LONDON, July 20 (Reuters) - Libya's National Oil Corporation confirmed on Saturday that production at its 290,000 barrels per day El Sharara oilfield was currently offline.
NOC said it was conducting a full-scale investigation into suspected closed valves in the Hamada area.
It also said in a statement that production from El Feel oilfield was unaffected by the incident.
Sources earlier told Reuters that production at El Sharara had halted on Friday due to a valve closure on the pipeline linking the field to Zawiya. nD5N23U047 (Reporting By Ahmed Ghaddar Writing By Maha El Dahan Editing by Gareth Jones)
