Fracturing controlled primary migration of hydrocarbon fluids during heating of organic-rich shales  

E-Print Network (OSTI)

Time-resolved three-dimensional in situ high resolution synchrotron x-ray tomographic imaging was used to investigate the effects of slowly heating organic-rich Green River Shale from 60\\deg; to 400\\deg;C, in air without confinement, to better understand primary migration of hydrocarbon fluids in very low permeability source rock. Cracks nucleate in the interior of the sample at a temperature around 350\\deg;C. As the temperature increases, they grow and coalesce along lamination planes to form bigger cracks. This process is accompanied by a release of light hydrocarbons generated by decomposition of the initially immature organic matter, as determined by thermogravimetry and gas chromatography. These results provide the first 4D monitoring of an invasion percolation-like fracturing process in organic-rich shales. This process increases the permeability of the sample and provides pathways for fluid expulsion - an effect that might also be relevant for primary migration under natural conditions. We propose a 2D...

4D imaging of fracturing in organic-rich shales during heating  

Science Conference Proceedings (OSTI)

To better understand the mechanisms of fracture pattern development and fluid escape in low permeability rocks, we performed time-resolved in situ X-ray tomography imaging to investigate the processes that occur during the slow heating (from 60 to 400 C) of organic-rich Green River shale. At about 350 C cracks nucleated in the sample, and as the temperature continued to increase, these cracks propagated parallel to shale bedding and coalesced, thus cutting across the sample. Thermogravimetry and gas chromatography revealed that the fracturing occurring at {approx}350 C was associated with significant mass loss and release of light hydrocarbons generated by the decomposition of immature organic matter. Kerogen decomposition is thought to cause an internal pressure build up sufficient to form cracks in the shale, thus providing pathways for the outgoing hydrocarbons. We show that a 2D numerical model based on this idea qualitatively reproduces the experimentally observed dynamics of crack nucleation, growth and coalescence, as well as the irregular outlines of the cracks. Our results provide a new description of fracture pattern formation in low permeability shales.

A 4D Synchrotron X-Ray-Tomography Study of the Formation of Hydrocarbon- Migration Pathways in Heated Organic-Rich Shale  

Science Conference Proceedings (OSTI)

Recovery of oil from oil shales and the natural primary migration of hydrocarbons are closely related processes that have received renewed interest in recent years because of the ever tightening supply of conventional hydrocarbons and the growing production of hydrocarbons from low-permeability tight rocks. Quantitative models for conversion of kerogen into oil and gas and the timing of hydrocarbon generation have been well documented. However, lack of consensus about the kinetics of hydrocarbon formation in source rocks, expulsion timing, and how the resulting hydrocarbons escape from or are retained in the source rocks motivates further investigation. In particular, many mechanisms have been proposed for the transport of hydrocarbons from the rocks in which they are generated into adjacent rocks with higher permeabilities and smaller capillary entry pressures, and a better understanding of this complex process (primary migration) is needed. To characterize these processes, it is imperative to use the latest technological advances. In this study, it is shown how insights into hydrocarbon migration in source rocks can be obtained by using sequential high-resolution synchrotron X-ray tomography. Three-dimensional images of several immature "shale" samples were constructed at resolutions close to 5 um. This is sufficient to resolve the source-rock structure down to the grain level, but very-fine-grained silt particles, clay particles, and colloids cannot be resolved. Samples used in this investigation came from the R-8 unit in the upper part of the Green River shale, which is organic rich, varved, lacustrine marl formed in Eocene Lake Uinta, USA. One Green River shale sample was heated in situ up to 400 degrees C as X-ray-tomography images were recorded. The other samples were scanned before and after heating at 400 degrees C. During the heating phase, the organic matter was decomposed, and gas was released. Gas expulsion from the low-permeability shales was coupled with formation of microcracks. The main technical difficulty was numerical extraction of microcracks that have apertures in the 5- to 30-um range (with 5 um being the resolution limit) from a large 3D volume of X-ray attenuation data. The main goal of the work presented here is to develop a methodology to process these 3D data and image the cracks. This methodology is based on several levels of spatial filtering and automatic recognition of connected domains. Supportive petrographic and thermogravimetric data were an important complement to this study. An investigation of the strain field using 2D image correlation analyses was also performed. As one application of the 4D (space + time) microtomography and the developed workflow, we show that fluid generation was accompanied by crack formation. Under different conditions, in the subsurface, this might provide paths for primary migration.

Intergrated study of the Devonian-age black shales in eastern Ohio. Final report  

Science Conference Proceedings (OSTI)

This integrated study of the Devonian-age shales in eastern Ohio by the Ohio Department of Natural Resources, Division of Geological Survey is part of the Eastern Gas Shales Project sponsored by the US Department of Energy. The six areas of research included in the study are: (1) detailed stratigraphic mapping, (2) detailed structure mapping, (3) mineralogic and petrographic characterization, (4) geochemical characterization, (5) fracture trace and lineament analysis, and (6) a gas-show monitoring program. The data generated by the study provide a basis for assessing the most promising stratigraphic horizons for occurrences of natural gas within the Devonian shale sequence and the most favorable geographic areas of the state for natural gas exploration and should be useful in the planning and design of production-stimulation techniques. Four major radioactive units in the Devonian shale sequence are believed to be important source rocks and reservoir beds for natural gas. In order of potential for development as an unconventional gas resource, they are (1) lower and upper radioactive facies of the Huron Shale Member of the Ohio Shale, (2) upper Olentangy Shale (Rhinestreet facies equivalent), (3) Cleveland Shale Member of the Ohio Shale, and (4) lower Olentangy Shale (Marcellus facies equivalent). These primary exploration targets are recommended on the basis of areal distribution, net thickness of radioactive shale, shows of natural gas, and drilling depth to the radioactive unit. Fracture trends indicate prospective areas for Devonian shale reservoirs. Good geological prospects in the Devonian shales should be located where the fracture trends coincide with thick sequences of organic-rich highly radioactive shale.

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

SciTech Connect

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

SHALE OIL--THE ELUSIVE ENERGY  

E-Print Network (OSTI)

An early settler in the valley of Parachute Creek in western Colorado built a log cabin, and made the fireplace and chimney out of the easily cut, locally abundant black rock. The pioneer invited a few neighbors to a house warming. As the celebration began, he lit a fire. The fireplace, chimney, and ultimately the whole cabin caught fire, and burned to the ground. The rock was oil shale. It was a sensational house warming! Oil shales are reported to have been set afire by lightning strikes. The Ute Indians of northwestern Colorado told stories of "mountains that burned. " Cowboys and ranchers of the region burned the dark rock in their fires, like coal. The flammable nature of the richer oil shales is basis for the title of a fascinating book by H. K. Savage (1967), The Rock That Burns. During oil shale enthusiasms in the early part of this century, stock promoters brought pieces of oil shale to Chicago street corners and set them afire. Clouds of smoke attracted crowds, and the promoters sold stock in oil shale companies. Nature of oil shale. Shale oil comes from oil shale, but oil shale is a misnomer. It is neither a true shale nor does it generally have any oil in it. It is better identified as organic marlstone, marl being a mixture of clay and calcium carbonate. The organic material is kerogen, derived from myriad organisms, chiefly plants. Savage (1967) notes the term "oil shale " is a promotional term: "The magic word 'oil ' would raise large sums of promotion money while organic marlstone wouldn't raise a dime." The U. S. Geological Survey (USGS) defines oil shale as "organic-rich shale that yields substantial quantities of oil by conventional methods of destructive distillation of the contained organic matter, which employ low confining pressures in a closed retort system.

Analysis of Devonian Black Shales in Kentucky for Potential Carbon Dioxide Sequestration and Enhanced Natural Gas Production  

Science Conference Proceedings (OSTI)

Carbonaceous (black) Devonian gas shales underlie approximately two-thirds of Kentucky. In these shales, natural gas occurs in the intergranular and fracture porosity and is adsorbed on clay and kerogen surfaces. This is analogous to methane storage in coal beds, where CO2 is preferentially adsorbed, displacing methane. Black shales may similarly desorb methane in the presence of CO2. Drill cuttings from the Kentucky Geological Survey Well Sample and Core Library were sampled to determine both CO2 and CH4 adsorption isotherms. Sidewall core samples were acquired to investigate CO2 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. CO2 adsorption capacities at 400 psi range from a low of 14 scf/ton in less organic-rich zones to more than 136 scf/ton in the more organic-rich zones. There is a direct linear correlation between measured total organic carbon content and the adsorptive capacity of the shale; CO2 adsorption capacity increases with increasing organic carbon content. Initial volumetric estimates based on these data indicate a CO2 sequestration capacity of as much as 28 billion tons total in the deeper and thicker parts of the Devonian shales in Kentucky. In the Big Sandy Gas Field area of eastern Kentucky, calculations using the net thickness of shale with 4 percent or greater total organic carbon, indicate that 6.8 billion tonnes of CO2 could be sequestered in the five county area. Discounting the uncertainties in reservoir volume and injection efficiency, these results indicate that the black shales of Kentucky are a potentially large geologic sink for CO2. Moreover, the extensive occurrence of gas shales in Paleozoic and Mesozoic basins across North America make them an attractive regional target for economic CO2 storage and enhanced natural gas production.

The Antrim Shale: Structural and stratigraphic influences on gas production  

Science Conference Proceedings (OSTI)

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

Millimeter wave analysis of the dielectric properties of oil shales  

E-Print Network (OSTI)

Natural sedimentation processes give rise to fine layers in shales. If these layers alternate between organic-rich and organic-poor sediments, then the contrast in dielectric properties gives rise to an effective birefringence as the presence of hydrocarbons suppresses the dielectric constant of the host rock. We have measured these effects with a quasioptical millimeter wave setup that is rapid and noncontacting. We find that the strength of this birefringence and the overall dielectric permittivity provide two useful diagnostic of the organic content of oil shales.

