PARIS -- Total has begun redeveloping the Anguille field in Gabon.
Anguille is located 20 km (12 m) offshore Port-Gentil in a water depth of 30 m (98 ft) in the Grand Anguille Marine concession. Discovered in 1962, Anguille came onstream in 1966 and produced 7,500 b/d in 2007 prior to redevelopment.
According to Total, the redevelopment project will improve the oil recovery factor from 13% to 23% by increasing the number of drainage points and by enhancing well productivity using hydraulic fracturing and massive waterflood.
Phase 1 of redevelopment is under way, using existing facilities. Around a dozen wells will be drilled in 2007 and 2008, and the associated surface facilities will be debottlenecked.
Running from 2009 to 2011, Phase 2 entails installing new offshore infrastructure and decommissioning obsolete process units, building an onshore plant (power generation, fluid treatment, gas compression) and drilling an additional 30 wells.
The project will eliminate gas flaring on the field by 2011, as well as coastal discharges of production water.
Production is expected to increase from 2008, peaking at over 30,000 b/d in 2013-2014. The development cost is an estimated $2 billion for additional proved and probable reserves of around 150 MMbbl.
