    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

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

  5. Formation resistivity as an indicator of oil generation in black shales

    Black, organic-rich shales of Late Devonian-Early Mississippi age are present in many basins of the North American craton and, where mature, have significant economic importance as hydrocarbon source rocks. Examples drawn from the upper and lower shale members of the Bakken Formation, Williston basin, North Dakota, and the Woodford Shale, Anadarko basin, Oklahoma, demonstrate the utility of formation resistivity as a direct in-situ indicator of oil generation in black shales. With the onset of oil generation, nonconductive hydrocarbons begin to replace conductive pore water, and the resistivity of a given black-shale interval increases from low levels associated with thermal immaturity to values approaching infinity. Crossplots of a thermal-maturity index (R/sub 0/ or TTI) versus formation resistivity define two populations representing immature shales and shales that have generated oil. A resistivity of 35 ohm-m marks the boundary between immature and mature source rocks for each of the three shales studied. Thermal maturity-resistivity crossplots make possible a straightforward determination of thermal maturity at the onset of oil generation, and are sufficiently precise to detect subtle differences in source-rock properties. For example, the threshold of oil generation in the upper Bakken shale occurs at R/sub 0/ = 0.43-0.45% (TTI = 10-12). The threshold increases to R/sub 0/ = 0.48-0.51% (TTI = 20-26) in the lower Bakken shale, and to R/sub 0/ = 0.56-0.57% (TTI = 33-48) in the most resistive Woodford interval.

    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.

    We examined the hypothesis that sulfide drives arsenic mobilization from pyritic black shale by a sulfide-arsenide exchange and oxidation reaction in which sulfide replaces arsenic in arsenopyrite forming pyrite, and arsenide (As-1) is concurrently oxidized to soluble arsenite (As+3). This hypothesis was tested in a series of sulfide-arsenide exchange experiments with arsenopyrite (FeAsS), homogenized black shale from the Newark Basin (Lockatong formation), and pyrite isolated from Newark Basin black shale incubated under oxic (21% O2), hypoxic (2% O2, 98% N2), and anoxic (5% H2, 95% N2) conditions. The oxidation state of arsenic in Newark Basin black shale pyrite was determined using X-ray absorption-near edge structure spectroscopy (XANES). Incubation results show that sulfide (1 mM initial concentration) increases arsenic mobilization to the dissolved phase from all three solids under oxic and hypoxic, but not anoxic conditions. Indeed under oxic and hypoxic conditions, the presence of sulfide resulted in the mobilization in 48 h of 13-16 times more arsenic from arsenopyrite and 6-11 times more arsenic from isolated black shale pyrite than in sulfide-free controls. XANES results show that arsenic in Newark Basin black shale pyrite has the same oxidation state as that in FeAsS (-1) and thus extend the sulfide-arsenide exchange mechanism of arsenic mobilization to sedimentary rock, black shale pyrite. Biologically active incubations of whole black shale and its resident microorganisms under sulfate reducing conditions resulted in sevenfold higher mobilization of soluble arsenic than sterile controls. Taken together, our results indicate that sulfide-driven arsenic mobilization would be most important under conditions of redox disequilibrium, such as when sulfate-reducing bacteria release sulfide into oxic groundwater, and that microbial sulfide production is expected to enhance arsenic mobilization in sedimentary rock aquifers with major pyrite-bearing, black

    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

    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.

    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.

    The decay of {sup 187}Re to {sup 187}Os provides a tool for determining depositional ages of black shales. Re and Os concentrations and Os isotopic compositions of whole rock samples of the Bakken Shale, a Mississippian/Devonian boundary black shale, yield a whole rock isochron with an age of 354 {plus minus} 49 Ma. This age is in agreement with the accepted age of the Bakken Shale ({approx}360 Ma). The initial {sup 187}Os/{sup 186}Os ratio of the isochron is 6.2 {plus minus} 3.3. This value is indistinguishable from the {sup 187}Os/{sup 186}Os ratios observed in modern Black Sea sediments. The concentration of common Os in Bakken Shale samples is strongly correlated with total nitrogen, indicating that a large fraction of the Os in these samples is associated with a hydrogenous component, which overwhelms any Os supplied to the sediment in association with detrital material or cosmic dust. The dominance of the hydrogenous component imparts a relatively homogeneous initial {sup 187}Os/{sup 186}Os ratio to the sediment at the time of deposition. The degree of scatter about the isochron exceeds the degree of scatter expected from either analytical error or from the estimated degree of initial isotopic heterogeneity. The pattern of scatter is consistent with postdepositional mobilization of Re and/or Os on a small spatial scale. The author suggest that this mobilization may be a consequence of petroleum formation and migration in the Bakken Shale.

    This report summarizes current research needs relating to oil shale utilization which might also provide new insight into the organic geochemistry of the Green River formation. There are two general topics which cross boundaries and are particularly worthy of emphasis. The first is a study of changes in the kerogen structure and biological markers with depth and location, and how these changes affect the pyrolysis products. This information would be particularly useful to the retort diagnostic methods. It might also lead to a better chemical reaction model of diagenesis and metagenesis. The second is a study of the heteroatom chemistry of the kerogen and how it relates to mineral matter and trace metals. This would be useful not only to present utilization methods, but also might suggest new nonthermal methods of organic materials recovery.

    Anisotropy analysis becomes an important step in processing and interpretation of seismic data. One of the most important things in anisotropy analysis is anisotropy parameter estimation which can be estimated using well data, core data or seismic data. In seismic data, anisotropy parameter calculation is generally based on velocity moveout analysis. However, the accuracy depends on data quality, available offset, and velocity moveout picking. Anisotropy estimation using seismic data is needed to obtain wide coverage of particular layer anisotropy. In anisotropic reservoir, analysis of anisotropy parameters also helps us to better understand the reservoir characteristics. Anisotropy parameters, especially ε, are related to rock property and lithology determination. Current research aims to estimate anisotropy parameter from seismic data and integrate well data with case study in potential shale gas reservoir. Due to complexity in organic-rich shale reservoir, extensive study from different disciplines is needed to understand the reservoir. Shale itself has intrinsic anisotropy caused by lamination of their formed minerals. In order to link rock physic with seismic response, it is necessary to build forward modeling in organic-rich shale. This paper focuses on studying relationship between reservoir properties such as clay content, porosity and total organic content with anisotropy. Organic content which defines prospectivity of shale gas can be considered as solid background or solid inclusion or both. From the forward modeling result, it is shown that organic matter presence increases anisotropy in shale. The relationships between total organic content and other seismic properties such as acoustic impedance and Vp/Vs are also presented.

    The Devonian-Mississippian black-shale sequence is one of the most prominent and well-known stratigraphic horizons in the Paleozoic of the United States, yet the paleontology and its paleoecologic and paleoenvironmental implications are poorly known. This is in larger part related to the scarcity of fossils preserved in the shale - in terms of both diversity and abundance. Nonetheless, that biota which is preserved is well-known and much described, but there is little synthesis of this data. The first step in such a synthesis is the compilation of an inclusive bibliography such as this one. This bibliography contains 1193 entries covering all the major works dealing with Devonian-Mississippian black-shale paleontology and paleoecology in North America. Articles dealing with areas of peripheral interest, such as paleogeography, paleoclimatology, ocean circulation and chemistry, and modern analogues, are also cited. In the index, the various genera, taxonomic groups, and other general topics are cross-referenced to the cited articles. It is hoped that this compilation will aid in the synthesis of paleontologic and paleoecologic data toward a better understanding of these unique rocks and their role as a source of energy.

    This study is an attempt to understand how native organics are distributed with respect to pore size to determine the relationship between hydrocarbon chemistry and pore structure in shales, as the location and accessibility of hydrocarbons is key to understanding and improving the extractability of hydrocarbons in hydraulic fracturing. Selected shale cores from the Eagle Ford and Marcellus formations were subjected to pyrolysis gas chromatography (GC), thermogravimetric analysis, and organic solvent extraction with the resulting effluent analyzed by GC-mass spectrometry (MS). Organics representing the oil and gas fraction (0.1 to 1 wt. %) were observed by GC-MS. For most ofmore » the samples, the amount of native organic extracted directly related to the percentage of clay in the shale. The porosity and pore size distribution (0.95 nm to 1.35 m) in the Eagle Ford and Marcellus shales was measured before and after solvent extraction using small angle neutron scattering (SANS). An unconventional method was used to quantify the background from incoherent scattering as the Porod transformation obscures the Bragg peak from the clay minerals. Furthermore, the change in porosity from SANS is indicative of the extraction or breakdown of higher molecular weight bitumen with high C/H ratios (asphaltenes and resins). This is mostly likely attributed to complete dissolution or migration of asphaltenes and resins. These longer carbon chain lengths, C30-C40, were observed by pyrolysis GC, but either were too heavy to be analyzed in the extracts by GC-MS or were not effectively leached into the organic solvents. Thus, experimental limitations meant that the amount of extractable material could not be directly correlated to the changes in porosity measured by SANS. But, the observable porosity generally increased with solvent extraction. A decrease in porosity after extraction as observed in a shale with high clay content and low maturity was attributed to swelling of pores

    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.

    Pores within organic matter (OM) are a significant contributor to the total pore system in gas shales. These pores contribute most of the storage capacity in gas shales. Here we present a novel approach to characterize the OM pore structure (including the porosity, specific surface area, pore size distribution, and water accessibility) in Marcellus shale. By using ultrasmall and small-angle neutron scattering, and by exploiting the contrast matching of the shale matrix with suitable mixtures of deuterated and protonated water, both total and water-accessible porosity were measured on centimeter-sized samples from two boreholes from the nanometer to micrometer scale withmore » good statistical coverage. Samples were also measured after combustion at 450 °C. Analysis of scattering data from these procedures allowed quantification of OM porosity and water accessibility. OM hosts 24–47% of the total porosity for both organic-rich and -poor samples. This porosity occupies as much as 29% of the OM volume. In contrast to the current paradigm in the literature that OM porosity is organophilic and therefore not likely to contain water, our results demonstrate that OM pores with widths >20 nm exhibit the characteristics of water accessibility. In conclusion, our approach reveals the complex structure and wetting behavior of the OM porosity at scales that are hard to interrogate using other techniques.« less

    This invention is a continuous retorting process for various high molecular weight organic materials, including oil shale, that yields an enhanced output of liquid product. The organic material, mineral matter, and an acidic catalyst, that appreciably adsorbs alkenes on surface sites at prescribed temperatures, are mixed and introduced into a pyrolyzer. A circulating stream of olefin enriched pyrolysis gas is continuously swept through the organic material and catalyst, whereupon, as the result of pyrolysis, the enhanced liquid product output is provided. Mixed spent organic material, mineral matter, and cool catalyst are continuously withdrawn from the pyrolyzer. Combustion of the spent organic material and mineral matter serves to reheat the catalyst. Olefin depleted pyrolysis gas, from the pyrolyzer, is enriched in olefins and recycled into the pyrolyzer. The reheated acidic catalyst is separated from the mineral matter and again mixed with fresh organic material, to maintain the continuously cyclic process.

