Apache Corporation announced that its North Gipsy-1 discovery offshore Northwest Australia tested at a rate of 5,940 barrels per day of 44.9 degree API crude oil from a 63-foot interval between 7,336 feet and 7,399 feet in the late Triassic-age Brigadier
sandstone. The partners are Kufpec with 19.3 percent and Tap Oil with 12.2 percent and Apache with a 68.5 percent working interest in the discovery. The well was drilled by the Ensco 56. The discovery of oil at North Gipsy increases the likelihood of early development of the Gipsy/Rose/Lee complex, which is located 10 miles east-northeast of Apache's established oil and gas processing and export facilities at Varanus Island. Gas-condensate accumulations have been confirmed in Rose and Lee and oil in the North Rankin Formation in Gipsy. The discoveries are in Production License Area TL/1 in the Barrow Sub-basin of the Carnarvon Basin. The North Gipsy-1 well was tested on a 56/64-inch choke with 1,065 pounds per square inch of flowing tubing head pressure. The test was restricted by surface equipment limitations. Apache has four other prospects east of the discovery, where it plans to drill additional wildcats to test the same geologic concept.
