may be detrimental to the operation of pipelines transporting natural gas or other petroleum products. In particular conditions water solidifies or reacts chemically with hydrocarbons, forming hydrates. Such crystalline substances may cause obstruction of the lines and damage the equipment of the relevant facilities. A procedure for predicting the performance of drying a pipeline using dehumidified air with a low dew point is described in this paper. The mathematical model estimates the time required for the complete removal of moisture in the pipeline for the given operating conditions with simplified assumptions. The governing equations are solved analytically as well as numerically and the results are briefly discussed in the paper. (Author)

Expansion of the Strategic Petroleum Reserve, Alabama, Louisiana, Mississippi, and Texas: Draft environmental impact statement

International Nuclear Information System (INIS)

1992-10-01

The proposed action entails the development of a plan for 250 million barrels of new crude oil storage capacity in two Gulf Coast salt domes to expand the Strategic Petroleum Reserve pursuant to Congressional directive (PL 101--383 and PL 101--512). Storage capacity would be developed by solution-mining the salt which would require about two billion barrels of surface water and would generate about two billion barrels of salt brine. The brine would be disposed of primarily by ocean discharge and alternatively by deep underground injection. Crude oil fill and distribution systems would require new pipelines and terminal facilities. This EIS assesses the impacts of construction and operation for the range of alternatives being considered and focuses on oil and brine spill risk and impacts of brine disposal, water and land use, groundwater contamination, hydrocarbon emissions, and involvement with wetlands and floodplains. This volume focuses on the environmental risks and public occupational health and safety, environmental impacts, regulatory requirements and mitigation methods, the relationship between local short-term use and long-term productivity, and the commitment of resources

Investigating an effective supply chain for a refinery in a regulated petroleum sector

Directory of Open Access Journals (Sweden)

Chris Adendorf

2012-12-01

Full Text Available Currently, refined petroleum products are manufactured by six refineries in South Africa. The supply of refined petroleum products is supplemented by imports of refined petroleum products. These refined petroleum products are transported by pipeline, rail, road, sea and a combination thereof to depots across the country. These products are then distributed directly to commercial customers through points of resale in the form of retail service stations. The challenge is that the storage facilities and distribution networks in South Africa are currently utilised to its full capacity. There is a need to expand current storage infrastructure or to erect new storage facilities to facilitate imports. Durban Port that currently handles 70% of the country’s crude oil and 40% of refined products is also utilised to its full capacity. The investigated problem pertains to the limited storage and transport capacity available for the distribution of petroleum products in the country. The interview protocol, which was based on the literature reviewed, was used for compiling the primary data for the case study. Selected findings revealed that the respondents perceived that storage capacity is the most significant constraint militating against adequate supply by the supply chain. The findings also indicated that the respondents were of the opinion that transport rates and routes (cost of logistics are the greatest contributor to the prices of products. As a result, there appears to be a major scope for improvement in terms of the usage of pipelines and rails for the movement of petroleum products.

In this paper, the dependences of the stress-strain state and subsidence of pipelines on the dimensions of the subsidence zone are obtained for the sizes of pipes that have become most widespread during the construction of main oil pipelines (530x10, 820x12, 1020x12, 1020x14, 1020x16, 1220x14, 1220x16, 1220x18 mm). True values of stresses in the pipeline wall, as well as the exact location of maximum stresses for the interval of subsidence zones from 5 to 60 meters, are determined. For this purpose, the authors developed a finite element model of the pipeline that takes into account the actual interaction of the pipeline with the subgrade and allows calculating the SSS of the structure for a variable subsidence zone. Based on the obtained dependences for the underground laying of oil pipelines in permafrost areas, it is proposed to artificially limit the zone of possible subsidence by separation supports from the soil with higher building properties and physical-mechanical parameters. This technical solution would significantly reduce costs when constructing new oil pipelines in permafrost areas.

Crossing Active Faults on the Sakhalin II Onshore Pipeline Route: Pipeline Design and Risk Analysis

International Nuclear Information System (INIS)

Mattiozzi, Pierpaolo; Strom, Alexander

2008-01-01

Twin oil (20 and 24 inch) and gas (20 and 48 inch) pipeline systems stretching 800 km are being constructed to connect offshore hydrocarbon deposits from the Sakhalin II concession in the North to an LNG plant and oil export terminal in the South of Sakhalin island. The onshore pipeline route follows a regional fault zone and crosses individual active faults at 19 locations. Sakhalin Energy, Design and Construction companies took significant care to ensure the integrity of the pipelines, should large seismic induced ground movements occur during the Operational life of the facilities. Complex investigations including the identification of the active faults, their precise location, their particular displacement values and assessment of the fault kinematics were carried out to provide input data for unique design solutions. Lateral and reverse offset displacements of 5.5 and 4.5 m respectively were determined as the single-event values for the design level earthquake (DLE) - the 1000-year return period event. Within the constraints of a pipeline route largely fixed, the underground pipeline fault crossing design was developed to define the optimum routing which would minimize stresses and strain using linepipe materials which had been ordered prior to the completion of detailed design, and to specify requirements for pipe trenching shape, materials, drainage system, etc. Detailed Design was performed with due regard to actual topography and to avoid the possibility of the trenches freezing in winter, the implementation of specific drainage solutions and thermal protection measures

Smolij, N.I.; Nikitin, A.S.

1980-01-01

Seismic-safe conditions for performing drill-blasting operations in the vicinity of underground gas pipelines when constructing thermal- or nuclear power plants are discussed. It is shown that, for the determination of seismic-safe parameters, of drill-blasting operations, the maximum permissible level of seismic loads should be specified taking into account the mechanical properties of the pipeline.metal, structural parameters of the gas pipeline and the pressure of the medium transported. Besides, the seismic effect of the blast should be considered with regard to particular conditions of blasting and rock properties. The equations and diagrams used in the calculation are given

CO2 slurry pipeline to transport solid marketable products to improve CCS economics

Energy Technology Data Exchange (ETDEWEB)

Luhning, Richard

2010-09-15

Carbon dioxide pipelines are anticipated to be a key element in CCS (Carbon Capture and Sequestration) to transport the carbon dioxide to sequestration sites or to oil fields for use in enhanced oil recovery applications. However the economics of CCS are such that the operations are economically challenged. The concept of using super critical (liquid) carbon dioxide in a slurry pipeline is to use the pipeline constructed for environmental purposes to transport marketable products such as sulphur, petroleum coke, limestone and others to market thereby generating additional income to make CCS carbon dioxide transportation economically attractive.

Induced AC voltages on pipelines may present a serious hazard

International Nuclear Information System (INIS)

Kirkpatrick, E.L.

1997-01-01

The problem of induced AC voltages on pipelines has always been with us. Early pipeline construction consisted of bare steel or cast iron pipe, which was very well grounded. Bell and spigot, mechanical, or dresser-style joint couplings often were used, creating electrically discontinuous pipelines which are less susceptible to AC induction. Although induced AC affects any pipeline parallel to a high-voltage alternating current (HVAC) power line, the effects were not noticeable on bare pipelines. With the advent of welded steel pipelines, modern cathodic protection (CP) methods and materials, and the vastly improved quality of protective coatings, induced AC effects on pipelines have become a significant consideration on many pipeline rights-of-way. In the last two to three decades, one has been seeing much more joint occupancy of the same right-of-way by one or more pipelines and power lines. As the cost of right-of-way and the difficulty in acquisition, particularly in urban areas, have risen, the concept of joint occupancy rights-of-way has become more attractive to many utility companies. Federal and state regulations usually insist on joint-use right-of-way when a utility proposes crossing regulated or publicly owned lands, wherever there is an existing easement. Such joint use allows the induced AC phenomena to occur and may create electrical hazards and interference to pipeline facilities. Underground pipelines are especially susceptible if they are well-coated and electrically isolated for CP

Pipeline capacity and heavy oil markets

International Nuclear Information System (INIS)

Scott, G.R.

1993-01-01

Aspects of transporting heavy crude to markets from Canadian sources are discussed, with reference to pipeline expansion, western Canadian crude supply, and exports to various Petroleum Administration for Defense Districts (PADDs) in the USA. Pipeline expansions have been proposed by Interprovincial Pipeline, Trans Mountain Pipeline, Rangeland, and Wascana, and some of these proposals are in the review stage. Western Canadian crude supply is expected to peak at 1.9 million bbl/d in 1996. An increase in heavy crude supply is expected but this increase will not be sufficient to offset a decline in light crude supply. Adequate pipeline capacity should exist with the Interprovincial expansion volume of 170,000 bbl/d and the Trans Mountain expansion of 38,000 bbl/d forecast to be in place by 1995. Canadian crude exports to the USA have steadily increased since 1989, and heavy crude exports have grown an average of 20,000 bbl/d each year. In PADD Region IV, oil production is declining and ca 20,000 bbl/d of heavy crude will be needed by the year 2000; additional pipeline capacity will be required. In PADD Region II, Canadian heavy crude imports are ca 390,000 bbl/d and further market opportunities exist, after the Interprovincial expansion is complete. When the various combinations of possible pipeline expansions or reversals are considered, a range of heavy crude near-term growth potentials is obtained in which Canadian heavy oil would displace offshore heavy oil supplied to USA refineries. This potential is seen to range from 35,000 bbl/d to 200,000 bbl/d. 7 refs., 20 figs., 3 tabs

Pipelines and salmon in northern British Columbia : potential impacts

International Nuclear Information System (INIS)

Levy, D.A.

2009-10-01

Four pipeline projects have been proposed for northern British Columbia that could threaten the health of the Fraser, Skeena, and Kitimat watersheds. The pipelines will expose salmon to risks on several fronts. Enbridge's Northern Gateway pipeline project has generated the most concern for a several reasons, including the risks to salmon and freshwater habitat from pipeline failures, notably leaks or ruptures. This paper reviewed the salmon resources in affected watersheds; salmon and BC's economy; salmon diversity and abundance; impacts on fish from pipeline construction, operations and failures; behaviours of different petroleum products in fresh water; hydrocarbon toxicity; history of pipeline failures; sabotage and natural disasters; and Canadian case studies. Salmon are already experiencing stresses from forestry, hydro-electricity, transportation, agriculture, mining, mountain pine beetle, climate change and coalbed methane development. Their cumulative impact will dictate the long-term health and viability of salmon. It was concluded that if all of the proposed pipelines were built, they would extend over 4,000 km, crossing more than 1,000 rivers and streams in some of Canada's most productive salmon habitat. During construction, pipeline stream crossings are vulnerable to increased sedimentation, which can degrade salmon habitat. In the event of a spill, the condensate and oil sands products carried in the pipelines are highly toxic to salmon, with serious and lasting adverse impacts on salmon and their habitat. Any decision to approve such a pipeline should be made in recognition of these risks. 73 refs., 5 tabs., 15 figs., 2 appendices.

Bruce, W.A. [Edison Welding Inst., Columbus, OH (United States)

2000-07-01

Corrosion damage on pipelines represents the second most important cause of damage to natural gas pipelines in the United States. The area containing the corrosion damage must be reinforced to prevent the pipeline to rupture and from bulging. The predominant method of reinforcing corrosion damage in cross-country pipelines is to install a full-encirclement repair sleeve. The recent up-date of American Petroleum Institute (API) code requirement for repair of in-service pipelines by welding was published to provide a recommended practice for pipeline maintenance welding. The recent changes to the code are explained. The appendix B to the up-date is intended to alleviate redundancy between API 1104 and API 1107 and the time lag between up-dates, and to address technological advances made in the area of in-service welding. An alternative repair method of deposited weld metal, or weld deposition repair is briefly explained. 9 refs., 5 figs.

Milidiu, R.L.; Santos Liporace, F. [Pontificia Univ. Catolica, Rio de Janeiro (Brazil). Dept. de Informatica

2004-07-01

This paper explored issues facing the complex task of managing pipelines that transport large volumes of petroleum products over long distances. Since oil pipelines are generally a few inches wide and several miles long, reasonable amounts of distinct products can be transported with very small loss due to the mixing at liquid boundaries. Optimizing the transportation through oil pipelines in terms of maintenance and environmental safety is a high priority for pipeline operators. This paper presented the Pipesworld model which takes into account features such as product interface constraints, limited product storage capacities and due dates for product delivery. It has been benchmarked as a start-of-art general purpose artificial planning system. This paper also reported the results derived by general purpose artificial intelligence planning systems when applied to the Pipesworld model. It demonstrated how various modelling techniques can be used to enhance the planners performance. Current work in developing Plumber was also presented. This dedicated solver that addresses operational situations uses both general purpose planning techniques as well as domain specific knowledge. When Plumber was incorporated into Pipesworld, its outperformed Fast-Forward, one of the best available general purpose planning systems, suggesting that improved versions of Plumber have the potential to deal with various problem scenarios in pipeline operations. 11 refs., 2 tabs., 3 figs.

Field investigation and analysis of buried pipelines under various seismic environments. Technical report

Energy Technology Data Exchange (ETDEWEB)

Wang, L.R.L.

1982-08-01

A research project is proposed in which the behavior of oil, water, sewer, and gas pipelines under various seismic environments, including seismic shaking and large ground deformation would be investigated. It is suggested that the investigation be conducted in the Beijing and Tangshan areas. Three major hazards to underground pipelines are identified: the effect of wave propagation; ground rupture and differential movement along fault lines; and soil liquefaction induced by ground shaking. Ruptures or severe distortions of the pipe are most often associated with fault movements, landslides, or ground squeeze associated with fault zones. A model is presented to evaluate the general longitudinal responses of buried pipelines, both segmented and continuous, subjected to ground shakings and vibrations. The results of these tests will be used to develop aseismic codes for buried pipelines.

Oil pipeline performance review 1995, 1996, 1997, 1998 : Technical/statistical report

International Nuclear Information System (INIS)

2000-12-01

This document provides a summary of the pipeline performance and reportable pipeline failures of liquid hydrocarbon pipelines in Canada, for the years 1995 through 1998. The year 1994 was the last one for which the Oil Pipeline Performance Review (OPPR) was published on an annual basis. The OPPR will continue to be published until such time as the Pipeline Risk Assesment Sub-Committee (PRASC) has obtained enough pipeline failure data to be aggregated into a meaningful report. The shifts in the mix of reporting pipeline companies is apparent in the data presented, comparing the volumes transported and the traffic volume during the previous ten-year period. Another table presents a summary of the failures which occurred during the period under consideration, 1995-1998, allowing for a comparison with the data for the previous ten-year period. From the current perspective and from an historical context, this document provides a statistical review of the performance of the pipelines, covering refined petroleum product pipelines, clean oil pipelines and High Vapour Pressure (HVP) pipelines downstream of battery limits. Classified as reportable are spills of 1.5 cubic metre or more of liquid hydrocarbons, any amount of HVP material, any incident involving an injury, a death, a fire, or an explosion. For those companies that responded to the survey, the major items, including number of failures and volumes released are accurate. Samples of the forms used for collecting the information are provided within the document. 6 tabs., 1 fig

Energy intensity, life-cycle greenhouse gas emissions, and economic assessment of liquid biofuel pipelines.

Science.gov (United States)

Strogen, Bret; Horvath, Arpad; Zilberman, David

2013-12-01

Petroleum fuels are predominantly transported domestically by pipelines, whereas biofuels are almost exclusively transported by rail, barge, and truck. As biofuel production increases, new pipelines may become economically attractive. Location-specific variables impacting pipeline viability include construction costs, availability and costs of alternative transportation modes, electricity prices and emissions (if priced), throughput, and subsurface temperature. When transporting alcohol or diesel-like fuels, pipelines have a lower direct energy intensity than rail, barge, and trucks if fluid velocity is under 1 m/s for 4-inch diameter pipelines and 2 m/s for 8-inch or larger pipelines. Across multiple hypothetical state-specific scenarios, profit-maximizing design velocities range from 1.2 to 1.9 m/s. In costs and GHG emissions, optimized pipelines outperform trucks in each state and rail and barge in most states, if projected throughput exceeds four billion liters/year. If emissions are priced, optimum design diameters typically increase to reduce pumping energy demands, increasing the cost-effectiveness of pipeline projects. Copyright © 2013 Elsevier Ltd.

Pipeline Decommissioning Trial AWE Berkshire UK - 13619

Energy Technology Data Exchange (ETDEWEB)

Agnew, Kieran [AWE, Aldermaston, Reading, RG7 4PR (United Kingdom)

2013-07-01

This Paper details the implementation of a 'Decommissioning Trial' to assess the feasibility of decommissioning the redundant pipeline operated by AWE located in Berkshire UK. The paper also presents the tool box of decommissioning techniques that were developed during the decommissioning trial. Constructed in the 1950's and operated until 2005, AWE used a pipeline for the authorised discharge of treated effluent. Now redundant, the pipeline is under a care and surveillance regime awaiting decommissioning. The pipeline is some 18.5 km in length and extends from AWE site to the River Thames. Along its route the pipeline passes along and under several major roads, railway lines and rivers as well as travelling through woodland, agricultural land and residential areas. Currently under care and surveillance AWE is considering a number of options for decommissioning the pipeline. One option is to remove the pipeline. In order to assist option evaluation and assess the feasibility of removing the pipeline a decommissioning trial was undertaken and sections of the pipeline were removed within the AWE site. The objectives of the decommissioning trial were to: - Demonstrate to stakeholders that the pipeline can be removed safely, securely and cleanly - Develop a 'tool box' of methods that could be deployed to remove the pipeline - Replicate the conditions and environments encountered along the route of the pipeline The onsite trial was also designed to replicate the physical prevailing conditions and constraints encountered along the remainder of its route i.e. working along a narrow corridor, working in close proximity to roads, working in proximity to above ground and underground services (e.g. Gas, Water, Electricity). By undertaking the decommissioning trial AWE have successfully demonstrated the pipeline can be decommissioned in a safe, secure and clean manor and have developed a tool box of decommissioning techniques. The tool box of includes

Oliver, Dean S.; Reynolds, Albert C.; Liu, Ning

This book is a guide to the use of inverse theory for estimation and conditional simulation of flow and transport parameters in porous media. It describes the theory and practice of estimating properties of underground petroleum reservoirs from measurements of flow in wells, and it explains how to characterize the uncertainty in such estimates. Early chapters present the reader with the necessary background in inverse theory, probability and spatial statistics. The book demonstrates how to calculate sensitivity coefficients and the linearized relationship between models and production data. It also shows how to develop iterative methods for generating estimates and conditional realizations. The text is written for researchers and graduates in petroleum engineering and groundwater hydrology and can be used as a textbook for advanced courses on inverse theory in petroleum engineering. It includes many worked examples to demonstrate the methodologies and a selection of exercises.

1969-12-01

This study covers the following Canadian petroleum industry categories: (1) a brief history; (2) the demand for Alberta crude; (3) U.S. oil policies; (4) overseas exploration; (5) the national oil policy; (6) the Montreal pipeline and its targets; (7) a continental oil policy; and (8) the impact of Arctic reserves. It is noted that large potential benefits will improve from the Manhattan navigating the Northwest Passage. Without prejudging the analysis now applied to the information gathered on this voyage, the Manhattan has greatly contributed to the solution of the problem of access to the Arctic islands. The picture for natural gas is less fraught with uncertainties. Unlike oil, where domestic and international considerations may weigh in U.S. policy decision, Canadian natural gas is likely to be allowed to enjoy its full economic potential in bridging the foreseeable U.S. supply gap and, inasmuch as this potential is ultimately tied with that for crude oil markets, the anticipated U.S. needs for Canadian natural gas may be expected to enhance U.S. interest in the overall well-being of the Canadian petroleum industry.