    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.

    Simulations of methane production and supercritical carbon dioxide injection were developed that consider competitive adsorption of CH4 and CO2 on both organic matter and montmorillonite. The results were used to assess the potential for storage of CO2 in a hydraulically fractured shale gas reservoir and for enhanced recovery of CH4. Assuming equal volume fractions of organic matter and montmorillonite, amounts of CO2 adsorbed on both materials were comparable, while methane desorption was from clays was two times greater than desorption from organic material. The most successful strategy considered CO2 injection from a separate well and enhanced methane recovery by 73%, while storing 240 kmt of CO2.

    A series of hydrous pyrolysis experiments were conducted at temperatures ranging from 125 to 360C at 350 bars pressure to examine variations in sulfur speciation during thermal maturation of Monterey shale. The total sediment, kerogen and bitumen from each experiment in addition to unheated representatives were analyzed via x-ray absorption spectroscopy, pyrolysis-gas chromatography, {sup 30}NMR spectrometry, elemental analysis, thin-layer chromatography and reflected light microscopy. Based on these measurements, it was possible to recognize three distinct temperature regimes, within which the type and amount of sulfur in the analyzed fractions underwent transformations: (1) between 150 and 225C significant proportion of kerogen-bound sulfur is lost probably due to the collapse of polysulfide bridges; (2) between 225 and 275C, cleavage of -S-S- and -S-C- linkages within the kerogen is believed to occur, resulting in substantial production of polar sulfur-rich bitumen; (3) above 275C total bitumen yields as well as the proportion of bitumen sulfur decrease, while C-C bond scission leads to increased yields of saturated and aromatic hydrocarbons. The results from this study clearly and quantitatively establish a link between organically-bound sulfur, and more specifically, organic polysulfides, and the low-temperature evolution of soluble petroleum-like products (bitumen) from sulfur-rich source rocks.

    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.

    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.

    The upper Devonian Antrim Shale is a self-sourced, fractured gas reservoir that has been the target of intensive exploitation around the margin of the Michigan Basin. Significant amounts of water are commonly produced with methane in regions adjacent to subcrop of the Antrim Shale. Chemical and isotopic properties measured in the formation waters show significant regional variations and probably delineate zones of increased flow controlled by the fracture network within the Antrim Shale. The isotopic composition of Antrim methane ({gamma}{sup 13}C = -49 to -59{per_thousand}) was used to suggest that the gas is of thermtogenic origin. However, the highly {sup 13}C-enriched carbon of co-produced CO{sub 2} gas ({gamma}{sup 13}C {approx} +22{per_thousand}) and DIC in associated Antrim brines ({gamma}{sup 13}C = +19 to +31{per_thousand}) are consistent with bacterially mediated fractionation. Deuterium values in the methane ({gamma}D = -200 to -260{per_thousand}) also support a bacterial origin for methane. Preliminary correlation of deuterium in methane with that of the Antrim waters implies that methane is being generated via CO{sub 2} reduction within the reservoir.

    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.

    This report is a preliminary overview of oil-shale potential in Missouri. Two types of oil shales occur in Missouri: (1) the platform marine type, represented by the Devonian Chattanooga Shale, and (2) black shales in Pennsylvanian cyclothems, many of which overlie currently mined coal beds. The Chattanooga Shale contains black, fissile, carbonaceous shales and reaches a thickness of around 70 ft in southwestern Missouri. Oil-yield data from Missouri are not available, but based on yields from other states, the Chattanooga of southwest Missouri is estimated to contain between 2.6 and 15.8 billion barrels of oil. Preliminary estimates of the black, hard, fissile, carbonaceous Pennsylvanian shales indicate they contain between 100 and 200 billion barrels of shale oil. Many of these units directly overlie currently mined coal seams and could be recovered with the coal, but they are now discarded as overburden. These shales also contain significant amounts of phosphates and uranium. Other Paleozoic units with limited oil-shale potential are the Ordovician Decorah and Maquoketa Formations and the Upper Devonian Grassy Creek Shale. Ambitious research programs are needed to evaluate Missouri oil-shale resources. Further investigations should include economic and technological studies and the drilling, mapping, and sampling of potential oil-shale units. Shrinking supplies of crude oil make such studies desirable.

    In this paper we present results on characterization of filter-collected redwood (Sequoia sempevirens)-needle and eucalyptus smoke particles by thermal, optical, and solvent extraction methods. Our results demonstrate that organic and black carbon concentrations determined by thermal and optical methods are not only method dependent, but also critically influenced by the overall chemical composition of the samples. These conclusions are supported by the following: (1) the organic fraction of biomass smoke particles analyzed includes a component, ranging in concentration from about 6-20% of total carbon or from 16-30% of organic carbon, that is relatively non-volatile and has a combustion temperature close to that of black carbon; (2) presence of K or Na in biomass smoke samples lowers the combustion temperatures of this organic component and of black carbon, making their combustion properties indistinguishable; (3) about 20% of total organic material is nonvolatile when heated to 550{degrees}C in an inert atmosphere. Consequently, thermal methods that rely on a specific temperature to separate organic from black carbon may either underestimate or overestimate the black and organic carbon concentrations, depending on the amounts of Na and K and on the composition and concentration of organic material present in a sample. These analytical uncertainties and, under some conditions, absorption by organic material may contribute to the variability of empirically derived proportionality between light transmission through filter deposits and black carbon concentrations.

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

    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

    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.

    The Middle and Upper Ordovician Utica Shale is an important petroleum source rock in the central Appalachian basin. We analyzed a continuous core of the Utica Shale between 5630 and 5749 ft in the Redstone No. 3 Barth well, Coshocton County, Ohio, to geochemically characterize the Utica in a region of relatively low thermal maturity. Rock-Eval analyses of ten black shale samples, yielding average TOC = 3.1%, Tmax = 440{degrees}C, and Pl = 0.27, indicate that the Utica Shale in Coshocton County is a very good petroleum source rock that has reached the beginning to middle part of the oil-generation stage. Conodont alteration index (CAl) values of 1 to 1.5 from conodonts in thin calcareous beds in the Utica Shale support the Rock-Eval data. Average Hl = 174 mgHC/g C{sub org} and OL = 76 mgCO{sub 2}/g C{sub org} indicate a predominance of Type II organic matter in the Utica. Bitumen was extracted from four Utica shale samples (5,200 to 6,000 ppm) and analyzed by gas chromoatography (GC) and GC-mass spectrometry. Gas chromatograms show a slight-odd-predominance of the n-C{sub 11} to n-C{sub 17} fraction, a broad spectrum of n-alkanes that range from n-C{sub 7} to n-C{sub 33}, and abundant pristane and phytane. Mass fragmentograms of biomarker compounds reveal abundant terpane (191 m/z) and sterane (217 m/z) compounds and few pentacyclic (191 m/z) compounds. Except for the low concentration of pentacyclics, the bitumen extracts are very similar geochemically to oils produced from Cambrian and Lower Ordovician reservoirs in eastern and central Ohio. Maturation kinetics models indicate that the Utica Shale in the core reached the oil-generation stage during Pennsylvanian time.

    This invention relates to processing shale oil and in particular to processing shale oil to reduce the arsenic content. Specifically, the invention relates to treating shale oil by a combination of processes - coking and water washing. Many shale oils produced by conventional retorting processes contain inorganic materials, such as arsenic, which interfere with subsequent refining or catalytic hydroprocessing operations. Examples of these hydroprocessing operations are hydrogenation, denitrogenation, and desulfurization. From an environmental standpoint, removal of such contaminants may be desirable even if the shale oil is to be used directly as a fuel. Hence, it is desirable that contaminants such as arsenic be removed, or reduced to low levels, prior to further processing of the shale oil or prior to its use as a fuel.

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

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

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

    The Noto and Streppenosa formations of the Ragusa basin (southeastern Sicily) are considered the main source rocks for oil in this area. They display various styles of sedimentation in a generally carbonate context. The organic matter is basically of marine planktonic origin but with some variations, especially in terms of O/C ratio and kinetic behavior. Three main styles of sedimentation occurred within these formations: (1) laminates in a dominantly carbonate rock with thin recurrent interlayers of black shales; (2) alternating layers of marls and limestones, both containing interlayers of black shales and with occasional laminations in the limestones; and (3) silty shales, more or less rich in carbonates (30-70%). The highest petroleum potentials are neither strictly associated with the algal-sedimentary laminites nor with the basinal silty facies but with the black shales interbedded in the different facies or abruptly overlying limestones. In these black shales, oxygen-poor kerogens are dominant. Limestones of the alternated layers are generally organic lean (TOC < 1%), and oxygen-rich kerogens are dominant. The transition from one type of kerogen to the other occurs in the marly layers of the sequence. A tentative integration of both sedimentological and geochemical results is proposed, at the scale of the core, to interpret the respective influence of the depositional pattern and the diagenetic conditions on the content and nature of the kerogen in the source rocks.

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

    The production of natural gas has become more and more important in the United States because of the development of hydraulic fracturing techniques, which significantly increase the permeability and fracture network of black shales. The pore structure of shale is a controlling factor for hydrocarbon storage and gas migration. In this work, we investigated the porosity of the Union Springs (Shamokin) Member of the Marcellus Formation from a core drilled in Centre County, PA, USA, using ultrasmall-angle neutron scattering (USANS), small-angle neutron scattering (SANS), focused ion beam scanning electron microscopy (FIB-SEM), and nitrogen gas adsorption. The scattering of neutrons by Marcellus shale depends on the sample orientation: for thin sections cut in the plane of bedding, the scattering pattern is isotropic, while for thin sections cut perpendicular to the bedding, the scattering pattern is anisotropic. The FIB-SEM observations allow attribution of the anisotropic scattering patterns to elongated pores predominantly associated with clay. The apparent porosities calculated from scattering data from the bedding plane sections are lower than those calculated from sections cut perpendicular to the bedding. A preliminary method for estimating the total porosity from the measurements made on the two orientations is presented. This method is in good agreement with nitrogen adsorption for both porosity and specific surface area measurements. Neutron scattering combined with FIB-SEM reveals that the dominant nanosized pores in organic-poor, clay-rich shale samples are water-accessible sheetlike pores within clay aggregates. In contrast, bubble-like organophilic pores in kerogen dominate organic-rich samples. Lastly, developing a better understanding of the distribution of the water-accessible pores will promote more accurate models of water–mineral interactions during hydrofracturing.

    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.

    Reserves, characteristics, energetics, chemistry, and technology of Israeli oil shales are described. Oil shale is the only source of energy and the only organic natural resource in Israel. Its reserves of about 12 billion tons will be enough to meet Israel`s requirements for about 80 years. The heating value of the oil shale is 1,150 kcal/kg, oil yield is 6%, and sulfur content of the oil is 5--7%. A method of oil shale processing, providing exhaustive utilization of its energy and chemical potential, developed in the Technion, is described. The principal feature of the method is a two-stage pyrolysis of the oil shale. As a result, gas and aromatic liquids are obtained. The gas may be used for energy production in a high-efficiency power unit, or as a source for chemical synthesis. The liquid products can be an excellent source for production of chemicals.

