Situated 75 m (120 km) offshore in the Mississippi Canyon block 525 in 7,479 ft (2,280 m) of water, the Rydberg well was drilled to TD of 26,371 ft (8,038 m). TheNoble Globetrotter Idrillship drilled the well, encountering more than 400 ft (122 m) of net oil pay.
Shell is evaluating the well results but expects the resource base to be about 100 MMboe. The Norphlet discovery, combined with the Appomattox and Vicksburg discoveries, brings the total potential to more than 700 MMboe.
The Rydberg discovery is about 10 m (16 km) of the planned Appomattox development.
This is the first discovery for the partnership of Shell (operator, interest 57.2%), Ecopetrol America Inc. (28.5%), and Nexen (14.3%), a wholly owned affiliate of CNOOC Ltd.
