Carbonate reservoir rocks in the Mid-Late Proterozoic McArthur Group

Abstract

Original Studies of hydrocarbon occurrence discounted McArthur Group for the following reasons, lack of source rock, overmature sediments, lack of seal and reservoir rocks. This report proposes the McArthur Group can be considered prospective for the following reasons good oil prone alginitic source rocks, hydrocarbon shows large sections of source rocks are presently submature to mature for oil generation and the presence of reservoir rocks. Speculative assessment of reservoir potential is based on stratigraphic history and structural geology.
