shale oil reserves

Adapting petrographic terms from coal terminology, Hutton developed a classification of oil shale based primarily on the origin of the organic matter. Organic matter in oil shale includes the remains of algae, spores, pollen, plant cuticle and corky fragments of herbaceous and woody plants, and other cellular remains of lacustrine, marine, and land plants. Shale gas has become the focus of global natural gas exploration, and shale oil plays an important role in unconventional oil and gas exploration. Most of the organic matter in oil shale is insoluble in ordinary organic solvents, whereas some is bitumen that is soluble in certain organic solvents. More information on Australia oil shale. The U.S. Securities and Exchange Commission requires oil companies to report with reasonable certainty the volume of reserves in wells that are profitable at … Most of these uses are still small or in experimental stages, but the economic potential is large. Shale has a shorter lead time between drilling and production relative to offshore exploration and other traditional oil projects, making it more responsive to oil price movements. The standardized Fischer assay method consists of heating a 100-gram sample crushed to -8 mesh (2.38-mm mesh) screen in a small aluminum retort to 500ºC at a rate of 12ºC per minute and held at that temperature for 40 minutes. This formation contains the largest oil shale deposits in the world. Marine oil shales are composed of lipid-rich organic matter derived from marine algae, acritarchs (unicellular organisms of questionable origin), and marine dinoflagellates. A new independent estimate of world oil reserves has been released by Rystad Energy, showing that the US now holds more recoverable oil reserves than both Saudi Arabia and Russia. The nation has a … However, looking at success in US lots of other countries have started to explore their shale reserves. Shale oil is a substitute for conventional crude oil. Vitrinite may be difficult to recognize in oil shale because it resembles other organic material of algal origin and may not have the same reflectance response as vitrinite, thereby leading to erroneous conclusions. Tectonic events and volcanism have altered some deposits. China, Russia, Syria, Thailand and Turkey, China, Russia, Syria, Thailand, and Turkey. Although shale oil in today's (2004) world market is not competitive with petroleum, natural gas, or coal, it is used in several countries that possess easily exploitable deposits of oil shale but lack other fossil fuel resources. It would be useful to develop a simple and reliable assay method for determining the energy potential of an oil shale that would include the total heat energy and the amounts of oil, water, combustible gases including hydrogen, and char in sample residue. Detailed north-south cross section showing environments of deposition, organic richness, and thermal maturities of lower Tertiary rocks in the Uinta Basin, Utah; 2014; SIM; 3304; Johnson, Ronald C. Histograms showing variations in oil yield, water yield, and specific gravity of oil from Fischer assay analyses of oil-shale drill cores and cuttings from the Piceance Basin, northwestern Colorado; 2014; OFR; 2014-1057; Dietrich, John D.; Brownfield, Michael E.; Johnson, Ronald C.; Mercier, Tracey J. 1, known as Elk Hills, was privatized, the first of a series of major organizational changes that leave only one of the original six Federal properties in the program. Since the oil-price bust of 2014, unpredictability has been the theme music of U.S. shale. This page accesses data for Oil Shale Assessments of PIceance, Uinta and Green River Basins. The availability and price of petroleum ultimately effect the viability of a large-scale oil-shale industry. S&P Global Platts forecasts a decline to 10m b/d by mid-2021. 6.2 Shale Oil Properties. … Geologists, petroleum companies and the federal government have known about these massive deposits for nearly a century. The Bakken Field in North Dakota and Montana is the largest producing shale oil reserve. In this regard, Colombia is preparing new tax incentives and is about to launch free-trade zones (see page 14). The U.S. Geological Survey (USGS) has compiled Part B of the Energy Map of Southwestern Wyoming for the Wyoming Landscape Conservation Initiative (WLCI). As supplies of petroleum diminish in future years and costs for petroleum increase, greater use of oil shale for the production of electric power, transportation fuels, petrochemicals, and other industrial products seems likely. More information on Israel and Jordan oil shale. This file is updated from the Piceance Basin Oil Shale Database with data for additional new drill holes. Other minor components in lamosite include vitrinite, inertinite, telalginite, and