The investigation of fracture aperture effect on shale gas transport using discrete fracture model  

Science Journals Connector (OSTI)

Abstract Discrete fracture model (DFM) numerical simulation is used to investigate the shale gas transports in fractured porous media in this paper. A new seepage flow mathematic model, in which flow in fracture meets “Cubic law” and matrix meets “non-Darcy law”, is adopted and fracture aperture effect on the transport behavior is simulated by solving the nonlinear partial differential equations using finite element analysis (FEA). In this DFM, fluid flows into wellbore which is surrounded by impermeable rock matrix is merely through fractures that connect to it. The model is used to simulate a random generated fractures network to study the flow and transport characteristics in fractured porous media (FPM). Several cases with different fracture aperture in same natural fractured model are given. The preliminary simulation results show that both the natural and hydraulic fracture aperture have a significant impact on shale gas migration and production.

Dependence of gas shale fracture permeability on effective stress and reservoir pressure: Model match and insights  

Science Journals Connector (OSTI)

Abstract Although permeability data for different gas shales have been reported previously and attempts have been made to match permeability with empirical correlations, theoretical studies of shale permeability modelling are lacking. In this work, the correlation between fracture permeability and effective stress is established for gas shales through theoretical derivation. This model is able to match the permeability data for different gas shales. The matching results for the gas shale studied show that the model coefficient, fracture compressibility, which decreases as initial shale permeability increases, is strongly affected by the flow directions and varies with the shale’s mineralogical composition. Furthermore, the correlation between fracture permeability and reservoir pressure has also been established. Sensitivity study shows that fracture permeability may decrease significantly with the reservoir pressure drawdown. Moreover, the horizontal fracture permeability drop is found to be significantly affected by the Young’s modulus’ anisotropic ratio (Eh/Ev). The insights gained warrant further theoretical and experimental studies to evaluate shale fracture permeability.

Fractured gas reservoirs in the Devonian shale of the Illinois and Appalachian basins  

SciTech Connect (OSTI)

The Devonian and Lower Mississippian black shale sequence of Kentucky includes the New Albany Shale of Illinois basin and the Ohio Shale of the Appalachian basin. Fractured reservoirs in the Ohio Shale contain a major gas resource, but have not been so prolific in the New Albany Shale. The authors propose two models of fractured shale reservoirs in both the Illinois and the Appalachian basins, to be tested with gas production data. (1) Where reactivated basement faults have propagated to the surface, the lack of an effective seal has prevented the development of overpressure. The resulting fracture system is entirely tectonic is origin, and served mainly as a conduit for gas migration from the basin to the surface. Gas accumulations in such reservoirs typically are small and underpressured. (2) Where basement faults have been reactivated but have not reached the surface, a seal on the fractured reservoir is preserved. In areas where thermal maturity has been adequate, overpressuring due to gas generation resulted in a major extension of the fracture system, as well as enhanced gas compression and adsorption. Such gas accumulations are relatively large. Original overpressuring has been largely lost, due both to natural depletion and to uncontrolled production. The relative thermal immaturity of the Illinois basin accounts for the scarcity of the second type of fractured reservoir and the small magnitude of the New Albany Shale gas resource.

The impact of diffusion type on multiscale discrete fracture model numerical simulation for shale gas  

Science Journals Connector (OSTI)

Abstract The development of unconventional gas reservoirs represents totally distinctive characteristics as compared with the conventional reservoirs. The complex pore structure in shale reservoir determines its special flow mechanism, which can be divided into several categories according to the size and type of pores- non Darcy flow, gas slippage, adsorption-desorption and gas diffusion effect. Based on the gas molecules diffusion form in porous media and combining with the multi-scale distribution structural characteristics of shale gas reservoirs, the shale gas diffusion mechanisms in the shale reservoir space including the diffusion of dissolved gases in the organic kerogen and the diffusion of free gas in the nanopores are analyzed in this paper. Meanwhile, the diffusion in the nanopores consists of Knudsen diffusion (KN ? 10), Fick diffusion (KN ? 0.1) and transition diffusion (0.1 shale gas flow in matrix and fracture networks, and also for their mass transfer in between without neglecting its varying-scale nature following the concept of discrete fracture network (DFN). In addition, we also investigate the different diffusion mechanisms' influences on the production and pressure in the tight shale gas reservoir. Ultimately, concluding that the gas diffusion mechanisms in micro-and nano-scale matrix block have a greater impact on the distribution of shale gas production (especially the production at early time) and reservoir pressure.

Evaluation of naturally fractured gas shale production utilizing multiwell transient tests: A field study  

SciTech Connect (OSTI)

A series of multiple well transient tests were conducted in a Devonian shale gas field in Meigs County, Ohio. Production parameters were quantified and it was determined that the reservoir is highly anisotropic, which is a significant factor in calculating half-fracture length from pressure transient data. Three stimulation treatments, including conventional explosive shooting, nitrogen foam frac, and high energy gas frac (HEGF), were compared on the basis of overall effectiveness and performance. Based on the evaluation of results, the nitrogen foam frac provided the most improved productivity. The study provided new type curves and analytical solutions for the mathematical representation of naturally fractured reservoirs and confirmed that the shale reservoir in Meigs County can be modeled as a dual porosity system using pseudosteady-state gas transfer from the matrix to the fracture system.

Processing dipole acoustic logging data to image fracture network in shale gas reservoirs  

Science Journals Connector (OSTI)

A recent advance in borehole remote acoustic reflection imaging is the utilization of a dipole acoustic system in a borehole to emit and receive elastic waves to and from a remote geologic reflector in formation. An important application of this new technique is the delineation of fracture network in shale gas reservoirs as interest and activities in shale gas exploration increase in China. We develop a data processing procedure and implement it to handle routine processing of dipole acoustic logging data. The procedure takes into account the characteristics of the dipole data such as frequency dispersion attenuation recording length and dipole source orientation etc. to obtain an image of reflectors within 20~30 meters around the borehole. We have applied the technique to process dipole acoustic data from several wells drilled into gas reservoirs in China. The obtained images clearly identify major fracture network in the gas producing intervals of the reservoir demonstrating the effectiveness of the imaging technique.

Gas sales starting from Indiana`s fractured New Albany shale  

SciTech Connect (OSTI)

The Indiana Department of Natural Resources, Division of Oil and Gas issued 138 drilling permits from Dec. 1, 1994, through July 31, 1996, in 17 counties in a growing play for gas in Devonian New Albany shale in southern Indiana. The permits are active in the form of locations, drilling wells, wells in the completion process, and wells producing gas in the dewatering stage. Geologically in southwestern Indiana the New Albany shale exploration play is found in three provinces. These are the Wabash platform, the Terre Haute reef bank, and the Vincennes basin. Exploration permits issued on each of these geologic provinces are as follows: Wabash platform 103, Terra Haute reef bank 33, and Vincennes basin two. The authors feel that the quantity and effectiveness of communication of fracturing in the shale will control gas production and water production. A rule of thumb in a desorption reservoir is that the more water a shale well makes in the beginning the more gas it will make when dewatered.

Microbial communities in flowback water impoundments from hydraulic fracturing for recovery of shale gas  

SciTech Connect (OSTI)

Hydraulic fracturing for natural gas extraction from shale produces waste brine known as flowback that is impounded at the surface prior to reuse and/or disposal. During impoundment, microbial activity can alter the fate of metals including radionuclides, give rise to odorous compounds, and result in biocorrosion that complicates water and waste management and increases production costs. Here, we describe the microbial ecology at multiple depths of three flowback impoundments from the Marcellus shale that were managed differently. 16S rRNA gene clone libraries revealed that bacterial communities in the untreated and biocide-amended impoundments were depth dependent, diverse, and most similar to species within the taxa [gamma]-proteobacteria, [alpha]-proteobacteria, ?-proteobacteria, Clostridia, Synergistetes, Thermotogae, Spirochetes, and Bacteroidetes. The bacterial community in the pretreated and aerated impoundment was uniform with depth, less diverse, and most similar to known iodide-oxidizing bacteria in the [alpha]-proteobacteria. Archaea were identified only in the untreated and biocide-amended impoundments and were affiliated to the Methanomicrobia class. This is the first study of microbial communities in flowback water impoundments from hydraulic fracturing. The findings expand our knowledge of microbial diversity of an emergent and unexplored environment and may guide the management of flowback impoundments.

Well testing model for multi-fractured horizontal well for shale gas reservoirs with consideration of dual diffusion in matrix  

Science Journals Connector (OSTI)

Abstract Shale gas reservoir is typical unconventional reservoir, it's necessary to take advantage of multi-stage fractured horizontal well so as to develop those kinds of reservoirs, which can form high conductivity hydraulic fractures and activate natural fractures. Due to the existence of concentration gap between matrix and fractures, desorption gas can simultaneously diffuse into the natural fractures and hydraulic fractures. This process can be called dual diffusion. Based on the triple-porosity cubic model, this paper establishes a new well testing model of multi-stage fractured horizontal well in shale gas reservoir with consideration of the unique mechanisms of desorption and dual diffusion in matrix. Laplace transformation is employed to solve this new model. The pseudo pressure transient responses are inverted into real time space with stehfest numerical inversion algorithm. Type curves are plotted, and different flow regimes in shale gas reservoirs are identified and the effects of relevant parameters are analyzed as well. Considering the mechanism of dual diffusion in matrix, the flow can be divided into five regimes: early linear flow; pseudo-steady state inter-porosity flow; the diffusion from matrix into micro-fractures; the diffusion from matrix into hydraulic fractures and boundary-dominated flow. There are large distinctions of pressure response between pseudo steady state diffusion and unsteady state diffusion under different value of pore volume ratio. It's similar to the feature of pseudo-steady state inter-porosity flow, diffusion coefficient and Langmuir parameters reflect the characters of pseudo-steady state diffusion. The numbers of stage of hydraulic fractures have certain impact on the shape factor of matrix and the inter-porosity coefficient. This new model is validated compared with some existing models. Finally, coupled with an application, this mew model can be approximately reliable and make some more precise productivity prediction.

Two-phase pressure transient analysis for multi-stage fractured horizontal well in shale gas reservoirs  

Science Journals Connector (OSTI)

Abstract Most researches on shale gas production and pressure transient analysis placed more emphasis on single-phase flow, the two-phase flow caused by flowback after hydrofracture in shale gas reservoirs does not attract much attention. This paper presents a two-phase pressure transient analysis model of multi-stage fractured horizontal well with the consideration of wellbore storage, skin effect, two-phase saturation, hydraulic fractures parameters and desorption characteristics of shale gas reservoirs. Accurate solution to this flow model is obtained by the use of source function theory, Laplace transform, three-dimensional eigenvalue method and orthogonal transformation. Pseudo-pressure and pseudo-pressure derivative type curve is plotted by using the Stehfest algorithm. Seven different flow regimes have been identified and the effects of influence factors such as initial saturation, skin factor, absorption index, fracture stages, horizontal well lateral length and wellbore storage coefficient have also been discussed. The presents research could be used to interpret the pressure behavior more accurately and effectively of shale gas reservoirs.

Hydraulic fracturing and associated stress modeling for the Eastern Gas Shales Project. Final report  

SciTech Connect (OSTI)

Frac fluid flow, structure, and fracture mechanics simulations are developed for predicting and optimizing fracture dimensions and fluid leak-offs. Roles of in situ stress and material properties for possible vertical migration of fractures from the pay zone are discussed. Rationale for foam and dendritic fracturing experiments is presented along with numerical experiments for examining the phenomena of spalling of the fracture faces and conditions for secondary fracture initiation. Assignment of conventional, foam, cyrogenic, dendritic, and explosive fracturing treatments for specific reservoir properties is considered. Variables include fracture density and extent, shale thickness, in-situ stress gradients, energy assist mechanisms, well clean-up, shale-frac fluid interaction, proppant selection, and fracture height control. The analysis suggests that correlation with prevailing in situ stress gradients are promising diagnostic indicators for fracture treatment selection and design. In conclusion, the comprehensive development of an economical strategy requires extensive and controlled field testing with supporting predictive analyses of reservoir responses. Finite element modeling of reservoir in situ stress trajectories and the flow and fracture responses in the reservoir is recommended.

What is shale gas and why is it important?  

Reports and Publications (EIA)

Shale gas refers to natural gas that is trapped within shale formations. Shales are fine-grained sedimentary rocks that can be rich sources of petroleum and natural gas. Over the past decade, the combination of horizontal drilling and hydraulic fracturing has allowed access to large volumes of shale gas that were previously uneconomical to produce. The production of natural gas from shale formations has rejuvenated the natural gas industry in the United States.

Gas Research Institute improved fracturing. Unconventional natural gas program, eastern devonian shales diagnostic program: Black No. 1 well experiment results. Third quarterly report, October 1979-December 1979  

SciTech Connect (OSTI)

During the last quarter of 1979, Sandia National Laboratories participated in an experiment with Thurlow Weed and Associates and the Morgantown Energy Technology Center. This Devonian Shale gas stimulation experiment was conducted in an area north of Columbus, Ohio. One purpose of the experiment was to apply the diagnostic instrumentation that is available for fracture mapping and characterization to increase our understanding of the stimulation technique. The induced fracture apparently followed a pre-existing fracture vertically from the borehole with an orientation of the N 62/sup 0/ E and in the latter stages of the stimulation turned into a shallower horizontal fracture. This fracture behavior was confirmed by several diagnostic analyses and demonstrates the insight that can be gained by fully instrumented stimulation experiments.

Microbial Community Changes in Hydraulic Fracturing Fluids and Produced Water from Shale Gas Extraction  

SciTech Connect (OSTI)

Microbial communities associated with produced water from hydraulic fracturing are not well understood, and their deleterious activity can lead to significant increases in production costs and adverse environmental impacts. In this study, we compared the microbial ecology in prefracturing fluids (fracturing source water and fracturing fluid) and produced water at multiple time points from a natural gas well in southwestern Pennsylvania using 16S rRNA gene-based clone libraries, pyrosequencing, and quantitative PCR. The majority of the bacterial community in prefracturing fluids constituted aerobic species affiliated with the class Alphaproteobacteria. However, their relative abundance decreased in produced water with an increase in halotolerant, anaerobic/facultative anaerobic species affiliated with the classes Clostridia, Bacilli, Gammaproteobacteria, Epsilonproteobacteria, Bacteroidia, and Fusobacteria. Produced water collected at the last time point (day 187) consisted almost entirely of sequences similar to Clostridia and showed a decrease in bacterial abundance by 3 orders of magnitude compared to the prefracturing fluids and produced water samplesfrom earlier time points. Geochemical analysis showed that produced water contained higher concentrations of salts and total radioactivity compared to prefracturing fluids. This study provides evidence of long-term subsurface selection of the microbial community introduced through hydraulic fracturing, which may include significant implications for disinfection as well as reuse of produced water in future fracturing operations.

Technically recoverable Devonian shale gas in Kentucky  

SciTech Connect (OSTI)

This report evaluates the natural gas potential of the Devonian Age shales of Kentucky. For this, the study: (1) compiles the latest geologic and reservoir data to establish the gas in-place; (2) analyzes and models the dominant gas production mechanisms; and (3) examines alternative well stimulation and production strategies for most efficiently recovering the in-place gas. The major findings of the study include the following: (1) The technically recoverable gas from Devonian shale (Lower and Upper Huron, Rhinestreet, and Cleveland intervals) in Kentucky is estimated to range from 9 to 23 trillion cubic feet (Tcf). (2) The gas in-place for the Devonian shales in eastern Kentucky is 82 Tcf. About one half of this amount is found in the Big Sandy gas field and its immediate extensions. The remainder is located in the less naturally fractured, but organically rich area to the west of the Big Sandy. (3) The highly fractured shales in the Big Sandy area in southeast Kentucky and the more shallow shales of eastern Kentucky respond well to small-scale stimulation. New, larger-scale stimulation technology will be required for the less fractured, anisotropic Devonian shales in the rest of the state. 44 refs., 49 figs., 24 tabs.

