According to the latest Nigerian National Petroleum Corporation (NNPC) report about 25 million barrels of crude oil were shut-in at four production terminals within one month as a result of various challenges at the terminals, The Punch reports.

Specifically, the Forcados, Qua Iboe, Bonny and Bonga oil production terminals shut-in millions of crude in March 2017 due to challenges like force majeure, poor pipeline integrity, leaks or turn around maintenance.

Officials of the Nigerian National Petroleum Corporation (NNPC) said in Abuja on Monday that the challenges were the key inhibiting factors that dragged crude oil production performance in March and other months.

It had been reported earlier that the total volume of crude oil produced in Nigeria had been reducing since January this year, leading to a cumulative loss of about N131.8bn in less than three months.
