Technically recoverable Devonian shale gas in Kentucky  

SciTech Connect (OSTI)

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

Technically recoverable Devonian shale gas in Ohio  

SciTech Connect (OSTI)

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

Geologic analysis of Devonian Shale cores  

SciTech Connect (OSTI)

Cleveland Cliffs Iron Company was awarded a DOE contract in December 1977 for field retrieval and laboratory analysis of cores from the Devonian shales of the following eleven states: Michigan, Illinois, Indiana, Ohio, New York, Pennsylvania, West Virginia, Maryland, Kentucky, Tennessee and Virginia. The purpose of this project is to explore these areas to determine the amount of natural gas being produced from the Devonian shales. The physical properties testing of the rock specimens were performed under subcontract at Michigan Technological University (MTU). The study also included LANDSAT information, geochemical research, structural sedimentary and tectonic data. Following the introduction, and background of the project this report covers the following: field retrieval procedures; laboratory procedures; geologic analysis (by state); references and appendices.

Devonian shale gas resource assessment, Illinois basin  

SciTech Connect (OSTI)

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

Evaluation of Devonian shale potential in New York  

SciTech Connect (OSTI)

This report is a brief overview of preliminary geologic interpretations developed from the Eastern Gas Shales Project (EGSP) and related data concerning the deposition of the black shale facies and generation of natural gas in the Devonian shale sequence. The intent is to suggest areas of potential shale gas accumulation that would be of interest to the producer as either a primary target or a dual completion possibility. In New York, historical stratigraphic as well as current EGSP work has established the Devonian clastic facies as the type section for eastern North America. The initial documented shale-gas well was drilled in 1821 near Fredonia, New York. Since then, numerous shale-gas wells and/or deeper wells with gas shows in the shale section have been reported in western and central New York. The EGSP has focused on documenting and more closely defining organic-rich, black shale facies to project potential favorable trends. 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 New York. 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.

Evaluation of Devonian shale potential in Eastern Kentucky/Tennessee  

SciTech Connect (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 eastern Kentucky and Tennessee. Geologic data and interpretations are summarized, and areas where the accumulation of gas may be large enough to justify commercial production are outlined.

Material properties of Devonian shale for stimulation-technology development  

SciTech Connect (OSTI)

Material properties are used in the design of hydraulic fracturing treatments to establish a relation between the volume of fluid used in a job and the expected extent of the fracture. In Devonian shales this is important in determining the volume of fluid necessary to intersect the natural fracture system. In an attempt to provide a consistent and self-contained data base on the physical properties of Devonian shale, Science Applications has reviewed and collected previously generated data from numerous sources and has performed additional experiments so as to define the applicability of some of the quasi-static data to the evaluation of dynamic treatments. The review, experiments and evaluation which have been conducted on Devonian shale physical properties have resulted in the following principle conclusions: the elastic properties and yield surfaces defined by triaxial tests on Devonian shale may be significantly dependent upon shale type and organic richness, but a more systematic approach to core selection and testing will be required to establish correlations. Sufficient material property data for modeling and stimulation design exist only on a very site-specific basis, and more testing is required for identifying generic and regional trends. Dynamic experiments employing modified split-Hopkinson-bar techniques were so controlled by anisotropic sample failure that quantitative data on dynamic yield strength could not be obtained. There is a strong need for the development of experimental techniques and the generation of concordant data on the dynamic yield characteristics of Devonian shale at strain rates representative of explosive and tailored-pulse-loading. 9 figures, 17 tables.

Reactive gases evolved during pyrolysis of Devonian oil shale  

SciTech Connect (OSTI)

Computer modeling of oil shale pyrolysis is an important part of the Lawrence Livermore National Laboratory (LLNL) Oil Shale Program. Models containing detailed chemistry have been derived from an investigation of Colorado oil shale. We are currently attempting to use models to treat more completely reactions of nitrogen and sulfur compounds in the retort to better understand emissions. Batch retorting work on Devonian oil shale is proving particularly useful for this study of nitrogen/sulfur chemistry. Improved analytical methods have been developed to quantitatively determine reactive volatiles at the parts-per-million level. For example, the triple quadrupole mass spectrometer (TQMS) is used in the chemical ionization (CI) mode to provide real-time analytical data on ammonia evolution as the shale is pyrolyzed. A heated transfer line and inlet ensure rapid and complete introduction of ammonia to the instrument by preventing water condensation. Ammonia and water release data suitable for calculating kinetic parameters have been obtained from a New Albany Shale sample. An MS/MS technique with the TQMS in the electron ionization (EI) mode allows hydrogen sulfide, carbonyl sulfide, and certain trace organic sulfur compounds to be monitored during oil shale pyrolysis. Sensitivity and selectivity for these compounds have been increased by applying artificial intelligence techniques to tuning of the spectrometer. Gas evolution profiles (100 to 900/sup 0/C) are reported for hydrogen sulfide, water, ammonia, and trace sulfur species formed during pyrolysis of Devonian oil shale. Implications for retorting chemistry are discussed. 18 refs., 11 figs., 3 tabs.

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

SciTech Connect (OSTI)

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

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.

Plants of Devonian-Mississippian black shales, eastern interior, USA  

SciTech Connect (OSTI)

Macrofossils of the New Albany shale and equivalents of Late Devonian of Early Mississippian age in the east-central United States are known from three main floras or assemblages. One flora is almost entirely composed of Callixylon logs, slabs, and slivers, presumed to be driftwood permineralized after burial. Callixylon fossils are most abundant in the upper part of the Clegg Creek Member of the New Albany shale (Famennian) and equivalent strata in western New York, Ohio, and contiguous areas, perhaps because these Propymnosperms reached the zenith of their development at that time. A second, and later, flora consists principally of permineralized wood pieces (phosphatized free-wood or concretions) of stems, rachises, petioles, and possibly even mid-veins of pinnules of diverse members of the Lycopsida, Sphenopsida, Cladoxylales, Coenopteridales, Progymnospermae, and Pteridospermae. The principal concentration of these stem and petiolar segments is in the Falling Run Member of Sanderson Formation of the New Albany shale on the west side of the Cincinnati arch in southern Indiana and Kentucky, and in central Kentucky in the low saddle between the Cincinnati arch proper and its southward extension as the Nashville dome. The third type of macrofossil plant assemblage is consituted of Foerstia. These plants are considered to be algal in origin and indicate no clear relationship either to distance from shore or depth of water. The main concentration is in middle and lower New Albany shale and equivalents. It is also found sparingly in West Virginia and Michigan and much farther west (one specimen from the Exshaw shale of Montana).

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

SciTech Connect (OSTI)

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

Evaluation of Devonian shale potential in the Michigan basin  

SciTech Connect (OSTI)

The purpose of this report is to inform interested oil and gas operators about EGSP results as they pertain to the Devonian gas shales of the Michigan basin. 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. However, a conservative estimate of in place resource for the Michigan basin is 76 TCF (Zielinski and McTver 1980. How much of this resource can be recovered using present technology has not been estimated. 27 refs., 15 figs., 2 tabs.

The use of Devonian oil shales in the production of portland cement  

SciTech Connect (OSTI)

The Lafarge Corporation operates a cement plant at Alpena, Michigan in which Antrim shale, a Devonian oil shale, is used as part of the raw material mix. Using this precedent the authors examine the conditions and extent to which spent shale might be utilized in cement production. They conclude that the potential is limited in size and location but could provide substantial benefit to an oil shale operation meeting these criteria.

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

SciTech Connect (OSTI)

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

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

SciTech Connect (OSTI)

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

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

SciTech Connect (OSTI)

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

Eastern mineback: study of advanced stimulation/production in the Devonian shales  

SciTech Connect (OSTI)

The Eastern Gas Shale Mineback Program has evolved from an assessment of the state-of-the-art problems of gas recovery from the eastern Devonian shales. After 10 years of Devonian shale research conducted under the direction of the Eastern Gas Shale Project (EGSP) Office at the U.S. DOE's Morgantown Energy Technology Center (METC), the remaining major issues for developing the shale resource have been defined, and this program has been formulated to address those specific recovery problems. Numerous field, laboratory, and theoretical stimulation studies have been conducted. However, the large number of reservoir pre-existing, unmeasureable conditions and the numerous post-stimulation effects that cannot be measured or observed have virtually stagnated further stimulation technology development through the normal indirect engineering research and development approach.

Sedimentology of gas-bearing Devonian shales of the Appalachian Basin  

SciTech Connect (OSTI)

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

Devonian oil shale of the eastern United States: a major American energy resource  

SciTech Connect (OSTI)

The eastern Devonian oil shale resource can yield 400 billion (400 X 10/sup 9/) bbl of synthetic oil, if all surface and near-surface shales were strip or deep mined for above-ground hydroretorting. Experimental work, in equipment capable of processing up to 1 ton/h of shale, has confirmed the technical and economic feasibility of aboveground hydroretorting of oil shales. Work done to date on nearly 500 samples from 12 states indicates that the HYTORT Process can give organic carbon recoveries from 2 to 2.5 times those of conventional retorting of the Devonian shales, so that the HYTORT Process yields 25 to 30 gallons per ton on syncrude at many localities, compared with 10 to 15 gallons per ton using Fischer Assay retort methods. Criteria for inclusion of shale in estimates of recoverable resources for the HYTORT Process are: (1) organic carbon of at least 10% by weight; (2) overburden of less than 200 feet (59 meters); (3) volumetric stripping ratios of less than 2.5 to 1; and (4) stratigraphic thickness of 10 feet (3 meters) or more. Resource estimates include: Kentucky (Ohio, New Albany, and Sunbury shales), 190 billion (190 X 10/sup 9/) barrels (bbl); Ohio (Ohio and Sunbury shales), 140 billion bbl; Tennessee (Chattanooga shale), 44 billion bbl; Indiana (New Albany shale), 40 billion bbl; Michigan (Antrim shale), 5 billion bbl; and Alabama (Chattanooga shale), 4 billion bbl. Recoverable resources have not been identified in West Virginia, Georgia, Oklahoma, Illinois, Arkansas, or Missouri outcrops. Co-production of uranium and metals is a possibility in the areas favorable for syncrude production.

A formation of black carbonaceous shale, later named the New Albany Shale, was first recognized in 1837 and reported in 1839 by David D. Owen. Since then, the New Albany has been the subject of numerous investigations by individuals affiliated with the Indiana Geological Survey and others. The present comprehensive investigation, involves petrology, mineralogy, stratigraphy, geomorphology, organic and inorganic geochemistry, and physical properties. The lower part of the New Albany Shale is late Middle Devonian in age, and the upper part is Early Mississippian in age.

Devonian-Mississippian oil shale resources of Kentucky: a summary  

SciTech Connect (OSTI)

Assessment of the oil shale resources in Kentucky has continued with 75 NX cores available where the oil shale crops out or is overlain by relatively thin cover in the area from Estill County westward to Bullitt County. In this 14 county area, the total black shale section thins across the crest of the Cincinnati arch and changes stratigraphically from that characteristic of the Ohio Shale in Estill County to that of the New Albany Shale in Bullitt County. Despite this stratigraphic transition the two high-carbon zones (greater than 8.0% carbon) can be traced across the arch. As the traverse is followed from the east, the intervening low-carbon zones thin such that at the crest of the arch, there are areas where the entire section of black shale contains more than 8% carbon. Then upon leaving the crest the two high-carbon zones separate again with one remaining at the very top of the section and one in the lower part. In the 14 county area, there are approximately 3.8 x 10/sup 5/ acres of oil shale outcrop and approximately 7.8 x 10/sup 5/ acres underlain by oil shale at relatively shallow depths.

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

SciTech Connect (OSTI)

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

Organic-matter preservation in Chattanooga Shale: revised Late Devonian correlations, Kentucky and Tennessee  

SciTech Connect (OSTI)

Continued interest in the carbon-rich shale of Devonian and Mississippian age in Kentucky is reflected by intensive leasing and drilling to evaluate the potential reserves of oil shale. Thicker accumulations of shale suitable for surface extraction lie along the flanks of the Cincinnati arch in both the Illinois and Appalachian basins. The shale tends to thin across the Cincinnati arch by an order of magnitude (100 versus 10 m, 330 versus 33 ft), and individual units disappear entirely. Key beds have been used with mixed success in tracing these changes. Recognition of these key beds in cores provided by a recently completed 70-core drilling program in and near the outcrop is the basis for revising earlier suggested correlations. One key bed, marked by the occurrence of the alga. Foerstia (Protosalvinia), occurs in the lower part of the lower (Huron) member of the Ohio Shale in the Appalachian basin. The Huron Member is overlain by a lithostratigraphic marker, the Three Lick Bed. The Foerstia Zone has been traced in core and outcrop to the upper part of the uppermost (Clegg Creek) member of the New Albany Shale in the Illinois basin. Discovery in this widespread continuous biostratigraphic marker at the top of the upper (Gassaway) member of the Chattanooga Shale near the designated reference section in Dekalb County, Tennessee, suggests that the Three Lick Bed of the Ohio Shales does not correlate with the unit of the Gassaway Member of the Chattanooga Shale as thought. Field relations indicate that the Three Lick Bed is absent by nondeposition, and starved-basin conditions prevailed into Early Mississippian time in this part of Tennessee.

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

SciTech Connect (OSTI)

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

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

SciTech Connect (OSTI)

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

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

Inorganic geochemistry of Devonian shales in southern West Virginia: geographic and stratigraphic trends  

SciTech Connect (OSTI)

Samples of cuttings from twenty-one wells and a core from a single well in southern West Virginia were analyzed for major and minor elements: silicon, aluminum, iron, magnesium, calcium, sodium, titanium, phosphorus, manganese, sulfur, zinc, and strontium. Stratigraphic and geographic controls on elemental abundances were studied through canonical correlations, factor analyses, and trend surface analyses. The most abundant elements, silicon and aluminum, show gradual trends through the stratigraphic column of most wells, with silicon increasing and aluminum decreasing up-section. Other elements such as calcium, sulfur, and titanium change abruptly in abundance at certain stratigraphic boundaries. Important geographic trends run east-west: for instance, one can see an increase in sulfur and a decrease in titanium to the west; and a decrease in silicon from the east to the central part of the study area, then an increase further west. Although observed vertical trends in detrital minerals and geographic patterns in elemental abundances agree with the accepted view of a prograding delta complex during Late Devonian time, geographically-local, time restricted depositional processes influenced elemental percentages in subsets of the wells and the stratigraphic intervals studied. The black shales of lower Huron age do not represent simply a return of depositional conditions present in the earlier Rhinestreet time; nor do the gray shales of the Ohio Shale represent the same environmental conditions as the Big White Slate.

Tectonic and flexural significance of Middle Devonian graben-fill sequence in new Albany shale, central Kentucky  

SciTech Connect (OSTI)

The third tectonic phase of the Acadian orogeny began in the late Middle Devonian, and the sedimentary record of that event is largely restricted to the deeper, more proximal portions of the Appalachian foreland and Illinois intercratonic basins. Much of the intervening area, on and near the Cincinnati arch, was uplifted and subjected to erosion by movement on the peripheral bulge accompanying the initiation of the third tectonic phase. However, bulge movement also reactivated basement fault systems in Kentucky and created a series of grabens that were filled with eroded sediments and debris flows from adjacent horsts. Although rarely preserved, a buried Devonian graben along Carpenter Fork in Boyle County, central Kentucky, reveals such a sequence. The graben is bounded by upthrown blocks of Middle Devonian Boyle Dolomite, which also floors the graben. Within the graben a black-shale unit, apparently absent elsewhere, conformably overlies the Boyle and grades upward into debris-flow deposits represented by the Duffin breccia facies of the New Albany Shale. The Duffin contains clasts of the shale, as well as of chert, silicified fossils, and fine to boulder-size dolostone clasts eroded from the Boyle high on the flanks of the graben. The underlying shale also exhibits evidence of penecontemporaneous soft-sediment deformation related to the debris-flow emplacement of Boyle residue in the graben and due to later loading by the Duffin.

