Seplat Energy Plc has successfully brought its Assa North–Ohaji South (ANOH) gas processing facility on stream, marking the first production of gas from the 300 million standard cubic feet per day (MMscfd) plant in Imo State. The company announced this milestone in regulatory filings to the Nigerian Exchange and the London Stock Exchange on January 20, 2026.
After completing an 11-kilometer export pipeline to Indorama and securing approval from the Nigerian Upstream Petroleum Regulatory Commission on January 16, 2026, gas supply began under a combined firm and interruptible sales agreement. Four upstream wells, which had been on standby since November 2025, were brought online to enable initial flow.
Since the startup, wet gas production has stabilized at 40–52 MMscfd, delivered directly to Indorama’s petrochemical plant in Rivers State. Condensate output stands at 2.0–2.5 thousand barrels of oil equivalent per day (kboepd), with further ramp-up expected toward full capacity.
Roger Brown, Seplat Energy’s Chief Executive Officer, called it a landmark achievement: “ANOH is the first of the seven critical gas development projects identified by the Federal Government of Nigeria to commence operations.

It is a crucial strategic project for Seplat, our partner, Nigerian Gas Infrastructure Company Limited (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 accomplishment.”
Operated by the ANOH Gas Processing Company (AGPC)—a 2019 joint venture between Seplat and NGIC—ANOH is Seplat’s third major onshore gas plant, boosting the JV’s total gross processing capacity to over 850 MMscfd. The facility features two 150 MMscfd trains, condensate stabilization, LPG recovery, and a 16 MW power plant. It draws gas from OML 53 and OML 21 unitized fields, where Seplat’s 2P reserves interest was 0.8 trillion cubic feet at the end of 2024.
Designed for zero routine flaring, the project supports Nigeria’s sustainability goals, Seplat’s flaring reduction program, and lower carbon intensity. It will generate revenue from wet gas sales and Seplat’s 50% AGPC stake, while improving domestic energy access through power and cleaner fuels. Interruptible sales to Nigeria LNG (NLNG) are advancing, with future OB3 pipeline integration promising broader market access.
Overall, ANOH reinforces Seplat’s gas monetization strategy, aids Nigeria’s gas resource utilization, and supports the company’s 2030 target of 200 kboepd production.
