Marathon Oil KDV—a wholly owned subsidiary of Marathon Oil—discovered multiple stacked oil- and gas-producing zones at its Jisk-1 exploration well in the Harir block of Iraq’s Kurdistan region. The well reached a total depth of 15,000 ft and encountered Jurassic and Triassic reservoirs. Drillstem testing yielded 6,100 B/D of oil and nonassociated gas flowing at a rate of 10–15 MMcf/D. The well was cased and suspended as a potential producer. Marathon (45%) operates the block with partners Total (35%) and the Kurdistan Regional Government (20%).
