Stratigraphic and structural analysis of the Waterton Foothills (T1-8, R27W4-3W5M) indicates that the Alberta and lower Blairmore Groups hold hydrocarrbon potential near the south of the international border. Prospective units are sublitharenites-litharenties and lithic pebble conglomerates that range in thickness from 5 to 25 m. Thrust faults duplicate all or part of these units and can account for up to six repetitions of sandstone and conglomerate at one locality. Surface geological mapping at a scale of 1:50,000 formed the basis for the subsurface study. Subsurface information included 150 well logs, eight cores, and chip sampels from 18 wells. These data were used in a structural interpretation along with projected surface data and seismic. Structural geometires are shown by two balanced and palinspastically restored structural cross sections. Units within the Alberta and Blairmore groups have tested/showed oil, condensate, and gas throughout the study area. When put into a structural and stratigraphic framework, potential areas for hydrocarbon exploration can be delineated in the footwall of the Harland Lakes/Livingstone thrust where the Cardium sandstone has been shown to be well developed. Key hydrocarbon shows are confined to the same structural level in the Blairmore and Alberta groups (including the Beaver Mines, Cardium, and Blacksone formations and possibly the Cadomin Formation).
