Officer

Commentary

The Officer remains poorly explored, with limited seismic and few wells. Federal approvals have become more supportive, but gas-market intervention and safeguard-mechanism costs weigh on frontier investment. Outlook: Neutral.

Location

Description

The AOB is located in Western Australia and South Australia and covers about 410,000 sq. km, containing a sediment thickness of up to 10,000m. There are several major depocenters which makes up a number of easily identifiable sub basins.

Summary

The Basin is poorly explored, with only about 15,000km of 2D seismic coverage and less than 30 exploration wells. Numerous hydrocarbon shows from four distinct oil families are recorded from Neoproterozoic and Cambrian sediments, but there have been no commercial discoveries. Possible traps range from simple anticlinal closures, diapirs and fault-induced rollovers as well as stratigraphic traps.