    1995-10-01

    Extraction of the bitumen fraction of El-Lajjun oil shale was carried out using 17 different solvents, pure and combined. Out of all the solvents used, toluene and chlorform were found to be the most efficient for extraction of the bitumen to perform the major part of the experiments. This selectivity was based on the quality and quantity of the yield and on the quantity of solvent recovered. Extraction was carried out using a Soxhlet extractor. For complete recovery of solvent the extract phase was subjected to two stages of distillation, simple distillation followed by fractional distillation, where different cuts of oil were obtained. It was found that an optimum shale size of 1.0 mm offered better solvent recovery. One hour was the optimum time needed for complete extraction. The yield of oil was determined from the material balance gained from fractional distillation after testing for the existence of any traces of solvent trapped in the different cuts by using a gas chromotography technique. When chloroform was used, it was found that the average amount of bitumen extracted was 0.037 g/g of shale, which corresponds to 98% of the actual bitumen trapped in the oil shale (by assuming the bitumen represents 15% of the organic matter) and 84.1% of solvent recovered. When toluene was used, it was found that the average amount of oil extracted was 0.0293 g/g/ of shale, which corresponds to 78% of the actual bitumen trapped in the oil shale (by assuming bitumen represents 15% of the organic matter) and 89.9% of solvent for extraction with toluene.

    The purpose of the research project was to investigate the feasibility of the chemically assisted in situ retort method for recovering shale oil from Colorado oil shale. The chemically assisted in situ procedure uses hydrogen chloride (HCl), steam (H{sub 2}O), and carbon dioxide (CO{sub 2}) at moderate pressure to recovery shale oil from Colorado oil shale at temperatures substantially lower than those required for the thermal decomposition of kerogen. The process had been previously examined under static, reaction-equilibrium conditions, and had been shown to achieve significant shale oil recoveries from powdered oil shale. The purpose of this research project was to determine if these results were applicable to a dynamic experiment, and achieve penetration into and recovery of shale oil from solid oil shale. Much was learned about how to perform these experiments. Corrosion, chemical stability, and temperature stability problems were discovered and overcome. Engineering and design problems were discovered and overcome. High recovery (90% of estimated Fischer Assay) was observed in one experiment. Significant recovery (30% of estimated Fischer Assay) was also observed in another experiment. Minor amounts of freed organics were observed in two more experiments. Penetration and breakthrough of solid cores was observed in six experiments.

  20. History of western oil shale

    SciTech Connect (OSTI)

    Russell, P.L.

    1980-01-01

    The history of oil shale in the United States since the early 1900's is detailed. Research on western oil shale probably began with the work of Robert Catlin in 1915. During the next 15 years there was considerable interest in the oil shales, and oil shale claims were located, and a few recovery plants were erected in Colorado, Nevada, Utah, Wyoming, and Montana. Little shale soil was produced, however, and the major oil companies showed little interest in producing shale oil. The early boom in shale oil saw less than 15 plants produce a total of less than 15,000 barrels of shale oil, all but about 500 barrels of which was produced by the Catlin Operation in Nevada and by the US Bureau of Mines Rulison, Colorado operation. Between 1930 and 1944 plentiful petroleum supplies at reasonable prices prevent any significant interest in shale oil, but oil shortages during World War II caused a resurgence of interest in oil shale. Between 1940 and 1969, the first large-scale mining and retorting operations in soil shale, and the first attempts at true in situ recovery of shale oil began. Only 75,000 barrels of shale oil were produced, but major advancements were made in developing mine designs and technology, and in retort design and technology. The oil embargo of 1973 together with a new offering of oil shale leases by the Government in 1974 resulted in the most concentrated efforts for shale oil production to date. These efforts and the future prospects for shale oil as an energy source in the US are discussed.

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

    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.

  10. Fractured shale reservoirs: Towards a realistic model

    SciTech Connect (OSTI)

    Hamilton-Smith, T.

    1996-09-01

    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).

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

  15. Star formation and cosmic massive black hole formation, a universal process organized by angular momenta

    2004-01-01

    It is suggested that star formation is organized following the same principles as we have applied in a recent explanation of galaxy and massive black hole formation. In this scenario angular momentum is randomly distributed by tidal torquing among condensations, Lyman-{alpha} clouds or cores for star formation during the initial non-linear phase of collapse. This angular momentum is characterized by the parameter, {lambda}, the ratio of the angular momentum of the cloud to that of a Keplerian orbit with the same central mass and radius. This parameter is calculated in very many simulations of structure formation of the universe as well as core formation and appears to be universal and independent of any scale. The specific angular momentum during the collapse of every cloud is locally conserved and universally produces a near flat rotation curve M{sub black hole, 10{sup 8} M{sub o}, ({sup -}10{sup -3} of the galactic disk mass) or 1 M{sub o} ({sup -}0.03 of the core or of the protostellar disk mass). The inviscid collapse of a protosteller core with the same average {lambda} = 0.05 leads to the formation of a flat rotation curve (protostellar) disk of mass M{sub dsk} {sup -}30 M{sub o} of radius R{sub dsk} {approx_equal} 1100 AU or 5.4 x 10{sup -3} pc.

    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.

  17. Did Devonian shale wells drilled during the 1980`s and early 1990`s in West Virginia measure up to expectations?

    In the mid-1980`s, a model of future Devonian shale drilling and production was prepared for the Gas Research Institute (GRI). In late 1995, the West Virginia Geological and Economic Survey (WVGES) was contracted by GRI to evaluate actual drilling and production in the 1980`s and early 1990`s and compare these data to the predictions made in the existing model. Drilling activity data were compiled for the years 1979-1993 for all wells drilled, and for all Devonian shale wells drilled. Monthly and annual production data were summarized for both categories. The Devonian shale wells were subdivided into two subsets: (1) the western black shales trend and (2) the eastern black and gray shales and siltstones trend, according to the play definitions used in the {open_quotes}Atlas of Major Appalachian Gas Reservoirs{close_quotes}. Devonian shale wells were subdivided into vintages by completion year. Finally, each Devonian shale well was assigned to a 30 minute geographic grid or {open_quotes}cell{close_quotes} and production data were compiled and compared between cells. Analysis of the data led to the following conclusions: fewer shale wells were being drilled in the early 1990s, but these wells had better recoveries than the wells drilled in the 1980s. Some grid cells showed higher recoveries for the black and gray shales and siltstones play than in cells with black shale reservoirs alone. These higher recoveries perhaps can be attributed to the common practice of completing and producing shallower zones (i.e. Mississippian sandstones) in addition to the Devonian shales.

    1994-06-01

    One area where water-based muds need improved performance is in shale inhibition. However, before existing mud systems can be improved, the mechanisms by which water invades shales and how present-day inhibitive additives operate must be fully understood. An experimental technique has been developed that uses radioactive tracers to monitor the progress of water and selected dissolved ions through a shale core plug. By varying experimental parameters, such as water composition and applied pressure drop, the dominant mechanisms by which water is transported through shales have been identified. Under conditions of zero applied pressure, diffusion processes control water and ion movement through shales. Concentration gradients are the driving force for mass transfer of ionic species through shales. The authors observed no evidence to indicate that osmosis cause mass transfer of water. Applied pressure caused an increase in water and ion transport rates. Above a threshold pressure, water and dissolved ions travel at the same rate irrespective of the ion concentration.

    We present an emission inventory of primary black carbon (BC) and primary organic carbon (OC) aerosols from fossil fuel and biofuel combustion between 1850 and 2000. We reconstruct fossil fuel consumption and represent changes in technology on a national and sectoral basis. Our estimates rely on new estimates of biofuel consumption, and updated emission factors for old technologies. Emissions of black carbon increase almost linearly, totaling about 1000 Gg in 1850, 2200 Gg in 1900, 3000 Gg in 1950, and 4400 Gg in 2000. Primary organic carbon shows a similar pattern, with emissions of 4100 Gg, 5800 Gg, 6700 Gg, and 8700 Gg in 1850, 1900, 1950, and 2000, respectively. Biofuel is responsible for over half of BC emission until about 1890, and dominates energy-related primary OC emission throughout the entire period. Coal contributes the greatest fraction of BC emission between 1880 and 1975, and is overtaken by emissions from biofuel around 1975, and by diesel engines around 1990. Previous work suggests a rapid rise in BC emissions between 1950 and 2000. This work supports a more gradual increase between 1950 and 2000, similar to the increase between 1850 and 1925; implementation of clean technology is a primary reason.

    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.

    2014-12-02

    A method and apparatus are described for sequestering carbon dioxide underground by mineralizing the carbon dioxide with coinjected fluids and minerals remaining from the extraction shale oil. In one embodiment, the oil shale of an illite-rich oil shale is heated to pyrolyze the shale underground, and carbon dioxide is provided to the remaining depleted oil shale while at an elevated temperature. Conditions are sufficient to mineralize the carbon dioxide.

    Office of Energy Efficiency and Renewable Energy (EERE) (indexed site)

    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

    1995-06-15

    This year`s review on crude oil and shale oil has been prepared by classifying the references into the following main headings: Hydrocarbon Identification and Characterization, Trace Element Determination, Physical and Thermodynamic Properties, Viscosity, and Miscellaneous Topics. In the two-year review period, the references on shale oils were considerably less in number than those dealing with crude oils. Several new analytical methodologies and applications were reported for hydrocarbon characterization and trace element determination of crude oils and shale oils. Also included in this review are nine U.S., Canadian British and European patents. 12 refs.

  12. Modeling overpressures in sedimentary basins: Consequences for permeability and rheology of shales, and petroleum expulsion efficiency

    SciTech Connect (OSTI)

    Burrus, J.; Schneider, F.; Wolf, S. )

    1994-07-01

    The prediction of overpressures using Institut Francais du Petrole's 2-D numerical model TEMISPACK is applied to several provinces of the world. In the Paris basin, France, normally pressured Liassic shales are shown to have permeabilities around a microdarcy, independently confirmed by laboratory measurements. In contrast, in the Norway section of the North Sea, Williston Basin, Canada, Gulf Coast, and in the Mahakam delta, observed overpressures of 10-50 MPa are consistently modeled with shale permeabilities around 1-10 nanodarcys. This theoretical value fits well with the lowest permeability measured in compacted shales. For these basins, compaction disequilibrium was found to explain most (>85%) of the overpressures. The only exception was the Williston basin in which overpressures observed in the organic-rich Bakken shales are entirely due to hydrocarbon generation. In Mahakam delta, the rheology of shales is nonlinear, i.e., the strength of shales increases rapidly with death. Consequently, shale compaction cannot be described by the linear behavior often assumed in hydrology. In the absence of fault barriers, numerical simulations and geological evidence suggest that overpressured source rocks have low or very low expulsion efficiency, irrespective of their organic content. However, shales with a permeability on the order of a microdarcy do not hinder petroleum migration.