NATURAL GAS FROM SHALE: Questions and Answers  

Broader source: Energy.gov (indexed) [DOE]

Representation of common equipment at a natural gas hydraulic fracturing drill pad. Representation of common equipment at a natural gas hydraulic fracturing drill pad. How is Shale Gas Produced? Shale gas formations are "unconventional" reservoirs - i.e., reservoirs of low "permeability." Permeability refers to the capacity of a porous, sediment, soil - or rock in this case - to transmit a fluid. This contrasts with a "conventional" gas reservoir produced from sands and carbonates (such as limestone). The bottom line is that in a conventional reservoir, the gas is in interconnected pore spaces, much like a kitchen sponge, that allow easier flow to a well; but in an unconventional reservoir, like shale, the reservoir must be mechanically "stimulated" to

Conceptual study of thermal stimulation in shale gas formations  

Science Journals Connector (OSTI)

Abstract Shale gas formations have become a major source of energy in recent years. Developments in hydraulic fracturing technology have made these reservoirs more accessible and productive. Apart from other dissimilarities from conventional gas reservoirs, one major difference is that a considerable amount of gas produced from these shale gas formations comes from desorption. Up to 85% of the total gas within shale can be found as an adsorbed phase on clay and kerogen, so how much adsorbed gas can be produced will have significant impact on ultimate gas recovery. The Langmuir isotherm has been widely used in industry to describe the pressure dependence of adsorbed gas. However, temperature dependent adsorption behavior and its major implications for evaluating thermal stimulation as a recovery method for shale reservoirs have not been thoroughly explored. Therefore, in order to design and analyze the thermal treatment of shale gas formations successfully, it is crucial to understand the effects of fracture heating on the shale gas adsorption and desorption phenomenon, and how can we exploit such effects to enhance shale gas recovery from hydraulically fractured reservoirs. Even though numerous research efforts have been focused on thermal recovery of shale oil, its possible application to shale gas has not been investigated. In this research, we propose a method to evaluate desorbed gas as a function of pressure and temperature in shale formations, by regression of a Bi-Langmuir model on Langmuir isotherm data. We have developed a fully coupled unconventional reservoir simulator, which is capable of capturing real gas flow in the shale matrix and in the hydraulic fracture by accounting for the effects of gas desorption and diffusion, as well as the temperature diffusion process within the matrix. This simulator enables us to investigate the effects of fracture heating on the shale gas desorption phenomenon on the global well performance and recovery. The results of this study show, for the first time in a rigorous way, that by increasing the temperature within the fracture, shale gas recovery can be improved. We have rationalized and quantified relations between the adsorption/desorption fundamental phenomena and stimulation temperature, fracture spacing, reservoir permeability and bottom hole pressure. The thermal properties of shale formations only have limited impacts on long term production. The results of this study can provide a guidance to develop a strategy to design thermal treatment in hydraulically fractured shale formations and propose the degree of thermal stimulation temperature required in a fracture to promote an economically viable return on production.

Simulation study on the CO2-driven enhanced gas recovery with sequestration versus the re-fracturing treatment of horizontal wells in the U.S. unconventional shale reservoirs  

Science Journals Connector (OSTI)

Abstract It is proposed that very low permeability formations are possible candidates for CO2 sequestration. Further, experimental studies have shown that shale formations have huge affinity to adsorb CO2, the order of 5 to 1 compared to the methane. Therefore, potential sequestration of CO2 in shale formations leading to enhanced gas recovery (EGR) will be a promising while challenging target for the oil and gas industry. On the other side, hydraulic re-fracturing treatment of shale gas wells is currently gaining more attention due to the poor performance of shale gas reservoirs after a couple years of production. Hence, investigating and comparing the performance of CO2-EGR with the re-fracturing treatment is essential for the future economic viability of depleted shale gas reservoirs. This paper presents a systematic comparison of the effect of these two processes on improving gas production performance of unconventional reservoirs, which is not well understood and has not been studied thoroughly in the literature. In this paper, a shale gas field data has been evaluated and incorporated in our simulations for both CO2-EGR and re-fracturing treatment purposes. Numerical simulations are performed using local grid refinement (LGR) in order to accurately model the non-linear pressure drop. Also, a dual-porosity/dual-permeability model is incorporated in the reservoir simulation model. Further, the uncertainties associated with inter-related set of geologic and engineering parameters are evaluated and quantified for re-fracturing treatment through several simulation runs. This comprehensive sensitivity study helps in understanding the key reservoir and fracture properties that affect the production performance and enhanced gas recovery in shale gas reservoirs. The results showed that re-fracturing treatment outperforms CO2-EGR due to the pronounced effect on cumulative methane gas production. Moreover, the sensitivity analysis showed that the characteristics of reservoir matrix including permeability and porosity are the most influential parameters for re-fracturing treatment. The findings of this study recommend hydraulic re-fracturing of shale reservoirs at first for enhancing gas production followed by CO2 injection at a later time. This work provides field operators with more insight into maximizing gas recovery from unconventional shale gas reservoirs using re-fracturing stimulation, CO2 injection, or a combination of both methods.

Water management practices used by Fayetteville shale gas producers.  

SciTech Connect (OSTI)

Water issues continue to play an important role in producing natural gas from shale formations. This report examines water issues relating to shale gas production in the Fayetteville Shale. In particular, the report focuses on how gas producers obtain water supplies used for drilling and hydraulically fracturing wells, how that water is transported to the well sites and stored, and how the wastewater from the wells (flowback and produced water) is managed. Last year, Argonne National Laboratory made a similar evaluation of water issues in the Marcellus Shale (Veil 2010). Gas production in the Marcellus Shale involves at least three states, many oil and gas operators, and multiple wastewater management options. Consequently, Veil (2010) provided extensive information on water. This current study is less complicated for several reasons: (1) gas production in the Fayetteville Shale is somewhat more mature and stable than production in the Marcellus Shale; (2) the Fayetteville Shale underlies a single state (Arkansas); (3) there are only a few gas producers that operate the large majority of the wells in the Fayetteville Shale; (4) much of the water management information relating to the Marcellus Shale also applies to the Fayetteville Shale, therefore, it can be referenced from Veil (2010) rather than being recreated here; and (5) the author has previously published a report on the Fayetteville Shale (Veil 2007) and has helped to develop an informational website on the Fayetteville Shale (Argonne and University of Arkansas 2008), both of these sources, which are relevant to the subject of this report, are cited as references.

Natural gas from shale formation – The evolution, evidences and challenges of shale gas revolution in United States  

Science Journals Connector (OSTI)

Abstract Extraction of natural gas from shale rock in the United States (US) is one of the landmark events in the 21st century. The combination of horizontal drilling and hydraulic fracturing can extract huge quantities of natural gas from impermeable shale formations, which were previously thought to be either impossible or uneconomic to produce. This review offers a comprehensive insight into US shale gas opportunities, appraising the evolution, evidence and the challenges of shale gas production in the US. The history of US shale gas in this article is divided into three periods and based on the change of oil price (i.e., the period before the 1970s oil crisis, the period from 1970s to 2000, and the period since 2000), the US has moved from being one of the world's biggest importers of gas to being self-sufficient in less than a decade, with the shale gas production increasing 12-fold (from 2000 to 2010). The US domestic natural gas price hit a 10-year low in 2012. The US domestic natural gas price in the first half of 2012 was about $2 per million British Thermal Unit (BTU), compared with Brent crude, the world benchmark price for oil, now about $ 80–100/barrel, or $14–17 per million BTU. Partly due to an increase in gas-fired power generation in response to low gas prices, US carbon emissions from fossil-fuel combustion fell by 430 million ton CO2 – more than any other country – between 2006 and 2011. Shale gas also stimulated economic growth, creating 600,000 new jobs in the US by 2010. However, the US shale gas revolution would be curbed, if the environmental risks posed by hydraulic fracturing are not managed effectively. The hydraulic fracturing is water intensive, and can cause pollution in the marine environment, with implications for long-term environmental sustainability in several ways. Also, large amounts of methane, a powerful greenhouse gas, can be emitted during the shale gas exploration and production. Hydraulic fracturing also may induce earthquakes. These environmental risks need to be managed by good practices which is not being applied by all the producers in all the locations. Enforcing stronger regulations are necessary to minimize risk to the environment and on human health. Robust regulatory oversight can however increase the cost of extraction, but stringent regulations can foster an historic opportunity to provide cheaper and cleaner gas to meet the consumer demand, as well as to usher in the future growth of the industry.

NATURAL GAS FROM SHALE: Questions and Answers  

Broader source: Energy.gov (indexed) [DOE]

is shale gas? is shale gas? Basically, it is natural gas - primarily methane - found in shale formations, some of which were formed 300-million-to-400-million years ago during the Devonian period of Earth's history. The shales were deposited as fine silt and clay particles at the bottom of relatively enclosed bodies of water. At roughly the same time, primitive plants were forming forests on land and the first amphibians were making an appearance. Some of the methane that formed from the organic matter buried with the sediments escaped into sandy rock layers adjacent to the shales, forming conventional accumulations of natural gas which are relatively easy to extract. But some of it remained locked in the tight, low permeability shale layers, becoming shale gas.

Numerical investigation of gas flow rate in shale gas reservoirs with nanoporous media  

Science Journals Connector (OSTI)

Abstract Theoretical analysis of transport mechanism of gas flow in shale gas reservoirs with nanoporous media was carried out on the basis of molecular kinetic theory. The motion equation and mathematical model of shale gas transport in multi-scale medium are established in this article. The pressure distribution equation of radial flow was derived, and the computing method of the control area of gas well was presented. Additionally, the volume flow rate equations of vertical and horizontal fractured wells were obtained. Through Newton iterative method, volume flow rate was analyzed, considering various factors such as production pressure drawdown, fracture half-length, fracture conductivity, fracture spacing and diffusion coefficient. According to the numerical results, the volume flow rate of the gas well increases when the diffusion coefficient grows. Consequently diffusion in shale gas reservoirs with nanoporous media plays an important role. With increase of fracture half-length, the volume flow rate increases first and then tends towards stability. Moreover, for certain length of the horizontal wellbore, when fracture spacing increases and the number of the fractures lessens, the control area and the volume flow rate of the gas well decreases. Therefore, there is an optimum allocation among these factors to achieve maximum volume flow.

NATURAL GAS FROM SHALE: Questions and Answers Why is Shale Gas Important?  

Broader source: Energy.gov (indexed) [DOE]

Why is Shale Gas Important? Why is Shale Gas Important? With the advance of extraction technology, shale gas production has led to a new abundance of natural gas supply in the United States over the past decade, and is expected to continue to do so for the foreseeable future. According to the Energy Information Administration (EIA), the unproved technically recoverable U.S. shale gas resource is estimated at 482 trillion cubic feet. 1 Estimated proved and unproved shale gas resources amount to a combined 542 trillion cubic feet (or 25 percent) out of a total U.S. resource of 2,203 trillion cubic feet. 2 U.S. shale gas production has increased 12-fold over the last

Devonian shale gas resource assessment, Illinois basin  

SciTech Connect (OSTI)

In 1980 the National Petroleum Council published a resource appraisal for Devonian shales in the Appalachian, Michigan, and Illinois basins. Their Illinois basin estimate of 86 TCFG in-place has been widely cited but never verified nor revised. The NPC estimate was based on extremely limited canister off-gas data, used a highly simplified volumetric computation, and is not useful for targeting specific areas for gas exploration. In 1994 we collected, digitized, and normalized 187 representative gamma ray-bulk density logs through the New Albany across the entire basin. Formulas were derived from core analyses and methane adsorption isotherms to estimate total organic carbon (r{sup 2}=0.95) and gas content (r{sup 2}=0.79-0.91) from shale bulk density. Total gas in place was then calculated foot-by-foot through each well, assuming normal hydrostatic pressures and assuming the shale is gas saturated at reservoir conditions. The values thus determined are similar to peak gas contents determined by canister off-gassing of fresh cores but are substantially greater than average off-gas values. Greatest error in the methodology is at low reservoir pressures (or at shallow depths), however, the shale is generally thinner in these areas so the impact on the total resource estimate is small. The total New Albany gas in place was determined by integration to be 323 TCFG. Of this, 210 TCF (67%) is in the upper black Grassy Creek Shale, 72 TCF (23%) in the middle black and gray Selmier Shale, and 31 TCF (10%) in the basal black Blocher Shale. Water production concerns suggest that only the Grassy Creek Shale is likely to be commercially exploitable.

Gas potential of new Albany shale (Devonian-Mississippian) in the Illinois Basin  

SciTech Connect (OSTI)

A study to update and evaluate publicly available data relating to present and potential gas production from New Albany Shale in the Illinois basin was conducted cooperatively by the Indiana. Illinois, and Kentucky geological surveys (Illinois Basin Consortium), and was partially funded by the Gas Research Institute. Deliverables included a plate of stratigraphic cross sections and six basin-wide maps at a scale of 1:1,000,000. The New Albany Shale is an organic-rich brownish black shale present throughout the Illinois basin. Gas potential of the New Albany Shale may be great because it contains an estimated 86 tcf of natural gas and has produced modest volumes since 1858 from more than 60 fields, mostly in the southeastern part of the basin. Reservoir beds include organic-rich shales of the Grassy Creek (Shale), Clegg Creek, and Blocher (Shale) members. Limited geologic and carbon isotope data indicate that the gas is indigenous and thermogenic. T[sub max] data suggest that the gas generation begins at R[sub o] values of 0.53% and may begin at R[sub 0] values as low as 0.41% in some beds. New Albany Shale reservoirs contain both free gas in open-pore space and gas adsorbed on clay and kerogen surfaces. Natural fracturing is essential for effective reservoir permeability. Fractures are most common near structures such as faults, flexures, and buried carbonate banks. Based on limited data, fractures and joints have preferred orientations of 45-225[degrees] and 135-315[degrees]. Commercial production requires well stimulation to connect the well bore with the natural fracture system and to prop open pressure-sensitive near-borehole fractures. Current stimulations employ hydraulic fracture treatments using nitrogen and foam, with sand as a propping agent.

Patent analysis to identify shale gas development in China and the United States  

Science Journals Connector (OSTI)

Abstract Shale gas has become an increasingly important form of hydrocarbon energy, and related technologies reflect the geographical characteristics of the countries where the gas is extracted and stored. The United States (U.S.) produces most of the world’s shale gas, while China has the world’s largest shale gas reserves. In this research, we focused on identifying the trends in shale-gas related technologies registered to the United States Patent and Trademark Office (USPTO) and to the State Intellectual Property Office of the People’s Republic of China (SIPO) respectively. To cluster shale-gas related technologies, we text-mined the abstracts of patent specifications. It was found that in the U.S., the key advanced technologies were related to hydraulic fracturing, horizontal drilling, and slick water areas, whereas China had a focus on proppants. The results of our study are expected to assist energy experts in designing energy policies related to technology importation.

The possibility of induced seismic activity related to energy development projects, including shale gas, has drawn some public attention. * Although hydraulic fracturing releases energy deep beneath the surface to break rock, studies thus far indicate the energy released is generally not large enough to trigger a seismic event that could be felt on the surface. 1 * However, waste fluid disposal through underground injection can "pose some risk for induced seismicity." 2 * According to the National Academies of Sciences (NAS), accurately predicting seismic event magnitude or occurrence is not possible, in part because of a lack of comprehensive data on

Life-cycle analysis of shale gas and natural gas.  

