(Bloomberg) -- Libya’s largest oil field halted production after protesters entered the facility, according to a person with direct knowledge of the operations. The field was pumping roughly 270,000 barrels a day on Tuesday before the protests began. Continuing agitation will result in “a tumbling of exports, in addition to shaking the confidence of foreign partners and impeding efforts to stabilize production,” according to the NOC letter. OPEC member Libya kept production stable at around 1.2 million barrels a day for most of the last year. Most Read from Bloomberg Businessweek©2024 Bloomberg L.P.
