This article summarizes results of a recently completed study -- Geological Survey of Canada Bulletin 483 -- of conventional gas resources contained in Triassic strata of the plains portion of the Western Canada basin. The report includes a detailed geological play analysis and numerical assessment of undiscovered gas potential in Part 1, by Bird et al. of the GSC, and an economic analysis, Part 2, by Waghmare et al. of the Energy Sector of Natural Resources Canada in Ottawa. This bulletin on the appraisal of the natural gas potential is part of a series of reports resulting from a comprehensive assessment by GSC of Western Canada gas resources. The Western Canada gas assessment project was divided into seven major play groups on the basis of geological criteria, following major stratigraphic units or structural/tectonic provinces. Each group has a distinct set of geological factors which control size, distribution, and type of hydrocarbon play or reservoir. The major play groups are: the Devonian, Carboniferous-Permian, Triassic, Jurassic to Lower Cretaceous (Mannville), Middle Cretaceous Colorado Group, Upper Cretaceous-Tertiary, and Rocky Mountain foreland belt. About 5% of the discovered in-place gas reserves in the interior plains of Western Canada basin is contained in Triassic rocks. Two-thirds of the discovered in-place gas reserves of the Triassic are contained in the Interior Plains, with the remaining third in Rocky Mountain foreland belt of the Cordilleran Orogen.
