Production Trends of Shale Gas Wells  

E-Print Network (OSTI)

To obtain better well performance and improved production from shale gas reservoirs, it is important to understand the behavior of shale gas wells and to identify different flow regions in them over a period of time. It is also important to understand best fracture and stimulation practice to increase productivity of wells. These objectives require that accurate production analysis be performed. For accurate production analysis, it is important to analyze the production behavior of wells, and field production data should be interpreted in such a way that it will identify well parameters. This can be done by performing a detailed analysis on a number of wells over whole reservoirs. This study is an approach that will lead to identifying different flow regions in shale gas wells that include linear and bilinear flow. Important field parameters can be calculated from those observations to help improve future performance. The detailed plots of several wells in this study show some good numbers for linear and bilinear flow, and some unique observations were made. The purpose of this work is to also manage the large amount of data in such a way that they can be used with ease for future studies. A program was developed to automate the analysis and generation of different plots. The program can also be used to perform the simple calculations to calculate different parameters. The goal was to develop a friendly user interface that would facilitate reservoir analysis. Examples were shown for each flow period, i.e. linear and bilinear flow. Different plots were generated (e.g; Bob Plot (square root of time plot) and Fourth Root of Time Plot, that will help in measuring slopes and thus reservoir parameters such as fracture permeability and drainage area. Different unique cases were also observed that show a different behavior of well in one type of plot from another.

Foolproof completions for high rate production wells  

E-Print Network (OSTI)

Operators, especially those managing production from deepwater reservoirs, are striving to produce hydrocarbons at higher and higher rates without exposing the wells to completion failure risk. To avoid screen failures, recent studies have favored gravel pack (GP) and high rate water pack (HRWP) completions over high-permeability fracturing (HPF), known in the vernacular as a frac&pack (FP) for very high rate wells. While a properly designed GP completion may prevent sand production, it does not stop formation fines migration, and, over time, fines accumulation in the GP will lead to increasing completion skin. Although, and not always, the skin can be removed by acidizing, it is not practical to perform repeated acid treatments on deepwater wells, particularly those with subsea wellheads, and the alternative has been to subject the completion to increasingly high drawdown, accepting a high skin effect. A far better solution is to use a HPF completion. Of course the execution of a successful HPF is not a trivial exercise, and frequently, there is a steep learning curve for such a practice. This work explains the importance to HPF completions of the well trajectory through the interval to be hydraulically fractured, for production, not execution, reasons. A new model quantifies the effect of the well inclination on the connectivity between the fracture and the well via perforations. Guidelines based on the maximum target production rate, including forecasts of multiphase flow, are provided to size the HPF completion to avoid common completion failures that may result from high fluid rate and/or fines movement. Skin model will be developed for both vertical and deviated wells. Once the HPF is properly designed and executed, the operators should end up with a long term low skin good completion quality well. The well will be safely produced at the maximum flow rates, with no need for well surveillance and monitoring.

Production characteristics of some Cerro Prieto wells  

DOE Green Energy (OSTI)

An areal distribution of heat and mass production in the Cerro Prieto field has been presented for two different times to determine the initial state of the ..cap alpha.. and ..beta.. aquifers and the behavior of the field under production. It was found that, initially, the ..cap alpha.. and ..beta.. aquifers were hot and very hot respectively. Cold boundaries to the field were found to be located toward the west and northeast. Initially, fluid production from most wells was very high. M-53 and some wells southeast of Fault H produced very hot fluids at very high rates. Production from most wells declined over the years, possibly due to scaling in the wellbore, reduced recharge to the aquifer, high resistance to flow due to silica precipitation in the reservoir pores and/or relative permeability effects in the two-phase regions surrounding the wells. In most wells fluid enthalpies declined over the years, perhaps due to mixing with colder waters either drawn in from upper strata and/or from the cold lateral boundaries depending upon well location.

Underbalanced completions improve well safety and productivity  

Science Conference Proceedings (OSTI)

Recent advances in completion technology, especially the use of and advances in coiled tubing technology, have presented the petroleum industry with methods that were previously unknown or considered too risky. Specifically, coiled tubing drilling and underbalanced drilling have both proven to be effective and acceptable methods in industry today. Several methods have been presented that will allow for the well to be completed underbalanced. By utilizing these methods, the completion process can be carried out while experiencing the same benefits offered by underbalanced drilling. the well can be completed with minimal fluid loss, which will result in reduced formation damage and improved well productivity. This new approach to the completion process provides additional opportunities both for completing new wells and for reentering existing wells.

Increasing Well Productivity in Gas Condensate Wells in Qatar's North Field  

E-Print Network (OSTI)

Condensate blockage negatively impacts large natural gas condensate reservoirs all over the world; examples include Arun Field in Indonesia, Karachaganak Field in Kazakhstan, Cupiagua Field in Colombia,Shtokmanovskoye Field in Russian Barents Sea, and North Field in Qatar. The main focus of this thesis is to evaluate condensate blockage problems in the North Field, Qatar, and then propose solutions to increase well productivity in these gas condensate wells. The first step of the study involved gathering North Field reservoir data from previously published papers. A commercial simulator was then used to carry out numerical reservoir simulation of fluid flow in the North Field. Once an accurate model was obtained, the following three solutions to increasing productivity in the North Field are presented; namely wettability alteration, horizontal wells, and reduced Non Darcy flow. Results of this study show that wettability alteration can increase well productivity in the North Field by adding significant value to a single well. Horizontal wells can successfully increase well productivity in the North Field because they have a smaller pressure drawdown (compared to vertical wells). Horizontal wells delay condensate formation, and increase the well productivity index by reducing condensate blockage in the near wellbore region. Non Darcy flow effects were found to be negligible in multilateral wells due to a decrease in fluid velocity. Therefore, drilling multilateral wells decreases gas velocity around the wellbore, decreases Non Darcy flow effects to a negligible level, and increases well productivity in the North Field.

The Effect of Well Trajectory on Production Performance of Tight Gas Wells  

E-Print Network (OSTI)

Horizontal wells are a very important element in oil and gas industry due to their distinguished advantages. Horizontal wells are not technically horizontal. This is because of the structural nature of reservoir formations and drilling procedures. In response to the reservoir rock’s strength, the horizontal well deviates upward and downward while being drilled forming an undulating path instead of a horizontal. In this study, horizontal wells with an undulating trajectory within a gas reservoir have been studied. The aim of this research is to investigate the effect of the trajectory angle on pressure drop in horizontal wells. In addition, the contribution of water flow to pressure drop is a part of this research. Generally, water comes from different sources like an aquifer or a water flood job. In low permeability horizontal wells, hydraulic fracturing introduces water to gas wells. Water distribution is an important issue in gas wells production. In order to achieve the goal of this study, a model has been developed to simulate different situations for a horizontal well with an undulating trajectory in gas reservoirs. This study is a step forward to understand well performance in low permeability gas reservoirs.

Completion report: Raft River Geothermal Production Well Four (RRGP-4)  

DOE Green Energy (OSTI)

The fourth Raft River well was originally drilled to 866 m (2840 ft), for use as a test injection well. This well allowed the injection of geothermal fluids into the intermediate zone--above the geothermal production zone and below the shallow groundwater aquifers. After this testing, the well was deepened and cased for use as a production well. The well's designation was changed from RRGI-4 to RRGP-4. This report describes the drilling and completion of both drilling projects. Results of well tests are also included.

Failure of the casing of the Brady No. 5 resulted from severe external corrosion. The well is located in a mineral flat and it is proposed that during wet periods the exterior of the casing was exposed to aerated saturated chloride and/or sulfate salt solutions. These solutions appear to have completely destroyed the surface conductor and upper string casing and associated cements. The production casing then corroded until mechanical failure occurred.

Hanford wells  

SciTech Connect

The Site Characterization and Assessment Section of the Geosciences Department at Pacific Northwest Laboratory (PNL) has compiled a list of wells located on or near the Hanford Site. Information has been updated on wells existing from the days before construction of the Hanford Works to the present. This work was funded by the US Department of Energy (DOE). The list of wells will be used by DOE contractors who need condensed, tabular information on well location, construction, and completion dates. This report does not include data on lithologic logs and ground-water contamination. Moreover, the completeness of this list is limited because of new well construction and existing well modifications, which are continually under way. Despite these limitations, this list represents the most complete description possible of data pertaining to wells on or adjacent to the Hanford Site. 7 refs., 1 fig., 2 tabs.

Well Productivity in Gas-Condensate and Volatile Oil Reservoirs:  

E-Print Network (OSTI)

Wells in gas condensate reservoirs usually exhibit complex behaviours due to condensate deposit as the bottomhole pressure drops below the dew point. The formation of this liquid saturation can lead to a severe loss of well productivity and therefore lower gas recovery. A similar behaviour is observed in volatile oil reservoirs below the bubble point. Understanding these behaviours and extracting values of controlling parameters is necessary to evaluate well potential and design effective programmes to improve productivity. The Centre of Petroleum Studies at Imperial College London has been involved in research in these areas since 1997, sponsored mainly by consortia of oil companies. Results from this work have already greatly improved the understanding of well behaviour in gas condensate and volatile oil reservoirs and the ability to interpret well tests in such reservoirs. Work to-date has focused on vertical and horizontal wells in sandstone reservoirs. Much work remains to understand the behaviours of fractured wells and wells in naturally fractured reservoirs. The objective of this proposal is to complete the work performed to-date in sandstone reservoirs and to extend it to new well and reservoir characteristics, in order to develop a better understanding of near-wellbore effects in gas condensate and volatile oil reservoirs from well testing, and to use this understanding to develop new methods for predicting and improving well productivity in such reservoirs. The work will be performed by staff, MSc and PhD students from the Centre for Petroleum Studies at Imperial College, with input and guidance from industry partners.

Transient and Pseudosteady-State Productivity of Hydraulically Fractured Well  

E-Print Network (OSTI)

Numerical simulation method is used in this work to solve the problem of transient and pseudosteady-state flow of fluid in a rectangular reservoir with impermeable boundaries. Development and validation of the numerical solution for various well-fracture configurations are the main objectives of this research. The specific case of horizontal well intersected by multiple transverse fractures is the focus of the investigation. The solutions for different operating conditions, constant rate and constant pressure, are represented in the form of transient – peudosteady-state productivity indices. The numerical simulator is validated by comparing results to known analytical solution for radial flow, existing models of productivity for vertical well intersected by vertical fracture, and also with published tables of shape factors. Numerical simulation is a powerful tool to predict well performance. The complexities of well-fracture configurations can be modeled in a truly 3-dimensional system and the pressure and productivity responses for all of the flow regimes can be computed efficiently, enabling optimization of the well-fracture system.

Cementing temperatures for deep-well production liners  

SciTech Connect

Temperature of cement is an important factor in properly cementing deep well production liners, yet current methods of determining cement temperatures do not account for all variables. In this paper a computer model predicts temperatures of cement while pumping and while waiting on cement, compares computed and measured temperatures, defines the importance of certain cementing variables on temperatures, and provides an explanation of difficulties encountered while cementing liner tops.

Cerro Prieto cold water injection: effects on nearby production wells  

DOE Green Energy (OSTI)

The liquid-dominated Cerro Prieto geothermal field of northern Baja California, Mexico has been under commercial exploitation since 1973. During the early years of operation, all waste brines were sent to an evaporation pond built west of the production area. In 1989, cooled pond brines began to be successfully injected into the reservoir along the western boundary of the geothermal system. The injection rate varied over the years, and is at present about 20% of the total fluid extracted. As expected under the continental desert conditions prevailing in the area, the temperature and salinity of the pond brines change with the seasons, being higher during the summer and lower during the winter. The chemistry of pond brines is also affected by precipitation of silica, oxidation of H{sub 2}S and reaction with airborne clays. Several production wells in the western part of the field (CP-I area) showed beneficial effects from injection. The chemical (chloride, isotopic) and physical (enthalpy, flow rate) changes observed in producers close to the injectors are reviewed. Some wells showed steam flow increases, in others steam flow decline rates flattened. Because of their higher density, injected brines migrated downward in the reservoir and showed up in deep wells.

Performance Analysis & Optimization of Well Production in Unconventional Resource Plays  

E-Print Network (OSTI)

The Unconventional Resource Plays consisting of the lowest tier of resources (large volumes and most difficult to develop) have been the main focus of US domestic activity during recent times. Horizontal well drilling and hydraulic fracturing completion technology have been primarily responsible for this paradigm shift. The concept of drainage volume is being examined using pressure diffusion along streamlines. We use diffusive time of flight to optimize the number of hydraulic fracture stages in horizontal well application for Tight Gas reservoirs. Numerous field case histories are available in literature for optimizing number of hydraulic fracture stages, although the conclusions are case specific. In contrast, a general method is being presented that can be used to augment field experiments necessary to optimize the number of hydraulic fracture stages. The optimization results for the tight gas example are in line with the results from economic analysis. The fluid flow simulation for Naturally Fractured Reservoirs (NFR) is performed by Dual-Permeability or Dual-Porosity formulations. Microseismic data from Barnett Shale well is used to characterize the hydraulic fracture geometry. Sensitivity analysis, uncertainty assessment, manual & computer assisted history matching are integrated to develop a comprehensive workflow for building reliable reservoir simulation models. We demonstrate that incorporating proper physics of flow is the first step in building reliable reservoir simulation models. Lack of proper physics often leads to unreasonable reservoir parameter estimates. The workflow demonstrates reduced non-uniqueness for the inverse history matching problem. The behavior of near-critical fluids in Liquid Rich Shale plays defies the production behavior observed in conventional reservoir systems. In conventional reservoirs an increased gas-oil ratio is observed as flowing bottom-hole pressure is less than the saturation pressure. The production behavior is examined by building a compositional simulation model on an Eagle Ford well. Extremely high pressure drop along the multiple transverse hydraulic fractures and high critical gas saturation are responsible for this production behavior. Integrating pore-scale flow modeling (such as Lattice Boltzmann) to the field-scale reservoir simulation may enable quantifying the effects of high capillary pressure and phase behavior alteration due to confinement in the nano-pore system.

