The Nigerian National Petroleum Company (NNPC) Limited and its partner, Heirs Energies, have successfully doubled natural gas production at a key oil block, OML 17, as part of a broader strategy to boost domestic supply and ease the country’s electricity shortages.
The increase comes from the OML 17 oil and gas field, operated by Heirs Energies in a joint venture with the Nigerian state oil company.
A “rigless well intervention” unlocked an additional 135 million standard cubic feet of gas per day (MMscf/d), enough to feed multiple power plants, directly contributing to an increase in electricity generation capacity by over 350MW.
Nigeria’s overall daily average gas production reached 7.59 billion standard cubic feet per day (Bscf/d) in July 2025, marking a sustained increase over recent years.
Heirs joined Western energy majors including Shell Plc, Chevron, TotalEnergies SE, and Seplat Energy Plc to have increase gas output in a bid to strengthen Nigeria’s electricity supply for industries and households.
Average daily electricity generation clocked in at 5,700 MW in the final quarter of 2025, an increase from 4,100 MW in Q4 2023.
Meanwhile, ongoing and completed infrastructure projects are set to further boost Nigeria’s domestic gas supply. The newly commissioned Assa North-Ohaji South (ANOH) gas plant, considered Nigeria’s largest, is expected to deliver up to 850 MMscf/d.
Other critical infrastructure projects, such as the Obiafu-Obrikom-Oben (OB3) gas pipeline, are part of the effort to expand the gas network and meet increasing domestic demand.
