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.
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]
The Woodbine overlies the Maness Shale, Buda Limestone, or older rocks, and underlies the Eagle Ford Group or Austin Chalk. In outcrop the Woodbine Group has been subdivided into the Lewisville Sandstone, Dexter Sandstone, and/or Pepper Shale formations. [ 1 ]
The Haynesville Formation, from which the Haynesville Shale gets its name, was named after the town of Haynesville, Claiborne Parish, Louisiana.The type location for Haynesville Formation, is the Hunt Oil Company No. 1 well in Haynesville oil field, sec. 3, T. 23 N., R. 7 W., Claiborne Parish, Louisiana.
The Piceance Basin contains one of the thickest and richest oil shale deposits in the world and is the focus of most on-going oil shale research and development extraction projects in the U.S. The Piceance Basin has an estimated 1.525 trillion barrels of in-place oil shale resources, and an estimated 43.3 billion tons of in-place nahcolite ...
The Pottsville Formation consists of a gray conglomerate, fine to coarse grained sandstone, and is known to contain limestone, siltstone and shale, as well as anthracite and bituminous coal. [ 4 ] [ 5 ] It is considered a classic orogenic molasse . [ 6 ]
Eastern North America in the Middle Devonian, showing the Michigan Basin of the Rheic Ocean. In Michigan, the Bedford Shale is found in the southeast along shores of Lake Erie and Lake St. Clair; along the shore of Lake Huron north of Saginaw Bay; along the south shore of the Straits of Mackinac; north of 44 degrees latitude along the shore of Lake Michigan; and in the far southwest corner of ...
The shales (and slates) of the Martinsburg were deposited in a large forearc basin resulting in a flysch deposit. This basin was the result of a deepening sea due to the closing of the Iapetus Ocean. Turbidites are common in the Martinsburg due to underwater landslides stirring up sediments and rushing down a slope. Limestones were deposited ...
