WesternZagros Resources completed a workover of its Sarqala-1 well in Kurdistan Friday, doubling the well’s flow rate to 11,500 barrels per day.
During the workover the company installed larger tubing to replace the subsurface safety valve and increase the flow capacity of the well.
The well tested at rates of up to 11,500 barrels per day of 40 degree API oil from the Jeribe/Upper Dhiban reservoir, up from the previous average flow rate of 5,000 barrels per day.
The new flow rate of was reached after two days of flowing and stabilizing the well at progressively bigger choke sizes prior to the final flow.
The final flow rate was achieved on a one inch choke with a wellhead pressure of 2,155 pounds per square inch.
No stimulation was applied to the reservoir although it remains an option to do so at a later date.
As during the previous extended well test of Sarqala-1, the current test produced no hydrogen sulphide gas or formation water.
Following the completion of the post-workover test at Sarqala-1 WesternZagros plans to move the workover rig to the Hasira-1 well to start testing a light oil discovery in the Mio-Oligocene reservoir.
Sarqala-1 is located in the Garmian block in the southern region of Kurdistan.
Calgary-based WesternZargos operates and holds a 40 percent working interest in the Garmian block. Russia’s Gazprom holds a 40 percent interest and the Kurdistan Regional Government holds a 20 percent interest.
