The Triassic section of northeast British Columbia comprises an under exploited sequence that has significant exploration potential.  The stratigraphic complexity of the section necessitates detailed stratigraphic analysis for successful exploration.  Seismic analysis of the section alone is generally incapable of resolving the stratigraphic complexities observed and is limited in its ability to define the exploration targets.  The stratigraphic complexities observed are directly related to the many unconformity surfaces that characterize the Triassic section.  At least seven erosional events are recognized within the Triassic section in northeastern British Columbia, and the overall effect of these is to remove section towards the northeast as unconformities converge.

The study area is located in northeast British Columbia  and encompasses an area of approximately 19,400 square kilometres from the S.E. corner of Township 86 Range 13W6 to the N.W. corner of 94-H-4.  A data base of 1773 wells and core from 199 wells (over 3400 metres) was used to interpret the stratigraphic relationships within the study interval.  The result is a comprehensive understanding of the stratigraphy, depositional units and exploration potential of the Doig, Halfway and Charlie Lake formations.  It evaluates and extends all presently known play-types as well as contributes to a better understanding of future and potential play areas.
