Apache Northwest has spud the Zola-1 well in permit WA-290-P, located in the offshore Carnarvon Basin. The Stena Clyde semisub is drilling the well, and operations should take about 40 to 50 days to reach a proposed total depth of around 16,404 feet (5,000 meters).
Zola is a very large Triassic tilted fault block on trend with the Gorgon gas field. Considered one of the largest un-drilled structural features in the Carnarvon Basin, Zola is covered by high quality newly reprocessed 3D seismic data and is considered a moderate risk prospect. It is estimated that Zola contains between 0.2 and 2 Tcf of recoverable gas with a mean volume of nearly 1 Tcf.
Apache operates WA-290-P, holding a 30% interest; Nippon Oil Exploration holds 25%; OMV Australia holds 20%; Santos Offshore holds 15%; and Tap holds 10%.
