Germany’s Winteshall Dea has transferred operatorship of some of its Libyan oilfields in the onshore Sirte basin to a state-led joint venture.

The German company holds interests in and operates Contract Areas 91 (former Concession 96) and 107 (former Concession 97) via Wintershall Aktiengesellschaft (WIAG), a joint venture with Russia’s Gazprom.

Operatorship will now be passed on to Sarir Oil Operations, a newly established joint operating company with the National Oil Corporation (NOC).