    1995-02-27

    The New Albany shale of southwestern Indiana is a worthwhile exploration and exploitation objective. The technical ability to enhance natural fractures is available, the drilling depths are shallow, long term gas reserves are attractive, markets are available, drilling costs are reasonable, risks are very low, multiple drilling objectives are available, and the return on investment is good. Indiana Geological Survey records are well organized, accessible, and easy to use. The paper describes the New Albany shale play, play size, early exploration, geologic setting, completion techniques, and locating prime areas.

    SciTech Connect (OSTI)

    1996-01-01

    This workshop is intended to provide an overview of the organic lithofacies, organic carbon content, thermal maturity, and gas potential of the Devonian and Mississippian New Albany Shale in the Illinois Basin. In addition, the reservoir characteristics and completion technology for productive organic-rich Devonian shales in the Michigan and Appalachian Basins are also reviewed. Emphasis is being placed on how proven technologies together with appropriate geologic and geochemical information can be used to explore for gas in the New Albany Shale.

  15. A feasibility study of oil shale fired pulse combustors with applications to oil shale retorting. Final report

    SciTech Connect (OSTI)

    Morris, G.J.; Johnson, E.K.; Zhang, G.Q.; Roach, R.A.

    1992-07-01

    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.

    Development of in situ electromagnetic (EM) retorting technologies and design of specific EM well logging tools requires an understanding of various process parameters (applied frequency, mineral phases present, water content, organic content and temperature) on oil shale dielectric properties. In this literature review on oil shale dielectric properties, we found that at low temperatures (<200 C) and constant oil shale grade, both the relative dielectric constant (?') and imaginary permittivity (?'') decrease with increased frequency and remain constant at higher frequencies. At low temperature and constant frequency, ?' decreases or remains constant with oil shale grade, while ?'' increases or shows no trend with oil shale grade. At higher temperatures (>200 C) and constant frequency, epsilon' generally increases with temperature regardless of grade while ?'' fluctuates. At these temperatures, maximum values for both ?' and ?'' differ based upon oil shale grade. Formation fluids, mineral-bound water, and oil shale varve geometry also affect measured dielectric properties. This review presents and synthesizes prior work on the influence of applied frequency, oil shale grade, water, and temperature on the dielectric properties of oil shales that can aid in the future development of frequency- and temperature-specific in situ retorting technologies and oil shale grade assay tools.

  18. Characterization of raw and burnt oil shale from Dotternhausen: Petrographical and mineralogical evolution with temperature

    SciTech Connect (OSTI)

    Thiéry, Vincent; Bourdot, Alexandra; Bulteel, David

    2015-08-15

    The Toarcian Posidonia shale from Dotternhausen, Germany, is quarried and burnt in a fluidized bed reactor to produce electricity. The combustion residue, namely burnt oil shale (BOS), is used in the adjacent cement work as an additive in blended cements. The starting material is a typical laminated oil shale with an organic matter content ranging from 6 to 18%. Mineral matter consists principally of quartz, feldspar, pyrite and clays. After calcination in the range, the resulting product, burnt oil shale, keeps the macroscopic layered texture however with different mineralogy (anhydrite, lime, iron oxides) and the formation of an amorphous phase. This one, studied under STEM, reveals a typical texture of incipient partial melting due to a long retention time (ca. 30 min) and quenching. An in-situ high temperature X-ray diffraction (HTXRD) allowed studying precisely the mineralogical changes associated with the temperature increase. - Highlights: • We present oil shale/burnt oil shale characterization. • The Posidonia Shale is burnt in a fluidized bed. • Mineralogical evolution with temperature is complex. • The burnt oil shale is used in composite cements.

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

    SciTech Connect (OSTI)

    Evans, R.A.

    1998-06-01

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

    1995-03-01

    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 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 (heating, mixing) conditions 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 and is reported on this quarter: (1) A software routine was written to eliminate intermittently inaccurate temperature readings. (2) We completed the quartz sand calibration runs, resolving calibration questions from the 3rd quarter. (3) We also made low temperature retorting runs to identify the need for certain kiln modifications and kiln modifications were completed. (4) Heat Conductance data on two Pyrolysis runs were completed on two samples of Occidental oil shale.

    The Knox Project objective is to evaluate the potential of formations within the Cambrian-Ordovician strata above the Mt. Simon Sandstone (St. Peter Sandstone and Potosi Dolomite) as potential targets for carbon dioxide (CO2) sequestration in the Illinois and Michigan Basins. The suitability of the St. Peter Sandstone and Potosi Dolomite to serve as reservoirs for CO2 sequestration is discussed in separate reports. In this report the data gathered from the Knox project, the Illinois Basin – Decatur Project (IBDP) and Illinois Industrial Carbon Capture and Sequestration project (IL-ICCS) are used to make some conclusions about the suitability of the Maquoketa shale as a confining layer for CO2 sequestration. These conclusions are then upscaled to basin-wide inferences based on regional knowledge. Data and interpretations (stratigraphic, petrophysical, fractures, geochemical, risk, seismic) applicable to the Maquoketa Shale from the above mentioned projects was inventoried and summarized. Based on the analysis of these data and interpretations, the Maquoketa Shale is considered to be an effective caprock for a CO2 injection project in either the Potosi Dolomite or St. Peter Sandstone because it has a suitable thickness (~200ft. ~61m), advantageous petrophysical properties (low effective porosity and low permeability), favorable geomechanical properties, an absence of observable fractures and is regionally extensive. Because it is unlikely that CO2 would migrate upward through the Maquoketa Shale, CO2, impact to above lying fresh water aquifers is unlikely. Furthermore, the observations indicate that CO2 injected into the St. Peter Sandstone or Potosi Dolomite may never even migrate up into the Maquoketa Shale at a high enough concentrations or pressure to threaten the integrity of the caprock. Site specific conclusions were reached by unifying the data and conclusions from the IBDP, ICCS and the Knox projects. In the Illinois Basin, as one looks further away from

  13. Regional geologic characteristics relevant to horizontal drilling, Woodford Shale, Anadarko basin, Oklahoma

    Horizontal drilling in the Late Devonian-Early Mississippian Bakken Formation of the Williston basin has spurred new interest in other black shales as primary hydrocarbon reservoirs. The Late Devonian-Early Mississippian Woodford Shale, which is similar in some respects to the Bakken Formation, is a major source of oil and gas in the Anadarko basin of Oklahoma and could prove to be a significant reservoir rock as well. The three regional geologic characteristics of the Woodford discussed here are of likely importance to horizontal drilling programs, although direct relations to drilling strategy cannot be developed until empirical data from horizontal tests become available. First, the Woodford Shale is composed of three distinct depositional units (the upper, middle, and lower informal members) with different physical and geochemical properties. Second, a paleotopographic high that was rising before and during Woodford deposition divided the Woodford Shale into northeast and southwest depocenters. Third, Woodford depositional patterns are overprinted by thermal-maturity trends shaped primarily by differential burial of the Woodford during Pennsylvanian and Permian time. The Woodford Shale northeast of the forebulge is generally immature to marginally mature, whereas its thermal maturity southwest of the forebulge ranges from mature to postmature with respect to oil generation. A formation resistivity of about 35 ohm-m approximates the updip limit of oil-saturated Woodford Shale from which free oil might be produced from fracture systems.

    2013-09-30

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

    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.

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

    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.

    The Petrobras oil shale retorting process, utilizes the particle range of +1/4 inch - 3 1/2 inches. The UPI plant in Sao Mateus do Sul has over 106,000 hours of operation, has processed over 6,200,000 metric tons of shale and has produced almost 3,000,000 barrels of shale oil. However, the nature of the raw oil shale is such that the amount of shale less than 1/4 inch that is mined and crushed and returned to the mine site is about 20 percent, thereby, increasing the cost of oil produced by a substantial number. Petrobras has investigated several systems to process the fines that are not handled by the 65 MTPH UPI plant and the 260 MTPH commercial plant. This paper provides an updated status of each of these processes in regard to the tests performed, potential contributions to an integrated use of the oil shale mine, and future considerations.

    When shale oils are applied at higher dose levels the standard observation of tumor production and latency are often obscured by a severe inflammatory response leading to epidermal degeneration. The two experiments reported here are still in progress, however the interim results are useful in assessing both the phlogistic and tumorigenic properties of three shale oils. Three shale oils were tested in these experiments. The first crude oil (OCSO No. 6) was produced in a modified in situ report at Occidental Oil Company's Logan Wash site near Debeque, Colorado. The second crude oil (PCSO II) was produced in the above ground Paraho vertical-kiln retort located at Anvil Points near Rifle, Colorado and the third oil was the hydrotreated daughter product of the Paraho crude (PCSO-UP). Experiment I was designed to determine the highest dose level at which tumor latency could be measured without interference from epidermal degeneration. Experiment II was designed to determine the effect of application frequency on both tumor response and inflammatory phenomena. Complete epidermal degeneration was used as the only measure of severe inflammation. Relative tumorigenicity was based on the number of tumor bearing mice without regard to multiple tumors on individual animals. In both experiments, tumor occurrence was confirmed one week after initial appearance. The sex-related difference in inflammatory response is striking and certanly has significance for experimental design. An increased phlogistic sensitivity expressed in male mice could affect the meaning of an experiment where only one sex was used.

    Upper Permian organic-rich lacustrine mudstones (oil shales) that crop out in the southern Junggar basin rank among the richest and thickest petroleum source rock intervals in the world, with maximum TOC values reaching 34% and Rock-Eval pyrolytic yields (S[sub 2]) up to 200 kg HC/t rock. Lacustrine sedimentary facies define an overall transgressive-regressive cycle of approximately 2000 m gross thickness, which includes approximately 800 m of source rocks averaging 4.1% TOC and 26.2 kg HC/t rock. Basinal facies comprise silicic, organic-rich, laminated lacustrine mudstones and interbedded siltstones; organic matter contained in the mudstones ranges in composition from type I to type III. Basinal facies were deposited in a deep, oxygen-deficient, stratified lake. Lake-margin facies consist of nonlaminated siliciclastic mudstones, rippled dolomitic silstones and sandstones, and minor limestones. Maximum TOC values are approximately 6%. Desiccation cracks are common in the marginal facies, but evaporite minerals are rare or absent. Biomarker correlation parameters measured from rock extracts exhibit significant stratigraphic variability, but strongly support the hypothesis that Upper Permian lacustrine oil shales charge the giant Karamay field in the northwestern Junggar basin. Karamay oils are characterized by high relative abundances of [beta]-carotane. This characteristic is restricted to desiccated facies in the outcrop sections, however. We therefore propose that an abundance of [beta]-carotane indicates elevated environmental salinities during deposition of the oil shales. 16 figs., 9 tabs.

