Bonga Field

The other partners in the field development are Exxon (20%), Nigerian AGIP (12.5%) and Elf Petroleum Nigeria Limited (12.5%) Located 120 kilometres (75 mi) southwest of the Niger Delta, the first discovery well was spudded in September 1995 after acquiring extensive information about the block via a 3D seismic survey in 1993/94.

The SURF (Subsea, Umbilicals, Risers, Flowlines) contract was won by Stolt Offshore (later renamed Acergy and now Subsea7).

Stolt vessel POLARIS installed all the flowlines and subsea structures in J-Lay and S-Lay pipelay modes.

Oil produced from the field is stored on the FPSO for transport to markets via tankers while the gas is exported via a pipeline to the Nigerian Coast for LNG.

Oil spills have the potential to cause great damage to the environment, for example water pollution, which reduces fishing yields and agriculture, which is one of Nigeria's largest industries.