Improved estimation of leak location of pipelines using frequency band variation

Leakage is an important factor to be considered for the management of underground water supply pipelines in a smart water grid system, especially if the pipelines are aged and buried under the pavement or various structures of a highly populated city. Because the exact detection of the location of such leaks in pipelines is essential for their efficient operation, a new methodology for leak location detection based on frequency band variation, windowing filters, and probability is proposed in this paper. Because the exact detection of the leak location depends on the precision of estimation of time delay between sensor signals due to leak noise, some window functions that offer weightings at significant frequencies are applied for calculating the improved cross-correlation function. Experimental results obtained by applying this methodology to an actual buried water supply pipeline, ∼ 253.9 m long and made of cast iron, revealed that the approach of frequency band variation with those windows and probability offers better performance for leak location detection.

Application of Morphological Segmentation to Leaking Defect Detection in Sewer Pipelines

Directory of Open Access Journals (Sweden)

Tung-Ching Su

2014-05-01

Full Text Available As one of major underground pipelines, sewerage is an important infrastructure in any modern city. The most common problem occurring in sewerage is leaking, whose position and failure level is typically identified through closed circuit television (CCTV inspection in order to facilitate rehabilitation process. This paper proposes a novel method of computer vision, morphological segmentation based on edge detection (MSED, to assist inspectors in detecting pipeline defects in CCTV inspection images. In addition to MSED, other mathematical morphology-based image segmentation methods, including opening top-hat operation (OTHO and closing bottom-hat operation (CBHO, were also applied to the defect detection in vitrified clay sewer pipelines. The CCTV inspection images of the sewer system in the 9th district, Taichung City, Taiwan were selected as the experimental materials. The segmentation results demonstrate that MSED and OTHO are useful for the detection of cracks and open joints, respectively, which are the typical leakage defects found in sewer pipelines.

Applicability of petroleum horizontal drilling technology to hazardous waste site characterization and remediation

International Nuclear Information System (INIS)

Goranson, C.

1992-09-01

Horizontal wells have the potential to become an important tool for use in characterization, remediation and monitoring operations at hazardous waste disposal, chemical manufacturing, refining and other sites where subsurface pollution may develop from operations or spills. Subsurface pollution of groundwater aquifers can occur at these sites by leakage of surface disposal ponds, surface storage tanks, underground storage tanks (UST), subsurface pipelines or leakage from surface operations. Characterization and remediation of aquifers at or near these sites requires drilling operations that are typically shallow, less than 500-feet in depth. Due to the shallow nature of polluted aquifers, waste site subsurface geologic formations frequently consist of unconsolidated materials. Fractured, jointed and/or layered high compressive strength formations or compacted caliche type formations can also be encountered. Some formations are unsaturated and have pore spaces that are only partially filled with water. Completely saturated underpressured aquifers may be encountered in areas where the static ground water levels are well below the ground surface. Each of these subsurface conditions can complicate the drilling and completion of wells needed for monitoring, characterization and remediation activities. This report describes some of the equipment that is available from petroleum drilling operations that has direct application to groundwater characterization and remediation activities. A brief discussion of petroleum directional and horizontal well drilling methodologies is given to allow the reader to gain an understanding of the equipment needed to drill and complete horizontal wells. Equipment used in river crossing drilling technology is also discussed. The final portion of this report is a description of the drilling equipment available and how it can be applied to groundwater characterization and remediation activities

The radioisotope method of leakproof control and leak localization has the following advantages: simplicity, short time of duration of experiment, low cost, short time need for adaptation of the object for the control, high sensitivity of measurements. Owing the application of the isotope technique is possible to carry out the expertise at low pressure, which permits to avoid strength effort of the construction materials. Through the radioisotope method is not a strength test it is complementary to pressure test (hydraulic or pneumatic). It should be noted that the hydraulic test cannot be applied to some technological objects despite the need of their leakproof control. The presentation deals with principles of application of the radioactive tracer - methyl bromide with Br-82, its preparation and ways of injecting the tracer and carrying out radiometric measurements in dependence on the kind of the object examined. The radioisotope tracer method for leakproof control of technological objects and underground pipelines as well as the apparatus used for this control have been developed in the Institute of Nuclear Chemistry and Technology and have been routinely used.

Nowadays a great effort has been spent by companies to improve their logistics in terms of programming of events that affect production and distribution of products. In this case, simulation can be a valuable tool for evaluating different behaviors. The objective of this work is to build a discrete event simulation model for scheduling of operational activities in complexes containing one harbor and two refineries interconnected by a pipeline infrastructure. The model was developed in Arena package, based on three sub-models that control pier allocation, loading of tanks, and transfers to refineries through pipelines. Preliminary results obtained for a given control policy, show that profit can be calculated by taking into account many parameters such as oil costs on ships, pier using, over-stay of ships and interface costs. Such problem has already been considered in the literature but using different strategies. All these factors should be considered in a real-world operation where decision making tools are necessary to obtain high returns. (author)

Pipelining Liquefied Petroleum Gas (LPG) is a mode of LPG transportation more environmentally-friendly than others due to the lower energy consumption and exhaust emissions. Worldwide, there are over 20000 kilometers of LPG pipelines. There are a number of codes that industry follows for the design, fabrication, construction and operation of liquid LPG pipelines. However, no standards exist to modelling particular critical phenomena which can occur on these lines due to external environmental conditions like the solar radiation pressurization. In fact, the solar radiation can expose above ground pipeline sections at pressure values above the maximum Design Pressure with resulting risks and problems. The present work presents an innovative practice suitable for the Oil & Gas industry to modelling the pressurization induced by the solar radiation on above ground LPG pipeline sections with the application to a real case.

Highlights: • Observed external-corrosion defects in underground pipelines revealed a tendency to cluster. • The Poisson distribution is unable to fit extensive count data for these type of defects. • In contrast, the negative binomial distribution provides a suitable count model for them. • Two spatial stochastic processes lead to the negative binomial distribution for defect counts. • They are the Gamma-Poisson mixed process and the compound Poisson process. • A Rogeŕs process also arises as a plausible temporal stochastic process leading to corrosion defect clustering and to negative binomially distributed defect counts. - Abstract: The spatial distribution of external corrosion defects in buried pipelines is usually described as a Poisson process, which leads to corrosion defects being randomly distributed along the pipeline. However, in real operating conditions, the spatial distribution of defects considerably departs from Poisson statistics due to the aggregation of defects in groups or clusters. In this work, the statistical analysis of real corrosion data from underground pipelines operating in southern Mexico leads to conclude that the negative binomial distribution provides a better description for defect counts. The origin of this distribution from several processes is discussed. The analysed processes are: mixed Gamma-Poisson, compound Poisson and Roger’s processes. The physical reasons behind them are discussed for the specific case of soil corrosion.

Microbial activity in petroleum reservoirs has been implicated in a suite of detrimental effects including deterioration of petroleum quality, increases in oil sulfur content, biofouling of steel pipelines and other infrastructures, and well plugging. Here, we present a biogeochemical approach, using phospholipid fatty acids (PLFAs), for detecting viable bacteria in petroleum systems. Variations within the bacterial community along water flow paths (producing well, topside facilities, and injection well) can be elucidated in the field using the same technique, as shown here within oil production plants in the Molasse Basin of Upper Austria. The abundance of PLFAs is compared to total cellular numbers, as detected by qPCR of the 16S rDNA gene, to give an overall comparison between the resolutions of both methods in a true field setting. Additionally, the influence of biocide applications on lipid- and DNA-based quantification was investigated. The first oil field, Trattnach, showed significant PLFA abundances and cell numbers within the reservoir and topside facilities. In contrast, the second field (Engenfeld) showed very low PLFA levels overall, likely due to continuous treatment of the topside facilities with a glutaraldehyde-based antimicrobial. In comparison, Trattnach is dosed once per week in a batch fashion. Changes within PLFA compositions across the flow path, throughout the petroleum production plants, point to cellular adaptation within the system and may be linked to shifts in the dominance of certain bacterial types in oil reservoirs versus topside facilities. Overall, PLFA-based monitoring provides a useful tool to assess the abundance and high-level taxonomic diversity of viable microbial populations in oil production wells, topside infrastructure, pipelines, and other related facilities.

Velazquez, J. C.; Caleyo, F.; Valorm, A.; Hallen, J. M.

2011-01-01

New deterministic and stochastic predictive models are proposed for external pitting corrosion in underground pipelines. The deterministic model takes into consideration the local chemical and physical properties of the soil as well as the pipeline coating to predict the time dependence of pitting depth and rate in a range of soils. This model, based on results from a field study, was used to conduct Monte Carlo simulations that established the probability distribution of pitting depth and growth rate in the studied soils and their evolution over the life of the pipeline. In the last stage of the study, an empirical Markov chain-based stochastic model was developed for predicting the evolution of pitting corrosion depth and rate distributions from the observed properties of the soil.

An overview of the Canadian pipeline industry's initiatives to limit greenhouse gas (GHG) emissions was presented. The commitment of the Canadian Energy Pipeline Association (CEPA) and its 11 member companies to the Voluntary Climate Change Challenge Program which aims to stabilize GHG emissions at 1990 levels by the year 2000, was reaffirmed. At the same time, questions were raised about whether the absolute reduction of greenhouse gas emissions to 1990 levels is a realistic or desirable goal for the Canadian transmission pipeline industry, given the increased demand for Canadian gas and petroleum products both domestically and internationally. it was argued that the Voluntary Climate Change Challenge Program must recognize the differing abilities of Canada's economic sectors to achieve absolute reductions in greenhouse gas emissions

An acoustic-wave sensor apparatus and method are disclosed. The apparatus for analyzing a normally liquid petroleum-based composition includes at least one acoustic-wave device in contact with the petroleum-based composition for sensing or detecting the presence of constituents (e.g. paraffins or petroleum waxes) therein which solidify upon cooling of the petroleum-based composition below a cloud-point temperature. The acoustic-wave device can be a thickness-shear-mode device (also termed a quartz crystal microbalance), a surface-acoustic-wave device, an acoustic-plate-mode device or a flexural plate-wave device. Embodiments of the present invention can be used for measuring a cloud point, a pour point and/or a freeze point of the petroleum-based composition, and for determining a temperature characteristic of each point. Furthermore, measurements with the acoustic-wave sensor apparatus can be made off-line by using a sample having a particular petroleum-based composition; or in-situ with the petroleum-based composition contained within a pipeline or storage tank. The acoustic-wave sensor apparatus has uses in many different petroleum technology areas, including the recovery, transport, storage, refining and use of petroleum and petroleum-based products. 7 figs.

This paper represents a proper technique called a pig method technique. This technique was applied for leakage detection on the 10 inch diameter and 54 km long underground pipeline carrying the crude oil derivatives from Albrega pumping station (Alzawia) to the Tareeq Almatar distribution center (Tripoli). For this technique, a suitable radioisotope ( 82 BR) was produced through irradiation of potassium bromide target under flux of 1014 n/cm 2 .sec. After 24 hours cooling of the target, 74 GBq (2 Ci) activity was achieved. The chemical reaction to get the radioactive source in a gaseous form was carried on in a special generator. A generated Methyl bromide gas was injected into the pipeline fluid stream (Light Naphtha), and then DN-1 water proof detector was lunched in the same pipeline, afterwards analysis of the obtained data from the detector passage in the pipeline indicated that no changes in the background activity a long the pipeline except the markers positions. This result proved that the pipeline was free of leaks (author)

Central Florida Pipeline Company (CFPL), a subsidiary of GATX Terminals Corp., Tampa, FL, has used directional drilling under seven water bodies in Hillsborough, Polk and Osceola Counties in constructing its new pipeline from Tampa to Orlando. Primary reason for using directional drilling is to protect the environment by minimizing water turbidity while the 16-inch diameter, 109-mile refined petroleum products pipeline is being installed. Total cost of the project is pegged at $68.5 million. Directional drilling enabled the pipe to be placed about 20 feet below the bottom of: The Alafia River in Riverview with 999 feet drilled; Port Sutton Channel near the Port of Tampa with 2,756 feet drilled; Reedy Creek Swamp at the intersection of Interstate 4 and Highway 192 which had 1,111 feet drilled; Wetland number-sign 70 southwest of Lake Wales with 1,575 feet drilled; Peace River south of Bartow had 2,470 feet drilled; Bonnet Creek west of Kissimmee had 693 feet drilled. Shingle Creek near the borders of Osceola and Orange Counties with 1,700 feet drilled.

Pipeline leak detection using volatile tracers

International Nuclear Information System (INIS)

Thompson, G.M.; Golding, R.D.

1993-01-01

A method of leak detection for underground storage tanks and pipelines adds volatile tracers to the products in the tanks and analyzes the surrounding shallow soil gases for tracer vapors. This method has several advantages: the success of the test is not limited by the size and structural design of the vessels, tanks can be tested at any fill level without taking the tank out of service, the location of a leak along a pipeline is clearly marked by the location of the tracer, and liquid leaks as small as 0.2 liters per hour (lph) can be detected. A limitation is: the backfill material must have some degree of air permeability in the zone above the water table. Several field tests document the success achieved using this method. A tracer leak detection system was installed at Homestead AFB after several other testing methods failed to locate a leak at a valve pit location along approximately 4 kilometers of fuel transfer piping. The leak was detected to the side of the valve pit at a depth of approximately 2.5 meters below the ground surface. Another installation of Edwards AFB involved the collection of 415 soil gas samples along approximately 3,050 meters of 15.25-centimeter fiberglass pipeline. Fourteen separate leaks were detected

Intelligent leak detection is an essential component of a underground water supply pipeline network such as a smart water grid system. In this network, numerous leak detection sensors are needed to cover all of the pipelines in a specific area installed at specific regular distances. It is also necessary to determine the existence of any leaks and estimate its location within a short time after it occurs. In this study, the leak signal properties and feasibility of leak location detection were investigated when concurrent leaks occurred at two points in a pipeline. The straight distance between the two leak sensors in the 100A sized cast-iron pipeline was 315.6 m, and their signals were measured with one leak and two concurrent leaks. Each leak location was described after analyzing the frequency properties and cross-correlation of the measured signals.

Foreign Experience of Applying the Principle of "Pump or Pay" in the Field of Pipeline Transportation

Directory of Open Access Journals (Sweden)

Valeriy I. Salygin

2015-01-01

Full Text Available This article reveals the practice of "ship or pay" principle in the US, Canada and Europe. The authors analyze the practice of concluding contracts for oil and petroleum products transportation, procedures, terms and conditions stipulated in the contract. The "take or pay" principle is a common practice in developed countries like the US, Canada and the UK. The specific feature of the United States is that the pipelines are not built only for one shipper, but rather for all market, which is caused the "open season" tradition. In Canada, "take or pay" principle applies to cover the capital costs of the carrier. The main reasons for usage of terms "take or pay" are to minimize risks of the carrier, building or expanding his own pipeline network, by guaranteeing shipper's financial benefits after the putting pipeline into operation. "Take or pay" contracts cover the carrier's obligation to provide agreed minimum amount of petroleum to the consignor within a certain period. In turn, the shipper is obliged to accept the minimum amount of petroleum and pay, regardless of the fact of acceptance of oil. "Take or pay" principle is a kind of risk-sharing mechanism, which allows to shift the risks of non-fulfillment of the contract to the shipper. Besides, the "take or pay" principle can be indirect guarantee in the context of project financing, and therefore, financing. The article emphasizes the main advantages of the application of this principle and opportunities for its use in Russia.

The Department of Energy's Strategic Petroleum Reserve Program began discharging brine into the Gulf of Mexico from its West Hackberry site near Cameron, Louisiana in May 1981. The brine originates from underground salt domes being leached with water from the Intracoastal Waterway, making available vast underground storage caverns for crude oil. The effects of brine discharge on aquatic organisms are presented in this volume. The topics covered are: benthos; nekton; phytoplankton; zooplankton; and data management.

Studies on the earthquake resistance design of underground site for such large important structures as nuclear power plants, high-level radioactive waste repositories, LNG tanks, petroleum tanks, big power transmission installations and compressed air energy storage installations have been examined at our research institute. The observations of earthquake have been examined at Shiroyama underground hydroelectric power station since July 1976 as one of the demonstration of the earthquake resistance, and the first report was already published. After the time accelerometers and dynamic strain meters were additionally installed. Good acceleration waves and dynamic strain waves of the Izu-Hanto-Toho-Oki Earthquake, June 29, 1980 were observed at Shiroyama site, at which the hypocentral distance is 77 km and the intensity scale is about 4. In this report, the characteristic of the oscillation wave in the neighborhood of underground cavity and the relationships among accelerations, velocities, deformations and dynamic strains are studied in detail on the above earthquake data.

These guidelines provide a site management process designed particularly for soil and groundwater pollution originating from existing or former petroleum storage tank (PST) facilities and provide uniform standards for the remediation of polluted PST sites in Alberta. The numerical criteria, risk management objectives and technical information described in this document were compiled from four documents including Remediation Guidelines for Petroleum Storage Tank Sites 1994, the Canada-Wide Standards for Petroleum Hydrocarbons in Soil, Alberta Soil and Water Quality Guidelines for Hydrocarbons at Upstream Oil and Gas Facilities, and Guidelines for Managing Risks at Contaminated Sites in Alberta. The changes in these updated guidelines reflect new remediation criteria and provide a process for determining alternate site-specific management objectives for more petroleum storage tank sites. The guidelines were developed using a risk-based approach that ensures the protection of human health, safety and the environment. The guidelines apply to aboveground and underground storage tank facilities that contain gasoline, diesel, heating oil, and aviation fuel. The guidelines specify requirements by Alberta Environment and the Alberta Fire Code. The chapter on risk management process included information on site investigation, determination of soil type, pollution source removal, land use assessment, selection of exposure pathways, depth of remediation, human inhalation and groundwater protection pathways, and verification of remediation. figs, 4 tabs., 2 appendices.

Gas elephants: Arctic projects revived by expanding markets and pipelines

International Nuclear Information System (INIS)

Jaremko, G.

