Zero Discharge Water Management for Horizontal Shale Gas Well Development  

SciTech Connect

Hydraulic fracturing technology (fracking), coupled with horizontal drilling, has facilitated exploitation of huge natural gas (gas) reserves in the Devonian-age Marcellus Shale Formation (Marcellus) of the Appalachian Basin. The most-efficient technique for stimulating Marcellus gas production involves hydraulic fracturing (injection of a water-based fluid and sand mixture) along a horizontal well bore to create a series of hydraulic fractures in the Marcellus. The hydraulic fractures free the shale-trapped gas, allowing it to flow to the well bore where it is conveyed to pipelines for transport and distribution. The hydraulic fracturing process has two significant effects on the local environment. First, water withdrawals from local sources compete with the water requirements of ecosystems, domestic and recreational users, and/or agricultural and industrial uses. Second, when the injection phase is over, 10 to 30% of the injected water returns to the surface. This water consists of flowback, which occurs between the completion of fracturing and gas production, and produced water, which occurs during gas production. Collectively referred to as returned frac water (RFW), it is highly saline with varying amounts of organic contamination. It can be disposed of, either by injection into an approved underground injection well, or treated to remove contaminants so that the water meets the requirements of either surface release or recycle use. Depending on the characteristics of the RFW and the availability of satisfactory disposal alternatives, disposal can impose serious costs to the operator. In any case, large quantities of water must be transported to and from well locations, contributing to wear and tear on local roadways that were not designed to handle the heavy loads and increased traffic. The search for a way to mitigate the situation and improve the overall efficiency of shale gas production suggested a treatment method that would allow RFW to be used as make-up water for successive fracs. RFW, however, contains dissolved salts, suspended sediment and oils that may interfere with fracking fluids and/or clog fractures. This would lead to impaired well productivity. The major technical constraints to recycling RFW involves: identification of its composition, determination of industry standards for make-up water, and development of techniques to treat RFW to acceptable levels. If large scale RFW recycling becomes feasible, the industry will realize lower transportation and disposal costs, environmental conflicts, and risks of interruption in well development schedules.

Study of Flow Regimes in Multiply-Fractured Horizontal Wells in Tight Gas and Shale Gas Reservoir Systems  

E-Print Network (OSTI)

Various analytical, semi-analytical, and empirical models have been proposed to characterize rate and pressure behavior as a function of time in tight/shale gas systems featuring a horizontal well with multiple hydraulic fractures. Despite a small number of analytical models and published numerical studies there is currently little consensus regarding the large-scale flow behavior over time in such systems. The purpose of this work is to construct a fit-for-purpose numerical simulator which will account for a variety of production features pertinent to these systems, and to use this model to study the effects of various parameters on flow behavior. Specific features examined in this work include hydraulically fractured horizontal wells, multiple porosity and permeability fields, desorption, and micro-scale flow effects. The theoretical basis of the model is described in Chapter I, along with a validation of the model. We employ the numerical simulator to examine various tight gas and shale gas systems and to illustrate and define the various flow regimes which progressively occur over time. We visualize the flow regimes using both specialized plots of rate and pressure functions, as well as high-resolution maps of pressure distributions. The results of this study are described in Chapter II. We use pressure maps to illustrate the initial linear flow into the hydraulic fractures in a tight gas system, transitioning to compound formation linear flow, and then into elliptical flow. We show that flow behavior is dominated by the fracture configuration due to the extremely low permeability of shale. We also explore the possible effect of microscale flow effects on gas effective permeability and subsequent gas species fractionation. We examine the interaction of sorptive diffusion and Knudsen diffusion. We show that microscale porous media can result in a compositional shift in produced gas concentration without the presence of adsorbed gas. The development and implementation of the micro-flow model is documented in Chapter III. This work expands our understanding of flow behavior in tight gas and shale gas systems, where such an understanding may ultimately be used to estimate reservoir properties and reserves in these types of reservoirs.

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.

It Seems Like Shale Gas Came Out It Seems Like Shale Gas Came Out of Nowhere - What Happened? Knowledge of gas shale resources and even production techniques has been around a long time (see "Technological Highlights" timeline). But even as recently as a few years ago, very little of the resource was considered economical to produce. Innovative advances - especially in horizontal drilling, hydraulic fracturing and other well stimulation technologies - did much to make hundreds of trillions of cubic feet of shale gas technically recoverable where it once was not. The U.S. Department of Energy's (DOE) Office of Fossil Energy, along with industry partners, was heavily involved in the innovation chain, and helped to make some of these techniques, as well as protective

General screening criteria for shale gas reservoirs and production data analysis of Barnett shale  

E-Print Network (OSTI)

Shale gas reservoirs are gaining importance in United States as conventional oil and gas resources are dwindling at a very fast pace. The purpose of this study is twofold. First aim is to help operators with simple screening criteria which can help them in making certain decisions while going after shale gas reservoirs. A guideline chart has been created with the help of available literature published so far on different shale gas basins across the US. For evaluating potential of a productive shale gas play, one has to be able to answer the following questions: 1. What are the parameters affecting the decision to drill a horizontal well or a vertical well in shale gas reservoirs? 2. Will the shale gas well flow naturally or is an artificial lift required post stimulation? 3. What are the considerations for stimulation treatment design in shale gas reservoirs? A comprehensive analysis is presented about different properties of shale gas reservoirs and how these properties can affect the completion decisions. A decision chart presents which decision best answers the above mentioned questions. Secondly, research focuses on production data analysis of Barnett Shale Gas reservoir. The purpose of this study is to better understand production mechanisms in Barnett shale. Barnett Shale core producing region is chosen for the study as it best represents behavior of Barnett Shale. A field wide moving domain analysis is performed over Wise, Denton and Tarrant County wells for understanding decline behavior of the field. It is found that in all of these three counties, Barnett shale field wells could be said to have established pressure communication within the reservoir. We have also studied the effect of thermal maturity (Ro %), thickness, horizontal well completion and vertical well completion on production of Barnett Shale wells. Thermal maturity is found to have more importance than thickness of shale. Areas with more thermal maturity and less shale thickness are performing better than areas with less thermal maturity and more shale thickness. An interactive tool is developed to access the production data according to the leases in the region and some suggestions are made regarding the selection of the sample for future studies on Barnett Shale.

Site selection, drilling, and completion of two horizontal wells in the Devonian Shales of West Virginia  

Science Conference Proceedings (OSTI)

This report presents a summary of the geologic site selection studies, planning, drilling, completing, stimulating, and testing of two horizontal wells drilled in the Devonian Shales of the Appalachian Basin in West Virginia. Each horizontal well was designed and managed by BDM as the prime contractor to the Department of Energy. The first well was drilled with industry partner Cabot Oil and Gas Corporation in Putnam County, West Virginia. The second well was drilled with Consolidated Natural Gas Company in Calhoun County, West Virginia. This report summarizes four reports prepared by BDM which detail the site selection rationale and the drilling and completion operations of each well. Each horizontal well is currently producing commercial quantities of hydrocarbons. The successful application of horizontal well technology represent continued development of the technology for application to tight and unconventional natural gas resources of the United States. Continued technology development is expected to ultimately result in commercial horizontal well drilling activity by industry in the Appalachian Basin.

NATURAL GAS FROM SHALE: Questions and Answers  

Energy.gov (U.S. Department of Energy (DOE)) Indexed Site

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.

Enriching off gas from oil shale retort  

SciTech Connect

Liquid and gaseous products are recovered from oil shale in an in situ oil shale retort in which a combustion zone is advanced therethrough by a method which includes the steps of establishing a combustion zone in the oil shale in the in situ oil shale retort and introducing a gaseous feed mixture into the combustion zone in the direction the combustion zone is to be advanced through the in situ oil shale retort. The gaseous feed mixture comprises an oxygen supplying gas and water vapor and is introduced into the combustion zone at a rate sufficient to maintain the temperature in the combustion zone within a predetermined range of temperatures above the retorting temperature of the oil shale in the in situ oil shale retort and sufficient to advance the combustion zone through the in situ oil shale retort. The introduction of the gaseous feed mixture into the combustion zone generates combustion products gases which together with the portion of the gaseous feed mixture which does not take part in the combustion process, is called flue gas. The flue gas passes through the oil shale on the advancing side of the combustion zone, thereby retorting the oil shale to produce liquid and gaseous products. The liquid product and the retort off gas, which comprises gaseous product and flue gas, are withdrawn from the in situ oil shale retort at a point on the advancing side of the retorting zone. 47 claims, 1 figure.

Process Design and Integration of Shale Gas to Methanol  

E-Print Network (OSTI)

Recent breakthroughs in horizontal drilling and hydraulic fracturing technology have made huge reservoirs of previously untapped shale gas and shale oil formations available for use. These new resources have already made a significant impact on the United States chemical industry and present many opportunities for new capital investments and industry growth. As in conventional natural gas, shale gas contains primarily methane, but some formations contain significant amounts of higher molecular weight hydrocarbons and inorganic gases such as nitrogen and carbon dioxide. These differences present several technical challenges to incorporating shale gas with current infrastructure designed to be used with natural gas. However, each shale presents opportunities to develop novel chemical processes that optimize its composition in order to more efficiently and profitably produce valuable chemical products. This paper is aimed at process synthesis, analysis, and integration of different processing pathways for the production of methanol from shale gas. The composition of the shale gas feedstock is assumed to come from the Barnett Shale Play located near Fort Worth, Texas, which is currently the most active shale gas play in the US. Process simulation and published data were used to construct a base-case scenario in Aspen Plus. The impact of different processing pathways was analyzed. Key performance indicators were assessed. These include overall process targets for mass and energy, economic performance, and environmental impact. Finally, the impact of several factors (e.g., feedstock composition, design and operating variables) is studied through a sensitivity analysis. The results show a profitable process above a methanol selling price of approximately $1.50/gal. The sensitivity analysis shows that the ROI depends much more heavily on the selling price of methanol than on the operating costs. Energy integration leads to a savings of $30.1 million per year, or an increase in ROI of 2% points. This also helps offset some of the cost required for the oxygen necessary for syngas generation through partial oxidation. For a sample shale gas composition with high levels of impurities, preprocessing costs require a price differential of $0.73/MMBtu from natural gas. The process is also environmentally desirable because shale gas does not lead to higher GHG emissions than conventional natural gas. More water is required for hydraulic fracturing, but some of these concerns can be abated through conservation techniques and regulation.

