Nigerian National Petroleum Corporation (NNPC) and Heirs Energies have restored production at a gas facility that had been offline for more than a year, enabling the joint venture to double output and increase supplies to power producers struggling with fuel shortages.
The NNPC/Heirs Energies Joint Venture (JV) successfully utilized a rigless recompletion technique on a previously shut-in non-associated gas well within OML 17.
This pioneering technical intervention doubled the JV’s gas output to a peak of 135 million standard cubic feet per day.
Natural gas underpins most of Nigeria’s grid power, yet years of underinvestment, vandalism and unpaid bills have left plants chronically short of fuel, worsening blackouts and forcing reliance on costly diesel.
The restored OML 17 facility is already making a difference.
Transcorp’s Transafam Power has quadrupled output to more than 180 megawatts from an average of 50 megawatts a day, Heirs Energies said in a statement.
Electricity generation companies, including First Independent Power Ltd. and Geometric Power, have seen combined output surge to more than 350 megawatts from around 100 megawatts, it said.
This increased power generation is sufficient to supply hundreds of thousands of homes and businesses, leading to reduced blackouts and more stable power for critical infrastructure across the region.
Instead of an expensive new drill or conventional workover, Heirs Energies engineered a rigless through-tubing recompletion into an untapped reservoir interval.
This method was completed safely, in record time, and at just 15% of the cost of drilling a new well, setting a new standard for rigless solutions in Nigeria’s upstream sector.