Stratigraphy and organic petrography of Mississippian and Devonian oil shale at the Means Project, East-Central Kentucky  

SciTech Connect (OSTI)

The Means Oil Shale Project is under consideration for financial assistance by the US Synthetic Fuels Corporation. The project site is located in southern Montgomery County, about 45 miles east of Lexington, Kentucky. In the site area the Devonian Ohio Shale and the Mississippian Sunbury Shale are under study; these oil shales were deposited in the Appalachian Basin. The objective of the Means Project is to mine, using open pit methods, an ore zone which includes the Sunbury and upper Cleveland and which excludes the Bedford interburden. The thick lower grade oil shale below this ore zone renders the higher grade shale at the base of the Huron commercially unattractive. The oil shale at Means has been classified as a marinite, an oil shale containing abundant alginite of marine origin. Lamalginite is the dominant liptinite and comprises small, unicellular alginite with weak to moderate fluorescence at low rank and a distinctive lamellar form. Telalginite, derived from large colonial or thick-walled, unicellular algae, is common in several stratigraphic intervals.

Paleoecology of the Devonian-Mississippian black-shale sequence in eastern Kentucky with an atlas of some common fossils  

SciTech Connect (OSTI)

The Devonian-Mississippian black-shale sequence of eastern North America is a distinctive stratigraphic interval generally characterized by low clastic influx, high organic production in the water column, anaerobic bottom conditions, and the relative absence of fossil evidence for biologic activity. The laminated black shales which constitute most of the black-shale sequence are broken by two major sequences of interbedded greenish-gray, clayey shales which contain bioturbation and pyritized micromorph invertebrates. The black shales contain abundant evidence of life from upper parts of the water column such as fish fossils, conodonts, algae and other phytoplankton; however, there is a lack of evidence of benthic life. The rare brachiopods, crinoids, and molluscs that occur in the black shales were probably epiplanktic. A significant physical distinction between the environment in which the black sediments were deposited and that in which the greenish-gray sediments were deposited was the level of dissolved oxygen. The laminated black shales point to anaerobic conditions and the bioturbated greenish-gray shales suggest dysaerobic to marginally aerobic-dysaerobic conditions. A paleoenvironmental model in which quasi-estuarine circulation compliments and enhances the effect of a stratified water column can account for both depletion of dissolved oxygen in the bottom environments and the absence of oxygen replenishment during black-shale deposition. Periods of abundant clastic influx from fluvial environments to the east probably account for the abundance of clays in the greenish-gray shale as well as the small amounts of oxygen necessary to support the depauparate, opportunistic, benthic faunas found there. These pulses of greenish-gray clastics were short-lived and eventually were replaced by anaerobic conditions and low rates of clastic sedimentation which characterized most of black-shale deposition.

Oil shale and coal in intermontane basins of Thailand  

SciTech Connect (OSTI)

The Mae Tip intermontane basin contains Cenozoic oil shales in beds up to 1 m (3.3 ft) thick interbedded with coal and mudstone. The oil shales contain lamosite-type alginite, and give a maximum oil yield of 122 L/MT (29.3 gal/ton). The beds are laterally continuous for at least 1.5 km (1.0 mi), but pass into mudstones toward the basin margin. The oil shales originated when peat swamps close to a steep basin margin were flooded by shallow lakes, allowing algae to replace rooted vegetation. This distinctive oil shale-coal assemblage is known from many small intermontane basins in Thailand, where locally high geothermal gradients suggest potential for hydrocarbons.

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

SciTech Connect (OSTI)

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

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

SciTech Connect (OSTI)

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

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

SciTech Connect (OSTI)

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

Regional geological assessment of the Devonian-Mississippian shale sequence of the Appalachian, Illinois, and Michigan basins relative to potential storage/disposal of radioactive wastes  

SciTech Connect (OSTI)

The thick and regionally extensive sequence of shales and associated clastic sedimentary rocks of Late Devonian and Early Mississippian age has been considered among the nonsalt geologies for deep subsurface containment of high-level radioactive wastes. This report examines some of the regional and basin-specific characteristics of the black and associated nonblack shales of this sequence within the Appalachian, Illinois, and Michigan basins of the north-central and eastern United States. Principal areas where the thickness and depth of this shale sequence are sufficient to warrant further evaluation are identified, but no attempt is made to identify specific storage/disposal sites. Also identified are other areas with less promise for further study because of known potential conflicts such as geologic-hydrologic factors, competing subsurface priorities involving mineral resources and groundwater, or other parameters. Data have been compiled for each basin in an effort to indicate thickness, distribution, and depth relationships for the entire shale sequence as well as individual shale units in the sequence. Included as parts of this geologic assessment are isopach, depth information, structure contour, tectonic elements, and energy-resource maps covering the three basins. Summary evaluations are given for each basin as well as an overall general evaluation of the waste storage/disposal potential of the Devonian-Mississippian shale sequence,including recommendations for future studies to more fully characterize the shale sequence for that purpose. Based on data compiled in this cursory investigation, certain rock units have reasonable promise for radioactive waste storage/disposal and do warrant additional study.

Rock-eval data relating to oil-source potential of shales of New Albany group (Devonian-Mississippian) in Illinois basin  

SciTech Connect (OSTI)

Only limited data on petroleum source rock potential of New Albany Group (Devonian-Mississippian) shales have been reported, with the exception of vitrinite reflectance and some petrographic analyses. The New Albany Group contains the thickest and most widespread continuous black shale beds in the Illinois basin. The New Albany extends from northwestern Illinois to southwestern Indiana and western Kentucky and is thought to have played a major role in petroleum generation throughout the basin. In this study, Rock-Eval pyrolysis was used to measure the petroleum-generative potential and production index of the shale. Seven geochemical logs, based on 143 core samples from across the basin, and a production index map, based on a total of 252 samples (cuttings and cores) in Illinois, were generated. Systematic variations of petroleum-generative potential of the shale were observed. The variations are related to the differences in shale lithofacies, depth, and geographic location. The upper portion of the New Albany - the Hannibal and Saverton Shales - has the lowest oil-generative potential. The Grassy Creek, Sweetland Creek, and other stratigraphically lower shales of the New Albany Group generally have good oil-generative potential. However, samples from the Hicks dome area of extreme southern Illinois are overmature and have no oil-generative potential. Source rocks that have both good oil-generative potential (> 6 kg hydrocarbons per ton of rock) and a higher production index (> 0.09) are generally located at depths of 2,500-5,300 ft.

Orientation of tectonic stresses in central Kentucky during U. Devonian/L. Mississippian times: Evidence from quartz veins (after gypsum) in NE-trending, systematic joints in shales  

SciTech Connect (OSTI)

Quartz replacing fibrous gypsum and anhydrite pseudomorphically (QAS; quartz after sulfate''), and preserving characteristic crack-seal'' and chickenwire'' textures, occurs in extensional veins at four locations in central KY. The veins occupy a systematic set of NE-SW-trending, vertical joints within the essentially flat-lying shales of the Renfro Member of the Mississippian Borden Formation and the Late Devonian New Albany Shale. The four QAS occurrences discovered to date are located northeast of the Borden Front. At one site in the New Albany Shale, QAS veins show clear evidence of penecontemporaneous deformation. It is proposed that at all QAS locations, gypsum precipitated in incipient joints before complete lithification of the sediment, and grew perpendicular to the fractures to form extensional veins in the soft but firm muds. The orientations of the joints now marked by QAS veins are broadly consistent with regional patterns of NE-SW-trending systematic joints and lineaments in southern IN and in central and eastern KY. These systematic fracture patterns do not correspond directly to known basement faults or rift systems, although they are consistent with modern stress directions in eastern and western KY, measured in situ in wells and by earthquake fault-plane solutions. It is proposed that this systematic trend marks the regional tectonic stress pattern characteristic of southern IN and central and eastern KY at, and since the Late Devonian. The evidence of penecontemporaneous sedimentary deformation in joints of U. Devonian age, marked and preserved by quartz replacement of early gypsum, is sufficient to show that while the systematic NE-trending joint set in KY may also be modern it is not uniquely so.

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

Science Journals Connector (OSTI)

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

Decaking of coal or oil shale during pyrolysis in the presence of iron oxides  

DOE Patents [OSTI]

A method for producing a fuel from the pyrolysis of coal or oil shale in the presence of iron oxide in an inert gas atmosphere is described. The method includes the steps of pulverizing feed coal or oil shale, pulverizing iron oxide, mixing the pulverized feed and iron oxide, and heating the mixture in a gas atmosphere which is substantially inert to the mixture so as to form a product fuel, which may be gaseous, liquid and/or solid. The method of the invention reduces the swelling of coals, such as bituminous coal and the like, which are otherwise known to swell during pyrolysis. 4 figs., 8 tabs.

SciTech Connect (OSTI)

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

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

Science Journals Connector (OSTI)

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

Sulfide, phosphate, and minor element enrichment in the New Albany Shale (Devonian-Mississippian) of southern Indiana  

SciTech Connect (OSTI)

The upper part of the New Albany Shale is divided into three members, which in ascending order are: (1) the Morgan Trail Member, a laminated brownish-black shale; (2) the Camp Run Member, an interbedded brownish-black and greenish-gray shale; and (3) the Clegg Creek Member, also a laminated brownish-black shale. The Morgan Trail and Camp Run Members contain 5 to 6% total organic carbon (TOC) and 2% sulfide sulfur. Isotopic composition of sulfide in these members ranges from -5.0 to -20.0%. C/S plots indicate linear relationships between abundances of these elements characteristic of sediments deposited in a noneuxinic marine environment. The Clegg Creek Member contains 10 to 15% TOC and 2 to 6% sulfide sulfur. Isotopic composition of sulfide ranges from -5.0 to -40.0%. The most negative values are characteristic of syngenetic pyrite formed within an anoxic water column. Abundances of carbon and sulfur are higher and uncorrelated in this member, consistent with deposition in an euxinic environment. Further, DOP (degree of pyritization) values suggest that pyrite formation was generally iron limited throughout Clegg Creek deposition, but sulfur isotopes indicate that syngenetic (water column) pyrite becomes an important component in the sediment only in the upper part of the member. At the top of the Clegg Creek Member a zone of phosphate nodules and trace metal enrichment coincides with maximal TOC values. During euxinic deposition, phosphate and trace metals accumulated below the chemocline due to limited vertical circulation in the water column. Phosphate and trace metals released for organic matter during early diagenesis resulted in precipitation of metal-rich phosphate nodules.

Comparison of organic-rich shales of Pennsylvanian age in Indiana with New Albany Shale  

SciTech Connect (OSTI)

Abundant black organic-rich shales occur in rocks of Pennsylvanian age in southwestern Indiana. They have not been well characterized except for a few thin intervals in small areas, the best example being at the abandoned Mecca Quarry in west-central Indiana. Although these shales are thinner and less widespread than the organic-rich shales of the New Albany Shale (Devonian and Mississippian age) they warrant characterization because of their accessibility during strip mining of underlying coals. Organic-rich shales of Pennsylvanian age contain up to 44% organic carbon and might be considered potential oil shales. Carbon to hydrogen ratios in these shales are similar to those in the New Albany. Relatively high concentrations of certain metals occur in shales of both ages, especially where phosphate is abundant, and sulfur values for both shales range from < 1 to 6%. Sulfur values are much higher for thin pyrite-rich units. Siderite nodules are common in Pennsylvania shales, but little siderite if found in the New Albany. Dolomite, commonly ferroan, and calcite in a variety of forms are the dominant carbonates in the New Albany. Some Pennsylvanian shales may contain large fossils or mica flakes, but such coarse-grained features are uncommon in the New Albany Shale.

Liquid hydrocarbon fuels derived from coal and from oil shale were made available for characterization and thermal and storage stability investigations. The coal-derived liquids identified as naphthas from No. 6 Illinois and Wyodak coals produced by the Exxon Donor Solvent process contained high concentrations of oxygen, nitrogen, and sulfur compounds and were considered to be unrefined synthetic crudes. These materials were found to be relatively unstable in storage. The shale-derived fuels were refined to meet the requirements of military specification jet fuels JP-8 and JP-5 and marine diesel fuel (DFM). Virtually all the specification requirements were met and the fuels were found to be thermally and storage stable. During 32-week, 43/sup 0/C storage tests conducted on these liquids, periodic measurements were made of precipitate fuel-insolubles, fuel-soluble gum, dissolved oxygen content and peroxide number. The liquids were analyzed, in some instances, by infrared, NMR, and uv spectroscopy, before and after the 32-week storage test with little or no change being observed in the bulk liquid samples. Shale-derived liquid hydrocarbons have been refined to meet current specification requirements for hydrocarbon fuels, and it appears that coal-derived liquids can also be refined to meet requirements for performance and storage stability.

Co-Firing Oil Shale with Coal and Other Fuels for Improved Efficiency and Multi-Pollutant Control  

SciTech Connect (OSTI)

Oil shale is an abundant, undeveloped natural resource which has natural sorbent properties, and its ash has natural cementitious properties. Oil shale may be blended with coal, biomass, municipal wastes, waste tires, or other waste feedstock materials to provide the joint benefit of adding energy content while adsorbing and removing sulfur, halides, and volatile metal pollutants, and while also reducing nitrogen oxide pollutants. Oil shale depolymerization-pyrolysis-devolatilization and sorption scoping studies indicate oil shale particle sorption rates and sorption capacity can be comparable to limestone sorbents for capture of SO2 and SO3. Additionally, kerogen released from the shale was shown to have the potential to reduce NOx emissions through the well established “reburning” chemistry similar to natural gas, fuel oil, and micronized coal. Productive mercury adsorption is also possible by the oil shale particles as a result of residual fixed-carbon and other observed mercury capture sorbent properties. Sorption properties were found to be a function particle heating rate, peak particle temperature, residence time, and gas-phase stoichmetry. High surface area sorbents with high calcium reactivity and with some adsorbent fixed/activated carbon can be produced in the corresponding reaction zones that exist in a standard pulverized-coal or in a fluidized-bed combustor.

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

Science Journals Connector (OSTI)

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

Southern tie section: a stratigraphic section through the Devonian-Mississippian black-shale sequence in Ohio, Kentucky, West Virginia, and Virginia  

SciTech Connect (OSTI)

The map of the Southern Tie Section is a sequel to the Preliminary Stratigraphic Cross Section of Kepferle, Wilson, and Ettensohn (1978) and uses many of the datum points of that publication. Sample descriptions and other geophysical log curves in addition to the gamma ray (natural radioactivity) curve are used for correlation; and the geology of the substrates of the shale sequence is examined for its relation to that of the sequence itself. The section uses the Base of the Sunbury shale (rather than the base of the shale sequence) as the stratigraphic datum in order better to visualize syndepositional and earlier tectonism which affect the distribution and internal constitution of the sequence. This convention shows elegantly the onlap of the sequence upon the Cincinnati Arch, but does not so readily point out the meaning of the Wildcat Valley Sandstone in the Greendale Syncline at the southeast end of the section.

Coal rank trends in western Kentucky coal field and relationship to hydrocarbon occurrence  

SciTech Connect (OSTI)

Extensive oil and gas development has occurred in the high volatile C bituminous region north of the Rough Creek fault zone, but few pools are known within the Webster syncline south of the fault zone. The rank of the Middle Pennsylvanian coals can be used to estimate the level of maturation of the Devonian New Albany Shale, a likely source rock for much of the oil and gas in the coal field. Based on relatively few data points, previous studies on the maturation of the New Albany Shale, which lies about 1 km below the Springfield coal, indicate an equivalent medium volatile bituminous (1.0-1.2% R{sub max}) rank in the Fluorspar district. New Albany rank decreases to an equivalent high volatile B/C (0.6% R{sub max}) north of the Rough Creek fault zone. Whereas the shale in the latter region is situated within the oil generation window, the higher rank region is past the peak of the level of maturation of the New Albany Shale. The significance of the New Albany reflectancy is dependent on the suppression of vitrinite reflectance in organic-rich shales. The possibility of reflectance suppression would imply that the shales could be more mature than studies have indicated.

Low temperature pyrolysis of coal or oil shale in the presence of calcium compounds  

DOE Patents [OSTI]

A coal pyrolysis technique or process is described in which particulate coal is pyrolyzed in the presence of about 5 to 21 wt. % of a calcium compound selected from calcium oxide, calcined (hydrate) dolomite, or calcined calcium hydrate to produce a high quality hydrocarbon liquid and a combustible product gas which are characterized by low sulfur content. The pyrolysis is achieved by heating the coal-calcium compound mixture at a relatively slow rate at a temperature of about 450.degree. to 700.degree. C. over a duration of about 10 to 60 minutes in a fixed or moving bed reactor. The gas exhibits an increased yield in hydrogen and C.sub.1 -C.sub.8 hydrocarbons and a reduction in H.sub.2 S over gas obtainable by pyrolyzing cola without the calcium compound. The liquid product obtained is of a sufficient quality to permit its use directly as a fuel and has a reduced sulfur and oxygen content which inhibits polymerization during storage.