    Information on the potential health effects of a developing oil shale industry can be derived from two major sources: (1) the historical experience in foreign countries that have had major industries; and (2) the health effects research that has been conducted in the US in recent years. The information presented here is divided into two major sections: one dealing with the experience in foreign countries and the second dealing with the more recent work associated with current oil shale development in the US. As a result of the study, several observations can be made: (1) most of the current and historical data from foreign countries relate to occupational hazards rather than to impacts on regional populations; (2) neither the historical evidence from other countries nor the results of current research have shown pulmonary neoplasia to be a major concern, however, certain types of exposure, particularly such mixed source exposures as dust/diesel or dust/organic-vapor have not been adequately studied and the lung cancer question is not closed; (3) the industry should be alert to the incidence of skin disease in the industrial setting, however, automated techniques, modern industrial hygiene practices and realistic personal hygiene should greatly reduce the hazards associated with skin contact; and (4) the entire question of regional water contamination and any resultant health hazard has not been adequately addressed. The industrial practice of hydrotreating the crude shale oil will diminish the carcinogenic hazard of the product, however, the quantitative reduction of biological activity is dependent on the degree of hydrotreatment. Both Soviet and American experimentalists have demonstrated a correlation betweed carcinogenicity/toxicity and retorting temperature; the higher temperatures producing the more carcinogenic or toxic products.

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

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

    SciTech Connect (OSTI)

    Ricketts, T.E.

    1984-04-24

    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.

  17. Additional potential for older, Antrim Shale wells

    SciTech Connect (OSTI)

    Frantz, J.H. Jr.; Hopkins, C.W.; Hill, D.G.

    1995-09-01

    The Gas Research Institute (GRI) has been performing evaluations to estimate the recompletion and restimulation potential in older, Antrim Shale wells. The recompletion potential is two-fold: (1) wells that can be deepened to the productive Norwood interval, and (2) wells with Upper Antrim potential. There are also numerous restimulation candidates due to sand flowback and/or other problems. The Antrim Shale is an organic-rich naturally fractured formation which produces both gas and water. Operators today typically complete the Lachine and Norwood intervals but many older wells were not drilled deep enough to encounter to Norwood. We performed an evaluation to determine the optimal deepening method using actual and simulated data. We estimate there are over 500 deepening candidates with total potential reserve additions of 50 Bscf. The Upper antrim formation can be added in approximately 1,500 existing wells throughout several counties. This interval is uphole from the Lachine and Norwood. In this phase of the project, we collected production and reservoir data from several Upper Antrim tests across the basin. We estimate the Upper Antrim could add total new reserves of 100 to 200 Bscf from al the recompletion candidates across the basin. In the restimulation evaluation, we developed a novel injection test unit to help operators identify the best restimulation candidates in a cost effective manner. The injection test determines if an effective hydraulic fracture is connected to the wellbore. Based on 60 test wells, we estimate the restimulations could add 50 to 200 Bscf of future reserves from the 500 to 1,000 candidate wells.

  18. Characterization of contaminants in oil shale residuals and the potential for their management to meet environmental quality standards. Final report

    Schmidt-Collerus, J.J.

    1984-02-01

    Some general aspects of various oil shale processes developed for scale-up to commercial size modular units are described. The overall magnitude of an envisioned commercial shale oil operation and the magnitude of resulting potentially polluting residues in particular solid residues from retorting oil shale and associated operations and wastewater from retort streams and other sources are considered. The potential problems ensuing from self-oxidation of stockpiles of oil shale and from residual carbonaceous retorted oil shale disposed above ground and/or from in situ retorting operations are examined. Some methods for managing self-heating processes are suggested. The most plausible method of avoiding potential self-heating for retorted oil shale is to oxidize as much as possible of the organic carbon present by utilizing a process that will produce low carbon or carbon-free retorted oil shale residues. In the case of unretorted oil shale, the dimensions and shapes of the stockpiles should be designed such that heat build-up is eliminated or kept to a minimum.

    This study demonstrates the significant lithologic variations that occur within the two shale samples from the Chittenango member of the Marcellus shale formation from western New York State in terms of mineralogical composition, type of lamination, pyrite occurrences and fossil content using thin section detailed description and field emission Scanning electron microscope (FESEM) with energy dispersive X-Ray Spectrum (EDX). This study is classified samples as laminated clayshale and fossiliferous carbonaceous shale. The most important detrital constituents of these shales are the clay mineral illite and chlorite, quartz, organic matter, carbonate mineral, and pyrite. The laminated clayshale has a lower amount of quartz and carbonate minerals than fossiliferous carbonaceous shale while it has a higher amount of clay minerals (chlorite and illite) and organic matter. FESEM analysis confirms the presence of chlorite and illite. The fossil content in the laminated clayshale is much lower than the fossiliferous carbonaceous shale. This can provide greater insights about variations in the depositional and environmental factors that influenced its deposition. This result can be compiled with the sufficient data to be helpful for designing the horizontal wells and placement of hydraulic fracturing in shale gas exploration and production.

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

    Antrim shale gas production grew from 0.4 Bcf in 1987 to 156 Bcf in 1994, causing record gas production in Michigan. Recent industry activity suggests the play will continue to expand. The GRI Hydrocarbon Model contains an Antrim resource base description that was developed in 1991. It was based on industry activity through 1990 and only covered the northern extent of the Antrim surrounding the current play. Significant technological improvements since then have resulted in projected near-term production lagging actual production by one to two years. Even so, the 1996 Edition of the GRI Baseline Projection predicts Antrim production will reach 1 Tcf by the year 2015. Given the 1996 projection results, a reassessment of the potential for producing gas from Antrim shale-type fractured reservoirs was initiated. The analysis identified general geological characteristics that appear to contribute to successful wells and extrapolated them to the rest of the Michigan Basin. Data used included production and well data through 1995, GRI-funded studies, and proprietary studies and data on the Antrim and deeper formations significant to gas origin and thermal maturity. Initial results suggest four {open_quotes}Resource Areas{close_quotes} based on comparison to the existing play using the following geological factors: (1) extent and thicknesses of the Lachine and Norwood organic shales; (2) regional structural expression of potential fracturing; (3) total depth relating to probability of open fractures; and (4) probability of biogenic gas contribution.

    2012-01-01

    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.

    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.

    Brazil, because of domestic crude oil shortage, took an interest in oil shale between 1940 and 1950. Petrobras, created in 1954, included in its charter the responsibility to develop a modern oil shale industry. An outgrowth has been the Petrosix process incorporated in a commercial unit in the State of Parana that has operated successfully more than 65,000 hours. Because of the maturity of the Petrosix process in this plant and the similarity of the Brazilian Irati oil shale to many other shales, interest has developed to apply the Petrosix process to producing shale oil and high BTU gas from these oil shales. A comparison of the characteristics has been developed between Irati and other oil shales. An evaluation of a commercial plant design has been completed for Irati, Kentucky, and Indiana oil shale projects. The technological and commercial aspects of producing shale oil using the Petrosix technology are discussed.

    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.

    1980-01-01

    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.

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

    Hydraulic fracturing of shale formations in the United States has led to a domestic energy boom. Currently, water is the only fracturing fluid regularly used in commercial shale oil and gas production. Industry and researchers are interested in non-aqueous working fluids due to their potential to increase production, reduce water requirements, and to minimize environmental impacts. Using a combination of new experimental and modeling data at multiple scales, we analyze the benefits and drawbacks of using CO? as a working fluid for shale gas production. We theorize and outline potential advantages of CO? including enhanced fracturing and fracture propagation, reduction of flow-blocking mechanisms, increased desorption of methane adsorbed in organic-rich parts of the shale, and a reduction or elimination of the deep re-injection of flow-back water that has been linked to induced seismicity and other environmental concerns. We also examine likely disadvantages including costs and safety issues associated with handling large volumes of supercritical CO?. The advantages could have a significant impact over time leading to substantially increased gas production. In addition, if CO? proves to be an effective fracturing fluid, then shale gas formations could become a major utilization option for carbon sequestration.

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.

    Oil shale deposits of the Green River Formation (GRF) in Northwestern Colorado, Southwestern Wyoming, and Northeastern Utah may become one of the first oil shale deposits to be developed in the U.S. because of their richness, accessibility, and extensive prior characterization. Oil shale is an organic-rich fine-grained sedimentary rock that contains significant amounts of kerogen from which liquid hydrocarbons can be produced. Water is needed to retort or extract oil shale at an approximate rate of three volumes of water for every volume of oil produced. Concerns have been raised over the demand and availability of water to produce oil shale, particularly in semiarid regions where water consumption must be limited and optimized to meet demands from other sectors. The economic benefit of oil shale development in this region may have tradeoffs within the local and regional environment. Due to these potential environmental impacts of oil shale development, water usage issues need to be further studied. A basin-wide baseline for oil shale and water resource data is the foundation of the study. This paper focuses on the design and construction of a centralized geospatial infrastructure for managing a large amount of oil shale and water resource related baseline data, and for setting up the frameworks for analytical and numerical models including but not limited to three-dimensional (3D) geologic, energy resource development systems, and surface water models. Such a centralized geospatial infrastructure made it possible to directly generate model inputs from the same database and to indirectly couple the different models through inputs/outputs. Thus ensures consistency of analyses conducted by researchers from different institutions, and help decision makers to balance water budget based on the spatial distribution of the oil shale and water resources, and the spatial variations of geologic, topographic, and hydrogeological Characterization of the basin.

    The fracture-permeability behavior of Utica shale, an important play for shale gas and oil, was investigated using a triaxial coreflood device and X-ray tomography in combination with finite-discrete element modeling (FDEM). Fractures generated in both compression and in a direct-shear configuration allowed permeability to be measured across the faces of cylindrical core. Shale with bedding planes perpendicular to direct-shear loading developed complex fracture networks and peak permeability of 30 mD that fell to 5 mD under hydrostatic conditions. Shale with bedding planes parallel to shear loading developed simple fractures with peak permeability as high as 900 mD. In addition to the large anisotropy in fracture permeability, the amount of deformation required to initiate fractures was greater for perpendicular layering (about 1% versus 0.4%), and in both cases activation of existing fractures are more likely sources of permeability in shale gas plays or damaged caprock in CO₂ sequestration because of the significant deformation required to form new fracture networks. FDEM numerical simulations were able to replicate the main features of the fracturing processes while showing the importance of fluid penetration into fractures as well as layering in determining fracture patterns.

    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.

