Santos and its partners have encountered gas pay in the Zola-1 exploration well, which is located in the WA-290-P permit in the Carnarvon Basin, offshore Western Australia.

The firms hit a gas pay of 100m over a 400m gross interval in the primary target, the Mungaroo Formation.

Zola-1, which is located 27km south-west of Gorgon-1 at a water depth of 280m, is on trend with the Gorgon gas field and is situated near a developing gas infrastructure.

Santos vice-president of exploration and subsurface Trevor Brown said Santos will work to quickly appraise the discovery.

Santos holds a 24.75% share of WA-290-P. Apache is the operator with a 30.25% stake, OMV Australia holds a 20% share, Nippon Oil Exploration has a 15% stake and Tap Oil holds 10%.
