This has lifted crude oil production, which has been fluctuating between 2.1 million barrels per day and 2.3 million bpd since the beginning of the year.
Reuters cited a Shell spokesperson as saying the pipeline reopened on September 8.
Shell Petroleum Development Company of Nigeria Limited had shut in the TNP in July following a leak on the Bomu-Bonny section at Owokiri, which was found to be caused by a six-inch crude theft valve being placed on the line.
The implication of this development, SPDC had said, was that some 150,000 barrels of oil per day were being deferred from the closure of the crucial pipeline.