SciTech Connect (OSTI)

The technologies and practices that have enabled the recent boom in shale gas production have also brought attention to the environmental impacts of its use. Using the current state of knowledge of the recovery, processing, and distribution of shale gas and conventional natural gas, we have estimated up-to-date, life-cycle greenhouse gas emissions. In addition, we have developed distribution functions for key parameters in each pathway to examine uncertainty and identify data gaps - such as methane emissions from shale gas well completions and conventional natural gas liquid unloadings - that need to be addressed further. Our base case results show that shale gas life-cycle emissions are 6% lower than those of conventional natural gas. However, the range in values for shale and conventional gas overlap, so there is a statistical uncertainty regarding whether shale gas emissions are indeed lower than conventional gas emissions. This life-cycle analysis provides insight into the critical stages in the natural gas industry where emissions occur and where opportunities exist to reduce the greenhouse gas footprint of natural gas.

Technically recoverable Devonian shale gas in Ohio  

SciTech Connect (OSTI)

The technically recoverable gas from Devonian shale (Lower and Middle Huron) in Ohio is estimated to range from 6.2 to 22.5 Tcf, depending on the stimulation method and pattern size selected. This estimate of recovery is based on the integration of the most recent data and research on the Devonian Age gas-bearing shales of Ohio. This includes: (1) a compilation of the latest geologic and reservoir data for the gas in-place; (2) analysis of the key productive mechanisms; and, (3) examination of alternative stimulation and production strategies for most efficiently recovering this gas. Beyond a comprehensive assembly of the data and calculation of the technically recoverable gas, the key findings of this report are as follows: a substantial volume of gas is technically recoverable, although advanced (larger scale) stimulation technology will be required to reach economically attractive gas production rates in much of the state; well spacing in certain of the areas can be reduced by half from the traditional 150 to 160 acres per well without severely impairing per-well gas recovery; and, due to the relatively high degree of permeability anisotropy in the Devonian shales, a rectangular, generally 3 by 1 well pattern leads to optimum recovery. Finally, although a consistent geological interpretation and model have been constructed for the Lower and Middle Huron intervals of the Ohio Devonian shale, this interpretation is founded on limited data currently available, along with numerous technical assumptions that need further verification. 11 references, 21 figures, 32 tables.

Optimization Models for Optimal Investment, Drilling, and Water Management in Shale Gas Supply Chains  

Science Journals Connector (OSTI)

Abstract This paper provides an overview of recent optimization models for shale gas production. We first describe a new mixed-integer optimization model for the design of shale gas infrastructures. It is aimed at optimizing the number of wells to drill, size and location of new gas processing plants, section and length of pipelines for gathering raw gas, delivering dry gas and natural gas liquids, power of gas compressors, and planning of freshwater consumption for well drilling and fracturing. We also describe a detailed operational mixed-integer linear model to optimize life cycle water use for well pads. The objective of the model is to determine the fracturing schedule that minimizes costs for freshwater consumption, transportation, treatment, storage, and disposal.

Computer simulation of hydraulic fracturing in shales-influences on primary migration  

SciTech Connect (OSTI)

Hydraulic tension fractures in a shale layer during sedimentation are simulated by use of computer techniques. The depth at which fractures form is directly proportional to the hydraulic conductivity and tensile strength, and inversely proportional to the rate of sedimentation and thickness of the shale layer. Hydraulic fractures may form at depths of oil generation to facilitate primary migration. This paper describes an attempt to simulate the process of hydraulic fracturing during burial and compaction of a shale layer by use of an elementary model. One objective is to investigate the role of various factors in hydraulic tension fracturing of shales in a tectonically relaxed area. Another objective is to see whether hydraulic fractures form at depths of oil generation.

Geologist examining the base of the Marcellus Shale at an outcrop near Bedford, PA. Gas-producing shales are predominantly composed of consolidated clay-sized particles with a high organic content. High subsurface pressures and temperatures convert the organic matter to oil and gas, which may migrate to conventional petroleum traps and also remains within the shale. However, the clay content severely limits gas and fluid flow within the shales. It is, therefore, necessary to understand the mineral and organic content, occurrence of natural fractures, thermal maturity, shale volumes, porosity

Barriers to the development of China's shale gas industry  

Science Journals Connector (OSTI)

Abstract Shale gas has become a promising onshore energy prospect in China. As much as the country aspires for greater energy independence through the use of its shale gas reserves, this process is slowed down by the combined weight of relative inexperience, lack of technology, geographical complexity, a hostile economic environment, a disincentive pipeline regime, and a complex land ownership system. To foster a better understanding of the current circumstances of the country's shale gas sector, a panel of scholars and experts shared their perspectives and insider knowledge on China's shale gas industry. It was found that some of the country's man-made institutional barriers are factors that have been hindering shale gas development in China, in addition to natural conditions such as water concerns and the complex geography of shale fields. Resolving this situation necessitates breaking the monopoly that major state-owned oil companies have over high-quality shale gas resources, opening pipeline network access, providing geological data, developing the domestic oil service market, creating conditions for fair competition between service providers, and improving the water management system.

Sustainable Development of the Shale Gas Supply Chain and the Optimal Drilling Strategy for Nonconventional Wells  

Science Journals Connector (OSTI)

Abstract We present a long-term MINLP planning model for the development of shale gas fields. A key decision is the drilling/fracturing strategy yielding the freshwater consumption profile, which is critical in waterscarce regions with high cumulative demand for water. Results show that the model can help companies to reduce freshwater consumption by optimally planning drilling operations, at the expense of small reductions in the net present value of the projects.

Cliffs Minerals, Inc. Eastern Gas Shales Project, Ohio No. 5 well - Lorain County. Phase II report. Preliminary laboratory results  

SciTech Connect (OSTI)

The US Department of Energy is funding a research and development program entitled the Eastern Gas Shales Project designed to increase commercial production of natural gas in the eastern United States from Middle and Upper Devonian Shales. The program's objectives are as follows: (1) to evaluate recoverable reserves of gas contained in the shales; (2) to enhanced recovery technology for production from shale gas reservoirs; and (3) to stimulate interest among commercial gas suppliers in the concept of producing large quantities of gas from low-yield, shallow Devonian Shale wells. The EGSP-Ohio No. 5 well was cored under a cooperative cost-sharing agreement between the Department of Energy (METC) and Columbia Gas Transmission Corporation. Detailed characterization of the core was performed at the Eastern Gas Shale Project's Core Laboratory. At the well site, suites of wet and dry hole geophysical logs were run. Characterization work performed at the Laboratory included photographic logs, lithologic logs, fracture logs, measurements of core color variation, and stratigraphic interpretation of the cored intervals. In addition samples were tested for physical properties by Michigan Technological University. Physical properties data obtained were for: directional ultrasonic velocity; directional tensile strength; strength in point load; and trends of microfractures.

A mathematical model for drainage and desorption area analysis during shale gas production  

Science Journals Connector (OSTI)

Abstract For shale gas production, more attention is paid to production decline analysis, pressure transient analysis, and flow mechanism in nano-scale matrix. A few studies were carried out to analyze the depth of drainage and desorption in shale gas reservoir. When simulating shale gas production performance, especially in the case of multi-stage fractured horizontal wells (MFHW), the understanding of depth of drainage can analyze the critical time of interference and its intensity, and the desorption area is also a key factor to calculate production contributed from adsorbed gas. In these regards, this study presents a semi-analytical solution with dynamic gas compressibility to predict drainage and desorption area for long term. An analytical simplification solution is obtained to predict for early production, which is accurate enough. Using the method of continuous succession of steady states, the approximation solution is in good agreement with the results of Fast-Matching Method (FMM). The results show that the seepage area of each fracture expands much faster in stimulated reservoir volume (SRV) than that in unstimulated area with an elliptic shape. Desorption area also expands fast in SRV but is limited in SRV due to ultra-tight properties in unstimulated area. It is also proved that critical desorption pressure (CDP) delays desorption which plays a significant role in area expansion. This approach turns out to be simple and efficient when applied to practical projects.

Water management technologies used by Marcellus Shale Gas Producers.  

SciTech Connect (OSTI)

Natural gas represents an important energy source for the United States. According to the U.S. Department of Energy's (DOE's) Energy Information Administration (EIA), about 22% of the country's energy needs are provided by natural gas. Historically, natural gas was produced from conventional vertical wells drilled into porous hydrocarbon-containing formations. During the past decade, operators have increasingly looked to other unconventional sources of natural gas, such as coal bed methane, tight gas sands, and gas shales.

An approach for assessing engineering risk from shale gas wells in the United States  

Science Journals Connector (OSTI)

Abstract In response to a series of “energy crises” in the 1970s, the United States government began investigating the potential of unconventional, domestic sources of energy to offset imported oil. Hydraulic fracturing applied to vertical tight sand and coal bed methane wells achieved some degree of success during a period of high energy prices in the early 1980s, but shale gas remained largely untapped until the late 1990s with the application of directional drilling, a mature technology adapted from deepwater offshore platforms that allowed horizontal wells to penetrate kilometers of organic-rich shale, and staged hydraulic fracturing, which created high permeability flowpaths from the horizontal wells into a much greater volume of the target formations than previous completion methods. These new engineering techniques opened up vast unconventional natural gas and oil reserves, but also raised concerns about potential environmental impacts. These include short-term and long-term impacts to air and water quality from rig operations, potential migration of gas, fluids and chemicals through the ground, and effects on small watersheds and landscapes from roads, pads and other surface structures. Engineering risk assessment commonly uses integrated assessment models (IAMs), which define sources of risk from features, events and processes. The risk from each system element is assessed using high-fidelity models. Output from these is simplified into reduced-order models, so that a large, integrated site performance assessment can be run using the IAM. The technique has been applied to engineered systems in geologic settings for sequestering carbon dioxide, and it is also applicable to shale gas, albeit with some modifications of the various system elements. Preliminary findings indicate that shale gas well drilling and hydraulic fracturing techniques are generally safe when properly applied. Incident reports recorded by state environmental agencies suggest that human error resulting from the disregard of prescribed practices is the greatest cause of environmental incidents. This can only be addressed through education, regulations and enforcement.

2, 2011 2, 2011 DOE's Early Investment in Shale Gas Technology Producing Results Today Washington, DC - A $92 million research investment in the 1970s by the U.S. Department of Energy (DOE) is today being credited with technological contributions that have stimulated development of domestic natural gas from shales. The result: more U.S. jobs, increased energy security, and higher revenues for states and the Federal Government. Spurred by the technological advancements resulting from this investment, U.S. shale gas production continues to grow, amounting to more than 8 billion cubic feet per day, or about 14 percent of the total volume of dry natural gas produced in the United States. DOE's Energy Information Administration (EIA) projects that the shale gas share of U.S. natural gas production will reach 45 percent by 2035. The EIA also projects that 827 trillion cubic feet of natural gas is now recoverable from U.S. shales using currently available technology-an increase of nearly 500 trillion cubic feet over earlier estimates.

Wellbore stability model for shale gas reservoir considering the coupling of multi-weakness planes and porous flow  

Science Journals Connector (OSTI)

Abstract Irregular wellbore collapse phenomena and accidents frequently occur during drilling operations in Longmaxi shale gas reservoir. Considering shale formation with natural cross beddings and fractures, we propose a multi-weakness plane instead of a single weakness plane failure model. Shale samples obtained from the Lower Silurian Longmaxi Strata of Sichuan Basin are investigated based on characterization and analysis of mineralogy, pore structure, sliding failure condition, and rock mechanics to study the impact of porous flow on jointed shale masses. Results show that Longmaxi gas shale is a brittle and fracture-prone material with poor hydrating capacity and extremely low permeability in rock matrices. Reduction of rock strength under porous flow may contribute to changes in intensity parameters of the weakness planes. Therefore, considering the failure of multi-weakness planes under porous flow, we present a wellbore stability model for shale gas reservoir. Two types of weakness plane distribution patterns are examined to discuss the effect of the occurrence, numbers, and water saturation of weakness planes. The results demonstrate that the number of weakness planes, difference in weakness plane occurrence, and diverse water saturation levels significantly affect wellbore stability during drilling.

Organic substances in produced and formation water from unconventional natural gas extraction in coal and shale  

Science Journals Connector (OSTI)

Abstract Organic substances in produced and formation water from coalbed methane (CBM) and gas shale plays from across the USA were examined in this study. Disposal of produced waters from gas extraction in coal and shale is an important environmental issue because of the large volumes of water involved and the variable quality of this water. Organic substances in produced water may be environmentally relevant as pollutants, but have been little studied. Results from five CBM plays and two gas shale plays (including the Marcellus Shale) show a myriad of organic chemicals present in the produced and formation water. Organic compound classes present in produced and formation water in CBM plays include: polycyclic aromatic hydrocarbons (PAHs), heterocyclic compounds, alkyl phenols, aromatic amines, alkyl aromatics (alkyl benzenes, alkyl biphenyls), long-chain fatty acids, and aliphatic hydrocarbons. Concentrations of individual compounds range from CBM samples) range from 50 to 100 ?g/L. Total dissolved organic carbon (TOC) in CBM produced water is generally in the 1–4 mg/L range. Excursions from this general pattern in produced waters from individual wells arise from contaminants introduced by production activities (oils, grease, adhesives, etc.). Organic substances in produced and formation water from gas shale unimpacted by production chemicals have a similar range of compound classes as CBM produced water, and TOC levels of about 8 mg/L. However, produced water from the Marcellus Shale using hydraulic fracturing has TOC levels as high as 5500 mg/L and a range of added organic chemicals including, solvents, biocides, scale inhibitors, and other organic chemicals at levels of 1000 s of ?g/L for individual compounds. Levels of these hydraulic fracturing chemicals and TOC decrease rapidly over the first 20 days of water recovery and some level of residual organic contaminants remain up to 250 days after hydraulic fracturing. Although the environmental impacts of the organics in produced water are not well defined, results suggest that care should be exercised in the disposal and release of produced waters containing these organic substances into the environment because of the potential toxicity of many of these substances.

Shale gas for the petrochemical industry: Incorporation of novel technologies  

Science Journals Connector (OSTI)

Abstract In this work, a new shale gas-based polygeneration system with essentially zero CO2 emissions is proposed that co-produces methanol, dimethyl ether (DME), olefins and power. The thermal and economic analysis of the proposed process is performed to determine the optimum product portfolio regarding current market prices. The optimization results show that production of methanol/DME and power can improve the performance of the olefin production section significantly. Therefore, the proposed plant can link the shale gas industry to the petrochemical sector efficiently and in an environmentally friendly way.

Quantitative dynamic analysis of gas desorption contribution to production in shale gas reservoirs  

Science Journals Connector (OSTI)

Abstract Unlike in conventional gas reservoirs, gas in shale reservoirs is stored mainly as free gas and adsorbed gas, and a small amount of dissolved gas. Well production from shale gas reservoirs usually exhibits sharply decline trend in the early period of production and then turns to long-term stable production at a relatively low rate, for which gas desorption contribution has been considered as a possible explanation. This study aims at providing an accurate evaluation of the contribution from gas desorption to dynamic production. Through incorporation of artificial component subdivision in a numerical simulator, the production contributions of the free and adsorbed gas can be obtained separately. This analysis approach is validated firstly and then applied to two case studies based on conceptual models of Barnett and Antrim Shale. The results show that desorbed gas dominates the production in Antrim Shale, while it only plays a small role in the production in Barnett Shale. The impact of permeability and initial gas saturation are also analyzed. In previous studies, numerical and analytical simulators were used to investigate the difference between the production performances with or without desorption, attributing the production increase to gas desorption. However, our study shows this treatment overestimates the contribution from gas desorption. This work provides a simple but accurate method for the dynamic analysis of desorption contribution to total production, contributing to reservoir resource assessment, the understanding of production mechanisms, and shale gas production simulation.

