Seplat Energy Plc, a Nigerian independent energy company, says the 300 MMcfd Assa North–Ohaji South gas project has achieved its first gas.
The company disclosed this in a corporate disclosure signed by Eleanor Adaralegbe, Seplat Energy’s chief financial officer, and filed with the Nigerian Exchange Ltd. on Tuesday.
Mr Adaralegbe said this followed the completion of the 11km Indorama gas export pipeline and the receipt of regulatory approval from the Nigerian Upstream Petroleum Regulatory Commission on Friday, January 16.
He explained that gas supply was delivered under firm and interruptible gas sales agreements through the ANOH Gas Processing Company.
“According to him, four upstream wells that had been on standby since November 2025 were brought online to enable gas flow.
Mr Adaralegbe said that since the first gas, wet gas production had stabilised at between 40 and 52 MMscfd, delivered directly from the ANOH gas plant to Indorama.
He explained that condensate production had reached 2,000-2,500 barrels of oil equivalent per day and was expected to rise as production ramps up to full capacity.
Mr Adaralegbe noted that preparations were ongoing to commence processed gas sales to Nigeria LNG under an interruptible offtake arrangement, which would further support scaling production towards the plant’s design capacity of 300 MMscfd.
He also disclosed that construction of the OB3 pipeline export route by the Nigerian Gas Infrastructure Company, designated as the primary domestic gas evacuation route for ANOH, had resumed, with a revised completion date to be announced later.
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-megawatt power plant and supporting infrastructure, and is designed to operate with zero routine flaring.
The chief financial officer said the ANOH project unlocks an estimated 4.6 trillion cubic feet of condensate-rich gas across the unitised OML 53 and OML 21 fields.
He noted that its 2P reserves working interest in the unitised field stood at 0.8 trillion cubic feet as of the end of 2024.
Mr Adaralegbe said it would generate revenue from wet gas sales to the ANOH plant and dividends from its 50 per cent equity stake in AGPC.
He said that LPG output from ANOH, combined with production from its Sapele and Bonny River Terminal facilities, would position Seplat as a leading supplier of clean cooking fuel to the domestic market.
According to him, the plant would process previously flared gas from the Ohaji field, supporting its onshore End of Routine Flaring programme.
He noted that the ANOH gas plant was developed without any recordable Lost Time Incident, covering 17.5 million man-hours.
Roger Brown, chief executive officer of Seplat Energy, said, “ANOH is the first of the seven critical gas development projects identified by the 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.”
Mr Brown added, “This is our third major gas processing facility onshore and increases our Joint Venture gross gas processing capacity onshore to over 850 MMscf/d.
“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.”