NATURAL GAS FROM SHALE: Questions and Answers  

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

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

New Albany shale group of Illinois  

SciTech Connect (OSTI)

The Illinois basin's New Albany shale group consists of nine formations, with the brownish-black laminated shales being the predominant lithology in southeastern Illinois and nearby parts of Kentucky where the group reaches its maximum thickness of 460 ft. A second depositional center lies in west-central Illinois and southeastern Iowa, where the group is about 300 ft thick and the predominant lithology is bioturbated olive-gray to greenish-gray shale. A northeast-trending area of thin strata (mostly interfingering gray and black shales) separates these two depocenters. The distribution and types of lithofacies in the New Albany suggest that the shale was deposited across a shelf-slope-basin transition in a marine, stratified anoxic basin. The record of depositional events in the shale group could serve as a baseline for interpreting the history of tectonically more complex sequences such as the Appalachian basin's Devonian shales.

Oil shale technology  

SciTech Connect (OSTI)

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

Geologic and geochemical studies of the New Albany Group (Devonian Black Shale) in Illinois to evaluate its characteristics as a source of hydrocarbons. Quarterly progress report, January 1-March 31, 1980  

SciTech Connect (OSTI)

This project is a detailed analysis of the lithology, stratigraphy, and structure of the New Albany Group in Illinois to determine those characteristics of lithology, thickness, regional distribution, vertical and lateral variability, and deformation that are most relevant to the occurrence of hydrocarbons. The mineralogic and petrographic properties of the New Albany Shale in Illinois are characterized. This includes the quantitative and qualitative characterization, by optical and x-ray techniques, of the inorganic mineral constituents, the dispersed organic matter, and the fabric of the shale. Not less than 49 major, minor, and trace elements are determined in 300 to 500 shale samples, which are representative cross sections of the cores taken. Organic and mineral carbon are included; total hydrogen; total sulfur and when that exceeds 0.5%, pyritic and sulfate sulfur. Also, other elements observed during normal routine analysis are reported. The character of off-gases from approximately 10-foot intervals in cores collected in the Illinois Basin is determined. In addition, the relative distribution of hydrocarbons is determined in ten specially prepared core samples, which are the same as those in previous unit. The carbon isotopic composition of methane in off-gases is determined from core samples whenever sufficient methane can be collected. This data is compared to other pertinent data such as gas composition and vitrinite reflectance for the purpose of making interpretations as to the origin and maturity of the gas. Laboratory experiments are performed to study the relative effects and significance of chemical and isotopic fractionation that occurs as gas is released from core samples. Data accumulated can be evaluated to gain a better understanding of the origin, migration, and location of natural gas associated with the shales.

Research investigations in oil shale, tar sand, coal research, advanced exploratory process technology, and advanced fuels research: Volume 1 -- Base program. Final report, October 1986--September 1993  

SciTech Connect (OSTI)

Numerous studies have been conducted in five principal areas: oil shale, tar sand, underground coal gasification, advanced process technology, and advanced fuels research. In subsequent years, underground coal gasification was broadened to be coal research, under which several research activities were conducted that related to coal processing. The most significant change occurred in 1989 when the agreement was redefined as a Base Program and a Jointly Sponsored Research Program (JSRP). Investigations were conducted under the Base Program to determine the physical and chemical properties of materials suitable for conversion to liquid and gaseous fuels, to test and evaluate processes and innovative concepts for such conversions, to monitor and determine environmental impacts related to development of commercial-sized operations, and to evaluate methods for mitigation of potential environmental impacts. This report is divided into two volumes: Volume 1 consists of 28 summaries that describe the principal research efforts conducted under the Base Program in five topic areas. Volume 2 describes tasks performed within the JSRP. Research conducted under this agreement has resulted in technology transfer of a variety of energy-related research information. A listing of related publications and presentations is given at the end of each research topic summary. More specific and detailed information is provided in the topical reports referenced in the related publications listings.

SciTech Connect (OSTI)

The initial phase has been completed in the project to evaluate alternative fuels for highway transportation from synthetic crudes. Three refinery models were developed for Rocky Mountain, Mid-Continent and Great Lakes regions to make future product volumes and qualities forecast for 1995. Projected quantities of shale oil and coal oil syncrudes were introduced into the raw materials slate. Product slate was then varied from conventional products to evaluate maximum diesel fuel and broadcut fuel in all regions. Gasoline supplement options were evaluated in one region for 10% each of methanol, ethanol, MTBE or synthetic naphtha in the blends along with syncrude components. Compositions and qualities of the fuels were determined for the variation in constraints and conditions established for the study. Effects on raw materials, energy consumption and investment costs were reported. Results provide the basis to formulate fuels for laboratory and engine evaluation in future phases of the project.

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

Science Journals Connector (OSTI)

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

The project, {open_quotes}A New Innovative Exploitation Strategy for Gas Accumulations Within Pressure Compartments,{close_quotes} was a continuation of a project funded by the GRI Pressure Compartmentalization Program that began in 1990. That project, {open_quotes}Analysis of Pressure Chambers and Seals in the Powder River Basin, Wyoming and Montana,{close_quotes} characterized a new class of hydrocarbon traps, the discovery of which can provide an impetus to revitalize the domestic petroleum industry. In support of the UW Institute For Energy Research`s program on pressure compartmentalization, solid-state {sup 13}C NMR measurements were made on sets of shales and coals from different Laramide basins in North America. NMR measurements were made on samples taken from different formations and depths of burial in the Alberta, Bighorn, Denver, San Juan, Washakie, and Wind River basins. The carbon aromaticity determined by NMR was shown to increase with depth of burial and increased maturation. In general, the NMR data were in agreement with other maturational indicators, such as vitrinite reflectance, illite/smectite ratio, and production indices. NMR measurements were also obtained on residues from hydrous pyrolysis experiments on Almond and Lance Formation coals from the Washakie Basin. These data were used in conjunction with mass and elemental balance data to obtain information about the extent of carbon aromatization that occurs during artificial maturation. The data indicated that 41 and 50% of the original aliphatic carbon in the Almond and Lance coals, respectively, aromatized during hydrous pyrolysis.

Studies of New Albany shale in western Kentucky. Final report  

SciTech Connect (OSTI)

The New Albany (Upper Devonian) Shale in western Kentucky can be zoned by using correlative characteristics distinguishable on wire-line logs. Wells drilled through the shale which were logged by various methods provided a basis for zonation of the subsurface members and units of the Grassy Creek, Sweetland Creek, and Blocher. Structure and isopach maps and cross sections were prepared. The Hannibal Shale and Rockford Limestone were found in limited areas; isopach maps were not made for these members. Samples of cuttings from selected wells were studied in order to identify the contact of the shale with underlying and overlying rock units. A well-site examination of cuttings through the shale section was conducted, and the presence of natural gas was observed in the field. The New Albany Shale has the potential for additional commercially marketable natural gas production. Exploratory drilling is needed to evaluate the reservoir characteristics of the New Albany Shale.

The Arkansas Novaculite of southern Oklahoma and the Caballos Novaculite of west Texas (both Devonian) form fractured reservoirs in the Marathon-Ouachita thrust system. These formations were examined to ascertain their petroleum potential. Findings include the following. (1) The thermal maturity of the thrust system conforms to the maturity of the sequence that it has overthrust, suggesting that this allochthonous facies is not anomalously mature. (2) Shale units within the novaculites contain oil-prone organic matter in sufficient concentrations to constitute source rocks. (3) The composition of oils from Isom Springs field in southern Oklahoma and from McKay Creek field in west Texas is virtually identical and generally resembles Devonian oils in Oklahoma and west Texas. The authors concluded that the Devonian novaculites of the Marathon-Ouachita thrust system are self sourcing and do not require a fortuitous juxtaposition of source rocks of a different age to produce a commercial deposit.

Hydrotreating of oil from eastern oil shale  

SciTech Connect (OSTI)

Oil shale provides one of the major fossil energy reserves for the United States. The quantity of reserves in oil shale is less than the quantity in coal, but is much greater (by at least an order of magnitude) than the quantity of crude oil reserves. With so much oil potentially available from oil shale, efforts have been made to develop techniques for its utilization. In these efforts, hydrotreating has proved to be an acceptable technique for upgrading raw shale oil to make usuable products. The present work demonstrated the use of the hydrotreating technique for upgrading an oil from Indiana New Albany oil shale.

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

SciTech Connect (OSTI)

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

Application of the HYTORT process to oil shales throughout the world  

SciTech Connect (OSTI)

The HYTORT /sup R/ process is a unique oil shale retorting process which uses an atmosphere of hydrogen gas at elevated pressure to produce higher yields of oil than are possible using conventional thermal retorting techniques. In the U.S., HYTORT process development efforts have played a key role in recognition of the significance of the Devonian oil shales as a major fossil energy resource. The results presented in this paper show that application of the HYTORT process to oil shales of countries such as Sweden, Italy, Jordan, and Canada may yield equally significant results.

Microbial desulfurization of Eastern oil shale: Bioreactor studies  

SciTech Connect (OSTI)

The removal of sulfur from Eastern oil shale (40 microns particle size) slurries in bioreactors by mixed microbial cultures was examined. A mixed culture that is able to remove the organic sulfur from model sulfur compounds presenting coal as well as a mixed culture isolated from oil shale enrichments were evaluated. The cultures were grown in aerobic fed-batch bioreactors where the oil shale served as the source of all nutrients except organic carbon. Glucose was added as an auxiliary carbon source. Microbial growth was monitored by plate counts, the pH was checked periodically, and oil shale samples were analyzed for sulfur content. Results show a 24% reduction in the sulfur content of the oil shale after 14 days. The settling characteristics of the oil shale in the bioreactors were examined in the presence of the microbes. Also, the mixing characteristics of the oil shale in the bioreactors were examined. 10 refs., 6 figs., 5 tabs.

Pyrolysis of shale oil vacuum distillate fractions  

SciTech Connect (OSTI)

The freezing point of US Navy jet fuel (JP-5) has been related to the amounts of large n-alkanes present in the fuel. This behavior applies to jet fuels derived from alternate fossil fuel resources, such as shale oil, coal, and tar sands, as well as those derived from petroleum. In general, jet fuels from shale oil have the highest and those from coal the lowest n-alkane content. The origin of these n-alkanes in the amounts observed, especially in shale-derived fuels, is not readily explained on the basis of literature information. Studies of the processes, particularly the ones involving thermal stress, used to produce these fuels are needed to define how the n-alkanes form from larger molecules. The information developed will significantly contribute to the selection of processes and refining techniques for future fuel production from shale oil. Carbon-13 nmr studies indicate that oil shale rock contains many long unbranched straight chain hydrocarbon groups. The shale oil derived from the rock also gives indication of considerable straight chain material with large peaks at 14, 23, 30, and 32 ppM in the C-13 nmr spectrum. Previous pyrolysis studies stressed fractions of shale crude oil residua, measured the yields of JP-5, and determined the content of potential n-alkanes in the JP-5 distillation range (4). In this work, a shale crude oil vacuum distillate (Paraho) was separated into three chemical fractions. The fractions were then subjected to nmr analysis to estimate the potential for n-alkane production and to pyrolysis studies to determine an experimental n-alkane yield.

Strengthening the applicability of self-heating retorting process to oil shale via co-retorting  

Science Journals Connector (OSTI)

Abstract Recently a facile low-energy-input retorting route but without marked loss in the shale-oil yield is developed, which is achieved by a self-heating effect, that is, spontaneously increasing retorting temperature in the absence of external heat provision (Guo et al., 2013, 2014). In this work, the applicability of self-heating retorting (SHR) process to three Chinese oil shales from different places (i.e., Longkou, Huadian and Fushun) is studied. Of these three oil shales, Fushun oil shale is associated with coal and was previously abandoned during coal mining due to its not high kerogen or oil content. The results show that it’s hard for Fushun oil shale to obtain satisfying self-heating effect, while Longkou or Huadian oil shale with higher kerogen or oil content shows satisfactory SHR. However, by adding suitable amounts of Longkou or Huadian oil shale into Fushun oil shale, a satisfying self-heating effect can be obtained as well. Thus, the relatively low-grade Fushun oil shale can also be well utilized to produce shale oil via this facile SHR route. Moreover, to utilize Fushun oil shale with a greener SHR process, the process can be performed by co-retorting Fushun oil shale with pine needles, a kind of renewable biomass. This finding also provides a new starting point for exploring plentiful biomass resources to utilize low-grade oil shale to produce oil in the future work.

Late-Middle to Late Devonian (Givetian-Famennian) tectonic and stratigraphic history of central Kentucky  

SciTech Connect (OSTI)

Earliest Givetian deposition in central Kentucky is represented in upper parts of the Boyle and Sellersburg formations and reflects marginal-marine to shallow-marine carbonate deposition at the end of the second tectophase of the Acadian orogeny. Inception of the third tectophase of the Acadian orogeny in the area is reflected by a disconformity or angular unconformity between the Boyle and New Albany formations, by reactivation of faults on the Kentucky river and related fault zones, and by concurrent graben formation. Succeeding late Givetian deposition is represented by the equivalent Portwood and Blocher members of the New Albany. The Portwood represents localized deposition of dolomitic breccias and black shales in grabens and half grabens, paleogeographically manifest as a series of restricted coastal lagoons and estuaries in central and east-central Kentucky. In contrast, dolomitic, Blocher black shales in west-central kentucky, beyond the effects of faulting, reflect more open, platform-lagoonal conditions. Both units are carbonate rick, contain a sparse benthic fauna, and had local sources of sediment. By latest Givetian or earliest Frasnian, local basins were largely filed, and when local sediment sources were inundated by transgression, sediment starvation, represented by a major lag zone or bone bed, ensued throughout central Kentucky, while black- and gray-shale deposition continued in deeper parts of the Illinois and Appalachian basins. During the Frasnian and early Famennian, as subsidence and transgression continued, deeper water gray- and black-shale units from the Appalachian and Illinois basins slowly onlapped the Cincinnati Arch area of central Kentucky; black shales in these units are fissile and lack both carbonates and benthic fauna. At the Devonian-Mississippian transition, however, a locally developed unconformity and structurally related erosion probably reflect inception of the fourth and final tectophase of the Acadian orogeny.

Bakken and other Devonian-Mississippian petroleum source rocks, northern Rocky Mtns.-Williston basin: Depositional and burial history and maturity estimations  

SciTech Connect (OSTI)

The three-member Devonian-Mississippian Bakken-Exshaw organic-rich shaly facies is widely distributed in the northern U.S. and southern Canadian Cordillera. Equivalent facies are also present as far south as Utah and Nevada. Paleogeographically, these rocks thin markedly or pinchout to the west approximately along the Devonian-Mississippian carbonate reef-mound belt of the Cordilleran shelf margin. Although these rocks reach maximum organic richness approximately at the Devonian-Carboniferous transition, similar but somewhat less organic-rich Bakken-like beds are also present in underlying Upper Devonian and overlying Lower Carboniferous carbonate depositional cycles. At least ten cycles are identified in the underlying Duperow and Jefferson Formations, characterized by basal organic-rich Bakken-like shale or shaly carbonate that grades upward into carbonate mound or reefal beds, overlain by evaporite or solution breccia. Cycles in the overlying Lodgepole and Mission Canyon Formations, as many as 10-12 in number, are similar except that the carbonates are composed of algal-oolith, crinoid, or mixed skeletal beds, and end-cycle evaporitic units are less prevalent in the lower cycles. These dark shaly beds are the most important source of hydrocarbon reserves in Montana and the Williston basin. Maximum net thickness of the Devonian-Mississippian organic-rich facies is in the Williston basin. However, variable thicknesses of these potential source rocks is present in parts of Montana as far west as the thrust belt. Burial history studies suggest that in some areas these rocks are probably thermally immature. However, in much of the area original burial depths are sufficient for them to reach the thermally mature stage, and therefore are of importance to further exploration efforts in the Devonian-Mississippian Madison-Duperow-Jefferson Formations.

