The Salawati Basin is the most prolific oil basin in Eastern Indonesia. More than 500 exploratory and developrrle~~t wells have been drilled and around 300 tnilliorl barrels of oil produced from 15 fields.Oil typing indicates that tlte oils of the Salawati basin are similar and were generated from the same source rock type. Recent geochemical analyses suggest that the oils were sourced from kerogen rich in fresh-brackish water algae and higher plants with a significant input of marine type 11, sulphur rich kerogen.The Miocene marine Klasafet and Klamogun shales and carbonates have been regarded as the source rocks for the oils now trapped in reefs of the Miocene Kais Formation. However it is possible that the oils have more than orle source. Potential soul-ce rocks in the Salawati Basin are the Klasafet and Klamogun Formations (Miocene), Sirga Formation (Oligocene), Kembelangan (Cretaceous-Jurassic), Tipuma (Triassic) and Aifam( Permian)Formations.The oil of the Salawati Basin may corlsist of a mixture of oils generated from these formation and migrated into the Kais Formation during the Plio Pleistocene.
