Santos Limited announced it has made a gas discovery at the Winchester-1 exploration well in Permit WA-323-P in the Carnarvon Basin, off Western Australia.
The Winchester-1 well, located approximately 84 miles (135 kilometers) northwest of Dampier in a water depth of 246 feet (75 meters), is Santos' fourth consecutive exploration gas find off Western Australia, following successes at Crown, Bassett West and Bianchi.
Santos said that wireline logging and pressure testing has confirmed 131 feet (40 meters) of net gas pay in the Jurassic Angel and Triassic Mungaroo formations between 11,857 and 12,209 feet (3,614 and 3,721 meters). Multiple gas samples have been recovered and are being analyzed.
Santos Head of Exploration Bill Ovenden said that wireline logging has confirmed a gas discovery with excellent reservoir quality at Winchester.
“Winchester-1 will now be deepened to evaluate the gas-bearing potential of further objectives within the Mungaroo section,” Ovenden said in a press release.
Santos Vice President Western Australia and Northern Territory John Anderson said a gas discovery at Winchester is a significant outcome, and potential commercialization options could include the expansion of Santos’ existing production through jointly owned infrastructure, or alternatively via proximal existing third party LNG infrastructure, which surrounds WA-323-P.
Santos holds 75 percent of WA-323-P and is the operator. The remaining interest is held by Octanex N.
The company farmed-in to the block in June 2011.
