Nigeria’s ANOH Gas Project Reaches First Gas, Begins Deliveries to Indorama

Nigeria’s ANOH gas project has reached first gas, with Seplat Energy beginning deliveries to Indorama as the facility ramps up toward 300 million standard cubic feet per day and prepares additional LNG offtake routes.

(P&GJ) — Seplat Energy said its ANOH gas project in Nigeria has achieved first gas, following completion of a dedicated export pipeline and receipt of regulatory approvals.

Gas supply began on Jan. 16, 2026, after the 6.8-mile (11-km) Indorama gas export pipeline was completed and approved by Nigeria’s upstream regulator. The ANOH Gas Processing Company (AGPC) has started delivering processed gas to the Indorama Petrochemical Plant under firm and interruptible gas sales agreements, according to the company.

Four upstream wells that had been on standby since November 2025 were brought online to enable initial gas flows. Since first gas, wet gas production has stabilized at roughly 40–52 million standard cubic feet per day, delivered directly from the ANOH gas plant to Indorama. Condensate output has reached approximately 2,000–2,500 barrels per day and is expected to increase as production ramps up.

Preparations are also underway to begin gas sales to Nigeria LNG under an interruptible offtake arrangement, which would support the project’s scale-up toward its full design capacity of 300 million standard cubic feet per day. Meanwhile, construction of the OB3 export pipeline—originally designated as the primary domestic evacuation route—has resumed under Nigeria’s gas infrastructure authority, with a revised completion timeline expected to be announced later.

The ANOH gas plant was developed by AGPC, a joint venture between Seplat Energy and the Nigerian Gas Infrastructure Company. The facility includes two 150- million standard cubic feet per day gas processing trains, LPG recovery units, condensate stabilization units, a 16-MW power plant and supporting infrastructure, and is designed to operate with zero routine flaring.

The project unlocks an estimated 4.6 trillion cubic feet (Tcf) of condensate-rich gas across the unitized OML 53 and OML 21 fields. Seplat’s net proved and probable gas reserves in the unitized area were estimated at 0.8 Tcf at year-end 2024. The company said it will generate revenue from both upstream wet gas sales and dividends tied to its 50% ownership stake in AGPC.

“ANOH is the first of the seven critical gas development projects identified by Federal Government of Nigeria to commence operations,” Roger Brown, Chief Executive Officer of Seplat Energy, said. “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 million standard cubic feet per day.”

Seplat said the ANOH gas plant was completed without a recordable lost-time incident across 17.5 million work hours.