  13. Assessment of Factors Influencing Effective CO{sub 2} Storage Capacity and Injectivity in Eastern Gas Shales

    SciTech Connect (OSTI)

    Godec, Michael

    2013-06-30

    Building upon advances in technology, production of natural gas from organic-rich shales is rapidly developing as a major hydrocarbon supply option in North America and around the world. The same technology advances that have facilitated this revolution - dense well spacing, horizontal drilling, and hydraulic fracturing - may help to facilitate enhanced gas recovery (EGR) and carbon dioxide (CO{sub 2}) storage in these formations. The potential storage of CO {sub 2} in shales is attracting increasing interest, especially in Appalachian Basin states that have extensive shale deposits, but limited CO{sub 2} storage capacity in conventional reservoirs. The goal of this cooperative research project was to build upon previous and on-going work to assess key factors that could influence effective EGR, CO{sub 2} storage capacity, and injectivity in selected Eastern gas shales, including the Devonian Marcellus Shale, the Devonian Ohio Shale, the Ordovician Utica and Point Pleasant shale and equivalent formations, and the late Devonian-age Antrim Shale. The project had the following objectives: (1) Analyze and synthesize geologic information and reservoir data through collaboration with selected State geological surveys, universities, and oil and gas operators; (2) improve reservoir models to perform reservoir simulations to better understand the shale characteristics that impact EGR, storage capacity and CO{sub 2} injectivity in the targeted shales; (3) Analyze results of a targeted, highly monitored, small-scale CO{sub 2} injection test and incorporate into ongoing characterization and simulation work; (4) Test and model a smart particle early warning concept that can potentially be used to inject water with uniquely labeled particles before the start of CO{sub 2} injection; (5) Identify and evaluate potential constraints to economic CO{sub 2} storage in gas shales, and propose development approaches that overcome these constraints; and (6) Complete new basin

    Hopkins, C.W.; Frantz, J.H. Jr.; Tatum, C.L.; Hill, D.G.

    This paper describes a simple method to identify, prioritize, and evaluate restimulation candidates in the Antrim Shale of the Michigan Basin. This work is being performed as part of an ongoing field-based Gas Research Institute (GRI) project investigating the Antrim Shale. There are between 500 and 1,000 Antrim Shale wells which could be candidates for restimulation due to previous screenouts and/or flowback problems, when sand consolidation material was not used. However, all of these wells might not benefit from restimulation, due to either poor reservoir quality or because the wells are already effectively stimulated. Based on historical results, the authors estimate the increase in reserves from restimulation could be between 50 and 400 MMscf per well, which could add 50 to 200 Bscf in future reserves from the 500--1,000 candidate wells.

  17. Shale Gas: Development Opportunities and Challenges

    SciTech Connect (OSTI)

    Zoback, Mark D.; Arent, Douglas J.

    2014-03-01

    The use of horizontal drilling and multistage hydraulic fracturing technologies has enabled the production of immense quantities of natural gas, to date principally in North America but increasingly in other countries around the world. The global availability of this resource creates both opportunities and challenges that need to be addressed in a timely and effective manner. There seems little question that rapid shale gas development, coupled with fuel switching from coal to natural gas for power generation, can have beneficial effects on air pollution, greenhouse gas emissions, and energy security in many countries. In this context, shale gas resources represent a critically important transition fuel on the path to a decarbonized energy future. For these benefits to be realized, however, it is imperative that shale gas resources be developed with effective environmental safeguards to reduce their impact on land use, water resources, air quality, and nearby communities.

  18. Oil shale retorting and combustion system

    DOE Patents [OSTI]

    Pitrolo, Augustine A.; Mei, Joseph S.; Shang, Jerry Y.

    1983-01-01

    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.

    1994-04-01

    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.

A mist of water droplets is generated and entrained in the combustion supporting gas flowing into the retort in order to distribute the liquid water droplets throughout the retort. The water droplets are vaporized in the retort in order to provide an efficient coolant for temperature control.

    1980-04-01

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

  11. Biomarker analysis of Upper Permian lacustrine oil shales, Junggar basin, NW China

    1990-05-01

    Upper Permian lacustrine oil shales containing up to 34% TOC (total organic carbon) underlie approximately 50,000 km{sup 2} of the Junggar basin in western China, and appear to be the principal source of oils in the giant Karamay field in the northwestern Junggar and in several recent discoveries in other areas of the basin. The siliceous oil shales were deposited in a sediment-starved foreland basin during a period of predominantly humid climate. Previous biomarker studies of crude oils from Karamay field have documented an abundance of {beta}-carotane (which in some cases dominates the aliphatic hydrocarbon distribution) and gammacerane, suggesting a source bed deposited under hypersaline conditions. However, relatively complete outcrop exposures of finely laminated oil shales in the southern Junggar conspicuously lack evaporites, extensive dessication horizons, or other sedimentological evidence of playa lake environments. Indeed, the aliphatic hydrocarbon distribution in bitumen extracts from southern Junggar oil shales appear characteristic of freshwater to brakish water deposition of organic matter in an anoxic lake. Normal alkanes show a slight odd-over-even preference with relatively low levels of the C{sub 22}, n-alkane, pristane/phytane ratios close to unity, low {beta}-carotane and gammacerane levels, and the absence of C{sub 34}-C{sub 35} hopanes. This apparent difference in source bed depositional environments may be due to tectonic partitioning between separate depocenters of the Late Permian Junggar basin. Alternatively, hypersaline oil shale facies may be limited to deeper basinal areas, whereas upslope southern Junggar sediments record highstands in lake level or influx of fresh water from the adjacent drainage areas.

    We propose the development of Nuclear Renewable Oil Shale Systems (NROSS) in northern Europe, China, and the western United States to provide large supplies of flexible, dispatchable, very-low-carbon electricity and fossil fuel production with reduced CO2 emissions. NROSS are a class of large hybrid energy systems in which base-load nuclear reactors provide the primary energy used to produce shale oil from kerogen deposits and simultaneously provide flexible, dispatchable, very-low-carbon electricity to the grid. Kerogen is solid organic matter trapped in sedimentary shale, and large reserves of this resource, called oil shale, are found in northern Europe, China, and the western United States. NROSS couples electricity generation and transportation fuel production in a single operation, reduces lifecycle carbon emissions from the fuel produced, improves revenue for the nuclear plant, and enables a major shift toward a very-low-carbon electricity grid. NROSS will require a significant development effort in the United States, where kerogen resources have never been developed on a large scale. In Europe, however, nuclear plants have been used for process heat delivery (district heating), and kerogen use is familiar in certain countries. Europe, China, and the United States all have the opportunity to use large scale NROSS development to enable major growth in renewable generation and either substantially reduce or eliminate their dependence on foreign fossil fuel supplies, accelerating their transitions to cleaner, more efficient, and more reliable energy systems.

    2011-06-03

    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.

    The mainstays of the economy in Morocco are still agriculture and phosphates; the latter represent 34% of world exports. Energy demand in 1985 will be probably 3 times that in 1975. Most of the oil, which covers 82% of its energy needs, must be imported. Other possible sources are the rich oil shale deposits and nuclear energy. Four nuclear plants with a total of 600 MW are projected, but shale oil still will play an important role. A contract for building a pilot plant has been met recently. The plant is to be located at Timahdit and cost $13 million, for which a loan from the World Bank has been requested. If successful in the pilot plant, the process will be used in full scale plants scheduled to produce 400,000 tons/yr of oil. Tosco also has a contract for a feasibility study.

    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.

    Some faults are fluid pathways but others are barriers. The latter type is well known in the oil and gas industry and attributed to granulation and shale smear. Fault zone granulation has been the focus of many recent studies, but shale smearing remains relatively obscure. We describe the geometry and structure of a normal fault with shale smear in a 1500m thick sedimentary sequence of Cambrian to Neogene age in a graben 10km west of Elat in southern Israel. The fault has a trace length of about 2km and is marked entirely by what remains of a formation made up of a 60m lower shale unit, 25m of middle carbonates, and 35m of upper shale. Both shale units have been stretched over a planar discontinuity defined by the footwall cut-off planes of the underlying sandstone and limestone units for 250m, the magnitude of the normal slip. Thus, the fault geometry and the position of the shale units reveal a smearing process by which the shale units reduce their thickness or nearly vanish by thinning perpendicular to the fault and stretching parallel to the fault. In a few exposures, the lower shale unit is reduced from 60m to a thickness less than 0.5m. The middle carbonates display boudinage and form discontinuous lenses along the fault. The impact of the intense continuous deformation, the discontinuous deformation by the faults, joints and veins of the shale and surrounding competent rocks, and mixing of the shale with adjacent permeable units, on the hydraulics of the fault zone and its sealing potential need to be carefully evaluated. This study improves the present knowledge about how fault zones may incorporate shales therein act as lateral seals for hydrocarbons, and when and how this sealing potential may be breached.

    The greatest single expense faced by oil companies involved in the exploration for crude oil is that of drilling wells. The most abundant rock drilled is shale. Some of these shales cause wellbore stability problems during the drilling process. These can range from slow rate of penetration and high torque up to stuck pipe and hole abandonment. The mechanical integrity of the shale must be known when the shalers are subjected to drilling fluids to develop an effective drilling plan.

    Rock-Eval (pyrolysis) studies of Ordovician Maquoketa Shale samples (cuttings and cores) from the shallow subsurface (500-800 ft deep) in western Illinois indicate that facies within the Maquoketa have potential as hydrocarbon source rocks. Dark, presumably organic-rich zones within the Maquoketa Shale were selected and analyzed for total organic carbon (TOC), Rock-Eval (pyrolysis), and bulk and clay mineralogy using x-ray diffraction. Preliminary results from six samples from Schuyler, McDonough, and Fulton Counties show TOC values ranging from 4.70% to as high as 12.90%. Rock-Eval parameters, measured by heating organic matter in an inert atmosphere, indicate source rock maturity and petroleum-generative potential. Screening studies, using the Rock-Eval process, describe very good source rock potential in facies of the Maquoketa Shale. Further studies at the Illinois State Geological Survey will expand on these preliminary results. This study complements a proposed exploration model in western Illinois and further suggests the possibility of source rocks on the flanks of the Illinois basin. Long-distance migration from more deeply buried effective source rocks in southern Illinois has been the traditional mechanism proposed for petroleum in basin-flank reservoirs. Localized source rocks can be an alternative to long-distance migration, and can expand the possibilities of basin-flank reservoirs, encouraging further exploration in these areas.

    In this study, hydraulic fracturing of shale formations in the United States has led to a domestic energy boom. Currently, water is the only fracturing fluid regularly used in commercial shale oil and gas production. Industry and researchers are interested in non-aqueous working fluids due to their potential to increase production, reduce water requirements, and to minimize environmental impacts. Using a combination of new experimental and modeling data at multiple scales, we analyze the benefits and drawbacks of using CO2 as a working fluid for shale gas production. We theorize and outline potential advantages of CO2 including enhanced fracturing and fracture propagation, reduction of flow-blocking mechanisms, increased desorption of methane adsorbed in organic-rich parts of the shale, and a reduction or elimination of the deep re-injection of flow-back water that has been linked to induced seismicity and other environmental concerns. We also examine likely disadvantages including costs and safety issues associated with handling large volumes of supercritical CO2. The advantages could have a significant impact over time leading to substantially increased gas production. In addition, if CO2 proves to be an effective fracturing fluid, then shale gas formations could become a major utilization option for carbon sequestration.

    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.

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

  2. Water-based glycol drilling muds: Shale inhibition mechanisms

    Aston, M.S.; Elliott, G.P.

