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]
Shale gas is one of a number of unconventional sources of natural gas; others include coalbed methane, tight sandstones, and methane hydrates. Shale gas areas are often known as resource plays [27] (as opposed to exploration plays). The geological risk of not finding gas is low in resource plays, but the potential profits per successful well ...
The deposit is one of the world’s highest-grade deposits with more than 40% organic content and 66% conversion ratio into shale oil and gas. The oil shale is located in a single calcareous layer 2.5 to 3 metres (8.2 to 9.8 ft) in thickness and is buried at depths from 7 to 100 metres (23 to 328 ft). [6]
The Marcellus is an example of shale gas, natural gas trapped in low-permeability shale, and requires the well completion method of hydraulic fracturing to allow the gas to flow to the well bore. The surge in drilling activity in the Marcellus Shale since 2008 has generated both economic benefits and environmental concerns—and thus ...
The Haynesville Shale is overlain by sandstone of the Cotton Valley Group and underlain by limestone of the Smackover Formation. [3] [4] It contains vast quantities of recoverable natural gas. This natural gas is known as "shale gas" because the wells produce from low permeability mudstones that are also the source for the natural gas. It was ...
Cases of long distance oil migration into shallow traps away from the "generative depressions" are usually found in foreland basins. Besides pointing to zones of high petroleum potential within a sedimentary basin, subsurface mapping of a source rock's degree of thermal maturity is also the basic tool to identify and broadly delineate shale gas ...
Shale gas and condensate is produced from the Duvernay Formation in central Alberta using horizontal drilling and multi-stage hydraulic fracturing. [5] $2 billion was paid for leases during 2010 and 2011. Prices for land remained high as of June, 2012 despite costs of drilling being expensive. Parts of the deposit show total organic carbon of ...
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 ...