Material balance assay of Devonian gas shale  

DOE Green Energy (OSTI)

A Devonian shale retorting method, similar to the TOSCO Material Balance Assay, was developed. Oil, gas, water, and spent shale collected from the thermal decomposition of Devonian shale provide material balance closure. Elemental and other analyses were used to characterize the products and evaluate their fuel potential. The precision of each analysis was estimated by running a series of material balance assays on a composite shale sample. The elemental composition of this shale oil was shown to remain unchanged on aging. Typical material balance assays from each well where core samples were taken are presented.

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  

Science Conference Proceedings (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.

Each horizontal well was designed and managed by BDM as the prime contractor to the Department of Energy. The first well was drilled with industry partner Cabot Oil and Gas Corporation in Putnam County, West Virginia. The second well was drilled with Consolidated Natural Gas Company in Calhoun County, West Virginia. This report summarizes four reports prepared by BDM which detail the site selection rationale and the drilling and completion operations of each well. Each horizontal well is currently producing commercial quantities of hydrocarbons. The successful application of horizontal well technology represent continued development of the technology for application to tight and unconventional natural gas resources of the United States. Continued technology development is expected to ultimately result in commercial horizontal well drilling activity by industry in the Appalachian Basin.

NATURAL GAS FROM SHALE: Questions and Answers  

Energy.gov (U.S. Department of Energy (DOE)) Indexed Site

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

Life-cycle analysis of shale gas and natural gas.  

SciTech Connect

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

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.

Horizontal Devonian shale well, Columbia Natural Resources, Inc.`s, Pocohontas Development Corp. Well 21747, Martin County, Kentucky. Final report  

SciTech Connect

Columbia Gas and the United States Department of Energy (DOE) have successfully completed field work on a horizontally drilled Devonian shale well located in Martin County, Kentucky. The objective of this cofunded project is to assess the effectiveness and economic feasibility of applying horizontal drilling and hydraulically fracturing stimulation techniques to enhance the extraction of natural gas from the Devonian shale. The well is comprised of three segments: a conventional vertical section, an angle build section and a horizontal section. The well reached a measured depth (MD) of 6263 feet, 3810 feet true vertical depth (TVD), with a horizontal displacement of 2812 feet achieved in the desired direction of N10{degrees}W. Both air and foam were used as drilling fluids. The vertical, lateral and tangent sections were drilled using conventional rotary drilling methods. Downhole motors were used to build angle. A total combined final open flow of 3.1 MMcfd was measured from all zones. Total well expenditures are approximately $1,460,000. Of this amount, $700,000 is directly related to the research and learning curve experience aspects.

Horizontal Devonian shale well, Columbia Natural Resources, Inc. 's, Pocohontas Development Corp. Well 21747, Martin County, Kentucky  

SciTech Connect

Columbia Gas and the United States Department of Energy (DOE) have successfully completed field work on a horizontally drilled Devonian shale well located in Martin County, Kentucky. The objective of this cofunded project is to assess the effectiveness and economic feasibility of applying horizontal drilling and hydraulically fracturing stimulation techniques to enhance the extraction of natural gas from the Devonian shale. The well is comprised of three segments: a conventional vertical section, an angle build section and a horizontal section. The well reached a measured depth (MD) of 6263 feet, 3810 feet true vertical depth (TVD), with a horizontal displacement of 2812 feet achieved in the desired direction of N10{degrees}W. Both air and foam were used as drilling fluids. The vertical, lateral and tangent sections were drilled using conventional rotary drilling methods. Downhole motors were used to build angle. A total combined final open flow of 3.1 MMcfd was measured from all zones. Total well expenditures are approximately $1,460,000. Of this amount, $700,000 is directly related to the research and learning curve experience aspects. It is projected that the same horizontal well could be drilled with existing technology for $700,000. If advanced can be made in MWD systems for air drilling environments, wells of this type could be drilled routinely for $500,000. It appears that application of horizontal drilling will result in at least acceleration of gas production and possibly the addition of recoverable reserves from the Devonian shale. Production data, necessary to validate this statement, are also required to determine the economics.

Water management practices used by Fayetteville shale gas producers.  

SciTech Connect

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.

Production Trends of Shale Gas Wells  

E-Print Network (OSTI)

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

High-precision core analysis has been performed on eight Devonian gas shale samples from the Appalachian basin. Seven of the core samples consist of the Upper Devonian Age Huron member of the Ohio shale, six of which came from wells in the Ohio River valley, and the seventh from a well in east-central Kentucky. The eight core sample consists of Middle Devonian Age Marcellus shale obtained from a well in Morgantown, WV. The core analysis was originally intended to supply accurate input data for Devonian shale numerical reservoir simulation. Unexpectedly, the work has identified a number of geological factors that influence gas production from organic-rich shales. The presence of petroleum as a mobile liquid phase in the pores of all seven Huron shale samples effectively limits the gas porosity of this formation to less than 0.2%, and gas permeability of the rock matrix is commonly less than 0.1 ..mu..d at reservoir stress. The Marcellus shale core, on the other hand, was free of a mobile liquid phase and had a measured gas porosity of approximately 10%, and a surprisingly high permeability of 20 ..mu..d. Gas permeability of the Marcellus was highly stress-dependent, however; doubling the net confining stress reduced the permeability by nearly 70%. The conclusion reached from this study is that the gas productivity potential of Devonian shale in the Appalachian basin is influenced by a wide range of geologic factors. Organic content, thermal maturity, natural fracture spacing, and stratigraphic relationships between gray and black shales all affect gas content and mobility. Understanding these factors can improve the exploration and development of Devonian shale gas.

Method for forming an in situ oil shale retort with horizontal free faces  

DOE Patents (OSTI)

A method for forming a fragmented permeable mass of formation particles in an in situ oil shale retort is provided. A horizontally extending void is excavated in unfragmented formation containing oil shale and a zone of unfragmented formation is left adjacent the void. An array of explosive charges is formed in the zone of unfragmented formation. The array of explosive charges comprises rows of central explosive charges surrounded by a band of outer explosive charges which are adjacent side boundaries of the retort being formed. The powder factor of each outer explosive charge is made about equal to the powder factor of each central explosive charge. The explosive charges are detonated for explosively expanding the zone of unfragmented formation toward the void for forming the fragmented permeable mass of formation particles having a reasonably uniformly distributed void fraction in the in situ oil shale retort.

The Antrim Shale: Structural and stratigraphic influences on gas production  

Science Conference Proceedings (OSTI)

The Antrim Shale of the Michigan basin is one of the most actively drilled gas plays in the United States. Core analysis, geologic mapping, and core to log correlations of a 9 mi{sup 2} study area in the middle of the present play have defined geologic influences on the location and productivity of Antrim reservoirs. Application of these factors in the design of exploration and development strategies could improve gas recovery from the Antrim Shale. The lower section of the Antrim Shale, containing the present producing horizons, is composed of four lithologies that subdivide the Antrim into facies and parasequences based upon their mineralogy and textural characteristics. The black shales of the producing horizons are characterized by high but variable quartz contents and an extremely fine-grained matrix of muscovite and clays. The black shales are surrounded by two types of gray shale, differentiated by amount and form of carbonates, and a green shale. The type of shale bounding the productive, organic-rich black shales may affect stimulation strategies and their effectiveness. These black shales average 10% but can be as high as 20% TOC by weight. The organic contents impart a distinctive signature to gamma ray logs that enabled isopach, lithofacies, and structural mapping of the Antrim. Correlated with available production data, the maps reveal distinct trends suggesting that well performance is influenced by both structural and stratigraphic controls.

forecasts are independent of approval by any other officer or employee of the United States Government. The views in this report therefore should not be construed as representing those of the Department of Energy or other Federal agencies. Background The use of horizontal drilling in conjunction with hydraulic fracturing has greatly expanded the ability of producers to profitably produce natural gas from low permeability geologic formations, particularly shale formations. Application of fracturing techniques to stimulate oil and gas production began to grow rapidly in the 1950s, although experimentation dates back to the 19 th century. Starting in the mid-1970s, a partnership of private operators, the U.S. Department of Energy (DOE) and the Gas Research Institute (GRI) endeavored to develop technologies for the commercial production of natural gas from the relatively shallow Devonian (Huron) shale in the Eastern United States. This partnership helped foster technologies that eventually became crucial to producing natural gas from shale rock, including horizontal wells, multi-stage fracturing, and slick-water fracturing. 1 Practical application of horizontal drilling to oil production began in the early 1980s, by which time the advent of improved downhole drilling motors and the invention of other necessary supporting equipment, materials, and technologies, particularly downhole telemetry equipment, had brought some applications within the realm of

New basins invigorate U.S. gas shales play  

SciTech Connect

While actually the first and oldest of unconventional gas plays, gas shales have lagged the other main unconventional gas resources--tight gas and coalbed methane--in production and proved reserves. Recently, however, with active drilling of the Antrim shales in Michigan and promising results from the Barnett shales of North Texas, this gas play is growing in importance. While once thought of as only an Appalachian basin Devonian-age Ohio shales play and the exclusive domain of regional independents, development of gas shales has expanded to new basins and has began to attract larger E and P firms. Companies such as Amoco, Chevron, and Shell in the Michigan basin and Mitchell Energy and Development and Anadarko Petroleum Corporation in the Fort Worth basin are aggressively pursuing this gas resource. This report, the third of a four part series assessing unconventional gas development in the US, examines the state of the gas shales industry following the 1992 expiration of the Sec. 29 Nonconventional Fuels Tax Credit. The main questions being addressed are first, to what extent are these gas sources viable without the tax credit, and second, what advances in understanding of these reservoirs and what progress in extraction technologies have changed the outlook for this large but complex gas resource?