The Research on Dynamic Rules of Crack Extension during Hydraulic Fracturing for Oil Shale In-Situ Exploitation  

Science Journals Connector (OSTI)

It is a tough problem of low permeability for in-situ exploiting oil shale, while improving low permeability by hydraulic fracturing can generate permeable belts, and this is vital importance for oil exploitation. According to the layer property of oil shale, making full use of cohesive element to simulate, it established mathematical models for hydraulic fracturing and its fracturing rules, then conducted 3D numerical simulation. We can get: the shape of fractures is oval, and fractures extend along different directions are different, due to anisotropic property of oil shale and geostatic stress influenced, shown as from fig.9 to fig.10; the leak-off flow rate of fracturing fluid rises, reduces, and tends to a fixed value shown in fig.11; fracture opening is dependant on the volume and injection velocity of fluid injection and the rules of damage evolution and fracturing opening refer to fig.5, fig.6 and fig.13.

Petrology of the Devonian gas-bearing shale along Lake Erie helps explain gas shows  

SciTech Connect (OSTI)

Comprehensive petrologic study of 136 thin sections of the Ohio Shale along Lake Erie, when combined with detailed stratigraphic study, helps explain the occurrence of its gas shows, most of which occur in the silty, greenish-gray, organic poor Chagrin Shale and Three Lick Bed. Both have thicker siltstone laminae and more siltstone beds than other members of the Ohio Shale and both units also contain more clayshales. The source of the gas in the Chagrin Shale and Three Lick Bed of the Ohio Shale is believed to be the bituminous-rich shales of the middle and lower parts of the underlying Huron Member of the Ohio Shale. Eleven petrographic types were recognized and extended descriptions are provided of the major ones - claystones, clayshales, mudshales, and bituminous shales plus laminated and unlaminated siltstones and very minor marlstones and sandstones. In addition three major types of lamination were identified and studied. Thirty-two shale samples were analyzed for organic carbon, whole rock hydrogen and whole rock nitrogen with a Perkin-Elmer 240 Elemental Analyzer and provided the data base for source rock evaluation of the Ohio Shale.

Adsorption of methane and carbon dioxide on gas shale and pure mineral samples  

Science Journals Connector (OSTI)

Abstract We have measured methane and carbon dioxide adsorption isotherms at 40 °C on gas shale samples from the Barnett, Eagle Ford, Marcellus and Montney reservoirs. Carbon dioxide isotherms were included to assess its potential for preferential adsorption, with implications for its use as a fracturing fluid and/or storage in depleted shale reservoirs. To better understand how the individual mineral constituents that comprise shales contribute to adsorption, measurements were made on samples of pure carbon, illite and kaolinite as well. We were able to successfully fit all adsorption data for both gases in accordance with a Langmuir isotherm model. Our results show carbon dioxide to have approximately 2–3 times the adsorptive capacity of methane in both the pure mineral constituents and actual shale samples. In addition to obvious microstructural and compositional differences between real rocks and pure minerals, we hypothesize that water adsorption plays an important role in regulating surface area availability for other molecules to adsorb. The resultant volumetric swelling strain was also measured as a function of pressure/adsorption. We observe both clay and pure carbon to swell an amount that is approximately linearly proportional to the amount of adsorption.

Shale-gas scheduling for natural-gas supply in electric power production  

Science Journals Connector (OSTI)

Abstract This paper describes a novel integration of shale-gas supply in geographical proximity to natural-gas power production. Shale-gas reservoirs hold special properties that make them particularly suited for intermittent shut-in based production schemes. The proposed scheme argues that shale-gas reservoirs can be used to shift storage of gas used for meeting varying demands, from separate underground storage units operated by local distribution companies to the gas producers themselves. Based on this property, we present an economical attractive option for generating companies to increase their use of firm gas–supply contracts to the natural-gas power plants in order to secure a sufficient gas supply. The shale-well scheduling is formulated as profit-maximization model for well operators, in which we seek to include their main operational challenges, while preserving an economic incentive for the operators to adopt the proposed scheme. The resulting large-scale mixed integer linear program is solved by a Lagrangian relaxation scheme, with a receding horizon strategy implemented to handle operational uncertainties. We present the proposed optimization framework by illustrative case studies. The numerical results show a significant economic potential for the shale-well operators, and a viable approach for generating companies to secure a firm gas supply for meeting varying seasonal electricity demands.

Natural gas potential of the New Albany shale group (Devonian-Mississippian) in southeastern Illinois  

SciTech Connect (OSTI)

Data from geologic and geochemical studies of the New Albany shale group indicate that a 19-country area of southeastern Illinois is a favorable area to explore for gas in Devonian shale. Although gas shows in the shales have been encountered in several wells drilled in this area, no attempts were made to complete or evaluate a shale gas well until 1979. It is found that conventional rotary drilling with mud base drilling fluids likely causes extensive formation damage and may account for the paucity of gas shows and completion attempts in the Devonian shales; therefore, commercial production of shale gas in Illinois probably will require novel drilling completion techniques not commonly used by local operators. 16 refs.

Organic geochemistry of Mississippian shales (Bowland Shale Formation) in central Britain: Implications for depositional environment, source rock and gas shale potential  

Science Journals Connector (OSTI)

Abstract Marine Carboniferous shales are proven hydrocarbon source rocks in central Britain. In this contribution the depositional environment and shale gas/liquid potential of the lower Namurian part of the Bowland Shale Formation is studied using 77 thermally immature samples from the Duffield borehole. The Bowland Shale Formation comprises mudstone and turibidite lithofacies reflecting a pronounced sea level controlled cyclicity. The total organic carbon (TOC) content of the mudstones lithofacies (including marine bands) and of fine-grained rocks within the turibidite lithofacies varies between 1.3 and 9.1%. Hydrogen index (HI) values imply the presence of kerogen type III-II. According to biomarker ratios and bulk geochemical parameters, marine bands (maximum flooding surfaces, mfs) were deposited in deep water with slightly enhanced, normal, or slightly reduced salinity. Mudstones of the highstand systems tract (HST) were deposited in environments with normal to reduced salinity, whereas photic zone anoxia favoured the preservation of marine organic matter during deposition of the mfs and the HST. The supply of landplant debris increased during the HST. Turbidites and their non-calcareous mudstone equivalents represent lowstand systems tracts deposited in low salinity environments. Terrestrial organic matter dominates in turbiditic sediments, marine organisms prevail in time-equivalent mudstones. Mudstone beneath marine bands represents transgressive systems tracts when normal marine conditions and photic zone anoxia were re-established. The mudstone lithofacies exhibits a very good to excellent potential to generate conventional mixed oil and gas. TOC content of fine-grained rocks in the turbidite lithofacies depends on the amount of detrital minerals supplied from the south. Moreover, their organic matter is gas-prone. High TOC contents and large thicknesses of the mudstone lithofacies show that the Bowland Shale Formation holds a significant shale gas/liquid potential in areas with appropriate maturity. A relatively low average HI and high clay contents may have negative effects on the shale gas potential.

Deep, water-free gas potential is upside to New Albany shale play  

SciTech Connect (OSTI)

The New Albany shale of the Illinois basin contains major accumulations of Devonian shale gas, comparable both to the Antrim shale of the Michigan basin and the Ohio shale of the Appalachian basin. The size of the resource originally assessed at 61 tcf has recently been increased to between 323 tcf and 528 tcf. According to the 1995 US Geological Survey appraisal, New Albany shale gas represents 52% of the undiscovered oil and gas reserves of the Illinois basin, with another 45% attributed to coalbed methane. New Albany shale gas has been developed episodically for over 140 years, resulting in production from some 40 fields in western Kentucky, 20 fields in southern Indiana, and at least 1 field in southern Illinois. The paper describes two different plays identified by a GRI study and prospective areas.

The competition situation analysis of shale gas industry in China: Applying Porter’s five forces and scenario model  

Science Journals Connector (OSTI)

Abstract With the increasing of energy demand and environmental pressure, China government has been exploring a way to diversify energy supply. Shale gas development is becoming an important energy strategy in China in recent years due to giant shale gas reserves. However, the shale gas market is preliminarily shaping in China, so that many factors have great influence on its competition. To find these factors and to control them rationally is good for the cultivating Chinese shale gas market. Five forces model for industry analysis puts an insight into the competitive landscape of shale gas market by showing the forces of supplier power, buyer power, threat of substitution, barriers to entry, and degree of rivalry. Illustrating the key factors that affect competitive landscape provides a view into the situation of shale gas industry. The variation tendency of shale gas industry is analyzed by setting various scenarios. Finally some suggestions are proposed in order to keep the development of shale gas industry positively.

Gas seal for an in situ oil shale retort and method of forming thermal barrier  

DOE Patents [OSTI]

A gas seal is provided in an access drift excavated in a subterranean formation containing oil shale. The access drift is adjacent an in situ oil shale retort and is in gas communication with the fragmented permeable mass of formation particles containing oil shale formed in the in situ oil shale retort. The mass of formation particles extends into the access drift, forming a rubble pile of formation particles having a face approximately at the angle of repose of fragmented formation. The gas seal includes a temperature barrier which includes a layer of heat insulating material disposed on the face of the rubble pile of formation particles and additionally includes a gas barrier. The gas barrier is a gas-tight bulkhead installed across the access drift at a location in the access drift spaced apart from the temperature barrier.

OPTIMIZATION OF INFILL DRILLING IN NATURALLY-FRACTURED TIGHT-GAS RESERVOIRS  

SciTech Connect (OSTI)

A major goal of industry and the U.S. Department of Energy (DOE) fossil energy program is to increase gas reserves in tight-gas reservoirs. Infill drilling and hydraulic fracture stimulation in these reservoirs are important reservoir management strategies to increase production and reserves. Phase II of this DOE/cooperative industry project focused on optimization of infill drilling and evaluation of hydraulic fracturing in naturally-fractured tight-gas reservoirs. The cooperative project involved multidisciplinary reservoir characterization and simulation studies to determine infill well potential in the Mesaverde and Dakota sandstone formations at selected areas in the San Juan Basin of northwestern New Mexico. This work used the methodology and approach developed in Phase I. Integrated reservoir description and hydraulic fracture treatment analyses were also conducted in the Pecos Slope Abo tight-gas reservoir in southeastern New Mexico and the Lewis Shale in the San Juan Basin. This study has demonstrated a methodology to (1) describe reservoir heterogeneities and natural fracture systems, (2) determine reservoir permeability and permeability anisotropy, (3) define the elliptical drainage area and recoverable gas for existing wells, (4) determine the optimal location and number of new in-fill wells to maximize economic recovery, (5) forecast the increase in total cumulative gas production from infill drilling, and (6) evaluate hydraulic fracture simulation treatments and their impact on well drainage area and infill well potential. Industry partners during the course of this five-year project included BP, Burlington Resources, ConocoPhillips, and Williams.

Image taken from "Shale Gas: Applying Technology to Solve America's Energy Challenges," NETL, 2011. Hydraulic fracturing is a technique in which large volumes of water and sand, and small volumes of chemical additives are injected into low-permeability subsurface formations to increase oil or natural gas flow. The injection pressure of the pumped fluid creates fractures that enhance gas and fluid flow, and the sand or other coarse material holds the fractures open. Most of the injected fluid flows back to the wellbore and is pumped to the surface.

Sedimentology of gas-bearing Devonian shales of the Appalachian Basin  

SciTech Connect (OSTI)

The Eastern Gas Shales Project (1976-1981) of the US DOE has generated a large amount of information on Devonian shale, especially in the western and central parts of the Appalachian Basin (Morgantown Energy Technology Center, 1980). This report summarizes this information, emphasizing the sedimentology of the shales and how it is related to gas, oil, and uranium. This information is reported in a series of statements each followed by a brief summary of supporting evidence or discussion and, where interpretations differ from our own, we include them. We believe this format is the most efficient way to learn about the gas-bearing Devonian shales of the Appalachian Basin and have organized our statements as follows: paleogeography and basin analysis; lithology and internal stratigraphy; paleontology; mineralogy, petrology, and chemistry; and gas, oil, and uranium.

Interdisciplinary Investigation of CO2 Sequestration in Depleted Shale Gas Formations  

SciTech Connect (OSTI)

This project investigates the feasibility of geologic sequestration of CO2 in depleted shale gas reservoirs from an interdisciplinary viewpoint. It is anticipated that over the next two decades, tens of thousands of wells will be drilled in the 23 states in which organic-rich shale gas deposits are found. This research investigates the feasibility of using these formations for sequestration. If feasible, the number of sites where CO2 can be sequestered increases dramatically. The research embraces a broad array of length scales ranging from the ~10 nanometer scale of the pores in the shale formations to reservoir scale through a series of integrated laboratory and theoretical studies.

Theoretical fundamentals, critical issues, and adequate formulation of effective shale gas and condensate reservoir simulation  

Science Journals Connector (OSTI)

The issues of relevance to describing the storage and movement of hydrocarbon gas and condensate and water through extremely low permeability shale formations are reviewed. The shale rock is viewed as a heterogeneous quad-media continuum system. Each system has different wettability storage transport and connectivity characteristics. The hydrocarbon storage is considered as being in the free gas adsorbed gas and dissolved gas. The alteration of fluid properties and flow behavior under pore confinement are emphasized. For gas transport the effective mean-radii and apparent permeability as a function of pore-size distribution and gas adsorption are examined. The nonequilibrium fluid distribution effect produced by tortuous narrow flow paths is discussed. It is emphasized that these form the essential phenomena that must be taken into account for effective simulation of shale gas and condensate reservoirs.

Through the use of technology, U.S. oil and natural gas operators are converting previously uneconomic oil and natural gas resources into proved reserves and production. The Bakken Formation of the Williston Basin is a success story of horizontal drilling, fracturing, and completion technologies. The recent, highly productive oil field discoveries within the Bakken Formation did not come from venturing out into deep uncharted waters heretofore untapped by man, nor from blazing a trail into pristine environs never open to drilling before. Instead, success came from analysis of geologic data on a decades-old producing area, identification of uptapped resources, and application of the new drilling and completion technology necessary to exploit them. In short, it came from using technology

Fracture mechanics investigation of oil shale to aid in understanding the explosive fragmentation process. Final technical report, January 1983-July 1984  

SciTech Connect (OSTI)

This report summarizes goals and findings achieved in developing technologies to improve the overall efficiency of oil shale recovery processes. The objectives are to (a) develop theoretical fracture mechanics tools that are applicable to transversely isotropic materials such as sedimentary rock, more particularly oil shale; and (b) develop a fracture mechanics test procedure that can be conveniently used for rock specimens. Such a test procedure would: utilize the geometry of a typical rock core for the test; require a minimum amount of specimen machining; and provide meaningful, reproducible data that corresponds well to test data obtained from conventional fracture mechanics tests. Critical review of the state-of-the-art of fracture mechanics on layered rocks has been completed. Recommendations are made for innovative and promising methods for oil shale fracture mechanics. Numerical and analytical studies of mixed mode fracture mechanics are investigated. Transversely isotropic properties of oil shale are input using isoparametric finite elements with singular elements at the crack tip. The model is a plate with an edge crack whose angle with the edge varies to study the effect of mixed mode fracture under various conditions. The three-dimensional plate is in tension, and stress, energy methods are used in the fracture analysis. Precracked disks of oil shale cored perpendicular to bedding planes are analyzed numerically. Stress intensity factors are determined by (i) strain energy method, and (ii) elliptic simulation method. 47 refs., 12 figs., 1 tab.

