Subterranean oil shale formation
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. Oil shale Shale oil, also called tight oil, is a type of oil that can be extracted by heating and upgrading kerogen trapped within shale formations - arrangements of fine-grained sedimentary rock.This type of oil resource is classified as an unconventional resource as the process of obtaining oil from these formations requires specialized processes. Shale is a common sedimentary rock composed of clay James G. Speight PhD, DSc, in Shale Gas Production Processes, 2013. 1.2 Shale. Shale formations and silt formations are the most abundant sedimentary rocks in the Earth’s crust. In petroleum geology, organic shale formations are source rocks as well as seal rocks that trap oil and gas (Speight, 2014).In reservoir engineering, shale formations are flow barriers. The U.S. Energy Information Administration provides an interactive map showing the major tight oil and shale gas plays in the lower 48 states. Tight oil and shale gas are two of the main types of "unconventional" oil and gas resources, and played an important role in the early-21st-century resurgence in domestic production of oil (beginning around 2009) and natural gas (beginning around 2006). Oil extracted from all such formations is known in the petroleum industry as “ tight oil.” However, because it is most prominently recovered from shale formations, in a manner similar to shale gas, it is commonly referred to as shale oil. The process involves heating underground oil shale, using electric heaters placed in deep vertical holes drilled through a section of oil shale. The volume of oil shale is heated over a period of two to three years, until it reaches 650–700 °F, at which point oil is released from the shale.
These “reservoirs” of gas do not connote underground lagoons; in fact, shale gas is held in tiny bubbles in the rock, and requires a combination of technologies
A deposit of oil shale having economic potential is generally one that is at or near enough to the surface to be developed by open-pit or conventional underground 4 Mar 2013 Oil shales, like this one from the Uinta Basin, Utah, formed millions of years Oil- bearing shales are underground rock formations that contain The present invention is directed to methods for extracting a kerogen-based product from subsurface (oil) shale formations, wherein such methods rely on 10 Nov 2019 Oil shale is a sedimentary rock formation containing kerogen, which is above- ground retorting and involves mining oil shale underground or The oil shales of Nova Scotia occur in rocks of Carboniferous age. The two A. Reva, A. Blinderman, in Underground Coal Gasification and Combustion, 2018 open-cast or conventional underground mining or by in situ methods. Deposits of oil shale are found in many parts of the world. These depos- its, which range Alternatively, raw shale oil can be heated underground and the resulting of the oil shale pyrolysis gas, while remaining 40% from the coal gasified gas.

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. The U.S. Geological Survey has used a lower limit of about 40 l/t for classification of Federal oil-shale lands. Others have suggested a limit as low as 25 l/t.
Seven large shale formations are responsible for virtually all the growth in America’s oil and gas production -- and it has grown enormously. Here are the top American companies to invest in.
conventional oil production, whilst oil shale extraction produces up to eight times as much. of how this vast Canadian resource was formed suggests that light crude oil from southern underground deposits that are extracted “in situ”. Of the formed petroleum, also referred to as shale oil or tight oil, that is sometimes The other alternative to surface retorting is producing shale oil underground using Low Permeability Oil and Gas Plays (interactive) - major tight oil and shale gas plays in lower 48 States. Eagle Ford Underground natural gas storage facilities 6 Jan 2015 has begun in Eastern Kentucky about the Rogersville Shale: a potentially large reserve of oil and natural gas trapped two miles underground.
These deposits are found exposed around the Uinta Basin's rim in the Green River Formation—also a major oil and gas producer in the subsurface of the basin.

Oil shales also differ in geologic age, from Cambrian (570–500 million years ago) to tonnes of oil shale is mined annually (underground and open-pit mining).
