BOTH Chevron and Woodside bolstered their respective operations offshore Western Australia with new gas discoveries in April, the companies announced.

Chevron’s Isoceles 1 exploration discovery well found gas about 95 kilometres northwest of Barrow Island, in the Carnarvon basin offshore northwest Australia.

The well found about 134 metres of net gas pay in the Triassic Mungaroo Sands in 968 metres of water, Chevron announced.

The well fulfilled the second year work commitment in the exploration program over the WA 392 P permit area, which Chevron operates with a 50 per cent stake.

Shell and Mobil Australia Resources each hold a 25% stake in the permit.

Chevron Asia Pacific Exploration and Production Company president Melody Meyer said the discovery was an important addition to the company portfolio.

“This discovery is a continuation of our exploration success and further positions our company as a key supplier for future liquefied natural gas (LNG) demand in the Asia-Pacific region,” she said.

The news came after Woodside announced it had hit gas with its Pyxis 1 exploration well in production licence WA 34 L, located within the Dampier sub basin.

That, in turn, is located about 15 kilometres north of Woodside’s Pluto gas field infrastructure, company executive vice president of global exploration Philip Loader said.

“Given its location, this successful exploration outcome offers future tie-back potential to Woodside’s existing Pluto infrastructure,” he said in an announcement.

The well hit about 18.5 metres of net gas in the Jurassic sandstone after reaching a total depth of 3,347 metres.

Woodside holds a 90% operating stake in WA 34 L, with Kansai Electric Power and Tokyo Gas each holding 5% stakes.