Altering Reservoir Wettability to Improve Production from Single Wells  

Science Conference Proceedings (OSTI)

Many carbonate reservoirs are naturally fractured and typically produce less than 10% original oil in place during primary recovery. Spontaneous imbibition has proven an important mechanism for oil recovery from fractured reservoirs, which are usually weak waterflood candidates. In some situations, chemical stimulation can promote imbibition of water to alter the reservoir wettability toward water-wetness such that oil is produced at an economic rate from the rock matrix into fractures. In this project, cores and fluids from five reservoirs were used in laboratory tests: the San Andres formation (Fuhrman Masho and Eagle Creek fields) in the Permian Basin of Texas and New Mexico; and the Interlake, Stony Mountain, and Red River formations from the Cedar Creek Anticline in Montana and South Dakota. Solutions of nonionic, anionic, and amphoteric surfactants with formation water were used to promote waterwetness. Some Fuhrman Masho cores soaked in surfactant solution had improved oil recovery up to 38%. Most Eagle Creek cores did not respond to any of the tested surfactants. Some Cedar Creek anticline cores had good response to two anionic surfactants (CD 128 and A246L). The results indicate that cores with higher permeability responded better to the surfactants. The increased recovery is mainly ascribed to increased water-wetness. It is suspected that rock mineralogy is also an important factor. The laboratory work generated three field tests of the surfactant soak process in the West Fuhrman Masho San Andres Unit. The flawlessly designed tests included mechanical well clean out, installation of new pumps, and daily well tests before and after the treatments. Treatments were designed using artificial intelligence (AI) correlations developed from 23 previous surfactant soak treatments. The treatments were conducted during the last quarter of 2006. One of the wells produced a marginal volume of incremental oil through October. It is interesting to note that the field tests were conducted in an area of the field that has not met production expectations. The dataset on the 23 Phosphoria well surfactant soaks was updated. An analysis of the oil decline curves indicted that 4.5 lb of chemical produced a barrel of incremental oil. The AI analysis supports the adage 'good wells are the best candidates.' The generally better performance of surfactant in the high permeability core laboratory tests supports this observation. AI correlations were developed to predict the response to water-frac stimulations in a tight San Andres reservoir. The correlations maybe useful in the design of Cedar Creek Anticline surfactant soak treatments planned for next year. Nuclear Magnetic Resonance scans of dolomite cores to measure porosity and saturation during the high temperature laboratory work were acquired. The scans could not be correlated with physical measurement using either conventional or AI methods.

Fully Coupled Well Models for Fluid Injection and Production  

SciTech Connect

Wells are the primary engineered component of geologic sequestration systems with deep subsurface reservoirs. Wells provide a conduit for injecting greenhouse gases and producing reservoirs fluids, such as brines, natural gas, and crude oil, depending on the target reservoir. Well trajectories, well pressures, and fluid flow rates are parameters over which well engineers and operators have control during the geologic sequestration process. Current drilling practices provided well engineers flexibility in designing well trajectories and controlling screened intervals. Injection pressures and fluids can be used to purposely fracture the reservoir formation or to purposely prevent fracturing. Numerical simulation of geologic sequestration processes involves the solution of multifluid transport equations within heterogeneous geologic media. These equations that mathematically describe the flow of fluid through the reservoir formation are nonlinear in form, requiring linearization techniques to resolve. In actual geologic settings fluid exchange between a well and reservoir is a function of local pressure gradients, fluid saturations, and formation characteristics. In numerical simulators fluid exchange between a well and reservoir can be specified using a spectrum of approaches that vary from totally ignoring the reservoir conditions to fully considering reservoir conditions and well processes. Well models are a numerical simulation approach that account for local conditions and gradients in the exchange of fluids between the well and reservoir. As with the mathematical equations that describe fluid flow in the reservoir, variation in fluid properties with temperature and pressure yield nonlinearities in the mathematical equations that describe fluid flow within the well. To numerically simulate the fluid exchange between a well and reservoir the two systems of nonlinear multifluid flow equations must be resolved. The spectrum of numerical approaches for resolving these equations varies from zero coupling to full coupling. In this paper we describe a fully coupled solution approach for well model that allows for a flexible well trajectory and screened interval within a structured hexahedral computational grid. In this scheme the nonlinear well equations have been fully integrated into the Jacobian matrix for the reservoir conservation equations, minimizing the matrix bandwidth.

Geothermal Well Stimulation  

DOE Green Energy (OSTI)

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

T-F and S/DOE Gladys McCall No. 1 well, Cameron Parish, Louisiana. Geopressured-geothermal well report, Volume II. Well workover and production testing, February 1982-October 1985. Final report. Part 1  

DOE Green Energy (OSTI)

The T-F and S/DOE Gladys McCall No. 1 well was the fourth in a series of wells in the DOE Design Wells Program that were drilled into deep, large geopressured-geothermal brine aquifers in order to provide basic data with which to determine the technological and economic viability of producing energy from these unconventional resources. This brine production well was spudded on May 27, 1981 and drilling operations were completed on November 2, 1981 after using 160 days of rig time. The well was drilled to a total depth of 16,510 feet. The target sands lie at a depth of 14,412 to 15,860 feet in the Fleming Formation of the lower Miocene. This report covers well production testing operations and necessary well workover operations during the February 1982 to October 1985 period. The primary goals of the well testing program were: (1) to determine reservoir size, shape, volume, drive mechanisms, and other reservoir parameters, (2) to determine and demonstrate the technological and economic viability of producing energy from a geopressured-geothermal brine aquifer through long-term production testing, and (3) to determine problem areas associated with such long-term production, and to develop solutions therefor.

Subterrene rock-melting concept applied to the production of deep geothermal wells  

DOE Green Energy (OSTI)

The drilling of wells comprises a large fraction of the costs of geothermal energy-extraction plants, and billions of dollars for wells will be needed before geothermal energy is nationally significant. Technical and cost studies were made of the application of the Subterrene concept, i.e., excavating and penetrating rocks or soils by melting, to deep wells such as may be used for dry-hot-rock or geopressure geothermal energy extraction systems. Technically, it was found that Subterrene requirements are compatible with those of current rotary drilling practices. Certain features of the rock-melting concept such as the glass lining on the borehole wall, and nonrotation, provide opportunities for the development of better well production techniques in hot wells. A typical optimum-cost well would be rotary-drilled in the upper regions and then rock-melted to total depth. Indicated cost-savings are significant: a 33 percent or 4.5 million dollars reduction from rotary drilled well costs are estimated for a 10 km depth well with bottom hole temperatures of 673 K. Even for normal geothermal gradient conditions, the savings for the 10 km depth is estimated as 23 percent or 2 million dollars.

Shale gas has become increasingly important to United States energy supply. During recent decades, the mechanisms of shale gas storage and transport were gradually recognized. Gas desorption was also realized and quantitatively described. Models and approaches special for estimating rate decline and recovery of shale gas wells were developed. As the strategy of the horizontal well with multiple transverse fractures (MTFHW) was discovered and its significance to economic shale gas production was understood, rate decline and pressure transient analysis models for this type of well were developed to reveal the well behavior. In this thesis, we considered a “Triple-porosity/Dual-permeability” model and performed sensitivity studies to understand long term pressure drawdown behavior of MTFHWs. A key observation from this study is that the early linear flow regime before interfracture interference gives a relationship between summed fracture half-length and permeability, from which we can estimate either when the other is known. We studied the impact of gas desorption on the time when the pressure perturbation caused by production from adjacent transference fractures (fracture interference time) and programmed an empirical method to calculate a time shift that can be used to qualify the gas desorption impact on long term production behavior. We focused on the field case Well A in New Albany Shale. We estimated the EUR for 33 wells, including Well A, using an existing analysis approach. We applied a unified BU-RNP method to process the one-year production/pressure transient data and performed PTA to the resulting virtual constant-rate pressure drawdown. Production analysis was performed meanwhile. Diagnosis plots for PTA and RNP analysis revealed that only the early linear flow regime was visible in the data, and permeability was estimated both from a model match and from the relationship between fracture halflength and permeability. Considering gas desorption, the fracture interference will occur only after several centuries. Based on this result, we recommend a well design strategy to increase the gas recovery factor by decreasing the facture spacing. The higher EUR of Well A compared to the vertical wells encourages drilling more MTFHWs in New Albany Shale.

Geothermal Well Technology Program  

DOE Green Energy (OSTI)

The high cost of drilling and completing geothermal wells is an impediment to the development of geothermal energy resources. Technological deficiencies in rotary drilling techniques are evidenced when drilling geothermal wells. The Division of Geothermal Energy (DGE) of the U.S. Department of Energy has initiated a program aimed at developing new drilling and completion techniques for geothermal wells. The goals of this program are to reduce well costs by 25% by 1982 and by 50% by 1986. An overview of the program is presented. Program justification which relates well cost to busbar energy cost and to DGE power-on-line goals is presented. Technological deficiencies encountered when current rotary drilling techniques are used for geothermal wells are discussed. A program for correcting these deficiencies is described.

Productivity and injectivity of horizontal wells. Quarterly report, April 1, 1994--June 30, 1994  

Science Conference Proceedings (OSTI)

In the fifth quarter of this project, progress was made concerning four of the stated objectives of the project. First, extensive sensitivity studies, based on reservoir simulation, have been performed on a field example to assess the effects of wellbore friction, inflow, skin, length, and diameter of the well, etc. on the productivity of a horizontal well. Secondly, the authors have launched a new phase of the project on developing models for scale-up and coarse grid pseudo functions for horizontal wells in heterogeneous reservoirs. The available methods have been applied to an example problem and their performance and limitations have been analyzed. Thirdly, the authors are in the process of developing a new analytical solution for the coning and cresting critical rates for horizontal wells. Finally, experimental data bases will be used to test the authors` newly developed general mechanistic model for two-phase flow.

A study of production/injection data from slim holes and production wells at the Oguni Geothermal Field, Japan  

DOE Green Energy (OSTI)

Production and injection data from slim holes and large-diameter wells at the Oguni Geothermal Field, Japan, were examined in an effort to establish relationships (1) between productivity of large-diameter wells and slim holes, (2) between injectivity and productivity indices and (3) between productivity index and borehole diameter. The production data from Oguni boreholes imply that the mass production from large-diameter wells may be estimated based on data from slim holes. Test data from both large- and small-diameter boreholes indicate that to first order the productivity and the injectivity indices are equal. Somewhat surprisingly, the productivity index was found to be a strong function of borehole diameter; the cause for this phenomenon is not understood at this time.

While fluid properties have been examined well into the 450/sup 0/F range, proppants have not been previously tested at elevated temperatures except in a few instances. The latest test data at geothermal temperatures is presented and some possible proppants and fluid systems that can be used are shown. Also discussed are alternative stimulation techniques for geothermal wells.

SELECTION AND TREATMENT OF STRIPPER GAS WELLS FOR PRODUCTION ENHANCEMENT, MOCANE-LAVERNE FIELD, OKLAHOMA  

Science Conference Proceedings (OSTI)

In 1996, Advanced Resources International (ARI) began performing R&D targeted at enhancing production and reserves from natural gas fields. The impetus for the effort was a series of field R&D projects in the early-to-mid 1990's, in eastern coalbed methane and gas shales plays, where well remediation and production enhancement had been successfully demonstrated. As a first step in the R&D effort, an assessment was made of the potential for restimulation to provide meaningful reserve additions to the U.S. gas resource base, and what technologies were needed to do so. That work concluded that: (1) A significant resource base did exist via restimulation (multiples of Tcf). (2) The greatest opportunities existed in non-conventional plays where completion practices were (relatively) complex and technology advancement was rapid. (3) Accurate candidate selection is the greatest single factor that contributes to a successful restimulation program. With these findings, a field-oriented program targeted at tight sand formations was initiated to develop and demonstrate successful candidate recognition technology. In that program, which concluded in 2001, nine wells were restimulated in the Green River, Piceance and East Texas basins, which in total added 2.9 Bcf of reserves at an average cost of $0.26/Mcf. In addition, it was found that in complex and heterogeneous reservoirs (such as tight sand formations), candidate selection procedures should involve a combination of fundamental engineering and advanced pattern recognition approaches, and that simple statistical methods for identifying candidate wells are not effective. In mid-2000, the U.S. Department of Energy (DOE) awarded ARI an R&D contract to determine if the methods employed in that project could also be applied to stripper gas wells. In addition, the ability of those approaches to identify more general production enhancement opportunities (beyond only restimulation), such as via artificial lift and compression, was also sought. A key challenge in this effort was that, whereas the earlier work suggested that better (producing) wells tended to make better restimulation candidates, stripper wells are by definition low-volume producers (either due to low pressure, low permeability, or both). Nevertheless, the potential application of this technology was believed to hold promise for enhancing production for the thousands of stripper gas wells that exist in the U.S. today. The overall procedure for the project was to select a field test site, apply the candidate recognition methodology to select wells for remediation, remediate them, and gauge project success based on the field results. This report summarizes the activities and results of that project.

Optimization of fractured well performance of horizontal gas wells  

E-Print Network (OSTI)

In low-permeability gas reservoirs, horizontal wells have been used to increase the reservoir contact area, and hydraulic fracturing has been further extending the contact between wellbores and reservoirs. This thesis presents an approach to evaluate horizontal well performance for fractured or unfractured gas wells and a sensitivity study of gas well performance in a low permeability formation. A newly developed Distributed Volumetric Sources (DVS) method was used to calculate dimensionless productivity index for a defined source in a box-shaped domain. The unique features of the DVS method are that it can be applied to transient flow and pseudo-steady state flow with a smooth transition between the boundary conditions. In this study, I conducted well performance studies by applying the DVS method to typical tight sandstone gas wells in the US basins. The objective is to determine the best practice to produce horizontal gas wells. For fractured wells, well performance of a single fracture and multiple fractures are compared, and the effect of the number of fractures on productivity of the well is presented based on the well productivity. The results from this study show that every basin has a unique ideal set of fracture number and fracture length. Permeability plays an important role on dictating the location and the dimension of the fractures. This study indicated that in order to achieve optimum production, the lower the permeability of the formation, the higher the number of fractures.

Utilization of melting techniques for borehole wall stabilization. [Applied to geothermal well production systems  

DOE Green Energy (OSTI)

A research program on the Subterrene concept based on excavation by melting has been completed. Theoretical and experimental studies were made for a broad range of applications. Most recently, a study of Subterrene deep geothermal well production systems predicted that, compared to rotary-drilled wells, significant cost savings are possible, e.g., 2 and 4 million dollars for 10-km-deep wells and geothermal gradients of 25 and 40 K/km, respectively. It was also concluded that for most wells the rate of penetration of the melting bits should be increased several times over that attained in the Subterrene tests. Subterrene melting penetration tests showed that borehole glass liners can be formed in a wide variety of materials and structural characterization tests showed that tuff glass cylinders can be many times stronger in compression than the parent material. Also, the tests showed that the rock-glass liner permeability decreases rapidly with confining pressure. New melting devices are conceivable that could line rotary-drilled boreholes with rock glass or other materials with resultant improvements in well costs. With emphasis on borehole liners, an overview of Subterrene program results, data on rock-glass liners, and suggestions on how molten materials might be applied to the borehole wall as part of a rotary drilling operation are presented.

Minute durable plate-like thermal indicators are employed for precision measuring static and dynamic temperatures of well drilling fluids. The indicators are small enough and sufficiently durable to be circulated in the well with drilling fluids during the drilling operation. The indicators include a heat resistant indicating layer, a coacting meltable solid component and a retainer body which serves to unitize each indicator and which may carry permanent indicator identifying indicia. The indicators are recovered from the drilling fluid at ground level by known techniques.

