MELBOURNE, Oct. 19 -- A Chevron Australia group has made a gas discovery in the Carnarvon basin off Western Australia which is likely to boost reserves available to its Gorgon and Wheatstone LNG projects.

The group’s successful Achilles-1 wildcat was drilled in permit WA-374-P immediately south of Io/Jansz field and west of Gorgon field.

The well, drilled by the Ensco 7500 semisubmersible rig, intersected 100 m of net gas pay in Triassic Mungaroo sandstone.

The well is part of a 10-well campaign being carried out by the group in Australia this year.

The Ensco rig has moved to the next location, also in WA-374-P, called Satyr-1.

Chevron has a 50% interest in the permit, which lies 160 km northwest of Onslow in the Greater Gorgon Area. ExxonMobil and Shell each have 25%.
