COURBEVOIE, France --Angola's deepwater Rosa field in block 17 has gone on production, according to Sonangol, Total, and Statoil.

In 1,350 m (4,429 ft) of water 135 km (84 mi) off Angola, Rosa produces via a 15 km (9.3 mi) tieback to theGirassol FPSO. Daily output from Girassol, including Rosa, will be 270,000 barrels of oil at plateau. Rosa's reserves are estimated at 370 MMbbl of oil and will contribute to Girassol maintaining plateau production for several years, according to the partners.

Rosa field will comprise 25 wells, including 11 water injection and 14 producers, tied into four manifolds. The subsea installation consists of 64 km (40 mi) of insulated production flowlines and of 40 km (25 mi) of water injection lines linking Rosa to theGirassol FPSO. An riser tower near the FPSO takes the fluid over 1,200 m (3,937 ft) from the sea floor to the surface.

Sonangol is the block 17 concessionaire. Total E&P Angola, operator, has a 40% interest, alongside partners Esso Exploration Angola (Block 17) Ltd. (20%), BP Exploration (Angola) Ltd. (16.67%), Statoil Angola Block 17 AS (13.33%), and Norsk Hydro Dezassete AS. (10%).