Evaluation of polymer free drill-in fluids for use in high productivity, horizontal well completions  

E-Print Network (OSTI)

Advancements in deepwater drilling have necessitated the use of more specialized reservoir drill-in fluids (RDIF). These RDIFs must exhibit unique rheological properties while minimizing formation damage. Xanthan gum biopolymer is generally used as a primary viscosifier in RDIFs. In high salinity brines the high shear rate viscosity that xanthan gum provides can approach levels that could exceed the fracture gradient of the well. Therefore, it is important to maintain a xanthan gum concentration that keeps the equivalent circulating density at a modest level. Reducing the xanthan gum level, however, compromises the hole cleaning properties that the low- shear-rate viscosity provides. Xanthan gum biopolymers are also associated with formation damage, which inhibits the flow of oil and gas during production. A new RDIF, which utilizes no xanthan gum biopolymer, has been recently developed. The new product uses a starch instead of polymer to develop rheological properties. This fluid will primarily be targeted for production zone drilling in highly deviated and horizontal wells. This research focused on filtercake cleanup and the reduced formation damage associated with this biopolymer-free fluid. The behavior of the polymer free fluid was analyzed developing tests at different temperatures, at different drill solids content, and with different treatment fluids. The laboratory methods used were a ceramic disc cell and a linear flow cell. The former will permit an analysis of the time that a certain cleaning treatment takes to flow through a filter cake. The latter simulates well completions in unconsolidated horizontal well reservoirs permitting the estimation of formation damage produced by drilling and completion fluids and the effectiveness of the cleaning treatment applied. Multivariate statistical analysis was performed with the experimental results obtained. Comparison with conventional RDIF data from polymer carbonate and sized salt fluids provided informative contrasts in performance.

Regional long-term production modeling from a single well test, Mount Elbert Gas Hydrate Stratigraphic Test Well, Alaska North Slope  

Science Conference Proceedings (OSTI)

Following the results from the open-hole formation pressure response test in the BPXA-DOE-USGS Mount Elbert Gas Hydrate Stratigraphic Test Well (Mount Elbert well) using Schlumberger’s Modular Dynamics Formation Tester (MDT) wireline tool, the International Methane Hydrate Reservoir Simulator Code Comparison project performed long-term reservoir simulations on three different model reservoirs. These descriptions were based on 1) the Mount Elbert gas hydrate accumulation as delineated by an extensive history-matching exercise, 2) an estimation of the hydrate accumulation near the Prudhoe Bay L-pad, and 3) a reservoir that would be down-dip of the Prudhoe Bay L-pad and therefore warmer and deeper. All of these simulations were based, in part, on the results of the MDT results from the Mount Elbert Well. The comparison group’s consensus value for the initial perme- ability of the hydrate-filled reservoir (k = 0.12 mD) and the permeability model based on the MDT history match were used as the basis for subsequent simulations on the three regional scenarios. The simulation results of the five different simulation codes, CMG STARS, HydrateResSim, MH-21 HYDRES, STOMP-HYD, and TOUGHþHYDRATE exhibit good qualitative agreement and the variability of potential methane production rates from gas hydrate reservoirs is illustrated. As expected, the pre- dicted methane production rate increased with increasing in situ reservoir temperature; however, a significant delay in the onset of rapid hydrate dissociation is observed for a cold, homogeneous reservoir and it is found to be repeatable. The inclusion of reservoir heterogeneity in the description of this cold reservoir is shown to eliminate this delayed production. Overall, simulations utilized detailed information collected across the Mount Elbert reservoir either obtained or determined from geophysical well logs, including thickness (37 ft), porosity (35%), hydrate saturation (65%), intrinsic permeability (1000 mD), pore water salinity (5 ppt), and formation temperature (3.3–3.9 ?C). This paper presents the approach and results of extrapolating regional forward production modeling from history-matching efforts on the results from a single well test.

Acid-sludge characterization and remediation improve well productivity and save costs in the Permian Basin  

SciTech Connect

Many oil wells in the Permian Basin have reported sludging problems associated with acid stimulations. The acid sludge is similar among wells and was identified as a viscous emulsion stabilized by asphaltene-rich organic solids. The sludging tendency of the oil increased with the concentrations of asphaltenes and resins, base number of the oil, and ferric ion content in the acid. Only three out of nine commercial acid systems tested were effective in preventing acid-sludge formation; they all use the same novel iron control technology, i.e., catalytic reduction of ferric ions. Several commercial and generic solvent systems were effective in dissolving acid sludge, including mixtures of an aromatic solvent (e.g., xylene) with either isopropyl alcohol (2:1 volume ratio), or ethylene glycol-monobutylether (EGMBE) (2:1 to 3:1 volume ratios). Selection of acid formulations and solvent systems was based on cost effectiveness and operation safety. Field implementation proved successful. If the results of this study had been implemented earlier in the lives of some of the Permian Basin properties, the recovery of 574 BOPD of lost or deferred production from 99 wells could have been realized. This would have resulted in an estimated increased revenue of over US $3 million in 1 year.

City of North Bonneville, Washington: Geothermal Exploration Project, production test well, Phase II. Final report  

SciTech Connect

Based on discussions with the City of North Bonneville, the production test well was drilled to a depth that would also explore for ground water temperatures near 130/sup 0/F (54.4/sup 0/C). Depth projections to a 130/sup 0/F bottom hole temperature were made by assuming a constant ground water temperature rise greater than 50/sup 0/C per kilometer, and by assuming that essentially homogeneous or equivalent conductive rock units would be encountered. Minimum water production requirements were not set, although the City determined that about 800 gpm would be acceptable. Large upper casing diameters of 16 and 12 inches were installed in order to provide the future use of either a vertical turbine or submersible pump, as desired by the city. The scope of work included interpretation of well characteristics, evaluation of ground water as a geothermal resource, geologic analysis of data from drilling and testing, drilling supervision, daily drilling cost accounting, and preparation of a final report. The report includes geologic evaluation of the drilling and test data, ground water and geothermal potential.

Cementing horizontal wells  

SciTech Connect

Since the introduction of horizontal drilling, most completions have been open hole. Open-hole or slotted-liner completions may be satisfactory in straight, thick formations, if stimulation is not required. But if the wellbore wanders out of the reservoir, whether due to loss of directional control or spotty knowledge of formation dimensions, casing becomes a necessity. In addition, a wellbore that stays in the formation but comes uncomfortably close to the water-oil contact or gas cap requires casing to prevent coning. Further, if stimulation is anticipated, or may become a necessity, it is essential that the hole be cased and cemented. Otherwise, there is no control of the stimulation treatment. Even if the horizontal wellbore itself does not require casing, intermediate casing in the high-angle hole is needed. This is especially critical in open-hole completions below a gas cap, for example. The keys to effective horizontal cementing are fundamentally the same as for cementing vertical wells: proper centralization of casing in the bore-hole to ensure efficient mud removal and well-designed cement slurries.

Evidence of Reopened Microfractures in Production Data of Hydraulically Fractured Shale Gas Wells  

E-Print Network (OSTI)

Frequently a discrepancy is found between the stimulated shale volume (SSV) estimated from production data and the SSV expected from injected water and proppant volume. One possible explanation is the presence of a fracture network, often termed fracture complexity, that may have been opened or reopened during the hydraulic fracturing operation. The main objective of this work is to investigate the role of fracture complexity in resolving the apparent SSV discrepancy and to illustrate whether the presence of reopened natural fracture network can be observed in pressure and production data of shale gas wells producing from two shale formations with different well and reservoir properties. Homogeneous, dual porosity and triple porosity models are investigated. Sensitivity runs based on typical parameters of the Barnett and the Horn River shale are performed. Then the field data from the two shales are matched. Homogeneous models for the two shale formations indicate effective infinite conductivity fractures in the Barnett well and only moderate conductivity fractures in the Horn River shale. Dual porosity models can support effectively infinite conductivity fractures in both shale formations. Dual porosity models indicate that the behavior of the Barnett and Horn River shale formations are different. Even though both shales exhibit apparent bilinear flow behavior the flow behaviors during this trend are different. Evidence of this difference comes from comparing the storativity ratio observed in each case to the storativity ratio estimated from injected fluid volumes during hydraulic fracturing. In the Barnett shale case similar storativity ratios suggest fracture complexity can account for the dual porosity behavior. In the Horn River case, the model based storativity ratio is too large to represent only fluids from hydraulic fracturing and suggests presence of existing shale formation microfractures.

Fundamentals of horizontal well completions  

Science Conference Proceedings (OSTI)

Oil and gas wells are drilled horizontally for a variety of reasons, chiefly to improve production without drilling multiple vertical wells and to prevent water or gas coning. Benefits of horizontal drilling are well documented. This article addresses the fundamentals of completing a horizontal well, discussing completion by (1) open hole, (2) casing packers, (3) slotted or perforated liner, and (4) cemented casing/liner. Completion methods 1 through 3 are generally known as ''drain hole'' completions, and method 4 is commonly called the ''case hole'' or ''stimulated'' completion.

Geothermal Power Production from Brine Co-Produced from Oil and Gas Wells  

Science Conference Proceedings (OSTI)

Millions of barrels of water (brine) per day are co-produced from oil and gas wells. Currently, the oil and gas industry views this as a waste stream that costs millions of dollars per year to manage, through either treatment or disposal/reinjection. A significant percentage of the co-produced brine, however, flows at sufficient rate and temperature to generate power using a binary power plant, and this is viewed by some as a potential value stream. The value lies in that the co-produced water is "free" ...

Multi-Seam Well Completion Technology: Implications for Powder River Basin Coalbed Methane Production  

Science Conference Proceedings (OSTI)

The purpose of this study is to evaluate the potential benefits of applying multiseam [well] completion (MSC) technology to the massive stack of low-rank coals in the Powder River Basin. As part of this, the study objectives are: Estimate how much additional CBM resource would become accessible and technically recoverable--compared to the current practice of drilling one well to drain a single coal seam; Determine whether there are economic benefits associated with MSC technology utilization (assuming its widespread, successful application) and if so, quantify the gains; Briefly examine why past attempts by Powder River Basin CBM operators to use MSC technology have been relatively unsuccessful; Provide the underpinnings to a decision whether a MSC technology development and/or demonstration effort is warranted by DOE. To a great extent, this assessment builds on the previously published study (DOE, 2002), which contains many of the key references that underlie this analysis. It is available on the U.S. Department of Energy, National Energy technology Laboratory, Strategic Center for Natural Gas website (www.netl.doe.gov/scng). It is suggested that readers obtain a copy of the original study to complement the current report.

What's new in well control  

Science Conference Proceedings (OSTI)

Drillers know that the most important tools used in well control are preparation and knowledge. That fact is reinforced by government agency requirements for certification of responsible people on the rig, particularly in sensitive public areas like offshore waters. And existing problems like shallow gas blowouts and kick control in conventional wells have been complicated by industry's move to horizontal wells and underbalanced drilling. The International Association of Drilling Contractors (IADC) in the US and Europe is devoting a major effort to well control technology. It sponsored a comprehensive conference in Houston in November 1993, plus a well control trainer's Roundtable meeting in Houston in March. The IADC Well Control Conference for Europe is scheduled for June 8--10, 1994, in Stavanger, Norway, with an important 22-paper program. In this article, World Oil has selected several presentations from the two US IADC conferences noted above. These selections are noted by the authors as being of wide and current interest to the industry, they include: (1) horizontal well considerations, (2) a proposed new well killing method, (3) underbalanced drilling, (4) a new onsite simulator, and (5) IADC's school accreditation program. Summaries shown here cover only major topics. Original papers should be consulted for important details.

Geothermal Well Site Restoration and Plug and Abandonment of Wells  

DOE Green Energy (OSTI)

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

ADVANCED CEMENTS FOR GEOTHERMAL WELLS  

Science Conference Proceedings (OSTI)

Using the conventional well cements consisting of the calcium silicate hydrates (CaO-SiO{sub 2}-H{sub 2}O system) and calcium aluminum silicate hydrates (CaO-Al{sub 2}O{sub 3}-SiO{sub 2}-H{sub 2}O system) for the integrity of geothermal wells, the serious concern confronting the cementing industries was their poor performance in mechanically supporting the metallic well casing pipes and in mitigating the pipe's corrosion in very harsh geothermal reservoirs. These difficulties are particularly acute in two geological regions: One is the deep hot downhole area ({approx} 1700 m depth at temperatures of {approx} 320 C) that contains hyper saline water with high concentrations of CO{sub 2} (> 40,000 ppm) in conjunction with {approx} 100 ppm H{sub 2}S at a mild acid of pH {approx} 5.0; the other is the upper well region between the well's surface and {approx} 1000 m depth at temperatures up to 200 C. The specific environment of the latter region is characterized by highly concentrated H{sub 2}SO{sub 4} (pH strength of cements, lowering the mechanical support of casing pipes, but also increased the extent of permeability of the brine through the cement layer, promoting the rate of the pipe's corrosion. Severely carbonated and acid eroded cements often impaired the integrity of a well in less than one year; in the worst cases, casings have collapsed within three months, leading to the need for costly and time-consuming repairs or redrilling operations. These were the reasons why the geothermal well drilling and cementing industries were concerned about using conventional well cements, and further their deterioration was a major impediment in expediting the development of geothermal energy resources.

Geothermal energy well casing seal  

SciTech Connect

A geothermal energy transfer and utilization system makes use of thermal energy stored in hot solute-bearing well water to generate super-heated steam from an injected flow of clean water. The super-heated steam is then used for operating a turbine-driven pump at the well bottom for pumping the hot solute-bearing water at high pressure and in liquid state to the earth's surface, where it is used by transfer of its heat to a closed-loop steam generator-turbine-alternator combination for the beneficial generation of electrical or other power. Residual concentrated solute-bearing water is pumped back into the earth. The clean cooled water regenerated at the surface-located system is returned to the deep well pumping system also for lubrication of a fluid bearing arrangement supporting the turbine-driven pump system. The deep well pump system is supported within the well casing pipe from the earth's surface by the turbine exhaust steam conduit. In view of differential expansion effects on the relative lengths of the casing pipe and the exhaust steam conduit, a novel flexible seal is provided between the suspended turbine-pump system and the well pipe casing. 9 claims, 2 drawing figures.

ESTABLISHMENT OF AN INDUSTRY-DRIVEN CONSORTIUM FOCUSED ON IMPROVING THE PRODUCTION PERFORMANCE OF DOMESTIC STRIPPER WELLS  

SciTech Connect

The Pennsylvania State University, under contract to the US Department of Energy, National Energy Technology Laboratory will establish, promote, and manage a national industry-driven Stripper Well Consortium (SWC) that will be focused on improving the production performance of domestic petroleum and/or natural gas stripper wells. the consortium creates a partnership with the US petroleum and natural gas industries and trade associations, state funding agencies, academia, and the National Energy Technology Laboratory. This report serves as the third quarterly technical progress report for the SWC. During this reporting period the SWC entered into a co-funding arrangement with the New York State Energy Development Authority (NYSERDA) to provide an additional $100,000 in co-funding for stripper well production-orientated projects.The SWC hosted its first meeting in which members proposed research projects to the SWC membership. The meeting was held on April 9-10, 2001 in State College, Pennsylvania. Twenty three proposals were submitted to the SWC for funding consideration. Investigators of the proposed projects provided the SWC membership with a 20 minute (15 minute technical discussion, 5 minute question and answer session) presentation. Of the 23 proposals, the Executive Council approved $921,000 in funding for 13 projects. Penn State then immediately started the process of issuing subcontracts to the various projects approved for funding.

