“The volume is more or less 2 million barrels. It is a mix of very light crude so the oil is a condensate grade,” one of the sources said.

“The loading date is open.”

The source said the oil would come from storage tanks rather than fresh output from oil fields.

A very limited number of oil companies have been invited.

The sources said the oil would be loaded from the western border of Libya. 

It was not clear who is selling it.

The country has exported just two cargoes of crude oil since the start of fighting between anti-Muammar Qaddafi forces and troops still loyal to the leader.

One was lifted by Vitol and delivered to Hawaii. The other was delivered to Sardinia, according to shipping data. One cargo, which was meant to be lifted by Italy’s Eni, failed.

Libya is one of the 12 members of the Organization of the Petroleum Exporting Countries and holder of Africa’s biggest oil reserves. 

Libya’s oil output, which was about 1.6 million barrels per day before the war, remains shut in.

In late-August, Abdeljalil Mayuf, spokesman for Arabian Gulf Oil Company (AGOCO) said operations at the eastern oilfields of Sarir and Mesla would start on Sept. 15 and that Tobruk could export by the end of the month.

Initial production will be around 60,000-100,000 bpd, he said.
