Petrology and Reservoir Paragenesis in the Sussex 'B' Sandstone of the UpperCretaceous Cody Shale, House Creek and Porcupine Fields, Powder River Basin, Wyoming

摘要

Using petrologic and sedimentologic studies, the paper characterizes theinfluence of sedimentologic and petrologic variations on reservoir heterogeneity in the Sussex 'B' sandstone in the House Creek and Porcupine fields, Powder River Basin, Wyoming. Effects of authigenic minerals on reservoir properties are described in detail for selected inter-ridge and ridge facies sandstones.