ADVANCED CEMENTS FOR GEOTHERMAL WELLS  

DOE Green Energy (OSTI)

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

Temperature histories in geothermal wells: survey of rock thermomechanical properties and drilling, production, and injection case studies  

DOE Green Energy (OSTI)

Thermal and mechanical properties for geothermal formations are tabulated for a range of temperatures and stress conditions. Data was obtained from the technical literature and direct contacts with industry. Thermal properties include heat capacity, conductivity, and diffusivity. Undisturbed geothermal profiles are also presented. Mechanical properties include Youngs modulus and Poisson ratio. GEOTEMP thermal simulations of drilling, production and injection are reported for two geothermal regions, the hot dry rock area near Los Alamos and the East Mesa field in the Imperial Valley. Actual drilling, production, and injection histories are simulated. Results are documented in the form of printed GEOTEMP output and plots of temperatures versus depth, radius, and time. Discussion and interpretation of the results are presented for drilling and well completion design to determine: wellbore temperatures during drilling as a function of depth; bit temperatures over the drilling history; cement temperatures from setting to the end of drilling; and casing and formation temperatures during drilling, production, and injection.

DOE Geothermal well stimulation program  

DOE Green Energy (OSTI)

An effective stimulation treatment requires the interaction of four separate items: frac fluids, proppants, equipment, and planned and properly engineered schedules. While there are good fluid systems and proppants, only judicious combinations and a well thought out schedule which uses all of these materials and available equipment to best advantage is an optimum stimulation treatment. Generally, high flow rates and convective cooling can be used either with conventional (planar) fracturing or with a dendritic fracturing technique. Many of todays fluid systems have been tested to above 400/sup 0/F. Some fluids have survived quite well. Current tests on proppants have shown temperature sensitivities in sand; however, there are resin coated materials and sintered bauxite which are not temperature sensitive. (MHR)

Improved geothermal well logging tools  

DOE Green Energy (OSTI)

A geothermal well logging tool has been designed to operate at 275/sup 0/C and 7000 psi. The logging tool will initially consist of a manometer, a gradiomanometer and a thermometer; the electrical and mechanical design is such that a flowmeter and a caliper can be added as a later development. A unique feature of the logging tool is that it contains no downhole active electronics. The manometer is a standard high temperature pressure gauge. The gradiomanometer consists of a differential pressure gauge which is coupled to ports separated vertically by 2 ft. The differential pressure gauge is a new development; it is designed to measure a differential pressure up to 2 psi at a line pressure of 10,000 psi. The thermometer is a platinum resistance thermometer previously developed for oil well logging. The pressure gauges are both strain gauge types which allows all three gauges are both strain gauge types which allows all three gauges to be connected in series and driven from a constant current supply. This arrangement makes it possible to use a standard seven-conductor cable with no downhole switching. The joints in the sonde are electron beam welded, thus eliminating any sealed joints in the sonde wall. The logging tool will be tested first in an autoclave and in a geothermal well later in the program.

Well simulation using Refrigerant 114  

DOE Green Energy (OSTI)

A simple method for the investigation of thermodynamic (substance) similarity in the two-phase domain is introduced based on the assumptions of a simplified model fluid. According to this method, the investigation of the conditions for thermodynamic similarity between substances in the two-phase region reveals the important role the latent heat of evaporation (h/sub fg/) plays in the definition of the property scales. These greatly influence the dynamic and geometric similarity of the process under investigation. The introduction of the thermodynamic similarity property scales into the energy conservation equations for a certain process (e.g., flow up a geothermal well) brings forth a thermodynamic length scale and kinetic energy scale. Refrigerant 114 has been examined for similarity with water substance according to this method and found to be adequate for geothermal well simulation in the laboratory. Low pressures and temperatures and a substantial reduction of mass flow rates and geometric scales are a few of the advantages of using R114 for such experiments.

Preliminary study of discharge characteristics of slim holes compared to production wells in liquid-dominated geothermal reservoirs  

DOE Green Energy (OSTI)

There is current interest in using slim holes for geothermal exploration and reservoir assessment. A major question that must be addressed is whether results from flow or injection testing of slim holes can be scaled to predict large diameter production well performance. This brief report describes a preliminary examination of this question from a purely theoretical point of view. The WELBOR computer program was used to perform a series of calculations of the steady flow of fluid up geothermal boreholes of various diameters at various discharge rates. Starting with prescribed bottomhole conditions (pressure, enthalpy), the WELBOR code integrates the equations expressing conservation of mass, momentum and energy (together with fluid constitutive properties obtained from the steam tables) upwards towards the wellhead using numerical techniques. This results in computed profiles of conditions (pressure, temperature, steam volume fraction, etc.) as functions of depth within the flowing well, and also in a forecast of wellhead conditions (pressure, temperature, enthalpy, etc.). From these results, scaling rules are developed and discussed.

Ultra Thin Quantum Well Materials  

Science Conference Proceedings (OSTI)

This project has enabled Hi-Z technology Inc. (Hi-Z) to understand how to improve the thermoelectric properties of Si/SiGe Quantum Well Thermoelectric Materials. The research that was completed under this project has enabled Hi-Z Technology, Inc. (Hi-Z) to satisfy the project goal to understand how to improve thermoelectric conversion efficiency and reduce costs by fabricating ultra thin Si/SiGe quantum well (QW) materials and measuring their properties. In addition, Hi-Z gained critical new understanding on how thin film fabrication increases the silicon substrate's electrical conductivity, which is important new knowledge to develop critical material fabrication parameters. QW materials are constructed with alternate layers of an electrical conductor, SiGe and an electrical insulator, Si. Film thicknesses were varied, ranging from 2nm to 10nm where 10 nm was the original film thickness prior to this work. The optimum performance was determined at a Si and SiGe thickness of 4nm for an electrical current and heat flow parallel to the films, which was an important conclusion of this work. Essential new information was obtained on how the Si substrate electrical conductivity increases by up to an order of magnitude upon deposition of QW films. Test measurements and calculations are accurate and include both the quantum well and the substrate. The large increase in substrate electrical conductivity means that a larger portion of the electrical current passes through the substrate. The silicon substrate's increased electrical conductivity is due to inherent impurities and thermal donors which are activated during both molecular beam epitaxy and sputtering deposition of QW materials. Hi-Z's forward looking cost estimations based on future high performance QW modules, in which the best Seebeck coefficient and electrical resistivity are taken from separate samples predict that the electricity cost produced with a QW module could be achieved at price would open many markets for waste heat recovery applications. By installing Hi-Z's materials in applications in which electricity could be produced from waste heat sources could result in significant energy savings as well as emissions reductions. For example, if QW thermoelectric generators could be introduced commercially in 2015, and assuming they could also capture an additional 0.1%/year of the available waste heat from the aluminum, steel, and iron industries, then by 2020, their use would lead to a 2.53 trillion Btu/year reduction in energy consumption. This translates to a $12.9 million/year energy savings, and 383.6 million lb's of CO2 emissions reduction per year. Additionally, Hi-Z would expect that the use of QW TE devices in the automotive, manufacturing, and energy generation industries would reduce the USA's petroleum and fossil fuel dependence, and thus significantly reduce emissions from CO2 and other polluting gasses such as NOx, SOx, and particulate matter (PM), etc.

Bachaquero-01 reservoir, Venezuela-increasing oil production by switching from cyclic steam injection to steamflooding using horizontal wells  

E-Print Network (OSTI)

The Bachaquero-01 reservoir of the Lagunillas field is located in the eastern part of the Maracaibo Lake, Venezuela. The field is operated by the national oil company of Venezuela, PDVSA (Petroleos de Venezuela, S.A.). The Bachaquero-01 heavy oil reservoir lies at about 3,000 ft. ss. and contains 7.037 BSTB of 1 1.7 degrees API gravity oil with an in-situ viscosity of 635 cp. Cold production began in 1960, but since 1971 the reservoir was produced under a massive cyclic steam injection system. To-date some 370 cyclic-steam injection welts have produced from the reservoir, yielding a cumulative oil recovery of only about 5.6% of initial oil-in-place. The reservoir pressure has dropped from an initial 1,370 psia to its present value of about 700 psia. Maximum oil production peaked at 45.0 MSTB/D in 1991, and has since continued to decline. To arrest production decline, three horizontal cyclic-steam injection wells were drilled and completed in the reservoir in 1995-1997. The horizontal sections were from 1,280 to 1,560 ft long and were drilled in locations with existing vertical cyclic steam injection welts. Three-dimensional thermal-compositional simulation studies were conducted to evaluate the performance of the three horizontal welts under cyclic steam injection and steamflooding. The Cartesian model dimensions of the three horizontal welts were 11x22x4, 11x27x5, and 12x20x5. In the steamflooding scheme investigated, the existing horizontal welts were used as injectors while existing (and new) vertical welts surrounding the horizontal welts were used as producers. Simulation results indicate oil recovery under cyclic steam injection to be about 15% of initial oil-in-place, compared to about 25% under steamflooding with no new producers, and about 50% under steamflooding with additional producers. The main advantages of steamflooding over cyclic steam injection were in the re-pressurization and improved thermal efficiency for the Bachaquero-01 reservoir. Higher oil recovery with additional wells resulted from improved areal sweep efficiency. Further study is planned to investigate steamflooding for the rest of the reservoir.

Advanced Technologies For Stripper Gas Well Enhancement  

SciTech Connect

Stripper gas and oil well operators frequently face a dilemma regarding maximizing production from low-productivity wells. With thousands of stripper wells in the United States covering extensive acreage, it is difficult to identify easily and efficiently marginal or underperforming wells. In addition, the magnitude of reviewing vast amounts of data places a strain on an operator's work force and financial resources. Schlumberger DCS, in cooperation with the National Energy Technology Laboratory (NETL) and the U.S. Department of Energy (DOE), has created software and developed in-house analysis methods to identify remediation potential in stripper wells relatively easily. This software is referred to as Stripper Well Analysis Remediation Methodology (SWARM). SWARM was beta-tested with data pertaining to two gas fields located in northwestern Pennsylvania and had notable results. Great Lakes Energy Partners, LLC (Great Lakes) and Belden & Blake Corporation (B&B) both operate wells in the first field studied. They provided data for 729 wells, and we estimated that 41 wells were candidates for remediation. However, for reasons unbeknownst to Schlumberger these wells were not budgeted for rework by the operators. The second field (Cooperstown) is located in Crawford, Venango, and Warren counties, Pa and has more than 2,200 wells operated by Great Lakes. This paper discusses in depth the successful results of a candidate recognition study of this area. We compared each well's historical production with that of its offsets and identified 339 underperformers before considering remediation costs, and 168 economically viable candidates based on restimulation costs of $50,000 per well. From this data, we prioritized a list based on the expected incremental recoverable gas and 10% discounted net present value (NPV). For this study, we calculated the incremental gas by subtracting the volumes forecasted after remediation from the production projected at its current configuration. Assuming that remediation efforts increased production from the 168 marginal wells to the average of their respective offsets, approximately 6.4 Bscf of gross incremental gas with a NPV approximating $4.9 million after investment, would be made available to the domestic market. Seventeen wells have successfully been restimulated to date and have already obtained significant production increases. At the time of this report, eight of these wells had enough post-rework production data available to forecast the incremental gas and verify the project's success. This incremental gas is estimated at 615 MMscf. The outcome of the other ten wells will be determined after more post-refrac production data becomes available. Plans are currently underway for future restimulations. The success of this project has shown the value of this methodology to recognize underperforming wells quickly and efficiently in fields containing hundreds or thousands of wells. This contributes considerably to corporate net income and domestic natural gas and/or oil reserves.

Economic evaluation of smart well technology  

E-Print Network (OSTI)

The demand of oil and gas resources is high and the forecasts show a trend for higher requirements in the future. More unconventional resource exploitation along with an increase in the total recovery in current producing fields is required. At this pivotal time the role of emerging technologies is of at most importance. Smart or intelligent well technology is one of the up and coming technologies that have been developed to assist improvements in field development outcome. In this paper a comprehensive review of this technology has been discussed. The possible reservoir environments in which smart well technology could be used and also, the possible benefits that could be realized by utilizing smart well technology has been discussed. The economic impact of smart well technology has been studied thoroughly. Five field cases were used to evaluate the economics of smart well technology in various production environments. Real field data along with best estimate of smart well technology pricings were used in this research. I have used different comparisons between smart well cases and conventional completion to illustrate the economic differences between the different completion scenarios. Based on the research, I have realized that all the smart well cases showed a better economic return than conventional completions. The offshore cases showed a good economic environment for smart well technology. Large onshore developments with smart well technology can also provide a lucrative economic return. These situations can increase the overall economic return and ultimate recovery which will assist in meeting some of the oil demand around the globe.

San Bernardino National Wildlife Refuge Well 10  

Science Conference Proceedings (OSTI)

The U.S. Geological Survey (USGS), at the request of the U.S. Fish and Wildlife Service, evaluated the water production capacity of an artesian well in the San Bernardino National Wildlife Refuge, Arizona. Water from the well initially flows into a pond containing three federally threatened or endangered fish species, and water from this pond feeds an adjacent pond/wetland containing an endangered plant species.

Sand-control alternatives for horizontal wells

This paper reports that it has been well documented that horizontal completions increase production rates, as much as two to five times those of conventional techniques, because more of the producing formation is exposed to the wellbore. Although productivity improvements are highly sensitive to reservoir parameters, it is becoming generally accepted that optimum horizontal lengths will be 2,000 to 4,000 ft. The length of these completions generally causes the velocity of the fluid at the sandface to be an order of magnitude less than that observed in conventional completions. Because drag forces contributed to sand production, horizontal wells can produce at higher sand-free flow rates than conventional completions in the same reservoir. While it is frequently argued that horizontal wells do not need sand control, the potential for sand production increases significantly as reserves deplete and rock stresses increase. This is becoming more evident today in several major North Sea oil fields with conventional completions. Also, many unconsolidated formations produce sand for the first time with the onset of water production, a typical problem in such areas as the Gulf of Mexico. Operators must decide whether to implement sand control in the original horizontal-completion program because of an immediate concern or because the potential exists for a problem to arise as the well matures.

MARGINAL EXPENSE OIL WELL WIRELESS SURVEILLANCE MEOWS  

SciTech Connect

A marginal expense oil well wireless surveillance system to monitor system performance and production from rod-pumped wells in real time from wells operated by Vaquero Energy in the Edison Field, Main Area of Kern County in California has been successfully designed and field tested. The surveillance system includes a proprietary flow sensor, a programmable transmitting unit, a base receiver and receiving antenna, and a base station computer equipped with software to interpret the data. First, the system design is presented. Second, field data obtained from three wells is shown. Results of the study show that an effective, cost competitive, real-time wireless surveillance system can be introduced to oil fields across the United States and the world.