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

SciTech Connect (OSTI)

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

Stratigraphic distribution of paleozoic nonmarine ostracoda devonian  

Science Journals Connector (OSTI)

Publisher Summary Ostracoda of Leperditicopida-type have been reported to occur in nonmarine, probably fluvial, deposits in the Upper Devonian Catskill “redbed” magnafacies of New York. Ostracodes generally considered to be nonmarine were recorded in the Devonian of southern China—that is, Carbonita lentiforma Shi, 1964; and of the Russian Platform—that is, Carbonita lipetzkensis Zannina, 1960. Nonmarine Ostracoda were recorded from the Bramwell member of the Bluestone Formation in West Virginia and Virginia by Sohn. The upper part of the Humboldt Formation in northeastern Nevada is represented by Pactolocypris laevis; the middle Humboldt by Cypricercus toanoensis, C. hunterensis, Pactolocypris suborbicularis attenuatus, Eucypris ornatoides elongata, E. microreticulata, and Heterocypris blairensis; the lower Humboldt by Pactolocypris suborbicularis and Cypricercus palisadensis. Both the Esmeralda Formation of west-central Nevada and the Humboldt are dated as Miocene, but only three ostracode species occur in both formations based on present knowledge. About 35 ostracode species have been recorded from the Esmeralda Formation and its equivalents in Esmeralda, Mineral, and Nye Counties, western Nevada.

History and some potentials of oil shale cement  

SciTech Connect (OSTI)

The utilization of oil shale as a cement component is discussed. It was investigated in America and Europe during World War I. Additional development occurred in Western Europe, Russia, and China during the 1920s and 1930s. World War II provided further development incentives and a relatively mature technology was in place in Germany, Russia, and China prior to 1980. The utilization of oil shale in cement has taken a number of different paths. One approach has been to utilize the energy in the oil shale as the principal source for the cement plant and to use the combusted shale as a minor constituent of the plant's cement product. A second approach has been to use the combusted shale as a class C or cementitious fly-ash component in portland cement concrete. Other approaches utilizing eastern oil shale have been to use the combusted oil shale with additives as a specialty cement, or to cocombust the oil shale with coal and utilize the sulfur-rich combustion product.

Maintenance of high TDS in pore waters above the New Albany Shale of the Illinois Basin  

SciTech Connect (OSTI)

The TDS content of interstitial waters above the Upper Devonian New Albany Shale of the Illinois Basin, mostly sodium and chloride, increases at an average rate of 15 wt%km[sup [minus]1]. Roughly 200 My have elapsed since the youngest marine rocks of wide horizontal extent [Pennsylvania] were deposited. Regardless of the original brine-forming mechanism, the maintenance of high TDS for such a long time span is problematic because upward diffusion above the New Albany Shale should have lowered TDS if no salt dissolved above the New Albany Shale. Groundwater flow at even small rates would have lowered TDS faster than the process of diffusion alone. Calculations which take into account the effects of vertical diffusion show that the present-day salinity gradient of waters above the New Albany Shale can be explained if: (1) the salinity gradient 200 My b.p. was at least thrice as high as at the present, or (2) salt dissolved above the New Albany Shale at an average rate of about 12 m of halite column over 200 My. The code PORFLOW was used to simulate flushing of brines in a generic basin 500 km wide, 1.5 km deep [the maximum depth of the New Albany Shale], with a low basin-wide topographic gradient of 0.06%.

Characterization of interim reference shales  

SciTech Connect (OSTI)

Measurements have been made on the chemical and physical properties of two oil shales designated as interim reference oil shales by the Department of Energy. One oil shale is a Green River Formation, Parachute Creek Member, Mahogany Zone Colorado oil shale from the Anvil Points mine and the other is a Clegg Creek Member, New Albany shale from Kentucky. Material balance Fischer assays, kerogen concentrates, carbon aromaticities, thermal properties, and bulk mineralogic properties have been determined for the oil shales. The measured properties of the interim reference shales are comparable to results obtained from previous studies on similar shales. The western interim reference shale has a low carbon aromaticity, high Fischer assay conversion to oil, and a dominant carbonate mineralogy. The eastern interim reference shale has a high carbon aromaticity, low Fischer assay conversion to oil, and a dominant silicate mineralogy. Chemical and physical properties, including ASTM distillations, have been determined for shale oils produced from the interim reference shales. The distillation data were used in conjunction with API correlations to calculate a large number of shale oil properties that are required for computer models such as ASPEN. The experimental determination of many of the shale oil properties was beyond the scope of this study. Therefore, direct comparison between calculated and measured values of many properties could not be made. However, molecular weights of the shale oils were measured. In this case, there was poor agreement between measured molecular weights and those calculated from API and other published correlations. 23 refs., 12 figs., 15 tabs.

Technology experience and economics of oil shale mining in Estonia  

SciTech Connect (OSTI)

The exhaustion of fuel-energy resources became an evident problem of the European continent in the 1960s. Careful utilization of their own reserves of coal, oil, and gas (Germany, France, Spain) and assigned shares of imports of these resources make up the strategy of economic development of the European countries. The expansion of oil shale utilization is the most topical problem. The experience of mining oil shale deposits in Estonia and Russia, in terms of the practice and the economic results, is reviewed in this article. The room-and-pillar method of underground mining and the open-cut technology of clearing the ground ensure the fertility of a soil. The economics of underground and open pit oil shale mines is analyzed in terms of natural, organizational, and technical factors. These analyses are used in the planning and management of oil shale mining enterprises. The perspectives of the oil shale mining industry of Estonia and the economic expediency of multiproduction are examined. Recommendations and guidelines for future industrial utilization of oil shale are given in the summary.

Process for oil shale retorting  

DOE Patents [OSTI]

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

Oil shale retort apparatus  

DOE Patents [OSTI]

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

Oil shale: Technology status report  

SciTech Connect (OSTI)

This report documents the status of the US Department of Energy's (DOE) Oil Shale Program as of the end of FY 86. The report consists of (1) a status of oil shale development, (2) a description of the DOE Oil Shale Program, (3) an FY 86 oil shale research summary, and (4) a summary of FY 86 accomplishments. Discoveries were made in FY 86 about the physical and chemical properties and behavior of oil shales, process chemistry and kinetics, in situ retorting, advanced processes, and the environmental behavior and fate of wastes. The DOE Oil Shale Program shows an increasing emphasis on eastern US oil shales and in the development of advanced oil shale processing concepts. With the award to Foster Wheeler for the design of oil shale conceptual plants, the first step in the development of a systems analysis capability for the complete oil shale process has been taken. Unocal's Parachute Creek project, the only commercial oil shale plant operating in the United States, is operating at about 4000 bbl/day. The shale oil is upgraded at Parachute Creek for input to a conventional refinery. 67 refs., 21 figs., 3 tabs.

Solar retorting of oil shale  

DOE Patents [OSTI]

An apparatus and method for retorting oil shale using solar radiation. Oil shale is introduced into a first retorting chamber having a solar focus zone. There the oil shale is exposed to solar radiation and rapidly brought to a predetermined retorting temperature. Once the shale has reached this temperature, it is removed from the solar focus zone and transferred to a second retorting chamber where it is heated. In a second chamber, the oil shale is maintained at the retorting temperature, without direct exposure to solar radiation, until the retorting is complete.

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

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

SciTech Connect (OSTI)

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

Influence of chemical characterization of oil shale solids on understanding water quality impacts  

SciTech Connect (OSTI)

Synfuels technologies will yield products and effluents that are a function of the raw material being processed and the process variables. Chemical and mineralogic characterization of solids generated in synfuels production provide valuable insight into health and environmental impacts associated with synfuels processing (coal liquefaction or gasification and shale oil extraction). This report deals with considerations relating to leachate generation from solid wastes, but the suggested research approach is applicable to understanding the nature and extent of all effluents from synfuels operations. Solid characterization studies of one raw shale core and two spent shale cores from Occidental Oil Shale, Inc.'s Logan Wash site are described. These data are used to determine the effect of processing on the shale solids and also to evaluate a variety of water quality issues associated with in situ processing. The importance of solid characterization studies in developing an understanding of effluent composition and behavior and subsequently defining environmental impacts is described.

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

SciTech Connect (OSTI)

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

Gas sales starting from Indiana`s fractured New Albany shale  

SciTech Connect (OSTI)

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

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

The heated mixture then passes through a pyrolyzer stage where it resides for a sufficient time for complete pyrolysis to occur. The spent shale from the pyrolyzer is recirculated through a burner stage where the residual char is burned to heat the shale which then enters the mixer stage.

Investigation and development of alternative methods for shale oil processing and analysis. Final technical report, October 1979--April 1983  

SciTech Connect (OSTI)

Oil shale, a carbonaceous rock which occurs abundantly in the earth`s crust, has been investigated for many years as an alternate source of fuel oil. The insoluble organic matter contained in such shales is termed {open_quotes}Kerogen{close_quotes} from the Greek meaning oil or oil forming. The kerogen in oil shale breaks down into oil-like products when subjected to conditions simulating destructive distillation. These products have been the subject of extensive investigations by several researchers and many of the constituents of shale oil have been identified. (1) Forsman (2) estimates that the kerogen content of the earth is roughly 3 {times} 10{sup 15} tons as compared to total coal reserves of about 5 {times} 10{sup 12}. Although the current cost per barrel estimate for commercial production of shale oil is higher than that of fossil oil, as our oil reserves continue to dwindle, shale oil technology will become more and more important. When oil shale is heated, kerogen is said to undergo chemical transformation to usable oil in two steps (3): Kerogen (in oil shale) 300-500{degrees}C bitumen. Crude shale oil and other products. The crude shale oil so obtained differs from fossil oil in that: (1) kerogen is thought to have been produced from the aging of plant matter over many years; (2) shale oil has a higher nitrogen content than fossil oil; (3) non-hydrocarbons are present to a much greater extent in shale oil; and (4) the hydrocarbons in shale oil are much more unsaturated than those in fossil oil (petroleum).

Ion chromatographic analysis of oil shale leachates  

SciTech Connect (OSTI)

In the present work an investigation of the use of ion chromatography to determine environmentally significant anions present in oil shale leachates was undertaken. Nadkarni et al. have used ion chromatography to separate and quantify halogen, sulfur and nitrogen species in oil shales after combustion in a Parr bomb. Potts and Potas used ion chromatography to monitor inorganic ions in cooling tower wastewater from coal gasification. Wallace and coworkers have used ion chromatography to determine anions encountered in retort wastewaters. The ions of interest in this work were the ions of sulfur oxides including sulfite (SO{sub 3}{sup 2{minus}}), sulfate (SO{sub 4}{sup 2{minus}}), thiosulfate (S{sub 2}O{sub 3}{sup 2{minus}}), dithionite (S{sub 2}O{sub 4}{sup 2{minus}}), dithionate (S{sub 2}O{sub 6}{sup 2{minus}}), peroxyodisulfate (S{sub 2}O{sub 8}{sup 2{minus}}), and tetrathionate (S{sub 4}O{sub 6}{sup 2{minus}}), and thiocyanate (SCN{sup {minus}}), sulfide (S{sup 2{minus}}) hydrosulfide (HS{sup {minus}}), cyanide (CN{sup {minus}}), thiocyanate (SCN{sup {minus}}), and cyanate (OCN{sup {minus}}).

Hydration and strength development of binder based on high-calcium oil shale fly ash  

SciTech Connect (OSTI)

The properties of high-calcium oil shale fly ash and low-calcium coal fly ash, which are produced in Israeli power stations, were investigated. High-calcium oil shale fly ash was found to contain a great amount of CaO{sub free} and SO{sub 3} in the form of lime and anhydrite. Mixtures of high-calcium oil shale fly ash and low-calcium coal fly ash, termed fly ash binder, were shown to cure and have improved strength. The influence of the composition and curing conditions on the compressive strength of fly ash binders was examined. The microstructure and the composition of fly ash binder after curing and long-term exposure in moist air, water and open air conditions were studied. It was determined that ettringite is the main variable in the strength and durability of cured systems. The positive effect of calcium silicate hydrates, CSH, which are formed by interaction of high-calcium oil shale fly ash and low-calcium coal fly ash components, on the carbonation and dehydration resistance of fly ash binder in open air is pronounced. It was concluded that high-calcium oil shale fly ash with high CaO{sub free} and SO{sub 3} content can be used as a binder for building products.

Combustion of municipal solid wastes with oil shale in a circulating fluidized bed. Quarterly report, quarter ending 31 December 1994  

SciTech Connect (OSTI)

The test plan is designed to demonstrate that oil shale co-combusted with municipal solid waste (MSW) can reduce gaseous pollutants (SO{sub 2}, CO) to acceptable levels (90%+ reduction) and produce a cementitious ash which will, at a minimum, be acceptable in normal land fills. The small-scale combustion testing will be accomplished in a 6-in. circulating fluid bed combustor (CFBC) at Hazen Research Laboratories. This work will be patterned after the study the authors conducted in 1988 when coal and oil shale were co-combusted in a program sponsored by the Electric Power Research Institute. The specific purpose of the test program will be to: determine the required ratio of oil shale to MSW by determining the ratio of absorbent to pollutant (A/P); determine the effect of temperature and resident time in the reactor; and determine if kinetic model developed for coal/oil shale mixture is applicable.

Eastern shale hydroretorting  

SciTech Connect (OSTI)

The overall objective of the Bench-Scale Unit (BSU) test program was to determine the effects of major process variables on conversion of organic carbon, yields and properties of oil and gas and consumption of hydrogen for hydroretorting of a specific Indiana New Albany shale. A preliminary error-propagation analysis was performed to identify possible improvements in BSU measurements that could lead to better overall material and elemental balances. A list of additional potential sources of uncertainty (primarily due to the operating procedures used) was compiled. Based on the identification of these possible sources of uncertainty, additional equipment was ordered and installed and existing operating procedures and calculation methods were modified. The result was excellent overall material balance closures (100% +/- 1%).

The elastic anisotrophy of shales  

SciTech Connect (OSTI)

Shales constitute about 75% of the clastic fill sedimentary basins and have a decisive effect on fluid flow and seismic wave propagation because of their low permeability and anisotropic microstructure. The elastic stiffnesses of a shale with partially oriented clay particles is expressed in terms of the coefficients W(sub lmn) in an expansion of the clay-particle orientation distribution function in generalized Legendre functions. Application is made to the determination of the anellipticity of shales. For transverse isotrophy the anellipticity quantifies the deviation of the P wave slowness curve from an ellipse and is shown to depend on a single coefficient W(sub 400) in the expansion of the clay-particle orientation distribution function. If W(sub 400) is small, the anellipticity may be neglected, as is apparently the case for a near-surface late Tertiary shale studied by Winterstein and Paulson. Strongly aligned clay particles result in a positive value of W(sub 400) and a positive anellipticity, in agreement with the majority of the field measurements. However, less well ordered shales could have a significantly positive second moment W(sub 200) but only a small positive or even negative value of W(sub 400). For such shales the anellipticity would be small or negative despite a preferred alignment of clay particles in the bedding plane. Numerical examples of clay particle orientation distribution functions leading to zero or negative anellipticity are given.

Net thickness of the radioactive shale facies in the lower Olentangy shale (Hamilton group)  

SciTech Connect (OSTI)

The net thickness of radioactive shale is determined by first establishing a normal base line for each well based upon the gamma ray log response of shale units, such as the Bedford, Chagrin, and certain units within the Olentangy, observed to be fairly consistently radioactive. Radioactive shales are then defined as those shales having a gamma ray response 20 API units or more to the right of the shale base line.

Net thickness of the radioactive shale facies in the Cleveland member of the Ohio shale  

SciTech Connect (OSTI)

The net thickness of radioactive shale is determined by first establishing a normal base line for each well based upon the gamma ray log response of shale units, such as the Bedford, Chagrin, and certain units within the Olentangy, observed to be fairly consistently radioactive. Radioactive shales are then defined as those shales having a gamma ray response 20 API units or more to the right of the shale base line. The combined thickness of beds reaching the radioactive shale threshold value is reported as the net thickness of radioactive shale facies within the mapping unit.

