Project Profile
Value: US$1,400 million
Location: offshore Cabinda in West Africa, Angola
Peak production: 100,000b/d
Water depth: 75m-200m
The Sanha development lies in Block 0, offshore Cabinda in West Africa, in 75m to 200m of water. The US$1.4 billion condensate project is based on a number of fields feeding new facilities on the Sanha field, with LPG connected to a purpose-built FPSO located 30 miles offshore Malongo Terminal. Combined production from Sanha and the nearby Bomboco field reached its average annual peak of 100,000b/d of oil, condensate and LPG in 2007. Combined production from Sanha and the nearby Bomboco field is expected to reach its average annual peak of 100,000b/d of oil, condensate and LPG by 2007.
Block 0 consists of three areas. Area A has 16 developed fields grouped into three complexes: Malongo, Kambala / Livuite and Takula. Gas injection has been introduced at Malongo where NGLs are stripped out on the FGIP compression platform on Malongo West. Area B includes the Kokongo field based on two platforms, one of which, East Kokongo, is included in the Sanha condensate development. This large processing platform forms a transportation hub for all Areas B and C fields. Area C includes the North N\'Dola and South Sanha facilities. North N\'Dola\'s platform is a 16 well-slot facility in 80m of water with a 20,000b/d processing capacity. Crude is exported to East Kokongo while excess gas piped to a flare tower on the 16-slot 40,000b/d South Sanha installation, a 5,460t topsides sitting on a 1,500t jacket. The Sanha condensate project is based on a platform complex in the central Sanha field consisting of a remote flare jacket and process compression installation (PCP), a drilling production platform and a living quarters platform all bridge-linked together. A cryogenic LPG plant on the PCP feeds into the Sanha LPG FPSO located 5km northeast. Any dry residue is compressed and reinjected into the Sanha gas cap.
Chevron Texaco\'s Angolan affiliate, Cabinda Gulf Oil Company (Cabgoc - 39.2%), operates the block on behalf of its partners, including Sonangol (41%), Total (10%), and ENI (9.8%). Cabgoc and Sonasing (a joint venture between Sonangol and SBM) are to share in the operations of the Sanha LPG FPSO.
