As of 1 May 2019, a Supreme Decree was issued making official the award of Talara Basin Offshore Block Z-64 to Tullow Peru. The award was made possible after a citizen participation agreement was inserted in the verbiage of the original contract negotiated with PeruPetro and Tullow Peru which originally included five offshore blocks. The remaining four blocks remain under negotiations around a citizen participation agreement.  Local press reports indicated that Block 64 was expedited in the process due to its location near the offshore Karoon Gas Australia Block Z-38 in which Tullow has been approved for a farm-in participation of 35% working interest. The premise is that with an exploration well planned next year in Block Z-38 a rig would be available to drill in the neighboring Block Z-64 which has a considerable amount of information readily available to make geological evaluation of prospects in a shorter timeframe allowing the rig to stay in the region for multiple wells.  The 543.27 sq km block is in a water depth of between 75 m and 250 m with 362.65 sq km being located on the shelf and the remaining 180.62 sq km being located in deep water.
Supreme decree published in offical gazette for award of Z-64 toTullow (100%), four other blocks expected to follow eventually.
