Chevron had to cut its crude oil production by 11,500 barrels per day after last weeks attack on its supply pipeline in southern Nigeria
Industry sources said the damaged pipeline supplies crude from the Makaraba, Otunana and Abiteye flow stations to Chevron's Escravos oil export terminal in the volatile Niger Delta.
Colonel Rabe Abubakar, spokesman for the military Joint Task Force protecting oil facilities and workers in the region said the attack was an act of sabotage.
In result, it led to the shut-in of 11,500 bpd from its Makaraba platform in Delta state.
Chevron, a major international oil operator in Nigeria, accounts for 320,000 barrels per day of crude.
But unrest in the Niger Delta has forced it to shut down some of its facilities.