Technically recoverable Devonian shale gas in West Virginia  

Science Conference Proceedings (OSTI)

This report evaluates the natural gas potential of the Devonian Age shales of West Virginia. For this, the study: (1) compiles the latest geological 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 (Huron, Rhinestreet, and Marcellus intervals) in West Virginia is estimated to range from 11 to 44 trillion cubic feet. (2) The Devonian shales in this state entail great geological diversity; the highly fractured, permeable shales in the southwest respond well to traditional development practices while the deep, tight shales in the eastern and northern parts of the state will require new, larger scale well stimulation technology. (3) Beyond the currently developed Huron and Rhinestreet shale intervals, the Marcellus shale offers a third attractive gas zone, particularly in the north central portion of the state. 21 references, 53 figures, 27 tables.

Simulating the Effect of Water on the Fracture System of Shale Gas Wells  

E-Print Network (OSTI)

It was observed that many hydraulically fractured horizontal shale gas wells exhibit transient linear flow behavior. A half-slope on a type curve represents this transient linear flow behavior. Shale gas wells show a significant skin effect which is uncommon in tight gas wells and masks early time linear behavior. Usually 70-85 percent of frac water is lost in the formation after the hydraulic fracturing job. In this research, a shale gas well was studied and simulated post hydraulic fracturing was modeled to relate the effect of frac water to the early significant skin effect observed in shale gas wells. The hydraulically fractured horizontal shale gas well was described in this work by a linear dual porosity model. The reservoir in this study consisted of a bounded rectangular reservoir with slab matrix blocks draining into neighboring hydraulic fractures and then the hydraulic fractures feed into the horizontal well that fully penetrates the entire rectangular reservoir. Numerical and analytical solutions were acquired before building a 3D 19x19x10 simulation model to verify accuracy. Many tests were conducted on the 3D model to match field water production since initial gas production was matching the analytical solutions before building the 3D simulation model. While some of the scenarios tested were artificial, they were conducted in order to reach a better conceptual understanding of the field. Increasing the water saturation in the formation resulted in increasing water production while lowering gas production. Adding a fractured bottom water layer that leaked into the hydraulic fracture allowed the model to have a good match of water and gas production rates. Modeling trapped frac water around the fracture produced approximately the same amount of water produced by field data, but the gas production was lower. Totally surrounding the fracture with frac water blocked all gas production until some of the water was produced and gas was able to pass through. Finally, trapped frac water around the fracture as combined with bottom water showed the best results match. It was shown that frac water could invade the formation surrounding the hydraulic fracture and could cause formation damage by blocking gas flow. It was also demonstrated that frac water could partially block off gas flow from the reservoir to the wellbore and thus lower the efficiency of the hydraulic fracturing job. It was also demonstrated that frac water affects the square root of time plot. It was proven by simulation that the huge skin at early time could be caused by frac water that invades and gets trapped near the hydraulic fractures due to capillary pressure.

Porosity and permeability of eastern Devonian gas shale  

Science Conference Proceedings (OSTI)

High-precision core analysis has been performed on eight samples of Devonian gas shale from the Appalachian Basin. Seven of the core samples consist of the Upper Devonian age Huron Member of the Ohio Shale, six of which came from wells in the Ohio River valley, and the seventh from a well in east-central Kentucky. The eighth core sample consists of Middle Devonian age Marcellus Shale obtained from a well in Morgantown, West Virginia. The core analysis was originally intended to supply accurate input data for Devonian shale numerical reservoir simulation. Unexpectedly, the results have also shown that there are a number of previously unknown factors which influence or control gas production from organic-rich shales of the Appalachian Basin. The presence of petroleum as a mobile liquid phase in the pores of all seven Huron Shale samples effectively limits the gas porosity of this formation to less than 0.2%, and permeability of the rock matrix to gas is less than 0.1 microdarcy at reservoir stress. The Marcellus Shale core, on the other hand, was free of a mobile liquid phase and had a measured gas porosity of approximately 10% under stress with a fairly strong ''adsorption'' component. Permeability to gas (K/sub infinity/ was highly stress-dependent, ranging from about 20 microdarcies at a net stress of 3000 psi down to about 5 microdarcies at a net stress of 6000 psi. The conclusion reached from this study is that Devonian shale in the Appalachian Basin is a considerably more complex natural gas resource than previously thought. Production potential varies widely with geographic location and stratigraphy, just as it does with other gas and oil resources. 15 refs., 8 figs., 3 tabs.

Fracture Fluids Fracture Fluids Key Points: * Shale fracture fluid, or "slickwater," is largely composed of water (99%); but a number of additives are mixed in with it to increase the effectiveness of the fracturing operation. These additives vary as a function of the well type and the preferences of the operator. * Hydraulic fracturing fluids can contain hazardous chemicals and, if mismanaged, spills could leak harmful substances into ground or surface water. However, good field practice, governed by existing regulations, "should provide an adequate level of protection" from fracturing fluid risks. 1 1 Massachusetts Institute of Technology, "MIT Study on the Future of Natural Gas," June 6, 2011, Chapter 2: Supply, page 41.

Method for explosive expansion toward horizontal free faces for forming an in situ oil shale retort  

DOE Patents (OSTI)

Formation is excavated from within a retort site in formation containing oil shale for forming a plurality of vertically spaced apart voids extending horizontally across different levels of the retort site, leaving a separate zone of unfragmented formation between each pair of adjacent voids. Explosive is placed in each zone, and such explosive is detonated in a single round for forming an in situ retort containing a fragmented permeable mass of formation particles containing oil shale. The same amount of formation is explosively expanded upwardly and downwardly toward each void. A horizontal void excavated at a production level has a smaller horizontal cross-sectional area than a void excavated at a lower level of the retort site immediately above the production level void. Explosive in a first group of vertical blast holes is detonated for explosively expanding formation downwardly toward the lower void, and explosive in a second group of vertical blast holes is detonated in the same round for explosively expanding formation upwardly toward the lower void and downwardly toward the production level void for forming a generally T-shaped bottom of the fragmented mass.

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.

Various models featuring horizontal wells with multiple induced fractures have been proposed to characterize flow behavior over time in tight gas and shale gas systems. Currently, there is little consensus regarding the effects of non-ideal fracture geometries and coupled primary-secondary fracture interactions on reservoir performance in these unconventional gas reservoirs. This thesis provides a grid construction tool to generate high-resolution unstructured meshes using Voronoi grids, which provides the flexibility required to accurately represent complex geologic domains and fractures in three dimensions. Using these Voronoi grids, the interaction between propped hydraulic fractures and secondary "stress-release" fractures were evaluated. Additionally, various primary fracture configurations were examined, where the fractures may be non-planar or non-orthogonal. For this study, a numerical model was developed to assess the potential performance of tight gas and shale gas reservoirs. These simulations utilized up to a half-million grid-blocks and consider a period of up to 3,000 years in some cases. The aim is to provide very high-definition reference numerical solutions that will exhibit virtually all flow regimes we can expect in these unconventional gas reservoirs. The simulation results are analyzed to identify production signatures and flow regimes using diagnostic plots, and these interpretations are confirmed using pressure maps where useful. The coupled primary-secondary fracture systems with the largest fracture surface areas are shown to give the highest production in the traditional "linear flow" regime (which occurs for very high conductivity vertical fracture cases). The non-ideal hydraulic fracture geometries are shown to yield progressively lower production as the angularity of these fractures increases. Hence, to design optimum fracture completions, we should endeavor to keep the fractures as orthogonal to the horizontal well as possible. This work expands the current understanding of flow behavior in fractured tight-gas and shale-gas systems and may be used to optimize fracture and completion design, to validate analytical models and to facilitate more accurate reserves estimation.

Gas collection system for oil shale retort  

SciTech Connect

An in-situ oil shale retorting process is described in which a cavity filled with broken particles of oil shale is formed within the subsurface oil shale formation and air is forced down through the cavity to sustain combustion of the top layer of oil shale particles, the products of combustion being withdrawn at the bottom of the cavity. A plurality of exhaust pipes traverse the bottom of the cavity and extend out through the sealed entrance to the retort cavity. The pipes are supported above the floor of the cavity and have holes opening on the bottom side of the pipes through which the product gases are withdrawn from the cavity. Valves in each pipe control the flow so as to balance the flow distribution of air and exhaust gases through the retorting cavity.

NETL: News Release - DOE's Early Investment in Shale Gas Technology  

NLE Websites -- All DOE Office Websites (Extended Search)

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.