Proof-of-Concept Oil Shale Facility Environmental Analysis Program  

SciTech Connect (OSTI)

The objectives of the Project are to demonstrate: (1) the Modified In- Situ (MIS) shale oil extraction process and (2) the application of CFBC technology using oil shale, coal and waste gas streams as fuels. The project will focus on evaluating and improving the efficiency and environmental performance of these technologies. The project will be modest by commercial standards. A 17-retort MIS system is planned in which two retorts will be processed simultaneously. Production of 1206-barrels per calendar day of raw shale oil and 46-megawatts of electricity is anticipated. West Virginia University coordinated an Environmental Analysis Program for the Project. Experts from around the country were retained by WVU to prepare individual sections of the report. These experts were exposed to all of OOSI`s archives and toured Tract C-b and Logan Wash. Their findings were incorporated into this report. In summary, no environmental obstacles were revealed that would preclude proceeding with the Project. One of the most important objectives of the Project was to verify the environmental acceptability of the technologies being employed. Consequently, special attention will be given to monitoring environmental factors and providing state of the art mitigation measures. Extensive environmental and socioeconomic background information has been compiled for the Tract over the last 15 years and permits were obtained for the large scale operations contemplated in the late 1970`s and early 1980`s. Those permits have been reviewed and are being modified so that all required permits can be obtained in a timely manner.

Oil shale technology. Final report  

SciTech Connect (OSTI)

This collaborative project with industrial participants studied oil shale retorting through an integrated program of fundamental research, mathematical model development and operation of a 4-tonne-per-day solid recirculation oil shale test unit. Quarterly, project personnel presented progress and findings to a Project Guidance Committee consisting of company representatives and DOE program management. We successfully operated the test unit, developed the oil shale process (OSP) mathematical model, evaluated technical plans for process scale up and determined economics for a successful small scale commercial deployment, producing premium motor fuel, specility chemicals along with electricity co-production. In budget negotiations, DOE funding for this three year CRADA was terminated, 17 months prematurely, as of October 1993. Funds to restore the project and continue the partnership have not been secured.

Jordan ships oil shale to China  

SciTech Connect (OSTI)

Jordan and China have signed an agreement to develop oil shale processing technology that could lead to a 200 ton/day oil shale plant in Jordan. China will process 1200 tons of Jordanian oil shale at its Fu Shun refinery. If tests are successful, China could build the demonstration plant in Jordan's Lajjun region, where the oil shale resource is estimated at 1.3 billion tons. China plans to send a team to Jordan to conduct a plant design study. A Lajjun oil shale complex could produce as much as 50,000 b/d of shale oil. An earlier 500 ton shipment of shale is said to have yielded promising results.

Transport and reduction of sulfate and immobilization of sulfide in marine black shales  

SciTech Connect (OSTI)

In fine-grained sediments in which the amount of reduced sulfur retained in stable phases substantially exceeds that present initially in pore waters, rates of sulfate reduction may have equaled or exceeded rates of sulfate transport, resulting in enrichment of [sup 34]S in pore waters and reduction products. Abundance and isotopic compositions of reduced sulfur compounds can be used to calculate the extent of sulfide retention and improve reconstructions of carbon-sulfur oxidation-reduction (redox) budgets. The Miocene Monterey Formation and Upper Devonian New Albany Shale represent distinct types of black shales that accumulated under different conditions of sulfate reduction. Our results suggest that the rate of sulfate reduction was controlled largely by mass transport in the Monterey and by the reduction process itself in the New Albany. Sulfide was more efficiently retained in the Monterey; thus each mole of sulfide in the New Albany represents a greater amount of sedimented organic carbon removed during sulfate reduction. 30 refs., 4 figs., 1 tab.

Clarification of C-S relationships of marine black shales using stable isotopic composition of reduced sulfur  

SciTech Connect (OSTI)

Carbon-sulfur relationships are compared for the Miocene Monterey Formation (Santa Maria Basin, California) and the Upper Devonian New Albany Shale (Illinois Basin, Indiana). In both formations, C-S concentrations covary for samples with the lower to more intermediate organic carbon concentrations and become invariant at higher organic carbon concentrations. While the similarity of these relationships in Monterey and New Albany suggest sulfur diagenesis occurred in similar depositional environments, sulfur isotopic data clearly indicate differences in the depositional environments. In the Monterey, the most organic-rich laminated shales are characterized by isotopic enrichment of reduced S and low S ratios and indicate that sulfate reduction occurred under sulfate-limited conditions within the sediments. In the New Albany, organic-rich laminated shales exhibit isotopic depletion of reduced S coupled with low S[sub reduced]/C[sub org] and suggest sulfur diagenesis occurred under euxinic conditions. These data show that in the absence of sulfur isotopic data, misleading conclusions concerning depositional environments can be made when using C-S plots and the traditional interpretations that are associated with these types of plots.

Conversion characteristics of 10 selected oil shales  

SciTech Connect (OSTI)

The conversion behavior of 10 oil shale from seven foreign and three domestic deposits has been studied by combining solid- and liquid-state nuclear magnetic resonance (NMR) measurements with material balance Fischer assay conversion data. The extent of aromatization of aliphatic carbons was determined. Between zero and 42% of the raw shale aliphatic carbon formed aromatic carbon during Fischer assay. For three of the shales, there was more aromatic carbon in the residue after Fisher assay than in the raw shale. Between 10 and 20% of the raw shale aliphatic carbons ended up as aliphatic carbons on the spent shale. Good correlations were found between the raw shale aliphatic carbon and carbon in the oil and between the raw shale aromatic carbon and aromatic carbon on the spent shale. Simulated distillations and molecular weight determinations were performed on the shale oils. Greater than 50% of the oil consisted of the atmospheric and vacuum gas oil boiling fractions. 14 refs., 15 figs., 1 tab.

Production of hydrogen from oil shale  

SciTech Connect (OSTI)

A process for production of hydrogen from oil shale fines by direct introduction of the oil shale fines into a fluidized bed at temperatures about 1200/sup 0/ to about 2000/sup 0/ F. to obtain rapid heating of the oil shale. The bed is fluidized by upward passage of steam and oxygen, the steam introduced in the weight ratio of about 0.1 to about 10 on the basis of the organic carbon content of the oil shale and the oxygen introduced in less than the stoichiometric quantity for complete combustion of the organic carbonaceous kerogen content of the oil shale. Embodiments are disclosed for heat recovery from the spent shale and heat recovery from the spent shale and product gas wherein the complete process and heat recovery is carried out in a single reaction vessel. The process of this invention provides high conversion of organic carbon component of oil shale and high production of hydrogen from shale fines which when used in combination with a conventional oil shale hydroconversion process results in increased overall process efficiency of greater than 15 percent.

Shale Oil Value Enhancement Research  

SciTech Connect (OSTI)

Raw kerogen oil is rich in heteroatom-containing compounds. Heteroatoms, N, S & O, are undesirable as components of a refinery feedstock, but are the basis for product value in agrochemicals, pharmaceuticals, surfactants, solvents, polymers, and a host of industrial materials. An economically viable, technologically feasible process scheme was developed in this research that promises to enhance the economics of oil shale development, both in the US and elsewhere in the world, in particular Estonia. Products will compete in existing markets for products now manufactured by costly synthesis routes. A premium petroleum refinery feedstock is also produced. The technology is now ready for pilot plant engineering studies and is likely to play an important role in developing a US oil shale industry.

Underground Coal Thermal Treatment  

SciTech Connect (OSTI)

The long-term objective of this work is to develop a transformational energy production technology by insitu thermal treatment of a coal seam for the production of substitute natural gas (SNG) while leaving much of the coalâ??s carbon in the ground. This process converts coal to a high-efficiency, low-GHG emitting gas fuel. It holds the potential of providing environmentally acceptable access to previously unusable coal resources. This topical report discusses the development of experimental capabilities, the collection of available data, and the development of simulation tools to obtain process thermo-chemical and geo-thermal parameters in preparation for the eventual demonstration in a coal seam. It also includes experimental and modeling studies of CO{sub 2} sequestration. Efforts focused on: â?¢ Constructing a suite of three different coal pyrolysis reactors. These reactors offer the ability to gather heat transfer, mass transfer and kinetic data during coal pyrolysis under conditions that mimic in situ conditions (Subtask 6.1). â?¢ Studying the operational parameters for various underground thermal treatment processes for oil shale and coal and completing a design matrix analysis for the underground coal thermal treatment (UCTT). This analysis yielded recommendations for terms of targeted coal rank, well orientation, rubblization, presence of oxygen, temperature, pressure, and heating sources (Subtask 6.2). â?¢ Developing capabilities for simulating UCTT, including modifying the geometry as well as the solution algorithm to achieve long simulation times in a rubblized coal bed by resolving the convective channels occurring in the representative domain (Subtask 6.3). â?¢ Studying the reactive behavior of carbon dioxide (CO{sub 2}) with limestone, sandstone, arkose (a more complex sandstone) and peridotite, including mineralogical changes and brine chemistry for the different initial rock compositions (Subtask 6.4). Arkose exhibited the highest tendency of participating in mineral reactions, which can be attributed to the geochemical complexity of its initial mineral assemblage. In experiments with limestone, continuous dissolution was observed with the release of CO{sub 2} gas, indicated by the increasing pressure in the reactor (formation of a gas chamber). This occurred due to the lack of any source of alkali to buffer the solution. Arkose has the geochemical complexity for permanent sequestration of CO{sub 2} as carbonates and is also relatively abundant. The effect of including NH{sub 3} in the injected gas stream was also investigated in this study. Precipitation of calcite and trace amounts of ammonium zeolites was observed. A batch geochemical model was developed using Geochemists Workbench (GWB). Degassing effect in the experiments was corrected using the sliding fugacity model in GWB. Experimental and simulation results were compared and a reasonable agreement between the two was observed.

The structure and reactivity of a low-sulfur lacustrine oil shale (Colorado U.S.A.) compared with those of a high-sulfur marine oil shale (Julia Creek, Queensland, Australia)  

Science Journals Connector (OSTI)

Abstract Oil shales from two different continents (Australia and North America) of different ages (100 and 40 million years) and origins (one marine, one lacustrine) have been reacted in the range 355–425 °C under H2 or N2 for 1 or 5 h with or without the addition of catalyst. The shales differed in S content, and the nature of the mineral matter, but both had high atomic H/C ratios. The overall reactivity of the two shales was similar and high yields of soluble products could be obtained under relatively mild conditions with only small CO2 yields, but the temperature dependence of reactivity and the effect of potential catalysts differed markedly. Increasing the temperature and time led to increases in conversion but of different extents. Substituting H2 for N2 led to a large increase to conversion for the lower-atomic-H/C ratio marine oil shale. The \\{CH2Cl2\\} solubles from the marine oil shale showed a larger range of compounds than those from the lacustrine oil shale which resembled the \\{CH2Cl2\\} solubles from torbanite, a coal-like material derived from lacustrine algae.

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

Characterization of DOE reference oil shales: Mahogany Zone, Parachute Creek Member, Green River Formation Oil Shale, and Clegg Creek Member, New Albany Shale  

SciTech Connect (OSTI)

Measurements have been made on the chemical and physical properties of two oil shales designated as reference oil shales by the Department of Energy. One oil shale is a Green River Formation, Parachute Creek Member, Mahogany Zone Colorado oil shale from the Exxon Colony mine and the other is a Clegg Creek Member, New Albany shale from Kentucky. Material balance Fischer assays, carbon aromaticities, thermal properties, and bulk mineralogic properties have been determined for the oil shales. Kerogen concentrates were prepared from both shales. The measured properties of the reference shales are comparable to results obtained from previous studies on similar shales. The western reference shale has a low carbon aromaticity, high Fischer assay conversion to oil, and a dominant carbonate mineralogy. The eastern reference shale has a high carbon aromaticity, low Fischer assay conversion to oil, and a dominant silicate mineralogy. Chemical and physical properties, including ASTM distillations, have been determined for shale oils produced from the reference shales. The distillation data were used in conjunction with API correlations to calculate a large number of shale oil properties that are required for computer models such as ASPEN. There was poor agreement between measured and calculated molecular weights for the total shale oil produced from each shale. However, measured and calculated molecular weights agreed reasonably well for true boiling point distillate fractions in the temperature range of 204 to 399/sup 0/C (400 to 750/sup 0/F). Similarly, measured and calculated viscosities of the total shale oils were in disagreement, whereas good agreement was obtained on distillate fractions for a boiling range up to 315/sup 0/C (600/sup 0/F). Thermal and dielectric properties were determined for the shales and shale oils. The dielectric properties of the reference shales and shale oils decreased with increasing frequency of the applied frequency. 42 refs., 34 figs., 24 tabs.

Method for forming an in-situ oil shale retort in differing grades of oil shale  

SciTech Connect (OSTI)

An in-situ oil shale retort is formed in a subterranean formation containing oil shale. The formation comprises at least one region of relatively richer oil shale and another region of relatively leaner oil shale. According to one embodiment, formation is excavated from within a retort site for forming at least one void extending horizontally across the retort site, leaving a portion of unfragmented formation including the regions of richer and leaner oil shale adjacent such a void space. A first array of vertical blast holes are drilled in the regions of richer and leaner oil shale, and a second array of blast holes are drilled at least in the region of richer oil shale. Explosive charges are placed in portions of the blast holes in the first and second arrays which extend into the richer oil shale, and separate explosive charges are placed in portions of the blast holes in the first array which extend into the leaner oil shale. This provides an array with a smaller scaled depth of burial (sdob) and closer spacing distance between explosive charges in the richer oil shale than the sdob and spacing distance of the array of explosive charges in the leaner oil shale. The explosive charges are detonated for explosively expanding the regions of richer and leaner oil shale toward the horizontal void for forming a fragmented mass of particles. Upon detonation of the explosive, greater explosive energy is provided collectively by the explosive charges in the richer oil shale, compared with the explosive energy produced by the explosive charges in the leaner oil shale, resulting in comparable fragmentation in both grades of oil shale.

Origin of coal seam structures, Sullivan County, Indiana  

SciTech Connect (OSTI)

Structures of Pennsylvanian coal seams in Sullivan County, Indiana, reflect deeper structural components, of which regional dip is dominant. Other components of structure result form differential compaction. The effects of these components are characterized by their closure, size, shape, and orientation. (1) The Mississippian unconformity surface is characterized by parallel valley with up to 300 ft (91 m) of local relief. (2) The composite lower Pennsylvanian section below the Seelyville Coal has variable sandstone content. Some paleovalleys are filled with multistory sandstones, and others with claystone. (3) Silurian pinnacle reefs from small, circular features with a diameter of 1 to 2 mi (1.5 to 3 km) and closures of 25 tio 50 ft (8 to 15 m) on Pennsylvanian coal seams, 50 ft (15 m) on the Aux Vases Shale, and 150 ft (45 m) on the New Albany Shale. (4) The distributions and standard deviations of thicknesses, dips, and grain size of the sedimentary rocks between the coal seams demonstrate that seams above the Seelyville Coal were deposited in parallel and have concordant modern structures. Specific facies between seams have limited influence on the overall structure. Coal structures in the Illinois basin can be defined by a drilling program that penetrates only 150 ft (45 m) of Pennsylvanian strata. Below the Seelyville Coal, units examined demonstrate basin-margin convergence.

Fluidized bed retorting of eastern oil shale  

SciTech Connect (OSTI)

This topical report summarizes the conceptual design of an integrated oil shale processing plant based on fluidized bed retorting of eastern New Albany oil shale. This is the fourth design study conducted by Foster Wheeler; previous design cases employed the following technologies: Fluidized bed rotating/combustion of Colorado Mahogany zone shale. An FCC concept of fluidized bed retorting/combustion of Colorado Mahogany zone shale. Directly heated moving vertical-bed process using Colorado Mahogany zone shale. The conceptual design encompasses a grassroots facility which processes run-of-mine oil shale into a syncrude oil product and dispose of the spent shale solids. The plant has a nominal capacity of 50,000 barrels per day of syncrude product, produced from oil shale feed having a Fischer Assay of 15 gallons per ton. Design of the processing units was based on non-confidential published information and supplemental data from process licensors. Maximum use of process and cost information developed in the previous Foster Wheeler studies was employed. The integrated plant design is described in terms of the individual process units and plant support systems. The estimated total plant investment is detailed by plant section and estimates of the annual operating requirements and costs are provided. In addition, process design assumptions and uncertainties are documented and recommendations for process alternatives, which could improve the overall plant economics, are discussed. 12 refs., 17 figs., 52 tabs.

