Shale forms important reservoirs for low-volume natural gas in some places. Gas in shales may be generated thermogenically or biogenically3, 10. The gas may occur as free gas in fractures, as gas sorbed onto kerogen and clay-particle surfaces, or as gas dissolved in organic remains or hydrocarbons within the shales10. The shales are organic rich and act as the source rock as well as the
