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.
Oil shale is an organic-rich fine-grained sedimentary rock containing kerogen (a solid mixture of organic chemical compounds) from which liquid hydrocarbons can be produced. In addition to kerogen, general composition of oil shales constitutes inorganic substance and bitumens.
In the Paleogene, the Qatar Arch was comparatively stable and Abu Dhabi was at the edge of the Rub al Khali and Pabdeh-Gurpi (centered in the North Emirates) basins. The Hasa Group includes Umm Er Radhuma, Rus and Dammam formations. The Pabdeh Formation is largely offshore and contains 2,200 feet (670 metres) of shale and argillaceous limestone.
As the basin fills up, shallow-water sandstones and continental deposits form. [3] [4] Most of the resulting rocks have little deformation, but near the edge of the mountain chain they can be subject to folding and thrusting. [3] After the basin fills up, continental sediments are deposited on top of the flysch. [4]
The Bazhenov Formation or Bazhenov Shale is a geological stratum in the West Siberian basin. It was formed from sediment deposited in a deep-water sea in Tithonian –early Berriasian time. The sea covered more than one million square kilometers in the central basin area.
Shale is characterized by its tendency to split into thin layers less than one centimeter in thickness. This property is called fissility. [1] Shale is the most common sedimentary rock. [2] The term shale is sometimes applied more broadly, as essentially a synonym for mudrock, rather than in the narrower sense of clay-rich fissile mudrock. [3]
Fossils (various bryozoans) in Ordovician period kukersite oil shale, northern Estonia. Estonian kukersite deposits are one of the world's highest-grade deposits with organic content varying from 15% to 55% with average more than 40%, and it has 65–67% conversion ratio into shale oil and oil shale gas. [1] [11] Fischer Assay oil yield is 30 ...
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.
