Browse Basin Regional Geology

Regional Geology of the Browse Basin

The Browse Basin is a northeast-trending Paleozoic to Cenozoic depocentre situated offshore on Australia’s North West Shelf. The basin is being actively explored with four Mesozoic petroleum systems being identified. Several large gas accumulations are currently under development for liquefied natural gas (LNG) and condensate production. Current contingent resources are estimated at 31 MMbbl (5 GL) of crude oil, 595 MMbbl (95 GL) of condensate, 383 MMbbl (61 GL) of LPG and 25 Bcf (713 Bcm) of gas (Geoscience Australia, 2015).
