Gastem, one of the Utica shale producers, has announced plans to explore for Utica Shale gas across the border in New York state. [11] The Utica shale is a black calcareous shale, from 150 to 700 feet (210 m) thick, with from 3.5% to 5% by weight total organic carbon. The Utica Shale play focuses on an area south of the St. Lawrence River ...
Oil shale formation takes place in a number of depositional settings and has considerable compositional variation. Oil shales can be classified by their composition (carbonate minerals such as calcite or detrital minerals such as quartz and clays) or by their depositional environment (large lakes, shallow marine, and lagoon/small lake settings).
In Canada, the marinite-type of oil-shale deposits include the Devonian Kettle Point Formation and the Ordovician Collingwood Shale of southern Ontario, the Cretaceous Boyne and Favel deposits in the Prairie Provinces of Manitoba, Saskatchewan, and Alberta, and the Anderson Plain and the Mackenzie Delta deposits in the Northwest Territories.
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 ...
Shale gas is an unconventional natural gas produced from shale, a type of sedimentary rock.Shale gas has become an increasingly important source of natural gas in the United States over the past decade, and interest has spread to potential gas shales in Canada, Europe, Asia, and Australia.
Lacustrine deposits are sedimentary rock formations which formed in the bottom of ancient lakes. [1] A common characteristic of lacustrine deposits is that a river or stream channel has carried sediment into the basin. Lacustrine deposits form in all lake types including rift graben lakes, oxbow lakes, glacial lakes, and crater lakes ...
Source rocks are classified from the types of kerogen that they contain, which in turn governs the type of hydrocarbons that will be generated: [1]. Type I source rocks are formed from algal remains deposited under anoxic conditions in deep lakes: they tend to generate waxy crude oils when submitted to thermal stress during deep burial.
48 structural basins with shale gas and oil, in 39 countries, per the U.S. Energy Information Administration, 2011. As of 2013, the US, Canada, and China are the only countries producing shale gas in commercial quantities. The US and Canada are the only countries where shale gas is a significant part of the gas supply.