Arguments Pro and Against Shale Gas Exploitation Worldwide and in Romania  

Science Journals Connector (OSTI)

Abstract Shale gas emerges as a new and important source of energy for the post - industrial world. It is assumed that countries that have considerable shale deposits will be better placed in the 21st century competition between states. The United States have one of biggest deposits of shale gas, underscores a domestic production “boom” and is on the verge of becoming a gas exporter in Western Europe. The United States still has few capabilities to export shale gas to Europe. It would have to build new liquefaction facilities to do that. On the other side, Russia is, for the moment, the energy giant of Europe, its massive exports of natural gas to the area, acting as a powerful political leverage especially on the eastern and central European space. But in Europe, at least 10 countries are believed to hold significant shale gas reserves; among them, Romania is assumed to have huge unconventional gas reserves, whose exploitation could ensure its medium-term energy independence, and combined with newly discovered gas in the Black Sea, and energy efficiency improvement measures, provide not only the energy independence but transform Romania into a regional power pole. The interesting fact is how each country in Europe, will choose to convert resources in shale gas reserves and to exploit them to the benefit of the economy, the society and the environment. Besides some clear positive effects (decreasing energy imports, creating a stronger negotiating position against external (fossil fuel) suppliers and diversifying Europe's energy mix) will shale gas extraction succeed to decrease gas bill for population, by reducing prices, or will it stick only to royalties and fees collection, as well as with some local social and economic effects, with the consequence of prolonged pollution or even potentially devastating effects on the environment? In order that gas-gas competition begins to act effectively and exert a strong competitive pressure on gas import prices in Europe (by changing their base and weaken the link with oil prices, up to a possible decoupling of it) it is necessary that Europe will benefit from a big inflow of gas supplies, shale gas included, from different sources than

The New Albany Shale (Devonian and Mississippian) is recognized as both a source rock and gas-producing reservoir in the Illinois basin. The first gas discovery was made in 1885, and was followed by the development of several small fields in Harrison County, Indiana, and Meade County, Kentucky. Recently, exploration for and production of New Albany gas has been encouraged by the IRS Section 29 tax credit. To identify technology gaps that have restricted the development of gas production form the shale gas resource in the basin, the Illinois Basin Consortium (IBC), composed of the Illinois, Indiana, and Kentucky geological surveys, is conducting a cooperative research project with the Gas Research Institute (GRI). An earlier study of the geological and geochemical aspects of the New Albany was conducted during 1976-1978 as part of the Eastern Gas Shales Project (EGSP) sponsored by the Department of Energy (DOE). The current IBC/GRI study is designed to update and reinterpret EGSP data and incorporate new data obtained since 1978. During the project, relationships between gas production and basement structures are being emphasized by constructing cross sections and maps showing thickness, structure, basement features, and thermal maturity. The results of the project will be published in a comprehensive final report in 1992. The information will provide a sound geological basis for ongoing shale-gas research, exploration, and development in the basin.

Integrated seismic study of naturally fractured tight gas reservoirs. Technical progress report, January 1, 1994--March 31, 1994  

SciTech Connect (OSTI)

The study area is located at the southern end of the Powder River Basin in Converse County in east-central Wyoming. It is a low permeability fractured site, with both gas and oil present. Reservoirs are highly compartmentalized due to the low permeabilities, and fractures provide the only practical drainage paths for production. The two formations of interest are: The Niobrara, a fractured shale and limey shale to chalk, which is a reservoir rock, but also its own source rock; and the Frontier, a tight sandstone lying directly below the Niobrara, brought into contact with it by an unconformity. This was the tenth quarter of the contract. During this quarter the investigators (1) continued processing the seismic data, and (2) continued modeling some of the P-wave amplitude anomalies that we see in the data.

The goal of the work this quarter has been to partition and high-grade the Greater Green River basin for exploration efforts in the Upper Cretaceous tight gas play and to initiate resource assessment of the basin. The work plan for the quarter of July 1-September 30, 1998 comprised three tasks: (1) Refining the exploration process for deep, naturally fractured gas reservoirs; (2) Partitioning of the basin based on structure and areas of overpressure; (3) Examination of the Kinney and Canyon Creek fields with respect to the Cretaceous tight gas play and initiation of the resource assessment of the Vermilion sub-basin partition (which contains these two fields); and (4) Initiation analysis of the Deep Green River Partition with respect to the Stratos well and assessment of the resource in the partition.

Gasification kinetics of six eastern shales in steam and synthesis gas atmospheres  

SciTech Connect (OSTI)

Gasification reactivities have been determined for six Eastern shales with conversions described by a model incorporating fast and slow gasification reactions. A simple model, based on Indiana New Albany shale, was developed to describe the fast and slow weight loss as well as the slow sulfur and organic carbon gasification rates. The slow sulfur and organic carbon reactions are described by rate equations that are first order in sulfur and organic carbon and include the steam pressure. Terms in the organic carbon rate expression account for hydrogen and carbon monoxide inhibition of the steam-carbon reaction. The fraction of shale species lost by fast and slow gasification and the rate of slow sulfur gasification are similar (and assumed to be equal) for the six Eastern shales studied. Eastern shale organic carbon reactivities are different and have been described with different kinetic parameters in the slow organic carbon gasification rate equation. The kinetic expressions developed for Eastern shale gasification are valid in steam and steam; synthesis gas mixtures and for residence times of more than 3 minutes. Gasification is described for temperature and pressure ranges of 1144 to 1311 K and 0.20 to 3.55 MPa, respectively.

Naturally fractured tight gas reservoir detection optimization  

SciTech Connect (OSTI)

The work plan for October 1, 1997 to September 30, 1998 consisted of investigation of a number of topical areas. These topical areas were reported in four quarterly status reports, which were submitted to DOE earlier. These topical areas are reviewed in this volume. The topical areas covered during the year were: (1) Development of preliminary tests of a production method for determining areas of natural fracturing. Advanced Resources has demonstrated that such a relationship exists in the southern Piceance basin tight gas play. Natural fracture clusters are genetically related to stress concentrations (also called stress perturbations) associated with local deformation such a faulting. The mechanical explanation of this phenomenon is that deformation generally initiates at regions where the local stress field is elevated beyond the regional. (2) Regional structural and geologic analysis of the Greater Green River Basin (GGRB). Application of techniques developed and demonstrated during earlier phases of the project for sweet-spot delineation were demonstrated in a relatively new and underexplored play: tight gas from continuous-typeUpper Cretaceous reservoirs of the Greater Green River Basin (GGRB). The effort included data acquisition/processing, base map generation, geophysical and remote sensing analysis and the integration of these data and analyses. (3) Examination of the Table Rock field area in the northern Washakie Basin of the Greater Green River Basin. This effort was performed in support of Union Pacific Resources- and DOE-planned horizontal drilling efforts. The effort comprised acquisition of necessary seismic data and depth-conversion, mapping of major fault geometry, and analysis of displacement vectors, and the development of the natural fracture prediction. (4) Greater Green River Basin Partitioning. Building on fundamental fracture characterization work and prior work performed under this contract, namely structural analysis using satellite and potential field data, the GGRB was divided into partitions that will be used to analyze the resource potential of the Frontier and Mesaverde Upper Cretaceous tight gas play. A total of 20 partitions were developed, which will be instrumental for examining the Upper Cretaceous play potential. (5) Partition Analysis. Resource assessment associated with individual partitions was initiated starting with the Vermilion Sub-basin and the Green River Deep (which include the Stratos well) partitions (see Chapter 5). (6) Technology Transfer. Tech transfer was achieved by documenting our research and presenting it at various conferences.

Stable isotope geochemistry of coal bed and shale gas and related production waters: A review  

Science Journals Connector (OSTI)

Abstract Coal bed and shale gas can be of thermogenic, microbial or of mixed origin with the distinction made primarily on the basis of the molecular and stable isotope compositions of the gases and production waters. Methane, ethane, carbon dioxide and nitrogen are the main constituents of coal bed and shale gases, with a general lack of C2+ hydrocarbon species in gases produced from shallow levels and more mature coals and shales. Evidence for the presence of microbial gas include ?13C–CH4 values less than ? 50‰, covariation of the isotope compositions of gases and production water, carbon and hydrogen isotope fractionations consistent with microbial processes, and positive ?13C values of dissolved inorganic carbon in production waters. The CO2-reduction pathway is distinguished from acetate/methyl-type fermentation by somewhat lower ?13C–CH4 and higher ?D–CH4, but can also have overlapping values depending on the openness of the microbial system and the extent of substrate depletion. Crossplots of ?13C–CH4 versus ?13C–CO2 and ?D–CH4 versus ?13C–H2O may provide a better indication of the origin of the gases and the dominant metabolic pathway than the absolute carbon and hydrogen isotope compositions of methane. In the majority of cases, microbial coal bed and shale gases have carbon and hydrogen isotope fractionations close to those expected for CO2 reduction. Primary thermogenic gases have ?13C–CH4 values greater than ? 50‰, and ?13C values that systematically increase from C1 to C4 and define a relatively straight line when plotted against reciprocal carbon number. Although coals and disseminated organic matter in shales represent a continuum as hydrocarbon source rocks, current data suggest a divergence between these two rock types at the high maturity end. In deep basin shale gas, reversals or rollovers in molecular and isotopic compositions are increasingly reported in what is effectively a closed shale system as opposed to the relative openness in coal measure environments. Detailed geochemical studies of coal bed and shale gas and related production waters are essential to determine not only gas origins but also the dominant methanogenic pathway in the case of microbial gases.

ANALYSIS OF DEVONIAN BLACK SHALES IN KENTUCKY FOR POTENTIAL CARBON DIOXIDE SEQUESTRATION AND ENHANCED NATURAL GAS PRODUCTION  

SciTech Connect (OSTI)

Proposed carbon management technologies include geologic sequestration of CO{sub 2}. A possible, but untested, strategy is to inject CO{sub 2} into organic-rich shales of Devonian age. Devonian black shales underlie approximately two-thirds of Kentucky and are generally thicker and deeper in the Illinois and Appalachian Basin portions of Kentucky. The Devonian black shales serve as both the source and trap for large quantities of natural gas; total gas in place for the shales in Kentucky is estimated to be between 63 and 112 trillion cubic feet. Most of this natural gas is adsorbed on clay and kerogen surfaces, analogous to the way methane is stored in coal beds. In coals, it has been demonstrated that CO{sub 2} is preferentially adsorbed, displacing methane at a ratio of two to one. Black shales may similarly desorb methane in the presence of CO{sub 2}. If black shales similarly desorb methane in the presence of CO{sub 2}, the shales may be an excellent sink for CO{sub 2} with the added benefit of serving to enhance natural gas production. The concept that black, organic-rich Devonian shales could serve as a significant geologic sink for CO{sub 2} is the subject this research. To accomplish this investigation, drill cuttings and cores will be selected from the Kentucky Geological Survey Well Sample and Core Library. CO{sub 2} adsorption analyses will be performed in order to determine the gas-storage potential of the shale and to identify shale facies with the most sequestration potential. In addition, new drill cuttings and sidewall core samples will be acquired to investigate specific black-shale facies, their uptake of CO{sub 2}, and the resultant displacement of methane. Advanced logging techniques (elemental capture spectroscopy) will be used to investigate possible correlations between adsorption capacity and geophysical log measurements.

Development and application of type curves for pressure transient analysis of horizontal wells in shale gas reservoirs  

Science Journals Connector (OSTI)

Even though significant progresses have been made in the past few years, there appears to be a lack of information regarding the characterisation of shale gas formations. A major purpose of this study is to demonstrate impacts of horizontal well geometries and gas flow parameters as well as shale gas reservoir system on horizontal well production behaviour and flow regime on pressure transient analysis (PTA). Extensive numerical simulations were conducted to model transient pressure behaviour of a horizontal well and apply the results to well test analysis in shale gas reservoirs. Based on the results from numerical simulations, a set of type curves have been developed in terms of dimensionless pseudopressure and time. Results from type curve matching for synthetic pressure data in shale gas reservoirs demonstrate that the conventional analysis approach may still be applicable for the quantitative analysis on the transient gas flow behaviour and determination of formation properties.

A Green River shale from Colorado and a New Albany shale from Kentucky were retorted in the Pacific Northwest Laboratory 6-kg bench-scale retort at 1 to 2C/min and at 10C/min to maximum temperatures of 500 and 750C under a nitrogen sweep gas. The product streams were analyzed using a variety of methods including Zeeman atomic aabsortion spectroscopy, microwave-induced helium plasma spectroscopy, x-ray fluorescence, instrumental neutron activation analysis, high-pressure liquid and silica gel column chromatography, and mercury cold vapor atomic absorption. The results obtained using these analytical methods indicate the the distribution of mercury, arsenic, and selenium in the product stream is a function of oil shale type, heating rates, and maximum retorting temperatures. 23 refs., 15 figs., 5 tabs.

Porosity of coal and shale: Insights from gas adsorption and SANS/USANS techniques  

SciTech Connect (OSTI)

Two Pennsylvanian coal samples (Spr326 and Spr879-IN1) and two Upper Devonian-Mississippian shale samples (MM1 and MM3) from the Illinois Basin were studied with regard to their porosity and pore accessibility. Shale samples are early mature stage as indicated by vitrinite reflectance (R{sub o}) values of 0.55% for MM1 and 0.62% for MM3. The coal samples studied are of comparable maturity to the shale samples, having vitrinite reflectance of 0.52% (Spr326) and 0.62% (Spr879-IN1). Gas (N{sub 2} and CO{sub 2}) adsorption and small-angle and ultrasmall-angle neutron scattering techniques (SANS/USANS) were used to understand differences in the porosity characteristics of the samples. The results demonstrate that there is a major difference in mesopore (2-50 nm) size distribution between the coal and shale samples, while there was a close similarity in micropore (<2 nm) size distribution. Micropore and mesopore volumes correlate with organic matter content in the samples. Accessibility of pores in coal is pore-size specific and can vary significantly between coal samples; also, higher accessibility corresponds to higher adsorption capacity. Accessibility of pores in shale samples is low.

Measured adsorption isotherm data range from 37.5 to 2,077.6 standard cubic feet of CO{sub 2} per ton (scf/ton) of shale. At 500 psia, adsorption capacity of the Lower Huron Member of the shale is 72 scf/ton. Initial estimates indicate a sequestration capacity of 5.3 billion tons CO{sub 2} in the Lower Huron Member of the Ohio shale in parts of eastern Kentucky and as much as 28 billion tons total in the deeper and thicker portions of the Devonian shales in Kentucky. The black shales of Kentucky could be a viable geologic sink for CO{sub 2}, and their extensive occurrence in Paleozoic basins across North America would make them an attractive regional target for economic CO{sub 2} storage and enhanced natural gas production.

ANALYSIS OF DEVONIAN BLACK SHALES IN KENTUCKY FOR POTENTIAL CARBON DIOXIDE SEQUESTRATION AND ENHANCED NATURAL GAS PRODUCTION  

SciTech Connect (OSTI)

CO{sub 2} emissions from the combustion of fossil fuels have been linked to global climate change. Proposed carbon management technologies include geologic sequestration of CO{sub 2}. A possible, but untested, sequestration strategy is to inject CO{sub 2} into organic-rich shales. Devonian black shales underlie approximately two-thirds of Kentucky and are thicker and deeper in the Illinois and Appalachian Basin portions of Kentucky than in central Kentucky. The Devonian black shales serve as both the source and trap for large quantities of natural gas; total gas in place for the shales in Kentucky is estimated to be between 63 and 112 trillion cubic feet. Most of this natural gas is adsorbed on clay and kerogen surfaces, analogous to methane storage in coal beds. In coals, it has been demonstrated that CO{sub 2} is preferentially adsorbed, displacing methane. Black shales may similarly desorb methane in the presence of CO{sub 2}. The concept that black, organic-rich Devonian shales could serve as a significant geologic sink for CO{sub 2} is the subject of current research. To accomplish this investigation, drill cuttings and cores were selected from the Kentucky Geological Survey Well Sample and Core Library. Methane and carbon dioxide adsorption analyses are being performed to determine the gas-storage potential of the shale and to identify shale facies with the most sequestration potential. In addition, sidewall core samples are being acquired to investigate specific black-shale facies, their potential CO{sub 2} uptake, and the resulting displacement of methane. Advanced logging techniques (elemental capture spectroscopy) are being investigated for possible correlations between adsorption capacity and geophysical log measurements. For the Devonian shale, average total organic carbon is 3.71 percent (as received) and mean random vitrinite reflectance is 1.16. Measured adsorption isotherm data range from 37.5 to 2,077.6 standard cubic feet of CO{sub 2} per ton (scf/ton) of shale. At 500 psia, adsorption capacity of the Lower Huron Member of the shale is 72 scf/ton. Initial estimates indicate a sequestration capacity of 5.3 billion tons CO{sub 2} in the Lower Huron Member of the Ohio shale in parts of eastern Kentucky and as much as 28 billion tons total in the deeper and thicker portions of the Devonian shales in Kentucky. The black shales of Kentucky could be a viable geologic sink for CO{sub 2}, and their extensive occurrence in Paleozoic basins across North America would make them an attractive regional target for economic CO{sub 2} storage and enhanced natural gas production.

