Two workers, one a foreigner, were abducted during an attack by an unknown group at a facility at Libya’s giant Sharara oil field, engineers said.
The attack happened at a control station on the outskirts of Sharara, about 40 km from the main part of the field, an engineer said.
It was not immediately clear if the attack would impact production at the field, where output in recent months has been around 300,000 barrels per day (bpd).
Libya’s National Oil Corporation (NOC) operates Sharara in partnership with Repsol, Total, OMV and Equinor, formerly Statoil.
The field, in Libya’s remote south-west, suffered security problems in the past including theft of vehicles and mobile phones.
The facility targeted on Saturday is Station 186 and was attacked last year.
In addition to being one of Libya’s main export grades of oil, Sharara feeds the 120,000 bpd Zawiya oil refinery on the north-west coast.