2000-01-01

The revival of interest in Arctic natural gas and the developing competition to extend the pipeline grid to Alaska and the Yukon and the Northwest territories are the subject of this report. Substantial agreement between competing interest groups is reported with respect to the need for Arctic gas and the willingness of the market to pay for bringing it south to consumers. The discussion centers on the construction of the Alliance Pipeline Project that will reportedly bring two billion cubic feet per day of excess capacity to transport natural gas from northeastern British Columbia to Chicago, and the 2,400 km long Foothills Pipelines System that carries about one-third of Canadian gas exports to middle-western states and California. Plans are to extend the line to 5,240 km by laying pipe in a giant Y pattern between Prudhoe Bay and the Mackenzie delta in the north, and the start of the Foothills System at Caroline in central Alberta. The estimated cost of the line is about $US 6 billion, using a 36-inch diameter line at increased pressures in place of the 56-inch diameter pipe used in the 1970s. Construction plans are similar for the rest of the big Y, the Dempster Lateral beside the Dempster Highway between Whitehorse and Inuvik. A competing project, the Northern Gas Pipeline Project is also discussed. This line would run east of Prudhoe Bay under the Beaufort Sea to the Mackenzie Delta; then south along the Mackenzie Valley to Alberta. Cost of this line is also estimated at $US 6 billion, however, it would have a capacity of four billion cubic feet per day, including 2.5 billion cubic feet from Alaska and 1.5 billion cubic feet from Canada. Strong revival of interest is also reported from the supply side, with BP Amoco, ARCO, Chevron Canada Resources, Ranger 0il Ltd., Paramount Resources, Berkley Petroleum Corporation, Canadian Forest Oil, Alberta Energy Company, Petro-Canada, Anderson Resources, and Poco Petroleum Ltd., all showing interest to mount new

Reasons for decision in the matter of TransCanada PipeLines Limited and TransCanada Keystone Pipeline GP Ltd. : application dated 5 June 2006 for leave to transfer pipeline facilities and for a determination of the transfer price

International Nuclear Information System (INIS)

2007-01-01

TransCanada Pipelines Limited and its fully owned subsidiary TransCanada Keystone Pipeline GP Ltd. applied to the National Energy Board in June 2006 for leave to transfer certain pipeline facilities comprising part of TransCanada's mainline natural gas transmission system from TransCanada to Keystone for use in Keystone's proposed new oil pipeline. The transfer would involve the conversion of the facilities from gas service to oil service for use in the Keystone Project. The new oil pipeline would extend from Hardisty Alberta to Wood River and Patoka, Illinois. It would initially provide access for western Canada crude oil producers to the southern Petroleum Administration Defence District (PADD) 2 region of the United states. This is a major refining area which presently has minimal access for western Canada crude oil because of the limited pipeline capacity into the region. The Board held a hearing process to seek the views of interested parties regarding the list of issues that should be considered in dealing with the application. The list of issues included arguments of the Communications, Energy and Paperworkers Union of Canada (CEP) regarding the Board's jurisdiction; regulatory standards; energy supply markets and pipelines; potential impacts of the transfer such as potential costs to gas shippers and the impact of the transfer on mainline operations; and, the transfer at net book value (NBV). This document presented the Board's views on the transfer and the public interest. After considering all factors, the Board approved the sale and purchase of the Facilities from TransCanada to Keystone. The Board further ordered that TransCanada may reduce the mainline rate base by the NBV of the facilities upon their transfer to Keystone, and that Keystone may include the NBV in its pipeline oil plant upon the transfer of the facilities. 5 tabs., 14 figs., 6 appendices

The goal of this record of study is to examine the major facets involved in managing several petroleum service projects located in three different countries in the Gulf of Guinea simultaneously, while effectively engaging in business development activities for the Oil and Industrial Services Group (OIS). This work also furnishes adequate background on related subject matters to enable understanding of the projects presented. The petroleum services sector is the back bone of the oil and gas industry. Services companies are vital to the success of all petroleum and energy producers in the USA, the Gulf of Guinea and the world. There is a need and demand for these service companies because they play various roles such as logistics, drilling, construction, dredging, pipe laying, procurement, food supply, human resource supply, etc. The Gulf of Guinea comprises of countries from west and central Africa. This project was limited to Nigeria, Equatorial Guinea and Cameroon. This area holds the largest petroleum reserves in Africa and plays a vital role in the global supply of petroleum. The Oil and Industrial Services Group (OIS), plans to establish herself as one of the leading petroleum service companies in this gulf. To manage this expansion, I have taken the role of Gulf of Guinea manager to apply my background as a petroleum engineer as well as my business skills to build a successful division of the company. This work provides a record of study of the management of services, projects and contracts carried out by the OIS group in the gulf of Guinea. The following are the specific projects in the Gulf of Guinea that I participated in: Managing delivering, maintenance and marketing of offshore vessels, Offshore pipe laying project, Integrated pipeline maintenance project, Development a petroleum technical training facilities, Agbami pipe insulation project, Engineering lift project and Capital budgeting analysis for potential investments.

The vulnerability of oil collection pipelines to corrosion under conditions of stratified oil-water emulsion

Energy Technology Data Exchange (ETDEWEB)

Marichev, F N; Chernobay, L A; Teterina, O P; Yarmizin, V G

1980-01-01

Problems with oil industry equipment and pipeline corrosion have recently highlighted the problems of increased water content in oil and the presence of biogenic hydrogen sulphide in petroleum matter. These findings underscore the importance of taking these problems into consideration when formulating long-term production plans. A study of pipeline corrosion and its causes, as well as other factors, has permitted researchers to correlate hydrodynamic parameters for gas-fluid transportability and structural contour flows. The water phase simultaneously carries corrosion-active ions of dissolved hydrogen sulphide and material which interact to corrode metal in the lower sections of pipelines. In order to determine the susceptibility of pipelines to corrosion, it is necessary to establish the presence of stratified fluids in oil and water as well as the gas-fluid flow. Analysis has shown that those sections with stratified emulsion could be identified and that it is necessary to disclose the pipeline's ability to withstand such conditions. The proper selection of transport parameters permits the technological protection of the oil collection pipelines. Partially as a result of the increased flow speed guaranteeing an emulsion flow regime for the gas-water-oil flow, it was found that the operational service-life of pipelines could be prolonged by a reduction of corrosion in oil collection pipelines.

In the late 1970s, a leaking underground pipeline released petroleum hydrocarbons to a shallow, water-table aquifer in Kansas. Approximately six acres surrounding the release contain hydrocarbons at residual saturation. Parts of the release have acclimated and are carrying out anaerobic biodegradation of benzene, toluene, and the xylenes, Analysis of ground water from monitoring wells in areas that have acclimated reveal high concentrations of methane, less than -.1/liter oxygen, millimolar concentrations of acetate, and strongly reducing redox potentials. There is also a marked shift in the radio of the concentration of individual compounds to the total concentration of petroleum hydrocarbons

2014-04-01

Full Text Available The industrial revolution of the past century has resulted in significant damage to environmental resources such as air, water and soil. Petroleum contamination of soil is a serious problem throughout the oil producer countries. Remediation of petroleum contamination of soils is generally a slow and expensive process. Phytoremediation is a potentially less-damaging, cost-effective, but needs longer-term for remediation of contaminated land compared to the alternative methods. In this study the kinetics of petroleum hydrocarbon contaminated soils in Khozestan were investigated. For this paper Ryegrass (Lolium perenne plant selected and the decline of total petroleum hydrocarbon (TPH was analyzed after growth stage, every 10 days up to 90 days. The results of TPH concentration was fitted with zero-order kinetic, first-order kinetic and Higuchi model. The result indicated that degradation of TPH with presence of plants as a function of time was well fitted with the first-order kinetic model. The first-order rate constants (K and half-lives (T1/2 for TPH degradation were 0.0098 1/day and 71 day; respectively. The results of phytoremediation showed that there were 65% decreases in TPH concentration with Ryegrass during the 17 weeks.

Historical analysis of US pipeline accidents triggered by natural hazards

Natural hazards, such as earthquakes, floods, landslides, or lightning, can initiate accidents in oil and gas pipelines with potentially major consequences on the population or the environment due to toxic releases, fires and explosions. Accidents of this type are also referred to as Natech events. Many major accidents highlight the risk associated with natural-hazard impact on pipelines transporting dangerous substances. For instance, in the USA in 1994, flooding of the San Jacinto River caused the rupture of 8 and the undermining of 29 pipelines by the floodwaters. About 5.5 million litres of petroleum and related products were spilled into the river and ignited. As a results, 547 people were injured and significant environmental damage occurred. Post-incident analysis is a valuable tool for better understanding the causes, dynamics and impacts of pipeline Natech accidents in support of future accident prevention and mitigation. Therefore, data on onshore hazardous-liquid pipeline accidents collected by the US Pipeline and Hazardous Materials Safety Administration (PHMSA) was analysed. For this purpose, a database-driven incident data analysis system was developed to aid the rapid review and categorization of PHMSA incident reports. Using an automated data-mining process followed by a peer review of the incident records and supported by natural hazard databases and external information sources, the pipeline Natechs were identified. As a by-product of the data-collection process, the database now includes over 800,000 incidents from all causes in industrial and transportation activities, which are automatically classified in the same way as the PHMSA record. This presentation describes the data collection and reviewing steps conducted during the study, provides information on the developed database and data analysis tools, and reports the findings of a statistical analysis of the identified hazardous liquid pipeline incidents in terms of accident dynamics and

Using underground mine Karst water to solve water supply problem in underground mine

Wang, W. [Wanbei Mining Administration (China). Liuqiao No. 2 Mine

1995-05-01

There is a very rich karst water resource under the Liuqiao No. 2 underground mine. Under normal mining conditions the drainage is 546 m{sup 3}/h while the maximum drainage is up to 819 m{sup 3}/h. If water inrush occurred from a broken zone of a fault or a sinkhole of the karst, the flow could be up to 3269 m{sup 3}/h. The karst water is of good quality and high in pressure. The water head pressure at -400 m level is about 3.5 MPa. To save mine construction cost, it was decided that the water supply for coal production equipment, mining operation and mine fire control was to be changed from the surface to the underground by drilling a water well to tap the karst water resource. A water well with a depth of 63.3 m was drilled in the -400 m transportation roadway. The diameter of the well is 127 mm and it has a casing pipe with a diameter of 108 mm which is connected to the water supply pipeline. The pressure of the water supply is measured at 23.5 MPa and the water flow rate is 252 m{sup 3}/h. The establishment of the water supply system has achieved great cost saving for Liuqiao No. 2 Mine. 2 figs.

Coates, P.A.

1991-01-01

The Trans-Alaska Pipeline was the object of perhaps the most passionately fought conservation battle in the U.S. Although numerous authors documented the pipeline construction during its construction, there is, surprisingly, no previous scholarly treatment of this event written by an historian. Coates is an environmental historian who views the most interesting aspect of the controversy to be open-quote its relationship to earlier engineering projects and technological innovations in Alaska and the debates that accompanied them.close quotes Thus, he describes how the conservationist and environmental ideas arose during numerous earlier major Alaskan projects and controversies, including the Alaska Highway (1938-41), Canol Pipeline (1943-45), exploration of Naval Petroleum Reserve Number Four (Pet 4, 1944-1953), DEWline (1953-57), oil development in the Kenai National Moose Range (1957-58), statehood (1958), the creation of the Arctic Wildlife Refuge (1960), Project Chariot (1958-63), and Rampart Dam (1959-67). The history starts with the acquisition of Alaska in 1867 and finishes about the time of the Valdez oil spill in 1989

Underground or aboveground storage tanks - A critical decision

International Nuclear Information System (INIS)

Rizzo, J.A.

1992-01-01

With the 1988 promulgation of the comprehensive Resource Conservation and Recovery Act (RCRA) regulations for underground storage of petroleum and hazardous substances, many existing underground storage tank (UST) owners have been considering making the move to aboveground storage. While on the surface, this may appear to be the cure-all to avoiding the underground leakage dilemma, there are many other new and different issues to consider with aboveground storage. The greatest misconception is that by storing materials above ground, there is no risk of subsurface environmental problems. It should be noted that with the aboveground storage tank (AGST) systems, there is still considerable risk of environmental contamination, either by the failure of onground tank bottoms or the spillage of product onto the ground surface where it subsequently finds its way to the ground water. In addition, there are added safety concerns that must be addressed. The greatest interest in AGSTs comes from managers with small volumes of used oil, fresh oil, solvents, chemicals, or heating oil. Dealing with small capacity tanks is not so different than large bulk storage - and, in fact, it lends itself to more options, such as portable storage, tank within tank configurations and inside installations. So what are the other specific areas of concern besides environmental to be addressed when making the decision between underground and aboveground tanks? The primary issues that will be addressed in this presentation are: (1) safety; (2) product losses; (3) cost comparison of USTs vs AGSTs; (4) space availability/accessibility; (5) precipitation handling; (6) aesthetics and security; (7) pending and existing regulations

A key advantage of trenchless construction methods compared with traditional open-cut methods is their ability to install or rehabilitate underground utility systems with limited disruption to the surrounding built and natural environments. The equivalent monetary values of these disruptions are commonly called social costs. Social costs are often ignored by engineers or project managers during project planning and design phases, partially because they cannot be calculated using standard estimating methods. In recent years some approaches for estimating social costs were presented. Nevertheless, the cost data needed for validation of these estimating methods is lacking. Development of such social cost databases can be accomplished by compiling relevant information reported in various case histories. This paper identifies eight most important social cost categories, presents mathematical methods for calculating them, and summarizes the social cost impacts for two pipeline construction projects. The case histories are analyzed in order to identify trends for the various social cost categories. The effectiveness of the methods used to estimate these values is also discussed. These findings are valuable for pipeline infrastructure engineers making renewal technology selection decisions by providing a more accurate process for the assessment of social costs and impacts. - Highlights: • Identified the eight most important social cost factors for pipeline construction • Presented mathematical methods for calculating those social cost factors • Summarized social cost impacts for two pipeline construction projects • Analyzed those projects to identify trends for the social cost factors.

Zhang, Limao; Wu, Xianguo; Qin, Yawei; Skibniewski, Miroslaw J; Liu, Wenli

2016-02-01

Tunneling excavation is bound to produce significant disturbances to surrounding environments, and the tunnel-induced damage to adjacent underground buried pipelines is of considerable importance for geotechnical practice. A fuzzy Bayesian networks (FBNs) based approach for safety risk analysis is developed in this article with detailed step-by-step procedures, consisting of risk mechanism analysis, the FBN model establishment, fuzzification, FBN-based inference, defuzzification, and decision making. In accordance with the failure mechanism analysis, a tunnel-induced pipeline damage model is proposed to reveal the cause-effect relationships between the pipeline damage and its influential variables. In terms of the fuzzification process, an expert confidence indicator is proposed to reveal the reliability of the data when determining the fuzzy probability of occurrence of basic events, with both the judgment ability level and the subjectivity reliability level taken into account. By means of the fuzzy Bayesian inference, the approach proposed in this article is capable of calculating the probability distribution of potential safety risks and identifying the most likely potential causes of accidents under both prior knowledge and given evidence circumstances. A case concerning the safety analysis of underground buried pipelines adjacent to the construction of the Wuhan Yangtze River Tunnel is presented. The results demonstrate the feasibility of the proposed FBN approach and its application potential. The proposed approach can be used as a decision tool to provide support for safety assurance and management in tunnel construction, and thus increase the likelihood of a successful project in a complex project environment. © 2015 Society for Risk Analysis.

Mackenzie Valley Pipeline market demand, supply, and infrastructure analysis : final report

International Nuclear Information System (INIS)

2004-01-01

Mackenzie Valley Pipeline Co-Venturers is a consortium of petroleum companies proposing to construct a 1,400 km long, large-diameter, high-pressure natural gas transmission pipeline from the northwestern edge of the Northwest Territories to the Alberta-Northwest Territories border. The Mackenzie Valley Pipeline will bring natural gas from the Mackenzie Delta region to markets in Alberta, central and eastern Canada and the United States. Navigant Consulting Ltd. prepared this assessment of the long-term market need for natural gas produced from the Mackenzie Delta. It presents an analysis of gas demand, supply and infrastructure. Three sensitivity cases were examined, incorporating different assumptions about the initial capacity of the pipeline, potential expansion of its capacity and different levels of gas demand in Canada and the United States. The report indicates that gas markets in North America support construction of the proposed 34 million cubic metre per day pipeline in the 2009 timeframe, with possible expansion in 2015 and 2020. It also indicates that there will be enough capacity on the intra-Alberta gas transmission system to accommodate the projected deliveries of Mackenzie Delta gas. The increase in gas demand is due to an increase in residential and commercial gas consumption, electric power generation and the energy intensive bitumen extraction and processing activities in the Alberta oil sands industry. 36 tabs., 56 figs

Alternative designs for petroleum product storage tanks for groundwater protection.

Science.gov (United States)

Oke Adeleke, Samson

In developing countries, there are numerous occurrences of petroleum product spillage in groundwater. The current practice of burying storage tanks beneath the surface without adequate safety devices facilitates this phenomenon. Underground tanks rust and leak, and spilled petroleum products migrate downward. The movement of the oil in the soil depends on its viscosity and quantity, the permeability of the soil/rock, and the presence of fractures within the rock. The oil spreads laterally in the form of a thin pancake due to its lower specific gravity, and soluble components dissolve in water. The pollution plume of petroleum products and dissolved phases moves in the direction of groundwater flow in the aquifer within the pores of soil and sediments or along fractures in basement complex areas. Most communities reply heavily on groundwater for potable and industrial supplies. However, the sustainability of this resource is under threat in areas where there are filling stations as a result of significant groundwater contamination from petroleum product spillage. Drinking water becomes unpalatable when it contains petroleum products in low concentrations, and small quantities may contaminate large volumes of water. Considering the losses incurred from spillage, the cost of cleaning the aquifer, and the fact that total cleansing and attenuation is impossible, the need to prevent spillage and if it happens to prevent it from getting into the groundwater system is of paramount importance. This paper proposes alternative design procedures with a view to achieving these objectives.

Analysis of oil-pipeline distribution of multiple products subject to delivery time-windows

Science.gov (United States)

Jittamai, Phongchai

This dissertation defines the operational problems of, and develops solution methodologies for, a distribution of multiple products into oil pipeline subject to delivery time-windows constraints. A multiple-product oil pipeline is a pipeline system composing of pipes, pumps, valves and storage facilities used to transport different types of liquids. Typically, products delivered by pipelines are petroleum of different grades moving either from production facilities to refineries or from refineries to distributors. Time-windows, which are generally used in logistics and scheduling areas, are incorporated in this study. The distribution of multiple products into oil pipeline subject to delivery time-windows is modeled as multicommodity network flow structure and mathematically formulated. The main focus of this dissertation is the investigation of operating issues and problem complexity of single-source pipeline problems and also providing solution methodology to compute input schedule that yields minimum total time violation from due delivery time-windows. The problem is proved to be NP-complete. The heuristic approach, a reversed-flow algorithm, is developed based on pipeline flow reversibility to compute input schedule for the pipeline problem. This algorithm is implemented in no longer than O(T·E) time. This dissertation also extends the study to examine some operating attributes and problem complexity of multiple-source pipelines. The multiple-source pipeline problem is also NP-complete. A heuristic algorithm modified from the one used in single-source pipeline problems is introduced. This algorithm can also be implemented in no longer than O(T·E) time. Computational results are presented for both methodologies on randomly generated problem sets. The computational experience indicates that reversed-flow algorithms provide good solutions in comparison with the optimal solutions. Only 25% of the problems tested were more than 30% greater than optimal values and

India′s energy situation is characterized by increasing energy demand, high fossil fuel dependency, large import shares, and significant portion of population deprived of modern energy services. At this juncture, natural gas, being the cleanest fossil fuel with high efficiency and cost effectiveness, is expected to play an important role. India, with only 0.6% of proven world reserves, is not endowed with adequate natural gas domestically. Nevertheless, there are gas reserves in neighbouring regions which gives rise to the prospects of three cross border gas pipeline projects, namely, Iran–Pakistan–India, Turkmenistan–Afghanistan–Pakistan–India, and Myanmar–Bangladesh–India. This study is a political analysis of these pipeline projects. First, it provides justification on use of natural gas and promotion of cross border energy trade. Then it examines these three pipeline projects and analyses the security concerns, role of different actors, their positions, shifting goals, and strategies. The study develops scenarios on the basis of changing circumstances and discusses some of the pertinent issues like technology options for underground/underwater pipelines and role of private players. It also explores impact of India′s broader foreign relations and role of SAARC on the future of pipelines and proposes energy induced mutually assured protection (MAP) as a concept for regional security. -- Highlights: •We justify the need for cross border energy trade through gas pipelines for India. •We examine prospective pipeline projects—IPI, TAPI, MBI and their security issues. •We develop scenarios and analyze role of actors, their positions, and strategies. •We discuss technology and policy options for realizing these gas pipelines. •We propose energy induced mutually assured protection (MAP) for regional security

Environmental and safety factors associated with such operations were also examined. A separate abstract was prepared for each of the presented papers. Refs, figs and tabs

Facts 2002. The Norwegian petroleum sector

The petroleum sector is highly significant for the Norwegian economy. Its share of gross domestic product, exports and total government revenues has been substantial over the past two decades, reaching a particularly high level in 2000 and 2001. The principal reason why revenues were so high in these two years is a combination of high oil prices, a strong USD against the NOK and historically high petroleum production. The share of petroleum investment in total capital spending in the Norwegian economy was at its highest in the early 1990s. Total investment in the petroleum sector has been above NOK 40 bn every year since 1992, and peaked in 1998 at roughly NOK 80 bn. Capital spending declined to around NOK 56.9 bn in 2001. The government's most important revenue sources in recent years have been cash flow from the state's direct financial interest (SDFI) and from taxes. Production of crude oil has averaged around three mill barrels per day since 1996. The figure for 2001 was 3.1 mill barrels. Including natural gas liquids (NGL) and condensate raises the 2001 average to 3.4 mill barrels oe per day. At 53 mill scm oe, gas production was also high in 2001. Oil production is expected to remain more or less unchanged over the next few years, and then to go into a gradual decline. Gas output, on the other hand, should expand substantially over the coming decade and is expected to be increasingly significant in Norwegian petroleum output in future. The petroleum sector is also a substantial player internationally. Norway ranks as the world's sixth largest producer and third largest net exporter of oil. It is also the world's third largest exporter of pipeline gas, and Norwegian foreign sales of this commodity accounted for about two per cent of global consumption in 2001. Roughly 10 per cent of west European gas consumption is covered from Norway. Several changes were made to state participation in the petroleum sector during 2001.