Hydraulic fracturing and wellbore completion of coalbed methane wells in the Powder River Basin, Wyoming: Implications for water and gas production  

SciTech Connect

Excessive water production (more than 7000 bbl/month per well) from many coalbed methane (CBM) wells in the Powder River Basin of Wyoming is also associated with significant delays in the time it takes for gas production to begin. Analysis of about 550 water-enhancement activities carried out during well completion demonstrates that such activities result in hydraulic fracturing of the coal. Water-enhancement activities, consists of pumping 60 bbl of water/min into the coal seam during approximately 15 min. This is done to clean the well-bore and to enhance CBM production. Hydraulic fracturing is of concern because vertical hydraulic fracture growth could extend into adjacent formations and potentially result in excess CBM water production and inefficient depressurization of coals. Analysis of the pressure-time records of the water-enhancement tests enabled us to determine the magnitude of the least principal stress (S{sub 3}) in the coal seams of 372 wells. These data reveal that because S{sub 3} switches between the minimum horizontal stress and the overburden at different locations, both vertical and horizontal hydraulic fracture growth is inferred to occur in the basin, depending on the exact location and coal layer. Relatively low water production is observed for wells with inferred horizontal fractures, whereas all of the wells associated with excessive water production are characterized by inferred vertical hydraulic fractures. The reason wells with exceptionally high water production show delays in gas production appears to be inefficient depressurization of the coal caused by water production from the formations outside the coal. To minimize CBM water production, we recommend that in areas of known vertical fracture propagation, the injection rate during the water-enhancement tests should be reduced to prevent the propagation of induced fractures into adjacent water-bearing formations.

Enhance the well stimulation learning curve  

Science Conference Proceedings (OSTI)

This article explains that well a well is stimulated to either overcome formation damage or compensate for naturally poor permeability. Regardless of the motivation, it's a complicated process that requires considerable advanced planning and organization if mishaps are to be avoided. Well stimulation should be divided into three distinctly separate states, each with its own set of requirements. Perhaps the most important and difficult of the three stages, particularly during this economically depressed period, is justification. Does the well's expected increase in productivity warrant stimulation costs. How reliable is the production increase estimate. The second state is the actual execution of the stimulation. Quality control-quality assurance programs should be intact and, again, accountability assigned. The third stage of the stimulation process is evaluation after completion. Systems should be examined for efficiency breakdowns. If so, they should be corrected to prevent future problems. It is often necessary to keep a close watch on the well's performance for a considerable length of time before the stimulation's impact can be accurately judged.

Uncertainty analysis of well test data  

E-Print Network (OSTI)

During a well test a transient pressure response is created by a temporary change in production rate. The well response is usually monitored during a relatively short period of time, depending upon the test objectives. Reservoir properties are determined from well test data via an inverse problem approach. Uncertainty is inherent in any nonlinear inverse problem. Unfortunately, well test interpretation suffers particularly from a variety of uncertainties that, when combined, reduce the confidence that can be associated with the estimated reservoir properties. The specific factors that have been analyzed in this work are: 1. Pressure noise (random noise) 2. Pressure drift (systematic variation) 3. Rate history effects Our work is based on the analysis of the effects of random pressure noise, the drift error, and the rate history on the estimation of typical reservoir parameters for two common reservoir models: A vertical well with a constant wellbore storage and skin in a homogeneous reservoir. A vertical well with a finite conductivity vertical fracture including wellbore effects in a homogeneous reservoir. This work represents a sensitivity study of the impact of pressure and rate uncertainty on parameter estimation and the confidence intervals associated with these results. In this work we statistically analyze the calculated reservoir parameters to quantify the impact of pressure and rate uncertainty on them.

A study of production/injection data from slim holes and large-diameter wells at the Takigami Geothermal Field, Kyushu, Japan  

DOE Green Energy (OSTI)

Production and injection data from nine slim holes and sixteen large-diameter wells at the Takigami Geothermal Field, Kyushu, Japan were analyzed in order to establish relationships (1) between injectivity and productivity indices, (2) between productivity/injectivity index and borehole diameter, and (3) between discharge capacity of slim holes and large-diameter wells. Results are compared with those from the Oguni and Sumikawa fields. A numerical simulator (WELBOR) was used to model the available discharge rate from Takigami boreholes. The results of numerical modeling indicate that the flow rate of large-diameter geothermal production wells with liquid feedzones can be predicted using data from slim holes. These results also indicate the importance of proper well design.

Extreme overbalance perforating improves well performance  

Science Conference Proceedings (OSTI)

The application of extreme overbalance perforating, by Oryx Energy Co., is consistently outperforming the unpredictable, tubing-conveyed, underbalance perforating method which is generally accepted as the industry standard. Successful results reported from more than 60 Oryx Energy wells, applying this technology, support this claim. Oryx began this project in 1990 to address the less-than-predictable performance of underbalanced perforating. The goal was to improve the initial completion efficiency, translating it into higher profits resulting from earlier product sales. This article presents the concept, mechanics, procedures, potential applications and results of perforating using overpressured well bores. The procedure can also be used in wells with existing perforations if an overpressured surge is used. This article highlights some of the case histories that have used these techniques.

EVIDENCE OF TWO EXTREME FLOW REGIMES OPERATING I N THE PRODUCTION ZONE OF DIFFERENT WELLS FROM LOS AZUFRES  

SciTech Connect

A published method for calculating excess steam is modified in order to make it applicable to the case of a well producing fluid with a high non-condensable gas content. The method is applied to data from a number of wells from Los Azufres. The results show the expected linear relation between excess steam and the molar fraction of CO{sub 2} in the total discharge. The modified method also provides an estimate for the molar fraction of CO{sub 2} in the liquid phase of the reservoir. It is found that this concentration is relatively homogeneous in the southern section of the field, and seems to be slightly smaller in the deeper zones of the northern section. The calculated values of excess steam agree qualitatively, but not quantitatively, with values of steam quality in the undisturbed reservoir calculated by other authors. The calculation of excess steam tends to overestimate steam quality in cases where steam saturation in the reservoir is low, and has the opposite tendency when the steam quality in the reservoir is high. The first type of deviation is explained in terms of the effects of higher mobility of steam in the two-phase zone induced by pressure drawdown. The second type of deviation is explained as the result of boiling of liquid phase, and the consequent addition of (non-condensable) gas-poor steam to the flowing mass, also caused by the pressure drawdown. A necessary extension of the reasoning leading to these explanations, is the prediction that the non-condensable gas content in fluids produced from a reservoir with a high steam saturation, will either remain stable or decrease with time during exploitation.

Snubdrilling a new well in Venezuela  

Science Conference Proceedings (OSTI)

A new well was successfully drilled using a snubbing jack. The drill bit was rotated using a rotary table, downhole motors and combination of the two. Expected high-pressure zones prompted this use of ``snubdrilling.`` The primary objective was to drill a vertical well through underlying sands and gain information about formation pressures. This data would aid in the drilling of a relief well using a conventional drilling rig. The secondary objective was to relieve pressure by putting this new well on production. In addition to special high-pressure drilling jobs, there are other drilling applications where snubbing jacks are a feasible alternative to conventional rotary drilling rigs or coiled tubing units. Slimhole, underbalanced and flow drilling, and sidetracking of existing wells are excellent applications for snubdrilling. Advantages of snubdrilling vs. coiled tubing drilling, include ability to rotate drillstrings, use high-torque downhole motors, pump at high rates and pressures, apply significant overpull in case of stuck pipe, and run casing and liners without rigging down. Shortcomings of drilling with snubbing jacks compared to coiled tubing are the need to stop circulation while making new connections and inability to run continuous cable inside workstrings.

Helicopter magnetic survey conducted to locate wells  

Science Conference Proceedings (OSTI)

A helicopter magnetic survey was conducted in August 2007 over 15.6 sq mi at the Naval Petroleum Reserve No. 3’s (NPR-3) Teapot Dome Field near Casper, Wyoming. The survey’s purpose was to accurately locate wells drilled there during more than 90 years of continuous oilfield operation. The survey was conducted at low altitude and with closely spaced flight lines to improve the detection of wells with weak magnetic response and to increase the resolution of closely spaced wells. The survey was in preparation for a planned CO2 flood for EOR, which requires a complete well inventory with accurate locations for all existing wells. The magnetic survey was intended to locate wells missing from the well database and to provide accurate locations for all wells. The ability of the helicopter magnetic survey to accurately locate wells was accomplished by comparing airborne well picks with well locations from an intense ground search of a small test area.

Entiat 4Mile WELLs Completion Report, 2006.  

DOE Green Energy (OSTI)

The Entiat 4-mile Wells (Entiat 4-mile) project is located in the Entiat subbasin and will benefit Upper Columbia steelhead, spring Chinook and bull trout. The goal of this project is to prevent juvenile fish from being diverted into an out-of-stream irrigation system and to eliminate impacts due to the annual maintenance of an instream pushup dam. The objectives include eliminating a surface irrigation diversion and replacing it with two wells, which will provide Bonneville Power Administration (BPA) and the Bureau of Reclamation (Reclamation) with a Federal Columbia River Power System (FCRPS) BiOp metric credit of one. Wells were chosen over a new fish screen based on biological benefits and costs. Long-term biological benefits are provided by completely eliminating the surface diversion and the potential for fish entrainment in a fish screen. Construction costs for a new fish screen were estimated at $150,000, which does not include other costs associated with implementing and maintaining a fish screening project. Construction costs for a well were estimated at $20,000 each. The diversion consisted of a pushup dam that diverted water into an off-channel pond. Water was then pumped into a pressurized system for irrigation. There are 3 different irrigators who used water from this surface diversion, and each has multiple water right claims totaling approximately 5 cfs. Current use was estimated at 300 gallons per minute (approximately 0.641 cfs). Some irrigated acreage was taken out of orchard production less than 5 years ago. Therefore, approximately 6.8 acre-feet will be put into the State of Washington Trust Water Right program. No water will be set aside for conservation savings. The construction of the two irrigation wells for three landowners was completed in September 2006. The Lower Well (Tippen/Wick) will produce up to 175 gpm while the Upper Well (Griffith) will produce up to 275 gpm during the irrigation season. The eight inch diameter wells were developed to a depth of 75 feet and 85 feet, respectively, and will be pumped with Submersible Turbine pumps. The irrigation wells have been fitted with new electric boxes and Siemens flowmeters (MAG8000).

The Method of Distributed Volumetric Sources for Forecasting the Transient and Pseudo-steady State Productivity of Multiple Transverse Fractures Intersected by a Horizontal Well  

E-Print Network (OSTI)

This work of well performance modeling is focused on solving problems of transient and pseudo-steady state fluid flow in a rectilinear closed boundaries reservoir. This model has been applied to predict and to optimize gas production from a horizontal well intercepted by multiple transverse fractures in a bounded reservoir, and it also provides well-testing solutions. The well performance model is designed to provide enhanced efficiency with the same reliability for pressure transient analysis, and well performance prediction, especially in complex well fracture configuration. The principle is to simplify the calculation of the pressure response to an instantaneous withdraw, which happens in other fractures, within a shorter computational time. This pressure response is substituted with the interaction between the two whole fractures. This method is validated through comparison to results of rigorous Distributed Volumetric Sources (DVS) method in simple symmetric fracture configuration, and to results of field production data for complex well/fracture configuration of a tight gas reservoir. The results show a good agreement in both ways. This model indicates the capability to handle the situations, such as: various well drainages, asymmetry of the fracture wings, and curved horizontal well. The advantage of this well performance model is to provide faster processing - reducing the computational time as the number of fractures increase. Also, this approach is able to be applied as an optimization and screening tool to obtain the best fracture configurations for reservoir development of economically marginal fields, in terms of the number and dimensions of fractures per well, also with external economic and operational constraints.

The Devonian shale has been recognized as an important source of gas in the Appalachian Basin. The program aids producers in the collection of reservoir data not normally collected and assists in the evaluation of the effectiveness of zone selection and stimulation designs and methods. The study should provide a fuller understanding of the relationships that affect productivity in the Devonian shale. The relationships between gas flows and geological features that control the production characteristics in the Devonian shale are being developed.

GAS INJECTION/WELL STIMULATION PROJECT  

SciTech Connect

Driver Production proposes to conduct a gas repressurization/well stimulation project on a six well, 80-acre portion of the Dutcher Sand of the East Edna Field, Okmulgee County, Oklahoma. The site has been location of previous successful flue gas injection demonstration but due to changing economic and sales conditions, finds new opportunities to use associated natural gas that is currently being vented to the atmosphere to repressurize the reservoir to produce additional oil. The established infrastructure and known geological conditions should allow quick startup and much lower operating costs than flue gas. Lessons learned from the previous project, the lessons learned form cyclical oil prices and from other operators in the area will be applied. Technology transfer of the lessons learned from both projects could be applied by other small independent operators.

Lost Circulation Experience in Geothermal Wells  

DOE Green Energy (OSTI)

Lost circulation during drilling and cementing in geothermal wells is a problem common to most geothermal areas. Material and rig time costs due to lost circulation often represent one fourth or more of the total well cost. Assessment of the general drilling and completion practices commonly used for handling lost circulation have been surveyed and evaluated under a study sponsored by Sandia National Laboratories. Results of this study, including interviews with geothermal production companies and with drilling fluid service companies, are reported in the paper. Conclusions and recommendations are presented for control of lost circulation during geothermal operations. Recent improvements in lost circulation materials and techniques and potential equipment solutions to the lost circulation problem are discussed. Research needs are also identified.

Pumpernickel Valley Geothermal Project Thermal Gradient Wells  

DOE Green Energy (OSTI)

The Pumpernickel Valley geothermal project area is located near the eastern edge of the Sonoma Range and is positioned within the structurally complex Winnemucca fold and thrust belt of north-central Nevada. A series of approximately north-northeast-striking faults related to the Basin and Range tectonics are superimposed on the earlier structures within the project area, and are responsible for the final overall geometry and distribution of the pre-existing structural features on the property. Two of these faults, the Pumpernickel Valley fault and Edna Mountain fault, are range-bounding and display numerous characteristics typical of strike-slip fault systems. These characteristics, when combined with geophysical data from Shore (2005), indicate the presence of a pull-apart basin, formed within the releasing bend of the Pumpernickel Valley – Edna Mountain fault system. A substantial body of evidence exists, in the form of available geothermal, geological and geophysical information, to suggest that the property and the pull-apart basin host a structurally controlled, extensive geothermal field. The most evident manifestations of the geothermal activity in the valley are two areas with hot springs, seepages, and wet ground/vegetation anomalies near the Pumpernickel Valley fault, which indicate that the fault focuses the fluid up-flow. There has not been any geothermal production from the Pumpernickel Valley area, but it was the focus of a limited exploration effort by Magma Power Company. In 1974, the company drilled one exploration/temperature gradient borehole east of the Pumpernickel Valley fault and recorded a thermal gradient of 160oC/km. The 1982 temperature data from five unrelated mineral exploration holes to the north of the Magma well indicated geothermal gradients in a range from 66 to 249oC/km for wells west of the fault, and ~283oC/km in a well next to the fault. In 2005, Nevada Geothermal Power Company drilled four geothermal gradient wells, PVTG-1, -2, -3, and -4, and all four encountered geothermal fluids. The holes provided valuable water geochemistry, supporting the geothermometry results obtained from the hot springs and Magma well. The temperature data gathered from all the wells clearly indicates the presence of a major plume of thermal water centered on the Pumpernickel Valley fault, and suggests that the main plume is controlled, at least in part, by flow from this fault system. The temperature data also defines the geothermal resource with gradients >100oC/km, which covers an area a minimum of 8 km2. Structural blocks, down dropped with respect to the Pumpernickel Valley fault, may define an immediate reservoir. The geothermal system almost certainly continues beyond the recently drilled holes and might be open to the east and south, whereas the heat source responsible for the temperatures associated with this plume has not been intersected and must be at a depth greater than 920 meters (depth of the deepest well – Magma well). The geological and structural setting and other characteristics of the Pumpernickel Valley geothermal project area are markedly similar to the portions of the nearby Dixie Valley geothermal field. These similarities include, among others, the numerous, unexposed en echelon faults and large-scale pull-apart structure, which in Dixie Valley may host part of the geothermal field. The Pumpernickel Valley project area, for the majority of which Nevada Geothermal Power Company has geothermal rights, represents a geothermal site with a potential for the discovery of a relatively high temperature reservoir suitable for electric power production. Among locations not previously identified as having high geothermal potential, Pumpernickel Valley has been ranked as one of four sites with the highest potential for electrical power production in Nevada (Shevenell and Garside, 2003). Richards and Blackwell (2002) estimated the total heat loss and the preliminary production capacity for the entire Pumpernickel Valley geothermal system to be at 35MW.