Eastern Gas Shales Project outgassing analysis. Special report  

SciTech Connect

Two methods are used on the Eastern Gas Shales Project to measure the gas volume of encapsulated shale samples. The direct method measures pressure and volume and is initiated almost immediately upon encapsulation of the sample. A second method measures pressure, volume, and composition, and is initiated after pressure is allowed to build up over several weeks. A combination of the two methods has been used on selected samples, and yields more data as it allows extrapolation to account for gas lost prior to encapsulation. The stratigraphic horizons, characterized by dark shales with high organic and high carbon content and a relatively high gamma ray intensity of 200+ API units also have high gas contents (relative to other units within the same well). The Lower Huron, Rhinestreet, and Marcellus Shales are high in gas content relative to other stratigraphic units at the same sites. The difference in gas content of the same stratigraphic horizon between well sites appears to be controlled by the thermal maturity. Kinetic studies have shown that, in some samples, significant amounts of gas are released after the time when the gas volume would be initially measured. Additional work needs to be performed to determine why the rates and volume of gas released vary between samples.

Evaluation of the eastern gas shales in Pennsylvania  

Science Conference Proceedings (OSTI)

To evaluate the potential of the Devonian shale as a source of natural gas, the US Department of Energy (DOE) has undertaken the Eastern Gas Shales Project (EGSP). The EGSP is designed not only to identify the resource, but also to test improved methods of inducing permeability to facilitate gas drainage, collection, and production. The ultimate goal of this project is to increase the production of gas from the eastern shales through advanced exploration and exploitation techniques. The purpose of this report is to inform the general public and interested oil and gas operators about EGSP results as they pertain to the Devonian gas shales of the Appalachian basin in Pennsylvania. Geologic data and interpretations are summarized and areas where the accumulation of gas may be large enough to justify commercial production are outlined. Because the data presented in this report are generalized and not suitable for evaluation of specific sites for exploration, the reader should consult the various reports cited for more detail and discussion of the data, concepts, and interpretations presented.

A Technical and Economic Study of Completion Techniques In Five Emerging U.S. Gas Shale Plays  

E-Print Network (OSTI)

methane and other higher order hydrocarbons, through C4, with interest in further developing reactions important to methane- and ethane-related chemistry. With the increased demand for energy and the declining conventional hydrocarbons worldwide, energy companies, both majors and independents, are turning to unconventional resources to produce the hydrocarbons required to meet market demand. From coalbed methane to low permeability (tight) gas reservoirs and gas shales, energy companies are making substantial progress in developing the technologies required to bring these unconventional reserves to the market. A common misconception is that there are not enough domestic oil and gas reserves to fuel our economy. The United States imports most of the oil used for transportation fuel and several TCF of natural gas annually. However, there is a very large resource of natural gas in unconventional reservoirs, with over 2,200 TCF of gas in place in just the gas shale formations that have been identified in the energy arena (Navigant Study 2008). There are still major gas shale plays and basins that have not been explored and are waiting to be evaluated and developed. The natural gas in shales and other unconventional reservoirs can be used to generate electricity, or it can be turned into liquids and used by the transportation industry. It is also misconstrued that gas shales are relatively new in our industry and something of the future. The first commercially viable gas shale well was drilled in the early 1920s in Pennsylvania, before the famous oil well drilled by Colonel Drake. The objectives of this study are to (1) complete literature review to establish which geologic parameters affect completion techniques in five emerging gas shales: the Antrium, the Barnett, the Haynesville, the Marcellus, and the Woodford; (2) identify the different completion methods; (3) create an economic model for the completion techniques discussed; (4) develop a sensitivity analysis on various economic parameters to determine optimal completion strategy; and (5) create completion flowcharts. Based on the literature review I have done for several gas shale basins, I have identified seven pertinent geologic parameters that influence completion practices. These are depositional environment, total organic content (TOC), average gas content, shale mineralogy, shale thickness, and reservoir pressure. Next, I identified different completion and simulation trends in the industry for the different shale plays. The results from this study show that although there are some stark differences between depths (i.e. the Antrim Shale and the Haynesville Shale), shale plays are very similar in all other geologic properties. Interestingly, even with a large range for the different geological parameters, the completion methods did not drastically differ indicating that even if the properties do not fall within the range presented in this paper does not automatically rule them out for further evaluation in other plays. In addition to the evaluation of geologic properties, this study looked at drilling cost and the production profile for each play. Due to the volatility of the energy industry, economic sensitivity was completed on the price, capital, and operating cost to see what affect it would have on the play. From the analysis done, it is concluded that horizontal drilling in almost any economic environment is economic except for one scenario for the Woodford Shale. Therefore, gas shales plays should still be invested in even in lower price environments and companies should try to take advantage of the lower cost environments that occur during these times. With continual development of new drilling and completion techniques, these plays will become more competitive and can light the path for exploration of new shale plays worldwide.

Pressure Transient Analysis and Production Analysis for New Albany Shale Gas Wells  

E-Print Network (OSTI)

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

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

DOE Green Energy (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.

Synthesis of organic geochemical data from the Eastern Gas Shales  

Science Conference Proceedings (OSTI)

Over 2400 core and cuttings samples of Upper Devonian shales from wells in the Appalachian, Illinois, and Michigan Basins have been characterized by organic geochemical methods to provide a basis for accelerating the exploitation of this unconventional, gas-rich resource. This work was part of a program initiated to provide industry with criteria for locating the best areas for future drilling and for the development of stimulation methods that will make recovery of the resource economically attractive. The geochemical assessment shows that the shale, in much of the Appalachian, Illinois, and Michigan Basins is source rock that is capable of generating enormous quantities of gas. In some areas the shales are also capable of generating large quantities of oil as well. The limiting factors preventing these sources from realizing most of their potential are their very low permeabilities and the paucity of potential reservoir rocks. This geochemical data synthesis gives direction to future selection of sites for stimulation research projects in the Appalachian Basin by pinpointing those areas where the greatest volumes of gas are contained in the shale matrix. Another accomplishment of the geochemical data synthesis is a new estimate of the total resource of the Appalachian Basin. The new estimate of 2500 TCF is 25 percent greater than the highest previous estimates. This gives greater incentive to government and industry to continue the search for improved stimulation methods, as well as for improved methods for locating the sites where those improved stimulation methods can be most effectively applied.

We then drove into the field to some of SEECO's properties to see first-hand what the well sites looked like. In 2006, the U.S. Department of Energy's (DOE's) National Energy Technology Laboratory (NETL) made several funding awards under a program called Low Impact Natural Gas and Oil (LINGO). One of the projects that received an award is 'Probabilistic Risk-Based Decision Support for Oil and Gas Exploration and Production Facilities in Sensitive Ecosystems'. The University of Arkansas at Fayetteville has the lead on the project, and Argonne National Laboratory is a partner. The goal of the project is to develop a Web-based decision support tool that will be used by mid- and small-sized oil and gas companies as well as environmental regulators and other stakeholders to proactively minimize adverse ecosystem impacts associated with the recovery of gas reserves in sensitive areas. The project focuses on a large new natural gas field called the Fayetteville Shale. Part of the project involves learning how the natural gas operators do business in the area and the technologies they employ. The field trip on August 9 provided an opportunity to do that.

The Implications and Flow Behavior of the Hydraulically Fractured Wells in Shale Gas Formation  

E-Print Network (OSTI)

Shale gas formations are known to have low permeability. This low permeability can be as low as 100 nano darcies. Without stimulating wells drilled in the shale gas formations, it is hard to produce them at an economic rate. One of the stimulating approaches is by drilling horizontal wells and hydraulically fracturing the formation. Once the formation is fractured, different flow patterns will occur. The dominant flow regime observed in the shale gas formation is the linear flow or the transient drainage from the formation matrix toward the hydraulic fracture. This flow could extend up to years of production and it can be identified by half slop on the log-log plot of the gas rate against time. It could be utilized to evaluate the hydraulic fracture surface area and eventually evaluate the effectiveness of the completion job. Different models from the literature can be used to evaluate the completion job. One of the models used in this work assumes a rectangular reservoir with a slab shaped matrix between each two hydraulic fractures. From this model, there are at least five flow regions and the two regions discussed are the Region 2 in which bilinear flow occurs as a result of simultaneous drainage form the matrix and hydraulic fracture. The other is Region 4 which results from transient matrix drainage which could extend up to many years. The Barnett shale production data will be utilized throughout this work to show sample of the calculations. This first part of this work will evaluate the field data used in this study following a systematic procedure explained in Chapter III. This part reviews the historical production, reservoir and fluid data and well completion records available for the wells being analyzed. It will also check for data correlations from the data available and explain abnormal flow behaviors that might occur utilizing the field production data. It will explain why some wells might not fit into each model. This will be followed by a preliminary diagnosis, in which flow regimes will be identified, unclear data will be filtered, and interference and liquid loading data will be pointed. After completing the data evaluation, this work will evaluate and compare the different methods available in the literature in order to decide which method will best fit to analyze the production data from the Barnett shale. Formation properties and the original gas in place will be evaluated and compared for different methods.

Adsorption studies of natural gas storage in Devonian shales  

SciTech Connect

Significant amounts of natural gas exist as an adsorbed, or condensed, phase in Devonian shale formations and other unconventional gas resources. The amount of the adsorbed phase depends on the pressure and temperature. The Langmuir isotherm has been used to describe the pressure dependence. However, temperature dependence has not been explored. This is important to evaluate thermal simulation as a recovery method and to extrapolate laboratory measurements to reservoir conditions. The authors investigate adsorption as a function of both pressure and temperature. They found that the effects of temperature are significant and that the Langmuir model does not describe adsorption adequately. They reconciled the data with bi-Langmuir models.

