Item Regional reservoir characterization and sequence stratigraphy of the Jean Marie Member of the Redknife Formation, northern British Columbia.(2012-11-29) Barclay, Curtis.; Atchley, Stacy C.; Geology.; Baylor University. Dept. of Geology.The Upper Devonian Jean Marie Member of the Redknife Formation in northern British Columbia is an extensive carbonate shelf complex. Porous stromatoporoid boundstones are the primary gas reservoirs, and are stratigraphically trapped beneath and adjacent to the Upper Redknife Shale Member. This study focuses on characterizing reservoir quality and regional distributions through facies description, reservoir attribute mapping, and delineation of the depositional and/or diagenetic controls on reservoir quality. The study is based upon detailed core description of whole core from 80 wells (1556 m of cumulative length), and wireline logs from 156 wells. The Jean Marie reservoir interval is composed of 17 facies grouped within 5 facies associations. The stromatoporoid boundstone ("reef") facies association is concentrated within three distinct, north-trending fairways within the eastern, central, and western portion of the study area. These fairways are interpreted to be the product of a westward prograding carbonate shelf that evolved from a ramp to rimmed shelf through time. The highest reservoir quality within the reef complex coincides with fractured facies characterized by grain-supported textures and associated high interparticle porosity. The spatial distribution of reservoir properties is depicted through cross-sections and maps of facies, grain-supported textures, gross and net porosity thickness, pore-volume thickness, gross interval thickness and fracture density.Item Reservoir assessment of late Devonian Kakisa Formation, northeastern British Columbia, Canada.(2013-05-15) Jones, Kelly N.; Atchley, Stacy C.; Geology.; Barclay, Curtis.; Mintz, Jason S.; Husky Energy.; Baylor University. Dept. of Geology.The Late Devonian Kakisa Formation of northeastern British Columbia, Canada is a high energy, aggradational, discontinuous carbonate bank complex that is composed of three distinct allocycles designated the “Upper”, “Middle”, and “Lower” Kakisa. The study region includes a 5500 square mile area across which the Kakisa was evaluated in regards to the nature and distribution of facies and their relationship to reservoir quality and its spatial distribution. Data integrated into the study include detailed core descriptions for seven wells, and well logs from 116 wells correlated within a grid of 37 cross sections. Gamma ray logs are particularly useful in characterizing petrofacies that are interpreted to have accumulated within low energy, “off-bank” (relatively higher gamma ray activity and lower reservoir quality) and high energy, “on-bank” (relatively lower gamma ray activity and higher reservoir quality) marine settings. The potentially gas-charged reservoir is only associated with “on-bank” stromatoporoid reef complexes observed within the Upper and Middle Kakisa. Reservoir bodies are isolated within the eastern portion of the study area, and coincide with north-trending, high-energy "on-bank" deposits.
