January 28, 2026 [Storage Terminals Magazine]- 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.

Following the completion of the 11 km Indorama gas export pipeline and the receipt of regulatory approval from the Nigerian Upstream Petroleum Regulatory Commission, ANOH Gas Processing Company commenced gas deliveries to Indorama on Friday 16th January 2026. Supplies are being delivered under firm and interruptible gas sales agreements. To enable the start of gas flow, four upstream wells, which had been on standby since November 2025, were brought into production.

Since first gas was achieved, wet gas production has been stabilising, with processed gas deliveries of between 40 and 52 MMscfd supplied 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 throughput ramps up towards the plant’s design capacity.

Preparations are also underway to commence sales of processed gas to Nigeria LNG. The offtake agreement is structured on an interruptible basis and is expected to support the continued scaling of production towards the plant’s full design capacity of 300 MMscfd. Meanwhile, construction of the OB3 pipeline export route by the Nigerian Gas Infrastructure Company, originally designated as the primary route for supplying ANOH gas to the domestic market, has resumed, with a revised completion timeline 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 recovery units, condensate stabilisation units, a 16 MW power plant and supporting infrastructure, and has been designed 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 Tcf of condensate-rich gas resources. Seplat’s working interest 2P reserves in the unitised field stood at 0.8 Tcf at the end of 2024. The company is expected to benefit from two revenue streams: wet gas sales from OML 53 to the ANOH gas plant, and dividends derived from its 50 percent equity interest in AGPC.

LPG production from ANOH, combined with output from Seplat’s Sapele and Bonny River Terminal facilities, 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, a key commercial and sustainability initiative.

The ANOH gas plant was delivered without a single recordable lost time incident over 17.5 million man-hours worked, reflecting a strong focus on safety and operational discipline throughout the project.

Roger Brown, Chief Executive Officer of Seplat Energy, said the ANOH development is the first of seven critical gas projects identified by the Federal Government of Nigeria to enter operations. He described it as a strategically important project for Seplat, its partner NGIC and the country as a whole, noting the challenges of delivering major gas infrastructure in the onshore Niger Delta. He added that the project represents Seplat’s third major onshore gas processing facility, increasing joint venture gross onshore gas processing capacity to more than 850 MMscfd.

Brown also highlighted that ANOH is expected to deliver material income streams for Seplat, reduce carbon intensity and make a significant contribution towards the company’s 2030 production target of 200 kboepd. He noted that the project will also enhance energy access through increased power generation and the supply of clean cooking fuels, while supporting broader economic development in Nigeria.
