Five zones due appraisal at Iraq's Pulkhana oil field

By OGJ editors

ShaMaran Petroleum Corp., Vancouver, BC, reported completing a reentry well that it expects to become the first well for tie-in to the Pulkhana early production facility planned for start-up in 2012 in Iraq Kurdistan.

Pulkhana-8 averaged 2,650 b/d of 31.6° gravity oil from the Upper Cretaceous Shiranish formation. Rates of as much as 3,530 b/d were recorded during the test.

The well continued to clean up during the test and produced an average of 24.6% muddy water which is believed to be drilling fluids and lost circulation material associated with the initial drilling of the well in 2006. To facilitate clean-up, the company is drilling 50 m of additional reservoir section.

Results from the reentry and from the Pulkhana-9 well have indicated that the Pulkhana structure could have as many as five oil-bearing reservoirs. Oil has been tested from the proven Euphrates and Shiranish formations, and the Jaddala, Upper Dhiban, and the Balambo are pending further evaluation as the appraisal program continues.

ShaMaran will sidetrack PLK-9 and barefoot test the Shiranish and Balambo intervals. The next appraisal well, Pulkhana-10, will appraise the Euphrates and Jaddala reservoirs. ShaMaran operates the Pulkhana block with 60% interest.