Shale gas in the southern central area of New York State: Part I. How to find and develop shale gas in New York State  

SciTech Connect

The Appalachian Basin contains vast volumes of shale gas, and a significant potion of this is contained in three shales in south-central New York - the Rhinestreet, the Geneseo and the Marcellus. The economics of shale-gas exploration in New York are not very attractive to the large oil and gas companies, which seek a rapid return on their investments. The situation may be quite different for organizations which are more concerned with security of supply and stability of cost; these may include manufacturing companies, colleges, hospitals, state institutions and industrial or agricultural cooperatives. For these, production of even a modest 50 Mcf/day/well, declining slowly over many years, would be appealing if it could be guaranteed. To date three wells have been artificially fractured in the Marcellus shale of New York, and all three appear to be producers. This is only a small sample, and one of the wells is known to have encountered natural fractures. However, it does raise the possbility that (while nothing in exploration can be truly guaranteed) the chances of extracting at least some gas from the Marcellus - using modern fracturing techniques - are good. The chances are improved if geological techniques can identify zones of a suitable degree of natural fracturing in the shale. These techniques are aided by detailed structure maps of the shale units; such a map has been prepared for the Geneseo shale, as part of this project. The present conclusion is that the most likely source of shale gas in south-central New York is the Marcellus formation. Shale-gas wells should be drilled with air. The dry open hole should be logged with gamma-ray, density, temperature and noise logs. The shale should be artificially fractured using a nitrogen stimulation technique. Recommendations are given for each of these steps in the text.

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

Science Conference Proceedings (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.

Investigation of the Geokinetics horizontal in situ oil shale retorting process. Quarterly report, January-March 1980  

DOE Green Energy (OSTI)

Retort No. 18 produced 3479 barrels of oil during the quarter for a total of 4528 barrels to date. Chromatographic analyses of Retort No. 18 shale oil by the GKI analytical laboratory indicated variation in the oil from the wells near the air-in end and from the air-out end of the retort. Shale oil has been blended with Altamont crude (the Roosevelt refinery's normal feedstock); the distillation, API gravity, pour point, flash point, Naptha and Cat Gas were not affected by the shale oil. The diesel off the crude unit changed from water white to yellow, however, and a fine grayish-brown precipitate formed. Re-entry drilling was performed on Retorts No. 21, No. 22, and No. 23 during the quarter; tracer tests were run by Sandia Laboratories on Retorts No. 19, No. 21, No. 22, and No. 23. Blasthole drilling began on Retort No. 25.

Effect of shale-water recharge on brine and gas recovery from geopressured reservoirs  

DOE Green Energy (OSTI)

The concept of shale-water recharge has often been discussed and preliminary assessments of its significance in the recovery of geopressured fluids have been given previously. The present study uses the Pleasant Bayou Reservoir data as a base case and varies the shale formation properties to investigate their impact on brine and gas recovery. The parametric calculations, based on semi-analytic solutions and finite-difference techniques, show that for vertical shale permeabilities which are at least of the order of 10/sup -5/ md, shale recharge will constitute an important reservoir drive mechanism and will result in much larger fluid recovery than that possible in the absence of shale dewatering.

Geological controls on natural gas production in the Antrim Shale of the Michigan basin  

Science Conference Proceedings (OSTI)

The Antrim Shale (Devonian-Mississippian) is a prolific natural gas reservoir with distinctive source rock and reservoir characteristics. The Antrim is composed of two distinctive lithofacies: a black shale lithofacies having total organic carbon (TOC) values as high as 12% and a gray-green shale lithofacies having TOC values generally below 0.5 %. The black shale facies is the primary source bed and reservoir for natural gas. Based on Rock-Eval data the kerogen in the Antrim Shale is only marginally mature with respect to generation of liquid hydrocarbons. This in the range of 435{degree}C, vitrinite reflectance values are 0.41, and thermal alteration index (TAI) is 2. These data indicate a maximum burial temperature of approximately 60{degree}C in Otsego County, Michigan, the main play area. Although the thermal maturation level in this area is very low, the gas produced from the Antrim is internally sourced and thermogenic; this interpretation is based on the presence of trace amounts of high-gravity oil and a thermogenic isotopic signature of produced gas samples. The black shale facies in the Antrim contains significant authigenic silica and is more susceptible to fracturing compared to the carbonate-cemented gray-green shales facies. Extremely low gas permeability values (0.1 md) indicates that fractures serve as conduits for delivery of gas to the borehole. Most of the gas must be stored in the shale matrix porosity because total gas volume produced far exceeds fracture reservoir volume.

Study of gas evolution during oil shale pyrolysis by TQMS (triple quadrupole mass spectrometer)  

DOE Green Energy (OSTI)

Real-time gas evolution during pyrolysis of two Green River Formation (Colorado) oil shales, one eastern US Devonian shale, and two Chinese shales was monitored using a triple quadrupole mass spectrometer (TQMS). We calculated kinetic parameters for hydrocarbon generation. For water, carbon oxides, and sulfur gases, we compared evolution profiles and identified the organicinorganic precursors of each species. We also monitored nitrogen- and sulfur-containing naphtha components. Hydrocarbon gas profiles, except for CH/sub 4/, are similar for all shales, and their rates of evolution reach a maximum at around the temperatures of maximum oil evolutions. The evolution profiles for H/sub 2/, CH/sub 2/, CO, and CO/sub 2/, at high temperatures are affected by the amount of char remaining in shale, carbonate minerals, and the water-gas shift reaction. The water profile, in general, consists of waters from surface dehydration, kerogen pyrolysis, and mineral dehydration. Mineral dehydration was the dominant water source for all shales, but the temperature ranges for the major water peak varied because of widely different mineral composition. Chinese shales evolved much more water than U.S. shales. Major differences between shales were seen in the sulfur gases. 17 refs., 4 figs., 3 tabs.

The Antrim shale, fractured gas reservoirs with immense potential  

Science Conference Proceedings (OSTI)

Antrim shale gas production has grown from 0.4 Bcf of gas in 1987 to 127 Bcf in 1994, causing record gas production in Michigan. Recent industry activity suggests the play will continue to expand. The GRI Hydrocarbon Model's Antrim resource base description was developed in 1991 based on industry activity through 1990. The 1991 description estimated 32 Tcf of recoverable resource, and was limited to northern Michigan which represents only part of the Antrim's total potential. This description indicated production could increase manyfold, even with low prices. However, its well recovery rate is less than current industry results and projected near term production lags actual production by 1 to 2 years. GRI is updating its description to better reflect current industry results and incorporate all prospective areas. The description in northern Michigan is updated using production and well data through 1994 and results from GRI's research program. The description is then expanded to the entire basin. Results indicate the northern resource is somewhat larger than the previous estimate and the wells perform better. Extrapolation to the entire basin using a geologic analog model approximately doubles the 1991 estimate. The model considers depositional, structural, and tectonic influences; fracturing; organic content; thermal history; and hydrocarbon generation, migration and storage. Pleistocene glaciation and biogenic gas are also included for areas near the Antrim subcrop.

A New Method for History Matching and Forecasting Shale Gas/Oil Reservoir Production Performance with Dual and Triple Porosity Models  

E-Print Network (OSTI)

Different methods have been proposed for history matching production of shale gas/oil wells which are drilled horizontally and usually hydraulically fractured with multiple stages. These methods are simulation, analytical models, and empirical equations. It has been well known that among the methods listed above, analytical models are more favorable in application to field data for two reasons. First, analytical solutions are faster than simulation, and second, they are more rigorous than empirical equations. Production behavior of horizontally drilled shale gas/oil wells has never been completely matched with the models which are described in this thesis. For shale gas wells, correction due to adsorption is explained with derived equations. The algorithm which is used for history matching and forecasting is explained in detail with a computer program as an implementation of it that is written in Excel's VBA. As an objective of this research, robust method is presented with a computer program which is applied to field data. The method presented in this thesis is applied to analyze the production performance of gas wells from Barnett, Woodford, and Fayetteville shales. It is shown that the method works well to understand reservoir description and predict future performance of shale gas wells. Moreover, synthetic shale oil well also was used to validate application of the method to oil wells. Given the huge unconventional resource potential and increasing energy demand in the world, the method described in this thesis will be the "game changing" technology to understand the reservoir properties and make future predictions in short period of time.

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.

Shale gas in the southern central area of New York State: Part II. Experience of locating and drilling four shale-gas wells in New York State  

Science Conference Proceedings (OSTI)

Four shale-gas wells have been located and drilled in the south-central area of New York State as part of this project. The four wells that were drilled are: the Rathbone well, in Steuben County, was located on the north side of a graben, in an old shale-gas field; it penetrated the Rhinestreet, Geneseo and Marcellus shales. Artificial stimulation was performed in the Rhinestreet, without marked success, and in the Marcellus; the latter formation has a calculated open flow of 110 Mcf/day and appears capable of initial production of 100 Mcf/day against a back-pressure of 500 psi. The Dansville well, in Livingston County, tested the Geneseo and Marcellus shales at shallower depth. Artificial stimulation was performed in the Marcellus. The calculated open flow is 95 Mcf/day, and the well appears capable of initial production of 70 Mcf/day against a back-pressure of 300 psi. The Erwin and N. Corning wells, both near Corning in Steuben County, were designed to test the possibility of collecting gas from a fractured conduit layer connecting to other fracture systems in the Rhinestreet shale. The N. Corning well failed; the expected conduit was found to be only slightly fractured. The Erwin well encountered a good initial show of gas at the conduit, but the gas flow was not maintained; even after artificial stimulation the production is only 10 Mcf/day. The present conclusion is that the most likely source of shale gas in south-central New York is the Marcellus shale formation. Important factors not yet established are the decline rate of Marcellus production and the potential of the Geneseo after stimulation.

