According to Reuters, U.S. energy firm Chevron has suspended production from an oil pipeline in Nigeria''s Delta state, which was breached on Friday. Chevron said it was investigating the damage to the Dibi-Abiteye pipeline, which feeds the Escravos oil stream, but did not comment on how much production would be lost. Escravos crude exports were due to be around 123,000 barrels per day in December, according to loading programmes. It was not clear how much this would be reduced by the pipeline damage. The Niger Delta Liberation Force (NDLF), a militant faction in Nigeria''s oil-producing wetlands region, said on Saturday it was behind the attacks on oil facilities operated by Chevron and Italian oil company Eni. The sabotage attacks followed raids earlier this month by a military task force comprising the army, navy and air force on camps believed to belong to John Togo, the suspected leader of the NDLF.
