SERIES OF OIL DEVELOPMENTS GETS GO AHEAD

IN ANGOLA BLOCK 31

Sociedade Nacional de Combustíveis de Angola - Sonangol E.P. - has authorised BP and its co-venturers to develop a series of deepwater oil discoveries in offshore Angola's Block 31. 

The Block 31 developments programme is based on a standardised development concept, which is intended to reduce cycle time, optimize capital and maximise operating efficiency through standardised design, fabrication and commissioning. 

The first project in the programme will comprise the Plutão, Saturno, Vênus and Marte (PSVM) fields which lie in the north east sector of Block 31, in a water depth of approximately 2000m, some 400 kilometres north west of Luanda. Construction work is expected to start during 2008 with first oil planned in 2011 and building to a plateau of about 150,000 barrels per day by 2012.

The operator (BP) and its co-venturers have announced fifteen discoveries in Block 31 to date. Full development will comprise multiple hubs similar to the first development (PSVM). The second development will be in the SE area of Block 31 and is in the planning phase. 

BP Exploration (Angola) Limited as operator holds 26.67 percent. The other interest owners in Block 31 are Esso Exploration and Production Angola (Block 31) Limited (25 percent), Sonangol EP (20 percent), Statoil Angola A.S. (13.33 percent), Marathon International Petroleum Angola Block 31 Limited (10 percent) and TEPA (Block 31) Limited with 5 percent. Sonangol E.P. is the concessionaire. 

Note to editors

PSVM will comprise a converted hull floating, production, storage and offloading vessel (FPSO) with 1,600,000 barrels of storage capacity; 48 production, gas and water injection plus infill wells; 15 manifolds and associated subsea equipment; 170 kilometres of flowlines and 95 kilometres of control umbilicals.

Key contracts are ready to be awarded following programme sanction.

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

BP's involvement with Angola goes back to the mid 1970s. BP has interests in four blocks with operatorship of two.

PSVM is the second BP-operated development in Angola after Block 18's Greater Plutonio which came on stream in October 2007. BP has a 50% interest in Block 18.

BP's non-operated interests are in Block 15, operated by Esso Exploration Angola (Block 15) Limited (BP 26.67 per cent equity); and Block 17 operated by Total (BP 16.67 per cent equity).
