Abstract

Commercial accumulations of Ordovician natural gas have been discovered in the Bohai Bay Basin, Ordos Basin and Sichuan Basin of eastern China. The total proved gas reserves account for about 4% of the non-associated gas reserves of P.R. China. Accumulations can be divided into fault-Previous HitblockTop, anticlinal and litho-stratigraphic types. Reservoirs are located in carbonate rocks, and are sourced either from the Ordovician in situ or from the overlying Permo-Carboniferous coal measures.