Full text : For increase of ecological safety of the pipeline, necessary decrease of damage (risk) rendered by the pipeline on surrounding natural environment which depends: on the frequency of damage of the pipeline; on the volume poured oil; on the factor of sensitivity of an environment where flood of oil was. Frequency of damage of the pipeline depends on physico-chemical properties of a material of the pipeline, from its technical characteristics (thickness of a wall, length of a pipe, working pressure), on the seismic area of the district where the pipeline passed and also on the way of lining of the pipeline (underground or overground). The volume poured oil depends on diameter of the received damage, from stability of the pipeline mechanical and other external actions, from an ambient temperature, from capacity of the pipeline, from distance between the latches established in the pipeline, and also from time, necessary for their full closing. The factor of sensitivity of environment depends on geological structure and landscapes of district (mountain, the river, settlements) where passed the pipeline. At designing the pipeline, in report is shown questions of increase of ecological safety of the pipeline are considered at his construction and exploitation. For improvement of ecological safety of the pipeline is necessary to hold the following actions: Ecological education of the public, living near along a line of the oil pipeline; carrying out ecological monitoring; working of the public plan of response to oil spills; For ecological education of the public is necessary: carrying out informing of the public for all (technical, ecological, social and economic and legal) questions connected to an oil pipeline, and also on methods of protection of the rights at participation in acceptance of ecological significant decisions; Creation of public groups for realization of activity on observance of the legislation and to prevention of risks; Exposure of hot

Uncertainties in pipeline water percentage measurement

Energy Technology Data Exchange (ETDEWEB)

Scott, Bentley N.

2005-07-01

Measurement of the quantity, density, average temperature and water percentage in petroleum pipelines has been an issue of prime importance. The methods of measurement have been investigated and have seen continued improvement over the years. Questions are being asked as to the reliability of the measurement of water in the oil through sampling systems originally designed and tested for a narrow range of densities. Today most facilities sampling systems handle vastly increased ranges of density and types of crude oils. Issues of pipeline integrity, product loss and production balances are placing further demands on the issues of accurate measurement. Water percentage is one area that has not received the attention necessary to understand the many factors involved in making a reliable measurement. A previous paper1 discussed the issues of uncertainty of the measurement from a statistical perspective. This paper will outline many of the issues of where the errors lie in the manual and automatic methods in use today. A routine to use the data collected by the analyzers in the on line system for validation of the measurements will be described. (author) (tk)

1994-09-01

The Underground Storage Tank (UST) Management Program at the Oak Ridge Y-12 Plant was established to locate UST systems in operation at the facility, to ensure that all operating UST systems are free of leaks, and to establish a program for the removal of unnecessary UST systems and upgrade of UST systems that continue to be needed. The program implements an integrated approach to the management of UST systems, with each system evaluated against the same requirements and regulations. A common approach is employed, in accordance with Tennessee Department of Environment and Conservation (TDEC) regulations and guidance, when corrective action is mandated. This Management Plan outlines the compliance issues that must be addressed by the UST Management Program, reviews the current UST inventory and compliance approach, and presents the status and planned activities associated with each UST system. The UST Management Plan provides guidance for implementing TDEC regulations and guidelines for petroleum UST systems. (There are no underground radioactive waste UST systems located at Y-12.) The plan is divided into four major sections: (1) regulatory requirements, (2) implementation requirements, (3) Y-12 Plant UST Program inventory sites, and (4) UST waste management practices. These sections describe in detail the applicable regulatory drivers, the UST sites addressed under the Management Program, and the procedures and guidance used for compliance with applicable regulations.

Coaxial Sensors For Broad-Band Complex Permittivity Measurements of Petroleum Fluids

Energy Technology Data Exchange (ETDEWEB)

Folgeroe, K.

1996-12-31

This doctoral thesis verifies that dielectric spectroscopy and microwave permittivity measurements can be used to characterize petroleum liquids. It concentrates on developing sensors for three potential industrial applications: quality characterization of crude oil and petroleum fractions, monitoring of gas-hydrate formation in water-in-oil emulsions, and determination of water-content in thin liquid layers. The development of a permittivity measurement system for crude oil and petroleum fractions is described. As black oils have low dielectric constant and loss, the system must be very sensitive in order to measure the dielectric spectra and to distinguish oils of different permittivity. Such a system was achieved by combining impedance and scattering parameter measurements with appropriate permittivity calculation methods. The frequency range from 10 kHz to 6 GHz was found convenient for observing the main dispersion of the oils. All the oils had dielectric constants between 2.1 and 2.9 and dielectric loss below 0.01. The oils studied were samples of the feedstock for the cracker and coke processes at a petroleum refinery. This verifies that dielectric spectroscopy is a potential technique for on-line quality monitoring of the feedstock at petroleum refineries. Gas hydrates may cause major problems like clogging of pipelines. Dielectric spectroscopy is proposed as a means of monitoring the formation of gas hydrates in emulsions. It is found that open-ended coaxial probes fulfill the sensitivity requirements for such sensors. 312 refs., 87 figs., 20 tabs.

Review of the Factors that Influence the Condition of Wax Deposition in Subsea Pipelines

Directory of Open Access Journals (Sweden)

Koh Junyi

2018-03-01

Full Text Available When crude oil is transported via sub-sea pipeline, the temperature of the pipeline decreases at a deep depth which causes a difference in temperature with the crude oil inside. This causes the crude oil to dissipate its heat to the surrounding until thermal equilibrium is achieved. This is also known as the cloud point where wax begins to precipitate and solidifies at the walls of the pipeline which obstruct the flow of fluid. The main objective of this review is to quantify the factors that influence wax deposition such as temperature difference between the wall of the pipeline and the fluid flowing within, the flow rate of the fluid in the pipeline and residence time of the fluid in the pipeline. It is found the main factor that causes wax deposition in the pipeline is the difference in temperature between the petroleum pipeline and the fluid flowing within. Most Literature deduces that decreasing temperature difference results in lower wax content deposited on the wall of the pipeline. The wax content increases with rising flow rate. As for the residence time, the amount of deposited wax initially increases when residence time increases until it reaches a peak value and gradually decreases. Flow-loop system and cold finger apparatus were used in literature investigations to determine the trends above. Three new models are generated through a regression analysis based on the results from other authors. These new models form a relationship between temperature difference, flow rate, residence time and Reynolds number with wax deposition. These models have high values of R-square and adjusted R-square which demonstrate the reliability of these models.

The paucity of information in the literature on the characteristics of plants that could be used for phytoremediation of petroleum hydrocarbons (PHC)-contaminated sites was the principal reason for this study. The aim of the study was to identify indigenous plants growing in PHC-impacted soil in Umuahia in eastern-Nigeria that have the ability to phytoremediate soils contaminated with hydrocarbons under tropical monsoon climate conditions. A total of 28 native plant species from different families growing in and around hydrocarbon-impacted soil in the vicinity of vandalized pipelines carrying petroleum products were collected and studied for their ability to grow in a hydrocarbon-impacted soil and remove the PHC from the impacted soil. Some of the plants demonstrated the ability to grow in soil with high levels of the total petroleum hydrocarbons (TPH), which shows that they may be tolerant to hydrocarbons in soil and could potentially phytoremediate a hydrocarbon-contaminated soil. Chromolaena odorata, Aspilia africana, Chloris barbata, Pasparlum vaginatum, Bryophyllum pinnatum, Paspalum scrobiculatum, Cosmos bipinnatus, Eragrostis atrovirens, Cyperus rotundus, and Uvaria chamae showed tendencies to phytoremediate contaminated soil. By using bioaccumulation coefficient (BAC) as a measure of phytoremediation, results showed that C. odorata, A. africana, and U. chamae demonstrated the highest potentials to phytodegrade hydrocarbons in soil.

The twenty-eight double-shell underground radioactive waste storage tanks at the U. S. Department of Energy's Hanford Site near Richland, WA are interconnected by the Waste Transfer System network of buried steel encased pipelines and pipe jumpers in below-grade pits. The pipeline material is stainless steel or carbon steel in 51 mm to 152 mm (2 in. to 6 in.) sizes. The pipelines carry slurries ranging up to 20 volume percent solids and supernatants with less than one volume percent solids at velocities necessary to prevent settling. The pipelines, installed between 1976 and 2011, were originally intended to last until the 2028 completion of the double-shell tank storage mission. The mission has been subsequently extended. In 2010 the Tank Operating Contractor began a systematic evaluation of the Waste Transfer System pipeline conditions applying guidelines from API 579-1/ASME FFS-1 (2007), Fitness-For-Service. Between 2010 and 2014 Fitness-for-Service examinations of the Waste Transfer System pipeline materials, sizes, and components were completed. In parallel, waste throughput histories were prepared allowing side-by-side pipeline wall thinning rate comparisons between carbon and stainless steel, slurries and supernatants and throughput volumes. The work showed that for transfer volumes up to 6.1E+05 m"3 (161 million gallons), the highest throughput of any pipeline segment examined, there has been no detectable wall thinning in either stainless or carbon steel pipeline material regardless of waste fluid characteristics or throughput. The paper describes the field and laboratory evaluation methods used for the Fitness-for-Service examinations, the results of the examinations, and the data reduction methodologies used to support Hanford Waste Transfer System pipeline wall thinning conclusions.

Overview of interstate hydrogen pipeline systems

2008-01-01

The use of hydrogen in the energy sector of the United States is projected to increase significantly in the future. Current uses are predominantly in the petroleum refining sector, with hydrogen also being used in the manufacture of chemicals and other specialized products. Growth in hydrogen consumption is likely to appear in the refining sector, where greater quantities of hydrogen will be required as the quality of the raw crude decreases, and in the mining and processing of tar sands and other energy resources that are not currently used at a significant level. Furthermore, the use of hydrogen as a transportation fuel has been proposed both by automobile manufacturers and the federal government. Assuming that the use of hydrogen will significantly increase in the future, there would be a corresponding need to transport this material. A variety of production technologies are available for making hydrogen, and there are equally varied raw materials. Potential raw materials include natural gas, coal, nuclear fuel, and renewables such as solar, wind, or wave energy. As these raw materials are not uniformly distributed throughout the United States, it would be necessary to transport either the raw materials or the hydrogen long distances to the appropriate markets. While hydrogen may be transported in a number of possible forms, pipelines currently appear to be the most economical means of moving it in large quantities over great distances. One means of controlling hydrogen pipeline costs is to use common rights-of-way (ROWs) whenever feasible. For that reason, information on hydrogen pipelines is the focus of this document. Many of the features of hydrogen pipelines are similar to those of natural gas pipelines. Furthermore, as hydrogen pipeline networks expand, many of the same construction and operating features of natural gas networks would be replicated. As a result, the description of hydrogen pipelines will be very similar to that of natural gas pipelines

Development of a database of multispectral satellite data from the Russian satellite RESURS-F, radar data from the Japanese satellite JERS-1, airborne radar data with different wavelengths, and aerial photographic data acquired since 1974 of the Timan-Pechorian petroleum province was discussed. The database also contains the data layers dealing with different aspects of the natural environment. It is planned to supplement the data with data from the RADARSAT Project. Rapture of a pipeline in October 1994 and other field and pipeline accidents have created significant changes in the landscape, hence the database is a useful tool for mapping these changes and to study the effects of oil pollution on the natural environment

Since September 2010, ArcelorMittal Monlevade has gained flexibility and an important opportunity to reduce the cost of its energy mix due to the arrival of the Natural Gas (NG) via Steel Valley Pipeline. The proposal of the project included the substitution of the Liquefied Petroleum Gas (LPG), Fuel Oil and Compressed Natural Gas for natural gas via pipeline. To support the investment decision, in addition to domestic economic and technical aspects, the macro economic environment concerning the NG was also taken into account. This paper shows the analysis for adjustment of internal equipment, the structure of the contract, the conceptual project of the gas distribution built inside the main events, the gains achieved, the alternatives for the acquisition of NG and operational flexibility of ArcelorMittal Monlevade in case of interruption of supply of natural gas.

Evaporation of petroleum products from contaminated soils

International Nuclear Information System (INIS)

Kang, S.H.

1996-01-01

Bioremediation can remove petroleum products from soil that has been contaminated by leaking underground storage tanks, but abiotic processes such as evaporation can contribute significantly to the overall removal process. The mathematical model described in this paper was developed to predict the evaporation rate of volatile liquids from petroleum-contaminated sand. The model is based on simple concepts relating to molecular diffusion embodied in the theory underlying the estimation of binary diffusivities using measurements made with an Arnold diffusion cell. The model in its simplified form indicates that the rate of evaporation for a particular volatile liquid is proportional to the square root of the product of diffusivity and partial pressure divided by the molecular weight of the liquid. This in part explains why evaporative losses from sand are so much higher for gasoline than for diesel fuel. The model also shows that the time for evaporation is directly proportional to the square of the depth dried out and inversely proportional to the vapor pressure of the volatile liquid. The model was tested using gravimetric measurements of the evaporation of n-heptane, unleaded gasoline, and diesel fuel from sand under laboratory conditions

Spillover of hazardous materials from transport pipelines can lead to catastrophic events with serious and dangerous environmental impact, potential fire events and human fatalities. The problem is more serious for large pipelines when the construction material is under environmental corrosion conditions, as in the petroleum and gas industries. In this way, predictive models can provide a suitable framework for risk evaluation, maintenance policies and substitution procedure design that should be oriented to reduce increased hazards. This work proposes a bayesian probabilistic approach to identify and predict the type of failure (leakage or rupture) for steel pipelines under realistic corroding conditions. In the first step of the modeling process, the mechanical performance of the pipe is considered for establishing conditions under which either leakage or rupture failure can occur. In the second step, experimental burst tests are used to introduce a mean probabilistic boundary defining a region where the type of failure is uncertain. In the boundary vicinity, the failure discrimination is carried out with a probabilistic model where the events are considered as random variables. In turn, the model parameters are estimated with available experimental data and contrasted with a real catastrophic event, showing good discrimination capacity. The results are discussed in terms of policies oriented to inspection and maintenance of large-size pipelines in the oil and gas industry. 2010 Elsevier B.V. All rights reserved.

Health impact assessment (HIA) of projects, programmes and policies is increasingly recognized as a powerful methodology for mitigating negative health impacts and enhancing equitable and sustainable development, yet applications in the developing world are sparse. Here, we focus on a large infrastructure development in sub-Saharan Africa, namely the Chad-Cameroon petroleum development and pipeline project. We adapted a five-step process for HIA, consisting of (1) screening of project documents, (2) profiling of affected communities, (3) identifying priority health areas, predicting potential impacts, and proposing mitigation measures, (4) implementing interventions, and (5) monitoring and evaluation of health impacts. We found that project scoping was broad, including extensive environmental and social assessments. Innovative features of the project include the high degree of public-private partnerships, and the management of oil revenues for purposes of poverty reduction. The project also addressed occupational and public health issues, and developed and implemented measures to prevent or mitigate potential health impacts. However, there was a disproportionate emphasis on workers' health, particularly on the prevention/mitigation of construction-related injuries, sexually transmitted infections (STIs; mainly HIV/AIDS), and malaria. Health impacts among surrounding communities, and cumulative health impacts in the larger region were not considered in a comprehensive way. Concluding, there is a need for a more systemic approach to HIA and its incorporation within 'Equator Principles', which are increasingly adopted by the international financial community. This process would include clarification of corporate social responsibility beyond the project fence line in the mitigation of health problems at regional levels. Finally, we propose the establishment and running of a longitudinal demographic surveillance system, which--coupled with regular household surveys

Full Text Available Risk analysis pipelines in the quake as one of the most vital arteries in the current circumstances in the world is of special importance. in our everyday activities, used to underground structures such as pipes, tunnels, wells and so on for services such as transporting water, transportation, irrigation, drainage, sewage disposal, transporting oil and gas, carrying acid waste, industrial, household and so on. With regard to the huge investments structures, especially buried underground pipes, we need to study these constructs in response to the earthquake, is clearly felt. Pipelines used for transporting gas and other fluids, are widely distributed in all areas. These lines due to passing through the densely populated areas are always buried in the earth. Seismic behavior of these pipes as a result of the interaction between the soil and the pipe is different from the above-ground structures. The manner of modelling of the effects of soil liquefaction on the pipes in this thesis is that two shear springs and a normal spring is defined between soil and the pipe that in liquefaction mode minimize the friction shear strength.

Soil contaminated by virgin petroleum products leaking from underground storage tanks is a pervasive problem in the United States. Economically feasible disposal of such soil concerns the responsible party (RP), whether the RP is one individual small business owner, a group of owners, or a large multinational corporation. They may need a starting point in their search for an appropriate solution, such as recycling. The report provides initial assistance in two important areas. First it discusses four potential recycling technologies that manufacture marketable products from recycled petroleum-contaminated soil: the hot mix asphalt process, the cold mix asphalt system, cement production, and brick manufacturing. The report also presents the results of a project survey designed to identify recycling facilities. It lists recycling facilities alphabetically by location within each state, organized by U.S. Environmental Protection Agency (EPA) Region. The report also includes detailed addresses, recycling locations, telephone numbers, and contacts for these facilities. The scope of the project limits listings to fixed facilities or small mobile facility owners that recycle soil contaminated by virgin petroleum products into marketable commodities. It does not address site-specific or commercial hazardous waste remediation facilities

According to the existing prognoses more than 1 million km of gas pipelines, oil pipelines and water pipelines are built up to the year 2030. The predominant portion is from gas pipelines. The safe continued utilization of the aging pipelines is a large challenge. In addition, the diagnostic technology, the evaluation and risk assessment have to be developed further. With the design of new oil pipelines and gas pipelines, aspects of environmental protection, the energy efficiency of transport and thus the emission reduction of carbon dioxide, the public acceptance and the market strategy of the exporters gain in importance. With the offshore pipelines one soon will exceed the present border of 2,000 m depth of water and penetrate into larger sea depths.

