South Wales coalfield (CBM and shale) shale basin
South Wales coalfield (CBM and shale) is one of the UK onshore shale basins on Brent & Beyond. Carboniferous Coal Measures (CBM) above middle-Carboniferous shales of Bowland age; much less data than in England.
Gas in place is not recoverable gas. No UK recovery factor has been established; years of supply need a recovery factor first.
