Shale Gas Resources Evaluation of the Songliao Basin

Abstract

The Qingshankou and Nenjiang group in upper cretaceous of Songliao basin is a set of dark shale. Analyze the shale thickness, organic matter type, organic matter abundance, vitrinite reflectance, mineral composition of the permo-carboniferous coal-bearing strata. Consider that the thickness of shale in the Songliao basin is larger, despite the organic matter abundance is good, but maturity is lower, less of the formation of oil and gas.