SciTech Connect

Disclosed is a process for removing acidic impurities from off-gases generated in the retorting of oil shale comprising contacting a rubblized mass of oil shale which has been substantially depleted in hydrocarbonaceous materials with water, so as to extract basic components from the mass; and contacting off-gases, which were generated during the retorting of oil shale and which contain acidic impurities, with the water containing basic components so as to substantially remove said acidic impurities from the off-gases. Also disclosed is a process for the in situ retorting of oil shale and removal of acidic impurities from off-gases generated in the in situ or surface retorting of oil shale comprising forming a plurality of subterranean in situ oil shale retorts containing rubblized oil shale having a void space of about 5 to about 40 per cent; retorting a first subterranean in situ retort until the rubblized oil shale is spent and substantially depleted in hydrocarbonaceous material; injecting water into the spent retort so as to deplete the heat content of the retorted rubblized oil shale and to form steam; recovering and using the steam in the retorting of a second subterranean in situ oil shale retort; continuing to inject water into the spent first retort so as to extract basic components from the retorted rubblized oil shale; recovering the water containing basic components; and contacting off-gases generated during the in situ or surface retorting of oil shale, the off-gases containing acidic impurities, with the water containing basic components so as to substantially remove acidic impurities from the off-gases.

Optimization of fractured well performance of horizontal gas wells  

E-Print Network (OSTI)

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

Horizontal Well Placement Optimization in Gas Reservoirs Using Genetic Algorithms  

E-Print Network (OSTI)

Horizontal well placement determination within a reservoir is a significant and difficult step in the reservoir development process. Determining the optimal well location is a complex problem involving many factors including geological considerations, reservoir and fluid properties, economic costs, lateral direction, and technical ability. The most thorough approach to this problem is that of an exhaustive search, in which a simulation is run for every conceivable well position in the reservoir. Although thorough and accurate, this approach is typically not used in real world applications due to the time constraints from the excessive number of simulations. This project suggests the use of a genetic algorithm applied to the horizontal well placement problem in a gas reservoir to reduce the required number of simulations. This research aims to first determine if well placement optimization is even necessary in a gas reservoir, and if so, to determine the benefit of optimization. Performance of the genetic algorithm was analyzed through five different case scenarios, one involving a vertical well and four involving horizontal wells. The genetic algorithm approach is used to evaluate the effect of well placement in heterogeneous and anisotropic reservoirs on reservoir recovery. The wells are constrained by surface gas rate and bottom-hole pressure for each case. This project's main new contribution is its application of using genetic algorithms to study the effect of well placement optimization in gas reservoirs. Two fundamental questions have been answered in this research. First, does well placement in a gas reservoir affect the reservoir performance? If so, what is an efficient method to find the optimal well location based on reservoir performance? The research provides evidence that well placement optimization is an important criterion during the reservoir development phase of a horizontal-well project in gas reservoirs, but it is less significant to vertical wells in a homogeneous reservoir. It is also shown that genetic algorithms are an extremely efficient and robust tool to find the optimal location.

Investigation of the geokinetics horizontal in situ oil shale retorting process. Quarterly report, April, May, June 1980  

DOE Green Energy (OSTI)

The Retort No. 18 burn was terminated on May 11, 1980. A total of 5547 barrels of shale oil or 46 percent of in-place resource was recovered from the retort. The EPA-DOE/LETC post-burn core sampling program is underway on Retort No. 16. Eleven core holes (of 18 planned) have been completed to date. Preliminary results indicate excellent core recovery has been achieved. Recovery of 702 ft of core was accomplished. The Prevention of Significant Deterioration (PSD) permit application was submitted to the EPA regional office in Denver for review by EPA and Utah air quality officials. The application for an Underground Injection Control (UIC) permit to authorize GKI to inject retort wastewater into the Mesa Verde Formation is being processed by the State of Utah. A hearing before the Board of Oil, Gas and Mining is scheduled in Salt Lake City, Utah, for July 22, 1980. Re-entry drilling on Retort No. 24 is progressing and placement of surface equipment is underway. Retort No. 25 blasthole drilling was completed and blast preparations are ongoing. Retort No. 25 will be blasted on July 18, 1980. The retort will be similar to Retort No. 24, with improvements in blasthole loading and detonation. US Patent No. 4,205,610 was assigned to GKI for a shale oil recovery process. Rocky Mountain Energy Company (RME) is evaluating oil shale holdings in Wyoming for application of the GKI process there.

Sedimentology of gas-bearing Devonian shales of the Appalachian Basin  

SciTech Connect

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.

Accounting for Adsorbed gas and its effect on production bahavior of Shale Gas Reservoirs  

E-Print Network (OSTI)

Shale gas reservoirs 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 reservoirs comes from desorption. Ignoring a major component of production, such as desorption, could result in significant errors in analysis of these wells. Therefore it is important to understand the adsorption phenomenon and to include its effect in order to avoid erroneous analysis. The objective of this work was to imbed the adsorbed gas in the techniques used previously for the analysis of tight gas reservoirs. Most of the desorption from shale gas reservoirs takes place in later time when there is considerable depletion of free gas and the well is undergoing boundary dominated flow (BDF). For that matter BDF methods, to estimate original gas in place (OGIP), that are presented in previous literature are reviewed to include adsorbed gas in them. More over end of the transient time data can also be used to estimate OGIP. Kings modified z* and Bumb and McKee’s adsorption compressibility factor for adsorbed gas are used in this work to include adsorption in the BDF and end of transient time methods. Employing a mass balance, including adsorbed gas, and the productivity index equation for BDF, a procedure is presented to analyze the decline trend when adsorbed gas is included. This procedure was programmed in EXCEL VBA named as shale gas PSS with adsorption (SGPA). SGPA is used for field data analysis to show the contribution of adsorbed gas during the life of the well and to apply the BDF methods to estimate OGIP with and without adsorbed gas. The estimated OGIP’s were than used to forecast future performance of wells with and without adsorption. OGIP estimation methods when applied on field data from selected wells showed that inclusion of adsorbed gas resulted in approximately 30 percent increase in OGIP estimates and 17 percent decrease in recovery factor (RF) estimates. This work also demonstrates that including adsorbed gas results in approximately 5percent less stimulated reservoir volume estimate.

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

E-Print Network (OSTI)

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

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.

Science Conference Proceedings (OSTI)

The Gas Research Institute (GRI) Eastern Gas Data System is an interactive information resource developed to provide ready access to substantive data on wells producing from the Devonian shales. The system is a computerized database which contains descriptive and historical geological and engineering data on a large number of Devonian shale gas wells in the Appalachian Basin. The principal purpose of the system is to meet the requirements for technical data of gas producers, researchers and GRI. The data is provided by cooperating industry sources, many of whom were also instrumental in the original definition and design of the system. The information which has been collected and compiled on individual wells includes data on identification, location, elevation, drilling, geology, cementing, perforation, stimulation, cleanup, and production histories. The Eastern Gas Data System currently contains extensive information on over 620 Devonian shale gas wells completed in the Appalachian Basin.

Data Bias in Rate Transient Analysis of Shale Gas Wells  

E-Print Network (OSTI)

Superposition time functions offer one of the effective ways of handling variable-rate data. However, they can also be biased and misleading the engineer to the wrong diagnosis and eventually to the wrong analysis. Since the superposition time functions involve rate as essential constituent, the superposition time is affected greatly with rate issues. Production data of shale gas wells are usually subjected to operating issues that yield noise and outliers. Whenever the rate data is noisy or contains outliers, it will be hard to distinguish their effects from common regime if the superposition time functions are used as plotting time function on log-log plots. Such deceiving presence of these flow regimes will define erroneous well and reservoir parameters. Based on these results and with the upsurge of energy needs there might be some costly decisions will be taken such as refracting or re-stimulating the well especially in tight formations. In this work, a simple technique is presented in order to rapidly check whether there is data bias on the superposition-time specialized plots or not. The technique is based on evaluating the kernel of the superposition time function of each flow regime for the maximum production time. Whatever beyond the Kernel-Equivalent Maximum Production Time (KEMPT) it is considered as biased data. The hypothesis of this technique is that there is no way to see in the reservoir more than what has been seen. A workflow involving different diagnostic and filtering techniques has been proposed to verify proposed notion. Different synthetic and field examples were used in this study. Once the all problematic issues have been detected and filtered out, it was clear that whatever went beyond the KEMPT is a consequence of these issues. Thus, the proposed KEMPT technique can be relied on in order to detect and filter out the biased data points on superposition-time log-log plots. Both raw and filtered data were analyzed using type-curve matching of linear flow type-curves for calculating the original gas in-place (OGIP). It has been found that biased data yield noticeable reduced OGIP. Such reduction is attributed to the early fictitious onset of boundary dominated flow, where early false detection of the drainage boundaries defines less gas in-place occupied in these boundaries.

INTEGRATION OF HIGH TEMPERATURE GAS REACTORS WITH IN SITU OIL SHALE RETORTING  

Science Conference Proceedings (OSTI)

This paper evaluates the integration of a high-temperature gas-cooled reactor (HTGR) to an in situ oil shale retort operation producing 7950 m3/D (50,000 bbl/day). The large amount of heat required to pyrolyze the oil shale and produce oil would typically be provided by combustion of fossil fuels, but can also be delivered by an HTGR. Two cases were considered: a base case which includes no nuclear integration, and an HTGR-integrated case.