Integrated seismic study of naturally fractured tight gas reservoirs. Technical progress report, April 1, 1993--June 31, 1993  

SciTech Connect (OSTI)

This was the seventh quarter of the contract. During this quarter we (1) continued the large task of processing the seismic data, (2) collected additional geological information to aid in the interpretation, (3) tied the well log data to the seismic via generation of synthetic seismograms, (4) began integrating regional structural information and fracture trends with our observations of structure in the study area, (5) began constructing a velocity model for time-to-depth conversion and subsequent AVO and raytrace modeling experiments, and (6) completed formulation of some theoretical tools for relating fracture density to observed elastic anisotropy. The study area is located at the southern end of the Powder River Basin in Converse County in east-central Wyoming. It is a low permeability fractured site, with both gas and oil present. Reservoirs are highly compartmentalized due to the low permeabilities, and fractures provide the only practical drainage paths for production. The two formations of interest are: The Niobrara: a fractured shale and limey shale to chalk, which is a reservoir rock, but also its own source rock. The Frontier: a tight sandstone lying directly below the Niobrara, brought into contact with it by an unconformity. A basemap is presented with the seismic lines being analyzed for this project plus locations of 13 wells that we are using to supplement the analysis. The arrows point to two wells for which we have constructed synthetic seismograms.

Reservoir evaluation of the Lower Silurian Longmaxi Formation shale gas in the southern Sichuan Basin of China  

Science Journals Connector (OSTI)

Abstract The Lower Silurian Longmaxi Formation (the Palaeozoic) is organic-rich (black) shale in the southern Sichuan Basin (the Yangtze Plate) of China. This study analyses the lateral extent and thickness, burial depth, total organic carbon content and thermal maturity of the Longmaxi Formation black shale as the key features of the shale gas reservoir. The thickness of the black shale ranges from 10 to 170 m. The thickest reservoir is located in Changning-Naxi-Yongchuan region. The TOC of the shale at the bottom of the formation (50-m thickness) is above 2.0%. The lateral distribution of TOC varies with the lateral distribution of thickness, with the maximum TOC in the Gongxian-Luzhou-Yongchuan region. The burial depth ranges from 2000 to 4500 m. The shale is thermally over mature. The evaluation of reservoir characteristics indicates that the Longmaxi Formation has conditions appropriate for shale gas accumulation and thus resource potential in the southern Sichuan Basin of China. The objective of this preliminary evaluation of the reservoir characteristics is to locate potential areas favourable for exploration. The most favourable areas are defined here as those where the thickness of black shale is more than 100 m and the burial depth is less than 3000 m; these cover approximately 12,600 km2. The most favourable areas, which cover an area of approximately 5100 km2, are located in the northeast Luzhou region.

Integrated seismic study of naturally fractured tight gas reservoirs. Technical progress report, January 1, 1993--March 31, 1993  

SciTech Connect (OSTI)

During this quarter we (1) received the last of the field tapes and survey information for the seismic field data acquisition which was finished at the very end of the previous quarter, (2) began the large task of processing the seismic data, (3) collected well logs and other informination to aid in the interpretation, and (4) initiated some seismic modeling studies. As already reported, the field data acquisition was at Amoco`s Powder River Basin site in southeast Wyoming. This is a low permeability fractured site, with both gas and oil present. The reservoir is highly compartmentalized, due to the low permeability, with the fractures providing the only practical drainage paths for production. The two formations of interest are: The Niobrara: a fractured shale and limey shale to chalk, which is a reservoir rock, but also its own source rock. The Frontier: a tight sandstone lying directly below the Niobrara, brought into contact with it by an unconformity. The fractures are thought to lie in a roughly northwest-southeast trend, along the strike of a flexure, which forms one of the boundaries of the basin.

Demonstration projects for coalbed methane and Devonian shale gas: Final report. [None  

SciTech Connect (OSTI)

In 1979, the US Department of Energy provided the American Public Gas Association (APGA) with a grant to demonstrate the feasibility of bringing unconventional gas such as methane produced from coalbeds or Devonian Shale directly into publicly owned utility system distribution lines. In conjunction with this grant, a seven-year program was initiated where a total of sixteen wells were drilled for the purpose of providing this untapped resource to communities who distribute natural gas. While coalbed degasification ahead of coal mining was already a reality in several parts of the country, the APGA demonstration program was aimed at actual consumer use of the gas. Emphasis was therefore placed on degasification of coals with high methane gas content and on utilization of conventional oil field techniques. 13 figs.

Comment on “Modeling and prediction of natural gas fracking pad landscapes in the Marcellus Shale region, USA” by Qingming Meng  

Science Journals Connector (OSTI)

Abstract In modeling and prediction of natural gas fracking pad landscapes in the Marcellus Shale region, USA, the author asserts that landscape and environmental characteristics are the driving factors behind the siting of natural gas pads in the southwestern area of the Marcellus Shale, Pennsylvania, USA. In the article, the author largely dismisses the importance of geology for site prediction. Although the study is useful for understanding landscape characteristics in a small area of the Marcellus Shale, his premise that “the key variables for natural gas fracking can be landscape and environmental variables rather than geological variables” is flawed and thus could lead to erroneous assumptions when creating land use plans. A more reasonable assumption is that the surface siting of natural gas wells is secondary to geologic considerations, as the current topography bears little influence on the geology.

§ Social and Environmental Research Institute, 664 Main Street, Suite 47, Amherst, Massachusetts 01002, United States ... Emerging technologies pose particularly strong challenges for risk governance when they have multidimensional and inequitable impacts, when there is scientific uncertainty about the technology and its risks, when there are strong value conflicts over the perceived benefits and risks, when decisions must be made urgently, and when the decision making environment is rife with mistrust. ... In what is often called “unconventional” development of shale gas by technical experts and referred to colloquially simply as “fracking”, vertical wells are drilled to depths of up to 4 km before lateral drilling, which may extend up to 3 km. ...

ANALYSIS OF DEVONIAN BLACK SHALES IN KENTUCKY FOR POTENTIAL CARBON DIOXIDE SEQUESTRATION AND ENHANCED NATURAL GAS PRODUCTION  

SciTech Connect (OSTI)

Devonian gas shales underlie approximately two-thirds of Kentucky. In the shale, natural gas is adsorbed on clay and kerogen surfaces. This is analogous to methane storage in coal beds, where CO{sub 2} is preferentially adsorbed, displacing methane. Black shales may similarly desorb methane in the presence of CO{sub 2}. Drill cuttings from the Kentucky Geological Survey Well Sample and Core Library were sampled to determine CO{sub 2} and CH{sub 4} adsorption isotherms. Sidewall core samples were acquired to investigate CO{sub 2} displacement of methane. An elemental capture spectroscopy log was acquired to investigate possible correlations between adsorption capacity and mineralogy. Average random vitrinite reflectance data range from 0.78 to 1.59 (upper oil to wet gas and condensate hydrocarbon maturity range). Total organic content determined from acid-washed samples ranges from 0.69 to 14 percent. CO{sub 2} adsorption capacities at 400 psi range from a low of 14 scf/ton in less organic-rich zones to more than 136 scf/ton. There is a direct correlation between measured total organic carbon content and the adsorptive capacity of the shale; CO{sub 2} adsorption capacity increases with increasing organic carbon content. Initial estimates based on these data indicate a sequestration capacity of 5.3 billion tons of CO{sub 2} in the Lower Huron Member of the Ohio Shale of eastern Kentucky and as much as 28 billion tons total in the deeper and thicker parts of the Devonian shales in Kentucky. Should the black shales of Kentucky prove to be a viable geologic sink for CO{sub 2}, their extensive occurrence in Paleozoic basins across North America would make them an attractive regional target for economic CO{sub 2} storage and enhanced natural gas production.

Evaluation of Devonian shale reservoir using multi-well pressure transient testing data  

SciTech Connect (OSTI)

A multi-well test program designed to study the gas production mechanisms of the eastern Devonian shale reservoirs was completed. Two offset wells were drilled as observation wells in Meigs County, OH. The results indicated a complete anisotropic, layered reservoir system which implies directional gas flow and orientation of natural fractures. This study has provided an insight into the production behavior of reservoirs. It will aid future development of shale gas by optimizing well spacing and understanding of the gas release mechanisms of the Devonian shalings. 33 refs.

Paleozoic oil/gas shale reservoirs in southern Tunisia: An overview  

Science Journals Connector (OSTI)

Abstract During these last years, considerable attention has been given to unconventional oil and gas shale in northern Africa where the most productive Paleozoic basins are located (e.g. Berkine, Illizi, Kufra, Murzuk, Tindouf, Ahnet, Oued Mya, Mouydir, etc.). In most petroleum systems, which characterize these basins, the Silurian played the main role in hydrocarbon generation with two main ‘hot’ shale levels distributed in different locations (basins) and their deposition was restricted to the Rhuddanian (Lllandovery: early Silurian) and the Ludlow–Pridoli (late Silurian). A third major hot shale level had been identified in the Frasnian (Upper Devonian). Southern Tunisia is characterized by three main Paleozoic sedimentary basins, which are from North to South, the southern Chotts, Jeffara and Berkine Basin. They are separated by a major roughly E–W trending lower Paleozoic structural high, which encompass the Mehrez-Oued Hamous uplift to the West (Algeria) and the Nefusa uplift to the East (Libya), passing by the Touggourt-Talemzane-PGA-Bou Namcha (TTPB) structure close to southern Tunisia. The forementioned major source rocks in southern Tunisia are defined by hot shales with elevated Gamma ray values often exceeding 1400 API (in Hayatt-1 well), deposited in deep water environments during short lived (c. 2 Ma) periods of anoxia. In the course of this review, thickness, distribution and maturity maps have been established for each hot shale level using data for more than 70 wells located in both Tunisia and Algeria. Mineralogical modeling was achieved using Spectral Gamma Ray data (U, Th, K), SopectroLith logs (to acquire data for Fe, Si and Ti) and Elemental Capture Spectroscopy (ECS). The latter technique provided data for quartz, pyrite, carbonate, clay and Sulfur. In addition to this, the Gamma Ray (GR), Neutron Porosity (?N), deep Resistivity (Rt) and Bulk Density (?b) logs were used to model bulk mineralogy and lithology. Biostratigraphic and complete geochemical review has been undertaken from published papers and unpublished internal reports to better assess these important source intervals.

Evaluation of Devonian shale potential in Illinois, Indiana, and western Kentucky  

SciTech Connect (OSTI)

Potential natural gas resources in the New Albany Shale of the Illinois basin may be related to five key factors: relative organic content of the shale; relative thickness of the organically-rich shale; thermal maturity as related to depth of burial; presence of natural fractures; and type of organic matter. The shale that is organically richest is in southeastern Illinois and in most of the Indiana and Kentucky portions of the Illinois basin. The shales are thickest (about 400 feet) near the center of the basin in southeastern Illinois, southwestern Indiana, and adjacent parts of Kentucky. The area is deeply buried by younger rocks, and the organic matter has the highest thermal maturity. In addition, natural fault-induced fractures in the shale, which may aid in collecting gas from a larger volume of shale, may be present, since major faults along the Rough Creek Lineament and Wabash Valley Fault System cross the deeper part of the basin. Thus, this area near the basin center where the shale is thickest and rich organically and where fault-induced fractures may be present has the greatest potential for natural-gas resources. The eastern side of the basin, where the shale is organic-rich but thin, may have poor to moderate potential for additional discoveries of small gas fields similar to those found in the past. In western Illinois and the northern part of the basin, the potential is poor, because the organic content of the dominantly greenish-gray shale in this area is low. More exploration will be required to properly evaluate potential resources of natural gas that may exist in the New Albany Shale.

A method for calculating economic critical depth of shale gas resources in China via break-even analysis  

Science Journals Connector (OSTI)

Abstract Target depth is a key measure of the commercial viability of a shale gas prospect. Although much research has been conducted in the shale gas techno-economic appraisal field, no reports are available on the economic critical depth (ECD) of shale gas resources. The present work aims at establishing a model for calculating the ECD using the break-even analysis—the reverse of calculating the net present value (NPV)—such that the break-even ECD occurs at zero NPV. The ECD is sensitive to production uncertainty, depending on the initial production (IP) rate and the production decline rate. Examples indicate that these have a marked effect on ECD based on current technology, gas price and exploitation policy, with the IP rate having the more pronounced effect. When the IP rate varies between 2.5 and 5.5 × 104 m3/day based on the fitted production decline trend from a pilot area in China, the corresponding ECD varies from 898 m to 3997 m. The ECD is thus able to rule out non-commercial shale gas prospects quickly.

Comparisons of pore size distribution: A case from the Western Australian gas shale formations  

Science Journals Connector (OSTI)

Abstract Pore structure of shale samples from Triassic Kockatea and Permian Carynginia formations in the Northern Perth Basin, Western Australia is characterized. Transport properties of a porous media are regulated by the topology and geometry of inter-connected pore spaces. Comparisons of three laboratory experiments are conducted on the same source of samples to assess such micro-, meso- and macro-porosity: Mercury Injection Capillary Pressure (MICP), low field Nuclear Magnetic Resonance (NMR) and nitrogen adsorption (N2). High resolution FIB/SEM image analysis is used to further support the experimental pore structure interpretations at sub-micron scale. A dominating pore throat radius is found to be around 6 nm within a mesopore range based on MICP, with a common porosity around 3%. This relatively fast experiment offers the advantage to be reliable on well chips or cuttings up the pore throat sizes >2 nm. However, nitrogen adsorption method is capable to record pore sizes below 2 nm through the determination of the total pore volume from the quantity of vapour adsorbed at relative pressure. But the macro-porosity and part of the meso-porosity is damaged or even destroyed during the sample preparation. BET specific surface area results usually show a narrow range of values from 5 to 10 m2/g. Inconsistency was found in the pore size classification between MICP and N2 measurements mostly due to their individual lower- and upper-end pore size resolution limits. The water filled pores disclosed from NMR T2 relaxation time were on average 30% larger than MICP tests. Evidence of artificial cracks generated from the water interactions with clays after re-saturation experiments could explain such porosity over-estimation. The computed pore body to pore throat ratio extracted from the Timur–Coates NMR model, calibrated against gas permeability experiments, revealed that such pore geometry directly control the permeability while the porosity and pore size distribution remain similar between different shale gas formations and/or within the same formation. The combination of pore size distribution obtained from MICP, N2 and NMR seems appropriate to fully cover the range of pore size from shale gas and overcome the individual method limits.

Process for oil shale retorting  

DOE Patents [OSTI]

Particulate oil shale is subjected to a pyrolysis with a hot, non-oxygenous gas in a pyrolysis vessel, with the products of the pyrolysis of the shale contained kerogen being withdrawn as an entrained mist of shale oil droplets in a gas for a separation of the liquid from the gas. Hot retorted shale withdrawn from the pyrolysis vessel is treated in a separate container with an oxygenous gas so as to provide combustion of residual carbon retained on the shale, producing a high temperature gas for the production of some steam and for heating the non-oxygenous gas used in the oil shale retorting process in the first vessel. The net energy recovery includes essentially complete recovery of the organic hydrocarbon material in the oil shale as a liquid shale oil, a high BTU gas, and high temperature steam.

