Definition of oil shale in English English dictionary: a dark-brown or black shale, from which petroleum-like hydrocarbons can be produced by distillation; shale from which oil can be obtained by heating; Shale that is rich in hydrocarbon derivatives, In the United States, a significant oil shale is the Green River Formation, in the Rocky Mountain region; A fine-grained, sedimentary rock that contains kerogen, a partially formed oil Kerogen can be extracted by heating the shale, but at a very high cost; A black or dark brown shale containing hydrocarbons that yield petroleum by distillation. Any fine-grained sedimentary rock that contains solid organic matter (kerogen) and yields significant quantities of oil when heated. This shale oil is a potentially valuable fossil fuel, but the present methods of mining and refining it are expensive, damage the land, pollute the water, and produce carcinogenic wastes. Thus, oil shale will probably not be exploited on a wide scale until other petroleum resources have been nearly depleted. Estonia, China, and Brazil have facilities for producing relatively limited quantities, and the U.S. government operates an experimental plant in Colorado; sedimentary rock containing solid organic material that can be converted to crude oil which is called shale oil; A sedimentary rock containing kerogen, a solid organic material; A dark-grey or black shale that contains organic substances that yield hydrocarbons, but does not contain free petroleum; A brown or black clastic source rock containing kerogen
shale oil: a crude oil, containing hydrocarbons, obtained by the distillation of oil shale
oil shales: layers of condensed oil
shale oil: A crude oil that is obtained from oil shale by heating and distillation. Synthetic crude oil that is extracted from oil shale by pyrolysis, or destructive distillation. The oil obtained from oil shale cannot be refined by the methods that have been developed for crude oil, however, because shale oil is low in hydrogen and contains large amounts of nitrogen and sulfur compounds. To be made usable, shale oil must be hydrogenated and then chemically treated to remove the nitrogen and sulfur, a process too expensive to make shale oil commercially competitive with crude oil.

shale oil: crude oil from oil shale derived by heating
shale oil: oil extracted from oil shale by heating