Gas condensate damage in hydraulically fractured wells  

E-Print Network (OSTI)

This project is a research into the effect of gas condensate damage in hydraulically fractured wells. It is the result of a problem encountered in producing a low permeability formation from a well in South Texas owned by the El Paso Production Company. The well was producing a gas condensate reservoir and questions were raised about how much drop in flowing bottomhole pressure below dewpoint would be appropriate. Condensate damage in the hydraulic fracture was expected to be of significant effect. Previous attempts to answer these questions have been from the perspective of a radial model. Condensate builds up in the reservoir as the reservoir pressure drops below the dewpoint pressure. As a result, the gas moving to the wellbore becomes leaner. With respect to the study by El-Banbi and McCain, the gas production rate may stabilize, or possibly increase, after the period of initial decline. This is controlled primarily by the condensate saturation near the wellbore. This current work has a totally different approach. The effects of reservoir depletion are minimized by introduction of an injector well with fluid composition the same as the original reservoir fluid. It also assumes an infinite conductivity hydraulic fracture and uses a linear model. During the research, gas condensate simulations were performed using a commercial simulator (CMG). The results of this research are a step forward in helping to improve the management of gas condensate reservoirs by understanding the mechanics of liquid build-up. It also provides methodology for quantifying the condensate damage that impairs linear flow of gas into the hydraulic fracture.

Doublets and other allied well patterns  

Science Conference Proceedings (OSTI)

Whenever a liquid is injected into an infinite reservoir containing liquid with the same flow properties, the equations of flow are well known. The pressures in such a system vary over time and distance (radius) in ways that depend on the formation and liquid flow properties. Such equations are well known--they form the basis for the voluminous well-testing literature in petroleum engineering and ground water hydrology. Suppose there are two wells--one an injector and one a producer--with identical rates. The behavior of this system can be calculated using superposition; which merely means that the results can be added independently of each other. When this is done, the remarkable result is that after a period of time there is a region that approaches steady state flow. Thereafter, the pressures and flow velocities in this region stay constant. The size of this region increases with time. This ``steady state`` characteristic can be used to solve a number of interesting and useful problems, both in heat transfer and in fluid flow. The heat transfer problems can be addressed because the equations are identical in form. A number of such problems are solved herein for doublet systems. In addition, concepts are presented to help solve other cases that flow logically from the problems solved herein. It is not necessary that only two wells be involved. It turns out that any time the total injection and production are equal, the system approaches steady state. This idea is also addressed in these notes. A number of useful multiwell cases are addressed to present the flavor of such solutions.

Simple variational approaches to quantum wells  

E-Print Network (OSTI)

We discuss two simple variational approaches to quantum wells. The trial harmonic functions analyzed in an earlier paper give reasonable results for all well depths and are particularly suitable for deep wells. On the other hand, the exponential functions proposed here are preferable for shallow wells. We compare the shallow-well expansions for both kind of functions and show that they do not exhibit the cubic term appearing in the exact series. It is also shown that the deep-well expansion for the harmonic functions agree with the first terms of perturbation theory.

Treating paraffin deposits in producing oil wells  

Science Conference Proceedings (OSTI)

Paraffin deposition has been a problem for operators in many areas since the beginning of petroleum production from wells. An extensive literature search on paraffin problems and methods of control has been carried out, and contact was made with companies which provide chemicals to aid in the treatment of paraffin problems.

Deep Production Well for Geothermal Direct-Use Heating of A Large Commercial Greenhouse, Radium Springs, Rio Grande Rift, New Mexico  

DOE Green Energy (OSTI)

Expansion of a large commercial geothermally-heated greenhouse is underway and requires additional geothermal fluid production. This report discusses the results of a cost-shared U.S. Department of Energy (DOE) and A.R. Masson, Inc. drilling project designed to construct a highly productive geothermal production well for expansion of the large commercial greenhouse at Radium Springs. The well should eliminate the potential for future thermal breakthrough from existing injection wells and the inducement of inflow from shallow cold water aquifers by geothermal production drawdown in the shallow reservoir. An 800 feet deep production well, Masson 36, was drilled on a US Bureau of Land Management (BLM) Geothermal Lease NM-3479 at Radium Springs adjacent to the A. R. Masson Radium Springs Farm commercial greenhouse 15 miles north of Las Cruces in Dona Ana County, New Mexico just west of Interstate 25 near the east bank of the Rio Grande. The area is in the Rio Grande rift, a tectonically-active region with high heat flow, and is one of the major geothermal provinces in the western United State.

A combined perforating and well testing system  

Science Conference Proceedings (OSTI)

Underbalanced perforating is widely used in well completions and is considered by many operators to be an effective method of obtaining improved well productivity. A measurement of downhole pressure before, during and after perforating can be made by installing a pressure gauge on the gun-string. By using a wireline, the added capability of real-time read-out on surface allows the entire operation to be monitored 'live.' Correct underbalance can be accurately established prior to shooting, there is an unambiguous shot indication, and a pressure transient analysis can be made during the initial flow or fill-up period. From this we can obtain an estimate of permeability, skin damage and, possibly, static reservoir pressure, which is a useful supplement to the shut-in buildup analysis which usually follows if flow reaches surface. Any subsequent conventional well-test can of course be planned without the need to retrieve or run in additional equipment since the pressure gauge is already in place.

STIMULATION TECHNOLOGIES FOR DEEP WELL COMPLETIONS  

SciTech Connect

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

Gas condensate damage in hydraulically fractured wells  

E-Print Network (OSTI)

This project is a research into the effect of gas condensate damage in hydraulically fractured wells. It is the result of a problem encountered in producing a low permeability formation from a well in South Texas owned by the El Paso Production Company. The well was producing from a gas condensate reservoir. Questions were raised about whether flowing bottomhole pressure below dewpoint would be appropriate. Condensate damage in the hydraulic fracture was expected to be of significant effect. In the most recent work done by Adedeji Ayoola Adeyeye, this subject was studied when the effects of reservoir depletion were minimized by introduction of an injector well with fluid composition the same as the original reservoir fluid. He also used an infinite conductivity hydraulic fracture along with a linear model as an adequate analogy. He concluded that the skin due to liquid build-up is not enough to prevent lower flowing bottomhole pressures from producing more gas. This current study investigated the condensate damage at the face of the hydraulic fracture in transient and boundary dominated periods when the effects of reservoir depletion are taken into account. As a first step, simulation of liquid flow into the fracture was performed using a 2D 1-phase simulator in order to help us to better understand the results of gas condensate simulation. Then during the research, gas condensate models with various gas compositions were simulated using a commercial simulator (CMG). The results of this research are a step forward in helping to improve the management of gas condensate reservoirs by understanding the mechanics of liquid build-up. It also provides methodology for quantifying the condensate damage that impairs linear flow of gas into the hydraulic fracture.

Modeling well performance in compartmentalized gas reservoirs  

E-Print Network (OSTI)

Predicting the performance of wells in compartmentalized reservoirs can be quite challenging to most conventional reservoir engineering tools. The purpose of this research is to develop a Compartmentalized Gas Depletion Model that applies not only to conventional consolidated reservoirs (with constant formation compressibility) but also to unconsolidated reservoirs (with variable formation compressibility) by including geomechanics, permeability deterioration and compartmentalization to estimate the OGIP and performance characteristics of each compartment in such reservoirs given production data. A geomechanics model was developed using available correlation in the industry to estimate variable pore volume compressibility, reservoir compaction and permeability reduction. The geomechanics calculations were combined with gas material balance equation and pseudo-steady state equation and the model was used to predict well performance. Simulated production data from a conventional gas Simulator was used for consolidated reservoir cases while synthetic data (generated by the model using known parameters) was used for unconsolidated reservoir cases. In both cases, the Compartmentalized Depletion Model was used to analyze data, and estimate the OGIP and Jg of each compartment in a compartmentalized gas reservoir and predict the subsequent reservoir performance. The analysis was done by history-matching gas rate with the model using an optimization technique. The model gave satisfactory results with both consolidated and unconsolidated reservoirs for single and multiple reservoir layers. It was demonstrated that for unconsolidated reservoirs, reduction in permeability and reservoir compaction could be very significant especially for unconsolidated gas reservoirs with large pay thickness and large depletion pressure.

Simulation study of the effect of well spacing, effect of permeability anisotropy, and effect of Palmer and Mansoori model on coalbed methane production  

E-Print Network (OSTI)

Interference for adjacent wells may be beneficial to Coalbed-Methane production. The effect is the acceleration of de-watering which should lead to earlier and higher gas rate peaks. It is inherent that permeability anisotropy exists in the coalbed methane formation. It means that the placement of wells (wells configuration) has an effect on the development of coalbed methane field. The effect of Palmer-Mansoori Theory is increasing effective permeability at lower pressures due to matrix shrinkage during desorption. This effect should increase the gas recovery of coalbed methane production. Palmer and Mansoori model should be considered and included to coalbed methane reservoir simulation. These effects and phenomena can be modeled with the CMG simulator. A systematic sensitivity study of various reservoir and operating parameters will result in generalized guidelines for operating these reservoirs more effectively.

Potential hydrologic characterization wells in Amargosa Valley  

SciTech Connect

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

Geopressured-geothermal well activities in Louisiana  

DOE Green Energy (OSTI)

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

High order well-balanced schemes  

SciTech Connect

In this paper the authors review some recent work on high-order well-balanced schemes. A characteristic feature of hyperbolic systems of balance laws is the existence of non-trivial equilibrium solutions, where the effects of convective fluxes and source terms cancel each other. Well-balanced schemes satisfy a discrete analogue of this balance and are therefore able to maintain an equilibrium state. They discuss two classes of schemes, one based on high-order accurate, non-oscillatory finite difference operators which are well-balanced for a general class of equilibria, and the other one based on well-balanced quadratures, which can - in principle - be applied to all equilibria. Applications include equilibria at rest, where the flow velocity vanishes, and also the more challenging moving flow equilibria. Numerical experiments show excellent resolution of unperturbed as well as slightly perturbed equilibria.

Well test analysis in fractured media  

DOE Green Energy (OSTI)

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

Intervalley splittings of Si quantum wells  

E-Print Network (OSTI)

Multi-valley effective mass theory for silicon quantum well structure is studied taking into account the external fields and the quantum interfaces. It is found that the phenomenological delta function potential, employed to explain the valley splitting caused by the quantum well interface in the previous work [Ref. 10], can be derived self-consistently from the multi-valley effective mass theory. Finite element method is used to solve the multi-valley effective equations. Theoretical predictions are in a reasonably good agreement with the recent experimental observation of valley splitting in a SiO_{2}/Si/SiO_{2} quantum well, which prove the validity of our approach.

Well cost estimates in various geothermal regions  

DOE Green Energy (OSTI)

A project to estimate well costs in regions of current geothermal activity has been initiated. Costs associated with commonly encountered drilling problems will be included. Activity-based costing techniques will be employed to allow the identification of cost drivers and the evaluation of the economic effects of new technologies and operational procedures on well costs. The sensitivity of well costs to a number of parameters such as rate-of-penetration and daily operating costs will be examined. Additional sensitivity analyses and trade-off studies will evaluate the efficiency of various operational practices and preventive, as well as remedial, actions. These efforts should help provide an understanding of the consumption of resources in geothermal drilling.

Stimulation Technologies for Deep Well Completions  

SciTech Connect

The Department of Energy (DOE) is sponsoring the Deep Trek Program targeted at improving the economics of drilling and completing deep gas wells. Under the DOE program, Pinnacle Technologies is conducting a study to evaluate the stimulation of deep wells. The objective of the project is to assess U.S. deep well drilling and stimulation activity, review rock mechanics and fracture growth in deep, high-pressure/temperature wells and evaluate stimulation technology in several key deep plays. An assessment of historical deep gas well drilling activity and forecast of future trends was completed during the first six months of the project; this segment of the project was covered in Technical Progress Report No. 1. During the next six months, efforts were primarily split between summarizing rock mechanics and fracture growth in deep reservoirs and contacting operators about case studies of deep gas well stimulation as documented in Technical Progress Report No. 2. This report details work done with Anadarko and ChevronTexaco in the Table Rock Field in Wyoming.

Using Decline Map Anlaysis (DMA) to Test Well Completion Influence on Gas Production Decline Curves in Barnett Shale (Denton, Wise, and Tarrant Counties)  

E-Print Network (OSTI)

The increasing interest and focus on unconventional reservoirs is a result of the industry's direction toward exploring alternative energy sources. It is due to the fact that conventional reservoirs are being depleted at a fast pace. Shale gas reservoirs are a very favorable type of energy sources due to their low cost and long-lasting gas supply. In general, according to Ausubel (1996), natural gas serves as a transition stage to move from the current oil-based energy sources to future more stable and environment-friendly ones. By looking through production history in the U.S Historical Production Database, HPDI (2009), we learn that the Barnett Shale reservoir in Newark East Field has been producing since the early 90's and contributing a fraction of the U.S daily gas production. Zhao et al. (2007) estimated the Barnett Shale to be producing 1.97 Bcf/day of gas in 2007. It is considered the most productive unconventional gas shale reservoir in Texas. By 2004 and in terms of annual gas production volume, Pollastro (2007) considered the Barnett Shale as the second largest unconventional gas reservoir in the United States. Many studies have been conducted to understand better the production controls in Barnett Shale. However, this giant shale gas reservoir is still ambiguous. Some parts of this puzzle are still missing. It is not fully clear what makes the Barnett well produce high or low amounts of gas. Barnett operating companies are still trying to answer these questions. This study adds to the Barnett chain of studies. It tests the effects of the following on Barnett gas production in the core area (Denton, Wise, and Tarrant counties): * Barnett gross thickness, including the Forestburg formation that divides Barnett Shale. * Perforation footage. * Perforated zones of Barnett Shale. Instead of testing these parameters on each well production decline curve individually, this study uses a new technique to simplify this process. Decline Map Analysis (DMA) is introduced to measure the effects of these parameters on all production decline curves at the same time. Through this study, Barnett gross thickness and perforation footage are found not to have any definite effects on Barnett gas production. However, zone 3 (Top of Lower Barnett) and zone 1 (Bottom of Lower Barnett) are found to contribute to cumulative production. Zone 2 (Middle of Lower Barnett) and zone 4 (Upper Barnett), on the other hand, did not show any correlation or influence on production through their thicknesses.

