Gulf of Mexico Success at Shell's Vicksburg "A" Well

Gulf of Mexico Success at Shell's Vicksburg "A" Well July 3, 2013 (Hague) - Shell today announces a successful exploratory well atVicksburg in the deepwater Gulf of Mexico. The well is located 75 miles (120kilometers) offshore in the De Soto Canyon Block 393 in 7,446 feet (2,269meters) of water. It was drilled to a total depth of 26,385 feet (8,042 meters)and encountered more than 500 feet (152 meters) of net oil pay. In total, the Vicksburg "A" discovery is estimated to hold potentiallyrecoverable resources of more than 100 million barrels of oil equivalent(mmboe). It adds to the more than 500 mmboe of potentially recoverableresources that have already been discovered and appraised at the nearbyAppomattox discovery. Vicksburg "A" is a separate accumulation from bothAppomattox and the 2007 Vicksburg "B" discovery. "The results of the Vicksburg well strengthen our existing deepwater Gulf ofMexico exploration portfolio and should contribute to the nearby Appomattoxdiscovery," said Mark Shuster, Executive Vice President Shell Upstream AmericasExploration. Shell (the operator with a 75% interest) and Nexen, a wholly-owned subsidiaryof CNOOC Limited, (25% interest), are following up the Vicksburg "A" well witha sidetrack well to test the Corinth prospect, a separate fault block from theVicksburg discovery. Further exploration drilling targeting tie-backs toAppomattox will follow. # # # Enquiries: Shell Media Relations: International +44 207 934 5550Americas +1 713 241 4544 Shell Investor Relations: International +31 70 377 4540North America +1 713 241 1042 Cautionary Note The companies in which Royal Dutch Shell plc directly and indirectly ownsinvestments are separate entities.
