The application of surface geochemistry to a basal Cretaceous clastic pool on the Alberta-Montana border has shown that geochemical anomalies can be distinguished in and around areas overlying oil pools. The type of work included helium, calcium, and various hydrocarbon ratios. In addition, gravity, magnetic, electrical, and seismic work was also done over the survey area. The results of this work suggest that seismic is by far the most accurate tool in delineating hydrocarbon traps. Some current geochemical techniques available to the industry are evaluated to perhaps supply the uninitiated with an idea of the use and potential of these methods.
