Oryx Petroleum Corp. Ltd., Calgary, is moving ahead on a third appraisal well at Zey Gawra field in the Kurdistan region of Iraq (OGJ Online, Nov. 11, 2013). The company said its third well will appraise both the Tertiary and Cretaceous reservoirs at Zey Gawra, but it will be completed as a second Cretaceous producer. The well will be spudded in the second quarter. This news followed Oryx’s December 2016 sidetrack of the Zey Gawra-1 (Zey Gawra-1ST)well.
The operator completed the sidetrack in open hole partially penetrating the Cretaceous reservoir. Production is currently constrained to 1,500 b/d of 35.5° gravity oil with GOR 3 Mcf/stock-tank bbl and less than 0.5% water, with more than 1,500 psi. Extended production testing continues, Oryx said.
The operator is hauling Zey Gawra’s production to the Hawler tanker terminal where is stored and blended with Demir Dagh crude oil before being exported through the Kurdistan Export Pipeline (OGJ Online, June 18, 2013; Aug. 7, 2013).
The Hawler license area averaged 3,100 b/d in fourth-quarter 2016. Production from the Demir Dagh-3 well ceased in late December due to an abrupt increase in the water-oil ratio, Oryx said. The well, which produced from the Jurassic reservoir, was expected to decline later this year. The company is surveying options for remediation but said the loss of production was offset by its Zey Gawra-1ST well.
