This study provides an understanding of the depositional evolution of the Leduc-Camrose-Nisku interval in order to better understand it’s hydrocarbon potential. The study successfully documents the depositional facies and sedimentation patterns that govern the distribution of productive and postulated play-types within the study area. In particular it extends the prospective play fairway of the Wood River pinnacle/shelf outlier (Nisku ‘G’ Pool) occurrences further south. Inclusive is a systematic mapping of this embayment or “moat” system. It is significant in that it outlines another potential Nisku play-type, namely shelf edge closure.
The study area is located in southern Alberta, centered on the Drumheller area, from Townships 25 to 36 between Ranges 15W4 and 29W4. At the time of the study, a total of 1012 wells penetrated the Nisku Formation within the study area. Cored intervals from 214 wells (over 5260 metres) were described at the AEUB Core Research Centre for this study.