Abstract HF-1 well of Pengye is a sidetracking horizontal well for shale gas development, the directional segment of the well is long, high requirements for well trajectory control of the directional segment in construction process. In allusion to the features and challenges of this well drilling, this paper introduces the application of slide steering drilling system and rotary steerable drilling system in this well, including analyzing all these tool basic principle, the characteristics and field application. The analysis shows that using different angel screw drill tool can meet the needs of increasing hole angle, steadying hole angle and adjusting the orientation; Adoption of EZ-Pilot steerable rotary system solves the problem of remarkable resistance and low degree of hole cleanness in long horizontal section, and satisfies the requirement of drilling and completion of the well. The system also shows the desirable performance in improving ROP and hole quality.

Naturally fractured tight gas reservoir detection optimization  

SciTech Connect (OSTI)

During this quarter, work began on the regional structural and geologic analysis of the greater Green River basin (GGRB) in southwestern Wyoming, northwestern Colorado and northeastern Utah. The ultimate objective of the regional analysis is to apply the techniques developed and demonstrated during earlier phases of the project to sweet-spot delineation in a relatively new and underexplored play: tight gas from continuous-type Upper Cretaceous reservoirs of the GGRB. The primary goal of this work is to partition and high-grade the greater Green River basin for exploration efforts in the Cretaceous tight gas play. The work plan for the quarter of January 1, 1998--March 31, 1998 consisted of three tasks: (1) Acquire necessary data and develop base map of study area; (2) Process data for analysis; and (3) Initiate structural study. The first task and second tasks were completed during this reporting period. The third task was initiated and work continues.

Geological controls on matrix permeability of Devonian Gas Shales in the Horn River and Liard basins, northeastern British Columbia, Canada  

Science Journals Connector (OSTI)

Controls of matrix permeability are investigated for Devonian Gas Shales from the Horn River and Liard basins in northeastern British Columbia, Canada. Mineralogy is varied with high carbonate, high quartz and moderate quartz, carbonate and clay rich strata. Quartz content varies between 2 and 73%, carbonate varies between 1 and 93% and clay varies between 3 and 33%. The TOC content ranges between 0.3 and 6 wt.% and porosity varies between about 1 and 7%. For Horn River basin samples, quartz is mainly biogenic in origin derived from radiolarians. TOC content increases with the quartz content suggesting the TOC and quartz both are derived from siliceous phytoplankton. A positive relationship between porosity and quartz content is due to the positive relationship between quartz and TOC. Matrix permeability parallel to bedding varies between 7.5E? 02 and 7.1E? 07 mD at an effective stress of 15 MPa. Variation in permeability is due to a complex combination of factors that includes origin and distribution of minerals, pore?size distribution and fabric. Mercury intrusion capillary curves indicate that the higher matrix permeability values (> 2E? 03 mD) occurs in samples that contain interconnected pore apertures greater than 16 ?m even when these samples may contain less macropores than low permeability samples. The fabric of high permeability samples can be either isotropic or anisotropic; however permeability of anisotropic samples is more sensitive to changes in effective stress than isotropic samples. More highly anisotropic samples contain moderate amounts of quartz, carbonate and in some, clay. High permeability samples that contain a more balanced ratio between micro-, meso- and macroporosity would not only have faster flow rates but also greater access to sorbed gas within the microporosity compared to samples that lack mesopores. Several Muskwa samples compared to Evie and Besa River samples contain higher quartz, moderate clay and high TOC content coupled with high permeability, less sensitivity to effective stress and balanced ratios between micro-, meso- and macroporosity would be a lower exploration risk due a greater propensity to fracture, the ability to produce and store hydrocarbons due to higher TOC contents and greater communication between macropores and micropores in the organic and clay fractions.

DEVELOPMENT OF GLASS AND GLASS CERAMIC PROPPANTS FROM GAS SHALE WELL DRILL CUTTINGS  

SciTech Connect (OSTI)

The objective of this study was to develop a method of converting drill cuttings from gas shale wells into high strength proppants via flame spheroidization and devitrification processing. Conversion of drill cuttings to spherical particles was only possible for small particle sizes (< 53 {micro}m) using a flame former after a homogenizing melting step. This size limitation is likely to be impractical for application as conventional proppants due to particle packing characteristics. In an attempt to overcome the particle size limitation, sodium and calcium were added to the drill cuttings to act as fluxes during the spheroidization process. However, the flame former remained unable to form spheres from the fluxed material at the relatively large diameters (0.5 - 2 mm) targeted for proppants. For future work, the flame former could be modified to operate at higher temperature or longer residence time in order to produce larger, spherical materials. Post spheroidization heat treatments should be investigated to tailor the final phase assemblage for high strength and sufficient chemical durability.

Microbial degradation of sedimentary organic matter associated with shale gas and coalbed methane in eastern Illinois Basin (Indiana), USA  

Science Journals Connector (OSTI)

Molecular biodegradation indices for extracts from five Pennsylvanian coals and six New Albany Shale (Devonian – Mississippian) samples from the eastern part of the Illinois Basin help constrain relationships between the degradation of biomarkers and the generation of coalbed methane and shale gas. Investigation of these gas source rocks of varying thermal maturity from different depths facilitates evaluation of the association of microbial degradation with biogenic gas formation distinct from thermogenic processes. Extensive biodegradation of both aliphatic and aromatic hydrocarbons is observed in the coal extracts, whereas in shale extracts only short-chain (C15–C19) n-alkanes from the shallowest depth appear to be microbially altered with minimal evidence for losses of acyclic isoprenoid alkanes and aromatic hydrocarbons. By contrast, biodegradation of aromatic hydrocarbons, specifically alkylated naphthalenes and phenanthrenes, occurs in coal extracts in concert with losses of n-alkanes attributable to microbial activity. Thus, the progress of hydrocarbon biodegradation in coals differs from the sequence recognized in petroleum where the effects of microbial alteration of aromatic constituents only appear after extensive losses of aliphatic compounds. The extent of hydrocarbon biodegradation in these coals also decreases with depth, as recorded by the ?(nC25–nC30) index (i.e. abundance relative to 17?(H), 21?(H)-hopane) among the aliphatic constituents and several aromatic compounds (methyl-, dimethyl-, and trimethylnaphthalenes, phenanthrene, and trimethyl- and tetramethylphananthrenes). However, the depth variations in the distributions of aliphatic and aromatic hydrocarbons in the shale extracts primarily reflect the effects of thermal maturity rather than biodegradation. Overall, variations in the extent and patterns of biomarker biodegradation among coals and shales likely reflect their distinct microbial consortia that can be attributed to differences in (i) surviving microorganisms and inoculations from meteoric water, (ii) the characteristics of the sedimentary organic matter, especially the preponderance of aromatic constituents in coals, and (iii) the accessibility to that substrate through pores and cleats. These results help constrain the processes involved in biodegradation and controls on its extent, which, in turn, assist in recognizing sites favorable for methanogenesis and improved estimates of biogenic gas resources in the Illinois Basin.

Water-related Issues Affecting Conventional Oil and Gas Recovery and Potential Oil-Shale Development in the Uinta Basin, Utah  

SciTech Connect (OSTI)

Saline water disposal is one of the most pressing issues with regard to increasing petroleum and natural gas production in the Uinta Basin of northeastern Utah. Conventional oil fields in the basin provide 69 percent of Utah?s total crude oil production and 71 percent of Utah?s total natural gas, the latter of which has increased 208% in the past 10 years. Along with hydrocarbons, wells in the Uinta Basin produce significant quantities of saline water ? nearly 4 million barrels of saline water per month in Uintah County and nearly 2 million barrels per month in Duchesne County. As hydrocarbon production increases, so does saline water production, creating an increased need for economic and environmentally responsible disposal plans. Current water disposal wells are near capacity, and permitting for new wells is being delayed because of a lack of technical data regarding potential disposal aquifers and questions concerning contamination of freshwater sources. Many companies are reluctantly resorting to evaporation ponds as a short-term solution, but these ponds have limited capacity, are prone to leakage, and pose potential risks to birds and other wildlife. Many Uinta Basin operators claim that oil and natural gas production cannot reach its full potential until a suitable, long-term saline water disposal solution is determined. The enclosed project was divided into three parts: 1) re-mapping the base of the moderately saline aquifer in the Uinta Basin, 2) creating a detailed geologic characterization of the Birds Nest aquifer, a potential reservoir for large-scale saline water disposal, and 3) collecting and analyzing water samples from the eastern Uinta Basin to establish baseline water quality. Part 1: Regulators currently stipulate that produced saline water must be disposed of into aquifers that already contain moderately saline water (water that averages at least 10,000 mg/L total dissolved solids). The UGS has re-mapped the moderately saline water boundary in the subsurface of the Uinta Basin using a combination of water chemistry data collected from various sources and by analyzing geophysical well logs. By re-mapping the base of the moderately saline aquifer using more robust data and more sophisticated computer-based mapping techniques, regulators now have the information needed to more expeditiously grant water disposal permits while still protecting freshwater resources. Part 2: Eastern Uinta Basin gas producers have identified the Birds Nest aquifer, located in the Parachute Creek Member of the Green River Formation, as the most promising reservoir suitable for large-volume saline water disposal. This aquifer formed from the dissolution of saline minerals that left behind large open cavities and fractured rock. This new and complete understanding the aquifer?s areal extent, thickness, water chemistry, and relationship to Utah?s vast oil shale resource will help operators and regulators determine safe saline water disposal practices, directly impacting the success of increased hydrocarbon production in the region, while protecting potential future oil shale production. Part 3: In order to establish a baseline of water quality on lands identified by the U.S. Bureau of Land Management as having oil shale development potential in the southeastern Uinta Basin, the UGS collected biannual water samples over a three-year period from near-surface aquifers and surface sites. The near-surface and relatively shallow groundwater quality information will help in the development of environmentally sound water-management solutions for a possible future oil shale and oil sands industry and help assess the sensitivity of the alluvial and near-surface bedrock aquifers. This multifaceted study will provide a better understanding of the aquifers in Utah?s Uinta Basin, giving regulators the tools needed to protect precious freshwater resources while still allowing for increased hydrocarbon production.

Catalytic activity of oxidized (combusted) oil shale for removal of nitrogen oxides with ammonia as a reductant in combustion gas streams, Part 2  

SciTech Connect (OSTI)

Oxidized oil shale from the combustor in the LLNL Hot-Recycled-Solids (HRS) oil shale retorting process has been found to be a catalyst for removing nitrogen oxides from laboratory gas streams using NH{sub 3} as a reductant. Oxidized Green River oil shale heated at 10{degree}C/min in an Ar/O{sub 2}/NO/NH{sub 3} mixture ({approximately}93%/6%/2000 ppM/4000 ppM) with a gas residence time of {approximately}0.6 sec removed NO between 250 and 500{degree}C, with maximum removal of 70% at {approximately}400{degree}C. Under isothermal conditions with the same gas mixture, the maximum NO removal was {approximately}64%. When CO{sub 2} was added to the gas mixture at {approximately}8%, the NO removal dropped to {approximately}50%. However, increasing the gas residence time to {approximately}1.2 sec, increased NO removal to 63%. Nitrogen balances of these experiments suggest selective catalytic reduction of NO is occurring using NH{sub 3} as the reductant. These results are not based on completely optimized process conditions, but indicate oxidized oil shale is an effective catalyst for NO removal from combustion gas streams using NH{sub 3} as the reductant. Parameters calculated for implementing oxidized oil shale for NO{sub x} remediation on the current HRS retort indicate an abatement device is practical to construct.

Laboratory data in support of hydraulically fracturing EGSP OH Well No. 3. Final report  

SciTech Connect (OSTI)

Geologic and geophysical interpretations of data from the EGSP OH Well No. 3 show that an organically lean shale has a gradual transition with depth to an organically rich shale and that two layers (bound each shale formation. The laboratory test program was designed to understand the containment and productivity of a hydraulic fracture induced in this well to enhance gas production from the shale. The porosity in the formations of interest, including the upper barrier, the lower barrier, and the organic shales, varied from 6 to 10 percent. The porosity of each formation averaged about 8%. Densities and ultrasonic velocities were used to evaluate dynamic moduli. Over the tested intervals moduli consistently increased with depth. This indicates the possibility of upward migration of an induced fracture. Perforations, therefore, should be limited to the lower portion of the pay sand and it is also advisable to use low injection rates. Of the four fracturing fluids tested, the two code-named Dow II and Hal I caused, respectively, the least amount of matrix permeability damage to the organically lean and organically rich shales. However, the damage caused by the other fracturing fluids were not severe enough to cause any significant permanent reduction in well productivity. The fracture conductivity tests under the influence of fracturing fluids indicated that Hal I and Dow I caused, respectively, the least amount of multilayered fracture conductivity damage to the organically lean and organically rich samples. For monolayer fracture conductivities Dow I caused least damage to the organically lean shale. With the exception of Dow III all other fluids showed good results in the monolayer tests for organically rich shales. In the situation where both the lean and the rich shales are to be fractured together, the use of either Hal I or Dow I is indicated.

A combustion heater for oil shale heats particles of spent oil shale containing unburned char by burning the char. A delayed fall is produced by flowing the shale particles down through a stack of downwardly sloped overlapping baffles alternately extending from opposite sides of a vertical column. The delayed fall and flow reversal occurring in passing from each baffle to the next increase the residence time and increase the contact of the oil shale particles with combustion supporting gas flowed across the column to heat the shale to about 650 to 700/sup 0/C for use as a process heat source.

Oil shale technology  

SciTech Connect (OSTI)

Oil shale is undoubtedly an excellent energy source that has great abundance and world-wide distribution. Oil shale industries have seen ups and downs over more than 100 years, depending on the availability and price of conventional petroleum crudes. Market forces as well as environmental factors will greatly affect the interest in development of oil shale. Besides competing with conventional crude oil and natural gas, shale oil will have to compete favorably with coal-derived fuels for similar markets. Crude shale oil is obtained from oil shale by a relatively simple process called retorting. However, the process economics are greatly affected by the thermal efficiencies, the richness of shale, the mass transfer effectiveness, the conversion efficiency, the design of retort, the environmental post-treatment, etc. A great many process ideas and patents related to the oil shale pyrolysis have been developed; however, relatively few field and engineering data have been published. Due to the vast heterogeneity of oil shale and to the complexities of physicochemical process mechanisms, scientific or technological generalization of oil shale retorting is difficult to achieve. Dwindling supplied of worldwide petroleum reserves, as well as the unprecedented appetite of mankind for clean liquid fuel, has made the public concern for future energy market grow rapidly. the clean coal technology and the alternate fuel technology are currently of great significance not only to policy makers, but also to process and chemical researchers. In this book, efforts have been made to make a comprehensive text for the science and technology of oil shale utilization. Therefore, subjects dealing with the terminological definitions, geology and petrology, chemistry, characterization, process engineering, mathematical modeling, chemical reaction engineering, experimental methods, and statistical experimental design, etc. are covered in detail.