Pyrolysis and hydrocarbon source bed potential of the Upper Devonian Woodford Shale, Hovey Channel, southern Permian basin, west Texas  

Science Conference Proceedings (OSTI)

The Upper Devonian Woodford Shale in the Hovey Channel area, southern Permian basin, is 50 m thick and composed largely of brown to black, pyritic, spore-bearing, organic-rich, fissile shale an chert. Total organic carbon, distillable hydrocarbons, genetic potential, organic carbon index, hydrogen index, temperature of maximum hydrocarbon generation, and kerogen transformation index of the Woodford Shale suggest a matured to overmatured, gas-generating source bed. The total organic carbon content of the formation ranged from a low of 0.77% in the cherty samples to a high of 4.59% in a shaley sample, averaging 2.18%. Distillable hydrocarbon content of the samples is fairly high (averaging 1.72 mg HC/gm{degree} rock), varying from 0.90 mg HC/gm{degree} rock to 3.22 mg HC/gm{degree} rock. Genetic potential evaluated in terms of both residual and total generative potential showed above average potential, averaging 3.25 mg HC/gm{degree} rock for the residual and 4.90 mg HC/gm{degree} rock for the total, respectively. Live organic carbon index values ranged from 11-28%, characterizing the formation as a moderate to good source bed. Hydrogen index values ranged from 73 mg HC/gm{degree} C org to 155 mg HC/gm{degree} C org, suggesting overmaturity and gas-generation potential of the source bed. Temperature of maximum hydrocarbon generation values and kerogen transformation ratio values (averaging 0.34) also indicate overmatured nature of the Woodford Shale.

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

E-Print Network (OSTI)

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

Three main areas of oil-shale occurrence have been studied in detail: the Elko area, Pinon Range area, and Coal Mine Canyon. Geologic mapping, stratigraphic studies, and sampling to delimit the lateral extent of the oil shale deposits were in progress prior to the cooperative agreement with Nevada DOE. These surface geologic studies have been summarized in this report. The results of surface geologic studies conducted near Elko suggested that the Elko area represented the best and most accessible oil-shale deposits; therefore, the Elko area was selected as the site of a shallow exploratory drilling program. Essential to this study was the obtaining of fresh, unweathered oil-shale samples from the Elko area. The samples were obtained from the core-drilling program and tested for oil yield by Fischer assays. The oil yields determined from these samples, together with the geology have provided an improved basis for resource estimates for the oil-shale deposit at Elko. In addition to the more detailed field studies, a literature survey was conducted to develop a bibliography related to oil shale in Nevada and to use as a basis for identifying other oil-shale occurrences. The literature search was also extended to include information on petroleum source rocks that contain organic-rich shales with possible potential as additional oil-shale resources. The annotated bibliography is included in the appendix. 88 refs., 8 figs., 5 tabs.

Ostracode distribution in Late Pennsylvanian Finis Shale cyclothem  

SciTech Connect

Four successive intergrading ostracode biofacies characterize the Finis Shale cyclothem (Cisco Group, Virgilian) near Jacksboro, Texas. Composition of the ostracode biofacies parallels the distinct megafaunal assemblages ascribed by Boardman et al (1983) to changing oxygen concentrations, water depths, and salinity. Black, organic-rich, noncalcareous, fissile shales occur near the base of the Finis. This lithofacies is barren of ostracodes and megafauna, and is interpreted to represent a deeper water, anoxic environment. The overlying dark-gray, phosphatic shales contain a diminutive pyritic molluscan fauna with abundant ammonoids and a low-diversity ostracode assemblage dominated by Healdia, indicating a dysaerobic environment. The overlying lithofacies is a medium-gray, clay-rich, calcareous shale. The Megafauna is dominated by a brachiopod-bryzoan assemblage, and a diverse Ampissites-Kirkbya ostracode association occurs. This fauna represents a shallow depth, aerobic environment. The Amphissites-Kirkbya biofacies is overlain by a dark-gray calcareous shale with abundant megafossils of the fusulind-bryozoan facies of Boardman et al. This interval is dominated by a Bairdia-Amphissites-Kelletina ostracode assemblage, indicating a shallower aerobic environment. The shale is interrupted by the Jacksboro Limestone Member, an algal limestone deposited at or near wave base, which is covered by a thin intertidal sandstone. The cyclothem is capped by noncalcareous, brown silty shale. It contains a low-diversity ostracode assemblage dominated by Cavellina and a megafaunal assemblage characterized by Myalina, which represents a shallow, brackish water environment.

Porosity and permeability of Eastern Devonian gas shale  

SciTech Connect

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

Evolution of porosity and geochemistry in Marcellus Formation black shale during weathering  

Science Conference Proceedings (OSTI)

Soils developed on the Oatka Creek member of the Marcellus Formation in Huntingdon, Pennsylvania were analyzed to understand the evolution of black shale matrix porosity and the associated changes in elemental and mineralogical composition during infiltration of water into organic-rich shale. Making the reasonable assumption that soil erosion rates are the same as those measured in a nearby location on a less organic-rich shale, we suggest that soil production rates have on average been faster for this black shale compared to the gray shale in similar climate settings. This difference is attributed to differences in composition: both shales are dominantly quartz, illite, and chlorite, but the Oatka Creek member at this location has more organic matter (1.25 wt.% organic carbon in rock fragments recovered from the bottom of the auger cores and nearby outcrops) and accessory pyrite. During weathering, the extremely low-porosity bedrock slowly disaggregates into shale chips with intergranular pores and fractures. Some of these pores are eitherfilled with organic matter or air-filled but remain unconnected, and thus inaccessible to water. Based on weathering bedrock/soil profiles, disintegration is initiated with oxidation of pyrite and organic matter, which increases the overall porosity and most importantly allows water penetration. Water infiltration exposes fresh surface area and thus promotes dissolution of plagioclase and clays. As these dissolution reactions proceed, the porosity in the deepest shale chips recovered from the soil decrease from 9 to 7% while kaolinite and Fe oxyhydroxides precipitate. Eventually, near the land surface, mineral precipitation is outcompeted by dissolution or particle loss of illite and chlorite and porosity in shale chips increases to 20%. As imaged by computed tomographic analysis, weathering causes i) greater porosity, ii) greater average length of connected pores, and iii) a more branched pore network compared to the unweathered sample. This work highlights the impact of shale water O2interactions in near-surface environments: (1) black shale weathering is important for global carbon cycles as previously buried organic matter is quickly oxidized; and (2) black shales weather more quickly than less organic- and sulfide-rich shales, leading to high porosity and mineral surface areas exposed for clay weathering. The fast rates of shale gas exploitation that are ongoing in Pennsylvania, Texas and other regions in the United States may furthermore lead to release of metals to the environment if reactions between water and black shale are accelerated by gas development activities in the subsurface just as they are by low-temperature processes in ourfield study.

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

Science Conference Proceedings (OSTI)

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

Porosity and permeability of eastern Devonian gas shale  

Science Conference Proceedings (OSTI)

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

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

Oil shale resources of the Naval Oil Shale Reserve No. 1, Colorado  

SciTech Connect

The resource of potential oil represented by Green River Formation oil shale on Naval Oil Shale Reserve No. 1 (NOSR No. 1) in the southeast corner of Colorado's Piceance Creek Basin is evaluated in detail. NOSR No. 1 is the site of intensive long-term oil-shale development studies and is the source of innumerable oil-shale samples for all manner of testing. A brief history of these studies is presented. This oil-shale resource is defined from oil-yield assay data on 33 cores plotted as histograms and correlated into cross sections. Contour maps of thickness, richness and oil resource in place are presented for the Mahogany Zone, the rich zone in the Mahogany zone, and for 2 units beneath and 5 units above the Mahogany zone. Total oil shale resource on NOSR No. 1 is 20.4 billion barrels of which 17.4 billion barrels are particularly suitable for development by vertical modified in-place processes. A previously unknown Mahogany zone outcrop providing much additional development access is described. Now under sole control of the US Department of Energy (DOE), NOSR No. 1 offers DOE a unique site for oil shale testing and development.

Oil shale commercialization study  

SciTech Connect

Ninety four possible oil shale sections in southern Idaho were located and chemically analyzed. Sixty-two of these shales show good promise of possible oil and probable gas potential. Sixty of the potential oil and gas shales represent the Succor Creek Formation of Miocene age in southwestern Idaho. Two of the shales represent Cretaceous formations in eastern Idaho, which should be further investigated to determine their realistic value and areal extent. Samples of the older Mesozonic and paleozoic sections show promise but have not been chemically analyzed and will need greater attention to determine their potential. Geothermal resources are of high potential in Idaho and are important to oil shale prospects. Geothermal conditions raise the geothermal gradient and act as maturing agents to oil shale. They also might be used in the retorting and refining processes. Oil shales at the surface, which appear to have good oil or gas potential should have much higher potential at depth where the geothermal gradient is high. Samples from deep petroleum exploration wells indicate that the succor Creek shales have undergone considerable maturation with depth of burial and should produce gas and possibly oil. Most of Idaho's shales that have been analyzed have a greater potential for gas than for oil but some oil potential is indicated. The Miocene shales of the Succor Creek Formation should be considered as gas and possibly oil source material for the future when technology has been perfectes. 11 refs.

Distribution and origin of sulfur in Colorado oil shale  

SciTech Connect

The sulfur content of 1,225 samples of Green River oil shale from two core holes in the Piceance Creek Basin, Colorado, ranges from nearly 0 to 4.9 weight percent. In one core hole, the average sulfur content of a sequence of oil shale 555 m thick, which represents nearly the maximum thickness of oil shale in the basin, is 0.76 weight percent. The vertical distribution of sulfur through the oil shale is cyclic. As many as 25 sulfur cycles have lateral continuity and can be traced between the core holes. Most of the sulfur resides in iron sulfides (pyrite, marcasite, and minor. pyrrhotite), and small amounts are organically bound in kerogen. In general, the concentration of sulfur correlates moderately with oil shale yield, but the degree of association ranges from quite high in the upper 90 m of the oil shale sequence to low or none in the leached zone and in illitic oil shale in the lower part of the sequence. Sulfur also correlates moderately with iron in the carbonate oil shale sequence, but no correlation was found in the illitic samples. Sulfide mineralization is believed to have occurred during early and late stages of diagenesis, and after lithification, during development of the leached zone. Significant amounts of iron found in ankeritic dolomite and in illite probably account for the lack of a strong correlation between sulfur and iron.

