Seplat Energy on Tuesday announced the achievement of first gas from its 300 million standard cubic feet per day (MMscfd) Assa North–Ohaji South (ANOH) Gas Project, marking a major milestone in Nigeria’s gas development drive and paving the way for gas supply to Nigeria LNG Limited (NLNG).
Following the completion of the 11-kilometre Indorama gas export pipeline and receipt of regulatory approval from the Nigerian Upstream Petroleum Regulatory Commission (NUPRC), ANOH Gas Processing Company (AGPC) commenced gas supply to Indorama Petrochemical Plant on Friday, January 16, 2026, under firm and interruptible Gas Sales Agreements (GSAs).
To enable gas flow, four upstream wells that had been on standby since November 2025 were brought on stream. Since first gas, wet gas production has stabilised at between 40 and 52 MMscfd of processed gas delivered directly from the ANOH gas plant to Indorama. Condensate production has also reached 2.0–2.5 thousand barrels of oil equivalent per day (kboepd) and is expected to rise as the plant ramps up towards its full design capacity.
In addition, Seplat disclosed that preparations are underway to commence sales of processed gas to NLNG.
The offtake agreement with NLNG is structured on an interruptible basis and is expected to support the ANOH gas plant in scaling up production towards its full capacity of 300 MMscfd.
Meanwhile, construction of the OB3 pipeline export route by the Nigerian Gas Infrastructure Company (NGIC), originally designated as the primary evacuation route for ANOH gas to the domestic market, has resumed, with a revised completion date to be communicated in due course.
The ANOH gas plant was developed by AGPC, an incorporated joint venture between Seplat Energy and NGIC. The integrated facility comprises two 150 MMscfd gas processing trains, Liquefied Petroleum Gas (LPG) recovery units, condensate stabilisation units, a 16-megawatt power plant and other supporting infrastructure.
The plant was built to operate with zero routine flaring.
Located across the unitised OML 53 and OML 21 fields, the ANOH gas plant unlocks an estimated 4.6 trillion cubic feet (Tcf) of condensate-rich gas resources.
Seplat’s working interest 2P reserves in the unitised field stood at 0.8 Tcf as of year-end 2024.
The company is expected to generate value through wet gas sales from OML 53 to the ANOH plant and dividends from its 50 per cent equity stake in AGPC.
Seplat noted that LPG produced from ANOH, combined with output from its Sapele and Bonny River Terminal facilities, will position the company as a leading supplier of clean cooking fuel to Nigeria’s domestic market.
The ANOH plant will also process previously flared gas from the Ohaji field, supporting Seplat’s End of Routine Flaring programme and reinforcing its sustainability objectives.
The company further revealed that the ANOH gas plant was developed without a single recordable Lost Time Incident (LTI) across 17.5 million man-hours, underscoring a strong safety culture throughout the project execution.
Commenting on the milestone, Seplat Energy Chief Executive Officer, Mr. Roger Brown, described ANOH as the first of the seven critical gas development projects identified by the Federal Government to commence operations.
“ANOH is an important strategic project for Seplat, our partner NGIC and Nigeria as a whole. Completing this project in an onshore Niger Delta environment with limited gas pipeline infrastructure required significant commitment and hard work, and we are extremely proud of this achievement,” Brown said.
He added that the project is Seplat’s third major onshore gas processing facility, increasing joint venture gross gas processing capacity to over 850 MMscfd. According to him, ANOH will deliver material income streams, reduce carbon intensity, contribute to the company’s 2030 production target of 200,000 barrels of oil equivalent per day, and improve energy access through power generation and clean cooking fuel, while supporting economic growth in Nigeria.
