How is Shale Gas Produced?

2013-4-30 · Shale gas formations are "unconventional" reservoirs – i.e., reservoirs of low "permeability." Permeability refers to the capacity of a porous, sediment, soil – or rock in this case – to transmit a fluid. This contrasts with a "conventional " gas reservoir produced from sands and carbonates (such as limestone).