Present trends in Estonian-Russian work on oil shale  

SciTech Connect

The Estonian oil-shale basin lies near Leningrad. The Baltic region of Russia has always been deficient in fuel and hydroelectric power, and in the post-war years Russia has used oil shale of occupied Estonia to meet these 2 demands. Kukersite oil shale is found in thick calcareous Late Ordovician beds of marine origin which lie throughout the basin at depths varying form 0 to 300 m. Shale layers with thicknesses from 0.6 to 0.7 m and up are considered commercial. Shale beds with an aggregate thickness of 3 m are also common throughout the basin. The Russians have developed more than 10 large underground mines and several open-pit mines whose total annual output in 1966 reached 25 million metric tons. Russia's new energy-chemical and complex-utilization of oil shale processing may offer some economic advantage. These 2 fields--the chemical processing and the waste product utilization--are the areas where the Russians are doing much research, developing new methods, and adapting many petrochemical technologies to shale-chemical processes. This information and the Russian experience with the successful new solid-heat exchanger large-capacity retort should be quite useful to the U.S.A. (49 refs.)

Oil shale data book  

SciTech Connect

The Oil Shale Data Book has been prepared as a part of its work under DOE Management Support and Systems Engineering for the Naval Oil Shale Reserves Predevelopment Plan. The contract calls for the preparation of a Master Development Plan for the Reserves which comprise some 145,000 acres of oil shale lands in Colorado and Utah. The task of defining the development potential of the Reserves required that the resources of the Reserves be well defined, and the shale oil recovery technologies that are potentially compatible with this resource be cataloged. Additionally, processes associated with shale oil recovery like mining, materials handling, beneficiation, upgrading and spent shale disposal have also been cataloged. This book, therefore, provides a ready reference for evaluation of appropriate recovery technologies and associated processes, and should prove to be valuable for many oil shale activities. Technologies that are still in the process of development, like retorting, have been treated in greater detail than those that are commercially mature. Examples of the latter are ore crushing, certain gas clean-up systems, and pipeline transportation. Emphasis has been on documenting available design information such as, maximum module size, operation conditions, yields, utility requirements, outlet gas compositions, shale oil characteristics, etc. Cost information has also been included where available.

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

Science Conference Proceedings (OSTI)

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

Refining of shale oil  

DOE Green Energy (OSTI)

The refining of shale oil is reviewed to assess the current state-of-the-art, especially as to the avaiability of technology suitable for operation on a commercial scale. Oil shale retorting processes as they affect the quality of the crude shale oil for refining, exploratory research on the character and refining of shale oil, and other published refining background leading to the present status are discussed. The initial refining of shale oil requires the removal of a large concentration of nitrogen, an added step not required for typical petroleum crude oils, and recently published estimates show that the total cost of refining will be high. Specific technoloy is reported by industry to be technically proven and available for commercial-scale refining. Although the refining will be more costly than that of petroleum, the viability of a shale oil industry will also be affected greatly by the technology and costs of producing the crude shale oil, environmental costs, and future price and tax treatment, and these are outside the scope of this study of refining.

Market assessment for shale oil  

DOE Green Energy (OSTI)

This study identified several key issues on the cost, timeliness, and ease with which shale oil can be introduced into the United States' refining system. The capacity of the existing refining industry to process raw shale oil is limited by the availability of surplus hydrogen for severe hydrotreating. The existing crude oil pipeline system will encounter difficulties in handling raw shale oil's high viscosity, pour point, and contaminant levels. The cost of processing raw shale oil as an alternate to petroleum crude oil is extremely variable and primarily dependent upon the percentage of shale oil run in the refinery, as well as the availability of excess hydrogen. A large fraction of any shale oil which is produced will be refined by the major oil companies who participate in the shale oil projects and who do not anticipate problems in processing the shale oil in their refineries. Shale oil produced for sale to independent refiners will initially be sold as boiler fuel. A federal shale oil storage program might be feasible to supplement the Strategic Petroleum Reserve. Based on refinery configurations, hydrogen supply, transportation systems, and crude availability, eleven refineries in Petroleum Administration for Defense Districts (PADDs) 2A and 2B have been identified as potential processors of shale oil. Based on refining technology and projected product demands to the year 2000, shale oil will be best suited to the production of diesel fuel and jet fuel. Tests of raw shale oil in boilers are needed to demonstrate nitrogen oxide emissions control.

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: Technology status report  

Science Conference Proceedings (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.

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.

Fractured shale reservoirs: Towards a realistic model  

Science Conference Proceedings (OSTI)

Fractured shale reservoirs are fundamentally unconventional, which is to say that their behavior is qualitatively different from reservoirs characterized by intergranular pore space. Attempts to analyze fractured shale reservoirs are essentially misleading. Reliance on such models can have only negative results for fractured shale oil and gas exploration and development. A realistic model of fractured shale reservoirs begins with the history of the shale as a hydrocarbon source rock. Minimum levels of both kerogen concentration and thermal maturity are required for effective hydrocarbon generation. Hydrocarbon generation results in overpressuring of the shale. At some critical level of repressuring, the shale fractures in the ambient stress field. This primary natural fracture system is fundamental to the future behavior of the fractured shale gas reservoir. The fractures facilitate primary migration of oil and gas out of the shale and into the basin. In this process, all connate water is expelled, leaving the fractured shale oil-wet and saturated with oil and gas. What fluids are eventually produced from the fractured shale depends on the consequent structural and geochemical history. As long as the shale remains hot, oil production may be obtained. (e.g. Bakken Shale, Green River Shale). If the shale is significantly cooled, mainly gas will be produced (e.g. Antrim Shale, Ohio Shale, New Albany Shale). Where secondary natural fracture systems are developed and connect the shale to aquifers or to surface recharge, the fractured shale will also produce water (e.g. Antrim Shale, Indiana New Albany Shale).

Shale oil recovery process

A process of producing within a subterranean oil shale deposit a retort chamber containing permeable fragmented material wherein a series of explosive charges are emplaced in the deposit in a particular configuration comprising an initiating round which functions to produce an upward flexure of the overburden and to initiate fragmentation of the oil shale within the area of the retort chamber to be formed, the initiating round being followed in a predetermined time sequence by retreating lines of emplaced charges developing further fragmentation within the retort zone and continued lateral upward flexure of the overburden. The initiating round is characterized by a plurality of 5-spot patterns and the retreating lines of charges are positioned and fired along zigzag lines generally forming retreating rows of W's. Particular time delays in the firing of successive charges are disclosed.

Apparatus for oil shale retorting  

DOE Patents (OSTI)

A cascading bed retorting process and apparatus in which cold raw crushed shale enters at the middle of a retort column into a mixer stage where it is rapidly mixed with hot recycled shale and thereby heated to pyrolysis temperature. 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.

Production of tectonically caused overpressures in carbonates by using resistivity and bulk density of associated shales  

SciTech Connect

In tectonically caused overpressured carbonate reservoirs associated with thick shale beds (e.g., 50 m and more), several shale properties can be used as predictive techniques: low porosities, high acoustic (sonic) velocities, high resistivities, and high bulk densities. The reason these properties are used is because the greater the degree of overcompaction (due to tectonic forces), the greater the amount of water squeezed from the shales, which, in turn, overpressures the associated reservoirs. Two case studies from the Soviet Union and Iran illustrate this occurrence. For comparison purposes, the prediction of overpressures caused by undercompaction (e.g., due to rapid sedimentation) using conventional overpressure indicators, such as resistivity, acoustic and density logs, and bulk density of shale cuttings, are reviewed and illustrated via a typical Tertiary sand/shale sequence.

Microstructures and Rheology of a Limestone-Shale Thrust Fault  

E-Print Network (OSTI)

The Copper Creek thrust fault in the southern Appalachians places Cambrian over Ordovician sedimentary strata. The fault accommodated displacement of 15-20 km at 100-180 C. Along the hanging wall-footwall contact, microstructures within a ~2 cm thick calcite and shale shear zone suggest that calcite, not shale, controlled the rheology of the shear zone rocks. While shale deformed brittley, plasticity-induced fracturing in calcite resulted in ultrafine-grained (shale into the shear zone, shows the evolution of rheology within the shear zone. Sedimentary laminations 1 cm below the shear zone are cut by minor faults, stylolites, and fault-parallel and perpendicular calcite veins. At vein intersections, calcite grain size is reduced (to ~0.3 ?m), and microstructures include inter-and-intragranular fractures, four-grain junctions, and interpenetrating boundaries. Porosity rises to 6 percent from shale clasts (5-350 ?m) lie within an ultrafine-grained calcite (shale matrix. Ultrafinegrained calcite (shale. Calcite vein microstructures suggest veins continued to form during deformation. Fractures at twin-twin and twin-grain boundary intersections suggest grain size reduction by plasticity-induced fracturing, resulting in <1 ?m grains. Interpenetrating boundaries, four-grain junctions, and no LPO indicate the ultrafine-grained calcite deformed by viscous grain boundary sliding. The evolution of the ultrafine-grain shear zone rocks by a combination of plastic and brittle processes and the deformation of the interconnected network of ultrafine-grained calcite by viscous GBS enabled a large displacement along a narrow fault zone.

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

Science Conference Proceedings (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 are being sampled to collect CO{sub 2} adsorption isotherms. Sidewall core samples have been acquired to investigate CO{sub 2} displacement of methane. An elemental capture spectroscopy log has been 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 4.62 percent. CO{sub 2} adsorption capacities at 400 psi range from a low of 19 scf/ton in less organic-rich zones to more than 86 scf/ton in the Lower Huron Member of the shale. 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.

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

Solar retorting of oil shale  

DOE Green Energy (OSTI)

A detailed analysis of technical and economic factors solar retorting of oil shale shows that such a process should be technically feasible and, depending on the grade of the shale, should improve the fuel yield from the oil shale by 10 to 40%, compared to one of the best competing surface ay for the incremental processes. The improved oil yield should more than pay for the incremental cost associated with adding the solar collection system. An experiment is described in which solar energy is used to retort oil shale, and the experimental results show that yields of better than 110% Fischer Assay are achievable. An advanced design for a solar oil-shale retort is also discussed.