Coal extraction  

SciTech Connect (OSTI)

Coal is extracted using a mixed solvent which includes a substantially aromatic component and a substantially naphthenic component, at a temperature of 400/sup 0/ to 500/sup 0/C. Although neither component is an especially good solvent for coal by itself, the use of mixed solvent gives greater flexibility to the process and offers efficiency gains.

LLNL oil shale project review: METC third annual oil shale contractors meeting  

SciTech Connect (OSTI)

The Lawrence Livermore National Laboratory combines laboratory and pilot-scale experimental measurements with mathematical modeling of fundamental chemistry and physics to provide a technical base for evaluating oil shale retorting alternatives. Presented herein are results of four research areas of interest in oil shale process development: Recent Progress in Solid-Recycle Retorting and Related Laboratory and Modeling Studies; Water Generation During Pyrolysis of Oil Shale; Improved Analytical Methods and Measurements of Rapid Pyrolysis Kinetics for Western and Eastern Oil Shale; and Rate of Cracking or Degradation of Oil Vapor In Contact with Oxidized Shale. We describe operating results of a 1 tonne-per-day, continuous-loop, solid-recycle, retort processing both Western And Eastern oil shale. Sulfur chemistry, solid mixing limits, shale cooling tests and catalyst addition are all discussed. Using a triple-quadrupole mass spectrometer, we measure individual species evolution with greater sensitivity and selectivity. Herein we discuss our measurements of water evolution during ramped heating of Western and Eastern oil shale. Using improved analytical techniques, we determine isothermal pyrolysis kinetics for Western and Eastern oil shale, during rapid heating, which are faster than previously thought. Finally, we discuss the rate of cracking of oil vapor in contact with oxidized shale, qualitatively using a sand fluidized bed and quantitatively using a vapor cracking apparatus. 3 refs., 4 figs., 1 tab.

METC research on coal-fired diesels  

SciTech Connect (OSTI)

The METC in-house Coal-Fueled Diesel Research project is part of the overall DOE effort to develop a technology base for diesel engines capable of operating on coal, shale oil or low-cost coal-derived fuels. The in-house effort started in 1985 as a test-bed for coal-derived liquid fuels and will end this fiscal year with the successful completion of METC`s diesel R&D program. Currently METC in-house research and development efforts focus on pilot chamber combustion in METC`s coal-water slurry (CWS) fueled diesel engine. A novel pilot chamber for a direct-injected, coal-fueled diesel engine has been designed and is being tested in METC`s single cylinder research diesel engine. The pilot chamber configuration allows for operation at extended load and speed conditions using 100 percent CWS and no other pilot fuel. The concept involves the use of a small volume chamber exterior to the main cylinder in which approximately 5 percent of the total fuel energy at full load conditions is injected. Lower NO{sub X} levels may be obtained due to leaner burning as well as broader stable performance using only CWS fuel.

Macrodispersion in sand-shale sequences  

SciTech Connect (OSTI)

Macrodispersion in sand-shale sequences is investigated by a series of numerical tracer tests. Hydraulic conductivity is modeled as a binary, spatially correlated random function. Realizations of the random conductivity field are simulated on a nodal grid discretizing the heterogeneous formation. Corresponding realizations of the random velocity field are obtained by solving the equation for saturated steady state flow. Particle tracking, with flux-weighted tracer injection and detection, is used to generate experimental residence time distributions (RTDs). Moments of the RTD are used to characterize longitudinal tracer spreading. Results show that macrodispersive transport in sand-shale sequences cannot be represented by a Fickian model. RTDs display a bimodal structural caused by the fast arrival of particles traveling along preferential sandstone and shale. The relative importance of channeling and tortuous flow transport mechanisms is determined by sand-shale conductivity contrast, shale volume fraction, and conductivity spatial correlation structure. Channeling is promoted by high conductivity contrasts, low shale fractions, and flow parallel to bedding in anisotropic media. Low contrasts, high shale fractions, and flow perpendicular to bedding act to break up channels and to enhance tracer spreading.

In situ retorting or oil shale  

SciTech Connect (OSTI)

An improved method of in situ retorting of oil shale wherein a cavern of crushed shale is created within an oil shale deposit, preferably by igniting a powerful explosion within the oil shale deposit, thereby creating a localized area or cavern of rubblized oil shale. Combustion gases are injected into the bottom of this cavern and particulate material, preferably a cracking catalyst, is deposited into a void at the top of the cavern and allowed to trickle down and fill the voids in the rubblized cavern. The oil shale is ignited at the bottom of the cavern and a combustion zone proceeds upwardly while the particulate material is caused by gas flow to percolate downwardly. A fluidized bed of particulate material is thereby formed at the combustion zone providing a controlled, evelny advancing combustion zone. This, in turn, efficiently retorts oil shale, provides increased recovery of hydrocarbon while ismultaneously producing a catalytically cracked volatile, high octane gasoline exiting from the top of the retort.

Adsorption of pyridine by combusted oil shale  

SciTech Connect (OSTI)

Large volumes of solid waste material will be produced during the commercial production of shale oil. An alternative to the disposal of the solid waste product is utilization. One potential use of spent oil shale is for the stabilization of hazardous organic compounds. The objective of this study was to examine the adsorption of pyridine, commonly found in oil shale process water, by spent oil shale. The adsorption of pyridine by fresh and weathered samples of combusted New Albany Shale and Green River Formation oil shale was examined. In general, pyridine adsorption can be classified as L-type and the isotherms modeled with the Langmuir and Freundlich equations. For the combusted New Albany Shale, weathering reduced the predicted pyridine adsorption maximum and increased the amount of pyridine adsorption maximum. The pyridine adsorption isotherms were similar to those mathematically described by empirical models, the reduction in solution concentrations of pyridine was generally less than 10 mg L{sup {minus}1} at an initial concentration of 100 mg L{sup {minus}1}. 31 refs., 3 figs., 3 tabs.

Nitrogen chemistry during oil shale pyrolysis  

SciTech Connect (OSTI)

Real time evolution of ammonia (NH{sub 3}) and hydrogen cyanide (HCN), two major nitrogen-containing volatiles evolved during oil shale pyrolysis, was measured by means of a mass spectrometer using chemical ionization and by infrared spectroscopy. While the on-line monitoring of NH{sub 3} in oil shale pyrolysis games was possible by both techniques, HCN measurements were only possible by IR. We studied one Green River Formation oil shale and one New Albany oil shale. The ammonia from the Green River oil shale showed one broad NH{sub 3} peak maximizing at a high temperature. For both oil shales, most NH{sub 3} evolves at temperatures above oil-evolving temperature. The important factors governing ammonia salts such as Buddingtonite in Green River oil shales, the distribution of nitrogen functional groups in kerogen, and the retorting conditions. The gas phase reactions, such as NH{sub 3} decomposition and HCN conversion reactions, also play an important role in the distribution of nitrogen volatiles, especially at high temperatures. Although pyrolysis studies of model compounds suggests the primary nitrogen product from kerogen pyrolysis to be HCN at high temperatures, we found only a trace amount of HCN at oil-evolving temperatures and none at high temperatures (T {gt} 600{degree}C). 24 refs., 6 figs., 2 tabs.

Gasification characteristics of eastern oil shale  

SciTech Connect (OSTI)

The Institute of Gas Technology (IGT) is evaluating the gasification characteristics of Eastern oil shales as a part of a cooperative agreement between the US Department of Energy and HYCRUDE Corporation to expand the data base on moving-bed hydroretorting of Eastern oil shales. Gasification of shale fines will improve the overall resource utilization by producing synthesis gas or hydrogen needed for the hydroretorting of oil shale and the upgrading of shale oil. Gasification characteristics of an Indiana New Albany oil shale have been determined over temperature and pressure ranges of 1600 to 1900/sup 0/F and 15 to 500 psig, respectively. Carbon conversion of over 95% was achieved within 30 minutes at gasification conditions of 1800/sup 0/F and 15 psig in a hydrogen/steam gas mixture for the Indiana New Albany oil shale. This paper presents the results of the tests conducted in a laboratory-scale batch reactor to obtain reaction rate data and in a continuous mini-bench-scale unit to obtain product yield data. 2 refs., 7 figs., 4 tabs.

Isothermal kinetics of new Albany oil shale  

SciTech Connect (OSTI)

From the development of technologies for the utilization of eastern U.S. oil shales, fluidized bed pyrolysis technology is emerging as one of the most promising in terms of oil yield, operating cost, and capital investment. Bench-scale testing of eastern shales has reached a level where scale-up represents the next logical step in the evolution of this technology. A major consideration in this development and an essential part of any fluidized bed reactor scale-up effort--isothermal kinetics-- has largely been ignored for eastern US shale with the exception of a recent study conducted by Richardson et al. with a Cleveland shale. The method of Richardson et al. was used previously by Wallman et al. with western shale and has been used most recently by Forgac, also with western shale. This method, adopted for the present study, entails injecting a charge of shale into a fluidized bed and monitoring the hydrocarbon products with a flame ionization detector (FID). Advantages of this procedure are that fluidized bed heat-up effects are simulated exactly and real-time kinetics are obtained due to the on-line FID. Other isothermal methods have suffered from heat-up and cool-down effects making it impossible to observe the kinetics at realistic operating temperatures. A major drawback of the FID approach, however, is that no differentiation between oil and gas is possible.

Uniform retorting of an anisotropic shale bed  

SciTech Connect (OSTI)

In situ oil shale retorts have typically been designed for the fracturing event to produce a rubble bed having uniform cross-sectional rubble properties. This uniform rubble bed approach strived to produce constant void fraction and particle size distribution within all regions of the rubble bed. Ideally, these isotropic rubble beds have uniform flow of oxidants, retorting and combustion products. However, edge effects during the blast event typically produce channeling at the retort walls during processing, reducing the rubble sweep and the local yield. Second generation in situ retorts are addressing uniform retorting within the rubble bed rather than the uniformity of rubble bed properties. Here, the blast design produces and anisotropic rubble bed with varying particle size distribution and void fraction normal to the direction of flow. This paper describes a laboratory experiment in which a highly-instrumented, 100 kg bed of shale with zones of differing particle size and void was retorted. Shale particle size and void were varied over the retort cross-section so that a retorting front would move at a constant velocity downward through the rubble bed. The bed was designed using data from numerous pressure drop measurements on uniform shale beds of varying shale particle size distribution and void. Retorting of the bed showed a uniform retorting front and a yield comparable with that achieved in isotropic shale beds. We present thermal data and offgas, oil and shale analyses (allowing material and energy balance closures) and compare these data to previous vertical retorting experiments on uniform and non-uniform beds of shale. This experiment verifies that uniform retorting fronts can be achieved in correctly designed anisotropic beds of shale and validates the concept of uniform retorting in order increase the oil recovery in second generation retorts. 20 refs., 17 figs., 4 tabs.

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

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

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

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.

Net thickness of the radioactive shale facies in the Huron and Chagrin members of the Ohio shale  

SciTech Connect (OSTI)

The net thickness of radioactive shale is determined by first establishing a normal base line for each well based upon the gamma ray log response of shale units, such as Bedford, Chagrin, and certain units within the Olentangy, observed to be fairly consistently radioactive. Radioactive shales are then defined as those shales having a gamma ray response 20 API units or more to the right of the shale base line. The combined thickness of beds reaching the radioactive shale threshold value is reported as the net thickness of radioactive shale facies within the mapping unit.

Method for retorting oil shale  

DOE Patents [OSTI]

The recovery of oil from oil shale is provided in a fluidized bed by using a fluidizing medium of a binary mixture of carbon dioxide and 5 steam. The mixture with a steam concentration in the range of about 20 to 75 volume percent steam provides an increase in oil yield over that achievable by using a fluidizing gas of carbon dioxide or steam alone when the mixture contains higher steam concentrations. The operating parameters for the fluidized bed retorted are essentially the same as those utilized with other gaseous fluidizing mediums with the significant gain being in the oil yield recovered which is attributable solely to the use of the binary mixture of carbon dioxide and steam. 2 figs.

Oil shale mining studies and analyses of some potential unconventional uses for oil shale  

SciTech Connect (OSTI)

Engineering studies and literature review performed under this contract have resulted in improved understanding of oil shale mining costs, spent shale disposal costs, and potential unconventional uses for oil shale. Topics discussed include: costs of conventional mining of oil shale; a mining scenario in which a minimal-scale mine, consistent with a niche market industry, was incorporated into a mine design; a discussion on the benefits of mine opening on an accelerated schedule and quantified through discounted cash flow return on investment (DCFROI) modelling; an estimate of the costs of disposal of spent shale underground and on the surface; tabulation of potential increases in resource recovery in conjunction with underground spent shale disposal; the potential uses of oil shale as a sulfur absorbent in electric power generation; the possible use of spent shale as a soil stabilizer for road bases, quantified and evaluated for potential economic impact upon representative oil shale projects; and the feasibility of co-production of electricity and the effect of project-owned and utility-owned power generation facilities were evaluated. 24 refs., 5 figs., 19 tabs.

HYDRAULIC CEMENT PREPARATION FROM LURGI SPENT SHALE  

SciTech Connect (OSTI)

Low cost material is needed for grouting abandoned retorts. Experimental work has shown that a hydraulic cement can be produced from Lurgi spent shale by mixing it in a 1:1 weight ratio with limestone and heating one hour at 1000°C. With 5% added gypsum, strengths up to 25.8 MPa are obtained. This cement could make an economical addition up to about 10% to spent shale grout mixes, or be used in ordinary cement applications.

Failure surface model for oil shale  

SciTech Connect (OSTI)

One promising means of recovering oil from oil shale is to retort the shale in situ. Currently, modified in situ technology requires the construction of extensive underground openings or retorts. The remaining media (structure left around these retorts must support the overburden and contain the retorting shale. A failure criterion for oil shale, which is presented in this paper, was developed so that regions in the retort structure where the shale may be approaching failure can be identified. This criterion, adapted from composite materials applications, is essentially a closed surface in six-dimensional stress space and makes it possible to describe the anisotropic nature of failure in layered materials. The failure surface can be defined by five parameters which are determined from five simple laboratory tests. The surface is developed for a 80 ml/kg kerogen content shale and its features are discussed in detail. The predictions of the model are found to be in agreement with the results of a large number of laboratory tests, including uniaxial and triaxial compression tests. One unique (for rocks) test series is discussed which involves the failure of thin-walled tubes under combined compression and torsion. Finally, it is shown how the model can be extended to include the variation of material properties with kerogen content and temperature.

Raw shale dissolution as an aid in determining oil shale mineralogy  

SciTech Connect (OSTI)

With an accurate oil shale mineralogy, one can begin to unravel the inorganic and organic aspects of retorting and combustion chemistry. We evaluated three modern elemental analysis procedures (ICP-AES, XRF, and PIXE) with the aim of improving our knowledge of the mineral matrix. A New Albany Shale (Clegg Creek Member) specimen (NA13) and a Mahogany Zone Green River Formation oil shale from Anvil Points (AP24) were the two materials analyzed. These were oil shales that we had used in our pilot retort. We set a modest goal: determination of those materials present at greater than a 1% level with a relative accuracy of {plus_minus}10%. Various total dissolution methods and pre-treatement procedures were examined. The routine ICP-AES method that we adopted had precision and accuracy that exceeded our initial goals. Partial dissolution of carbonate minerals in acetic acid was slow but highly selective. The clay mineral content of both shales was deduced from the time dependence of dissolution in 6N HCl. An Al:K ratio of 3 indicated selective HCl solubility of the clay, illite. Our eastern oil shale from Kentucky was remarkably similar in mineral composition to high-grade-zone New Albany Shale samples from Kentucky, Indiana, and Illinois that others had subjected to careful mineral analysis. A Mahogany Zone Green River Formation oil shale from the Colony Mine had slightly different minor mineral components (relative to AP24) as shown by its gas evolution profile.

Method for maximizing shale oil recovery from an underground formation  

DOE Patents [OSTI]

A method for maximizing shale oil recovery from an underground oil shale formation which has previously been processed by in situ retorting such that there is provided in the formation a column of substantially intact oil shale intervening between adjacent spent retorts, which method includes the steps of back filling the spent retorts with an aqueous slurry of spent shale. The slurry is permitted to harden into a cement-like substance which stabilizes the spent retorts. Shale oil is then recovered from the intervening column of intact oil shale by retorting the column in situ, the stabilized spent retorts providing support for the newly developed retorts.

