As source rocks for most conventional oil reservoirs, oil shale deposits are found in all world oil provinces, although most of them are too deep to be exploited economically. [27] As with all oil and gas resources, analysts distinguish between oil shale resources and oil shale reserves.
Oil shale formation takes place in a number of depositional settings and has considerable compositional variation. Oil shales can be classified by their composition (carbonate minerals such as calcite or detrital minerals such as quartz and clays) or by their depositional environment (large lakes, shallow marine, and lagoon/small lake settings).
Oil shale geology is a branch of geologic sciences which studies the formation and composition of oil shales–fine-grained sedimentary rocks containing significant amounts of kerogen, and belonging to the group of sapropel fuels. [1] Oil shale formation takes place in a number of depositional settings and has considerable compositional variation.
The oil shale industry is an industry of mining and processing of oil shale—a fine-grained sedimentary rock, containing significant amounts of kerogen (a solid mixture of organic chemical compounds), from which liquid hydrocarbons can be manufactured.
The Vaca Muerta Shale is a continuous tight oil and shale gas reservoir of Late Jurassic and Early Cretaceous 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.
Martin Yates' company first struck oil 100 years ago 15 miles southeast of the small town of Artesia in southeast New Mexico, paving the way for what became known as the “shale revolution ...
The Autun oil shale deposit is a sedimentary basin containing oil shale of the Autunian age (between 299 and 282 million years old) ...
