HOUSTON, Apr. 24 -- Recent appraisal drilling has confirmed the Constitution and Hornet oil fields in the deepwater Gulf of Mexico, reported Kerr-McGee Corp., which owns 100% of both fields.
Constitution lies in 5,000 ft of water on Green Canyon block 680, and Hornet, in 3,850 ft of water on Green Canyon block 379.
"The (Constitution) pay sands are high quality oil reservoirs, with 25-30% porosity and greater than 30° gravity oil," Kerr McGee reported. The initial well, drilled to 13,727 ft, encountered more than 100 ft of net oil pay in a shallow Plio-Pleistocene objective.
The confirmation well, 4,000 ft northwest, was drilled to 15,213 ft and encountered 375 ft of net oil pay in Plio-Pleistocene sands, primarily in deeper objectives not tested in the discovery well. The well is being sidetracked downdip, 1,650 ft to the southwest, to test for additional deeper reservoirs, and another appraisal well is planned.
The appraisal well in Hornet field encountered more than 275 ft of net pay in Plio-Pleistocene sands. It is being sidetracked 2,300 ft to the northwest onto Green Canyon Block 335 to define the aerial extent of the reservoirs. High quality oil and gas reservoirs were confirmed on both the northeast and northwest flank of a salt-supported feature.