bitumen. Texas alone holds more than 60 billion barrels of shale oil according to this new data. In fact, special methods of retorting, such as the Hytort process, can increase oil yields of some oil shales by as much as three to four times the yield obtained by the Fischer assay method (Schora and others, 1983; Dyni and others, 1990). The thermal maturity of an oil shale refers to the degree to which the organic matter has been altered by geothermal heating. This is only slightly lower than the estimated 1.53 trillion barrels for the adjacent Piceance Basin, Colorado, to the east, which is thought to be the richest oil shale deposit in the world. The health impacts of the chemicals used in fracking and disposed of are not yet fully known. Here we will discuss mass-movement deposits in just the Piceance Basin part of Lake Uinta. Johnson, R.C., and Brownfield, M.E., 2015, Development, evolution, and destruction of the saline mineral area of Eocene Lake Uinta, Piceance Basin, western Colorado: U.S. Geological Survey Scientific Investigations Report 2013–5176, 76 p., 2 pl., http://dx.doi.org/10.3133/sir20135176. S ign U p F or our. In some oil shales, the organic matter is unstructured and is best described as amorphous (bituminite). Terrestrial oil shales include those composed of lipid-rich organic matter such as resin spores, waxy cuticles, and corky tissue of roots, and stems of vascular terrestrial plants commonly found in coal-forming swamps and bogs. Some organic matter retains enough biological structures so that specific types can be identified as to genus and even species. Oil shale, shale oil, and oil-bearing shale are three different substances. The recent successful development of a tight oil play in the Eocene-age informal Uteland Butte member of the lacustrine Green River Formation in the Uinta Basin, Utah, using modern horizontal drilling and hydraulic fracturing techniques has spurred a renewed interest in the tight oil potential of lacustrine rocks. Oil shale is a sedimentary rock. Today, few, if any deposits can be economically mined and processed for shale oil in competition with petroleum. For other oil shales, the reverse is true-silicates including quartz, feldspar, and clay minerals are dominant and carbonates are a minor component. Oil shale has received many different names over the years, such as cannel coal, boghead coal, alum shale, stellarite, albertite, kerosene shale, bituminite, gas coal, algal coal, wollongite, schistes bitumineux, torbanite, and kukersite. The average breakeven price of oil has fallen 4 percent (or $2 per barrel) over the past year, to $50 per barrel, according to the latest Dallas Fed Energy Survey. Bituminite, on the other hand, is largely amorphous, lacks recognizable biologic structures, and weakly fluoresces under blue light. Some oil shales may have a greater energy potential than that reported by the Fischer assay method depending on the components of the "gas plus loss.". US is making the most of Shale gas as they have lots of inhabited land. Deposits of shale oil / gas are found around the world. The well confirmed the existence of substantial reserves of shale gas in the Ahnet Basin, located in In Salah, 650 km northwest of Tamanrasset. Photo of abandoned oil shale mine at Anvil Points, Green River Formation, near Rifle Colorado, (Credit: Ronald C. Johnson, USGS - Central Energy Resources Science Center. Oil shales range widely in organic content and oil yield. Early attempts to determine the total size of world oil-shale resources were based on few facts, and estimating the grade and quantity of many of these resources were speculative, at best. Oil shales typically contain much larger amounts of inert mineral matter (60-90 percent) than coals, which have been defined as containing less than 40 percent mineral matter. Importantly, unconventional plays account for more than 50 percent of remaining U.S. oil reserves, with Texas alone holding more than 60 billion barrels of recoverable oil in shale plays. Culture of Inflating Oil Reserves Helped Stoke U.S. Shale Boom As the industry reels from the pandemic, some question whether oil reserves were as rich as some companies estimated. To counteract the oil price impact and, at the same time, be able to develop all reserves, the country’s goal aims at reducing operating costs. Lamalginite includes thin-walled colonial or unicellular algae that occurs as laminae with little or no recognizable biologic structures. Argentina’s shale oil reserves – 16.2 billion barrels (60 per cent) – are also one of the largest in the world. Also, areas of Alum Shale in Sweden (locations after Andersson and others, 1985). U.S. gains increased at least 100,000 barrels per day for 10 of the last 16 months. Liquid and gaseous hydrocarbons can be extracted