Seplat Energy Plc a leading Nigerian independent energy company listed on both the Nigerian Exchange Limited and London Stock Exchange, is pleased to announce that the 300 MMscfd ANOH gas project has achieved first gas.
Following completion of the 11km Indorama gas export pipeline and receipt of regulatory approval from the Nigerian Upstream Petroleum Regulatory Commission (NUPRC), ANOH Gas Processing Company (AGPC) commenced gas supply to Indorama, under a firm and interruptible offtake Gas Sales Agreements (GSAs). To enable the flow of gas, the four upstream wells, which had been on standby since November 2025, were brought online.
Since first gas, wet gas production has been stabilizing, 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.
In addition, 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. 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.
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.
