Viking Formation
The Viking Formation is a stratigraphical unit of Cretaceous age in the Western Canadian Sedimentary Basin. It takes the name from the town of Viking, Alberta, and was first described in the Viking- Kinsella oil field by Dowling in 1919. Lithology The Viking Formation is composed of fine to coarse grained sandstone with interbeds of conglomerate and cherty conglomeratic sandstone. Nodular phosphorite, coal fragments and concretionary siderite occur in the coarse beds. Hydrocarbon production Oil is produced from the Viking Formation in eastern and central Alberta as well as in west-central Saskatchewan. The Viking Formation had an initial established recoverable oil reserve of 88.7 million m³, with 66.8 million m³ already produced as of 2008. Gas reserves totaled 277.9 million e³m³ (or 227,900 million m³), with 103.4 million e³m³ (or 103,400 million m³already produced.

Geological Formation
A geological formation, or simply formation, is a body of rock having a consistent set of physical characteristics ( lithology) that distinguishes it from adjacent bodies of rock, and which occupies a particular position in the layers of rock exposed in a geographical region (the stratigraphic column). It is the fundamental unit of lithostratigraphy, the study of strata or rock layers. A formation must be large enough that it can be mapped at the surface or traced in the subsurface. Formations are otherwise not defined by the thickness of their rock strata, which can vary widely. They are usually, but not universally, tabular in form. They may consist of a single lithology (rock type), or of alternating beds of two or more lithologies, or even a heterogeneous mixture of lithologies, so long as this distinguishes them from adjacent bodies of rock. The concept of a geologic formation goes back to the beginnings of modern scientific geology. The term was used by Abraham Gottlob Wer ...

Petroleum
Petroleum, also known as crude oil, or simply oil, is a naturally occurring yellowish-black liquid mixture of mainly hydrocarbons, and is found in geological formations. The name ''petroleum'' covers both naturally occurring unprocessed crude oil and petroleum products that consist of refined crude oil. A fossil fuel, petroleum is formed when large quantities of dead organisms, mostly zooplankton and algae, are buried underneath sedimentary rock and subjected to both prolonged heat and pressure. Petroleum is primarily recovered by oil drilling. Drilling is carried out after studies of structural geology, sedimentary basin analysis, and reservoir characterisation. Recent developments in technologies have also led to exploitation of other unconventional reserves such as oil sands and oil shale. Once extracted, oil is refined and separated, most easily by distillation, into innumerable products for direct use or use in manufacturing. Products include fuels such as gasol ...

British Columbia
British Columbia (commonly abbreviated as BC) is the westernmost province of Canada, situated between the Pacific Ocean and the Rocky Mountains. It has a diverse geography, with rugged landscapes that include rocky coastlines, sandy beaches, forests, lakes, mountains, inland deserts and grassy plains, and borders the province of Alberta to the east and the Yukon and Northwest Territories to the north. With an estimated population of 5.3million as of 2022, it is Canada's third-most populous province. The capital of British Columbia is Victoria and its largest city is Vancouver. Vancouver is the third-largest metropolitan area in Canada; the 2021 census recorded 2.6million people in Metro Vancouver. The first known human inhabitants of the area settled in British Columbia at least 10,000 years ago. Such groups include the Coast Salish, Tsilhqotʼin, and Haida peoples, among many others. One of the earliest British settlements in the area was Fort Victoria, established ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horn River Formation
The Horn River Formation (also ''Horn River Shale'') is a stratigraphic unit of Devonian (early Givetian to late Frasnian) age in the Western Canadian Sedimentary Basin. It is a thick sequence of marine sediments that was first described in outcrop on the banks of the Horn River, a tributary of the Mackenzie River, in the Northwest Territories (at the time District of Mackenzie) by Whittaker in 1922, and it takes its name from that river. In 1963 it was redefined in the subsurface of the Fort Nelson area of British Columbia (well Fort Nelson a-95-J/94-J-10) by F.F. Gray and J.R. Kassube. It is significant for its shale gas resources. Lithology The Horn River Formation is composed of dark siliceous and calcareous shale, and argillaceous bituminous limestone. Stratigraphy The Horn River Formation is included in the Beaverhill Lake Group. It is subdivided into the following members, from top to base: * Muskwa Member: bituminous, mildly radioactive shale * Otter Park Member ...