Environmental issues of petroleum exploration and production: Introduction

Science.gov (United States)

Kharaka, Yousif K.; Dorsey, Nancy S.

2005-01-01

Energy is the lifeblood of our planet Earth, an essential commod- ity that powers the expanding global economy. Starting in the 1950s, oil and natural gas became the main sources of primary energy for the increasing world population, and this dominance is expected to continue for several more decades (Edwards, 1997; Energy Information Administration (EIA), 2004). In the United States, petroleum production started in 1859 when Drake's well was drilled near Titusville, Pennsylvania, and oil and natural gas currently supply approximately 63% of the energy consumption; forecasts indicate that by 2025, their use will increase by about 40% to 28.3 million bbl/day and to 31.4 tcf/yr (EIA, 2004). The clear benefits of petroleum consumption, however, can carry major environmental impacts that may be regional or global in scale, in- cluding air pollution, global climate change, and oil spills. This vol- ume of Environmental Geosciences, covering environmental impacts of petroleum exploration and production, does not address these major impacts directly because air pollution and global warming are issues related primarily to petroleum and coal uses, and major oil spills are generally attributed to marine petroleum transportation, such as the Exxon Valdez's 1989 spill of 260,000 bbl of oil into Prince William Sound, Alaska. Exploration for and production of petroleum, however, have caused local detrimental impacts to soils, surface and groundwa- ters, and ecosystems in the 36 producing states in the United States (Richter and Kreitler, 1993; Kharaka and Hanor, 2003). These im- pacts arose primarily from the improper disposal of some of the large volumes (presently estimated at 20 billion bbl/yr total pro- duced) of saline water produced with oil and gas, from accidental hydrocarbon and produced-water releases, and from abandoned oil wells that were orphaned or not correctly plugged (Kharaka et al., 1995; Veil et al., 2004).

Project's objective is to evaluate state-of-the-art methods for locating pipelines in shallow (less than 15 ft) water and for determining and monitoring their burial depths. The following recommendations are made on the research needed in three areas for locating near-shore, shallowly buried pipelines: (1) Sensors: The pipeline industry has selected the magnetic gradiometer array (GA) as a preferred sensor method. Other potential methods exist as backups. No additional research is recommended. (2) Remotely Operated Vehicles (ROVs): The Pipeline Research Committee is pursuing development of a prototype ROV is deliver the GA or other similar equipment to pipeline locations. (3) Phenomena: The data being collected from research on the phenomena affecting seabed conditions and the bathymetric data being collected along the Gulf Coast should be synthesized. This new effort should focus on identifying erosion-prone areas with respect to present and potential future pipeline locations. Technical approach is to get the broadest perspective on the concerns related to the determination of burial conditions for offshore pipelines, Argonne National Laboratory (ANL) contacted individuals and organizations from the gas and petroleum industries, hardware and software vendors, academicians, and representatives from the government. A literature survey yielded the names of persons within academia who are presently working on similar applications with sensors. In the oil and gas industry, individuals and organizations involved in the Pipeline Research Committee made extensive contributions to the review and also provided the names of meaningful contacts from among their vendors. Discussions were held with the various persons both on the telephone and face to face. Vendors provided background materials and overview presentations on their capabilities for ANL to review

Experimental research of joint influence of salinization and petroleum pollution on thermal capacity of frozen ground

International Nuclear Information System (INIS)

Motenko, R.G.

2010-01-01

Most gas and petroleum fields are located in permafrost zones, with some being on saline territories. Oil pollution of soils can occur in different ways and at different points such as during the extraction, processing and storage, and during transportation of oil and petroleum products. Oil producing pollution and salinization of soil often happen together. In this case, the sources of salts are the formation fluid, commercial waste water, the contents of the granaries and other geochemically active substances used for the extraction and desalting of crude oil. Joint salinization and contamination can also happen during the rupture of oil pipelines in saline areas. Although there is research available on the properties of saline soils and on properties of soils polluted with petroleum, there are no studies that describe changes of ground properties with joint pollution of salt and petroleum. This paper presented a study that examined the joint influence of salinization and petroleum pollution on the thermal characteristics of thawed and frozen grounds, particularly on thermal capacity. The paper outlined the purpose of the research and described the experimental methods. It was concluded that an increase of salinization increases the heat capacity of frozen soil because the amount of unfrozen water increases with increasing salinization. 10 refs., 5 figs.

Reasons for decision in the matter of Maritimes and Northeast Pipeline Management Ltd

International Nuclear Information System (INIS)

2000-01-01

Maritimes and Northeast Pipeline Management Ltd. (M and NP) applied to the National Energy Board (NEB) for final tolls effective 1 December 1999 for the lateral natural gas pipeline from their mainline to Point Tupper, Nova Scotia. The application covered a ten-month test period. The initial application included the costs and volumes associated with the mainline and the Point Tupper lateral pipeline but was subsequently amended to remove the Point Tupper Lateral costs and volumes because it was doubtful that the lateral would be in service during the test period. The mainline went into service on 1 December 1999 and gas first flowed to market on 31 December 1999. This report presented the revenue requirements authorized by the NEB for the test period and summarized the applied-for rate base and the approved rate base for the test period. It also provided a detailed account of mainline construction costs, including project cost estimates, master construction agreement, governance and compensation structure, and incentive compensation plans. The applicant, M and NP, believes that the NEB should make its judgement according to the applied-for costs and not on the accuracy of the previous cost estimates. This report also presented the opposing views of the intervenors regarding just and reasonable tolls. The intervenors included the Canadian Association of Petroleum Producers, the East Coast Producer Group, Shell, the province of New Brunswick, the Nova Scotia Petroleum Directorate and the NEB. The Board has made several decisions, many in favor of M and NP regarding rate base, debt financing costs, rate of return on rate base, operating and maintenance costs, deferral accounts, deferral of toll hearing costs, disposition of account balances and carrying charges, and tariff matters. The final 8 orders of the NEB were listed in Appendix 1 of this report as Order TG-5-2000. 3 tabs., 3 appendices

Analysis of a buried pipeline at WWER-440/213 Paks NPP

International Nuclear Information System (INIS)

1999-01-01

According to regulations, all safety structures of a NPP must be designed to withstand loads induced by earthquakes. This applies to safety related underground piping systems. These structures are typically embedded in about 2-3 m of layered soil, and sometimes protected by concrete slabs resting on the ground surface. A rigorous solution for the dynamic response of such a structure would require accounting for nonlinear and three dimensional effects. A non-linear analysis is possible by using specialized computer codes and material models to account for non-linear behaviour of the soil. The aim of this paper was to reanalyze the pipeline of Paks NPP in order to demonstrate its dynamic behaviour interacting with the soil and the connected buildings as well as to determine the dynamic responses and the stresses in typical regions of the pipeline. To perform the numerical analysis a three dimensional finite element code (SSASSI/S) based on 'flexible volume method' was applied

A mathematical model for leak location and leak area determination in pipeline networks

Directory of Open Access Journals (Sweden)

Oyedokun O.I.

2013-01-01

Full Text Available Prompt leak location and leak area determination in oil and gas pipeline installations is an indispensable approach to controlling petroleum products wastages in pipes. However, there is an evident lack of literature information on this subject. In this paper, we modelled leak location detection and leak area determination in pipes by applying two methodologies and gave an illustrative example using simulated data with the aid of Matlab. A comparison of these two approaches resulted in an error of 6.24%, suggesting that the closer the leak is to the measurement station, the lower will be the time interval between two successive waves that will pass through the leak and get to the measurement station. The relationship between the pipe area and coefficient of reflection is parabolic. This contribution is valuable to pipeline engineers in the economic control of leaks.

In order to study adaptation of microalgae to petroleum contamination, we have examined an environmental stress gradient by crude oil contamination in the Arroyo Minero River (AMR), Argentina. Underground crude oil has constantly leaked out since 1915 as a consequence of test drilling for possible petroleum exploitation. Numerous microalgae species proliferated in AMR upstream of the crude oil spill. In contrast, only four microalgal species were detected in the crude oil spill area. Species richness increases again downstream. Microalgae biomass in the crude oil spill area is dominated by a mesophile species, Scenedesmus sp. Effects of oil samples from AMR spill on photosynthetic performance and growth were studied using laboratory cultures of two Scenedesmus sp. strains. One strain (Se-co) was isolated from the crude oil spill area. The other strain (Se-pr) was isolated from a pristine area without petroleum contamination. Crude oil has undetectable effects on Se-co strain. In contrast crude oil rapidly destroys Se-pr strain. However, Se-pr strain can adapt to low doses of petroleum ({<=}3% v/v total hydrocarbons/water) by means of physiological acclimatization. In contrast, only rare crude oil-resistant mutants are able to grow under high levels of crude oil ({>=}10% v/v total hydrocarbons/water). These crude oil-resistant mutants have arisen through rare spontaneous mutations that occur prior to crude oil exposure. Species richness in different areas of AMR is closely connected to the kind of mechanism (genetic adaptation vs. physiological acclimatization) that allows adaptation. Resistant-mutants are enough to assure the survival of microalgal species under catastrophic crude oil spill.

The increasing complexity in specifying the quality of petroleum products has a great impact on the way it is transported in pipelines so as to avoid degradation and contamination. This work aims to presenting a global and preliminary approach about the transport of petroleum products in batches in pipelines and in multi-product terminal lines towards its automation. Emphasis is placed on the batch formation and batch cut procedures, as well as on the features associated with the installation and instrumentation required to perform this task. The main factors responsible for increasing the mixing volume in batch transfers and for threatening the integrity of the products are highlighted. Several effective measures are pointed out to minimize the mixing volume generation. Among other benefits, they can promote reduction in the cost of transportation and in the amount of degraded products, simplified operational procedures and a minimum need for stocks to cope with its logistic.

The considerable increasing in the world petroleum consumption as the exhaustion of onshore reserves in the last decades leads the companies to exploit petroleum in offshore reserves (both shallow and deep water). As in onshore operations, accidents may also occur in submarine exploration. Leaking from submarine pipelines arises from corrosion pit and from axial or radial breakage. In all these three situations, the leaking is divided in three steps: pipeline depressurization until the internal pressure becomes equal to the external one; advective migration in which the driven force is the difference in the physical properties of the fluids; oil spill movement in the sea surface. A great number of mathematical models are Also available for the first and third steps. For the second one and theoretically, the most important situation, there is a restricted number of works respected to the oil volume leaked. The present study presents a software that is capable to accurate simulate a leakage through the advective migration phenomena. The software was validated for situations for different holes radii located in the upper side of a horizontal pipeline. Model results presented very good agreement with experimental data. (author)

The aim of this work is to evaluate the reliability of non-destructive test (NDT) techniques for the inspection of pipeline welds employed in the petroleum industry. Radiography, manual and automatic ultrasonic techniques using pulse-echo and time of flight diffraction (TOFD) were employed. Three classes of defects were analyzed: lack of penetration (LP), lack of fusion (LF) and undercut (UC). The tests were carried out on specimen made from pipelines containing defects, which had been artificially inserted on laying the weld bead. The results showed the superiority of the automatic ultrasonic tests for defect detection compared with the manual ultrasonic and radiographic tests. Additionally, artificial neural networks (ANN) were used in the detection and automatic classification of the defects

Transport of Tank 241-SY-101 Waste Slurry: Effects of Dilution and Temperature on Critical Pipeline Velocity

1999-01-01

This report presents the methods and results of calculations performed to predict the critical velocity and pressure drop required for the two-inch pipeline transfer of solid/liquid waste slurry from underground waste storage Tank 241-SY-101 to Tank 241-SY- 102 at the Hanford Site. The effects of temperature and dilution on the critical velocity were included in the analysis. These analyses show that Tank 241-SY-101 slurry should be diluted with water prior to delivery to Tank 241-SY-102. A dilution ratio of 1:1 is desirable and would allow the waste to be delivered at a critical velocity of 1.5 ft/sec. The system will be operated at a flow velocity of 6 ft/sec or greater therefore, this velocity will be sufficient to maintain a stable slurry delivery through the pipeline. The effect of temperature on the critical velocity is not a limiting factor when the slurry is diluted 1:1 with water. Pressure drop at the critical velocity would be approximately two feet for a 125-ft pipeline (or 250-ft equivalent straight pipeline). At 6 ft/sec, the pressure drop would be 20 feet over a 250-ft equivalent straight pipeline

In order to effectively protect long-distance gas pipelines against mountain damage in the areas in which underground mining is done, expansion compensators must be built in at certain distances. The tests to determine the slippage resistance and the highest permissible distance of expanders Lsub(max) in a transmission line NW 600 having a plastic insulation are described in this work. In addition, a way of calculating the Lsub(max) value from the existing data for pipes of varying diameter and different insulating material is shown.

Piping systems for the district heating, for the supply of natural gas, drinking water and extinguishing water as well as the transport of rain water and waste water - these are the most important tasks which have been fulfilled by the pipelines as a part of the underground infrastructure. Now, the classical distribution of tasks seems to become unstable. Waste water is not only dirty water, but a heat energy source which can be used atractively sometimes.Natural gas supply lines are recognized as energy storages for renewable energy sources in order to being used in times of excess electricity.

Status and Growth of Underground Science at WIPP

Science.gov (United States)

Rempe, Norbert T.

2008-10-01

The science community is increasingly taking advantage of research opportunities in the government-owned Waste Isolation Pilot Plant (WIPP), 655m underground near Carlsbad, NM. Discoveries so far include viable bacteria, cellulose, and DNA in 250 million-year old salt, preserved in an ultra-low background-radiation setting. Supplementing the overburden's shielding against cosmic radiation, terrestrial background from the host formation is less than five percent that of average crustal rock. In the past, WIPP accommodated development and testing of neutral current detectors for the Sudbury Neutrino Observatory and dark matter research, and it currently hosts two experiments pursuing neutrino-less double-beta decay. That scientists can listen to whispers from the universe in proximity to megacuries of radioactive waste lends, of course, credibility to the argument that WIPP itself is very safe. Almost a century of regional petroleum and potash extraction history and more than three decades of WIPP studies have generated a comprehensive body of knowledge on geology, mining technology, rock mechanics, geochemistry, and other disciplines relevant to underground science. Existing infrastructure is being used and can be expanded to fit experimental needs. WIPP's exemplary safety and regulatory compliance culture, low excavating and operating cost, and the high probability of the repository operating at least another 40 years make its available underground space attractive for future research and development. Recent proposals include low-photon energy counting to study internal dose received decades ago, investigations into ultra-low radiation dose response in cell cultures and laboratory animals (e.g., hormesis vs. linear no-threshold) and detectors for dark matter, solar and supernova neutrinos, and proton decay. Additional proposals compatible with WIPP's primary mission are welcome.

The principle, experiment and conclusion on the grease stain measurement using fast neutron are reported. The experiment equipment consist of 241 Am-Be fast neutron source, ZnS detector and BH1224 multichannel spectrometer. Paraffin is used instead of real grease stain. Steel plates are used instead of pipeline. The results of the experiment indicate that there is a good linearship between the logarithm of the reciprocal of the neutron transmissivity and the paraffin thickness. The measuring accuracy of the paraffin thickness is 0.6 mm in this experiment. (authors)

The role of the national petroleum company in petroleum development market

Energy Technology Data Exchange (ETDEWEB)

Lee, B J [Korea Energy Economics Institute, Euiwang (Korea, Republic of)

1997-08-01

The present century started with the creation of national petroleum companies, and it ends with those national petroleum companies exerting various types of efforts to increase the efficiency of their management. Especially, the efforts of these national petroleum companies are ever intensifying to adapt to new trends in the world petroleum market such as intensified competition, ever-deepening price unstableness, separation of structure between upstream and downstream portions, rapid development of petroleum development technologies, change of political systems and the demise of national borders, ever-increasing consciousness of environmental preservation, etc. Korea cannot be exempt from management rationalization efforts of national petroleum companies. Especially, Korea established its own national petroleum company in order to actively deal with these as its supply system is very weak. Therefore, the national petroleum company should create as many successful petroleum development businesses by actively carrying out petroleum development businesses domestically and overseas in order to establish a stable supply system of petroleum and to support the petroleum development businesses of civilian enterprises more effectively. The national petroleum company must, first of all, replace the bureaucracy with entrepreneurship. Esp., in order to enhance the efficiency of management, short- term outcome should not be emphasized over long-term tenure of petroleum development businesses, and excessive interference of government on the national petroleum company should be excluded. The entrepreneurship of the national petroleum company should be pursued in Positive-sum way, and its public image should be actively promoted through this. 35 refs., 11 figs., 32 tabs.

Full text: Cossetted deep underground, sheltered from cosmic ray noise, has always been a favourite haunt of neutrino physicists. Already in the 1930s, significant limits were obtained by taking a geiger counter down in Holborn 'tube' station, one of the deepest in London's underground system. Since then, neutrino physicists have popped up in many unlikely places - gold mines, salt mines, and road tunnels deep under mountain chains. Two such locations - the 1MB (Irvine/ Michigan/Brookhaven) detector 600 metres below ground in an Ohio salt mine, and the Kamiokande apparatus 1000m underground 300 km west of Tokyo - picked up neutrinos on 23 February 1987 from the famous 1987A supernova. Purpose-built underground laboratories have made life easier, notably the Italian Gran Sasso Laboratory near Rome, 1.4 kilometres below the surface, and the Russian Baksan Neutrino Observatory under Mount Andyrchi in the Caucasus range. Gran Sasso houses ICARUS (April, page 15), Gallex, Borexino, Macro and the LVD Large Volume Detector, while Baksan is the home of the SAGE gallium-based solar neutrino experiment.

Drinking water supplies are at risk of contamination from a variety of physical, chemical, and biological sources. Ranked among these threats are hazardous material releases from leaking or improperly managed underground storage tanks located at municipal, commercial, and industrial facilities. To reduce human health and environmental risks associated with the subsurface storage of hazardous materials, government agencies have taken a variety of legislative and regulatory actions--which date back more than 25 years and include the establishment of rigorous equipment/technology/operational requirements and facility-by-facility inspection and enforcement programs. Given a history of more than 470,000 underground storage tank releases nationwide, the U.S. Environmental Protection Agency continues to report that 7,300 new leaks were found in federal fiscal year 2008, while nearly 103,000 old leaks remain to be cleaned up. In this article, we report on an alternate evidence-based intervention approach for reducing potential releases from the storage of petroleum products (gasoline, diesel, kerosene, heating/fuel oil, and waste oil) in underground tanks at commercial facilities located in Rhode Island. The objective of this study was to evaluate whether a new regulatory model can be used as a cost-effective alternative to traditional facility-by-facility inspection and enforcement programs for underground storage tanks. We conclude that the alternative model, using an emphasis on technical assistance tools, can produce measurable improvements in compliance performance, is a cost-effective adjunct to traditional facility-by-facility inspection and enforcement programs, and has the potential to allow regulatory agencies to decrease their frequency of inspections among low risk facilities without sacrificing compliance performance or increasing public health risks. © 2012 Society for Risk Analysis.