Retorting of oil shale followed by solvent extraction of spent shale: Experiment and kinetic analysis  

SciTech Connect (OSTI)

Samples of El-Lajjun oil shale were thermally decomposed in a laboratory retort system under a slow heating rate (0.07 K/s) up to a maximum temperature of 698--773 K. After decomposition, 0.02 kg of spent shale was extracted by chloroform in a Soxhlet extraction unit for 2 h to investigate the ultimate amount of shale oil that could be produced. The retorting results indicate an increase in the oil yields from 3.24% to 9.77% of oil shale feed with retorting temperature, while the extraction results show a decrease in oil yields from 8.10% to 3.32% of spent shale. The analysis of the data according to the global first-order model for isothermal and nonisothermal conditions shows kinetic parameters close to those reported in literature.

Coal preparation: The essential clean coal technology  

SciTech Connect (OSTI)

This chapter is a brief introduction to a broad topic which has many highly specialized areas. The aim is to summarize the essential elements of coal preparation and illustrate its important role in facilitating the clean use of coal. Conventional coal preparation is the essential first step in ensuring the economic and environmentally acceptable use of coal. The aim of coal preparation is to produce saleable products of consistent, specified quality which satisfy customer requirements while optimizing the utilization of the coal resource. Coal preparation covers all aspects of preparing coal for the market. It includes size reduction, blending and homogenization and, most importantly, the process of physical beneficiation or washing, which involves separation of undesirable mineral matter from the coal substance itself. Coal preparation can be performed at different levels of sophistication and cost. The degree of coal preparation required is decided by considering the quality of the raw coal, transport costs and, in particular, the coal quality specified by the consumer. However, the cost of coal beneficiation rises rapidly with the complexity of the process and some coal is lost with the waste matter because of process inefficiencies, therefore each situation requires individual study to determine the optimum coal preparation strategy. The necessary expertise is available within APEC countries such as Australia. Coals destined for iron making are almost always highly beneficiated. Physical beneficiation is mostly confined to the higher rank, hard coals, but all other aspects of coal preparation can be applied to subbituminous and lignitic coals to improve their utilization. Also, there are some interesting developments aimed specifically at reducing the water content of lower rank coals.

The nano-mechanical morphology of shale  

Science Journals Connector (OSTI)

Shale, the sealing formations in most hydrocarbon reservoirs, is made of highly compacted clay particles of sub-micrometer size, nanometric porosity and different mineralogy. In this paper, we propose and validate a technique to identify the nano-mechanical morphology of such a nanocomposite material. In particular, by means of a massive nanoindentation campaign at two different scales on a large range of shale materials, we show that the highly compacted plate- or sheet-like clay particles have a distinct nano-mechanical morphology with no privileged orientation of the particle-to-particle contact surface, as evidenced by a mechanical percolation threshold of ?0 ? 0.5. Furthermore, the nanoindentation results provide strong evidence that the nano-mechanical elementary building block of shales is transversely isotropic in stiffness, and isotropic and frictionless in strength. These observations lead to a sphere-like mechanical morphology for visibly plate- or sheet-like clay particles. The contact forces between the sphere-like particles activate the intrinsicly anisotropic elastic properties within the clay particles and the cohesive bonds between the clay particles. The mechanical stiffness and strength properties of porous clay scale with the clay packing density toward a unique set of shale-invariant material properties. The determination of mechanical microstructure and invariant material properties are of great importance for the development of predictive microporomechanical models of the stiffness and strength properties of shale. The approach presented here also applies to other chemically and mechanically complex materials exhibiting nanogranular behavior.

System for utilizing oil shale fines  

DOE Patents [OSTI]

A system is provided for utilizing fines of carbonaceous materials such as particles or pieces of oil shale of about one-half inch or less diameter which are rejected for use in some conventional or prior surface retorting process, which obtains maximum utilization of the energy content of the fines and which produces a waste which is relatively inert and of a size to facilitate disposal. The system includes a cyclone retort (20) which pyrolyzes the fines in the presence of heated gaseous combustion products, the cyclone retort having a first outlet (30) through which vapors can exit that can be cooled to provide oil, and having a second outlet (32) through which spent shale fines are removed. A burner (36) connected to the spent shale outlet of the cyclone retort, burns the spent shale with air, to provide hot combustion products (24) that are carried back to the cyclone retort to supply gaseous combustion products utilized therein. The burner heats the spent shale to a temperature which forms a molten slag, and the molten slag is removed from the burner into a quencher (48) that suddenly cools the molten slag to form granules that are relatively inert and of a size that is convenient to handle for disposal in the ground or in industrial processes.

Print Thursday, 03 January 2013 00:00 Over 20 trillion cubic meters of natural gas are trapped in shale, but many shale oil and gas producers still use models of underground fluid flow that date back to the heyday of easy-to-tap gas and liquid crude. The source of shale oil and gas is kerogen, an organic material in the shale, but until now kerogen hasn't been incorporated in mathematical models of shale gas reservoirs. Paulo Monteiro, Chris Rycroft, and Grigory Isaakovich Barenblatt, with the Computational Research Division and the Advanced Light Source, recently modeled how pressure gradients in the boundary layer between kerogen inclusions and shale matrices affect productivity and can model reservoir longevity.

NATURAL GAS FROM SHALE: Questions and Answers  

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

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

DOE Patents [OSTI]

The present invention is directed to the extraction of energy values from l shale containing considerable concentrations of calcium carbonate in an efficient manner. The volatiles are separated from the oil shale in a retorting zone of a fluidized bed where the temperature and the concentration of oxygen are maintained at sufficiently low levels so that the volatiles are extracted from the oil shale with minimal combustion of the volatiles and with minimal calcination of the calcium carbonate. These gaseous volatiles and the calcium carbonate flow from the retorting zone into a freeboard combustion zone where the volatiles are burned in the presence of excess air. In this zone the calcination of the calcium carbonate occurs but at the expense of less BTU's than would be required by the calcination reaction in the event both the retorting and combustion steps took place simultaneously. The heat values in the products of combustion are satisfactorily recovered in a suitable heat exchange system.

Clean coal  

SciTech Connect (OSTI)

The article describes the physics-based techniques that are helping in clean coal conversion processes. The major challenge is to find a cost- effective way to remove carbon dioxide from the flue gas of power plants. One industrially proven method is to dissolve CO{sub 2} in the solvent monoethanolamine (MEA) at a temperature of 38{sup o}C and then release it from the solvent in another unit when heated to 150{sup o}C. This produces CO{sub 2} ready for sequestration. Research is in progress with alternative solvents that require less energy. Another technique is to use enriched oxygen in place of air in the combustion process which produces CO{sub 2} ready for sequestration. A process that is more attractive from an energy management viewpoint is to gasify coal so that it is partially oxidized, producing a fuel while consuming significantly less oxygen. Several IGCC schemes are in operation which produce syngas for use as a feedstock, in addition to electricity and hydrogen. These schemes are costly as they require an air separation unit. Novel approaches to coal gasification based on 'membrane separation' or chemical looping could reduce the costs significantly while effectively capturing carbon dioxide. 1 ref., 2 figs., 1 photo.

Coal-liquid fuel/diesel engine operating compatibility. Final report  

SciTech Connect (OSTI)

This work is intended to assess the possibilities of using coal-derived liquids (CDL) represented by a specific type (SRC II) and shale-derived distillate fuel in blends of petroleum-derived fuels in medium-speed, high-output, heavy-duty diesel engines. Conclusions are as follows: (1) Blends of solvent refined coal and diesel fuel may be handled safely by experienced diesel engine mechanics. (2) A serious corrosion problem was found in the fuel pump parts when operating with solvent refined coal blended with petroleum. It is expected that a metallurgy change can overcome this problem. (3) Proper selection of materials for the fuel system is required to permit handling coal-derived liquid fuels. (4) A medium speed, high horsepower, 4-cycle diesel engine can be operated on blends of solvent refined coal and petroleum without serious consequences save the fuel system corrosion previously mentioned. This is based on a single, short durability test. (5) As represented by the product evaluated, 100% shale-derived distillate fuel may be used in a medium speed, high horsepower, 4-cycle diesel engine without significant consequences. (6) The shale product evaluated may be blended with petroleum distillate or petroleum residual materials and used as a fuel for medium speed, high horsepower, 4-cycle diesel engines. 7 references, 24 figures, 20 tables.

A fresh look at coal-derived liquid fuels  

SciTech Connect (OSTI)

35% of the world's energy comes from oil, and 96% of that oil is used for transportation. The current number of vehicles globally is estimated to be 700 million; that number is expected to double overall by 2030, and to triple in developing countries. Now consider that the US has 27% of the world's supply of coal yet only 2% of the oil. Coal-to-liquids technologies could bridge the gap between US fuel supply and demand. The advantages of coal-derived liquid fuels are discussed in this article compared to the challenges of alternative feedstocks of oil sands, oil shale and renewable sources. It is argued that pollutant emissions from coal-to-liquid facilities could be minimal because sulfur compounds will be removed, contaminants need to be removed for the FT process, and technologies are available for removing solid wastes and nitrogen oxides. If CO{sub 2} emissions for coal-derived liquid plants are captured and sequestered, overall emissions of CO{sub 2} would be equal or less than those from petroleum. Although coal liquefaction requires large volumes of water, most water used can be recycled. Converting coal to liquid fuels could, at least in the near term, bring a higher level of stability to world oil prices and the global economy and could serve as insurance for the US against price hikes from oil-producing countries. 7 figs.

NATURAL GAS FROM SHALE: Questions and Answers It Seems Like Shale Gas Came Out  

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

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

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

Science Journals Connector (OSTI)

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

Producing liquid fuels from coal: prospects and policy issues  

SciTech Connect (OSTI)

The increase in world oil prices since 2003 has prompted renewed interest in producing and using liquid fuels from unconventional resources, such as biomass, oil shale, and coal. This book focuses on issues and options associated with establishing a commercial coal-to-liquids (CTL) industry within the United States. It describes the technical status, costs, and performance of methods that are available for producing liquids from coal; the key energy and environmental policy issues associated with CTL development; the impediments to early commercial experience; and the efficacy of alternative federal incentives in promoting early commercial experience. Because coal is not the only near-term option for meeting liquid-fuel needs, this book also briefly reviews the benefits and limitations of other approaches, including the development of oil shale resources, the further development of biomass resources, and increasing dependence on imported petroleum. A companion document provides a detailed description of incentive packages that the federal government could offer to encourage private-sector investors to pursue early CTL production experience while reducing the probability of bad outcomes and limiting the costs that might be required to motivate those investors.

ANALYSIS OF DEVONIAN BLACK SHALE IN ANALYSIS OF DEVONIAN BLACK SHALE IN KENTUCKY FOR POTENTIAL CARBON DIOXIDE SEQUESTRATION AND ENHANCED NATURAL GAS PRODUCTION Background Global climate change is an area of increasing concern, and many scientists believe the cause is due, at least in part, to increased emissions of CO 2 , especially from the combustion of fossil fuels. These concerns are driving initiatives to develop carbon management technologies. One promising approach is geologic sequestration of CO 2 . Options being investigated include sequestration in saline aquifers, oil and gas reservoirs, and unminable coal seams In analogy with sequestration in coal seams, another option may be sequestration in Devonian black shales, organic-rich rocks that serve as both a source and trap for natural gas.

A study of ignition of oil shale and char  

SciTech Connect (OSTI)

The ignition characteristics of Fushun, Maoming and Jordan oil shale samples have been determined experimentally by using thermogravimetric analyzer (TGA) and CO/CO{sub 2} analyzer. Their chars have been investigated, too. Two ignition mechanisms for oil shale and shale char are suggested. One is called heterogeneous, according to which, the ignition takes place on the surface of the oil shale and/or shale char sample. Another is called homogeneous, the ignition occurring in the gas phase surrounding the particles. The ignition mechanism occurred mainly depends on the condition of the combustion, physical properties of samples and the rate of volatile release. The experimental equations of ignition for three kinds of oil shale and their char particles (Fushun, Maoming and Jordan) are given. The difference of ignition temperatures for these oil shale and their char particles are compared in terms of chemical compositions and physical properties.

Eight samples reported in the literature were included in this analysis. Variations in the first three constituents account for over 99% of the variation in the heats of combustion. For the burnt shales, account must also be taken of the partial conversion of iron sulfides to sulfates.

Soil stabilization using oil-shale solid waste  

SciTech Connect (OSTI)

Oil-shale solid wastes are evaluated for use as soil stabilizers. A laboratory study consisted of the following tests on compacted samples of soil treated with water and spent oil shale: unconfined compressive strength, moisture-density relationships, wet-dry and freeze-thaw durability, and resilient modulus. Significant increases in strength, durability, and resilient modulus were obtained by treating a silty sand with combusted western oil shale. Moderate increases in durability and resilient modulus were obtained by treating a highly plastic clay with combusted western oil shale. Solid waste from eastern oil shale appears to be feasible for soil stabilization only if limestone is added during combustion. Testing methods, results, and recommendations for mix design of spent shale-stabilized pavement subgrades are presented and the mechanisms of spent-shale cementation are discussed.

Clean Coal Technology Program Clean Coal Technology Program Clean Coal 101 Lesson 2: The Clean Coal Technology Program The Clean Coal Technology Program began in 1985 when the United States and Canada decided that something had to be done about the "acid rain" that was believed to be damaging rivers, lakes, forests, and buildings in both countries. Since many of the pollutants that formed "acid rain" were coming from big coal-burning power plants in the United States, the U.S. Government took the lead in finding a solution. One of the steps taken by the U.S. Department of Energy was to create a partnership program between the Government, several States, and private companies to test new methods developed by scientists to make coal burning much cleaner. This became the "Clean Coal Technology Program."

Brine inclusions in halite and the origin of the Middle Devonian Prairie evaporites of Western Canada  

SciTech Connect (OSTI)

Brines were extracted from fluid inclusions in Lower Salt halite of the Middle Devonian Prairie Formation in Saskatchewan, Canada. The brines were analyzed by ion chromatography and were found to be of the Na-K-Mg-Ca-Cl type. They do not fall along a simple evaporation trend. Brines from clear, diagenetic halite are significantly lower in Na{sup +} and higher in Mg{sup 2+}, and Cl{sup {minus}} than brines from cloudy, subaqueously formed halite with chevron structures. The isotopic composition of strontium and sulfur in anhydrite associated with the halites was found to be the same as that of Middle Devonian seawater. The composition of the inclusion brines can be derived from that of modern seawater by evaporation, extensive dolomitization of limestone, and albitization of clay minerals. Other evolution paths are, however, also feasible, and it is impossible to rule out effects due to the addition of nonmarine waters (hydrothermal solutions, surface runoff, and groundwater), or dissolutional recycling of existing evaporites within the Prairie evaporite basin. These analyses and published data on brine inclusions in halite from a number of Phanerozoid evaporite deposits show that the Na-K-Mg-Ca-Cl type brine is more common than the Na-K-Mg-Cl-SO{sub 4} type, which is expected from evaporation of modern seawater.

RESOURCE ASSESSMENT & PRODUCTION TESTING FOR COAL BED METHANE IN THE ILLINOIS BASIN  

SciTech Connect (OSTI)

The geological surveys of Illinois, Indiana and Kentucky have completed the initial geologic assessment of their respective parts of the Illinois Basin. Cumulative thickness maps have been generated and target areas for drilling have been selected. The first well in the Illinois area of the Illinois Basin coal bed methane project was drilled in White County, Illinois in October 2003. This well was cored in the major coal interval from the Danville to the Davis Coals and provided a broad spectrum of samples for further analyses. Sixteen coal samples and three black shale samples were taken from these cores for canister desorption tests and were the subject of analyses that were completed over the following months, including desorbed gas volume, gas chemical and isotope composition, coal proximate, calorific content and sulfur analyses. Drilling programs in Indiana and Kentucky are expected to begin shortly.

