Offshore staff
HOUSTON -- Anadarko has drilled an oil discovery at its West Tonga field on Green Canyon block 726 in 4,700 ft (1,433 m) of water. The discovery well, drilled to TD of 25,680 ft (7,827 m), encountered over 350 ft (107 m) of net oil pay in three high-quality subsalt Miocene sands, according to Anadarko.
Anadarko operates West Tonga with a 37.5% working interest. Partners include StatoilHydro with a 25% working interest, Chevron with a 20.5% working interest, and Shell with a 17% working interest.
"The West Tonga discovery continues the success of our deepwater GoM exploration program and further illustrates the value of our extensive hub-and-spoke infrastructure," says Bob Daniels, Anadarko Sr. VP of worldwide exploration.
"West Tonga is indicative of our exploration program in the deepwater Gulf, which focuses on prospects in the Miocene and Lower Tertiary plays that have estimated recoverable resources of more than 100 MMboe. Coupled with the Caesar discovery (Anadarko 20%, Shell 62.5%, and StatoilHydro 17.5%), West Tonga gives Anadarko and our partners two significant fields that potentially could be tied back to theConstitution spar."
Anadarko also is drilling the Atlas prospect on Walker Ridge block 155 and the Terrebonne prospect on Green Canyon block 452. Atlas is a 30,000-ft (9,144-m) lower Miocene test, operated by Anadarko with a 68% working interest. Repsol E&P USA Inc. has a 20% working interest and Ridgewood Energy Corp. holds a 12% working interest.
Woodside Energy USA Inc.-operated Terrebonne is a 26,000-ft (7,925-m) upper Miocene test. Anadarko has a 33.33% working interest in Terrebonne. Plains Exploration & Production Co. holds a 25% working interest.