Shale gas in the southern central area of New York State. Volume III. Experience of drilling five shale-gas wells in New York State  

SciTech Connect

Five shale-gas wells have been located and drilled in the South-Central areas of New York State as part of this program. The program was undertaken by Arlington Exploration Company (AEC) during 1981 and 1982. The wells were drilled on educational properties in an attempt to demonstrate the economic prospect of natural gas for institutional and small commercial consumers to develop their own source of energy. All five wells were completed in the Marcellus section of the Devonian shale. Each of the five wells was connected to an appropriate heat load for the purpose of production testing. The project supports the theory that a well drilled anywhere in South-Central New York and completed in the Marcellus Shale using modern fracturing techniques (i.e. nitrogen foam) is likely to produce some gas. Important factors not yet predictable are the decline rate of Marcellus production and the volume of recoverable reserves. Depths to the Marcellus Shale generally increase from north (i.e. Houghton College) to south (i.e. Portville Central School).

Determining the locus of a processing zone in an oil shale retort by effluent off gas heating value  

SciTech Connect

A processing zone advances through a fragmented permeable mass of particles containing oil shale in an in situ oil shale retort in a subterranean formation containing oil shale. The retort has an effluent gas passing therefrom. The effluent gas has a heating value which is dependent on the kerogen content of the oil shale then in contact with the processing zone. To determine the locus of the processing zone, the formation is assayed at selected locations in the retort for kerogen content before processing the selected locations, and effluent gas from the retort is monitored for its heating value.

Exploration-production studies in newly drilled Devonian-Shale gas wells. Annual report, February 1, 1985-January 31, 1986  

SciTech Connect

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

Occurrence of oil and gas in Devonian shales and equivalents in West Virginia  

SciTech Connect

During the Devonian, an epicontinental sea was present in the Appalachian basin. The Catskill Clastic Wedge was formed in the eastern part of the basin by sediments derived from land along the margin of the continent. Three facies are recognized in the Catskill Clastic Wedge: (1) a red-bed facies deposited in terrestrial and nearshore marine environments; (2) a gray shale and sandstone facies deposited in a shallow- to moderately-deep marine environment; and (3) a dark-gray shale and siltstone facies deposited in the deepest part of the epicontinental sea. Oil and natural gas are being produced from Devonian shales in the western part of West Virginia and from upper Devonian sandstones and siltstones in the north-central part of the state. It is suggested that in addition to extending known areas of gas production, that drilling for natural gas be conducted in areas underlain by organic-rich shales and thick zones of interbedded siltstone and shale in the Devonian section in central, southern, and western West Virginia. The most promising areas for exploration are those areas where fractures are associated with folds, faults, and lineaments. 60 references.

Evidence of Pressure Dependent Permeability in Long-Term Shale Gas Production and Pressure Transient Responses  

E-Print Network (OSTI)

The current state of shale gas reservoir dynamics demands understanding long-term production, and existing models that address important parameters like fracture half-length, permeability, and stimulated shale volume assume constant permeability. Petroleum geologists suggest that observed steep declining rates may involve pressure-dependent permeability (PDP). This study accounts for PDP in three potential shale media: the shale matrix, the existing natural fractures, and the created hydraulic fractures. Sensitivity studies comparing expected long-term rate and pressure production behavior with and without PDP show that these two are distinct when presented as a sequence of coupled build-up rate-normalized pressure (BU-RNP) and its logarithmic derivative, making PDP a recognizable trend. Pressure and rate field data demonstrate evidence of PDP only in Horn River and Haynesville but not in Fayetteville shale. While the presence of PDP did not seem to impact the long term recovery forecast, it is possible to determine whether the observed behavior relates to change in hydraulic fracture conductivity or to change in fracture network permeability. As well, it provides insight on whether apparent fracture networks relate to an existing natural fracture network in the shale or to a fracture network induced during hydraulic fracturing.

Gas sales starting from Indiana`s fractured New Albany shale  

Science Conference Proceedings (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.

Using Decline Curve Analysis, Volumetric Analysis, and Bayesian Methodology to Quantify Uncertainty in Shale Gas Reserve Estimates  

E-Print Network (OSTI)

Probabilistic decline curve analysis (PDCA) methods have been developed to quantify uncertainty in production forecasts and reserves estimates. However, the application of PDCA in shale gas reservoirs is relatively new. Limited work has been done on the performance of PDCA methods when the available production data are limited. In addition, PDCA methods have often been coupled with Arp’s equations, which might not be the optimum decline curve analysis model (DCA) to use, as new DCA models for shale reservoirs have been developed. Also, decline curve methods are based on production data only and do not by themselves incorporate other types of information, such as volumetric data. My research objective was to integrate volumetric information with PDCA methods and DCA models to reliably quantify the uncertainty in production forecasts from hydraulically fractured horizontal shale gas wells, regardless of the stage of depletion. In this work, hindcasts of multiple DCA models coupled to different probabilistic methods were performed to determine the reliability of the probabilistic DCA methods. In a hindcast, only a portion of the historical data is matched; predictions are made for the remainder of the historical period and compared to the actual historical production. Most of the DCA models were well calibrated visually when used with an appropriate probabilistic method, regardless of the amount of production data available to match. Volumetric assessments, used as prior information, were incorporated to further enhance the calibration of production forecasts and reserves estimates when using the Markov Chain Monte Carlo (MCMC) as the PDCA method and the logistic growth DCA model. The proposed combination of the MCMC PDCA method, the logistic growth DCA model, and use of volumetric data provides an integrated procedure to reliably quantify the uncertainty in production forecasts and reserves estimates in shale gas reservoirs. Reliable quantification of uncertainty should yield more reliable expected values of reserves estimates, as well as more reliable assessment of upside and downside potential. This can be particularly valuable early in the development of a play, because decisions regarding continued development are based to a large degree on production forecasts and reserves estimates for early wells in the play.

Release of gas from heated oil shale and from mixtures of dolomite and quartz  

DOE Green Energy (OSTI)

Experiments and calculations were performed to determine the amount of gas released from heated oil shale. It is known that kerogen, a component of oil shale, releases gas when heated. When the temperature is increased, the kerogen yields not only gas but char, a solid that reacts with steam and CO/sub 2/ (by-products of heated shale) to yield H/sub 2/ and CO. It was found that as much as 200 moles of CO and H/sub 2/ could be produced by the reaction of 1 kg of kerogen with steam at 1200/sup 0/C. Another of the gas-releasing components of oil shale, carbonate minerals, begins to decompose at 500/sup 0/C; decomposition is complete at about 700/sup 0/C after 1000 hr. The minerals begin to decompose at a lower temperature in steam. Reactions among carbonates and silicates resulted in the release of CO/sub 2/ even under high CO/sub 2/ pressure.

Horizontal underbalanced drilling of gas wells with coiled tubing  

Science Conference Proceedings (OSTI)

Coiled tubing drilling technology is gaining popularity and momentum as a significant and reliable method of drilling horizontal underbalanced wells. It is quickly moving into new frontiers. To this point, most efforts in the Western Canadian Basin have been focused towards sweet oil reservoirs in the 900--1300 m true vertical depth (TVD) range, however there is an ever-increasing interest in deeper and gas-producing formations. Significant design challenges on both conventional and coiled tubing drilling operations are imposed when attempting to drill these formations underbalanced. Coiled tubing is an ideal technology for underbalanced drilling due to its absence of drillstring connections resulting in continuous underbalanced capabilities. This also makes it suitable for sour well drilling and live well intervention without the risk of surface releases of reservoir gas. Through the use of pressure deployment procedures it is possible to complete the drilling operation without need to kill the well, thereby maintaining underbalanced conditions right through to the production phase. The use of coiled tubing also provides a means for continuous wireline communication with downhole steering, logging and pressure recording devices.

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

Science Conference Proceedings (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.

Applications for a high temperature gas cooled nuclear reactor in oil shale processing  

SciTech Connect

Results are presented of a study concerning possible applications for a high temperature gas cooled reactor as a process heat source in oil shale retorting and upgrading. Both surface and in situ technologies were evaluated with respect to the applicability and potential benefits of introducing an outside heat source. The primary focus of the study was to determine the fossil resource which might be conserved, or freed for higher uses than furnishing process heat. In addition to evaluating single technologies, a centralized upgrading plant, which would hydrotreat the product from a 400,000 bbl/day regional shale oil industry was also evaluated. The process heat required for hydrogen manufacture via steam reforming, and for whole shale oil hydrotreating would be supplied by an HTGR. Process heat would be supplied where applicable, and electrical power would be generated for the entire industry.

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

Science Conference Proceedings (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 (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.

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 (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.

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.

