The tribesmen calling themselves the Fezzan Anger Movement were protesting to demand more development help for their community. Fezzan is the historic name of the southern region of Libya where El Sharara oilfield is located.
"We as the force securing the field inform you that the Fezzan Anger Movement entered the field and stopped the production in line with the demands of the movement," the local oil force guarding the facility said in a statement.
The group of tribesmen also said they had shut the field.
The field, which usually pumps about 300,000 barrels per day, has been repeatedly threatened by tribesmen asking for better health and other state services for poor, desert region.