Resource appraisal of three rich oil-shale zones in the Green River Formation, Piceance Creek Basin, Colorado  

SciTech Connect

The main oil-shale-bearing member of the Eocene Green River Formation, the Parachute Creek Member, contains several distinct rich oil-shale zones that underlie large areas of Piceance Creek Basin in NW. Colorado. Three of these have been selected for an oil-shale resource-appraisal study. Two over-lie and one underlies the main saline zone in the Parachute Creek Member. The uppermost of these zones, the Mahogany Zone, is in the upper third of the Parachute Creek Member/ it ranges in thickness from less than 75 to more than 225 ft and is the most persistent oil- shale unit in the Green River Formation underlying an area of more than 1,200 sq miles in the Piceance Creek Basin. The second rich zone is separated from the Mahogany Zone by a variable thickness of sandstone, siltstone, or low- grade oil shale. This zone attains a maximum thickness of more than 250 ft and underlies an area of more than 700 sq miles. The third rich oil-shale zone is in the lower third of the Parachute Creek Member. It underlies an area of about 300 sq miles near the depositional center of the Piceance Creek Basin and attains a thickness of more than 150 ft. The 3 rich oil-shale zones have total resources of 317 billion bbl of oil in the areas appraised.

Intensive pre-project feasibility and engineering studies begun in 1979 have produced an outline plan for development of a major project for production of shale oil from private lands in the Piceance Basin in western Colorado. This outline plan provides a blueprint for the development of a 28,000 acre holding on Clear Creek in Garfield County, Colorado on property acquired by Standard Oil of California in the late 1940's and early 1950's. The paper describes these planning activities and the principal features of a proposed $5 billion project to develop facilities for production of 100,000 barrels per day of synthetic crude from oil shale. Subjects included are resource evaluation, environmental baseline studies, plans for acquisition of permits, plans for development of required retorting and mining technology and a preliminary description of the commercial project which will ultimately emerge from these activities. General financial impact of the project and the case for additional tax incentives to encourage it will be described.

NATURAL GAS FROM SHALE: Questions and Answers  

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

Where is shale gas found Where is shale gas found in the United States? Shale gas is located in many parts of the United States. These deposits occur in shale "plays" - a set of discovered, undiscovered or possible natural gas accumulations that exhibit similar geological characteristics. Shale plays are located within large-scale basins or accumulations of sedimentary rocks, often hundreds of miles across, that also may contain other oil and gas resources. 1 Shale gas production is currently occurring in 16 states. 1 U.S. Government Accountability Office, Report to Congressional Requesters, "Oil and Gas: Information on Shale Resources, Development, and

Oil shale retorting method and apparatus  

SciTech Connect

Disclosed is an improved method and apparatus for the retorting of oil shale and the formation of spent oil shale having improved cementation properties. The improved method comprises passing feed comprising oil shale to a contacting zone wherein the feed oil shale is contacted with heat transfer medium to heat said shale to retorting temperature. The feed oil shale is substantially retorted to form fluid material having heating value and forming partially spent oil shale containing carbonaceous material. At least a portion of the partially spent oil shale is passed to a combustion zone wherein the partially spent oil shale is contacted with oxidizing gas comprising oxygen and steam to substantially combust carbonaceous material forming spent oil shale having improved cementation properties.

Oil shale combustion/retorting  

SciTech Connect

The Morgantown Energy Technology Center (METC) conducted a number of feasibility studies on the combustion and retorting of five oil shales: Celina (Tennessee), Colorado, Israeli, Moroccan, and Sunbury (Kentucky). These studies generated technical data primarily on (1) the effects of retorting conditions, (2) the combustion characteristics applicable to developing an optimum process design technology, and (3) establishing a data base applicable to oil shales worldwide. During the research program, METC applied the versatile fluidized-bed process to combustion and retorting of various low-grade oil shales. Based on METC's research findings and other published information, fluidized-bed processes were found to offer highly attractive methods to maximize the heat recovery and yield of quality oil from oil shale. The principal reasons are the fluidized-bed's capacity for (1) high in-bed heat transfer rates, (2) large solid throughput, and (3) selectivity in aromatic-hydrocarbon formation. The METC research program showed that shale-oil yields were affected by the process parameters of retorting temperature, residence time, shale particle size, fluidization gas velocity, and gas composition. (Preferred values of yields, of course, may differ among major oil shales.) 12 references, 15 figures, 8 tables.

Process and apparatus for oil shale retorting  

SciTech Connect

A process and apparatus are disclosed for the continuoua steady state retorting of ground oil shale in the absence of air. Retorting is accomplished by countercurrently contacting heated spent oil shale with fresh ground oil shale in a vessel from which air is excluded. The spent oil shale is heated by combustion of its carbonaceous residue to form a hot heat transfer medium which, when contacted with fresh oil shale in the retorting process, provides the energy for the recovery of hydrocarbons.

Shale oil cracking. 1. Kinetics  

DOE Green Energy (OSTI)

Experiments were conducted to determine kinetics for thermal cracking of shale oil vapor over shale. Cracking temperatures of 504 to 610/sup 0/C and residence times of 2 to 11 seconds were used. A first-order Arrhenius rate expression and stoichiometry were obtained. Also observed were changes in the oil quality. Cracking decreased the H/C ratio, increased the nitrogen content, and decreased the pour point of the oil. Gas-phase oil cracking is contrasted to liquid-phase oil coking as a loss mechanism in oil-shale retorting.

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

Science Conference Proceedings (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. 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.

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

SciTech Connect

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.

Oil shale deposits of Thailand  

SciTech Connect

Oil-shale deposits occur in several areas of Thailand. Perhaps the most important deposit occurs at Mae Sod in Tak Province, West Thailand. Other well-known deposits are Li in Lamphum Province, Ko Kha District, Lampang Province, and Krabi in the southern peninsular region. The geological age of all these deposits is late Tertiary, as demonstrated by the presence of the fossils from the oil shale of the Mae Sod series, e.g., fish of the Ostariophysian family Cyprinidae.

Solar retorting of oil shale  

DOE Green Energy (OSTI)

First, in an overview, we outline and discuss the potential applications of solar energy to the production of fuels. We show that, starting from a fossil feedstock, there are four areas in which solar energy can have a major impact in the production of fuels: in solar retorting of oil shale, in solar coal gasification, in solar steam flooding of oil fields, and in solar steam-reforming of methane. We performed a detailed technical and economic analysis of solar retorting of oil shale. The analysis shows that this solar process not only should be technically feasible but also should improve the fuel yield from the oil-shale feedstock by 10 to 40%, depending on the grade of the shale, compared to the most efficient competing (nonsolar) process. The improved oil yield should more than pay for the incremental cost associated with adding the solar collection system (field of focusing heliostats). The results from an experiment in which solar energy was used to retort oil shale show that yields of better than 110% Fischer Assay are achievable. An advanced design for a solar oil-shale retort is also presented.

Combuston method of oil shale retorting  

DOE Patents (OSTI)

A gravity flow, vertical bed of crushed oil shale having a two level injection of air and a three level injection of non-oxygenous gas and an internal combustion of at least residual carbon on the retorted shale. The injection of air and gas is carefully controlled in relation to the mass flow rate of the shale to control the temperature of pyrolysis zone, producing a maximum conversion of the organic content of the shale to a liquid shale oil. The parameters of the operation provides an economical and highly efficient shale oil production.

Method of enhancing yield from an in situ oil shale retort  

SciTech Connect

To recover liquid and gaseous products from a fragmented permeable mass of particles containing oil shale, a buffer zone containing retorted oil shale is established in the fragmented mass by passing a hot processing gas substantially free of free oxygen through at least a portion of the fragmented mass. Thereafter, a combustion zone is established in the buffer zone, and a combustion zone feed containing oxygen is introduced into the fragmented mass on the trailing side of the combustion zone. This advances the combustion zone through the fragmented mass and retorts oil shale in a retorting zone on the advancing side of the combustion zone. The thickness of the buffer zone is sufficient for reaction of most of the oxygen in the combustion zone feed with residual carbonaceous material in retorted oil shale in the buffer zone.

High efficiency shale oil recovery  

SciTech Connect

The overall project objective is to demonstrate the high efficiency of the Adams Counter-Current shale oil recovery process. The efficiency will first be demonstrated on a small scale, in the current phase, after which the demonstration will be extended to the operation of a small pilot plant. Thus the immediate project objective is to obtain data on oil shale retorting operations in a small batch rotary kiln that will be representative of operations in the proposed continuous process pilot plant. Although an oil shale batch sample is sealed in the batch kiln from the start until the end of the run, the process conditions for the batch are the same as the conditions that an element of oil shale would encounter in a continuous process kiln. Similar chemical and physical conditions (heating, mixing, pyrolysis, oxidation) exist in both systems.The two most important data objectives in this phase of the project are to demonstrate (1) that the heat recovery projected for this project is reasonable and (2) that an oil shale kiln will run well and not plug up due to sticking and agglomeration. The following was completed this quarter. (1) Twelve pyrolysis runs were made on five different oil shales. All of the runs exhibited a complete absence of any plugging, tendency. Heat transfer for Green River oil shale in the rotary kiln was 84.6 Btu/hr/ft[sup 2]/[degrees]F, and this will provide for ample heat exchange in the Adams kiln. (2) One retorted residue sample was oxidized at 1000[degrees]F. Preliminary indications are that the ash of this run appears to have been completely oxidized. (3) Further minor equipment repairs and improvements were required during the course of the several runs.

