Production from the Messla and Sarir oil fields in south-east Libya could be shut down in less than four weeks if a blockade of the Marsa al Hariga port continues.
Output from the fields has been cut to less the half due to a dispute between the rival administrations over the right to export oil from the port.
Mustafa Sanalla (pictured), Chairman of the Tripoli-based National Oil Corporation (NOC) urged those preventing exports to reconsider their approach. "The worst thing is this blockade will achieve nothing ... In terms of legitimacy, which is what the blockaders want, it is a dead end," he said.
