Apache Northwest has completed the acquisition of the 3D seismic programme covering the WA-399-P exploration permit within the Carnarvon Basin, offshore Western Australia.

WA-399-P lies adjacent to the Pyrenees Oil development, which began oil production in February 2010.

Apache has a 60% interest in the permit, with Jacka Resources holding 15%, Carnarvon Petroleum 13% and Rialto Energy 12%.

The seismic data will be processed and interpreted before the joint venture determines the form of any future exploration programme.

Apache Northwest, the permit’s operator, funded the full cost of the seismic data acquisition programme under a previously announced farm-in agreement.
