Most international oil companies working in Iraq, along with the semi-autonomous region of Kurdistan, have agreed to cut crude output to fulfill an OPEC accord.
Libya's National Oil Corporation (NOC) said that pipelines leading from the western fields of Sharara and El Feel had been reopened after a two-year blockade, paving the way for a major boost to production.
The head of Russian oil company Lukoil, Vagit Alekperov, said that the firm has not received any directives from the Iraqi government in Baghdad to curb oil production for 2017.
Oman and Russia have been named to the committee set up by OPEC to oversee the implementation of oil production cuts agreed upon by OPEC and non-OPEC nations.
OPEC will be meeting non-OPEC countries in Vienna to finalize a global oil production cut agreement early December, while the group's oil output set another record high in November.
Crude oil prices steadied around $50 a barrel, holding onto big gains made after the Organization of Petroleum Exporting Countries (OPEC) and Russia agreed to restrict production.