from the oil shale, but the rock must be heated and/or treated with solvents. In this regard, Colombia is preparing new tax incentives and is about to launch free-trade zones (see page 14). Johnson, R.C., Birdwell, J.E., Brownfield, M.E., and Mercier, T.J., 2015, Mass-movement deposits in the lacustrine Eocene Green River Formation, Piceance Basin, western Colorado: U.S. Geological Survey Open-File Report 2015–1044, 13 p., http://dx.doi.org/10.3133/ofr20151044. Results of this study are provided in two publications, below (see 'Data and Tools' for data supporting this assessment): Johnson, R.C., (and U.S. Geological Survey Oil Shale Assessment Team), 2010, Oil Shale Resources of the Eocene Green River Formation, Greater Green River Basin, Wyoming, Colorado, and Utah: U.S. Geological Survey Digital Data Series DDS-69-DD, [CD-ROM]. US is making the most of Shale gas as they have lots of inhabited land. Others have suggested a limit as low as 25 l/t. An in-place assessment of the oil shale and nahcolite resources of the Green River Formation in the Piceance Basin of western Colorado was competed in 2010. Available at: https://doi.org/10.1016/j.fuel.2018.01.107, Johnson, R.C., Birdwell, J.E., Lillis, P.G., 2017, Stratigraphic intervals for oil and tar sands deposits in the Uinta Basin, Utah, The Mountain Geologist, Vol. about its oil and gas reserves. The geologic setting and the physical and chemical characteristics of the resource are of primary importance. By Christopher J. Petherick. ... We have access to over 60,000 contacts in the oil & gas industry. Adding the U.S. estimate of the shale gas technically recoverable resources of 862 trillion cubic feet results in a total shale resource base estimate of 6,622 trillion cubic feet for the United States and the other 31 countries assessed. When oil shale is retorted, the organic matter decomposes into oil, gas, and a residuum of carbon char remaining in the retorted shale. 2014 was a record breaking year as shale oil production across the United States surged, but a new report suggests that trend may be shifting. 2014 was a record breaking year as shale oil production across the United States surged, but a new report suggests that trend may be shifting. More information on Morocco oil shale. S ign U p F or our. Its principal organic component is telalginite derived from the green alga, Gloeocapsomorpha prisca. The fracking of hard-to-reach oil reserves has helped the US regain its crown as the world's top crude oil producer. The technique was subsequently standardized as the American Society for Testing and Materials Method D-3904-80 (1984). Much of the organic matter in oil shale is of algal origin, but may also include remains of vascular land plants that more commonly compose much of the organic matter in coal. However, the U.S. was the world's largest oil … Below are publications associated with this project. Recently, however, attempts have been made to systematically classify the many different types of oil shale on the basis of the depositional environment of the deposit, the petrographic character of the organic matter, and the precursor organisms from which the organic matter was derived. Such materials may be of bacterial origin or the product of bacterial degradation of algae or other organic matter. To be a dominant player in oil world one needs more than oil. Uranium, vanadium, zinc, alumina, phosphate, sodium carbonate minerals, ammonium sulfate, and sulfur are some of the potential byproducts. Shale oil is a substitute for conventional crude oil. The heating value of the oil shale may be determined using a calorimeter. Halite and the sodium bicarbonate mineral nahcolite were deposited in Eocene-age saline Lake Uinta in the Piceance Basin, northwestern Colorado. Extracting shale oil from oil shale is more potentially costly than the production of conventional crude oil both financially and in terms of its environmental impact. The reserves data distinguish between reserves in existing fields and new projects, and potential reserves in recent discoveries and still undiscovered fields. Coaly materials including vitrinite and inertinite are rare to abundant components of oil shale; both are derived from humic matter of land plants and have moderate and high reflectance, respectively, under the microscope. Byproducts may add considerable value to some oil-shale deposits. A report based on documents obtained through a Freedom of Information Act request and published by the nonprofits Partnership for Policy Integrity and Earthworks i… Results of this assessment are available in the following publications (see 'Data and Tools' for data supporting this assessment): Johnson, R.C., Brownfield, M.E., and Mercier, T.J., (U.S. Geological Survey Oil Shale Assessment Team), 2010a, Oil Shale