Phase III of a major regional evaluation of the Wabamun Group in Alberta and British Columbia.. This phase deals with the hydrocarbon potential of the Crossfield Member of the Wabamun Formation. The objectives include developing a stratigraphic and depositional framework for the Wabamun in the area, as well as illustrating the distribution of Wabamun hydrocarbons and key compostional variations indicating possible controls. Objectives also include determining on a local scale the lateral hydraulic continuity and extensions of existing Wabamun gas pools, as well as on a regional scale the degree of vertical and horizontal hydraulic continuity and the effect it has on gas emplacement.
