AbstractThe Middle Devonian to Upper Mississippian Besa River Formation (currently being elevated to a group by other authors) is a thick (300-1000 m) gas-prone succession of organic-rich basinal shales, bedded chert, and fine-grained limestone widely preserved in the Liard Basin of British Columbia, Yukon Territory, and Northwest Territories. The Besa River contains a major frontier shale-gas prospect in the Famennian to lower Tournaisian Exshaw Member and underlying informal Patry unit. The internal stratigraphic framework of the Besa River is poorly known and warrants intensive study because of its substantial economic significance. This report provides illustrated descriptions, lithologs, and spectral gamma surveys of one outcrop and three cored sections of the Besa River in the Liard Basin of B.C. and in the adjacent western part of the Horn River Basin. This study is part of the joint activity of Geological Survey of Canada, Korea Institute of Geoscience and Mineral Resources (KIGAM), and Filippo Ferri of B.C. Ministry of Natural Gas Development.
Summary(Plain Language Summary, not published)
The Middle Devonian to Middle Mississippian Besa River Group of Liard Basin is a thick (300-1000 m) gas-prone sequence of organic-rich basinal shales located in British Columbia, Yukon, and Northwest Territories. The Besa River is a thick (300-1600 m) frontier shale prospect requiring better stratigraphic framework. This report is part of the joint GSC-KIGAM activity in the Liard Basin compiling detailed illustrated descriptions, striplogs, and spectral gamma surveys of outcrop and cored sections of the Besa River Group and its equivalents in the adjacent areas. These materials have not been published previously or were published incompletely.
