300 MMscfd ANOH Gas project achieved first gas — Seplat

Seplat Energy Plc has announced that the 300 MMscfd ANOH gas project has achieved first gas.

According to a statement by the company, ANOH Gas Processing Company (AGPC) commenced supply to Indorama under a firm and interruptible offtake Gas Sales Agreements (GSAs) following the completion of the 11km Indorama export pipeline and receipt of regulatory approval from the Nigerian Upstream Petroleum Regulatory Commission (NUPRC) last Friday.

To enable the flow of gas, according to the statement, four upstream wells, which had been on standby since November 2025, were brought online.

“Since first gas, wet gas production has been stabilising, delivering 40-52 MMscfd of processed gas directly from the ANOH gas plant to the Indorama Petrochemical Plant.

 “Condensate production has reached 2.0-2.5 kboepd and is expected to increase with gas production as the plant ramps up to design capacity,” the statement read.

In addition,  Seplat disclosed that preparations are underway to initiate sales of processed gas to the Nigeria LNG (NLNG) with an offtake agreement structured on an interruptible basis and will support the gas plant to further scale production towards full design capacity of 300MMscfd.

Commenting on the feat, Chief Executive Officer of Seplat Energy,  Roger Brown, said: “ANOH is the first of the seven critical gas development projects identified by Federal Government of Nigeria to commence operations.

He described it as “an important strategic project for Seplat, our partner NGIC, and Nigeria as a whole.”

He said the feat 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.

“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.

“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,” he said.

Meanwhile, the construction of the OB3 pipeline export route by Nigerian Gas Infrastructure Company (NGIC), originally designated as the primary channel for ANOH gas supply to the domestic market, has resumed and a revised completion date will be communicated in due course, according to the statement by Seplat

The ANOH gas plant was developed by AGPC, an incorporated joint venture between Seplat Energy and the NGIC. The integrated plant consists of two 150 MMscfd gas processing units, Liquefied Petroleum Gas (LPG) recovery units, condensate stabilization units, a 16MW power plant and other supporting facilities, and has been built to operate with zero routine flares.

 “Across the unitised field of OML 53 and OML 21, the ANOH gas plant unlocks an estimated 4.6 Tcf condensate-rich gas resource base. Seplat’s working interest 2P reserves in the unitised field, as booked at year end 2024, stood at 0.8 Tcf.  Seplat will derive value from two distinct income streams: wet gas sales from OML 53 to the ANOH gas plant, and dividends from its 50% equity ownership in AGPC.

“The LPG produced from ANOH, combined with the LPG production at Sapele and the Bonny River Terminal (BRT), will make Seplat a leading supplier of clean cooking fuel to the domestic market. In addition, the ANOH gas plant will process the 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 statement read.

The ANOH gas plant has been developed without a single recordable Lost Time Incident (LTI) across 17.5 million man-hours, a testament to the focus of the whole team on safe and secure operations.
