Outcrop of Ordovician kukersite oil shale, northern Estonia Lower Jurassic oil shale near Holzmaden, Germany. 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.

Montney Formation. The Montney Formation is a stratigraphical unit of Lower Triassic age in the Western Canadian Sedimentary Basin in British Columbia and Alberta.. It takes the name from the hamlet of Montney and was first described in Texaco's Buick Creek No. 7 well by J.H. Armitage in 1962. [3]
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.
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 Woodbine Group was first mapped and named by Robert T. Hill, known as the "Father of Texas Geology", for outcrops near the small town of Woodbine, Texas in 1901. [2] The Woodbine represents ancient river and delta systems that originated from erosion of the Ouachita Uplift in modern-day Oklahoma and Arkansas and the Sabine Uplift in modern ...
It is well known as the host rock for major deposits of shale oil and shale gas. The large oil discovery in the Vaca Muerta Formation was made in 2010 by the former Repsol-YPF . [ 1 ] The total proven reserves are around 927 million barrels (147.4 × 10 ^ 6 m 3 ), [ 2 ] and as of 2014 YPF 's production alone was nearly 45,000 barrels per day ...
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]
The Marcellus Formation or the Marcellus Shale is a Middle Devonian age unit of sedimentary rock found in eastern North America.Named for a distinctive outcrop near the village of Marcellus, New York, in the United States, [3] it extends throughout much of the Appalachian Basin.
