Two petroleum systems are recognised in the Northern Carnarvon Basin where the Upper Jurassic Dingo Claystone and Triassic Locker Shale - Mungaroo formations are effective source rocks.
The petroleum system charts for the Exmouth, Barrow and Dampier Sub-basins show that almost all of the oil and gas accumulations are reservoired within Upper Triassic, Jurassic and Lower Cretaceous sandstones beneath the regional Early Cretaceous seal.
