Ofon Phase 2

Tapping as-yet undeveloped reserves safely and incorporating solutions for lasting environmental progress.




Nigeria’s Ofon field, on stream since 1997, is about 60 kilometers from Port Harcourt in 40 meters of water. The second phase of field development raises output from the current 30,000 barrels of oil equivalent per day (boe/d) to a total of 90,000 boe/d of oil, gas and condensate. Phase 2 sharply reduces Total’s greenhouse gas emissions by eliminating flaring during routine operations. We monetize the associated gas from the field, a major step forward for the environment. During the whole field development phase until the start in January 2015, we deployed an array of technical innovations and implemented our most extensive local content programs in the country to date.

Eliminating Gas Flaring

Ofon Phase 2 monetizes associated gas as an energy source and eliminates the flaring of 950,000 cubic meters per day during routine operations. It is a major step forward in terms of reducing greenhouse gas emissions on the project.

Consistent with applicable Nigerian legislation and regulations, this change of practice was put in place in December 2014 and represents an example of sound environmental stewardship.

Three million cubic meters per day of gas are piped over 70 kilometers to the Amenam offshore gas hub. From there, the gas is exported to the onshore Bonny LNG plant.

Three Uses for Associated Gas

  • Gas exported to the onshore Bonny LNG plant: 3,000,000 cubic meters per day.
  • Gas lift (injection into oil wells to enhance oil recovery): 800,000 cubic meters per day.
  • Gas for power generation to supply electricity to the Ofon facilities: 500,000 cubic meters per day.