Bakken Shale Oil Production Trends  

E-Print Network (OSTI)

As the conventional reservoirs decrease in discovering, producing and reserving, unconventional reservoirs are more remarkable in terms of discovering, development and having more reserve. More fields have been discovered where Barnett Shale and Bakken Shale are the most recently unconventional reservoir examples. Shale reservoirs are typically considered self-sourcing and have very low permeability ranging from 10-100 nanodarcies. Over the past few decades, numerous research projects and developments have been studied, but it seems there is still some contention and misunderstanding surrounding shale reservoirs. One of the largest shale in the United State is the Bakken Shale play. This study will describe the primary geologic characteristics, field development history, reservoir properties,and especially production trends, over the Bakken Shale play. Data are available for over hundred wells from different companies. Most production data come from the Production Data Application (HDPI) database and in the format of monthly production for oil, water and gas. Additional 95 well data including daily production rate, completion, Pressure Volume Temperature (PVT), pressure data are given from companies who sponsor for this research study. This study finds that there are three Types of well production trends in the Bakken formation. Each decline curve characteristic has an important meaning to the production trend of the Bakken Shale play. In the Type I production trend, the reservoir pressure drops below bubble point pressure and gas releasingout of the solution. With the Type II production trend, oil flows linearly from the matrix into the fracture system, either natural fracture or hydraulic fracture. Reservoir pressure is higher than the bubble point pressure during the producing time and oil flows as a single phase throughout the production period of the well. A Type III production trend typically has scattering production data from wells with a different Type of trend. It is difficult to study this Type of behavior because of scattering data, which leads to erroneous interpretation for the analysis. These production Types, especially Types I and II will give a new type curve matches for shale oil wells above or below the bubble point.

Multiphase flow analysis of oil shale retorting  

DOE Green Energy (OSTI)

Several multiphase phenomena occur during oil shale retorting. An analysis is presented of two of these processes including condensation of oil shale vapor and oscillations of pressure in oil shale blocks through cracked bedding planes. Energy conservation equations for oil shale retorting, which include the effects associated with condensation of oil, are derived on the basis of two phase flow theory. It is suggested that an effective heat capacity associated with the latent heat of condensation should be included in the modeling of simulated modified in-situ oil shale retorting. A pressure propagation equation for fast transients in oil shale cracks has been derived and examined in view of existing experimental data. For slow processes, a limiting solution for maximum pressure in oil shale rocks has been obtained. Generation of high pressures in rocks by thermal or other means may lead to rock fracture which may be taken advantage of in modified in-situ oil shale processing.

LLNL oil shale project review  

Science Conference Proceedings (OSTI)

Livermore's oil shale project is funded by two budget authorities, two thirds from base technology development and one third from environmental science. Our base technology development combines fundamental chemistry research with operation of pilot retorts and mathematical modeling. We've studied mechanisms for oil coking and cracking and have developed a detailed model of this chemistry. We combine the detailed chemistry and physics into oil shale process models (OSP) to study scale-up of generic second generation Hot-Recycled-Solid (HRS) retorting systems and compare with results from our 4 tonne-per-day continuous-loop HRS pilot retorting facility. Our environmental science program focuses on identification of gas, solid and liquid effluents from oil shale processes and development of abatement strategies where necessary. We've developed on-line instruments to quantitatively measure trace sulfur and nitrogen compounds released during shale pyrolysis and combustion. We've studied shale mineralogy, inorganic and organic reactions which generate and consume environmentally sensitive species. Figures, references, and tables are included with each discussion.

High-Temperature Nuclear Reactors for In-Situ Recovery of Oil from Oil Shale  

Science Conference Proceedings (OSTI)

The world is exhausting its supply of crude oil for the production of liquid fuels (gasoline, jet fuel, and diesel). However, the United States has sufficient oil shale deposits to meet our current oil demands for {approx}100 years. Shell Oil Corporation is developing a new potentially cost-effective in-situ process for oil recovery that involves drilling wells into oil shale, using electric heaters to raise the bulk temperature of the oil shale deposit to {approx}370 deg C to initiate chemical reactions that produce light crude oil, and then pumping the oil to the surface. The primary production cost is the cost of high-temperature electrical heating. Because of the low thermal conductivity of oil shale, high-temperature heat is required at the heater wells to obtain the required medium temperatures in the bulk oil shale within an economically practical two to three years. It is proposed to use high-temperature nuclear reactors to provide high-temperature heat to replace the electricity and avoid the factor-of-2 loss in converting high-temperature heat to electricity that is then used to heat oil shale. Nuclear heat is potentially viable because many oil shale deposits are thick (200 to 700 m) and can yield up to 2.5 million barrels of oil per acre, or about 125 million dollars/acre of oil at $50/barrel. The concentrated characteristics of oil-shale deposits make it practical to transfer high-temperature heat over limited distances from a reactor to the oil shale deposits. (author)

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.

The mechanical properties of oil shale have been under examination at Sandia since 1975 in a program which has involved laboratory and field experimentation along with complementary analytical activities. The dependence of the fragmentation phenomenon on strain rate is important in explosive applications because strain rates realized in typical blasting events extend over a wide range. The model has been used to calculate a variety of explosive geometries in oil shale, with results compared to small- and large-scale experiments, including a small block test with 80 g of explosive and a field test with 5 kg explosive.

A Study of the Dielectric Properties of Dry and Saturated Green River Oil Shale  

Science Conference Proceedings (OSTI)

We measured dielectric permittivity of dry and fluid-saturated Green River oil shale samples over a frequency range of 1 MHz to 1.8 GHz. Dry sample measurements were carried out between room temperature and 146 C, saturated sample measurements were carried out at room temperature. Samples obtained from the Green River formation of Wyoming and from the Anvil Points Mine in Colorado were cored both parallel and perpendicular to layering. The samples, which all had organic richness in the range of 10-45 gal/ton, showed small variations between samples and a relatively small level of anisotropy of the dielectric properties when dry. The real and imaginary part of the relative dielectric permittivity of dry rock was nearly constant over the frequency range observed, with low values for the imaginary part (loss factor). Saturation with de-ionized water and brine greatly increased the values of the real and imaginary parts of the relative permittivity, especially at the lower frequencies. Temperature effects were relatively small, with initial increases in permittivity to about 60 C, followed by slight decreases in permittivity that diminished as temperature increased. Implications of these observations for the in situ electromagnetic, or radio frequency (RF) heating of oil shale to produce oil and gas are discussed.

Material balance assay of Devonian gas shale  

DOE Green Energy (OSTI)

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

Oil-shale utilization at Morgantown, WV  

Science Conference Proceedings (OSTI)

Fully aware of the nation's need to develop high-risk and long-term research in eastern oil-shale and low-grade oil-shale utilization in general, the US DOE/METC initiated an eastern oil-shale characterization program. In less than 3 months, METC produced shale oil from a selected eastern-US oil shale with a Fischer assay of 8.0 gallons/ton. In view of the relatively low oil yield from this particular oil shale, efforts were directed to determine the process conditions which give the highest oil yield. A 2-inch-diameter electrically heated fluidized-bed retort was constructed, and Celina oil shale from Tennessee was selected to be used as a representative eastern oil shale. After more than 50 runs, the retorting data were analyzed and reviewed and the best oil-yield operating condition was determined. In addition, while conducting the oil-shale retorting experiments, a number of technical problems were identified, addressed, and overcome. Owing to the inherent high rates of heat and mass transfers inside the fluidized bed, the fluidized-bed combustor and retorting appear to be a desirable process technology for an effective and efficient means for oil-shale utilization. The fluidized-bed operation is a time-tested, process-proven, high-throughput, solid-processing operation which may contribute to the efficient utilization of oil-shale energy.

Enriching off gas from oil shale retort  

SciTech Connect

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

NATURAL GAS FROM SHALE: Questions and Answers  

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

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

Converting Chattanooga oil shale to synthetic liquid fuel. Phase I. Final report. [Tennessee  

SciTech Connect

The Chattanooga Shale is widely distributed in Tennessee and has been known as a potential source of shale oil and strategic minerals, particularly uranium, for many years. It was studied in the late 1940's as a source of uranium. The shale varies in color from light gray to black. The shale is of the Devonian Age and occurs under the Maury formation and above the Leipers limestone. It exists as the Gassaway and Dowelltown members. Generally, the combined thickness of these two members in the seven-county study ranged in thickness from about 26 feet to greater than 34 feet. The overall intent of this study was to identify the extent of the Chattanooga shale in Tennessee, characterize its properties, review its potential as an oil producer in terms of present-day technologies, and to assess interest in the private sector for development and commercialization. This report contains the results of this six-month study. 28 figures, 58 tables.

High efficiency shale oil recovery  

SciTech Connect

The overall project objective is to demonstrate the high efficiency of the Adams Counter-Current shale oil recovery process. The efficiency will first be demonstrated at bench-scale, in the current phase, after which the demonstration will be extended to the operation of a small pilot plant. Thus the immediate project objective is to obtain data on oil shale retorting operations in a small batch rotary kiln that will be representative of operations in the proposed continuous process pilot plant. Although a batch oil shale sample will be sealed in the batch kiln from the start until the end of the run, the process conditions for the batch will be the same as the conditions that an element of oil shale would encounter in a large continuous process kiln. For example, similar conditions of heat-up rate (20 deg F/min during the pyrolysis), oxidation of the residue and cool-down will prevail for the element in both systems. This batch kiln is a unit constructed in a 1987 Phase I SBIR tar sand retorting project. The kiln worked fairly well in that project; however, the need for certain modifications was observed. These modifications are now underway to simplify the operation and make the data and analysis more exact. The agenda for the first three months of the project consisted of the first of nine tasks and was specified as the following four items: 1. Sample acquisition and equipment alteration: Obtain seven oil shale samples, of varying grade each 10 lb or more, and samples of quartz sand. Order equipment for kiln modification. 3. Set up and modify kiln for operation, including electric heaters on the ends of the kiln. 4. Connect data logger and make other repairs and changes in rotary batch kiln.

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

Science Conference Proceedings (OSTI)

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

Hugoniots of Colorado oil shale  

SciTech Connect

Standard experimental shock wave techniques were used to obtain Hugoniots of Anvil Points oil shale as functions of richness and orientation in the pressure regime encountered in the near-field region of an explosion. The shock response was found to be sensitive to kerogen content but independent of bedding orientation relative to the direction of shock propagation. A two-component model combining the inferred dynamic parameters for the end members (kerogen and mineral matrix) is adequate to predict the Hugoniots of oil shale of any arbitrary composition. Hence, the Hugoniots, as for other material properties, can be ultimately uniquely related to the oil yield. Preliminary dynamic results from samples obtained from other sites in Colorado and Wyoming indicate that this is generally true within the accuracy required for predictive explosive rock breakage calculations. 7 figures.

Shale Oil Value Enhancement Research  

Science Conference Proceedings (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.