    1994-12-31

    Water based glycol (polyol) muds are becoming increasingly popular, and are now replacing oil based muds in many drilling operations. Apart from exceptional shale inhibition, other benefits include environmental friendliness, ease of handling, robustness and good lubricity. This paper explores the mechanisms of shale stabilization by glycol muds. Experimental data show shale dispersion, swelling and hardness behaviors for a model reactive shale (London Clay). The data suggest the high level of inhibition obtained is mainly due to a shale hardening effect--the shale actually becomes harder than in its original state. Measurements with a range of salt types show that salt (eg KCl) plays a major role in the inhibiting mechanism. Adsorption measurements indicate that the glycol displaces water from the shale, resulting in a change in pore fluid composition. In effect, the glycol acts as a penetrating glue which, it is believed through hydrogen bonding effects, strengthens the shale. This mechanism contrasts with other water based mud additives (eg PHPA or polyamines) which form a protective or encapsulating layer on the surface of the shale.

    Crude shale oils produced by (a) Geokinetics, (b) Occidental, (c) Paraho, and (d) Tosco II processes have each been catalytically hydroprocessed to produce jet fuel fractions. The shale oil hydroprocessing was performed at low, medium and high hydroprocessing severities. Hydroprocessing severity was changed mainly by varying the temperature. Full boiling range (121-300/sup 0/C) jet fuel was produced from the hydroprocessed product of the raw oil distillates boiling below 343/sup 0/C. This paper describes the shale oil properties and hydroprocessing, gives the results of sulfur removal and hydrogenated shale oil distillation, and lists the physical and chemical properties of the jet fuels. 2 figures, 3 tables.

    1991-10-25

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

    Hydraulic fracturing technology (fracking), coupled with horizontal drilling, has facilitated exploitation of huge natural gas (gas) reserves in the Devonian-age Marcellus Shale Formation (Marcellus) of the Appalachian Basin. The most-efficient technique for stimulating Marcellus gas production involves hydraulic fracturing (injection of a water-based fluid and sand mixture) along a horizontal well bore to create a series of hydraulic fractures in the Marcellus. The hydraulic fractures free the shale-trapped gas, allowing it to flow to the well bore where it is conveyed to pipelines for transport and distribution. The hydraulic fracturing process has two significant effects on the local environment. First, water withdrawals from local sources compete with the water requirements of ecosystems, domestic and recreational users, and/or agricultural and industrial uses. Second, when the injection phase is over, 10 to 30% of the injected water returns to the surface. This water consists of flowback, which occurs between the completion of fracturing and gas production, and produced water, which occurs during gas production. Collectively referred to as returned frac water (RFW), it is highly saline with varying amounts of organic contamination. It can be disposed of, either by injection into an approved underground injection well, or treated to remove contaminants so that the water meets the requirements of either surface release or recycle use. Depending on the characteristics of the RFW and the availability of satisfactory disposal alternatives, disposal can impose serious costs to the operator. In any case, large quantities of water must be transported to and from well locations, contributing to wear and tear on local roadways that were not designed to handle the heavy loads and increased traffic. The search for a way to mitigate the situation and improve the overall efficiency of shale gas production suggested a treatment method that would allow RFW to be used as make

  19. Multi-temperature method for high-pressure sorption measurements on moist shales

    SciTech Connect (OSTI)

    2013-08-15

    A simple and effective experimental approach has been developed and tested to study the temperature dependence of high-pressure methane sorption in moist organic-rich shales. This method, denoted as multi-temperature (short multi-T) method, enables measuring multiple isotherms at varying temperatures in a single run. The measurement of individual sorption isotherms at different temperatures takes place in a closed system ensuring that the moisture content remains constant. The multi-T method was successfully tested for methane sorption on an organic-rich shale sample. Excess sorption isotherms for methane were measured at pressures of up to 25 MPa and at temperatures of 318.1 K, 338.1 K, and 348.1 K on dry and moisture-equilibrated samples. The measured isotherms were parameterized with a 3-parameter Langmuir-based excess sorption function, from which thermodynamic sorption parameters (enthalpy and entropy of adsorption) were obtained. Using these, we show that by taking explicitly into account water vapor as molecular species in the gas phase with temperature-dependent water vapor pressure during the experiment, more meaningful results are obtained with respect to thermodynamical considerations. The proposed method can be applied to any adsorbent system (coals, shales, industrial adsorbents) and any supercritical gas (e.g., CH{sub 4}, CO{sub 2}) and is particularly suitable for sorption measurements using the manometric (volumetric) method.

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

    Rutting of bituminous surfaces on the Jordanian highways is a recurring problem. Highway authorities are exploring the use of extracted shale oil and oil shale fillers, which are abundant in Jordan. The main objectives of this research are to investigate the rheological properties of shale oil binders (conventional binder with various percentages of shale oil), in comparison with a conventional binder, and to investigate the ability of mixes to resist deformation. The latter is done by considering three wearing course mixes containing three different samples of oil shale fillers--which contained three different oil percentages--together with a standard mixture containing limestone filler. The Marshall design method and the immersion wheel tracking machine were adopted. It was concluded that the shale oil binders displayed inconsistent physical properties and therefore should be treated before being used. The oil shale fillers have provided mixes with higher ability to resist deformation than the standard mix, as measured by the Marshall quotients and the wheel tracking machine. The higher the percentages of oil in the oil shale fillers, the lower the ability of the mixes to resist deformation.

    A method for rubblizing an oil shale deposit that has been formed in alternate horizontal layers of rich and lean shale, including the steps of driving a horizontal tunnel along the lower edge of a rich shale layer of the deposit, sublevel caving by fan drilling and blasting of both rich and lean overlying shale layers at the distal end of the tunnel to rubblize the layers, removing a substantial amount of the accessible rubblized rich shale to permit the overlying rubblized lean shale to drop to tunnel floor level to form a column of lean shale, performing additional sublevel caving of rich and lean shale towards the proximate end of the tunnel, removal of a substantial amount of the additionally rubblized rich shale to allow the overlying rubblized lean shale to drop to tunnel floor level to form another column of rubblized lean shale, similarly performing additional steps of sublevel caving and removal of rich rubble to form additional columns of lean shale rubble in the rich shale rubble in the tunnel, and driving additional horizontal tunnels in the deposit and similarly rubblizing the overlying layers of rich and lean shale and forming columns of rubblized lean shale in the rich, thereby forming an in situ oil shale retort having zones of lean shale that remain permeable to hot retorting fluids in the presence of high rubble pile pressures and high retorting temperatures.

    1983-12-01

    The upper and lower members of the Mississippian and Devonian Bakken Formation in the United States portion of the Williston basin are black shales that are extremely rich in organic matter and are the source of much of the oil found in the basin. Organic-carbon values are calculated from formationdensity logs using the equation: TOC = (154.497//rho/) -57.261, where TOC is organic-carbon content (wt. %) and /rho/ is formation density (g/cm/sup 3/). Test calculations comparing this equation to laboratory organic-carbon analyses from 39 wells in North Dakota show an average absolute difference of 1.1% in organic-carbon content. Organic-carbon content, calculated at 159 locations in North Dakota and 107 in Montana, averages 12.1% for the upper member of the Bakken Formation and 11.5% for the lower member. There is a regional depletion of organic carbon, paralleling present-day isotherms, that reflects the conversion of organic matter to oil and subsequent expulsion of the oil from the formation. The mass of organic carbon in the Bakken Formation is approximately evenly divided between the upper and lower members, and it totals about 126 X 10/sup 12/ kg in the study area, of which 102 X 10/sup 12/ kg are in the thermally mature region. The assumption that 167 mg HC/g TOC have migrated out of the mature Bakken shales leads to a tentative estimate that hydrocarbons equivalent to 132 billion bbl of 43/sup 0/ (API gravity) oil have been expelled from the United States portion of the upper and lower members of the Bakken Formation.

    Given the favorable production response that has been obtained from horizontal drilling in vertical- fractured reservoirs such as the Bakken shale and, more recently, the Austin chalk, industry interest in this technology has mushroomed in the U.S. Indeed, it is difficult to find a good-sized oil company these days that is not involved in a horizontal drilling project or is giving it serious consideration. In response to growing evidence of successful field applications, the realization is dawning on the investment community that horizontal drilling represents a significant technological development with positive implications for both the exploration and production business, and the oilfield services industry.

    Thirty-one industry people were contacted to provide input on oil shale in three subject areas. The first area of discussion dealt with industry's view of the shape of the future oil shale industry; the technology, the costs, the participants, the resources used, etc. It assessed the types and scale of the technologies that will form the industry, and how the US resource will be used. The second subject examined oil shale R D needs and priorities and potential new areas of research. The third area of discussion sought industry comments on what they felt should be the role of the DOE (and in a larger sense the US government) in fostering activities that will lead to a future commercial US oil shale shale industry.

    This paper discusses how preparations are being made for the construction and operation of a semi commercial plant to process Australian oil shale. This plant is primarily designed to demonstrate the technical feasibility of processing these shales at low cost. Nevertheless it is expected to generate modest profits even at this demonstration level. This will be the first step in a three staged development of one of the major Australian oil shale deposits which may ultimately provide nearly 10% of Australia's anticipated oil requirements by the end of the century. In turn this development should provide the basis for a full scale oil shale industry in Australia based upon the advantageously disposed oil shale deposits there. New sources of oil are becoming critical since Australian production is declining rapidly while consumption is accelerating.

    2009-01-01

    Oil shales are fine-grained sedimentary rocks that contain relatively large amounts of kerogen, which can be converted into liquid and gaseous hydrocarbons (petroleum liquids, natural gas liquids, and methane) by heating the rock, usually in the absence of oxygen, to 650 to 700 degrees Fahrenheit (in situ retorting) or 900 to 950 degrees Fahrenheit (surface retorting). (Oil shale is, strictly speaking, a misnomer in that the rock is not necessarily a shale and contains no crude oil.) The richest U.S. oil shale deposits are located in Northwest Colorado, Northeast Utah, and Southwest Wyoming. Currently, those deposits are the focus of petroleum industry research and potential future production. Among the three states, the richest oil shale deposits are on federal lands in northwest Colorado.

    Hydraulic fracturing of gas shale formations involves pumping a large volume of fracking fluid into a hydrocarbon reservoir to fracture the rock and thus increase its permeability. The majority of the fracking fluid introduced is never recovered and the fate of this lost fluid, often called “leak off,” has become the source of much debate. Information on the capillary pressure – saturation relationship for each wetting phase is needed to simulate leak off using numerical reservoir models. The petroleum industry commonly employs air – water capillary pressure – saturation curves to predict these relationships for mixed wet reservoirs. Traditional methodsmore » of measuring this curve are unsuitable for gas shales due to high capillary pressures associated with the small pores present. Still, a possible alternative method is the water activity meter which is used widely in the soil sciences for such measurements. However, its application to lithified material has been limited. Here, this study utilized a water activity meter to measure air – water capillary pressures (ranging from 1.3 to 219.6 MPa) at several water saturation levels in both the wetting and drying directions. Water contents were measured gravimetrically. Seven types of gas producing shale with different porosities (2.5–13.6%) and total organic carbon contents (0.4–13.5%) were investigated. Nonlinear regression was used to fit the resulting capillary pressure – water saturation data pairs for each shale type to the Brooks and Corey equation. Data for six of the seven shale types investigated were successfully fitted (median R2 = 0.93), indicating this may be a viable method for parameterizing capillary pressure – saturation relationships for inclusion in numerical reservoir models. As expected, the different shale types had statistically different Brooks and Corey parameters. However, there were no significant differences between the Brooks and Corey parameters for the wetting and

    1978-01-01

    In an in situ oil shale retorting process, plastic flow of hot rubblized oil shale is minimized by injecting carbon dioxide and water into spent shale above the retorting zone. These gases react chemically with the mineral constituents of the spent shale to form a cement-like material which binds the individual shale particles together and bonds the consolidated mass to the wall of the retort. This relieves the weight burden borne by the hot shale below the retorting zone and thereby minimizes plastic flow in the hot shale. At least a portion of the required carbon dioxide and water can be supplied by recycled product gases.

