Chevron, partners reveal major test in deepwater GOM On Sept. 5, a consortium of Chevron (operator, 50%), Devon Energy (25%) and Statoil (25%) announced a record-setting production test on the Jack 2 well in Walker Ridge Block 758 of the US Gulf of Mexico (GOM). Jack 2 was drilled to delineate the Jack 1 discovery that encountered 350 net ft of pay in September 2004. Jack 2 was drilled and tested in about 7,000 ft of water and more than 20,000 feet below the sea floor, with a TD of 28,175 ft (Jack 1’s TD was 29,000 ft). Tested during second-quarter 2006, Jack 2 flowed more than 6,000 bopd, and the test represented about 40% of the well’s total net pay. Although the partners officially referred to Jack’s test results as “encouraging,” analysts are already estimating preliminary reserves at 3 billion bbl of oil on the low side and 15 billion bbl on the high side.
