Log-Derived Regional Source-Rock Characteristics of the Woodford Shale, Anadarko Basin, Oklahoma

摘要

The Woodford Shale is an organic-rich, highly compacted, 'black' shale of Late Devonian and Early Mississippian age that is widely regarded as a major hydrocarbon source rock in the Anadarko basin of Oklahoma. The report describes regional depositional trends and organic-carbon content of the Woodford Shale as evidenced by wire-line logs in the Oklahoma portion of the Anadarko basin. The relation between depositional patterns and organic-carbon content is discussed, and the mass and distribution of organic carbon in thermally immature and mature areas of the Woodford Shale is estimated.