Surviving and thriving in the current and future Nigerian petroleum products market

International Nuclear Information System (INIS)

Ali, Y.G.

1998-01-01

Currently, the petroleum products market is totally regulated. The operations and pricing mechanism must be conducted under prevailing Government rules and regulations. Indeed, in Nigeria today, no industry is as regulated as the Oil Industry (downstream emphasised) - which constitute the totality of petroleum products market. This situation has arisen as a result of the seeming classification of the oil industry as being strategic. Due to the regulations of the market, it can no longer adapt to the changing economic trend of liberalization and interplay of market forces, even when under serious pressure to yield to the dynamics of free market enterprise. As a result of the resistance to change, the market becomes stressed and over-burdened by the shackles of regulation which leads to a breakdown of the system and the impact becomes noticeable almost immediately. Needless to emphasize that, for the petroleum products market to survive and thrive, a cursory look at what obtains currently would afford us the opportunity to access the strength and weaknesses of such system, with a view to ascertaining the survival strategy to be applied for sustainable growth. In addition, a serious examination of the roles being played by the key operators in the petroleum products market otherwise called down stream operators (refineries, pipelines and marketers) is imperative. Since it requires the co-operation of the operators to achieve synergy in the market, any bottleneck arising from any of the sub-sectors has the capacity to disrupt the system

The regulations issued by the United States Environmental Protection Agency in 1988 require, with several exceptions, that underground storage tank systems containing petroleum fuels and hazardous chemicals be routinely tested for releases. This paper summarizes the release detection regulations for tank systems containing chemicals and gives a preliminary assessment of the approaches to release detection currently being used. To make this assessment, detailed discussions were conducted with providers and manufacturers of leak detection equipment and testing services, owners or operators of different types of chemical storage tank systems, and state and local regulators. While these discussions were limited to a small percentage of each type of organization, certain observations are sufficiently distinctive and important that they are reported for further investigation and evaluation. To make it clearer why certain approaches are being used, this paper also summarizes the types of chemicals being stored, the effectiveness of several leak detection testing systems, and the number and characteristics of the tank systems being used to store these products

Associated petroleum gas in Russia: reasons for non-utilization

This report studies the factors hindering increased utilization of associated petroleum gas (APG) in Russia. The issue of flaring versus utilization is studied from a Technology Innovation System (TIS) perspective, seeing the non-utilization issue as a problem of technology diffusion. There are many technological options available for APG utilization, but a main blocking mechanism in the Russian case is the Gazprom monopoly on gas transportation via their pipelines. A commonly discussed solution is policy to ensure third party access, but this study finds that this solution holds little potential, as its ramifications are too extensive and unacceptable to the key actor Gazprom. More promising solutions may be found in small, emerging engineering companies. (Author)

Adaptation of microalgae to a gradient of continuous petroleum contamination

International Nuclear Information System (INIS)

Carrera-Martinez, Daniel; Mateos-Sanz, Aranzazu; Lopez-Rodas, Victoria; Costas, Eduardo

2011-01-01

In order to study adaptation of microalgae to petroleum contamination, we have examined an environmental stress gradient by crude oil contamination in the Arroyo Minero River (AMR), Argentina. Underground crude oil has constantly leaked out since 1915 as a consequence of test drilling for possible petroleum exploitation. Numerous microalgae species proliferated in AMR upstream of the crude oil spill. In contrast, only four microalgal species were detected in the crude oil spill area. Species richness increases again downstream. Microalgae biomass in the crude oil spill area is dominated by a mesophile species, Scenedesmus sp. Effects of oil samples from AMR spill on photosynthetic performance and growth were studied using laboratory cultures of two Scenedesmus sp. strains. One strain (Se-co) was isolated from the crude oil spill area. The other strain (Se-pr) was isolated from a pristine area without petroleum contamination. Crude oil has undetectable effects on Se-co strain. In contrast crude oil rapidly destroys Se-pr strain. However, Se-pr strain can adapt to low doses of petroleum (≤3% v/v total hydrocarbons/water) by means of physiological acclimatization. In contrast, only rare crude oil-resistant mutants are able to grow under high levels of crude oil (≥10% v/v total hydrocarbons/water). These crude oil-resistant mutants have arisen through rare spontaneous mutations that occur prior to crude oil exposure. Species richness in different areas of AMR is closely connected to the kind of mechanism (genetic adaptation vs. physiological acclimatization) that allows adaptation. Resistant-mutants are enough to assure the survival of microalgal species under catastrophic crude oil spill.

Crossing Active Faults on the Sakhalin II Onshore Pipeline Route: Analysis Methodology and Basic Design

International Nuclear Information System (INIS)

Vitali, Luigino; Mattiozzi, Pierpaolo

2008-01-01

Twin oil (20 and 24 inch) and gas (20 and 48 inch) pipeline systems stretching 800 km are being constructed to connect offshore hydrocarbon deposits from the Sakhalin II concession in the North to an LNG plant and oil export terminal in the South of Sakhalin island. The onshore pipeline route follows a regional fault zone and crosses individual active faults at 19 locations. Sakhalin Energy, Design and Construction companies took significant care to ensure the integrity of the pipelines, should large seismic induced ground movements occur during the Operational life of the facilities. Complex investigations including the identification of the active faults, their precise location, their particular displacement values and assessment of the fault kinematics were carried out to provide input data for unique design solutions. Lateral and reverse offset displacements of 5.5 and 4.5 m respectively were determined as the single-event values for the design level earthquake (DLE)--the 1000-year return period event. Within the constraints of a pipeline route largely fixed, the underground pipeline fault crossing design was developed to define the optimum routing which would minimize stresses and strain using linepipe materials which had been ordered prior to the completion of detailed design, and to specify requirements for pipe trenching shape, materials, drainage system, etc. This Paper describes the steps followed to formulate the concept of the special trenches and the analytical characteristics of the Model

Seismodynamics of extended underground structures and soils: Statement of the problem and self-similar solutions

Science.gov (United States)

Georgievskii, D. V.; Israilov, M. Sh.

2015-07-01

In the problems of common vibrations of extended underground structures (pipelines and tunnels) and soil, an approach of the one-dimensional deformation of the medium is developed; this approach is based on the assumption that the soil deformation in the direction of seismic wave propagation coinciding with the pipeline axis is prevailing. The analytic solutions are obtained in the cases where the wave velocity in the soil is respectively less or greater than the wave velocity in the pipeline. The parameters influencing the pipeline fracture are revealed and methods for increasing the seismic stability of such structures are given. The possibility of the pipeline fatigue fracture is pointed out. The statements and solutions of parabolic problems modeling the physical phenomena in soils in the case of discontinuous velocity on the boundaries at the initial time are given. The notion of generalized vorticity diffusion is introduced and the cases of self-similarity existence are classified. A detailed analysis is performed for the non-Newtonian polynomial fluid, the medium close in properties to the rigidly ideally plastic body, and the viscoplastic Shvedov—Bingham body. In the case of physically linear medium, new self-similar solutions are obtained which describe the process of unsteady axially symmetric shear in spherical coordinates. The first approximation to the asymptotic solution of the problem of the vortex sheet diffusion is constructed in a medium with small polynomial nonlinearity. The solutions polynomially decreasing to zero as the self-similar variable increases are proposed in the class of two-constant fluids.

Studies on the earthquake resistance design of underground site for such large important structures as nuclear power plants, high-level radioactive waste repositories, LNG tanks, petroleum tanks, big power transmission installations and compressed air energy storage installations have been examined at our research institute. The observations of earthquake have been examined at Shiroyama underground hydroelectric power station since July 1976 as one of the demonstration of the earthquake resistance, and the first report was already published. After the time accelerometers and dynamic strain meters were additionally installed. Good acceleration waves and dynamic strain waves of the Izu-Hanto-Toho-Oki Earthquake, June 29, 1980 were observed at Shiroyama site, at which the hypocentral distance is 77 km and the intensity scale is about 4. In this report, the characteristic of the oscillation wave in the neighborhood of underground cavity and the relationships among accelerations, velocities, deformations and dynamic strains are studied in detail on the above earthquake data.

A detailed historical review is given on the problem of underground coal gasification (UCG) with emphasis on its physical, chemical, technological and financial aspects. The experience of USA, Japan, former USSR, Belgium, UK and France is described. The feasibility of UCG in the Dobrudzhan Coal Bed in Bulgaria is discussed. The deposit has reserves of about 1.5 billion tones at relatively shallow depths. Almost the whole scale from long flame to dry coal is covered. According to its coalification degree the bed belongs to gas coal - V daf 35-40%; C daf 80-83%, eruption index = 1. Enriched samples has low sulfur content - 0.6-1.5% and low mineral content - 6-12%. Having in mind the lack of domestic natural gas and petroleum resources, the authors state that the utilisation of the bed will alleviate the energy problems in Bulgaria. 24 refs., 5 figs., 1 tab

Constructing natural gas pipelines in wide areas requires investments of a huge amount. Many countries are building natural gas supply infrastructures under public support as nations' basic policy of promoting use of natural gas. This paper describes the present conditions of building pipelines in Western Europe, the U.S.A., Korea and Taiwan. In Western Europe, transporting companies established in line with the national policy own trunk pipelines and storage facilities, and import and distribute natural gas. The U.S.A. has 2300 small and large pipeline companies bearing transportation business. Pipelines extend about 1.9 million kilometers in total, with trunk pipelines accounting for about 440,000 kilometers. The companies are given eminent domain for the right of way. Korea has a plan to build a pipeline network with a distance of 1600 kilometers in around 2000. Taiwan has completed trunk pipelines extending 330 kilometers in two years. In Japan, the industry is preparing draft plans for wide area pipeline construction. 5 figs., 1 tab.

State of Tabasco: A Mexican petroleum district. Ein mexikanischer Erdoelstaat: Tabasco

Energy Technology Data Exchange (ETDEWEB)

Jacobsen, M.

1986-01-01

The Tabasco region is located in the southeast of Mexico. Before the petroleum boom in the mid seventies, agriculture was its dominant source of revenue. Farmers were generally earning their living by the small- and medium-scale production of basic foods, the cultivation and export of tropical fruits (cyclical phases of banana and cocoa cultivation) as well as by cattle-breeding. The discovery and exploration of extensive petroleum deposits placed in the hands of the national oil company PEMEX resulted in drastic and complex changes of the country's socio-economic structures. The publication reveals the gloomy situation of the Tabasco region. Within a few years only the PEMEX activities have 'covered' Tabasco with an 'oil slick' which has not - as might be assumed - contributed to a general prosperity but to the destruction of the environment, the speculation on real estate, extensive corruption and, which is more, to an always increasing proletarization and pauperization of that part of the population which is not directly connected to the pipeline.

Activities of the Nova Scotia Registry of Mineral and Petroleum Titles are described, including statistical information about staking and mining activity in the province during 1999. In terms of activities, the Registry receives applications and issues licenses and leases for mineral and petroleum rights, receives statements of exploration expenditures and assessment reports that pertain to renewal of licenses and leases, maintains maps showing the disposition of lands under license or lease, and maintains a system of prospector registration. In addition, the Registry processes applications for underground gas storage rights and treasure trove rights and maintains a database of information concerning production and employment in Nova Scotia mines and quarries. At the end 1999 there were 230,660 hectares under exploration licence. Exploration expenditures, including engineering, economic and feasibility studies during 1999 totalled $4.2 million, mostly by junior mining companies searching for industrial mineral commodities. Mining activity during 1999 generated revenues of $340 million. Coal production dropped by 25 per cent, due mainly to the closure of the Phalen Mine. Gypsum production was up to 7.9 million tonnes; shipments of cement, barite and clay products also increased during 1999; salt production remained unchanged from 1998 with 842,000 tonnes. Production of construction aggregates totalled 10.6 million tonnes, down slightly from the year before. Mineral industry employment was roughly 2,500 persons, down by 24 per cent from 1998 levels, due primarily to the closure of the Phalen Mine.

The rationale developed by a United Nations team to estimate the fate and transport of spilled oil remaining on the ground in the Pechora River basin in Russia following the Komi Pipeline spill disaster, was presented. The team consisted of experts from Norway, Canada, the United States and the European Union. Detailed background of the spill event, petroleum industry setting, geographic setting and hydrology of the regions was presented. Nine contaminated sites were identified. A worst case scenario was developed for the fate of the spilled oil. It was estimated that 93 000 - 97 000 tonnes of oil remained on the ground. Further pollution of the environment outside of Russia was considered unlikely under the circumstances, but petroleum contamination of the drinking water, tar balls and residual oil were expected to continue to persist in the affected area for many months. The UN team concluded that chronic pollution posed a significant threat to the region's natural resources. 4 refs., 3 figs

Using Tracer Technology to Characterize Contaminated Pipelines

Maresca, Joseph, W., Jr., Ph.D.; Bratton, Wesley, L., Ph.D., P.E.; Dickerson, Wilhelmina; Hales, Rochelle

2005-12-30

The Pipeline Characterization Using Tracers (PCUT) technique uses conservative and partitioning, reactive or other interactive tracers to remotely determine the amount of contaminant within a run of piping or ductwork. The PCUT system was motivated by a method that has been successfully used to characterize subsurface soil contaminants and is similar in operation to that of a gas chromatography column. By injecting a ?slug? of both conservative and partitioning tracers at one end (or section) of the piping and measuring the time history of the concentration of the tracers at the other end (or another section) of the pipe, the presence, location, and amount of contaminant within the pipe or duct can be determined. The tracers are transported along the pipe or duct by a gas flow field, typically air or nitrogen, which has a velocity that is slow enough so that the partitioning tracer has time to interact with the contaminant before the tracer slug completely passes over the contaminate region. PCUT not only identifies the presence of contamination, it also can locate the contamination along the pipeline and quantify the amount of residual. PCUT can be used in support of deactivation and decommissioning (D&D) of piping and ducts that may have been contaminated with hazardous chemicals such as chlorinated solvents, petroleum products, radioactive materials, or heavy metals, such as mercury.

Pipeline transportation of emerging partially upgraded bitumen

Luhning, R.W.; Anand, A.; Blackmore, T.; Lawson, D.S.

2002-01-01

The recoverable reserves of Canada's vast oil deposits is estimated to be 335 billion barrels (bbl), most of which are in the Alberta oil sands. Canada was the largest import supplier of crude oil to the United States in 2001, followed by Saudi Arabia. By 2011, the production of oil sands is expected to increase to 50 per cent of Canada's oil, and conventional oil production will decline as more production will be provided by synthetic light oil and bitumen. This paper lists the announced oil sands projects. If all are to proceed, production would reach 3,445,000 bbl per day by 2011. The three main challenges regarding the transportation and marketing of this new production were described. The first is to expand the physical capacity of existing pipelines. The second is the supply of low viscosity diluent (such as natural gas condensate or synthetic diluent) to reduce the viscosity and density of the bitumen as it passes through the pipelines. The current pipeline specifications and procedures to transport partially upgraded products are presented. The final challenge is the projected refinery market constraint to process the bitumen and synthetic light oil into consumer fuel products. These challenges can be addressed by modifying refineries and increasing Canadian access in Petroleum Administration Defense District (PADD) II and IV. The technology for partial upgrading of bitumen to produce pipeline specification oil, reduce diluent requirements and add sales value, is currently under development. The number of existing refineries to potentially accept partially upgraded product is listed. The partially upgraded bitumen will be in demand for additional upgrading to end user products, and new opportunities will be presented as additional pipeline capacity is made available to transport crude to U.S. markets and overseas. The paper describes the following emerging partial upgrading methods: the OrCrude upgrading process, rapid thermal processing, CPJ process for

Full Text Available Sulfur oxide (SO2 and hydrogen sulfide (H2S are considered as one of the major air pollutants in the world today. In addition, high sulfur levels in petroleum distillates can promote the deactivation of catalysts through poisoning in fluidized catalytic cracking (FCC during hydrocracking of the heavy distillates to lighter ones. The presence of high sulfur-containing compounds in the process streams could cause corrosion of piping and fittings and equipment, thereby damaging the pipelines and leading to air emissions of sulfur-containing compounds, which are undesirable for mankind and his environment. In many cases, a large quantity of SOx is released into the atmosphere when petroleum distillates that contain substantial amount of sulphur-containing compounds are used as fuel and combust. In this article, a short overview of different desulfurization methods that are employed to remove sulfur from petroleum distillates is provided. In particular, the review concentrates on biodesulfurization technique. In addition, this article intends to provide its readers current status of biodesulfurization (BDS. It critically analyses the trend in the development of the technology to showcase its strength and weakness that could pave a way for future opportunities. Approaches that are suitable to remediate sulfur-contaminated environment are discussed as well. Lastly, speculations on future directions or opportunities that require exploration are provided as a way of provoking the thoughts of researchers in this field.

This report addresses the site characterization of two historical underground storage tank petroleum hydrocarbon release sites identified by Corrective Action Site (CAS) Numbers 02-02-03 and 09-02-01. The sites are located at the Nevada Test Site in Areas 2 and 9 and are concrete bunker complexes (Bunker 2-300, and 9-300). Characterization was completed using drilling equipment to delineate the extent of petroleum hydrocarbons at release site 2-300-1 (CAS 02-02-03). Based on site observations, the low hydrocarbon concentrations detected, and the delineation of the vertical and lateral extent of subsurface hydrocarbons, an ``A through K`` evaluation was completed to support a request for an Administrative Closure of the site.

The petroleum sector is highly significant for the Norwegian economy. Its share of gross domestic product, exports and total government revenues has been substantial over the past two decades, reaching a particularly high level in 2000 and 2001. The principal reason why revenues were so high in these two years is a combination of high oil prices, a strong USD against the NOK and historically high petroleum production. The share of petroleum investment in total capital spending in the Norwegian economy was at its highest in the early 1990s. Total investment in the petroleum sector has been above NOK 40 bn every year since 1992, and peaked in 1998 at roughly NOK 80 bn. Capital spending declined to around NOK 56.9 bn in 2001. The government's most important revenue sources in recent years have been cash flow from the state's direct financial interest (SDFI) and from taxes. Production of crude oil has averaged around three mill barrels per day since 1996. The figure for 2001 was 3.1 mill barrels. Including natural gas liquids (NGL) and condensate raises the 2001 average to 3.4 mill barrels oe per day. At 53 mill scm oe, gas production was also high in 2001. Oil production is expected to remain more or less unchanged over the next few years, and then to go into a gradual decline. Gas output, on the other hand, should expand substantially over the coming decade and is expected to be increasingly significant in Norwegian petroleum output in future. The petroleum sector is also a substantial player internationally. Norway ranks as the world's sixth largest producer and third largest net exporter of oil. It is also the world's third largest exporter of pipeline gas, and Norwegian foreign sales of this commodity accounted for about two per cent of global consumption in 2001. Roughly 10 per cent of west European gas consumption is covered from Norway. Several changes were made to state participation in the petroleum sector during 2001. The government sold

This paper describes the experience of PETROBRAS Transporte S.A. - TRANSPETRO concerning standardization of its industrial maintenance of oil pipelines and terminals. This standardization initiative has been carried out within the Oil Pipelines and Terminals Standardization Program (PRONOT), focusing on planning, preparation and implementation of standards and five corporate operational procedures referring to TRANSPETRO's industrial maintenance activities. The process promoted the integration of isolated regional initiatives, and consequently the sense of unity and creation of a nucleus consisting of 30 professionals who mobilized a learning network with great capillarity. In this context, the paper presents the results of implementing corporate standards, based on internationally recognized yardsticks such as American Petroleum Institute (API), US Department of Transportation (DOT) and American Society of Mechanical Engineers (ASME), as well as PETROBRAS standards. It covers the following topics: an overview of the whole process; preparation of corporate operational procedures, which resulted in a total of 5 standards against 60 in the original situation; preparation and implementation of visual quick guides corresponding to the new corporate operational procedures; and proposal of a set of industrial maintenance performance indicators in compliance with operational guidelines established by TRANSPETRO's Oil Pipelines and Terminals business segment.

