Depositional interpretation and sequence stratigraphic control on reservoir quality and distribution in the Meramecian Sooner trend Anadarko Basin, Canadian, and Kingfisher Counties (STACK) play, Anadarko Basin, Oklahoma, United States

摘要

The Mississippian Meramecian play in the greater Sooner trend Anadarko Basin, Canadian, and Kingfisher Counties (STACK) play region is an unconventional reservoir in the Anadarko Basin in westcentral Oklahoma. The play is a fine-grained system composed of quartz silt and sand with varying amounts of carbonate grains and clay. The primary driver of reservoir quality is the quantity of calcite cement. Large volumes of cement are found in coarser-grained, higher-energy facies, whereas porosity is preserved in lower-energy facies, imparting a strong depositional control on reservoir quality.
