State-owned Sociedade Nacional de Combustíveis de Angola (Sonangol) has authorized block 17 operator Total to award the main contracts to initiate development of the Rosa oil field. Discovered in 1998, Rosa is 135 km off Angola in 1,300-1,500 m of water.
The Rosa development will require 25 subsea wells (14 producers and 11 injectors) tied back to theGirassol FPSO vessel, anchored 15 km away. Modifications to the FPSO will increase the yearly average production rate to 250,000 b/d.
Rosa is the second field to be tied back to theGirassol FPSO, after the Jasmim field in late 2003. It is scheduled to come onstream in the first half of 2007, raising and prolonging the peak production of the Girassol FPSO.
Sonangol is the block 17 concessionaire. Total Angola has a 40% participatory interest in the block, Esso Exploration Angola (block 17) Ltd. 20%, BP Exploration (Angola) Ltd. 16.67%, Statoil Angola block 17 AS 13.33%, and Norsk Hydro 10%.