and Nahcolite Resources of the Piceance Basin, Colorado: U.S. Geological Survey Digital Data Series DDS-69-Y [CD-ROM]. Marinite may also contain small amounts of bitumen, telalginite, and vitrinite. Other products that can be made from oil shale include specialty carbon fibers, adsorbent carbons, carbon black, bricks, construction and decorative blocks, soil additives, fertilizers, rock wool insulating material, and glass. To bring some uniformity into this assessment, oil-shale resources in this report are given in both metric tons of shale oil and in equivalent U.S. barrels of shale oil, and the grade of oil shale, where known, is expressed in liters of shale oil per metric ton (l/t) of rock. For US, more than 50% of remaining oil reserves is unconventional shale oil. The processes used for hydrocarbon extraction also produce emissions and waste products that cause significant environmental concerns. The Bakken Field in North Dakota and Montana is the largest producing shale oil reserve. Commercial grades of oil shale, as determined by their yield of shale oil, ranges from about 100 to 200 liters per metric ton (l/t) of rock. Previously published histograms display oil-yield variations with depth and widely correlate rich and lean oil-shale beds and zones throughout the basin.... Below are data or web applications associated with this project. ... We have access to over 60,000 contacts in the oil & gas industry. Saline minerals have been extensively leached by groundwater, and the original... A range of geological parameters relevant to mining oil shale have been examined for the Mahogany zone of the Green River Formation in the Piceance Basin, Colorado, and Uinta Basin, Utah, using information available in the U.S. Geological Survey Oil Shale Assessment database. Enlarge map. The key change factor has been the application, of the existing technique of hydraulic fracturing to the recovery of hydrocarbons from shale formations. These deposits, which range from Cambrian to Tertiary age, may occur as minor accumulations of little or no economic value or giant deposits that occupy thousands of square kilometers and reach thicknesses of 700 m or more. This is perhaps the most common type of analysis that is currently used to evaluate an oil-shale resource. Pennsylvania (103.4 Tcf) Texas (100.8 Tcf) West Virginia (31.7 Tcf) Louisiana (25.6 Tcf) Ohio (24.0 Tcf) Oklahoma (21.4 Tcf) New Mexico (13.1 Tcf) North Dakota (11.7 Tcf) figure data … The estimated in-place nahcolite resource is about 43.3 billion short tons. The Eocene Green River Formation was deposited in two large Eocene saline lakes, Lake Uinta in the Uinta and Piceance Basins and Lake Gosiute in the Greater Green River Basin. Johnson, R.C., (and U.S. Geological Survey Oil Shale Assessment Team), 2010, Oil Shale Resources of the Uinta Basin, Utah and Colorado: U.S. Geological Survey Digital Data Series DDS-69-BB, [CD-ROM]. Estonia and Sweden: Location of the kukersite deposits in northern Estonia and Russia (locations after Kattai and Lokk, 1998; and Bauert, 1994). Their combined recoverable reserves are estimated at about 225 billion cubic metres of gas and 75 million barrels of oil and condensate following interpretation of the exploration drilling results. We can get your products and services seen. It looks at global oil and gas reserves, oil supply and demand, unconventional and frontier oil and gas reserves. It also reviews the economics, the environment and the major shale oil countries. Underlying most definitions of oil shale is its potential for the economic recovery of energy, including shale oil and combustible gas, as well as a number of byproducts. The purpose of this report is to (1) discuss the geology and summarize the resources of selected deposits of oil shale in varied geologic settings from different parts of the world and (2) present new information on selected deposits developed since 1990 (Russell, 1990). The material has not been fully characterized with respect to its composition or origin, but it is commonly an important component of marine oil shales. The Radial Basis Function extrapolation method was used to generate isopach and isoresource maps, and to calculate resources. The following eight states reported the most proved reserves of shale natural gas (Figure 13). More information on Brazil oil shale. The USGS estimates that over 46 billion barrels of oil, 280 trillion cubic feet of gas, and 20 billion barrels of natural gas liquids are trapped in these low-permeability shale formations. These zones are roughly time-stratigraphic units consisting of distinctive, laterally continuous sequences of rich and lean oil shale beds that can be traced throughout much of the Piceance Basin. We produce marketing and networking events for oil and gas businesses and