Characterization Well R-7 Geochemistry Report  

Science Conference Proceedings (OSTI)

This report provides analytical results for four groundwater-sampling rounds conducted at characterization well R-7. The goal of the characterization efforts was to assess the hydrochemistry and to determine if contaminants from Technical Area (TA)-2 and TA-21 of the Los Alamos National Laboratory (LANL or the Laboratory) are present in the regional aquifer in the vicinity of the well. Figure 1.0-1 shows the well's location in the narrow upper part of Los Alamos Canyon, between the inactive Omega West reactor and the mouth of DP Canyon. Well R-7 is in an excellent location to characterize the hydrology and groundwater chemistry in both perched groundwater and the regional aquifer near sites of known Laboratory effluent release, including radionuclides and inorganic chemicals (Stone et al. 2002, 72717). The Risk Reduction and Environmental Stewardship-Remediation (RRES-R) Program (formerly the Environmental Restoration [ER] Project) installed well R-7 as part of groundwater investigations to satisfy requirements of the ''Hydrogeologic Workplan'' (LANL 1998, 59599) and to support the Laboratory's ''Groundwater Protection Management Program Plan'' (LANL 1996, 70215). Well R-7 was designed primarily to provide geochemical or water quality and hydrogeologic data for the regional aquifer within the Puye Formation. This report also presents a geochemical evaluation of the analytical results for well R-7 and provides hydrogeochemical interpretations using analytical results for groundwater samples collected at the well. Discussion of other hydrogeochemical data collected within the east-central portion of the Laboratory, however, is deferred until they can be evaluated in the context of sitewide information collected from other RRES and Hydrogeologic Workplan characterization wells (R-8A, R-9, and R-9i). Once all deep groundwater investigations in the east-central portion of the Laboratory are completed, geochemical and hydrogeologic conceptual models for the Los Alamos Canyon watershed may be included in a groundwater risk analysis. These models will include an evaluation of potential contaminant transport pathways. Well R-7 was completed on March 9, 2001, with three screens (363.2 to 379.2 ft, 730.4 to 746.4 ft, and 895.5 to 937.4 ft). Screen No.2 was dry during characterization sampling. Four rounds of groundwater characterization samples, collected from a perched zone and the regional aquifer from depths of 378.0 ft (screen No.1) and 915.0 ft (screen No.3), were chemically characterized for radionuclides, metals and trace elements, major ions, high-explosive (HE) compounds, total organic carbon, dissolved organic carbon, organic compounds, and stable isotopes (H, N, and O). Although well R-7 is primarily a characterization well, its design and construction also meet the requirements of a Resource Conservation and Recovery Act (RCRA)-compliant monitoring well as described in the US Environmental Protection Agency (EPA) document ''RCRA Groundwater Monitoring: Draft Technical Guidance,'' November 1992, EPA 530-R-93- 001. Incorporation of this well into a Laboratory-wide groundwater-monitoring program will be considered, and more specifically evaluated (e.g., sampling frequency, analytes, etc.), when the results of the well R-7 characterization activities are comprehensively evaluated in conjunction with other groundwater investigations in the ''Hydrogeologic Workplan'' (LANL 1998, 59599).

Geohydrologic study of the Michigan Basin for the applicability of Jack W. McIntyre`s patented process for simultaneous gas recovery and water disposal in production wells  

Science Conference Proceedings (OSTI)

Geraghty & Miller, Inc. of Midland, Texas conducted a geohydrologic study of the Michigan Basin to evaluate the applicability of Jack McIntyre`s patented process for gas recovery and water disposal in production wells. A review of available publications was conducted to identify, (1) natural gas reservoirs which generate large quantities of gas and water, and (2) underground injection zones for produced water. Research efforts were focused on unconventional natural gas formations. The Antrim Shale is a Devonian gas shale which produces gas and large quantities of water. Total 1992 production from 2,626 wells was 74,209,916 Mcf of gas and 25,795,334 bbl of water. The Middle Devonian Dundee Limestone is a major injection zone for produced water. ``Waterless completion`` wells have been completed in the Antrim Shale for gas recovery and in the Dundee Limestone for water disposal. Jack McIntyre`s patented process has potential application for the recovery of gas from the Antrim Shale and simultaneous injection of produced water into the Dundee Limestone.

Interpreting Horizontal Well Flow Profiles and Optimizing Well Performance by Downhole Temperature and Pressure Data  

E-Print Network (OSTI)

Horizontal well temperature and pressure distributions can be measured by production logging or downhole permanent sensors, such as fiber optic distributed temperature sensors (DTS). Correct interpretation of temperature and pressure data can be used to obtain downhole flow conditions, which is key information to control and optimize horizontal well production. However, the fluid flow in the reservoir is often multiphase and complex, which makes temperature and pressure interpretation very difficult. In addition, the continuous measurement provides transient temperature behavior which increases the complexity of the problem. To interpret these measured data correctly, a comprehensive model is required. In this study, an interpretation model is developed to predict flow profile of a horizontal well from downhole temperature and pressure measurement. The model consists of a wellbore model and a reservoir model. The reservoir model can handle transient, multiphase flow and it includes a flow model and a thermal model. The calculation of the reservoir flow model is based on the streamline simulation and the calculation of reservoir thermal model is based on the finite difference method. The reservoir thermal model includes thermal expansion and viscous dissipation heating which can reflect small temperature changes caused by pressure difference. We combine the reservoir model with a horizontal well flow and temperature model as the forward model. Based on this forward model, by making the forward calculated temperature and pressure match the observed data, we can inverse temperature and pressure data to downhole flow rate profiles. Two commonly used inversion methods, Levenberg- Marquardt method and Marcov chain Monte Carlo method, are discussed in the study. Field applications illustrate the feasibility of using this model to interpret the field measured data and assist production optimization. The reservoir model also reveals the relationship between temperature behavior and reservoir permeability characteristic. The measured temperature information can help us to characterize a reservoir when the reservoir modeling is done only with limited information. The transient temperature information can be used in horizontal well optimization by controlling the flow rate until favorite temperature distribution is achieved. With temperature feedback and inflow control valves (ICVs), we developed a procedure of using DTS data to optimize horizontal well performance. The synthetic examples show that this method is useful at a certain level of temperature resolution and data noise.

Well test analysis in fractured media  

DOE Green Energy (OSTI)

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

Proper centralizers can improve horizontal well cementing  

SciTech Connect

The selection and spacing of appropriate centralizers can improve the cementation of high-angle and horizontal wells. Mud removal is one of the most important factors in obtaining a good cement job. Effective centralization assists in mud removal and helps ensure an even cement coat around the casing. Centralizers for horizontal wells have to fulfill two requirements: They should have a high restoring capability and a low moving force, and they should allow pipe rotation and reciprocation. Conventional bow-type centralizers have been used successfully in some horizontal wells. But as the horizontal section length increases, special centralizers, such as low-moving-force, bow-type centralizers and rigid centralizers, may be necessary. The paper describes the following: cementing liners, centralization, torque and drag, centralizer placement, the bow-type centralizer, the rigid centralizer, and the downhole activated centralizer.

Subsurface steam sampling in Geysers wells  

DOE Green Energy (OSTI)

A new downhole sampling tool has been built for use in steam wells at The Geysers geothermal reservoir. The tool condenses specimens into an initially evacuated vessel that is opened down hole at the direction of an on-board computer. The tool makes a temperature log of the well as it is deployed, and the pressure and temperature of collected specimens are monitored for diagnostic purposes. Initial tests were encouraging, and the Department of Energy has funded an expanded effort that includes data gathering needed to develop a three-dimensional model of The Geysers geochemical environment. Collected data will be useful for understanding the origins of hydrogen chloride and non-condensable gases in the steam, as well as tracking the effect of injection on the composition of produced steam. Interested parties are invited to observe the work and to join the program.

Downhole Temperature Prediction for Drilling Geothermal Wells  

DOE Green Energy (OSTI)

Unusually high temperatures are encountered during drilling of a geothermal well. These temperatures affect every aspect of drilling, from drilling fluid properties to cement formulations. Clearly, good estimates of downhole temperatures during drilling would be helpful in preparing geothermal well completion designs, well drilling plans, drilling fluid requirements, and cement formulations. The thermal simulations in this report were conducted using GEOTEMP, a computer code developed under Sandia National Laboratories contract and available through Sandia. Input variables such as drilling fluid inlet temperatures and circulation rates, rates of penetration, and shut-in intervals were obtained from the Imperial Valley East Mesa Field and the Los Alamos Hot Dry Rock Project. The results of several thermal simulations are presented, with discussion of their impact on drilling fluids, cements, casing design, and drilling practices.

Monitoring well systems in geothermal areas  

DOE Green Energy (OSTI)

The ability to monitor the injection of spent geothermal fluids at reasonable cost might be greatly improved by use of multiple-completion techniques. Several such techniques, identified through contact with a broad range of experts from the groundwater and petroleum industries, are evaluated relative to application in the typical geologic and hydrologic conditions of the Basin and Range Province of the Western United States. Three basic monitor well designs are suggested for collection of pressure and temperature data: Single standpipe, multiple standpipe, and closed-system piezometers. A fourth design, monitor well/injection well dual completions, is determined to be inadvisable. Also, while it is recognized that water quality data is equally important, designs to allow water sampling greatly increase costs of construction, and so such designs are not included in this review. The single standpipe piezometer is recommended for use at depths less than 152 m (500 ft); several can be clustered in one area to provide information on vertical flow conditions. At depths greater than 152 m (500 ft), the multiple-completion standpipe and closed-system piezometers are likely to be more cost effective. Unique conditions at each monitor well site may necessitate consideration of the single standpipe piezometer even for deeper completions.

Investigation of the Effect of Non-Darcy Flow and Multi-Phase Flow on the Productivity of Hydraulically Fractured Gas Wells  

E-Print Network (OSTI)

Hydraulic fracturing has recently been the completion of choice for most tight gas bearing formations. It has proven successful to produce these formations in a commercial manner. However, some considerations have to be taken into account to design an optimum stimulation treatment that leads to the maximum possible productivity. These considerations include, but not limited to, non-Darcy flow and multiphase flow effects inside the fracture. These effects reduce the fracture conductivity significantly. Failing to account for that results in overestimating the deliverability of the well and, consequently, to designing a fracture treatment that is not optimum. In this work a thorough investigation of non-Darcy flow and multi-phase flow effects on the productivity of hydraulically fractured wells is conducted and an optimum fracture design is proposed for a tight gas formation in south Texas using the Unified Fracture Design (UFD) Technique to compensate for the mentioned effects by calculating the effective fracture permeability in an iterative way. Incorporating non-Darcy effects results in an optimum fracture that is shorter and wider than the fracture when only Darcy calculations are considered. That leads to a loss of production of 5, 18 percent due to dry and multiphase non-Darcy flow effects respectively. A comparison between the UFD and 3D simulators is also done to point out the differences in terms of methodology and results. Since UFD incorporated the maximum dimensionless productivity index in the fracture dimensions design, unlike 3D simulators, it can be concluded that using UFD to design the fracture treatment and then use the most important fracture parameters outputs (half length and CfDopt) as inputs in the simulators is a recommended approach.

Armored instrumentation cable for geothermal well logging  

DOE Green Energy (OSTI)

Multiconductor armored well-logging cable is used extensively by the oil and natural gas industry to lower various instruments used to measure the geological and geophysical parameters into deep wellbores. Advanced technology in oil-well drilling makes it possible to achieve borehole depths of 9 km (30,000 ft). The higher temperatures in these deeper boreholes demand advancements in the design and manufacturing of wireline cable and in the electrical insulating and armoring materials used as integral components. If geothermal energy is proved an abundant economic resource, drilling temperatures approaching and exceeding 300/sup 0/C will become commonplace. The adaptation of teflons as electrical insulating material permitted use of armored cable in geothermal wellbores where temperatures are slightly in excess of 200/sup 0/C, and where the concentrations of corrosive minerals and gases are high. Teflon materials presently used in wireline cables, however, are not capable of continuous operation at the anticipated higher temperatures.

Boise geothermal injection well: Final environmental assessment  

DOE Green Energy (OSTI)

The City of Boise, Idaho, an Idaho Municipal Corporation, is proposing to construct a well with which to inject spent geothermal water from its hot water heating system back into the geothermal aquifer. Because of a cooperative agreement between the City and the US Department of Energy to design and construct the proposed well, compliance to the National Environmental Policy Act (NEPA) is required. Therefore, this Environmental Assessment (EA) represents the analysis of the proposed project required under NEPA. The intent of this EA is to: (1) briefly describe historical uses of the Boise Geothermal Aquifer; (2) discuss the underlying reason for the proposed action; (3) describe alternatives considered, including the No Action Alternative and the Preferred Alternative; and (4) present potential environmental impacts of the proposed action and the analysis of those impacts as they apply to the respective alternatives.

Explosive stimulation of a geothermal well: GEOFRAC  

DOE Green Energy (OSTI)

This paper describes the first known explosive stimulation successfully conducted in a geothermal well. Two tests were performed in a 2690-meter-(8826-ft.) deep Union Oil well at the Geysers field in Northern California in December 1981. The heat-resistant process, called GEOFRAC, uses a new unique, explosive HITEX 2, which is a nondetonable solid at room temperature. Upon melting at a temperature of 177[degrees]C (350[degrees]F), the HITEX 2 liquid becomes an explosive that can be safely heated to temperatures greater than 260[degrees]C (500[degrees]F). These unique properties of the explosive were exploited in the GEOFRAC process through the cooperative efforts of Physics International Company (PI), Rocket Research Company (RRC), Union oil Company (UO), and the university of California Los Alamos National Laboratories (LANL).

Rotating preventers; Technology for better well control  

Science Conference Proceedings (OSTI)

This paper reports that recent changes in the oil and gas industry and ongoing developments in horizontal and underbalanced drilling necessitated development of a better rotating head. A new device called the rotating blowout preventer (RBOP) was developed by Seal-Tech. It is designed to replace the conventional rotating control head on top of BOP stacks and allows drilling operations to continue even on live (underbalanced) wells. Its low wear characteristics and high working pressure (1,500 psi) allow drilling rig crews to drill safely in slightly underbalanced conditions or handle severe well control problems during the time required to actuate other BOPs in the stack. Drilling with a RBOP allows wellbores to be completely closed in tat the drill floor rather than open as with conventional BOPs.

