The Moose Mountain area, situated along the front range of the Canadian Rockies, 32 miles northwest of the Turner Valley oil field, Alberta, has interested oil companies for a great many years. Its main feature is a large domal structure, approximately 10 miles long and 3 miles wide, that has been drilled at three widely separated locations, resulting in two producers and a failure. These tests were started only a few hundred feet above the Mississippian-Devonian contact. The dry hole was drilled about 2,700 feet below the top of the Cambrian; the producers are deriving the gas and oil from rocks
of Devonian age. There are limestone zones in the lower part of the Devonian that are extremely porous where they crop out north and south of the Moose Mountain area; but the pore spaces were found to be filled with calcite in beds that were stratigraphically equivalent to these zones where they were encountered, structurally high, in the McColl-Frontenac Oil Company's test on the Moose Mountain anticline.
