Genel reached agreement to acquire stakes in the Chevron operated Sarta block, in the Kurdistan Region of Iraq, in January 2019.
Genel acquired 30% equity in the Sarta licence by paying a 50% share of ongoing field development costs until a specific production target is reached, together with a success fee payable on achievement of a production milestone. Chevron retain a 50% interest in the Sarta licence and the Kurdistan Regional Government hold the remaining 20%.
Following completion of the farm-in in February 2019, the field partners have progressed the Phase 1A development towards first oil, which is on track for the summer of 2020.
Civil construction work at the Sarta field is continuing on schedule, and is now 60% complete, with flowlines laid and buried and the oil storage tanks nearing completion. Following recompletion of the Sarta-2 well and commissioning of the facility, Sarta-2 and Sarta-3 will be placed on production, both of which flowed c.7,500 bopd on test.
Phase 1A represents a low-cost pilot development of the Mus-Adaiyah reservoirs, designed to recover 2P gross reserves estimated by Genel at 34 MMbbls.
Genel estimates gross resources at Sarta to be c.500 MMbbls. This potential has now been validated through an external audit conducted by ERCE, who have estimated a mid-case total recoverable oil resource of 593 MMbbls, of which 264 MMbbls is classified as 2C resource.86 MMbbls of this 2C resource is assigned to the Mus-Adaiyah reservoir, giving a 2P/2C sum for the Mus-Adaiyah of 120 MMbbls.
ERCE’s summed prospective oil resource estimate across the four proven reservoir intervals at Sarta is 295 MMbbls. 133 MMbbls is assigned to the Butmah reservoir, directly underlying the Mus-Adaiyah and the same zone as the oil resource at Bina Bawi, of which it is geologically on trend. Taken as a whole, the Mus-Adaiyah-Butmah reservoirs at Sarta have a summed mid case total recoverable resource estimate of 253 MMbbls.
Conversion of these resources into reserves is a key objective of the three well campaign scheduled for 2021, and part of the phase 1A pilot development, with appraisal focused on the resource hosted in Jurassic reservoirs a secondary objective for the 2021 wells.
With first oil Sarta expected in 2020, preparations are already underway for this campaign. Construction work on the new well pads is due to start in H2 2020 and the field partners are investigating a range of options to fast-track oil production from these wells should they be successful.
