Shell made a 100millionbbl, deepwater oil discovery in the Gulf of Mexico, adding to the potential of its Appomattox find. The Vicksburg A discovery is nearby Appomattox, which contains about 500million bbl of potentially recoverable resources.
Vicksburg A is a separate accumulation from both Appomattox and the 2007 Vicksburg B discovery. It is 120km (74.5mi.) offshore in De Soto Canyon block 393 in 2269m (7446 ft) of water. The well was drilled to a total depth of 8042m (26,385 ft) and encountered more than 152m of net oil pay.