Oil shale up-date  

SciTech Connect

The development of large domestic oil shale resources in an environmentally acceptable manner is technically feasible. Such development is approaching economic attractiveness. It is an essential step in attacking the major national problem: increasing oil imports. Several things have been impeding oil shale development. First, until recently there has been a lack of viable technology. Second, environmental regulations are becoming increasingly restrictive. These have become so unrealistic that the bare undeveloped ground in oil shale country fails to comply. Most of this area is now classified as a nonattainment area. The third reason is economic uncertainty. This relates to price and other governmental controls which make it impossible to predict future conditions with enough confidence to justify private investments. In an effort to overcome this uncertainty, while retaining the impeding controls, all types of governmental incentives and supports are being proposed by the Administration, the Congress, and the industry. This study highlights the current status of the more prominent technologies. It suggest that the next logical step in their advancement is the construction and operation of single full-size retorts or modules.

The gaseous feed mixture consists of an oxygen supplying gas and water vapor and is introduced into the combustion zone at a rate sufficient to maintain the temperature in the combustion zone within a predetermined range of temperatures above the retorting temperature of the oil shale in the in situ oil shale retort. The introduction of the gaseous feed mixture into the combustion zone generates combustion product gases which together with the portion of the gaseous feed mixture which does not take part in the combustion process, is called flue gas. The flue gas passes through the oil shale on the advancing side of the combustion zone, thereby retorting the oil shale to produce liquid and gaseous products. The liquid product and the retort off gas, which consists of gaseous product and flue gas, are withdrawn from the in situ oil shale retort at a point on the advancing side of the retorting zone.

Oil shale oxidation at subretorting temperatures  

SciTech Connect

Green River oil shale was air oxidized at subretorting temperatures. Off gases consisting of nitrogen, oxygen, carbon monoxide, carbon dioxide, and water were monitored and quantitatively determined. A mathematical model of the oxidation reactions based on a shrinking core model has been developed. This model incorporates the chemical reaction of oxygen and the organic material in the oil shale as well as the diffusivity of the oxygen into the shale particle. Diffusivity appears to be rate limiting for the oxidation. Arrhenius type equations, which include a term for oil shale grade, have been derived for both the chemical reaction and the diffusivity.

Developments in oil shale in 1983  

SciTech Connect

Oil shale development activities continued at a somewhat restricted pace during 1983. The activities reflect the continued soft economic environment in the petroleum industry. A limited number of projects are active, and research is continuing on processes, materials handling, mining techniques, and resource evaluation. Past oil shale development papers have highlighted resources and activities in several states in the eastern and western portions of the United States. This paper highlights Australian oil shale geology and developments and Canadian oil shale geology and developments. 5 figures, 1 table.

Shale recharge and production behavior of geopressured reservoirs  

DOE Green Energy (OSTI)

The reservoir simulator MUSHRM was used to study the conditions under which significant shale recharge may be expected. The calculations presented herein show that shale recharge is a strong function of the vertical shale permeability but is not greatly influenced by the shale compressibility. Significant shale recharge will occur only if the vertical shale permeability is at least of the order of 0.01 ..mu..d.

Hydrology of the Piceance Basin and its impact on oil shale development  

SciTech Connect

The Piceance Basin is a structural downwarp in NW. Colorado. The Green River Formation, the uppermost stratigraphic unit in the basin, contains the richest oil shale deposits in the U.S. The near-surface rocks are commonly jointed. The joint density is a function of the competency and thickness of the individual layers, the lateral distance to a free surface, and the depth below the surface. These joints provide permeable paths for the flow of ground water. Consequently, soluble elements in the rock have been leached, thereby enhancing the transmissivity by fracture enlargement. Thus, the oil-shale layers are part of the aquifer matrix, and the richest layers of oil shale occur between, below or are part of the basin's complex aquifer system. Well over 1 million acre-ft of potable water is contained in the Green River ground-water system.

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

Science Conference Proceedings (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.

Fluidized bed retorting of eastern oil shale  

SciTech Connect

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.

Assay products from Green River oil shale  

DOE Green Energy (OSTI)

Data from 66 material-balanced assays conducted at Lawrence Livermore National Laboratory, Laramie Energy Technology Center, and The Oil Shale Corporation were compiled and analyzed to determine the pyrolysis stoichiometry for Green River formation oil shales originating in and near the Mahogany zone. Shale samples came from four sites in Colorado and one in Utah, and ranged in oil content from 12 to 258 L/Mg (3 to 62 gal/ton). Average values and pairwise correlation coefficients are reported for all data (except sulfur analyses) available on the shales, e.g., elemental analyses of shales and oils, distribution of organic carbon in products, gas composition, and some ratios of elemental composition. The wide range of organic carbon contents made it possible to demonstrate the sensitivity of assay product distribution to oil shale grade. A linear correlation for shale grade as a function of weight percent organic carbon in raw shale is presented. An average stoichiometry for pyrolysis of the organic material is also calculated and compared with others available in the literature.

Multi-scale Detection of Organic and Inorganic Signatures Provides Insights into Gas Shale Properties and Evolution  

Science Conference Proceedings (OSTI)

Organic geochemical analyses, including solvent extraction or pyrolysis, followed by gas chromatography and mass spectrometry, are generally conducted on bulk gas shale samples to evaluate their source and reservoir properties. While organic petrology has been directed at unravelling the matrix composition and textures of these economically important unconventional resources, their spatial variability in chemistry and structure is still poorly documented at the sub-micrometre scale. Here, a combination of techniques including transmission electron microscopy and a synchrotron-based microscopy tool, scanning transmission X-ray microscopy, have been used to characterize at a multiple length scale an overmature organic-rich calcareous mudstone from northern Germany. We document multi-scale chemical and mineralogical heterogeneities within the sample, from the millimetre down to the nanometre-scale. From the detection of different types of bitumen and authigenic minerals associated with the organic matter, we show that the multi-scale approach used in this study may provide new insights into gaseous hydrocarbon generation/retention processes occurring within gas shales and may shed new light on their thermal history.

Oil shale retorting and retort water purification process  

SciTech Connect

An oil shale process is provided to retort oil shale and purify oil shale retort water. In the process, raw oil shale is retorted in an in situ underground retort or in an above ground retort to liberate shale oil, light hydrocarbon gases and oil shale retort water. The retort water is separated from the shale oil and gases in a sump or in a fractionator or quench tower followed by an API oil/water separator. After the retort water is separated from the shale oil, the retort water is steam stripped, carbon adsorbed and biologically treated, preferably by granular carbon adsorbers followed by activated sludge treatment or by activated sludge containing powdered activated carbon. The retort water can be granularly filtered before being steam stripped. The purified retort water can be used in various other oil shale processes, such as dedusting, scrubbing, spent shale moisturing, backfilling, in situ feed gas injection and pulsed combustion.

Gasification characteristics of eastern oil shale  

DOE Green Energy (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.

Simulated in situ retorting of oil shale in a controlled-state retort. I. Nitrogen atmosphere, interrupted runs  

DOE Green Energy (OSTI)

A series of experiments has been performed on Green River oil shale using the controlled-state retort, an electrically heated retort designed to simulate in situ retorting. Each experiment described was stopped when only part of the shale bed had been completely retorted. Retorting parameters investigated include heating rate, retorting advance rate, gas input flow rate, and maximum temperature. Oils were washed and bitumens were extracted from the partially retorted and unretorted oil shales. The oils and bitumens were examined by simulated distillation gas chromatography, the product gases were analyzed by mass spectroscopy, and the shales were subjected to elemental analysis. Results of the various analyses are presented and conclusions are drawn from the data concerning the way the product oil moves through the bed of unretorted shale. The effects of temperature, heating rate, gas flow rate, and breadth of retorting zone on oil film thickness and bitumen content; the effect of heating rate on organic carbon content in the retorted shale; and the effect breadth of retorting zone has on the boiling point distribution of oils and bitumens as related to distance from the retorting zone are discussed.

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.

Thermal Maturity and Organic Facies of Devonian Shales From Selected Wells  

SciTech Connect

An organic geochemical study was performed on core samples of the Devonian shale from wells in Ohio, Kentucky, and Illinois. The thermal maturity of the organic matter (kerogen) contained in the fine-grained sediments was investigated by vitrinite reflectance and kerogen coloration (Thermal Alteration Index). The results indicate that the organic matter has been thermally matured to the early stages of petroleum and associated gas generation. A suite of geochemical analyses designed to evaluate the organic richness, the hydrocarbon potential for gas, condensate, and/or oil, and the type of organic matter was performed on the samples analyzed for thermal maturity. In general, two types of organic facies were encountered. The rich organic facies (A) is characterized by abundant gas, gasoline, and gas-oil hydrocarbons, a high organic carbon content, and organic matter prone to gererate abundant oil and associated gas. Based on the geochemical data, a second type of organic facies (B) interbedded with the rich organic facies (A) was encountered in Kentucy and Ohio wells. Organic facies B consists of sediments relatively lean in organic carbon and gas-oil hydrocarbons, and abundant gas and gasoline hydrocarbons. In most cases, facies B is composed of woody and coaly types of kerogen. The woody-coaly kerogen is presumed to indicate a nonmarine derived depositional source prone to generate predominately gas (methane).

Review and analysis of oil shale technologies. Volume II. True in situ technology  

SciTech Connect

This volume is a technical review and economic analysis of current true in-situ shale technology. Three techniques involving different fracturing methods are compared. Key variables include air compression, drilling depth, drill hole diameter and pattern geometry, shale grade, shale bed thickness, and explosives requirements. Variables, process systems, and process steps defined for each fracturing technique are scaled up to a 64,000-bbl/day facility and costed to provide a basis for evaluating relative economic feasibility. Capital investment, capital depreciation, annual operating, and crude shale oil costs are estimated and compared. The economic evaluation reveals that the choice of fracturing technique does not have any significant effect on the crude oil shale prices estimated for the scaled-up facilities. The costs per barrel vary only about 10%, with the lowest being the facility using the wellbore springing-explosive technique at $19 and the highest being the facility using the underreaming-explosive technique at $21. From a technical standpoint, the combination of hydraulic fracturing and explosive rubblization has the best potential for improvement. A major finding in this evaluation is that high costs associated with compression of the injection gas and drilling strongly influence process economics and, subsequently, crude oil selling prices for all techniques. The actual amount of oil recovered or extracted from the shale is also a major economic factor. The study concludes that the logistics of a commercial operation and the inability to create adequate permeability and surface area by any of the three fracturing techniques evaluated appear to be limiting factors, and that current technology has little potential for technical or economic success. 25 tables, 17 figures.

