Gas Shales

Gas shales are fine grained rocks where the predominant gas storage mechanism is sorption and gas is stored in volumes that are potentially economic. Since the sorption capacity is mainly related to surface area and the microporous organic fraction has the highest surface area, gas shales are of necessity organic rich.  Rocks included in this definition of gas shales are organic rich, true shales, mudrocks (non-fissile rocks comprised mainly of clays), siltstone, and very fine-grained sandstones.  In many basins gas shales are gradational with tight sands.