organizations. More information on China, Russia, Syria, Thailand and Turkey oil shale. These materials are composed chiefly of carbon, hydrogen, oxygen, nitrogen, and sulfur. For US, more than 50% of remaining oil reserves is unconventional shale oil. For this reason, it may be necessary to measure vitrinite reflectance from laterally equivalent vitrinite-bearing rocks that lack the algal material. Geothermal maturity of organic matter in oil shale is also determined by the reflectance of vitrinite (a common constituent of coal derived from vascular land plants), if present in the rock. Oil Shale Reserves. Kerogen is a part of rock that breaks down and releases hydrocarbons when heated. Texas alone holds more than 60 billion barrels of shale oil according to this new data. The Green River oil-shale deposits in western United States and a number of the Tertiary lacustrine deposits in eastern Queensland, Australia, are lamosites. The Eocene Green River Formation of Colorado, Utah, and Wyoming contains the largest oil shale deposits in the world. The oil shale deposits are in three structural and sedimentary basins that have been recently assessed: 2010 Piceance Basin in western Colorado 2010 Uinta Basin in eastern Utah and western Colorado 2011 Greater Green River Basin in southwest Wyoming and northwest Colorado The distilled vapors of oil, gas, and water are passed through a condenser cooled with ice water into a graduated centrifuge tube. Marinites are deposited typically in epeiric seas such as on broad shallow marine shelves or inland seas where wave action is restricted and currents are minimal. More information on United States oil shale. Brazil: Deposits of oil shale in Brazil (locations after Padula, 1969). Although shale-oil plays with oil stored in open-fractured shale have been pursued for more than 100 yr, organic-rich and low-permeability shales and hybrid shale-oil systems are now being pursued based on knowledge and technologies gained from production of shale-gas resource systems and likely hold the largest untapped oil resource potential. The drilling of AHT1 H2 well, completed within four months, used 7,000 cm of water as part of the hydraulic fracturing technique used during drilling. Such deposits are generally close enough to the surface to be mined by open-pit, underground mining, or by in-situ methods. In these fields, drillers use multistage fracking to create longer cracks. Torbanite, named after Torbane Hill in Scotland, is a black oil shale whose organic matter is composed mainly of telalginite derived largely from lipid-rich Botryococcus and related algal forms found in fresh- to brackish-water lakes. Oil shale usually meets the definition of "shale" in that it is "a laminated rock consisting of at least 67% clay minerals," however, it sometimes contains enough organic material and carbonate minerals that clay minerals account for less than 67% of the rock. The gross heating value of oil shales on a dry-weight basis ranges from about 500 to 4,000 kilocalories per kilogram (kcal/kg) of rock. The U.S. Geological Survey has used a lower limit of about 40 l/t for classification of Federal oil-shale lands. All that changed in 1998 when Naval Petroleum Reserve No. Up to 1/3 of the rock can be solid organic material. These color differences can be noted by a petrographer and measured using photometric techniques. Public domain.). Commercial grades of oil shale, as determined by their yield of shale oil, ranges from This is usually much less efficient than drilling rocks that will yield oil or gas directly into a well. The Green River Formation was... Introduction Canada: Oil-shale deposits in Canada (locations after Macauley, 1981). However, this method can pose a problem with respect to oil shale, because the reflectance of vitrinite may be depressed by the presence of lipid-rich organic matter. SHALE REMAINS UNTAPPED AFTER DECADES OF FAILURE . The Green River oil shale, for example, is presumed to be the source of the oil in the Red Wash field in northeastern Utah. Johnson, R.C., Dietrich, J.D., and Mercier, T.J., 2015: Updated tops file for Cretaceous and lower Tertiary units, Piceance Basin, northwest Colorado: U.S. Geological Survey Open-File Report 2015–1036, 16 p., http://dx.doi.org/10.3133/ofr20151036. The Devonian-Mississippian oil shales of eastern United States are typical marinites. 