C 137 Block is located in the western part of Libyan offshore zone, extending up to about 100 km from the coast, along with the Tunisian border. The license originates from a first contract awarded to AQUITAINE LIBYE in 1968. After various relinquishments, it is now divided into 2 zones, North and South, totalling 3184 km2. It is ruled under the amended EPSA 74, ratified by Libyan authorities on 12th April 1997 and valid until 11th April 2017 (plus 5 years in case of production extension).