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.

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

E-Print Network (OSTI)

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

Oil shale: a new set of uncertainties  

SciTech Connect

The discovery and delivery of North Sea oil has created an uncertain future for the British oil shale industry in spite of its lower price per barrel. While oil companies have long been interested in a secure shale oil source for chemical feedstocks, environmental concerns, mining difficulties, and inflated operating costs have counteracted the opportunity provided by the 1973 oil embargo. With the financial risks of oil shale mining and retorting too great for a single company, research efforts have shifted to a search for technologies that will be multistaged and less costly, such as in-situ mining, in-situ processing, and hydraulic fracturing. Successful testing and demonstration of these processes will determine the future commercial role of oil shales. 17 references and footnotes.

Overview of LASL oil shale program  

SciTech Connect

The Los Alamos Scientific Laboratory (LASL) is involved in a broad spectrum of oil shale-related activities for the US Department of Energy (DOE), including the bed preparation design of a modified in situ retort. This aspect of oil shale research has been identified by DOE as one of the limiting technologies impeding commerical, in situ development of oil shale. The retort bed must have uniform particle size, permeability, and void distributions to allow proper retorting and optimum resource recovery. Controlled fracturing using chemical explosives and carefully designed blasting schemes are the only feasible methods to attain this distribution. This approach to the bed preparation problem is a coordinated research program of explosives characterization, dynamic rock mechanics, predictive computer modeling, and field verification tests. The program is designed to develop the predictive fracturing capability required for the optimum rubbing of the shale.

Oil shale. environmental and health issues  

SciTech Connect

Environmental and health issues include the solid-waste disposal problem; the possibility of the release of toxic and carcinogenic constituents into the environment; water requirements in a water-poor area; the potential air pollution problems; the low resource utilization of some of the processes; and the relative energy production compared with energy input. Such issues arise from the fact that it takes 1.5 tons of oil shale to make 1 bbl of oil, which, for a 1 million bbl/day industry, would require the processing of 480 million tons/yr of shale and would produce 390 million tons/yr of spent shale. The various oil shale processing technologies are briefly described.

Gas collection system for oil shale retort  

SciTech Connect

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

In situ recovery of shale oil  

SciTech Connect

An in situ oil shale retort is formed in a subterranean oil shale deposit by excavating a columnar void having a vertically extending free face, drilling blasting holes adjacent to the columnar void and parallel to the free face, loading the blasting holes with explosive, and detonating the explosive in a single round to expand the shale adjacent to the columnar void toward the free face in layers severed in a sequence progressing away from the free face and to fill with fragmented oil shale the columnar void and the space in the in situ retort originally occupied by the expanded shale prior to the expansion. A room having a horizontal floor plan that coincides approximately with the horizontal cross section of the retort to be formed is excavated so as to intersect the columnar void. The blasting holes are drilled and loaded with explosive from the room. The room can lie above the columnar void, below the columnar void, or intermediate the ends of the columnar void. In one embodiment, the columnar void is cylindrical and the blasting holes are arranged in concentric rings around the columnar void. In another embodiment, the columnar void is a slot having one or more large parallel, planar vertical free faces, toward which the oil shale in the retort under construction can be explosively expanded. The blasting holes are arranged in planes parallel to these faces. The resulting retort generally has a cross section coinciding with the placement of the blasting holes and a height determined for the greater part by the vertical height of the columnar void. To form a retort having a large cross-sectional area, a plurality of columnar voids can be excavated and the shale in the retort expanded toward the respective columnar voids to form a continuous fragmented permeable mass of oil shale.

Devonian shale gas resource assessment, Illinois basin  

Science Conference Proceedings (OSTI)

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

Reverse combustion oil-shale retorting  

DOE Green Energy (OSTI)

Oil shale was retorted in a laboratory retort with the flame front and gas flow moving concurrently and countercurrently. Results indicate countercurrent flow produced a lower oil yield and a higher heating value of the retort gas than concurrent flow. Energy recovery from the oil shale was essentially the same when the retorting was done with either concurrent or countercurrent flame and gas movement. Laboratory results are compared with large scale retorts operated under similar conditions.

Environmental control costs for oil shale processes  

SciTech Connect

The studies reported herein are intended to provide more certainty regarding estimates of the costs of controlling environmental residuals from oil shale technologies being readied for commercial application. The need for this study was evident from earlier work conducted by the Office of Environment for the Department of Energy Oil Shale Commercialization Planning, Environmental Readiness Assessment in mid-1978. At that time there was little reliable information on the costs for controlling residuals and for safe handling of wastes from oil shale processes. The uncertainties in estimating costs of complying with yet-to-be-defined environmental standards and regulations for oil shale facilities are a critical element that will affect the decision on proceeding with shale oil production. Until the regulatory requirements are fully clarified and processes and controls are investigated and tested in units of larger size, it will not be possible to provide definitive answers to the cost question. Thus, the objective of this work was to establish ranges of possible control costs per barrel of shale oil produced, reflecting various regulatory, technical, and financing assumptions. Two separate reports make up the bulk of this document. One report, prepared by the Denver Research Institute, is a relatively rigorous engineering treatment of the subject, based on regulatory assumptions and technical judgements as to best available control technologies and practices. The other report examines the incremental cost effect of more conservative technical and financing alternatives. An overview section is included that synthesizes the products of the separate studies and addresses two variations to the assumptions.

Two-stage oil shale retorting process and disposal of spent oil shale  

SciTech Connect

Formation is excavated from an in situ oil shale retort site for forming at least one void within the retort site, leaving at least one remaining zone of unfragmented formation within the retort site adjacent such a void. The remaining zone is explosively expanded toward such a void for forming a fragmented permeable mass of formation particles containing oil shale in an in situ oil shale retort. Oil shale in the in situ retort is retorted to produce liquid and gaseous products, leaving a mass of spent oil shale particles in the in situ retort. Oil shale particles excavated from the in situ retort site are separately retorted, such as in a surface retorting operation, producing liquid and gaseous products and spent surface retorted oil shale particles. The spent surface retorted particles are disposed of by forming an aqueous slurry of the particles, and pumping the slurry into a spent in situ retort. In one embodiment, the aqueous slurry is introduced into a hot lower portion of the spent retort where contact with hot spent oil shale particles generates steam which, in turn, is withdrawn from the spent retort in usable form. In another embodiment, water from the aqueous slurry introduced into a spent in situ retort collects at a level within the retort. The water can be recovered by drilling a drainage hole upwardly from a lower level drift into the level within the spent retort where the water collects and draining the water through the drainage hole to the lower level drift for recovery.

Transport in shales and the design of improved water-based shale drilling fluids  

Science Conference Proceedings (OSTI)

Transport of water and ions in shales and its impact on shale stability were studied to facilitate the improvement of water-based muds as shale drilling fluids. Transport parameters associated with flows driven by gradients in pressure and chemical potential were quantified in key laboratory and full-scale experiments. The experimental results show that the low-permeability matrices of intact, clay-rich shales can act as imperfect or leaky membranes that will sustain osmotic flow of water. Moreover, the ability of shales to act as osmotic membranes is shown to provide a powerful new means for stabilizing these rocks when exposed to water-based drilling fluids. Guidelines are presented for effective exploitation of shale membrane action and induced osmotic flows through optimized water-based drilling fluid formulation. In addition, special attention is given to induced electro-osmotic water flow in shales driven by electric potential gradients, which may provide an exciting, new, environmentally benign means for stabilizing shale formations.

In-situ laser retorting of oil shale  

SciTech Connect

Oil shale formations were retorted in-situ and gaseous hydrocarbon products recovered by drilling two or more wells into an oil shale formation. After fracturing a region of oil shale formation by directing a high energy laser beam into one of the wells and focussing the laser beam into a region of oil shale formation from a laser optical system, compressed gas was forced into the well which supports combustion in the flame front ignited by laser beam, thereby retorting the oil shale and recovering gaseous hydrocarbon products which permeate through the fractured oil shale from one of the auxiliary wells.

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.

Impact of excavation technique on strength of oil shale pillars  

SciTech Connect

The load carrying capacity of oil shale pillars excavated by conventional blasting, presplit blasting, and mechanical mining is evaluated. The study was based on a comparison of in-situ vertical stresses and fractures obtained from overcoring horizontal holes in the Colony Mine, Piceance Creek Basin, Colorado. Results indicate that conventional blasting causes a zone of damage approximately 3 m (10 ft) thick with low stress distributions. Presplit blasting reduces damage significantly, and increases the load carrying capacity in the 3 m (10 ft) thick zone by 5.93 MPa (860 psi). Mechanical mining causes little or no rock damage, and an increase of 9.83 MPa (1425 psi) in strength in the same 3 m (10 ft) thick zone. An example of pillar design is given showing that the use of presplit blasting and mechanical mining techniques can increase the extraction ratio by at least three and five percent, respectively, as compared to conventional blasting. It is speculated that comparable increases in extraction should also occur due to increases in span dimensions.

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

Science Conference Proceedings (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.

Can We Accurately Model Fluid Flow Can We Accurately Model Fluid Flow in Shale? Can We Accurately Model Fluid Flow in Shale? 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.

Gulf Shale Oil Upgrading Process technology  

SciTech Connect

A description of the Gulf Shale Oil Hydrotreating Process, which is designed for upgrading full range shale oil to premium quality synthetic crude, is presented. The process consists of two sections: a low severity pretreating section which stabilizes the raw oil, removes iron, arsenic, trace metals and particulates, and sulfur; and a twostage, high severity hydrotreating section which completes the upgrading. The second section hydrotreats the bulk oil to a specified nitrogen content, allowing for a quality FCC feedstock in the 650F+ (343C+) residue. The main reactor effluent is flashed with subsequent hydrotreating of the flash vapor oil to achieve a low nitrogen level in the naphtha and middle distillate. The benefit of this flash configuration is hydrogen addition selectivity which maximizes syncrude quality while minimizing overall hydrogen consumption; this selectivity relationship is detailed. Finally, the product quality of the syncrudes produced with the Gulf Shale Oil Hydrotreating Process using shale oils derived from three different retort technologies and for Western and Eastern shales are discussed.

