BP Confirms Deepwater Discovery Offshore Angola

Sonangol and BP have discovered oil with the Plutao well in the ultra-deepwater Block 31, offshore Angola. This is the second exploration well BP has drilled in Block 31.

The well was tested at a maximum rate of 5,357 barrels a day of oil through a 48/64ths-inch choke. Further work will be needed to evaluate the full extent of the Plutao discovery.

Block 31 and its operatorship was awarded in 1999 by Sonangol to BP with a 26.67% equity together with its partners Esso (25%), Sonangol (20%), Statoil (13.33%), Marathon (10%) and TotalFinaElf (5%). The Block covers an area of 5,349 square kilometers and lies in water depths of between 1,500 and 2,500 meters.

Plutao-1 was drilled by the semi-submersible drilling rig, the Leiv Eiriksson, in 2,020 meters water depth, approximately 175 kilometers off the Angolan coast and reached a total depth of 4,100 meters below sea level. Plutao is 36 kilometers to the west of the Hungo-1 discovery in Block 15 (Esso operated, BP 26.67%). BP also operates Block 18, in which it has a 50% equity (the other partner being Shell). In Block 18 the Greater Plutonio Project is currently being progressed through front end engineering and design (FEED).
