Northern Carnarvon Basin—uncover hidden hydrocarbons
Northern Carnarvon Basin is a prolific gas province with oil sweet spots. Despite significant resources identified to date, the basin remains as one of the largest yet-to-find basins in Australasia. Almost all hydrocarbon accumulations discovered to date are reservoired within Upper Triassic, Jurassic, and Lower Cretaceous sandstones and are sealed by the regional Cretaceous Muderong seal.
Despite gas being the main phase of hydrocarbons discovered over the Plateau, the recent liquid discoveries in the adjacent Bedout Subbasin allude to the potential for additional oil-prone petroleum systems in top of the main gas plays.
In partnership with TGS, WesternGeco is providing a Carnarvon multiclient 3D seismic volume, the first contiguous dataset extending from the inboard Mesozoic depocenters of the basin to the outboard Exmouth Plateau. As a result, seismic events and petroleum system elements can now be mapped seamlessly in depth across the basin for the first time.
Ongoing basin modeling and subsurface characterization studies aid to unlock play types across the basin, with deliverables due Q1 2021.
