Abstract
Until recently very few data were available on the permeability of shale samples. Those available were mainly obtained by those interested in top seal capacity, overpressure retention or radioactive waste disposal. The shale gas revolution, which has taken place in the USA over the last decade, has meant that the amount of data available on shale permeability has increased by several orders of magnitude; although it is important to note that “shale” gas reservoirs tend to have far less clay than shale seals to petroleum reservoirs and overpressured compartments. The experimental methods used by those involved in the shale gas industry differ significantly from those involved in seal analysis.
