Abstract

Summary

We collected a large dataset of gas samples recovered from shale formations around the world and interpreted the origin of shale gases using recently revised gas genetic diagrams. Gas in most shale plays has thermogenic origin. Some shale plays contain secondary microbial gas. Primary microbial gas is not common in shale play.
