The Lower Cretaceous Skull Creek Shale is an organic-rich unit that was deposited under anaerobic conditions in the restricted Western Interior Seaway. Because of its organic richness and thermal maturity, it is a candidate as a shale-gas play. However, it appears that the high proportion of Type III organic matter and low porosity degrade the possibility that it could generate or produce commercial quantities of hydrocarbons. The major objective of this paper is to present a preliminary characterization of the Skull Creek Shale as a shale-gas system.
