The federal government has repaired a key pipeline connecting Chevron's Escravos oil and gas fields to two domestic refineries, a senior industry official said on Friday.
"The pipeline leading to the plant has been repaired. They began hydro testing a couple of days ago. The plant should be back online in a day or two," David Ige, group general manager at state-run NNPC told Reuters on the sidelines of an industry event in Barcelona.

A second NNPC source said the two refineries, Warri's 125,000 barrel per day facility and Kaduna's 110,000 bpd plant, could soon resume operations after tests are completed at the Chanomi Creek pipeline.
A lull in violence in the oil-producing Niger Delta has enabled workers to begin repairs on the pipeline, which has been attacked by militants in the past.
Nigeria's four state-owned refineries have a nameplate capacity of 445,000 bpd but have never operated at that level. Even if Nigeria's refineries are able to operate at full capacity, they would produce only a fraction of the needs of Africa's most populous country of 140 million people.
Refinery outages caused mainly by mismanagement and sabotage have forced the OPEC member to depend on massive fuel imports for its domestic needs.
