Santos announced a gas discovery at the Winchester-1 exploration well in WA-323-P, located in the Carnarvon Basin offshore Western Australia.

Winchester is Santos' fourth consecutive exploration gas discovery offshore Western Australia, following successes at Crown, Bassett West and Bianchi.

Wireline logging and pressure testing has confirmed 40 metres of net gas pay in the Jurassic Angel and Triassic Mungaroo formations between 3,614 and 3,721 metres. Multiple gas samples have been recovered and are being analysed.

Winchester is located approximately 135 kilometers northwest of Dampier in a water depth of 75 metres.

Santos Head of Exploration Bill Ovenden said wireline logging has confirmed a gas discovery with excellent reservoir quality at Winchester.
