HOUSTON -- Anadarko Petroleum has made a pre-salt discovery at the Wahoo prospect offshore Brazil in the Campos basin. The 1-APL-1-ESS well is located on block BM-C-30 in approximately 4,650 ft (1,417 m) of water approximately 25 mi (40 km) southeast and syncline separated from Petrobras' previously announced pre-salt discoveries at the Jubarte field.
Preliminary results at Wahoo, based on wireline logs, indicate at least 195 ft (59 m) of net pay with similar characteristics to the nearby Jubarte 1-ESS-103A well, the company says.
"Our first operated pre-salt test in Brazil is a resounding success as we're seeing data that mirrors other very significant pre-salt discoveries in this prolific area," says Bob Daniels, Anadarko Sr. VP of worldwide exploration. "It's still early in the process, and we plan to continue drilling toward additional targeted objectives to a total depth of approximately 20,000 ft (6,096 m).
The positive results so far provide encouragement and validate our decision to relocate the drillshipDeepwater Millennium to Brazil to execute our ongoing pre-salt exploration program, which includes at least four additional wells in the deepwater Campos and Espirito Santo basins through the middle of next year."
The Wahoo well is currently drilling at approximately 18,400 ft (5,608 m). In order to fulfill the work program, the company has run a full suite of wireline logs including porosity tools.
Anadarko and its partners plan to conduct additional logging, including pressure and fluid sampling, once the well reaches total depth, with the potential to conduct a drillstem test at a later date. Following operations at Wahoo, Anadarko anticipates moving the vessel to the Serpa prospect on BM-ES-24 to re-enter the prospect where the initial well encountered pre-salt hydrocarbon-bearing zones in secondary objectives and did not reach the primary objective because of rig limitations.
