Mobil's wholly owned subsidiary, Mobil Exploration
& Producing Australia Pty Ltd., has found significant new gas resources in the Carnarvon Basin, off the northwest coast of Western Australia
. This follows two recent major discoveries in exploration permit WA-267-P, in which Mobil has a 25 percent interest. The Orthrus-1 well, the second well of a six-well exploration program in the permit, spudded on October 1 in 3,937 ft. (1,200 m) of water. It reached a depth of 11,712 ft. (3,570 m) and has intersected a total of 173 ft. (53 m) net gas pay.
The Orthrus-1 well is located about 16 miles southwest of the Geryon-1 well, the first exploration well in WA-267-P. Geryon-1 was drilled to a total depth of 11,624 ft. (3,543 m). It encountered three gas zones containing good quality sands, with a total net pay of 370 ft. (113 m). Geryon-1 lies in 4,039 ft. (1,231 m) of water.