Analysis pipelines are an essential part of bioinformatics research, and ad hoc pipelines are frequently created by researchers for prototyping and proof-of-concept purposes. However, most existing pipeline management system or workflow engines are too complex for rapid prototyping or learning the pipeline concept. A lightweight, user-friendly and flexible solution is thus desirable. In this study, we developed a new pipeline construction and maintenance tool, PipelineDog. This is a web-based integrated development environment with a modern web graphical user interface. It offers cross-platform compatibility, project management capabilities, code formatting and error checking functions and an online repository. It uses an easy-to-read/write script system that encourages code reuse. With the online repository, it also encourages sharing of pipelines, which enhances analysis reproducibility and accountability. For most users, PipelineDog requires no software installation. Overall, this web application provides a way to rapidly create and easily manage pipelines. PipelineDog web app is freely available at http://web.pipeline.dog. The command line version is available at http://www.npmjs.com/package/pipelinedog and online repository at http://repo.pipeline.dog. ysun@kean.edu or xing@biology.rutgers.edu or ysun@diagnoa.com.

This work concerns in the development of a study on mapping and detection of structures and geological and geotechnical features associated with karstic relief and its implications in terms of ground stability to support the pipeline as well as from the point of view of cavities / caves conservation, potentially impacted by this activity. The limited mobility of track, carried by the existing restrictions, make the route of the Cacimbas-Catu pipeline pass through the cities of Itapebi (BA), Belomonte (BA), Mascote (BA) e Camaca (BA), where the local geology is characterized by rocks of Rio Pardo Group, dating from the Superior proterozoic (lower sequence predominantly carbonatic and upper sequence predominantly terrigenous). The study included a survey of secondary data, a field survey confirming karstic features, a 2D and subsequently 3D tomography survey, and a drilling survey to direct research at points of geo-electrical anomalies. The work did not identify underground cavities on the Cacimbas-Catu pipeline route. Even taking the studies presented geo-electric anomalies the direct investigation did not confirm the presence of voids in sub-surface, which enables the implementation of pipelines in this place, however the presence of electric anomalies with high resistivity indicate geotechnical areas where special care should be taken in relation to the stability of the ground.

Today, the most modern directional drilling technology not only is used in case of very deep drillings (deeper or longer than 2,000 meter) by means of deep-level drilling rigs, but also with small, highly mobile universal drilling rigs. Thus, drilling costs are reduced, and unconventional hydrocarbons (methane gas - oil shale and shale gas) deposits are explores economically. Furthermore, known near-surface petroleum deposits in Northern Germany as well as in other parts of the Earth (such as in Romania, the U.S.A. or in Canada) which extraction of petroleum is very low already are interesting economically. Furthermore, today it is possible to investigate with controlled drillings more economically and with more safe sites for a possibly final storage of highly radioactive wastes. Controlled drillings may give an answer to geotechnical questions on highly inaccessible on optimum points for drilling wells in order to plan underground cavities or to investigate tunnel axes geotechnical or hydrological.

Hydrocarbons are nonrenewable resources but today they are the cheaper and easier energy we have access and will remain the main source of energy for this century. Nevertheless, their exploration is extremely high-risk, very expensive and time consuming. In this context, satellite technologies for Earth observation can play a fundamental role by making hydrocarbon exploration more efficient, economical and much more eco-friendly. Complementary to traditional geophysical methods such as gravity and magnetic (gravmag) surveys, satellite remote sensing can be used to detect onshore long-term biochemical and geochemical alterations on the environment produced by invisible small fluxes of light hydrocarbons migrating from the underground deposits to the surface, known as microseepage effect. This paper describes two case studies: one in South Sudan and another in Mozambique. Results show how remote sensing is a powerful technology for detecting active petroleum systems, thus supporting hydrocarbon exploration in remote or hardly accessible areas and without the need of any exploration license.

The degradation problem of petroleum products arises since hydrocarbon acts as an excellent food source for a wide variety of microorganisms. Microbial activity leads to unacceptable level of turbidity, corrosion of pipeline and souring of stored product. The present study emphasizes the role of Bacillus cereus ACE4 on degradation of diesel and its influence on corrosion of API 5LX steel. A demonstrating bacterial strain ACE4 was isolated from corrosion products and 16S rRNA gene sequence analysis showed that it has more than 99% similarity with B. cereus. The biodegradation and corrosion studies revealed that B. cereus degraded the aliphatic protons and aromatic protons in diesel and is capable of oxidizing ferrous/manganese into oxides. This is the first report that discloses the involvement of manganese oxidizer B. cereus ACE4 on biodegradation of diesel and its influence on corrosion in a tropical country pipeline

Bioventing feasibility study of low permeability soils for remediation of petroleum contamination

Brackney, K.M.

1994-01-01

A site characterization of leaking underground gasoline and diesel storage tanks at the University of Idaho, West Farm Operations Center, identified approximately 800 cubic yards of petroleum-contaminated soil exceedingly regulatory action limits of 100 ppm TPH. Bioventing, a combination of in situ soil vapor extraction and microbial degradation, was selected as a remedial alternative on the basis of the presumably unsaturated paleo-soil with a 45-foot depth to groundwater, and a microbial study which concluded that indigenous petroleum-degrading microorganisms existed throughout the contamination. Soil vapor extraction tests were conducted by applying a 60-inch water column vacuum to a soil vapor extraction well and monitoring pneumatic pressure drawdown in 12 adjacent pneumatic piezometers and vertically distributed piezometer clusters. Pressure drawdown vs time data plots indicated that air permeability is inadequate everywhere at the site except at 20 feet below ground surface. Low soil permeability creates conditions for a perched water table that was documented during the investigation, resulting in unsatisfactory conditions for in situ bioventing. 8 refs., 14 figs

2015-01-01

An increasing number of tower-type boilers have been selected for advanced double reheat power plants, due to the uniform flue gas profile and the smooth steam temperature increase. The tall height and long steam pipelines lengths will however, result in dramatic increases in the difficulty of construction, as well as increased power plant investment cost. Given these factors, a novel partially-underground tower-type boiler design has been proposed in this study, which has nearly half of the boiler embedded underground, thereby significantly reducing the boiler height and steam pipeline lengths. Thermodynamic and economic analyses were quantitatively conducted on a 1000 MW advanced double reheat steam cycle. Results showed that compared to the reference power plant, the power plant with the proposed tower-type boiler design could reduce the net heat rate by 18.3 kJ/kWh and could reduce the cost of electricity (COE) by $0.60/MWh. The study also investigated the effects of price fluctuations on the cost-effectiveness of the reference power plant, for both the conventional and the proposed tower-type boilers designs, and found that the double reheat power plant with the proposed tower-type boiler design would be even more competitive and price-effective when the coal price and the investment costs increase. The research of this paper may provide a promising tower-type boiler design for advanced double reheat power plants with lower construction complexity and better cost-effectiveness. - Highlights: • A partially-underground tower-type boiler in double reheat power plants is proposed. for double reheat power plants is proposed. • Thermodynamic and economic analyses are quantitatively conducted. • Better energetic efficiency and greater economic benefits are achieved. • The impacts of price fluctuations on the economic feasibility are discussed

Using biodiesel in place of petroleum diesel is considered by several underground metal and nonmetal mine operators to be a viable strategy for reducing the exposure of miners to diesel particulate matter. This study was conducted in an underground experimental mine to evaluate the effects of soy methyl ester biodiesel on the concentrations and size distributions of diesel aerosols and nitric oxides in mine air. The objective was to compare the effects of neat and blended biodiesel fuels with those of ultralow sulfur petroleum diesel. The evaluation was performed using a mechanically controlled, naturally aspirated diesel engine equipped with a muffler and a diesel oxidation catalyst. The effects of biodiesel fuels on size distributions and number and total aerosol mass concentrations were found to be strongly dependent on engine operating conditions. When fueled with biodiesel fuels, the engine contributed less to elemental carbon concentrations for all engine operating modes and exhaust configurations. The substantial increases in number concentrations and fraction of organic carbon (OC) in total carbon over the baseline were observed when the engine was fueled with biodiesel fuels and operated at light-load operating conditions. Size distributions for all test conditions were found to be single modal and strongly affected by engine operating conditions, fuel type, and exhaust configuration. The peak and total number concentrations as well as median diameter decreased with an increase in the fraction of biodiesel in the fuels, particularly for high-load operating conditions. The effects of the diesel oxidation catalyst, commonly deployed to counteract the potential increase in OC emissions due to use of biodiesel, were found to vary depending upon fuel formulation and engine operating conditions. The catalyst was relatively effective in reducing aerosol number and mass concentrations, particularly at light-load conditions, but also showed the potential for an

A Novel Method to Enhance Pipeline Trajectory Determination Using Pipeline Junctions.

Sahli, Hussein; El-Sheimy, Naser

2016-04-21

Pipeline inspection gauges (pigs) have been used for many years to perform various maintenance operations in oil and gas pipelines. Different pipeline parameters can be inspected during the pig journey. Although pigs use many sensors to detect the required pipeline parameters, matching these data with the corresponding pipeline location is considered a very important parameter. High-end, tactical-grade inertial measurement units (IMUs) are used in pigging applications to locate the detected problems of pipeline using other sensors, and to reconstruct the trajectories of the pig. These IMUs are accurate; however, their high cost and large sizes limit their use in small diameter pipelines (8″ or less). This paper describes a new methodology for the use of MEMS-based IMUs using an extended Kalman filter (EKF) and the pipeline junctions to increase the position parameters' accuracy and to reduce the total RMS errors even during the unavailability of above ground markers (AGMs). The results of this new proposed method using a micro-electro-mechanical systems (MEMS)-based IMU revealed that the position RMS errors were reduced by approximately 85% compared to the standard EKF solution. Therefore, this approach will enable the mapping of small diameter pipelines, which was not possible before.

Toxicology of oil field wastes. Hazards to livestock associated with the petroleum industry.

Science.gov (United States)

Edwards, W C

1989-07-01

In oil-producing states, the proximity of livestock to drilling operations and production sites often results in poisoning of animals from ingestion of crude oil, condensate, salt water, heavy metals, and caustic chemicals. The heavy metals encountered most frequently are lead from pipe joint compound and arsenicals and chromates used as corrosion inhibitors. Numerous toxic and caustic chemicals are used in drilling muds and fluids. Crude oil and salt water spills are common occurrences around production sites. Pipeline breaks may result in exposure of livestock to crude oil or refined petroleum hydrocarbons. Ingestion of petroleum hydrocarbons may result in sudden death from peracute bloat. The most common cause of illness or death following exposure to petroleum hydrocarbons is aspiration pneumonia, which may cause a chronic progressive deterioration of health, with death after several days or weeks. Cases in which livestock are exposed to oil, salt water, or caustic chemicals, but do not die acutely or from aspiration pneumonia are more frustrating to diagnose. In these cases, parasitism, poor nutrition, and other debilitating diseases must be considered. Anorexia, weight loss, and decreased rumen motility may be caused by a disruption of normal rumen function. Petroleum hydrocarbons, salt water, and caustic chemicals have the potential of altering rumen flora and enzymatic processes as well as damaging the ruminal and gastrointestinal epithelium. The toxicity of petroleum hydrocarbons appears to be related more closely to the volatility and viscosity of the product than to other factors. The more volatile straight chain and aromatic petroleum hydrocarbons have a greater potential for aspiration pneumonia and may produce an anesthetic-like action if absorbed systemically. The more volatile petroleum hydrocarbons also are more irritating to skin and mucous membranes and appear to be more damaging to rumen flora. Treatment of petroleum hydrocarbon ingestion is

Planning and scheduling for petroleum refineries using mathematical programming

2002-01-01

Full Text Available The objective of this paper is the development and solution of nonlinear and mixed-integer (MIP optimization models for real-world planning and scheduling problems in petroleum refineries. Firstly, we present a nonlinear planning model that represents a general refinery topology and allows implementation of nonlinear process models as well as blending relations. The optimization model is able to define new operating points, thus increasing the production of the more valuable products and simultaneously satisfying all specification constraints. The second part addresses scheduling problems in oil refineries, which are formulated as MIP optimization models and rely on both continuous and discrete time representations. Three practical applications closely related to the current refinery scenario are presented. The first one addresses the problem of crude oil inventory management of a refinery that receives several types of crude oil delivered exclusively by a single oil pipeline. Subsequently, two optimization models intended to define the optimal production policy, inventory control and distribution are proposed and solved for the fuel oil and asphalt plant. Finally, the planning model of Moro et al. (1998 is extended in order to sequence decisions at the scheduling level in the liquefied petroleum gas (LPG area for maximization of the production of petrochemical-grade propane and product delivery.

Statistical data provided by CONCAWE and US Department of Transportation confirms that the pipeline related spills are rare and mainly related to the old pipelines. Georgia's experience yet confirms the general sound guess that the situation in our countries is not the same as in western Europe or USA and accordingly the CONCAWE statistical data can not be applied mechanically. Two spills (although small and manageable), during the recent 4 years and some discovered illegal hot-taps on the Baku-Supsa pipeline indicate that the issue of third party intrusion risks is much higher in the region and well organized security system is required to protect the pipeline from intentional damage. Of course the pipeline system can not function isolated and it is integrated with the other systems of oil transportation, mainly with off-shore terminals and tankers. The most significant of the recorded pollution damages are related to the tanker collisions (like Prestige and Exxon Valdez cases). The basic fact, which we would like to stress, is that the environmental risks related to the tanker collisions are much higher for such confined or semi-confined systems as Black and Caspian seas. The overloading of the Black Sea transportation capacity and especially its limiting narrow point - the Bosporus will inevitably lead in future to the implementation of the restrictive measures limiting transportation of oil by tankers in the Black Sea. Therefore, the role of the BTC pipeline as major transportation system will increase significantly. We consider that responsibility of the scientific society is to facilitate this process as soon as the BTC pipeline is functional. The railway transportation of oil is quite

Pipelines 'R' us

The geopolitical background to the export of oil and gas from Kazakhstan by pipeline is explored with particular reference to the sensitivities of the USA. There are now a number of pipeline proposals which would enable Kazakhstan to get its hydrocarbons to world markets. The construction of two of these formed part of a major oil deal signed recently with China in the face of stiff competition from major US companies. The most convenient and cost effective route, connecting up with Iran's existing pipeline network to the Gulf, is unlikely to be developed given continuing US sanctions against Iran. Equally unlikely seems to be the Turkmenistan to Pakistan pipeline in the light of the political volatility of Afghanistan. US companies continue to face limits on export capacity via the existing Russian pipelines from Kazakhstan. A temporary solution could be to carry some oil in the existing pipeline from Azerbaijan to Georgia which has been upgraded and is due to become operational soon, and later in a second proposed pipeline on this route. The Caspian Pipeline Consortium, consisting of three countries and eleven international companies, is building a 1500 km pipeline from the Tergiz field to Novorossiysk on the Black Sea with a view to completion in 2000. An undersea pipeline crossing the Caspian from Azerbaijan is being promoted by Turkey. There is an international perception that within the next five years Kazakhstan could be in a position to export its oil via as many as half a dozen different routes. (UK)

The internal combustion engine; a simple solution for pollution from petroleum hydrocarbons

International Nuclear Information System (INIS)

Johnson, G.A.

1992-01-01

The internal combustion (IC) engine is an indirect cause of groundwater and soil contamination from petroleum hydrocarbons. Leaking underground storage tank systems that are used to store and distribute fuel for automobiles are a major cause of environmental degradation. That same IC engine which has indirectly caused the pollution is an excellent tool for cleaning up environmental contamination from petroleum releases. An extremely flexible clean-up system using an IC engine was designed, constructed and operated to recover free product, treat contaminated soil and remediate groundwater pollution. The treatment system uses the IC engine for vapor extraction, groundwater pumping, spray aeration and incineration. The IC engine is an excellent incinerator. The petroleum vapors are burned in the IC engine with a supplemental propane fuel. The engine drives a power-takeoff unit and provides energy for an air compressor, water pump, electrical generation and other accessories. Using waste to energy methods multiple techniques are being used in combination with different treatment technologies to optimize the remediation. As the remediation progresses the treatment system can be modified to use additional techniques. Another benefit that is directly associated with the IC engine is the presence of excess heat which is helpful in northern climates. The excess heat has many uses including spray aeration and enhanced biological remediation. The IC engine has several limitations and requires an understanding of the physical and chemical properties of the contamination. As with all environmental remediation, a proper understanding of the Hydrogeological System is critical. When properly applied the IC engine has many advantages over other methods of remediation for petroleum hydrocarbons

Highlights: • The influence of stochastic properties and conditions on permafrost foundation was investigated. • A stochastic analysis for the uncertain thermal characteristic of crude oil pipe is presented. • The mean temperature and standard deviation of foundation soils are obtained and analyzed. • Average standard deviation and maximum standard deviation of foundation soils increase with time. - Abstract: For foundation soils surrounding the crude oil pipeline in permafrost regions, the soil properties and the upper boundary conditions are stochastic because of complex geological processes and changeable atmospheric environment. The conventional finite element analysis of thermal characteristics for crude oil pipeline is always deterministic, rather than taking stochastic parameters and conditions into account. This study investigated the stochastic influence of an underground crude oil pipeline on the thermal stability of the permafrost foundation on the basis of a stochastic analysis model and the stochastic finite element method. A stochastic finite element program is compiled by Matrix Laboratory (MATLAB) software, and the random temperature fields of foundation soils surrounding a crude oil pipeline in a permafrost region are obtained and analyzed by Neumann stochastic finite element method (NSFEM). The results provide a new way to predict the thermal effects of the crude oil pipeline in permafrost regions, and it shows that the standard deviations in temperature increase with time when considering the stochastic effect of soil properties and boundary conditions, which imply that the results of conventional deterministic analysis may be far from the true value, even if in different seasons. It can improve our understanding of the random temperature field of foundation soils surrounding the crude oil pipeline and provide a theoretical basis for actual engineering design in permafrost regions.

Fluid in a pipeline or container at a refinery or at any of various petroleum producing operations is bombarded with neutrons and high energy gamma rays resulting from capture of thermal neutrons are detected. The spectra of the detected gamma rays are then analyzed to determine the concentration of the element chlorine, which gives an indication of the presence and concentration of salt water in the fluid. The concentration of sulfur and the percentage gas in the fluid may be determined simultaneously with the concentration of chlorine. (Auth.)

Stray current interaction in the system of two extensive underground conductors

International Nuclear Information System (INIS)

Machczynski, W.

