contact us· What is shale gas and how much is there globally? Shale gas is a form of natural gas (mostly methane), found underground in shale rock. It is classified as ''unconventional'' because it is found in shale, a less permeable rock formation than sandstone, siltstone or limestone in which ''conventional'' gas is found, and it is generally distributed over a much larger area.
