Seplat Energy Plc, a leading Nigerian independent energy company listed on both the Nigerian Exchange Limited and the London Stock Exchange, has announced that the 300 MMscfd ANOH gas project has achieved first gas, marking a major step in Nigeria’s gas development drive.
The company stated that following the completion of the 11km Indorama gas export pipeline and the receipt of regulatory approval from the Nigerian Upstream Petroleum Regulatory Commission NUPRC, ANOH Gas Processing Company AGPC commenced gas supply to Indorama on Friday, 16 January 2026, under firm and interruptible offtake Gas Sales Agreements GSAs. To enable the flow of gas, four upstream wells that had been on standby since November 2025 were brought online to support the initial phase of operations.
Since first gas was achieved, wet gas production at the facility has continued to stabilise, delivering between 40 and 52 MMscfd of processed gas directly from the ANOH gas plant to the Indorama Petrochemical Plant. Condensate production has reached between 2.0 and 2.5 kboepd and is expected to increase further as gas output rises and the plant ramps up toward its full design capacity.
In addition, preparations are underway to begin sales of processed gas to the Nigeria LNG NLNG, with the offtake agreement structured on an interruptible basis. This arrangement is expected to support the ANOH gas plant as it scales production towards its full design capacity of 300MMscfd. Meanwhile, construction of the OB3 pipeline export route by Nigerian Gas Infrastructure Company NGIC has resumed. The OB3 pipeline was originally designated as the primary channel for supplying ANOH gas to the domestic market, and a revised completion date will 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 consists of two 150 MMscfd gas processing units, Liquefied Petroleum Gas LPG recovery units, condensate stabilisation units, a 16MW power plant and other supporting facilities. The plant was built to operate with zero routine flaring, supporting Nigeria’s gas utilisation and environmental sustainability goals.
Across the unitised fields of OML 53 and OML 21, the ANOH gas plant unlocks an estimated 4.6 Tcf of condensate rich gas resources. Seplat’s working interest 2P reserves in the unitised field, as booked at year end 2024, stood at 0.8 Tcf. The company is expected to derive value from two income streams, including wet gas sales from OML 53 to the ANOH gas plant and dividends from its 50 percent equity ownership in AGPC.
The LPG produced from ANOH, combined with LPG output from Sapele and the Bonny River Terminal BRT, is expected to position Seplat as a leading supplier of clean cooking fuel to the domestic market. In addition, the ANOH gas plant will process flared gas from the Ohaji field, enabling Seplat to achieve its onshore End of Routine Flaring programme, a key commercial and sustainability initiative for the company.
The ANOH gas plant was developed without a single recordable Lost Time Incident LTI across 17.5 million man hours, reflecting the strong focus of the project team on safe and secure operations.
Roger Brown, Chief Executive Officer of Seplat Energy, said, “ANOH is the first of the seven critical gas development projects identified by Federal Government of Nigeria to commence operations. It is an important strategic project for Seplat, our partner NGIC, and Nigeria as a whole. It has taken a significant amount of commitment and hard work to complete the project in a part of the onshore Niger Delta with limited gas pipeline infrastructure, and we are extremely proud of this achievement. This is our third major gas processing facility onshore and increases our Joint Venture gross gas processing capacity onshore to over 850 MMscfd.”
He added, “ANOH will provide material income streams for Seplat, reduce our carbon intensity and contribute significantly to the 2030 production target of 200 kboepd, set at our recent CMD. It will also increase energy access for Nigerians in terms of both power and clean cooking fuel for the local communities, while advancing delivery of our mission to support economic prosperity in Nigeria.”
