Total announces that its subsidiary Total Upstream Nigeria Limited (TUPNI), operator of the OML 130 block, has started production from its Akpo deep water development ahead of the planned start-up date. With proved and probable reserves estimated at 620 millions barrels of condensate (around 50° API), and more than 1 tera cubic feet (tcf)* of gas, Akpo is one of the largest deep offshore projects ever undertaken and will be the largest brought on stream in 2009.

This start-up provides further evidence of the Group’s capacity to meet the technology challenges of deep offshore, an area in which Total’s track record is already ranked among world leaders.

The ramp up of production to 175,000 barrels per day of condensate and 320 million standard cubic feet per day (mmscfd) gas plateau is expected to be reached during summer 2009.
Akpo will allow the commercialisation of significant quantities of gas, which are exported towards the Amenam hub, enhancing Total’s capacity to supply gas to the domestic market and to the NLNG liquefaction plant.

“This early start-up for Akpo demonstrates the dedication of the teams involved in delivering such a complex, yet technologically sound project”, declared Yves-Louis Darricarrère, President Exploration and Production. “This development will bring additional hydrocarbon resources whilst contributing to the development of local communities.”

TUPNI has a 24% interest alongside the OML 130 partners: NNPC (Nigerian National Petroleum Corporation), Sapetro (South Atlantic Petroleum) of Nigeria, CNOOC Ltd. of China and Petrobras of Brazil. The field, discovered in the year 2000, is located 200 kilometres from the Nigerian coastline in water depth ranging from 1,200 to 1,400 metres.

About the people involved
In Nigeria, as in all countries in which the Group operates, Total assumes its responsibility towards the local communities and the environment. Ensuring the safety of people who work on its sites, enhancing living conditions in host countries and reducing the impact of its activities on the environment are the key themes of the Group’s commitment to sustainable development.
The Akpo project, in which the Group displayed its expertise to ensure sustainable development of the country’s energy resources in the deep offshore, has generated more than 11 million manhours in Nigeria to date, which is a record, and will generate up to an overall total of 15 million manhours in Nigeria by the time it is complete.
About the technology involved
The field development requires 44 wells (22 producers, 20 water injectors and 2 gas injectors), out of which 22 have already been drilled. The subsea infrastructures, transporting the hydrocarbon effluents, consist of 110 kilometres of a complex array of high pressure-high temperature subsea flowlines connected by Steel Catenary Risers (SCR) pipe sections to a Floating Production Storage and Offloading vessel (FPSO). The 100,000 tons dry weight FPSO, maintained on location by 12 anchor lines, houses the surface treatment facilities and is designed to process 185,000 barrels per day and store up to 2 million barrels of stabilised liquid hydrocarbons. Those in turn are exported through a single point mooring oil terminal, located 2 kilometres away.
The design of Akpo complies with the Nigerian government’s “Flare out” regulation, and is in line with Total’s strategy of reducing flaring. Furthermore, in order to optimise gas utilisation, Akpo has been designed as a hybrid development capable of handling up to 530 mmscfd of high pressure gas out of which 185 will be re-injected into the reservoir to maximise hydrocarbon recovery and 320 will be exported by pipeline. This will make Akpo an essential contributor to Total’s growth strategy in the gas industry, enabling additional supply to the domestic market and to the NLNG gas liquefaction plant.
