BP Announces Chumbo Discovery In Deepwater Angola

Sociedade Nacional de Combustíveis de Angola (Sonangol) and BP announced the Chumbo 1 oil discovery in the deepwater Block 18, offshore Angola. This was the second discovery in 2003 and eighth overall in the block.

The Chumbo-1 well was drilled by the semi-submersible drilling rig, the Leiv Eiriksson, in 1,600 meters water depth some 200 kilometers off the Angolan coast. The well flowed at a rate of 1,080 barrels per day in a test undertaken to evaluate the oil formation. Further work will be needed to evaluate the full extent of the Chumbo 1 discovery, that lies some 10 kilometers to the south southwest of the Platina–1 oil discovery in the same block.

Block 18 was awarded in the middle of 1996 by Sonangol to Amoco as Operator and Shell, with a 50 per cent equity each. Following the merger between BP and Amoco in 1999, BP now manages the interest formerly held by Amoco.

BP operates Block 18, which contains the Greater Plutonio project. BP has 50 per cent equity in the block, Shell also has 50 per cent.

BP also operates Block 31 with a 26.67 per cent interest together with partners Esso Exploration and Production Angola (Block 31) limited 25 per cent, Sonangol E.P. 20 per cent, Statoil Angola A.S. 13.33 per cent, Marathon Petroleum Angola Block 31 Limited 10 per cent, and EPA (Block 31) Ltd (a member of the Total group of companies) 5 per cent.

BP's other interests in Angola are:

Block 15 operated by Esso (BP 26.67 per cent equity), which contains the Kizomba A and B fields that are now being developed.

Block 17 operated by Total (BP 16.67 per cent equity), which contains the Girassol field, which came on stream in December 2001 and the Dalia field, which was approved for development by Sonangol in May 2003.