Pressure-activated well perforating apparatus  

Science Conference Proceedings (OSTI)

A well perforating technique utilizes a predetermined pressure difference developed at different points in the borehole to actuate the firing mechanism of a tubing conveyed perforating gun. A first embodiment incorporated as part of a well test string includes a packer for isolating a wellbore interval and a perforating gun connected in the string below the packer which is fired in response to development of a greater pressure in the annulus above the packer than in the isolated interval, thereby causing perforation at ''underbalanced'' conditions. A modified ''full-bore'' embodiment has an annular configuration firing mechanism as part of a tubing string and fires the perforating gun in response to development of a predetermined difference between the pressures at a point in the annulus and a point in the central bore of the tubing string.

Remote down-hole well telemetry  

DOE Patents (OSTI)

The present invention includes an apparatus and method for telemetry communication with oil-well monitoring and recording instruments located in the vicinity of the bottom of gas or oil recovery pipes. Such instruments are currently monitored using electrical cabling that is inserted into the pipes; cabling has a short life in this environment, and requires periodic replacement with the concomitant, costly shutdown of the well. Modulated reflectance, a wireless communication method that does not require signal transmission power from the telemetry package will provide a long-lived and reliable way to monitor down-hole conditions. Normal wireless technology is not practical since batteries and capacitors have to frequently be replaced or recharged, again with the well being removed from service. RF energy generated above ground can also be received, converted and stored down-hole without the use of wires, for actuating down-hole valves, as one example. Although modulated reflectance reduces or eliminates the loss of energy at the sensor package because energy is not consumed, during the transmission process, additional stored extra energy down-hole is needed.

TREATMENT OF HYDROCARBON, ORGANIC RESIDUE AND PRODUCTION CHEMICAL DAMAGE MECHANISMS THROUGH THE APPLICATION OF CARBON DIOXIDE IN NATURAL GAS STORAGE WELLS  

SciTech Connect

Two gas storage fields were studied for this project. Overisel field, operated by Consumer's Energy, is located near the town of Holland, Michigan. Huntsman Storage Unit, operated by Kinder Morgan, is located in Cheyenne County, Nebraska near the town of Sidney. Wells in both fields experienced declining performance over several years of their annual injection/production cycle. In both fields, the presence of hydrocarbons, organic materials or production chemicals was suspected as the cause of progressive formation damage leading to the performance decline. Core specimens and several material samples were collected from these two natural gas storage reservoirs. Laboratory studies were performed to characterize the samples that were believed to be representative of a reservoir damage mechanism previously identified as arising from the presence of hydrocarbons, organic residues or production chemicals. A series of laboratory experiments were performed to identify the sample materials, use these materials to damage the flow capacity of the core specimens and then attempt to remove or reduce the induced damage using either carbon dioxide or a mixture of carbon dioxide and other chemicals. Results of the experiments showed that pure carbon dioxide was effective in restoring flow capacity to the core specimens in several different settings. However, in settings involving asphaltines as the damage mechanism, both pure carbon dioxide and mixtures of carbon dioxide and other chemicals provided little effectiveness in damage removal.

These pressures include (1) uncertainty about crude oil prices that is forcing operators to reconsider some marginal ws/wo prospects; (2) demand for oil and gas in future periods; (3) effect of current rate of rig building; and (4) changing requirements of producers. This discussion evaluates the probable effects of possible changes in each of these areas.

Well servicing market report: Positive signs emerge  

Science Conference Proceedings (OSTI)

Domestic well servicing contractors head into 1988 with an improved outlook. But contractors will hasten to tell you this is not say they are now in a healthy industry with a strong demand for equipment and services. John Copeland, executive vice president of the Association of Oilwell Servicing Contractors (AOSC), says he sees encouragement mainly for two reasons: some producing companies have indicated a willingness to raise rig rates, and significant rig utilization gains were noted in the last quarter of 1987. For now, though, the big negatives are still haunting the industry. These are most often noted as inadequate prices for rigs and by far too many rigs chasing too few jobs.

Two-dimensional nonlinear finite element analysis of well damage due to reservoir compaction, well-to-well interactions, and localization on weak layers  

Science Conference Proceedings (OSTI)

In this paper the authors present the results of a coupled nonlinear finite element geomechanics model for reservoir compaction and well-to-well interactions for the high-porosity, low strength diatomite reservoirs of the Belridge field near Bakersfield, California. They show that well damage and failures can occur under the action of two distinct mechanisms: shear deformations induced by pore compaction, and subsidence, and shear deformations due to well-to-well interactions during production or water injection. They show such casting damage or failure can be localized to weak layers that slide or slip under shear due to subsidence. The magnitude of shear displacements and surface subsidence agree with field observations.

Modeling performance of horizontal, undulating, and multilateral wells  

E-Print Network (OSTI)

Horizontal, undulating, and multilateral wells are relatively new alternatives in field development because they can increase the productivity per well and reduce the cost of field development. Because the feasibility of these wells may not be valid in some reservoirs, well performance should be verified before making decisions. Undulation is usually associated to horizontal wells with some degrees. Existing inflow performance models do not account for the undulation of the well, which can cause significant error and economic loss. Moreover, some of the inflow models ignore pressure drop along the lateral, which is definitely not true in high production and long lateral wells. The inflow performance models of horizontal, undulating, and multilateral wells are developed in this study. The models can be divided into two main categories: the closed form model and the line source model. The closed form model applies for relatively low vertical permeability formations for the single-phase system and twophase system. The model is flexible and easy to apply with reasonable accuracy. The line source model does not have any restrictions with permeability. The model applies for single-phase system. The model is very accurate and easy to use. Both models can be applied to various well trajectories with realizable accuracy. As a result of this study, the well performance of unconventional well trajectories can be predicted and optimized.

Phase II of the Long Valley Exploratory Well was completed to a depth of 7588 feet in November 1991. The drilling comprised two sub-phases: (1) drilling 17-1/2 inch hole from the Phase I casing shoe at 2558 feet to a depth of 7130 feet, plugging back to 6826 feet, and setting 13-3/8 inch casing at 6825 feet, all during August--September 1991; and (2) returning in November to drill a 3.85-inch core hole deviated out of the previous wellbore at 6868 feet and extending to 7588 feet. Ultimate depth of the well is planned to be 20,000 feet, or at a bottomhole temperature of 500{degrees}C, whichever comes first. Total cost of this drilling phase was approximately $2.3 million, and funding was shared about equally between the California Energy Commission and the Department of Energy. Phase II scientific work will commence in July 1992 and will be supported by DOE Office of Basic Energy Sciences, DOE Geothermal Division, and other funding sources.

Evaluation of a geothermal well logging, DST and Pit test  

DOE Green Energy (OSTI)

This paper briefly discusses logging and testing operations and certain related physical aspects in geothermal well evaluations. A good understanding of thermal and hydrological characteristics of geothermal reservoirs are essential in geothermal well evaluations. Within geothermal reservoirs, in evaluating the wells, the two most important parameters that first could be estimated, then measured or calculated, are temperature and productivity. Well logs and wireline surveys are means of measuring formation temperatures. Drill Stem Tests (DST's) or Pit Tests are means of determining formation productivity. Geochemistry and Petrology are currently accepted as two evaluation yardsticks in geothermal well evaluations. investigations of cuttings and cores during drilling operations, along with studies on formation waters could be used in a predictive nature for temperature and productivity and could yield useful information on the resource.

Hydrologic Tests at Characterization Well R-14  

Science Conference Proceedings (OSTI)

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

Natural Gas Prices: Well Above Recent Averages  

Gasoline and Diesel Fuel Update (EIA)

5 5 Notes: The recent surge in spot prices at the Henry Hub are well above a typical range for 1998-1999 (in this context, defined as the average, +/- 2 standard deviations). Past price surges have been of short duration. The possibility of a downward price adjustment before the end of next winter is a source of considerable risk for storage operators who acquire gas at recent elevated prices. Storage levels in the Lower 48 States were 7.5 percent below the 5-year average (1995-1999) by mid-August (August 11), although the differential is only 6.4 percent in the East, which depends most heavily on storage to meet peak demand. Low storage levels are attributable, at least in part, to poor price incentives: high current prices combined with only small price

Horizontal wells in the Java Sea  

SciTech Connect

The utilization of the Navigation Drilling System in recent drilling activity has established that: Continuous build rates as high as 6.75 degrees/100 ft are achievable (with a .74 degree DTU), making possible the tapping of near platform reserves. The system provides the flexibility necessary to drill a continuous curve or an irregular path without bottomhole assembly changes. The system provides the flexibility for sidetracks to the ''low side'' of the well bore without coming out of the hole for bottomhole assembly changes or a cement plug. Geological objectives can be reached with a high degree of accuracy. The system greatly reduces the costly learning curve associated with rotary bottomhole assemblies and substantially increases the confidence of the operator. Significant drilling cost reductions resulted from the use of the system. The cost per foot was further reduced as additional familiarity with the equipment was gained.

Well-developed deformation in 42Si  

E-Print Network (OSTI)

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

Controlling annular gas flow in deep wells  

SciTech Connect

This article reports on the phenomenon of annular gas channeling. It can occur during primary cementing in wells with formations containing gas. Such channeling may lead to interzonal communication down hole, or even gas migration to the surface. Formation gas is normally contained by the cement slurry's hydrostatic pressure. Annular gas channeling usually results from volumetric changes associated with: cement hydration and fluid loss, poor cement placement techniques, high cement free water, cementing gelling properties, and excessive thickening times. Initially, the cement slurry acts as a true fluid, transmitting hydrostatic pressure to the formation gas and preventing its flow into the cement matrix. However, as the cement begins to set, changing from a fluid state to a rigid state, it gradually begins to lose its ability to transmit hydrostatic pressure. This period of change is usually referred to as the ''transition period.'' Shrinkage of the cement volume compounds the problem and eventually can lead to poor binding between the cement and formation, thereby allowing gas to flow through gaps at the formation-cement interface.

Technology for Increasing Geothermal Energy Productivity. Computer Models to Characterize the Chemical Interactions of Goethermal Fluids and Injectates with Reservoir Rocks, Wells, Surface Equiptment  

DOE Green Energy (OSTI)

This final report describes the results of a research program we carried out over a five-year (3/1999-9/2004) period with funding from a Department of Energy geothermal FDP grant (DE-FG07-99ID13745) and from other agencies. The goal of research projects in this program were to develop modeling technologies that can increase the understanding of geothermal reservoir chemistry and chemistry-related energy production processes. The ability of computer models to handle many chemical variables and complex interactions makes them an essential tool for building a fundamental understanding of a wide variety of complex geothermal resource and production chemistry. With careful choice of methodology and parameterization, research objectives were to show that chemical models can correctly simulate behavior for the ranges of fluid compositions, formation minerals, temperature and pressure associated with present and near future geothermal systems as well as for the very high PT chemistry of deep resources that is intractable with traditional experimental methods. Our research results successfully met these objectives. We demonstrated that advances in physical chemistry theory can be used to accurately describe the thermodynamics of solid-liquid-gas systems via their free energies for wide ranges of composition (X), temperature and pressure. Eight articles on this work were published in peer-reviewed journals and in conference proceedings. Four are in preparation. Our work has been presented at many workshops and conferences. We also considerably improved our interactive web site (geotherm.ucsd.edu), which was in preliminary form prior to the grant. This site, which includes several model codes treating different XPT conditions, is an effective means to transfer our technologies and is used by the geothermal community and other researchers worldwide. Our models have wide application to many energy related and other important problems (e.g., scaling prediction in petroleum production systems, stripping towers for mineral production processes, nuclear waste storage, CO2 sequestration strategies, global warming). Although funding decreases cut short completion of several research activities, we made significant progress on these abbreviated projects.

Pleasant Bayou location was inactive from 1983 until the cleanout of the production and disposal wells in 1986. The surface facilities were rehabilitated and after shakedown of the system, additional repair of wellhead valves, and injection of an inhibitor pill, continuous long-term production was started in 1988. Over two years of production subsequent to that are reviewed here, including: production data, brine sampling and analysis, hydrocarbon sampling and analysis, solids sampling and analysis, scale control and corrosion monitoring and control.

Application of horizontal wells in steeply dipping reservoirs  

E-Print Network (OSTI)

A three-dimensional reservoir simulation study is performed to evaluate the impact of horizontal well applications on oil recovery from steeply dipping reservoirs. The Provincia field, located in Colombia, provided the basic reservoir information for the study. Reservoir simulation results indicate that for reservoir dip angles greater than about 40', this parameter has little or no effect on the primary recovery performance for homogeneous high-permeability reservoirs, The initial gascap size and the anisotropy of permeability (kv/kh ratio) are the dominant parameters affecting the oil recovery. For thin reservoirs, the location of the horizontal injector will not significantly affect the oil recovery. Simultaneous gas and water injection through horizontal wells can increase the oil recovery factor from almost 35% under primary production to 40%. A significant incremental oil recovery could be expected by employing horizontal wells for simultaneous gas and water injection. A comparison of the production performance of horizontal and vertical producers shows that a horizontal well can produce oil up to 2.5 times the oil rate of a vertical well, without a high rate of gas production. Also, the use of horizontal producers significantly accelerates the oil recovery. For the case of a homogeneous reservoir under simultaneous gas and water injection, the horizontal well system does not give a significant increment in the oil recovery compared to the vertical well system.

Monitor well responses at the Raft River, Idaho, Geothermal Site  

DOE Green Energy (OSTI)

Effects of geothermal fluid production and injection on overlying ground-water aquifers have been studied at the Raft River Geothermal Site in southcentral Idaho. Data collected from 13 monitor wells indicate a complex fractured and porous media controlled ground-water flow system affected by natural recharge and discharge, irrigation withdrawal, and geothermal withdrawal and injection. The monitor wells are completed in aquifers and aquitards overlying the principal geothermal aquifers. Potentiometric heads and water quality are significantly affected by natural upward geothermal leakage via faults and matrix seepage. No significant change in water quality data has been observed, but potentiometric head changes resulted due to geothermal resource testing and utilization. Long-term hydrographs for the wells exhibit three distinct patterns, with superimposed responses due to geothermal pumping and injection. Well hydrographs typical of the Shallow aquifer exhibit effects of natural recharge and irrigation withdrawals. For selected wells, pressure declines due to injection and pressure buildup associated with pumping are observed. The latter effect is presumably due to the elastic deformation of geologic material overlying the stressed aquifers. A second distinct pattern occurs in two wells believed to be hydraulically connected to the underlying Intermediate aquifer via faults. These wells exhibit marked buildup effects due to injection as well as responses typical of the Shallow aquifer. The third pattern is demonstrated by three monitor wells near the principal production wells. This group of wells exhibits no seasonal potentiometric head fluctuations. Fluctuations which do occur are due to injection and pumpage. The three distinct hydrograph patterns are composites of the potentiometric head responses occurring in the various aquifers underlying the Raft River Site.