Oil shale ash-layer thickness and char combustion kinetics  

SciTech Connect (OSTI)

A Hot-Recycled-Solids (HRS) oil shale retort is being studied at Lawrence Livermore National Laboratory. In the HRS process, raw shale is heated by mixing it with burnt retorted shale. Retorted shale is oil shale which has been heated in an oxygen deficient atmosphere to pyrolyze organic carbon, as kerogen into oil, gas, and a nonvolatile carbon rich residue, char. In the HRS retort process, the char in the spent shale is subsequently exposed to an oxygen environment. Some of the char, starting on the outer surface of the shale particle, is burned, liberating heat. In the HRS retort, the endothermic pyrolysis step is supported by heat from the exothermic char combustion step. The rate of char combustion is controlled by three resistances; the resistance of oxygen mass transfer through the gas film surrounding the solid particle, resistance to mass transfer through a ash layer which forms on the outside of the solid particles as the char is oxidized and the resistance due to the intrinsic chemical reaction rate of char and oxygen. In order to estimate the rate of combustion of the char in a typical oil shale particle, each of these resistances must be accurately estimated. We begin by modeling the influence of ash layer thickness on the over all combustion rate of oil shale char. We then present our experimental measurements of the ash layer thickness of oil shale which has been processed in the HRS retort.

Water management practices used by Fayetteville shale gas producers.  

SciTech Connect (OSTI)

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

Los Alamos environmental activities/oil shale effluents  

SciTech Connect (OSTI)

The objectives of this research are to determine the nature, magnitude, and time dependence of the major and trace element releases as functions of the raw shale mineralogy, retorting conditions, and spent shale mineral assemblages. These experimental studies will focus on retorting variable regimes characteristic of most retorting processes. As an adjunct objective, the relation of laboratory results to those obtained from both bench-scale and pilot-scale retorts, when both have been operated under similar retorting conditions, will be defined. The goal is to develop a predictive capability for spent shale chemistry as a function of the raw material feedstock and process parameters. Key accomplishments follow: completed an overview of health, environmental effects, and potential ''show stoppers'' in oil shale development; elucidated the importance of both raw material and process in the identity and behavior of spent shale wastes (Occidental raw and spent shales from the Logan Wash site); completed a balanced factorial design experiment to investigate the influence of shale type, temperature, and atmosphere on spent shale behavior; compared the behavior of spent shales from laboratory experiments with shales generated from MIS retorting by OOSI at Logan Wash, Colorado; completed a study of the partitioning of minerals, inorganics, and organics as a function of particle size in a raw shale from Anvil Points, Colorado; evaluated the application of the Los Alamos nuclear microprobe to the characterization of trace element residences in shale materials; established the use of chemometrics as a major tool for evaluating large data bases in oil shale research and for relating field and laboratory results; conceptualized and evaluated experimentally a multistaged leaching control for abandonment of underground retorts; and coordinated activities with other DOE laboratories, industry laboratories, and universities. 13 refs., 1 fig., 2 tabs.

A feasibility study of oil shale fired pulse combustors with applications to oil shale retorting  

SciTech Connect (OSTI)

The results of the experimental investigation performed to determine the feasibility of using pulverized Colorado oil shale to fuel a bench scale pulse combustor reveal that oil shale cannot sustain pulsations when used alone as fuel. Trace amounts of propane mixed with the oil shale enabled the pulsations, however. Up to 80% of the organic material in the oil shale was consumed when it was mixed with propane in the combustor. Beyond the feasibility objectives, the operating conditions of the combustor fuel with propane and mixtures of oil shale and propane were characterized with respect to pulsation amplitude and frequency and the internal combustor wall temperature over fuel lean and fuel rich stoichiometries. Maximum pressure excursions of 12.5 kPa were experienced in the combustor. Pulsation frequencies ranged from 50 to nearly 80 Hz. Cycle resolved laser Doppler anemometry velocities were measured at the tail pipe exit plane. Injecting inert mineral matter (limestone) into the pulse combustor while using propane fuel had only a slight effect on the pulsation frequency for the feed rates tested.

Utilization of Estonian oil shale at power plants  

SciTech Connect (OSTI)

Estonian oil shale belongs to the carbonate class and is characterized as a solid fuel with very high mineral matter content (60--70% in dry mass), moderate moisture content (9--12%) and low heating value (LHV 8--10 MJ/kg). Estonian oil shale deposits lie in layers interlacing mineral stratas. The main constituent in mineral stratas is limestone. Organic matter is joined with sandy-clay minerals in shale layers. Estonian oil shale at power plants with total capacity of 3060 MW{sub e} is utilized in pulverized form. Oil shale utilization as fuel, with high calcium oxide and alkali metal content, at power plants is connected with intensive fouling, high temperature corrosion and wear of steam boiler`s heat transfer surfaces. Utilization of Estonian oil shale is also associated with ash residue use in national economy and as absorbent for flue gas desulfurization system.

Western oil shale conversion using the ROPE copyright process  

SciTech Connect (OSTI)

Western Research Institute (WRI) is continuing to develop the Recycle Oil Pyrolysis and Extraction (ROPE) process to recover liquid hydrocarbon products from oil shale, tar sand, and other solid hydrocarbonaceous materials. The process consists of three major steps: (1) pyrolyzing the hydrocarbonaceous material at a low temperature (T {le} 400{degrees}C) with recycled product oil, (2) completing the pyrolysis of the residue at a higher temperature (T > 400{degrees}C) in the absence of product oil, and (3) combusting the solid residue and pyrolysis gas in an inclined fluidized-bed reactor to produce process heat. Many conventional processes, such as the Paraho and Union processes, do not use oil shale fines (particles smaller than 1.27 cm in diameter). The amount of shale discarded as fines from these processes can be as high as 20% of the total oil shale mined. Research conducted to date suggests that the ROPE process can significantly improve the overall oil recovery from western oil shale by processing the oil shale fines typically discarded by conventional processes. Also, if the oil shale fines are co-processed with shale oil used as the heavy recycle oil, a better quality oil will be produced that can be blended with the original shale oil to make an overall produce that is more acceptable to the refineries and easier to pipeline. Results from tests conducted in a 2-inch process development unit (PDU) and a 6-inch bench-scale unit (BSU) with western oil shale demonstrated a maximum oil yield at temperatures between 700 and 750{degrees}F (371 and 399{degrees}C). Test results also suggest that the ROPE process has a strong potential for recovering oil from oil shale fines, upgrading shale oil, and separating high-nitrogen-content oil for use as an asphalt additive. 6 refs., 10 figs., 11 tabs.

Investigations into coal coprocessing and coal liquefaction  

SciTech Connect (OSTI)

The conversion of coal to liquid suitable as feedstock to a petroleum refinery is dependent upon several process variables. These variables include temperature, pressure, coal rank, catalyst type, nature of the feed to the reactor, type of process, etc. Western Research Institute (WRI) has initiated a research program in the area of coal liquefaction to address the impact of some of these variables upon the yield and quality of the coal-derived liquid. The principal goal of this research is to improve the efficiency of the coal liquefaction process. Two different approaches are currently being investigated. These include the coprocessing of a heavy liquid, such as crude oil, and coal using a dispersed catalyst and the direct liquefaction of coal using a supported catalyst. Another important consideration in coal liquefaction is the utilization of hydrogen, including both externally- and internally-supplied hydrogen. Because the incorporation of externally-supplied hydrogen during conversion of this very aromatic fossil fuel to, for example, transportation fuels is very expensive, improved utilization of internally-supplied hydrogen can lead to reducing processing costs. The objectives of this investigation, which is Task 3.3.4, Coal Coprocessing, of the 1991--1992 Annual Research Plan, are: (1) to evaluate coal/oil pretreatment conditions that are expected to improve the liquid yield through more efficient dispersion of an oil-soluble, iron-based catalyst, (2) to characterize the coke deposits on novel, supported catalysts after coal liquefaction experiments and to correlate the carbon skeletal structure parameters of the coke deposit with catalyst performance as measured by coal liquefaction product yield, and (3) to determine the modes of hydrogen utilization during coal liquefaction and coprocessing. Experimental results are discussed in this report.

Induction log analysis of thinly laminated sand/shale formation  

SciTech Connect (OSTI)

The author examines induction log responses to a thinly laminated sand/shale sequence in a deviated borehole for arbitrary deviation (or dip) angle and sand/shale composition. He found that the induction log responses in a thinly laminated sand/shale sequence are the same as they would be if the tool is placed in a homogeneous but anisotropic formation with the horizontal and vertical conductivities given respectively by the parallel and the series conductivities of the sequence. Conversely, a thinly laminated sand/shale sequence can be identified as an anisotropic formation by induction logs. He discusses three methods to identify an anisotropic formation using induction-type logs alone.

Attrition and abrasion models for oil shale process modeling  

SciTech Connect (OSTI)

As oil shale is processed, fine particles, much smaller than the original shale are created. This process is called attrition or more accurately abrasion. In this paper, models of abrasion are presented for oil shale being processed in several unit operations. Two of these unit operations, a fluidized bed and a lift pipe are used in the Lawrence Livermore National Laboratory Hot-Recycle-Solid (HRS) process being developed for the above ground processing of oil shale. In two reports, studies were conducted on the attrition of oil shale in unit operations which are used in the HRS process. Carley reported results for attrition in a lift pipe for oil shale which had been pre-processed either by retorting or by retorting then burning. The second paper, by Taylor and Beavers, reported results for a fluidized bed processing of oil shale. Taylor and Beavers studied raw, retorted, and shale which had been retorted and then burned. In this paper, empirical models are derived, from the experimental studies conducted on oil shale for the process occurring in the HRS process. The derived models are presented along with comparisons with experimental results.

INVESTIGATIONS ON HYDRAULIC CEMENTS FROM SPENT OIL SHALE  

SciTech Connect (OSTI)

A process for making hydraulic cements from spent oil shale is described in this paper. Inexpensive cement is needed to grout abandoned in-situ retorts of spent shale for subsidence control, mitigation of leaching, and strengthening the retorted mass in order to recover oil from adjacent pillars of raw shale. A hydraulic cement was produced by heating a 1:1 mixture of Lurgi spent shale and CaCO{sub 3} at 1000 C for one hour. This cement would be less expensive than ordinary portland cement and is expected to fulfill the above requirements.

Secondary recovery from a stromatoporoid buildup: Devonian Duperow Formation, Ridgelawn field, Montana  

SciTech Connect (OSTI)

Ridgelawn field is located in Richland County, Montana, in the western part of the Williston basin. It is a multiple-pay field, with production from ordovician, Devonian, and Mississippian carbonates. Discovered in 1980, the field was recently unitized in the Devonian Duperow Formation for purposes of secondary recovery by waterflood. In this part of the Williston, the Duperow consists of a repetitive succession of shoaling-upward carbonate cycles, each deposited under increasingly restricted conditions on a shallow marine shelf. Production at Ridgelaw occurs from dolomites within one of these cycles, cycle IIIa. Three separate, laterally continuous porosity zones (here termed a, b, and c, from lowest to highest) are recognized and mapped individually in the field. The reservoir has a lensoidal geometry; porous dolomite thins and grades laterally into tight carbonate. The Duperow pool at Ridgelawn is a solution gas drive reservoir. Computer log analysis of the Duperow pay interval indicates an average true porosity of 11.8% and an average initial water saturation of 17.7%. Net pay, defined as greater than 5% crossplot porosity, averages 16.6 ft across the field. Petrographic analysis and log calibration suggests that different facies in each of the three porosity zones were preferentially dolomitized to create reservoir-quality rock; each is now a sucrosic dolomite with intercrystalline porosity. Porosity can be occluded (most often in the upper two zones b and c) by both calcite and anhydrite cements. The lowermost zone, a, is related to a stromatoporoid/coralline bank, and has excellent but highly variable porosity and permeability. The two upper zones, b and c, are more finely crystalline dolomite and represent shallower water depositional facies. Maps for each zone, including porosity, porosity-feet, net pay, and water saturation were constructed and used for equity determination in the unit.

Upgraded Coal Interest Group  

SciTech Connect (OSTI)

The Upgraded Coal Interest Group (UCIG) is an EPRI 'users group' that focuses on clean, low-cost options for coal-based power generation. The UCIG covers topics that involve (1) pre-combustion processes, (2) co-firing systems and fuels, and (3) reburn using coal-derived or biomass-derived fuels. The UCIG mission is to preserve and expand the economic use of coal for energy. By reducing the fuel costs and environmental impacts of coal-fired power generation, existing units become more cost effective and thus new units utilizing advanced combustion technologies are more likely to be coal-fired.

Conceptual study of thermal stimulation in shale gas formations  

Science Journals Connector (OSTI)

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

The purpose of this research program is to understand the potential impact of an oil shale industry on environmental levels of trace contaminants in the region. The program involves a comprehensive study of the sources, release mechanisms, transport, fate, and effects of toxic trace chemicals, principally the trace elements, in an oil shale industry. The overall objective of the program is to evaluate the environmental and health consequences of the release of toxic trace elements by shale and oil production and use. The baseline geochemical survey shows that stable trace elements maps can be constructed for numerous elements and that the trends observed are related to geologic and climatic factors. Shale retorted by above-ground processes tends to be very homogeneous (both in space and in time) in trace element content. Leachate studies show that significant amounts of B, F, and Mo are released from retorted shales and while B and Mo are rapidly flushed out, F is not. On the other hand, As, Se, and most other trace elements are not present in significant quantities. Significant amounts of F and B are also found in leachates of raw shales. Very large concentrations of reduced sulfur species are found in leachates of processed shale. Very high levels of B and Mo are taken up in some plants growing on processed shale with and without soil cover. There is a tendency for some trace elements to associate with specific organic fractions, indicating that organic chelation or complexation may play an important role. Many of the so-called standard methods for analyzing trace elements in oil shale-related materials are inadequate. A sampling manual is being written for the environmental scientist and practicing engineer. A new combination of methods is developed for separating the minerals in oil shale into different density fractions. Microbial investigations have tentatively identified the existence of thiobacilli in oil shale materials such as leachates. (DC)

Coal Combustion Science  

SciTech Connect (OSTI)

The objective of this activity is to support the Office of Fossil Energy in executing research on coal combustion science. This activity consists of basic research on coal combustion that supports both the Pittsburgh Energy Technology Center Direct Utilization Advanced Research and Technology Development Program, and the International Energy Agency Coal Combustion Science Project. Specific tasks for this activity include: (1) coal devolatilization - the objective of this risk is to characterize the physical and chemical processes that constitute the early devolatilization phase of coal combustion as a function of coal type, heating rate, particle size and temperature, and gas phase temperature and oxidizer concentration; (2) coal char combustion -the objective of this task is to characterize the physical and chemical processes involved during coal char combustion as a function of coal type, particle size and temperature, and gas phase temperature and oxygen concentration; (3) fate of mineral matter during coal combustion - the objective of this task is to establish a quantitative understanding of the mechanisms and rates of transformation, fragmentation, and deposition of mineral matter in coal combustion environments as a function of coal type, particle size and temperature, the initial forms and distribution of mineral species in the unreacted coal, and the local gas temperature and composition.

Method oil shale pollutant sorption/NO.sub.x reburning multi-pollutant control  

DOE Patents [OSTI]

A method of decreasing pollutants produced in a combustion process. The method comprises combusting coal in a combustion chamber to produce at least one pollutant selected from the group consisting of a nitrogen-containing pollutant, sulfuric acid, sulfur trioxide, carbonyl sulfide, carbon disulfide, chlorine, hydroiodic acid, iodine, hydrofluoric acid, fluorine, hydrobromic acid, bromine, phosphoric acid, phosphorous pentaoxide, elemental mercury, and mercuric chloride. Oil shale particles are introduced into the combustion chamber and are combusted to produce sorbent particulates and a reductant. The at least one pollutant is contacted with at least one of the sorbent particulates and the reductant to decrease an amount of the at least one pollutant in the combustion chamber. The reductant may chemically reduce the at least one pollutant to a benign species. The sorbent particulates may adsorb or absorb the at least one pollutant. A combustion chamber that produces decreased pollutants in a combustion process is also disclosed.

A time-temperature-concentration matrix for induced sediment formation in shale diesel fuel  

SciTech Connect (OSTI)

Deterioration in fuel quality with time has been a continuing problem in the utilization of middle distillate fuels. These stability problems will intensify as we develop alternative sources of fuel, such as shale oil and coal. Present knowledge has suggested that for some fuels, nitrogen heterocycles may play a causative role in the formation of insoluble sediments and gums under conditions of ambient and accelerated storage. In light of the high costs of fuel processing, substantial savings could be realized if
