The recompletion, in Section 6-20s-27e, was drilled to a total depth of 4,595 ft. and plugged back to 4,075 ft.

11 A deepwater discovery has been reported to IHS Inc. by Anadarko Petroleum Corp. of The Woodlands, Texas. Located on Green Canyon Block 432, Anadarko encountered 120 ft. of pay in high-quality Miocene sands. Known as the Samurai discovery, the #1 OCS G32504 was drilled to a total depth of approximately 31,700 ft. The surface location is in the west-central portion of Block 432 in 3,390 ft. of water.
