The Triassic section of northwest Alberta and northeast British Columbia consists of an eastward thinning sediment wedge composed of siliciclastics, evaporites and carbonates bounded above and below by the major unconformity surfaces of the pre-Jurassic, pre-Cretaceous and post-Palaeozoic.
The Triassic section in the study area is made up of the Montney, Doig, Charlie Lake and Baldonnel formations and each of these formations are further subdivided into a number of correlatable intervals and units. Delineation of the units within the section is complicated by a number of unconformity surfaces that converge towards the east and cross-cut the strata at a number of levels. These truncation surfaces provide the major trapping mechanism for many of the porous units within the Triassic section and as such the section within the study area offers considerable undiscovered potential for hydrocarbons from a number of stratigraphic intervals.
The study area is located in northwest Alberta and northeast British Columbia and encompasses an area of approximately 15,000 square kilometres from the S.E. corner of Township 86 Range 4W6 to the N.W. corner of 94-H-16. Triassic production occurs from the Baldonnel, Charlie Lake, Doig and Montney formations within the study area. At the time of the study 704 wells penetrated the Triassic section, and core from 119 wells (over 2400 metres) was described and interpreted.
