Seplat Energy has confirmed that its jointly-developed $420 million Assa North–Ohaji South (ANOH) gas processing plant is on track to commence full operations in the second half of 2025.
The update was shared on the company’s official LinkedIn page and reviewed by Energy in Africa.
According to Seplat’s Chief Operating Officer, Samson Ezugworie, the company remains fully committed to the timely launch of the 300 million standard cubic feet per day (MMscfd) gas facility, a joint venture between Seplat and NNPC Limited.
“This is a top priority for the government, and we monitor progress continuously. The OB3 pipeline infrastructure is critical to the commencement of full operations at the ANOH Gas Plant,” said Ezugworie.
“We remain optimistic that full operations will begin in the latter half of 2025.”
The project, located in Ohaji, Imo State, achieved mechanical completion in December 2023 without recording any Lost Time Incident (LTI) over 11 million man-hours.
However, technical challenges have delayed the river-crossing segment of the OB3 line, with tunnelling work reaching just 1.12 km of the 1.85 km total distance.
The ongoing tunnelling is expected to be completed in Q2 2025.
Commissioned in March 2024, ANOH is one of Nigeria’s most ambitious greenfield gas projects, designed to support the country’s energy transition by supplying dry gas, condensate, and LPG to both domestic and international markets.
The ANOH plant is part of Seplat’s broader strategy to strengthen its gas business following the acquisition of ExxonMobil’s onshore and shallow-water assets in Nigeria.
Speaking during the company’s 12th Annual General Meeting (AGM) held in Lagos, Seplat Chairman Udoma Udo Udoma stressed gas as a cornerstone of Seplat’s future growth.
“Our gas division will grow rapidly with enormous resources offshore, as well as our well-established onshore gas business,” said Udoma.
Seplat earlier announced plans to invest up to $320 million in 2025 to develop new wells and infrastructure, including finalizing the ANOH project.
While the facility is ultimately designed to process up to 600 MMscfd, the current development phase targets 300 MMscfd.