Fracture oil and gas reservoirs exist in large numbers. The accurate logging evaluation of fracture reservoirs has puzzled petroleum geologists for a long time. Nuclear magnetic resonance (NMR) logging is an effective new technology for borehole measurement and formation evaluation. It has been widely applied in non-fracture reservoirs, and good results have been obtained. But its application in fracture reservoirs has rarely been reported in the literature. This paper studies systematically the impact of fracture parameters (width, number, angle, etc), the instrument parameter (antenna length) and the borehole condition (type of drilling fluid) on NMR logging by establishing the equation of the NMR logging response in fracture reservoirs. First, the relationship between the transverse relaxation time of fluid-saturated fracture and fracture aperture in the condition of different transverse surface relaxation rates was analyzed; then, the impact of the fracture aperture, dip angle, length of two kinds of antennas and mud type was calculated through forward modeling and inversion. The results show that the existence of fractures affects the NMR logging; the characteristics of the NMR logging response become more obvious with increasing fracture aperture and number of fractures. It is also found that T2 distribution from the fracture reservoir will be affected by echo spacing, type of drilling fluids and length of antennas. A long echo spacing is more sensitive to the type of drilling fluid. A short antenna is more effective for identifying fractures. In addition, the impact of fracture dip angle on NMR logging is affected by the antenna length.

Integrated seismic study of naturally fractured tight gas reservoirs. Technical progress report, October 1, 1993--December 31, 1993  

SciTech Connect (OSTI)

This was the ninth quarter of the contract. During this quarter we (1) continued processing the seismic data, (2) collected additional logs to aid in the interpretation, and (3)began modeling some of the P-wave amplitude anomalies that we see in the data. The study area is located at the southern end of the powder river Basin in Converse county in east-central Wyoming. It is a low permeability fractured site, with both has and oil present. Reservoirs are highly compartmentalized due tot he low permeabilities, and fractures provide the only practical drainage paths for production. The two formations of interest are: The Niobrara; a fractured shale and limey shale to chalk, which is a reservoir rock, but also its own source rock. The Frontier, a tight sandstone lying directly below the Niobrara, brought into contract with it by an unconformity.

Failure of a gas well to respond to a foam hydraulic fracturing treatment  

SciTech Connect (OSTI)

Well No. 1 (not the real name of the well) is not producing gas at maximum capacity following a foam hydraulic fracturing treatment performed upon completion of the well in 1987. The failure of the stimulation treatment, which has affected other wells throughout the field, was due to a combination of three factors: (1) downward fracture growth and proppant settling during injection (2) embedment due to a high pressure drawdown in the wellbore during flowback procedures, and (3) poor cleanup of the fracture fluid due to high capillary pressures. The following are recommendations to help improve future fracturing treatments throughout the field: (1) Fracture at lower treating pressures; (2) Improve perforating techniques; (3) Change flowback procedures; and (4) Evaluate using N{sub 2} as a fracture fluid.

Coordinated study of the Devonian black shale in the Illinois Basin: Illinois, Indiana, and western Kentucky. Final report  

SciTech Connect (OSTI)

An evaluation of the resource potential of the Devonian shales, called the Eastern Gas Shales Project (EGSP) was begun. A study of the stratigraphy, structure, composition, and gas content of the Devonian shale in the Illinois Basin was undertaken by the State Geological Surveys of Illinois, Indiana, and Kentucky, under contract to the U.S. DOE as a part of the EGSP. Certain additional data were also developed by other research organizations (including Monsanto Research Corporation-Mound Facility and Battelle-Columbus Laboratory) on cores taken from the Illinois Basin. This report, an overview of geological data on the Illinois basin and interpretations of this data resulting from the EGSP, highlights areas of potential interest as exploration targets for possible natural gas resources in the Devonian shale of the basin. The information in this report was compiled during the EGSP from open file data available at the three State Geological surveys and from new data developed on cores taken by the DOE from the basin specifically for the EGSP. The organically richest shale is found in southeastern Illinois and in most of the Indiana and Kentucky portions of the Illinois Basin. The organic-rich shales in the New Albany are thickest near the center of the basin in southeastern Illinois, southwestern Indiana, and adjacent parts of Kentucky portions of the Illinois Basin. The organic-rich shales in the New Albany are thickest near the center of the basin in southeastern Illinois, southwestern Indiana, and adjacent parts of Kentucky. Natural fractures in the shale may aid in collecting gas from a large volume of shale. These fractures may be more abundant and interconnected to a greater degree in the vicinity of major faults. Major faults along the Rough Creek Lineament and Wabash Valley Fault System cross the deeper part of the basin.

Proposed natural gas protection program for Naval Oil Shale Reserves Nos. 1 and 3, Garfield County, Colorado  

SciTech Connect (OSTI)

As a result of US Department of Energy (DOE) monitoring activities, it was determined in 1983 that the potential existed for natural gas resources underlying the Naval Oil Shales Reserves Nos. 1 and 3 (NOSrs-1 3) to be drained by privately-owned gas wells that were being drilled along the Reserves borders. In 1985, DOE initiated a limited number of projects to protect the Government's interest in the gas resources by drilling its own offset production'' wells just inside the boundaries, and by formally sharing in the production, revenues and costs of private wells that are drilled near the boundaries ( communitize'' the privately-drilled wells). The scope of these protection efforts must be expanded. DOE is therefore proposing a Natural Gas Protection Program for NOSRs-1 3 which would be implemented over a five-year period that would encompass a total of 200 wells (including the wells drilled and/or communitized since 1985). Of these, 111 would be offset wells drilled by DOE on Government land inside the NOSRs' boundaries and would be owned either entirely by the Government or communitized with adjacent private land owners or lessees. The remainder would be wells drilled by private operators in an area one half-mile wide extending around the NOSRs boundaries and communitized with the Government. 23 refs., 2 figs., 6 tabs.

Oil shale retort apparatus  

DOE Patents [OSTI]

A retorting apparatus including a vertical kiln and a plurality of tubes for delivering rock to the top of the kiln and removal of processed rock from the bottom of the kiln so that the rock descends through the kiln as a moving bed. Distributors are provided for delivering gas to the kiln to effect heating of the rock and to disturb the rock particles during their descent. The distributors are constructed and disposed to deliver gas uniformly to the kiln and to withstand and overcome adverse conditions resulting from heat and from the descending rock. The rock delivery tubes are geometrically sized, spaced and positioned so as to deliver the shale uniformly into the kiln and form symmetrically disposed generally vertical paths, or "rock chimneys", through the descending shale which offer least resistance to upward flow of gas. When retorting oil shale, a delineated collection chamber near the top of the kiln collects gas and entrained oil mist rising through the kiln.

Analysis of Devonian shale multiwell interference tests in Meigs County, Ohio. Final report  

SciTech Connect (OSTI)

The Offset Well Test Program completed in 1981 was undertaken in order to investigate the production characteristics of Devonian shale reservoirs. The investigation involved a study of gas flow through natural fractures, the orientation and distribution of these fractures, and the gas storage/release mechanism and its effect on production. An experiment was designed to test the reservoir under strictly controlled conditions. Interference tests were conducted in Meigs County, Ohio on two wells drilled in the expected maximum and minimum permeability directions from a producing well with known completion and production history. Analysis of the test results indicate that the Devonian shale formation in the Meigs County, Ohio, area is an anisotropic, layered reservoir system. Flow characteristics indicate that the Meigs County reservoir is naturally fractured, may be represented as a dual porosity system, and may be modeled using pseudo-steady-state gas transfer from the matrix to the fracture system. The orientation of the natural fracture system was established through core observation and well test analysis as S65/sup 0/W. The maximum to minimum permeability ratio in the direction of the natural fracture system was calculated to be 8.3. Three distinct zones with independent flow characteristics were identified. The bottom zone, with permeability values significantly higher than the upper two zones, is highly fractured and is a major contributor to the gas production of Well 10056. The pressure profiles of the bottom zones relative to the upper zones were significantly different, indicating minimal communication between the layers. The knowledge of these parameters should have a significant impact on future development of shale reservoirs, through optimization of well spacing and choice of stimulation treatment to enhance gas production.

Natural and Induced Fracture Diagnostics from 4-D VSP in low Permeability Gas Reservoirs  

SciTech Connect (OSTI)

Tight gas sand reservoirs generally contain thick gas-charged intervals that often have low porosity and very low permeability. Natural and induced fractures provide the only means of production. The objective of this work is to locate and characterize natural and induced fractures from analysis of scattered waves recorded on 4-D (time lapse) VSP data in order to optimize well placement and well spacing in these gas reservoirs. Using model data simulating the scattering of seismic energy from hydraulic fractures, we first show that it is possible to characterize the quality of fracturing based upon the amount of scattering. In addition, the picked arrival times of recorded microseismic events provide the velocity moveout for isolating the scattered energy on the 4-D VSP data. This concept is applied to a field dataset from the Jonah Field in Wyoming to characterize the quality of the induced hydraulic fractures. The time lapse (4D) VSP data from this field are imaged using a migration algorithm that utilizes shot travel time tables derived from the first breaks of the 3D VSPs and receiver travel time tables based on the microseismic arrival times and a regional velocity model. Four azimuthally varying shot tables are derived from picks of the first breaks of over 200 VSP records. We create images of the fracture planes through two of the hydraulically fractured wells in the field. The scattered energy shows correlation with the locations of the microseismic events. In addition, the azimuthal scattering is different from the azimuthal reflectivity of the reservoir, giving us more confidence that we have separated the scattered signal from simple formation reflectivity. Variation of the scattered energy along the image planes suggests variability in the quality of the fractures in three distinct zones.

Geological controls and estimation algorithms of lacustrine shale gas adsorption capacity: A case study of the Triassic strata in the southeastern Ordos Basin, China  

Science Journals Connector (OSTI)

Abstract High-pressure methane adsorption experiments on a series of Triassic lacustrine shale moisture-equilibrated samples from the southeastern Ordos Basin, China, were conducted at pressure up to 20 MPa, two of which were measured at 30 °C, 40 °C, 50 °C, 60 °C, and 70 °C, and seven were performed under reservoir temperature (from 48 °C to 62 °C) to investigate the effect of organic matter content, maturity, mineralogical compositions and reservoir conditions (temperature and pressure) on the methane sorption capacity. The total organic carbon contents (TOCs) range from 0.91 wt.% to 6.11 wt.%. The thermal maturities, as inferred from Rock-Eval Analysis, range from low mature to high mature. The minerals of the shale samples are dominated by clays (36–57 wt.%) and quartz (19–44 wt.%). For the entire shale samples the dominant clay minerals are mixed-layer illite/smectite with some illite and no smectite exists, corresponding to a stage of late diagenesis. The studied samples have N2 BET surface areas ranging between 1.47 and 9.21 m2/g and pore volumes of 0.013–0.034 cm3/g. The methane sorption capacities of moisture-equilibrated shale samples show a positive correlation with TOC contents and BET surface areas. No relationship was observed between the clay contents and methane sorption capacities, indicating that clay minerals do not significantly contribute to methane sorption capacity in these organic shales. The Langmuir pressure (PL) increases exponentially with temperature and the Langmuir volume (VL) decreases linearly with temperature. A computational scheme has been developed to calculate the methane sorption capacity of shales as a function of TOC content, temperature and pressure based on Langmuir sorption isotherm function. Using this algorithm methane sorption capacity of organic shales as function of depth can be obtained. Due to the predominating effect of pressure the methane sorption capacity increases with depth initially, through a maximum and then decreases due to the influence of increasing temperature at a greater depth. The maximum gas sorption capacity typically occurs at a depth range between 400 and 900 m. With TOC content increasing, the maximum methane sorption capacities of organic shales and the corresponding depths increase.

Development of reservoir simulator for hydraulically fractured gas wells in noncontinuous lenticular reservoirs  

SciTech Connect (OSTI)

A mathematical model is presented which forms the basis for a reservoir simulator that can be used to assist in the interpretation and prediction of the performance of hydraulically fractured gas wells completed in the western tight sands area. The model represents a first step in developing a reservoir simulator that can be used as an exploration tool and to analyze proposed gas well tests and future production trends in noncontinuous sand lense formations which are representative of the tight gas sands located in the Rocky Mountain gas provinces. The model developed consists of the necessary mathematical equations to simulate both reservoir and well performance under a variety of operating conditions. The equations developed are general in that they consider the following effects: (1) three-dimensional flow in the reservoir and one-dimensional flow in the fracture; (2) non-Darcy flow in the reservoir and fracture; (3) wellbore and fracture storage; (4) formation damage on the fracture face; (5) frictional pressure drop in the production string; (6) noncontinuous sand lenses; and (7) Klinkenberg effect. As a start toward the development of the final version of the desired reservoir simulator, a two-dimensional simulator was secured, placed on the computer, and debugged, and some test cases were run to ensure its validity. Using this simulator as a starting point, changes to reflect the effects of items 3 and 6 were made since it was believed these were the more important effects to consider at this stage of development. The development of an operational two-dimensional gas reservoir simulator was completed. Further work will be required to extend the simulator to three dimensions and incorporate all the changes reflected in items 1 to 6.

Modeling and prediction of natural gas fracking pad landscapes in the Marcellus Shale region, USA. A rejoinder to Klein and Manda's commentary  

Science Journals Connector (OSTI)

Abstract In a comment on my early article (Meng, 2014) published in this journal, Klein and Manda (2015) critiqued some of my discussion points. Most significantly, they posited that “it is [therefore] erroneous to state that [in the Marcellus Shale region] land use characteristics are driving factors in well site/pad determination” because my speculation that “in the Marcellus Shale region the key variables for natural gas fracking can be landscape and environmental variables rather than geological variables” is flawed. In this rejoinder, I demonstrate that not only are their criticisms based on limited geological understanding of fracking, but they are also on an incorrect analysis. Therefore, my original results and conclusions on the driving force of landscape and environmental variables and on the implications to environment management and ecosystem administration and conservation remain stable and valid.

Effects of scale-up on oil and gas yields in a solid-recycle bed oil shale retorting process  

SciTech Connect (OSTI)

Fluidized bed pyrolysis of oil shale in a non-hydrogen atmosphere has been shown to significantly increase oil yield in laboratory-scale reactors compared to the Fischer assay by many workers. The enhancement in oil yield by this relatively simple and efficient thermal technique has led to the development of several oil shale retorting processes based on fluidized bed and related technologies over the past fifteen years. Since 1986, the Center for Applied Energy Research (CAER) has been developing one such process, KENTORT II, which is mainly tailored for the Devonian oil shales that occur in the eastern U.S. The process contains three main fluidized bed zones to pyrolyze, gasify, and combust the oil shale. A fourth fluidized bed zone serves to cool the spent shale prior to exiting the system. The autothermal process utilizes processed shale recirculation to transfer heat from the combustion to the gasification and pyrolysis zones. The CAER is currently testing the KENTORT II process in a 22.7-kg/hr process-development unit (PDU).

Eastern Gas Shales Project (EGSP) data files: a final report. Open-file report 81-598  

SciTech Connect (OSTI)

The United States Geological Survey and Petroleum Information Corporation (PI) of Denver have created two large computerized files of data for the Eastern Gas Shales Project (EGSP) as part of a large responsibility to the Department of Energy (DOE), Morgantown Energy Technology Center (METC), in Morgantown, West Virginia. Computer-compatible well, outdrop, and sample data from EGSP contractors are being stored on digital tape and delivered to METC for subsequent data-base management. This report has been written to: (1) discuss data-file background and development, (2) address specific problems and solutions for future project use, and (3) present a general summary of well- and sample-data file content by state, county, well, contractor, and subject coverage. When looking at the EGSP data-gathering task in retrospect, modifications to project management would have made the data-gathering process more successful. Many problems resulted from having contractors perform their own data encoding. Some EGSP contractors had little knowledge of computer- and data-encoding techniques, and they often delegated encoding responsibilities to subordinates who were not properly informed about procedures. The overall lack of uniformity in analytical procedures and methods resulted in an apparent over-abundance of card classes. Nearly 40% of the available card classes were never used, and about 30% of those used contain fewer than 100 data records. The most serious problem encountered during data-file development has been the long delay in arranging for an efficient retrieval and mapping system. Sample-and well-data file management are now coordinated through METC, and Petroleum Information Corporation maintains an effective in-house data management system for data retrieval and analysis. The present system would have been very useful to retrieve data for contractor needs two years earlier, even though the files were incomplete.
