Seplat Energy Plc has announced the achievement of first gas from its 300 million standard cubic feet per day (MMscfd) ANOH gas project, marking a major milestone in Nigeria’s gas development drive.
The milestone follows the completion of the 11-kilometre Indorama gas export pipeline and the receipt of regulatory approval from the Nigerian Upstream Petroleum Regulatory Commission (NUPRC). Consequently, ANOH Gas Processing Company (AGPC) has commenced gas deliveries to Indorama Petrochemical Company 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, supplied directly from the ANOH gas plant to the Indorama Petrochemical Plant. Condensate output currently averages 2.0–2.5 thousand barrels of oil equivalent per day (kboepd) and is expected to rise as the facility ramps up towards its full design capacity.
AGPC is also preparing to commence processed gas sales to Nigeria LNG (NLNG) under an interruptible offtake arrangement. This is expected to further support the scaling up of production towards the plant’s 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 domestic gas supply, has resumed, with a revised completion timeline to be announced 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 units, Liquefied Petroleum Gas (LPG) recovery units, condensate stabilisation units, a 16MW power plant and other supporting infrastructure. The plant has been designed to operate with zero routine flaring.
Located across the unitised OML 53 and OML 21 fields, the ANOH development unlocks an estimated 4.6 trillion cubic feet (Tcf) of condensate-rich gas resources. Seplat’s net 2P reserves in the unitised field stood at 0.8 Tcf as at year-end 2024. The company will benefit from two key revenue streams: wet gas sales from OML 53 to the ANOH gas plant, and dividends from its 50 per cent equity interest in AGPC.
LPG production from ANOH, combined with output from Seplat’s Sapele facility and the Bonny River Terminal (BRT), is expected to position the company as a leading supplier of clean cooking fuel to Nigeria’s domestic market. In addition, the ANOH gas plant will process previously flared gas from the Ohaji field, supporting Seplat’s onshore End of Routine Flaring programme and reinforcing its sustainability objectives.
Notably, the project was delivered without a single recordable Lost Time Incident (LTI) across 17.5 million man-hours, underscoring a strong commitment to safety and operational excellence.
Commenting on the achievement, Seplat Energy Chief Executive Officer, Roger Brown, said ANOH is the first of seven critical gas projects identified by the Federal Government of Nigeria to reach operational stage.
“ANOH is a strategically important project for Seplat, our partner NGIC and Nigeria as a whole. Delivering this project in an area of the onshore Niger Delta 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 represents Seplat’s third major onshore gas processing facility and increases the company’s joint venture gross onshore gas processing capacity to over 850 MMscfd.
“ANOH will generate material income streams for Seplat, lower our carbon intensity and contribute significantly to our 2030 production target of 200 kboepd. It will also expand energy access through power generation and clean cooking fuel, while advancing our mission to support Nigeria’s economic prosperity,” Brown said.