A Novel Approach For the Simulation of Multiple Flow Mechanisms and Porosities in Shale Gas Reservoirs  

E-Print Network (OSTI)

The state of the art of modeling fluid flow in shale gas reservoirs is dominated by dual porosity models that divide the reservoirs into matrix blocks that significantly contribute to fluid storage and fracture networks which principally control flow capacity. However, recent extensive microscopic studies reveal that there exist massive micro- and nano- pore systems in shale matrices. Because of this, the actual flow mechanisms in shale reservoirs are considerably more complex than can be simulated by the conventional dual porosity models and Darcy’s Law. Therefore, a model capturing multiple pore scales and flow can provide a better understanding of complex flow mechanisms occurring in these reservoirs. Through the use of a unique simulator, this research work establishes a micro-scale multiple-porosity model for fluid flow in shale reservoirs by capturing the dynamics occurring in three separate porosity systems: organic matter (mainly kerogen); inorganic matter; and natural fractures. Inorganic and organic portions of shale matrix are treated as sub-blocks with different attributes, such as wettability and pore structures. In the organic matter or kerogen, gas desorption and diffusion are the dominant physics. Since the flow regimes are sensitive to pore size, the effects of smaller pores (mainly nanopores and picopores) and larger pores (mainly micropores and nanopores) in kerogen are incorporated in the simulator. The separate inorganic sub-blocks mainly contribute to the ability to better model dynamic water behavior. The multiple porosity model is built upon a unique tool for simulating general multiple porosity systems in which several porosity systems may be tied to each other through arbitrary transfer functions and connectivities. This new model will allow us to better understand complex flow mechanisms and in turn to extend simulation to the reservoir scale including hydraulic fractures through upscaling techniques

Stimulation rationale for shale gas wells: a state-of-the-art report  

Science Conference Proceedings (OSTI)

Despite the large quantities of gas contained in the Devonian Shales, only a small percentage can be produced commercially by current production methods. This limited production derives both from the unique reservoir properties of the Devonian Shales and the lack of stimulation technologies specifically designed for a shale reservoir. Since October 1978 Science Applications, Inc. has been conducting a review and evaluation of various shale well stimulation techniques with the objective of defining a rationale for selecting certain treatments given certain reservoir conditions. Although this review and evaluation is ongoing and much more data will be required before a definitive rationale can be presented, the studies to date do allow for many preliminary observations and recommendations. For the hydraulic type treatments the use of low-residual-fluid treatments is highly recommended. The excellent shale well production which is frequently observed with only moderate wellbore enlargement treatments indicates that attempts to extend fractures to greater distances with massive hydraulic treatments are not warranted. Immediate research efforts should be concentrated upon limiting production damage by fracturing fluids retained in the formation, and upon improving proppant transport and placement so as to maximize fracture conductivity. Recent laboratory, numerical modeling and field studies all indicate that the gas fracturing effects of explosive/propellant type treatments are the predominate production enhancement mechanism and that these effects can be controlled and optimized with properly designed charges. Future research efforts should be focused upon the understanding, prediction and control of wellbore fracturing with tailored-pulse-loading charges. 36 references, 7 figures, 2 tables.

Summary: What is the issue? Several studies have projected large positive economic impacts of shale gas development in the Marcellus region. To make informed choices for their communities, policy makers need to understand the strengths and limitations of these studies. Most importantly, they need to understand that there is a tenuous relationship between positive economic impacts in the short run and long term economic development based on an extractive, exhaustible natural resource. In addressing the relationship, proactive policy can make a difference.

Characteristics of the C Shale and D Shale reservoirs, Monterey Formation, Elk Hills Field, Kern County, California  

Science Conference Proceedings (OSTI)

The upper Miocene C Shale and D Shale reservoirs of the Elk Hills Shale Member of the Monterey Formation have cumulative oil and gas production much higher than the originally estimated recovery. These San Joaquin basin reservoirs are the lowest of the Stevens producing zones at Elk Hills and currently produce from a 2800-acre area on the 31 S anticline. The C Shale contains lower slope and basin plain deposits of very fine grained, thinly bedded, graded turbidites, pelagic and hemipelagic claystone, and slump deposits. Although all units are oil-bearing, only the lower parts of the graded turbidity intervals have sufficient horizontal permeability to produce oil. The D Shale consists of chart, claystone, carbonates and slump deposits, also originating in a lower slope to basin plain setting. All D Shale rock types contain oil, but the upper chart interval is the most productive. The chart has high matrix porosity, and due to a complex horizontal and vertical microfracture system, produces at a highly effective rate. Core samples indicate more oil-in-place is present in the thin, graded C Shale beds and in the porous D Shale chart than is identifiable from conventional electric logs. High gas recovery rates are attributed mostly to this larger volume of associated oil. Gas also enters the reservoirs from the adjacent 26R reservoir through a leaky normal fault. Significant gas volumes also may desorb from immature organic material common in the rock matrix.

Geochemical constraints on microbial methanogenesis in an unconventional gas reservoir: Devonian Antrim shale, Michigan  

Science Conference Proceedings (OSTI)

The Upper Devonian Antrim Shale is a self-sourced, highly fractured gas reservoir. It subcrops around the margin of the Michigan Basin below Pleistocene glacial drift, which has served as a source of meteoric recharge to the unit. The Antrim Shale is organic-rich (>10% total organic carbon), hydrogen-rich (Type I kerogen) and thermally immature (R[sub o] = 0.4 to 0.6). Reserve estimates range from 4-8 Tcf, based on assumptions of a thermogenic gas play. Chemical and isotopic properties measured in the formation waters show significant regional variations and probably delineate zones of increased fluid flow controlled by the fracture network. [sup 14]C determinations on dissolved inorganic carbon indicate that freshwater recharge occurred during the period between the last glacial advance and the present. The isotopic composition of Antrim methane ([delta][sup 13]C = -49 to -59[per thousand]) has been used to suggest that the gas is of early thermogenic origin. However, the highly positive carbon of co-produced CO[sub 2] gas ([delta][sup 13]C [approximately] +22[per thousand]) and DIC in associated Antrim brines ([delta][sup 13]C = +19 to +31[per thousand]) are consistent with bacterially mediated fractionation. The correlation of deuterium in methane ([delta]D = -200 to -260[per thousand]) with that of the co-produced waters (SD = -20 to -90176) suggests that the major source of this microbial gas is via the CO[sub 2] reduction pathway within the reservoir. Chemical and isotopic results also demonstrate a significant (up to 25%) component of thermogenic gas as the production interval depth increases. The connection between the timing of groundwater recharge, hydrogeochemistry and gas production within the Antrim Shale, Michigan Basin, is likely not unique and may find application to similar resources elsewhere.

Assessment of the Mexican Eagle Ford Shale Oil and Gas Resources  

E-Print Network (OSTI)

According to the 2011 Energy Information Agency (EIA) global assessment, Mexico ranks 4th in shale gas resources. The Eagle Ford shale is the formation with the greatest expectation in Mexico given the success it has had in the US and its liquids-rich zone. Accurate estimation of the resource size and future production, as well as the uncertainties associated with them, is critical for the decision-making process of developing shale oil and gas resources. The complexity of the shale reservoirs and high variability in its properties generate large uncertainties in the long-term production and recovery factors of these plays. Another source of uncertainty is the limited production history. Given all these uncertainties, a probabilistic decline-curve analysis approach was chosen for this study, given that it is relatively simple, it enables performing a play-wide assessment with available production data and, more importantly, it quantifies the uncertainty in the resource size. Analog areas in the US Eagle Ford shale were defined based on available geologic information in both the US and Mexico. The Duong model coupled with a Markov Chain Monte Carlo (MCMC) methodology was used to analyze and forecast production of wells located in the previously defined analog sectors in the US Eagle Ford shale. By combining the results of individual-well analyses, a type curve and estimated ultimate recovery (EUR) distribution for each of the defined analog sectors was obtained. These distributions were combined with well-spacing assumptions and sector areas to generate the prospective-resources estimates. Similar probabilistic decline-curve-analysis methodology was used to estimate the reserves and contingent resources of existing wells. As of March 2013, the total prospective resources (P90-P50-P10) for the Eagle Ford shale in Mexico (MX-EFS) are estimated to be 527-1,139-7,268 MMSTB of oil and 17- 37-217 TSCF of gas. To my knowledge, this is the first oil estimate published for this formation in Mexico. The most attractive sectors based on total estimated resources as well as individual-well type curves are located in the southeast of the Burgos Basin and east-west of the Sabinas basin. Because there has been very little development to date, estimates for reserves and contingent resources are much lower than those for prospective resources. Estimated reserves associated with existing wells and corresponding offset well locations are 18,375-34,722-59,667 MMSCF for gas and zero for oil. Estimated contingent resources are 14-64-228 MSTB of oil and 8,526-13,327- 25,983MMSCF of gas. The results of this work should provide a more reliable assessment of the size and uncertainties of the resources in the Mexican Eagle Ford shale than previous estimates obtained with less objective methodologies.

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

Science Conference Proceedings (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. 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. 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.

Silurian shale origin for light oil, condensate, and gas in Algeria and the Middle East  

SciTech Connect

Two of the largest gas fields in the world, Hasi R'Mel, Algeria and North Dome, Qatar, also contain substantial condensate and light oil reserves. Gas to source rock geochemical correlation is difficult due to the paucity of molecular parameters in the former although stable isotope composition is invaluable. However, by correlating source rocks with light oils and condensates associated with gas production using traditional geochemical parameters such as biomarkers and isotopes, a better understanding of the origin of the gas is achieved. Much of the crude oil in the Ghadames/Illizi Basins of Algeria has long been thought to have been generated from Silurian shales. New light oil discoveries in Saudi Arabia have also been shown to originate in basal euxinic Silurian shales. Key sterane and terpane biomarkers as well as the stable carbon isotopic compositions of the C15+ saturate and aromatic hydrocarbon fractions allow for the typing of Silurian-sourced, thermally mature light oils in Algeria and the Middle East. Even though biomarkers are often absent due to advanced thermal maturity, condensates can be correlated to the light oils using (1) carbon isotopes of the residual heavy hydrocarbon fractions, (2) light hydrocarbon distributions (e.g., C7 composition), and (3) compound specific carbon isotopic composition of the light hydrocarbons. The carbon isotopes of the C2-C4 gas components ran then be compared to the associated condensate and light oil isotopic composition.
