Seplat Energy Plc has announced the achievement of first gas from its 300 million standard cubic feet per day (MMcfd) ANOH gas project following the completion of the 11-kilometre Indorama gas export pipeline and the receipt of regulatory approval from the Nigerian Upstream Petroleum Regulatory Commission (NUPRC).
On Friday, January 16, 2026, the ANOH Gas Processing Company (AGPC) commenced gas supply 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 online. Since the first gas, wet gas production has stabilised, delivering between 40 and 52 million standard cubic feet per day (MMscfd) of processed gas directly from the ANOH gas plant to the Indorama Petrochemical Plant.
Condensate production has reached between 2,000 and 2,500 barrels of oil equivalent per day (kboepd) and is expected to rise further as the plant ramps up towards its full design capacity.
Preparations are also underway to initiate gas sales to Nigeria LNG (NLNG) under an interruptible offtake agreement, which is expected to support further scaling of production towards the plant’s full 300MMcfd capacity. Meanwhile, construction of the OB3 pipeline export route by the Nigerian Gas Infrastructure Company (NGIC), originally designated as the primary domestic evacuation route for ANOH gas, has resumed, with a revised completion date to be announced in due course.
ANOH Gas Plant
The ANOH gas plant was developed by AGPC, an incorporated joint venture between Seplat Energy and NGIC. The integrated facility comprises two 150MMcfd gas processing units, liquefied petroleum gas (LPG) recovery units, condensate stabilisation units, a 16-megawatt power plant and supporting infrastructure. The plant has been designed to operate with zero routine flaring.
Covering the unitised OML 53 and OML 21 fields, the ANOH gas project 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 at year-end 2024. The company is expected to benefit from two income streams: wet gas sales from OML 53 to the ANOH gas plant and dividends from its 50 per cent equity ownership in AGPC.
LPG output from ANOH, combined with production from Seplat’s Sapele and Bonny River Terminal facilities, is expected to position the company as a leading domestic supplier of clean cooking fuel. In addition, the ANOH plant will process previously flared gas from the Ohaji field, supporting Seplat’s onshore End of Routine Flaring programme.
Commenting on the milestone, Seplat Energy Chief Executive Officer, Roger Brown, said ANOH is the first of seven critical gas development projects identified by the Federal Government of Nigeria to commence operations.
“ANOH is an important strategic project for Seplat, our partner NGIC and Nigeria as a whole. Completing this project in an area of the onshore Niger Delta with limited gas infrastructure required significant commitment and teamwork, and we are extremely proud of this achievement,” Brown said.
He added that the project increases Seplat’s joint venture gross onshore gas processing capacity to over 850MMscf per day and will provide material income streams, reduce carbon intensity and support the company’s target of reaching 200,000 barrels of oil equivalent per day by 2030.
“Beyond the commercial value, ANOH will expand access to power and clean cooking fuel, support local communities and advance our mission to drive sustainable economic prosperity in Nigeria,” he said.