Bakken Formation
The Bakken Formation () is a rock unit from the Late Devonian to Early Mississippian age occupying about of the subsurface of the Williston Basin, underlying parts of Montana, North Dakota, Saskatchewan and Manitoba. The formation was initially described by geologist J. W. Nordquist in 1953. The formation is entirely in the subsurface, and has no surface outcrop. It is named after Henry O. Bakken (1901–1982), a farmer in Tioga, North Dakota, who owned the land where the formation was initially discovered while drilling for oil. Besides the Bakken formation being a widespread prolific source rock for oil when thermally mature, significant producible oil reserves exist within the rock unit itself. Oil was first discovered within the Bakken in 1951, but past efforts to produce it have faced technical difficulties. In April 2008, a USGS report estimated the amount of recoverable oil using technology readily available at the end of 2007 within the Bakken Formation at 3.0 ...

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. The well was drilled north of Fort St. John, immediately east of the Alaska Highway. Lithology The formation is composed of siltstone and dark grey shale, with dolomitic siltstone in the base and fine grained sandstone towards the top. The facies is shaley in the north and west of the extent ( Fort St. John), silty in the center (Dawson Creek and Pouce Coupe areas) and becomes coarser ( sandy) in western Alberta ( Valleyview area). Oil and gas production The Montney Formation is a major shale gas and tight oil resource. A comprehensive joint study on the potential of the Montney Formation was completed by the National Energy Board, British Columbia Oil and Gas Commission and the Alberta Energy Regula ...

Duvernay Formation
The Duvernay Formation is a stratigraphical unit of Frasnian age in the Western Canadian Sedimentary Basin. It was first described in well Anglo Canadian Beaverhill Lake No. 2 in LSD 11-11-50-17W4M by Imperial Oil staff in 1950. The formation was named by Andrichuk and Wonfor in 1954 for the type section in Duvernay, Alberta. According to Canada's Alberta Energy Regulator, the Duvernay Formation "holds an estimated 443 trillion cubic feet of gas and 61.7 billion barrels of oil (Penny China Institute 2012-12)." Calgary-based, Athabasca Oil Corporation (formerly Athabasca Oil Sands Corporation), holds 640,000 acres, the largest publicly disclosed Duvernay rights. Lithology The Duvernay Formation is composed of laminated bituminous shale, calcareous shale and dense argillaceous limestone. Pyrite disseminations are common. Calcarenite and coral rich mudstone are also present. Hydrocarbon production The Duvernay Formation represents the source rock for prolific reservoirs such ...

Cardium Formation
The Cardium Formation is a stratigraphic unit of Late Cretaceous age in the Western Canada Sedimentary Basin. It takes the name from the fossilized heart-shaped cockle shells in the family Cardiidae (from Greek ''kardiā'', "heart") present. It was first described along the Bow River banks by James Hector in 1895.as reported in Whiteaves, J.F. 1895, Some of the Cretaceous fossils collected during Captain Palliser's explorations in British North America in 1857-60. Proc. and Trans., Royal Society of Canada, 2nd Ser., vol. 1, pp. 110. It is present throughout western Alberta and in northeastern British Columbia, and it is a major source of petroleum and natural gas. Lithology The Cardium Formation is composed primarily of beds of massive, fine-grained to conglomeratic sandstone, which are separated by thick layers of shale. The formation is subdivided into the following members from top to base: *Sturrock Member (sandstone) *Leyland Member (shale) *Cardinal Member (sandstone) *Kis ...
