Oil shale is a type of sedimentary rock that is rich in kerogen. Kerogen is a part of rock that breaks down and releases hydrocarbons when heated. Hydrocarbons are substances made entirely of hydrogen and carbon. Petroleum and natural gas are probably the most familiar hydrocarbons. The hydrocarbons in oil shale can be used as an alternative to petroleum or natural gas. Numerous deposits of oil shale, ranging from Precambrian to Tertiary age, are present in the United States. The two most important deposits are in the Eocene Green River Formation in Colorado, Wyoming, and Utah and in the Devonian-Mississippian black shales in the eastern United States. The oil shale interval in the Piceance Basin is subdivided into seventeen “rich” and “lean” zones and each interval was assessed for variations in gallons per ton, barrels per acre, and total barrels in each 36-square mile township. These zones are roughly time-stratigraphic units consisting of distinctive, Deposits of oil shale are in many parts of the world. 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. Most natural gas production growth is expected to come from shale gas and tight oil plays March 22, 2016 Wells drilled since start of 2014 provided nearly half of Lower 48 oil production in 2015
The rock is of Ordovician age. The reserves of oil shale are enormous (nearly 1000 times more energy is stored in oil shales than in coal deposits 2) but so far it has found little use because better alternatives like coal, crude oil, and natural gas are available. The main problem with oil shale is purity. As Shale Wells Age, Gap Between Forecasts and Performance Grows Already, U.S. oil-production growth is moderating, and the economies of oil-producing regions softening. By 2021, IHS expects
In the six decades or so of oil-shale studies on the Green River Formation ( Paleocene—Eocene) in northeast Utah, northwest Colorado, and southwest
3 Dec 2015 There are at least three reasons why shale oil makes OPEC production cuts a less palatable, less effective and less practical policy tool than in 6 Apr 2014 But getting at that oil isn't easy. The Monterey Shale is unlike other oil shale formations across the United States. In those booming oil fields, 20 Jul 2017 A minority of oil shale is formed in lacustrine environments, such as the Green River Formation of Colorado and Utah and the Wilkins Peak 29 Mar 2012 Since the shale in North Dakota and Texas is producing oil, some have assumed that the Green River Formation and its roughly 2 trillion Their test is called the freeze wall. The United States sits on the world's largest oil shale deposit in the Green River Formation. Alaska also has a huge oil shale Oil shale began formation millions of years ago by the deposition of silt and organic debris on lakebeds and sea bottoms. Oil shale rich in organic content is dark Oil shale is an organic-rich fine-grained sedimentary rock containing kerogen from which liquid hydrocarbons can be produced, called shale oil. Shale oil is a substitute for conventional crude oil; however, extracting shale oil from oil shale is more costly than the production of conventional crude oil both financially and in terms of its environmental impact. Deposits of oil shale occur around the world, including major deposits in the United States. A 2016 estimate of global deposits set the t

Now, the group is making another bold gamble on America's oil revolution: that its golden age An oil shale, which has a very high proportion of organic matter in relation to mineral matter, is categorized as a coal.
