Abstract

The Upper Devonian Duvernay Formation represents one of the most important sources of conventional oil within the Western Canada Sedimentary Basin. It is an organic-rich, basinal shale and limestone sequence within the Upper Devonian Woodbend Group. Several lithofacies from the Duvernay Formation have been identified in this study. This study concentrated on the shales and mudstones of the Duvernay Formation. The terrestrial material is probably derived from the area to the north or northwest. The major diagenetic processes that affected shales and mudstones lithofacies are cementation, dolomitization and pyritization. Minor processes include physical compaction, dissolution, anhydritization and fracturing. Framboidal pyrite, non-ferroan calcite cement and matrix dolomite are of early diagenetic origin. Bacterial sulphate reduction is the main process of bacterial reduction. (Abstract shortened by UMI.)Dept. of Earth Sciences.
