Peshkabir oil field is located in Kurdistan in the northern part of Iraq, within the Tawke production sharing contract (PSC), which also contains the Tawke field.
The field is jointly owned by DNO (75%, operator) and Genel Energy International (25%). Production at the field started through an early production system in 2017.
The Peshkabir and Tawke fields are jointly producing an average of 109,050 barrels of oil per day (bopd).
Peshkabir oil field location, discovery and reserves
The Peshkabir oil field is located in the western part of the Tawke PSC. Discovered in October 2016, it is a high amplitude anticline with shallow layers extending on the flanks of the structure.
The combined proven reserves of the Peshkabir and Tawke field are estimated to be 504 million barrels.
Exploration and appraisal at Peshkabir oil field
The appraisal activities of the Peshkabir oil field began with the drilling of the Peshkabir-2 well in October 2016. The well discovered oil in the Cretaceous horizon in the southern part of the field. A 170m column of the well was tested and flowed at the rate of 3,800bopd with an API of 28°.
The second appraisal well on the field, Peshkabir-3, was drilled in July 2017 and testing was completed in December 2017. A total of 11 zones in a 1.2km horizontal interval of the Cretaceous and Jurassic reservoir of the well were tested, out of which ten were oil and one was a gas zone.
The oil zones flowed at the rate of 5,340bopd on an average on a 64/64in choke.
The fourth appraisal well, Peshkabir-4, was drilled in 2018 to a depth of 3,525m to test the Triassic reservoir of the field. A total of 11 zones of the well were tested and flowed at the rate of 1,500-7,000bopd per zone.
“The Peshkabir oil field is located in the western part of the Tawke PSC.”
Peshkabir-5 well was drilled 7km west of Peshkabir-3 and was completed in June 2018. It successfully confirmed the western extension of the field. Testing of four zones of the well was completed in July 2018, which flowed at the rate of 4,000-7,500bopd per zone.
Two additional wells, Peshkabir-6 and Peshkabir-7, are currently being drilled. Peshkabir-6 will explore the field’s Triassic formation and prove the Cretaceous oil/water contact level of the field, while Peshkabir-7 is a high angle producer well being drilled between Peshkabir-4 and Peshkabir-5.
Production testing at the two wells is expected to commence in August 2018.
Peshkabir oil field development and production
The development of the Peshkabir oil field was accelerated by the company by bringing the field on production within six months of drilling the second appraisal well. The Peshkabir-2 and Peshkabir-3 wells were brought into production through an early production system in 2017 and reached a production rate of 16,000bopd by February 2018.
The third appraisal well, Peshkabir-4, was placed in production in July 2018 and started producing at the rate of 10,000bopd. Peshkabir-5 was also put on production in July 2018 at the rate of 8,000bopd.
The produced oil is transported through a pipeline to the Tawke export terminal located 12km away at Fish Khabur in the north eastern part of Kurdistan. It is co-mingled with the Tawke field production and exported through Turkey.
Future development activities at Tawke licence
DNO plans to drill four new wells in 2018 at the Tawke licence. The company is also undertaking engineering studies to increase the oil recovery at the field through the injection of gas recovered from Peshkabir.
The major focus in 2018 will be on rebuilding of the Tawke field reservoir models as well as workovers of existing wells.
