The Nigerian Agip Oil Company (NAOC) says the gas leak on its facility in Bayelsa has been brought under control.
This is contained in statement by a Spokesman of the company, Domenica Spina.
The company stated that the line had been depressurised and iwas currently being repaired.
Agip said it was regrettable that the impact of the incident on gas output was significant.
"Eni confirms that a third party's interference hacksaw cut caused a gas leak at the Ogbainbiri-OB/OB gas pipeline," the company said.
Speaking on the development, Mr Idris Musa, the Director-General, National Oil Spills Detection and Response Agency (NOSDRA), said the agency would lead an investigation into the incident.
"We got the report of the incident in the early hours of Tuesday. We shall ensure a thorough investigation as soon as it is safe to do so.
"Our investigation will be transparent. We shall also make our findings public in due course," he said.
Supreme reports that a production data obtained from Agip shows that the leak may cut its gas export by five million standard cubic meters per day (MMSCM/d).
Supreme further reports that the gas pipeline suffered vandalism three times in April 2022.
