Sociedade Nacional de Combustiveis de Angola (Sonangol) and BP Exploration (Angola) Limited have announced the Dione oil discovery in ultra-deepwater Block 31, offshore Angola.

This is the sixteenth discovery made by BP in Block 31 and is located in the southern portion of the block, about 9 kilometers to the southwest of the Juno-1 discovery.

Dione was drilled in a water depth of 1696 meters, some 390 kilometers northwest of Luanda and reached a total depth of 3272 meters below sea level. The well was spudded in April 2008 and drilled by the Transocean's GSF Explorer drillship. 

The well test results confirmed the capacity of the reservoir to flow in excess of 5,000 barrels a day under production conditions.

Sonangol is the concessionaire of Block 31 and owns 20% equity. BP Exploration (Angola) Limited as operator holds 26.67%. The other interest owners in Block 31 are Esso Exploration and Production Angola (Block 31) Limited (25%); Statoil Angola A.S. a subsidiary of StatoilHydro ASA (13.33%); Marathon International Petroleum Angola Block 31 Limited (10%); and TEPA (BLOCK 31) Limited, a subsidiary of the Total Group (5%). 

BP has interests in four Angolan blocks with operated interests in two and has a 13.6% interest in the Angola LNG project.

Operatorship of Block 31 was awarded to BP Exploration (Angola) Limited in May 1999. The Block covers an area of 5,349 square kilometers and lies in water depths of between 1,500 and 2,500 meters.

BP also has operated interests (BP 50% equity) in Block 18 where Greater Plutonio started production on October 1, 2007.

BP has non-operated interests in Block 15, operated by Esso Exploration Angola (Block 15) Limited (BP 26.67% equity) and in Block 17 operated by Total (BP 16.67% equity).
