Shale deposits

Oct 19, 2023 · 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. .

Shale outcrop from the northern Norway. Hammer for scale. Mud covering a dry riverbed in La Palma, the Canary Islands. The main ingredient of shale is clay which is here on the way from the disintegrated rock higher in the mountains to the sea where it will be finally deposited. Rivers do the hard job of carrying all the mud to the ocean.Oil shale is a sedimentary rock. As it reaches its oil window, oil shale releases a liquid known as shale oil. Oil shale is the rock from which shale oil is extracted. Shale oil is similar to petroleum, and can be refined into many different substances, including diesel fuel, gasoline, and liquid petroleum gas ( LPG ).Although shale oil in today’s (1999) world market is not competitive with petroleum, natural gas, or coal, it is still used in several countries that possess easily exploited deposits of oil shale but lack other fossil fuel resources. Some oil shale deposits contain minerals and metals that may have by-product value.

Estimated shale oil and shale gas resources in the United States and in 137 shale formations in 41 other countries represent 10% of the world's crude oil and 32% of the world's natural gas technically recoverable resources, or those that can be produced using current technology without reference to economic profitability, according to a new EIA ...Advocates of the syn-sedimentary timing have termed these shale-hosted deposits “SEDEX” (sedimentary exhalative: Carne and Cathro 1982), historically the most commonly used term for these deposits. Given the significant debate as to the timing of mineralization, we prefer to use a purely descriptive term such as “shale-hosted” rather ...The Vaca Muerta Shale is a continuous tight oil and shale gas reservoir of Late Jurassic ( Tithonian) and Early Cretaceous ( Berriasian) age. The formation covers a total area of 30,000 square kilometres (12,000 sq mi). [10] The shale is at a depth of about 9,500 feet (2,900 m), where it has been found productive of oil and gas.

By 2035, shale oil production could "boost the world economy by up to $2.7 trillion, a PricewaterhouseCoopers (PwC) report says. Shale oil, in fossil fuel production, either a synthetic crude oil that is extracted from oil shale by means of pyrolysis or a naturally occurring crude oil that is extracted from underground shale deposits by means of fracking (hydraulic fracturing). In the extraction of oil from oil shales,

Jun 6, 2014 · The Marcellus Shale, one of the largest sources of natural gas in the U.S., and perhaps the second largest in the world, may contain 500 trillion cubic feet of gas. Today, there are 45,000 shale gas wells operating in the U.S. and natural gas production is expected to increase 56 percent between 2012 and 2040. Apr 22, 2019 · When the oil shale deposits form the direct floors of the coal seams (Fig. 7), these assemblages have generally developed during the mid-late stages of a basin’s evolution. The oil shale deposits are mainly developed in lakeside-shallow lake and even deep lake environments.