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.

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

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.

NATURAL GAS FROM SHALE: Questions and Answers  

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

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

Oil shale retorting and combustion system  

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.

Economic enhancement of Western shale oil upgrading  

DOE Green Energy (OSTI)

A proof-of-concept study for a novel shale oil refining process was undertaken. This project promises reduced upgrading costs, thereby making shale oil development more feasible for commercialization. The process consists of distillation of raw shale oil into a distillate and residue portion, cracking of the residue by hydropyrolysis, and selective hydrotreating of narrow boiling cuts from the total distillate. Based on models and experimental data, the end product slate is projected to be 34% naphtha, 57% middle distillate, and 10.3% atm residue + coke. Hydrogen addition is 1.3% or 800 scf/bbl. These results are considerably improved over conventional processing, which gives 14% naphtha, 41% middle distillate, and 48.2% residue + coke and hydrogen addition of 3.2% or 2000 scf/bbl. More quantitative data and preliminary economics will be obtained in the next phase of study. 13 refs., 3 figs., 6 tabs.

Geokinetics In Situ Shale Oil Recovery Project. Second annual report, March, 1979  

DOE Green Energy (OSTI)

The project is being conducted at a field site located 70 miles south of Vernal, Utah. Because of the remote location of the site, and its poor accessibility over unpaved roads, a fully self-contained field camp was constructed to support the project and provide living quarters for the field crew. Eighteen in-situ retorts have been constructed, ranging in size from 330 tons to 46,000 tons. Eleven of these retorts have been burned, and a total of 5400 barrels of shale oil have been recovered. Oil shale thicknesses of 30 feet, and cross-sectional areas of 3800 square feet have been successfully blasted. The results have been encouraging, and the project will continue to scale up its size of the operation in 1979.

Oil degradation during oil shale retorting. [Effects on oil yields from powdered shale  

DOE Green Energy (OSTI)

Recent experimental data demonstrating the effects of varied thermal histories on oil yield from powdered Colorado shale are reviewed. Losses in overall yield resulting from interruption of a rapid heating schedule with an isothermal holding period are directly related to the amounts of oil that are produced during the holding period. These amounts are also correlated with the inert gas flow rates required to raise the yields to the assay value. The results show that degradation of oil outside the shale particles is the major determinant of oil yield from powdered shale. Maximum thermal degradation rates are calculated from these data and compared with pyrolysis rates for petroleum fractions.

Why solar oil shale retorting produces more oil  

DOE Green Energy (OSTI)

A solar oil shale retorting process may produce higher oil yield than conventional processing. High oil yield is obtained for three reasons: oil carbonization inside of the shale is reduced, oil cracking outside of the shale is reduced, and oil oxidation is essentially eliminated. Unique capabilities of focused solar energy produce these advantages. An increase in yield will reduce the cost of mining and shale transportation per barrel of oil produced. These cost reductions may justify the increased processing costs that will probably be associated with solar oil shale retorting.

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

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

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

Morphological investigations of fibrogenic action of Estonian oil shale dust  

SciTech Connect

A review of morphological investigations carried out to clarify the pathogenicity of industrial dust produced in the mining and processing of Estonian oil shale is given. Histological examination of lungs of workers in the oil shale industry taken at necropsies showed that the inhalation of oil shale dust over a long period (more than 20 years) may cause the development of occupational pneumoconiotic changes in oil shale miners. The pneumoconiotic process develops slowly and is characterized by changes typical of the interstitial form of pneumoconiotic fibrosis in the lungs. Emphysematous changes and chronic bronchitis also occur. The average chemical content of oil shale as well as of samples of oil shale dust generated during mining and sorting procedures is given. The results of experiments in white rats are presented; these studies also indicate a mild fibrogenic action of Estonian oil shale dust.

Soil stabilization using oil-shale solid waste  

Science Conference Proceedings (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.

Studies of New Albany shale in western Kentucky. Final report  

Science Conference Proceedings (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 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.

Technically recoverable Devonian shale gas in Ohio  

SciTech Connect

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

Constraints on the commercialization of oil shale  

DOE Green Energy (OSTI)

The problems and prospects for the commercialization of oil shale from surface retorting are examined. Commercialization refers to the process of private sector adoption of a technology for general use after most of the technological uncertainties have been resolved. Three categories of constraints and uncertainties can be identified: technical constraints relating to the performance characteristics of the technology; economic constraints on the ability of the technology to yield an acceptable rate of return to investors; and institutional constraints that arise from the organizational and political context in which commercialization takes place. Because surface retorting involves relatively well understood technologies, this study deals almost exclusively with economic and institutional constraints. At the present time, a government commercialization effort for oil shale surface retorting would not be likely to result in a viable industry in this century. Alternative oil shale technologies such as modified in situ processes offer prospects of lower shale oil costs, but are less well developed. Data on modified in situ processes are not abundant enough as yet to permit serious estimates of commercial-scale costs. Consequently, government decisions regarding the commercialization of modified in situ technologies should await the completion of further technical tests and an independent definitive plant design.

Fast Track Reservoir Modeling of Shale Formations in the Appalachian Basin. Application to Lower Huron Shale in Eastern Kentucky  

Science Conference Proceedings (OSTI)

In this paper a fast track reservoir modeling and analysis of the Lower Huron Shale in Eastern Kentucky is presented. Unlike conventional reservoir simulation and modeling which is a bottom up approach (geo-cellular model to history matching) this new approach starts by attempting to build a reservoir realization from well production history (Top to Bottom), augmented by core, well-log, well-test and seismic data in order to increase accuracy. This approach requires creation of a large spatial-temporal database that is efficiently handled with state of the art Artificial Intelligence and Data Mining techniques (AI & DM), and therefore it represents an elegant integration of reservoir engineering techniques with Artificial Intelligence and Data Mining. Advantages of this new technique are a) ease of development, b) limited data requirement (as compared to reservoir simulation), and c) speed of analysis. All of the 77 wells used in this study are completed in the Lower Huron Shale and are a part of the Big Sandy Gas field in Eastern Kentucky. Most of the wells have production profiles for more than twenty years. Porosity and thickness data was acquired from the available well logs, while permeability, natural fracture network properties, and fracture aperture data was acquired through a single well history matching process that uses the FRACGEN/NFFLOW simulator package. This technology, known as Top-Down Intelligent Reservoir Modeling, starts with performing conventional reservoir engineering analysis on individual wells such as decline curve analysis and volumetric reserves estimation. Statistical techniques along with information generated from the reservoir engineering analysis contribute to an extensive spatio-temporal database of reservoir behavior. The database is used to develop a cohesive model of the field using fuzzy pattern recognition or similar techniques. The reservoir model is calibrated (history matched) with production history from the most recently drilled wells. The calibrated model is then further used for field development strategies to improve and enhance gas recovery.

Oil shale health and environment research  

DOE Green Energy (OSTI)

While there have been sporadic efforts to demonstrate certain shale oil extraction technologies in recent years, none of the techniques have been thoroughly analyzed to determine the extent of potential occupational health impacts and even those technologies that have been demonstrated cannot be regarded as typical of a scaled-up, fully mature industry. Industrial hygiene studies have served to identify operations within certain technologies where mitigating methods can and should be applied to protect the industrial populations. Judging from data developed by on-site sampling it is probable that, with the possible exception of MIS techniques, oil shale mining presents no unique problems that cannot be handled with state-of-the-art control procedures. The conditions that may exist in a mine where in situ retorts are being simultaneously prepared, burned and abandoned have not as yet been defined. The probability of combined exposures to spent shale dusts and fugitive emissions in the form of vapors and gases added to the potential for skin exposure to product oils and other liquid effluents raises more complex questions. It has been shown by both epidemiological evidence and experimental data gathered both in the US and in foreign industries that crude shale oil and some of its products carry a higher carcinogenic potential than most of the natural petroleums. Preliminary data suggest that this particular hazard may be almost self-eliminating if hydrotreating, in preparation for refining, is universally practiced. The determination of specific hazards should be done on a technology-specific basis since it is highly probable that the biological activity of most of the products and by-products of shale oil production is process-specific.

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

E-Print Network (OSTI)

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

Los Alamos environmental activities/oil shale effluents  

SciTech Connect

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.

Water management practices used by Fayetteville shale gas producers.  

SciTech Connect

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

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

SciTech Connect

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.

Plan for addressing issues relating to oil shale plant siting  

SciTech Connect

The Western Research Institute plan for addressing oil shale plant siting methodology calls for identifying the available resources such as oil shale, water, topography and transportation, and human resources. Restrictions on development are addressed: land ownership, land use, water rights, environment, socioeconomics, culture, health and safety, and other institutional restrictions. Descriptions of the technologies for development of oil shale resources are included. The impacts of oil shale development on the environment, socioeconomic structure, water availability, and other conditions are discussed. Finally, the Western Research Institute plan proposes to integrate these topics to develop a flow chart for oil shale plant siting. Western Research Institute has (1) identified relative topics for shale oil plant siting, (2) surveyed both published and unpublished information, and (3) identified data gaps and research needs. 910 refs., 3 figs., 30 tabs.

Analysis of low stress oil shale Hugoniots  

SciTech Connect

Analysis of low stress Hugoniot data on Anvil Points oil shale was accomplished through careful categorization of data depending upon density. Density is directly related to kerogen content and kerogen content is a strong variable in determining the Hugoniot. For a given density (kerogen content), the shock velocity-particle velocity data show a minimum in shock velocity believed related to yielding in the rock constituent of the oil shale. Low stress Hugoniot data blend smoothly with high pressure data. Further data selection permitted evaluation of the orientation dependence (approximately 15 percent in wave speed) of the shock velocity. Wave propagation speed in a direction normal to the bedding planes is less than that parallel to the bedding planes. A weak minimum in wave speed occurs between 0 and 45/sup 0/.
