HOUSTON, Mar. 2
– Apache Northwest Pty. Ltd. is shooting 46.1 sq km of 3D seismic on the WA-399-P block in the Exmouth basin on Australia’s Northwest Shelf, said partner Jacka Resources Ltd.

The Gazelle 3D survey is to cover 89% of the permit. Apache designed it to extend beyond the permit and into WA-42-L to take advantage of local, key well control. Apache will fully fund the 9-12-day project.

WA-399-P lies on the Novara arch, a proven oil and gas trend. An estimated 680 million bbl of oil reserves and 1.2 tcf of gas reserves have been discovered downdip of WA-399-P in Pyrenees, Stybarrow, Vincent, and Van Gogh oil fields and Macedon gas field.

Updip of WA-399-P, the Leatherback and Ridley oil accumulations demonstrate that the Novara arch hydrocarbon migration fairway likely extends through the permit.

The primary target of the Gazelle 3D is the Gazelle lead, a Muderong formation subcrop play with a combination structural-stratigraphic trapping style similar to that already proven successful in adjacent fields and elsewhere in the North Carnarvon basin. The Gazelle 3D seismic data will be used to mature the lead and investigate some potential Direct Hydrocarbon Indicators identified on recently reprocessed 2D seismic lines.
