Marathon Oil discovered “multiple” stacked oil and natural gas producing zones at the Harir Block in the Kurdistan Region of Iraq Tuesday.
The Jisik-1 well was drilled to a total depth of 15,000 feet and is located about 40 miles northeast of Erbil.
Oil and natural gas shows were found over an “extensive” gross interval of both Jurassic and Triassic reservoirs, Marathon said.
A drill-stem testing program yielded a sustained flow rate of 6,100 barrels per day of oil.
Multiple non-associated gas zones also flowed at a combined rate of 10 to 15 million cubic feet per day without stimulation, along with associated condensate.
The gas and condensate flows were equipment restrained.
Jisik-1 will be suspended for potential future use as a producing well.
Houston-based Marathon Oil is the operator of the Harir Block, with a 45 percent working interest.
France’s Total holds a 35 percent working interest and the Kurdistan Regional Government holds a 20 percent carried interest.