1993-01-01

The important problem, technically, is to evaluate the harmful effects that an electrified railway has on nearby earth-return circuits (cables, pipelines). This paper considers the effects of a DC-electrified railway system on two extensive metal conductors buried in parallel in the vicinity of the tracks. The interaction between currents flowing in both underground conductors is taken into account, whereas the reaction of the conductors' currents on the track current is disregarded. The analysis given is applicable to any DC railway system in which tracks may be represented by a single earth return circuit with current energization. It is assumed in the paper that the system considered is linear and that the earth is homogeneous. The technical application of the method is illustrated by an example of computer simulation

Pipeline operators are continuously working to improve the safety of their systems and operations. In the US both liquid and gas pipeline operators have worked with the regulators over many years to develop more systematic approaches to pipeline integrity management. To successfully manage pipeline integrity, vast amounts of data from different sources needs to be collected, overlaid and analyzed in order to assess the current condition and predict future degradation. The efforts undertaken by the operators has had a significant impact on pipeline safety, nevertheless, during recent years we have seen a number of major high profile accidents. One can therefore ask how effective the pipeline integrity management systems and processes are. This paper will present one methodology 'The Pipeline System Operability Review' that can evaluate and rate the effectiveness of both the management systems and procedures, as well as the technical condition of the hardware. The result from the review can be used to compare the performance of different pipelines within one operating company, as well as benchmark with international best practices. (author)

Subsea oil well blowouts and pipeline leaks release oil and gas to the environment through vigorous jets. Predicting the breakup of the released fluids in oil droplets and gas bubbles is critical to predict the fate of petroleum compounds in the marine water column. To predict the gas bubble size in oil well blowouts and pipeline leaks, we observed and quantified the flow behavior and breakup process of gas for a wide range of orifice diameters and flow rates. Flow behavior at the orifice transitions from pulsing flow to continuous discharge as the jet crosses the sonic point. Breakup dynamics transition from laminar to turbulent at a critical value of the Weber number. Very strong pure gas jets and most gas/liquid co-flowing jets exhibit atomization breakup. Bubble sizes in the atomization regime scale with the jet-to-plume transition length scale and follow -3/5 power-law scaling for a mixture Weber number. Copyright © 2018 Elsevier Ltd.

Garcia, Claudio; Costa, Artur; Bittencourt, Euclides [TRANSPETRO - PETROBRAS Transporte, Rio de Janeiro, RJ (Brazil)

2005-07-01

Due to the growing relevance of safety and environmental protection policies in PETROBRAS and its subsidiaries, as well as official regulatory agencies and population requirements, integrity management of oil and gas pipelines became a priority activity in TRANSPETRO, involving several sectors of the company's Support Management Department. Inspection activities using intelligent PIGs, field correlations and replacement of pipeline segments are known as high cost operations and request complex logistics. Thus, it is imperative the adoption of management tools that optimize the available resources. This study presents Monte Carlo simulation method as an additional tool for evaluation and management of pipeline structural integrity. The method consists in foreseeing future physical conditions of most significant defects found in intelligent PIG In Line Inspections based on a probabilistic approach. Through Monte Carlo simulation, probability functions of failure for each defect are produced, helping managers to decide which repairs should be executed in order to reach the desired or accepted risk level. The case that illustrates this study refers to the reconditioning of ORSOL 14'' (35,56 mm) pipeline. This pipeline was constructed to transfer petroleum from Urucu's production fields to Solimoes port, in Coari, city in Brazilian Amazon Region. The result of this analysis indicated critical points for repair, in addition to the results obtained by the conventional evaluation (deterministic ASME B-31G method). Due to the difficulties to mobilize staff and execute necessary repairs in remote areas like Amazon forest, the probabilistic tool was extremely useful, improving pipeline integrity level and avoiding future additional costs.

In recent decades, due to the advancement and computational methods for solving optimization problems, the number of articles addressing the scheduling of products has grown. The mathematical models developed have proved useful to schedule from a single pipeline with multiple products to complex networks of multiple pipelines. Moreover, the planning of these activities is of even greater importance when considering the existence of new environmental requirements to be applied to production and marketing of petroleum products. An example of this paradigm shift is the reduction in fuel oil consumption due to increased share of natural gas in the Brazilian energy matrix. In this context, this paper proposes a mathematical model to obtain feasible solutions for problems of scheduling a network of pipelines considering replacing all or part of the demand for fuel oil to natural gas. We tested the model on three real instances of a multi commodity network consists of 4 terminals, 4 refineries and 8 unidirectional pipelines, considering a planning horizon of one week. (author)

Overview of slurry pipelines

Energy Technology Data Exchange (ETDEWEB)

Gandhi, R L

1982-01-01

Slurry pipelines have proven to be a technically feasible, environmentally attractive and economic method of transporting finely divided particles over long distances. A pipeline system normally consists of preparation, pipeline and utilization facilities and requires optimization of all three components taken together. A considerable amount of research work has been done to develop hydraulic design of a slurry pipeline. Equipment selection and estimation of corrosion-erosion are considered to be as important as the hydraulic design. Future applications are expected to be for the large-scale transport of coal and for the exploitation of remotely located mineral deposits such as iron ore and copper. Application of slurry pipelines for the exploitation of remotely located mineral deposits is illustrated by the Kudremukh iron concentrate slurry pipeline in India.

Photolysis of petroleum

International Nuclear Information System (INIS)

Bobra, M.

1992-05-01

A study was conducted to examine the chemical and physical changes that occur in oils as a result of photooxidation. A literature review of recent studies in petroleum photochemistry revealed reported effects of photo-induced reactions in petroleum, including changes in color, polymerization, solidification, increases in solubility and toxicity, and changes in interfacial properties. A list of products reported as a result of photolysis of petroleum is presented, including such compounds as aldehydes, ketones, esters, and lactones. The photoreactivity of various petroleum components is discussed and mechanisms of photooxidation of petroleum are suggested. In the experimental portion of the study, a variety of crude oils and petroleum products were used to determine how different oils are affected by photolysis, and to examine the importance of photolysis as a weathering process. Photooxidation products from several oils were isolated and identified, including aliphatic and aromatic acids, alcohols, and phenols. Some physical manifestations attributed to photolysis included yellowing, formation of precipitates or crusts, increases in density and viscosity with time, increases of asphaltene content in some oils, changes in pH of the surrounding water, and emulsification. 51 refs., 38 figs., 18 tabs

An integrated sensing technique for smart monitoring of water pipelines

Science.gov (United States)

Bernini, Romeo; Catapano, Ilaria; Soldovieri, Francesco; Crocco, Lorenzo

2014-05-01

Lowering the rate of water leakage from the network of underground pipes is one of the requirements that "smart" cities have to comply with. In fact, losses in the water supply infrastructure have a remarkable social, environmental and economic impact, which obviously conflicts with the expected efficiency and sustainability of a smart city. As a consequence, there is a huge interest in developing prevention policies based on state-of-art sensing techniques and possibly their integration, as well as in envisaging ad hoc technical solutions designed for the application at hand. As a contribution to this framework, in this communication we present an approach aimed to pursue a thorough non-invasive monitoring of water pipelines, with both high spatial and temporal resolution. This goal is necessary to guarantee that maintenance operations are performed timely, so to reduce the extent of the leakage and its possible side effects, and precisely, so to minimize the cost and the discomfort resulting from operating on the water supply network. The proposed approach integrates two sensing techniques that work at different spatial and temporal scales. The first one is meant to provide a continuous (in both space and time) monitoring of the pipeline and exploits a distributed optic fiber sensor based on the Brillouin scattering phenomenon. This technique provides the "low" spatial resolution information (at meter scale) needed to reveal the presence of a leak and call for interventions [1]. The second technique is based on the use of Ground Penetrating Radar (GPR) and is meant to provide detailed images of area where the damage has been detected. GPR systems equipped with suitable data processing strategies [2,3] are indeed capable of providing images of the shallow underground, where the pipes would be buried, characterized by a spatial resolution in the order of a few centimeters. This capability is crucial to address in the most proper way maintenance operations, by for

Todays, petroleum companies consider that despite the constant increase of petroleum consumption, petroleum will remain the main energy source for at least 40 years. However, after the Iraq conflict, new regional situations are changing. China, for instance, with its growing up demand, will change the physiognomy of the oil market. In parallel, from Indonesia to Africa, petroleum and religion interfere and explain the new conflict areas. As for the US strategy, which is not limited to the energy paradigm, it largely integrates energy in the main lines of its diplomacy, from the 'Wide Middle East' to the 'Sahel initiative', and in its position with respect to Venezuela

Jinguji, M; Imaizumi, H; Kunimatsu, S; Isei, T [National Institute for Resources and Environment, Tsukuba (Japan)

1997-05-27

With an objective to detect gas leaking from an underground gas pipeline, discussions have been given on a method which utilizes acoustic characteristics of leakage. On leaking sound generated from damaged portions, the form of damaging was hypothesized as pinholes, and spectra of leaking sounds from holes with different diameters were measured. The dominant frequency decreases as the hole diameter increases, while it is in a region of relatively high frequency of 1 kHz or higher. However, detection from the ground surface was impossible when cover soil has thickness from 0.5 to 1.5 m. In an experiment to measure leaking sound inside the pipe, pressure in the pipe was adjusted to 0.02 atm which is a standard pressure for a low-pressure pipe, and the sound was measured when the hole diameters were varied. In any of the results obtained by varying the hole diameter, spectra having the dominant frequency in the region of 1 kHz or higher were measured. In addition, it was found that sound pressure difference of as much as 50 dB at maximum is generated as compared with a case of no sound leakage. The above results verified that monitoring the high frequency of 1 kHz or higher is effective in detecting leakage from small damages. 2 refs., 4 figs.

Underground space planning in Helsinki

Directory of Open Access Journals (Sweden)

Ilkka Vähäaho

2014-10-01

Full Text Available This paper gives insight into the use of underground space in Helsinki, Finland. The city has an underground master plan (UMP for its whole municipal area, not only for certain parts of the city. Further, the decision-making history of the UMP is described step-by-step. Some examples of underground space use in other cities are also given. The focus of this paper is on the sustainability issues related to urban underground space use, including its contribution to an environmentally sustainable and aesthetically acceptable landscape, anticipated structural longevity and maintaining the opportunity for urban development by future generations. Underground planning enhances overall safety and economy efficiency. The need for underground space use in city areas has grown rapidly since the 21st century; at the same time, the necessity to control construction work has also increased. The UMP of Helsinki reserves designated space for public and private utilities in various underground areas of bedrock over the long term. The plan also provides the framework for managing and controlling the city's underground construction work and allows suitable locations to be allocated for underground facilities. Tampere, the third most populated city in Finland and the biggest inland city in the Nordic countries, is also a good example of a city that is taking steps to utilise underground resources. Oulu, the capital city of northern Finland, has also started to ‘go underground’. An example of the possibility to combine two cities by an 80-km subsea tunnel is also discussed. A new fixed link would generate huge potential for the capital areas of Finland and Estonia to become a real Helsinki-Tallinn twin city.

Underground openings production line 2012. Design, production and initial state of the underground openings

International Nuclear Information System (INIS)

2013-08-01

The Underground Openings Line Production Line report describes the design requirements, the design principles, the methods of construction and the target properties for the underground rooms required for the final repository. It is one of five Production Line reports, namely the: Underground Openings Line report, Canister report, Buffer report, Backfill report, Closure report. Together, these reports cover the lifespan of the underground phases of the final repository from the start of construction of the underground rooms to their closure. Posiva has developed reference methods for constructing the underground rooms. Tunnels will be constructed using the drill and blast technique, shafts will be constructed using raise boring and the deposition holes will be constructed by reverse down reaming. Underground openings will be made safe by reinforcement by using rock bolts, net or shotcrete, depending on which type of opening is being considered, and groundwater inflows will be limited by grouting. Posiva's requirements management system (VAHA) sets out the specifications for the enactment of the disposal concept at Olkiluoto under five Levels - 1 to 5, from the most generic to the most specific. In this report, the focus is on Level 4 and 5 requirements, which provide practical guidance for the construction of the underground openings. The design requirements are presented in Level 4 and the design specification in Level 5 In addition to the long-term safety-related requirements included in VAHA, there are additional requirements regarding the operation of underground openings, e.g. space requirements due to the equipment used and its maintenance, operational and fire safety. The current reference design for the disposal facility is presented based on the design requirements and design specifications. During the lifespan of the repository the reference design will be revised and updated according to the design principles as new information is available. Reference

A Mackenzie Valley Pipeline -- Getting the challenge into perspective

Energy Technology Data Exchange (ETDEWEB)

Cournoyea, N. J. [Iuvialuit Regional Corporation, Yellowknife, NT (Canada)

2000-07-01

Another perspective on a Mackenzie Valley pipeline is given by a former Premier and Minister of Energy, Mines and Petroleum Resources of the NWT. The author views a Mackenzie Valley Pipeline that would carry both American and Canadian natural gas down the Valley as the one that would offer Canada the largest return in terms of employment, income and fiscal benefits. It is her view that if the Alaska Highway pipeline were to be developed first, it would be much more difficult to link up Canadian gas later, and the loss of the estimated 70 Tcf of Canadian gas reserves would be catastrophic not only to resource owners, but to the public interest at large, since without this Canadian gas, other fuel sources would have to be used to meet the demand for energy, thereby increasing the production of carbon dioxide and added risk of accelerating global warming. This, of course, is in addition to the lost opportunity available to the Inuvialuit and other northern aboriginal people to set a course of economic development that would enable aboriginal people of the north to become full and equal participants in the northern and Canadian economies. It is an opportunity that can be realized only if all stakeholders meet the challenges and take their respective responsibilities seriously. This means action by the federal government to support and encourage the development of Canadian frontier gas, to put in place a fair and workable regulatory process, to help aboriginal people achieve a durable and fair share in the benefits of development, to ensure the protection of the environment and realize the goals of sustainable development. Industry and aboriginal leaders too, must show leadership by forging a genuine and effective partnership, and all stakeholders must cooperate to make Canadian frontier gas and pipeline development an example to the world of what sustainable development should and could be. Industry must also keep a perspective on the regulatory hurdles, on the

China has been one of the most important energy-political actors for quite some time now; the country is not only the world's biggest consumer and the third biggest producer of energy but also, since 1993, a net importer of petroleum. Using the example of petroleum supply, the author investigates the development of China's energy security strategy. He makes a distinction between internal and external energy policy. In the latter sector, the focus is on a policy process analysis of the construction of the Kazakhstan-China petroleum pipeline, which was started in 2009. As methods, he uses a path dependency and policy analysis approach. The author investigates the elements of the power supply strategy with regard to diversification of the various energy sources, the chances for autonomy of power supply, and the strategy for maritime and continental dependence on imported petroleum and natural gas. In this context, the importance of the energy resources of the Caspian region for China is investigated.

Decontamination device for pipeline

International Nuclear Information System (INIS)

Harashina, Heihachi.

1994-01-01

Pipelines to be decontaminated are parts of pipelines contaminated with radioactive materials, and they are connected to a fluid transfer means (for example, a bladeless pump) and a ball collector by way of a connector. The fluid of a mixture of chemical decontaminating liquid and spheres is sent into pipelines to be decontaminated. The spheres are, for example, heat resistant porous hard or soft rubber spheres. The fluid discharged from the pipelines to be decontaminated are circulated by way of bypassing means. The inner surface of the pipelines is decontaminated by the circulation of the fluid. When the bypass means is closed, the fluid discharged from the pipelines to be decontaminated is sent to the ball collector, and the spheres are captured by a hopper. Further, the liquid is sent to the filtrating means to filter the chemical contaminating liquid, and sludges contained in the liquid are captured. (I.N.)

Assessment of radiological status of underground tunnel of radiochemistry wing

Radiochemistry Wing, RLG has design based safety systems for lab exhaust and glove box ventilation exhaust. The respective exhaust headers are routed from the lab exhaust point to the filter house. The concretized underground tunnel runs between Radiochemistry wing, RLG and Filter house about 100 m away. It houses the main exhaust tunnel made of MS, has reportedly developed leakage in the MS lines of exhaust due to ageing. It was indicated by the inadequate ventilation to the lab exhaust which reduced ∼ 10 % of the total exhaust. It was decided to carry out the replacement of main exhaust duct subject to radiological safety and clearance from the regulatory agencies. Since the duct had been in use since past 40 years, HP assessment on contamination status, clearance from local safety committee and related regulatory agency are mandatory. In view of the same, the study on radiological parameters was taken up and the paper describes the results of our radiological surveillance. Proposed replacement work involves approximately estimated surface area of duct as 520 m 2 , volume of the material as 106 m 3 and the weight of material of exhaust duct as 12.5 tons. Underground tunnel of radiochemistry wing consists of 3 main segments. It was monitored thoroughly by radiation survey. Spot air sample was collected during the radiological survey. Around 200 swipes were taken from various portions of the segments and the effluent pipelines. Last two tunnel segment were not approachable. Smear swipes were taken from top, side, bottom and floor of each segment. Calibrated scintillation counters were used for assessment of μ air activity and μ contamination check. Spot air samples were taken during different operations showed no activity. Dose rate in the tunnel was found to be less than 1 μSv/h (0.1 mR/h). The μ contamination levels were found in increasing order from the first segment to the last segment. (0.05 - 0.1 Bq/cm 2 ). Effluent pipelines were found to have

It is impractical to transport bitumen and heavy oil by pipelines at ambient temperature unless diluents are added to reduce the viscosity. A diluted bitumen pipeline is commonly referred to as a dilbit pipeline. The diluent routinely used is natural gas condensate. Since natural gas condensate is limited in supply, it must be recovered and reused at high cost. This paper presented an alternative to the use of diluent to reduce the viscosity of heavy oil or bitumen. The following two basic design issues for a hot bitumen (hotbit) pipeline were presented: (1) modelling the restart problem, and, (2) establishing the maximum practical operating temperature. The transient behaviour during restart of a high temperature pipeline carrying viscous fluids was modelled using the concept of flow capacity. Although the design conditions were hypothetical, they could be encountered in the Athabasca oilsands. It was shown that environmental disturbances occur when the fluid is cooled during shut down because the ground temperature near the pipeline rises. This can change growing conditions, even near deeply buried insulated pipelines. Axial thermal loads also constrain the design and operation of a buried pipeline as higher operating temperatures are considered. As such, strain based design provides the opportunity to design for higher operating temperature than allowable stress based design methods. Expansion loops can partially relieve the thermal stress at a given temperature. As the design temperature increase, there is a point at which above grade pipelines become attractive options, although the materials and welding procedures must be suitable for low temperature service. 3 refs., 1 tab., 10 figs.

Petroleum and Health Care: Evaluating and Managing Health Care's Vulnerability to Petroleum Supply Shifts

Science.gov (United States)

Bednarz, Daniel; Bae, Jaeyong; Pierce, Jessica

2011-01-01

Petroleum is used widely in health care—primarily as a transport fuel and feedstock for pharmaceuticals, plastics, and medical supplies—and few substitutes for it are available. This dependence theoretically makes health care vulnerable to petroleum supply shifts, but this vulnerability has not been empirically assessed. We quantify key aspects of petroleum use in health care and explore historical associations between petroleum supply shocks and health care prices. These analyses confirm that petroleum products are intrinsic to modern health care and that petroleum supply shifts can affect health care prices. In anticipation of future supply contractions lasting longer than previous shifts and potentially disrupting health care delivery, we propose an adaptive management approach and outline its application to the example of emergency medical services.