54, pp. Lacustrine oil shales include lipid-rich organic matter derived from algae that lived in freshwater, brackish, or saline lakes. Mining oil shale can be either surface mining or in situ retorting. More information on Estonia and Sweden oil shale. Enlarge map. The grade of oil shale has been determined by many different methods with the results expressed in a variety of units. For decades many politicians and scientists have touted Utah’s oil shale as the energy of the future. The estimated in-ground resources are over 300 billion barrels of oil—some of the largest oil-shale resources in the world. Estimated in-place oil is about 1.5 trillion barrels, based on Fischer assay results from boreholes drilled to evaluate oil shale, making it the largest oil shale deposit in the world. Shale oil is a synthetic crude oil produced by retorting oil shale and is the pyrolysis product of the organic matter (kerogen) contained in it. The most abundant and largest deposits are marinites and lamosites. Cannel coals originate in oxygen-deficient ponds or shallow lakes in peat-forming swamps and bogs (Stach and others, 1975, p. 236-237). Events. Tasmanite, named from oil-shale deposits in Tasmania, is a brown to black oil shale. Telalginite is organic matter derived from large colonial or thick-walled unicellular algae, typified by genera such as Botryococcus. The estimated in-ground resources are over 300 billion barrels of oil—some of the largest oil-shale resources in the world. Oil shales were deposited in a variety of depositional environments, including fresh-water to highly saline lakes, epicontinental marine basins and subtidal shelves, and in limnic and coastal swamps, commonly in association with deposits of coal. 2nd challenge: Reducing operating costs. Assuming that the organic matter is subjected to geothermal heating as a function of depth, the colors of certain types of organic matter change from lighter to darker colors. Depths to selected Cretaceous and lower Tertiary stratigraphic units in the Piceance Basin, northwestern Colorado are presented here for 1,563 wells. By Many deposits are not reviewed because data or publications are unavailable. Rankings for natural gas proved reserves from shale in 2018. One technique is to observe the changes in color of the organic matter in samples collected from varied depths in a borehole. The field is roughly the size of West Virginia and, as of December 2012, produced 770,000 barrels of oil a day. Since the oil-price bust of 2014, unpredictability has been the theme music of U.S. shale. You won’t think much of Rio Blanco County if you ever drive through it. Also, oil-shale deposits in Jordan (locations after Jaber and others, 1997; and, Hamarneh, 1998). The drilling of AHT1 H2 well, completed within four months, used 7,000 cm of water as part of the hydraulic fracturing technique used during drilling. Israel and Jordan: Deposits of oil shale in Israel (locations after Minster, 1994). For decades many politicians and scientists have touted Utah’s oil shale as the energy of the future. Variations in the areal extent of saline mineral deposition through time were studied using descriptions of core and outcrop. SHALE OIL AND SHALE GAS POTENTIAL IN COLOMBIA. No data point selected. Enlarge map. Within his three-fold grouping of oil shales (terrestrial, lacustrine, and marine), Hutton (1991) recognized six specific oil-shale types: cannel coal, lamosite, marinite, torbanite, tasmanite, and kukersite. Shale has huge competition to fill remaining oil demand. Importantly, unconventional plays account for more than 50 percent of remaining U.S. oil reserves, with Texas alone holding more than 60 billion barrels of recoverable oil in shale plays. Small amounts of plant resins and waxes also contribute to the organic matter. To counteract the oil price impact and, at the same time, be able to develop all reserves, the country’s goal aims at reducing operating costs. Cannel coal is brown to black oil shale composed of resins, spores, waxes, and cutinaceous and corky materials derived from terrestrial vascular plants together with varied amounts of vitrinite and inertinite.   They perforate short segments of … Such deposits are generally widespread covering hundreds to thousands of square kilometers, but they are relatively thin, often less than about 100 m. Torbanite, tasmanite, and kukersite are related to specific kinds of algae from which the organic matter was derived; the names are based on local geographic features. This appraisal of world oil-shale resources is far from complete. If the size of the resource is expressed only in volumetric units (barrels, liters, cubic meters, and so on), the density of the shale oil must be known or estimated to convert these values to metric tons. Development of new in-situ mining and processing technologies may allow an oil-shale operation in previously restricted areas without causing damage to the surface or posing problems of air and water pollution. Nevertheless, some countries with oil-shale resources, but lack petroleum reserves, find it expedient to operate an oil-shale industry. , Hamarneh, 1998 ) shale that is rich in kerogen usually much less efficient than drilling that...
