Total E&P Nigeria Limited said it has finally stopped the subsurface gas flow from the affected Ibewa 16 well.
In a statement on Sunday, the company said the snubbing intervention, which started on May 9, has been successful and has stopped the subsurface gas flow.
The snubbing operation consisted of introducing small pipes into the well to pump heavy fluids to stop the flow and set cement plugs to isolate the reservoir.
It said the cement seal of the well is now being finalised.
The statement added: “TEPNG will continue to monitor and perform analysis of air and water quality as well as engaging and providing updates to the representatives of the neighboring communities, State and Local Government, regulators and other stakeholders.”
