The Raven River Member of the Cardium Formation in the Garrington Field is a petroliferous, late-cretaceous unit composed of heterogeneous, bioturbated sandstones and mudstones. Researchers attempted to optimize various drilling and completion parameters, but a multivariate analysis of how geological, drilling and completion variables affect early hydrocarbon production has not been examined. This study uses a combination of sedimentology, sequence stratigraphy and statistics to determine the influence of these variables on 12 month production. Core and wireline log data were used to construct a sequence stratigraphic framework, and geologic maps including net sandstone, net pay, and H. The geologic maps alone were poor predictors of 12 month production, from where midpoint pressure, natural fracture analysis, and drilling and completion variables are included in a statistical analysis. The statistical analysis concludes that 12 month production correlates strongest with the completion length, the number of stages completed, drilling in zone, and pressure.