    Shale samples from four cores of the New Albany and Antrim Shales (Devonian) and from six cores of the Maquoketa Group (Ordovician), representing a broad geographic area of Indiana, have been analyzed for total organic carbon, total sulfur, pyrolysis yield (Rock-Eval), bitumen content, and illite crystallinity data. These data indicate that the New Albany, Antrim, and Maquoketa shales contain a sufficient quantity and quality of organic matter to be good petroleum source rocks. Bitumen ratios, Rock-Eval yields, gas chromatography of saturated hydrocarbons, and illite crystallinity data show that the Maquoketa shales have reached a higher level of thermal maturity than the New Albany and Antrim shales. The level of thermal maturity of the Maquoketa shales suggested a maximum burial depth considerably greater than the present depth.

    A comparative analysis of the amounts of 42 trace elements in coals, crude oils, and oil and black shales was performed. The degree of concentration of trace elements by caustobioliths and their ashes relative to their abundance in argillaceous rocks and the Earth's crust was calculated. Typomorphic trace elements were distinguished, of which many turned out to be common for the different kinds of caustobioliths in question. The trace elements were classified according to their concentration factors in different caustobioliths. The ash of crude oils is enriched in trace elements (Cs, V, Mo, Cu, Ag, Au, Zn, Hg, Se, Cr, Co, Ni, U) to the greatest extent (concentration factor above 3.5) and that of oil shales is enriched to the least extent (Re, Cs, Hg, Se). The ratios between typomorphic trace elements in general strongly differ from those in the Earth's crust and argillaceous rocks and are not identical in different caustobioliths. Quantitative parameters that make it possible to calculate a change in these ratios on passing from one caustobiolith type to another were proposed and the relative trace-element affinity of different caustobioliths was estimated.

    Methane from oil shale can potentially provide a significant contribution to natural gas industry, and it may be possible to increase and continue methane production by artificially enhancing methanogenic activity through the addition of various substrate and nutrient treatments. Western Research Institute in conjunction with Pick & Shovel Inc. and the U.S. Department of Energy conducted microcosm and scaled-up reactor studies to investigate the feasibility and optimization of biogenic methane production from oil shale. The microcosm study involving crushed oil shale showed the highest yield of methane was produced from oil shale pretreated with a basic solution and treated with nutrients. Incubation at 30 C, which is the estimated temperature in the subsurface where the oil shale originated, caused and increase in methane production. The methane production eventually decreased when pH of the system was above 9.00. In the scaled-up reactor study, pretreatment of the oil shale with a basic solution, nutrient enhancements, incubation at 30 C, and maintaining pH at circumneutral levels yielded the highest rate of biogenic methane production. From this study, the annual biogenic methane production rate was determined to be as high as 6042 cu. ft/ton oil shale.

    We have investigated the technical and economic barriers facing the introduction of an oil shale industry and we have chosen Hot-Recycled-Solid (HRS) oil shale retorting as the primary advanced technology of interest. We are investigating this approach through fundamental research, operation of a 4 tonne-per-day, HRS pilot plant and development of an Oil Shale Process (OSP) mathematical model. Over the last three years, from June 1991 to June 1993, we completed a series of runs (H10--H27) using the 4-TPD pilot plant to demonstrate the technical feasibility of the HRS process and answer key scale-up questions. With our CRADA partners, we seek to further develop the HRS technology, maintain and enhance the knowledge base gained over the past two decades through research and development by Government and industry and determine the follow on steps needed to advance the technology towards commercialization. The LLNL Hot-Recycled-Solid process has the potential to improve existing oil shale technology. It processes oil shale in minutes instead of hours, reducing plant size. It processes all oil shale, including fines rejected by other processes. It provides controls to optimize product quality for different applications. It co-generates electricity to maximize useful energy output. And, it produces negligible SO{sub 2} and NO{sub x} emissions, a non-hazardous waste shale and uses minimal water.

    The studied area is a lake basin located in Bolu basin in Turkey. In the basin, from Upper Cretaceous to Upper Miocene 3,000-m thickness sediments were deposited. Upper Miocene Himmetoglu formation consisted of sandstone, claystone, and marl. To the middle level of the formation are located coal, bituminous limestone, and bituminous shales. In the basin, there are two coal beds whose thicknesses range from 1 to 13 m. The coals are easily breakable and black in color. In the coal beds exists some bituminous limestone and bituminous shales, and their thicknesses are between 5 and 45 cm. The amount of organic matter of the bituminous rocks from the Upper Miocene Himmetoglu formation are between 6.83 and 56.34 wt%, and the amount of organic matter of the bituminous limestone from the formation are between 13.58 and 57.16 wt%. These values indicate that these rocks have very good source potential. According to hydrogen index (HI), S2/S3, HI-T{sub max}, and HI-OI (oxygen index) parameters, kerogen types of the bituminous rocks and coals belonging to Upper Miocene Himmetoglu formation are Type I, Type II, and Type III. In accordance with HI, S2/S3, HI-T{sub max}, and HI-OI parameters, the bituminous rocks and coals from the Upper Miocene Himmetoglu formation are mostly immature.

  11. Multi-scale and Integrated Characterization of the Marcellus Shale in the Appalachian Basin: From Microscopes to Mapping

    SciTech Connect (OSTI)

    Crandall, Dustin; Soeder, Daniel J; McDannell, Kalin T.; Mroz, Thomas

    2010-01-01

    Historic data from the Department of Energy Eastern Gas Shale Project (ESGP) were compiled to develop a database of geochemical analyses, well logs, lithological and natural fracture descriptions from oriented core, and reservoir parameters. The nine EGSP wells were located throughout the Appalachian Basin and intercepted the Marcellus Shale from depths of 750 meters (2500 ft) to 2500 meters (8200 ft). A primary goal of this research is to use these existing data to help construct a geologic framework model of the Marcellus Shale across the basin and link rock properties to gas productivity. In addition to the historic data, x-ray computerized tomography (CT) of entire cores with a voxel resolution of 240mm and optical microscopy to quantify mineral and organic volumes was performed. Porosity and permeability measurements in a high resolution, steady-state flow apparatus are also planned. Earth Vision software was utilized to display and perform volumetric calculations on individual wells, small areas with several horizontal wells, and on a regional basis. The results indicate that the lithologic character of the Marcellus Shale changes across the basin. Gas productivity appears to be influenced by the properties of the organic material and the mineral composition of the rock, local and regional structural features, the current state of in-situ stress, and lithologic controls on the geometry of induced fractures during stimulations. The recoverable gas volume from the Marcellus Shale is variable over the vertical stratigraphic section, as well as laterally across the basin. The results from this study are expected to help improve the assessment of the resource, and help optimize the recovery of natural gas.

  12. Hierarchical Pore Morphology of Cretaceous Shale: A Small-Angle Neutron Scattering and Ultrasmall-Angle Neutron Scattering Study

    Shale reservoirs are becoming an increasingly important source of oil and natural gas supply and a potential candidate for CO2 sequestration. Understanding the pore morphology in shale may provide clues to making gas extraction more efficient and cost-effective. The porosity of Cretaceous shale samples from Alberta, Canada, collected from different depths with varying mineralogical compositions, has been investigated by small- and ultrasmall-angle neutron scattering. Moreover these samples come from the Second White Specks and Belle Fourche formations, and their organic matter content ranges between 2 and 3%. The scattering length density of the shale specimens has been estimated using the chemical composition of the different mineral components. Scattering experiments reveal the presence of fractal and non-fractal pores. It has been shown that the porosity and specific surface area are dominated by the contribution from meso- and micropores. The fraction of closed porosity has been calculated by comparing the porosities estimated by He pycnometry and scattering techniques. There is no correlation between total porosity and mineral components, a strong correlation has been observed between closed porosity and major mineral components in the studied specimens.

  4. Barnett shale rising star in Fort Worth basin

    SciTech Connect (OSTI)

    Kuuskraa, V.A.; Koperna, G.; Schmoker, J.W.; Quinn, J.C.

    1998-05-25

    The Mississippian-age Barnett shale of the Fort Worth basin, North Texas, has emerged as a new and active natural gas play. Natural gas production from the Barnett shale at Newark East field in Denton and Wise counties, Texas, has reached 80 MMcfd from more than 300 wells. However, very little publicly available information exists on resource potential and actual well performance. The US Geological Survey 1995 National Assessment of US Oil and Gas Resources categorized the Mississippian Barnett shale play (play number 4503) as an unconventional gas play but did not quantitatively assess this resource. This article, which expands upon a recent USGS open-file resource assessment report, provides an updated look at the Barnett shale and sets forth a new quantitative assessment for the play.

    1996-12-31

    Prolific oil and gas production has been established from naturally fractured shale reservoirs. For example, in the last few years over 4 Tcf of gas reserves have been established within the self-sourcing Antrim Shale of the Michigan Basin. Historically, locating subsurface fracture systems essential for commercial production has proven elusive and costly. An integrated exploration approach utilizing available geologic, geophysical, and remote sensing data has successfully located naturally fractured zones within the Antrim Shale. It is believed that fracturing of the Antrim shale was a result of basement involved tectonic processes. Characteristic integrated stacked signatures of known fracture systems within the Antrim were built using gravity and magnetic data, structure maps, fracture identification logs, and Landsat imagery. Wireline fracture logs pinpointed the locations and geometries of subsurface fracture systems. Landsat imagery was interpreted to reveal surficial manifestations of subsurface structures.

    Shale gas resource potential in China is assessed to be large, and its development could have wide-ranging economic, environmental, and energy security implications. Although commercial scale shale gas development has not yet begun in China, it holds the potential to change the global energy landscape. Chinese decision-makers are wrestling with the challenges associated with bringing the potential to reality: geologic complexity; infrastructure and logistical difficulties; technological, institutional, social and market development issues; and environmental impacts, including greenhouse gas emissions, impacts on water availability and quality, and air pollution. This paper briefly examines the current situation and outlook for shale gas in China, and explores existing and potential avenues for international cooperation. We find that despite some barriers to large-scale development, Chinese shale gas production has the potential to grow rapidly over the medium-term.

    SciTech Connect (OSTI)

    1996-12-31

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