The Sheikh Adi-2 exploration well, which is situated 1.45km north of Sheikh Adi-1 exploration well, was drilled to a total depth of 2,754m and tested four reservoir zones.

The four reservoir zones were tested at measured depth between 1,420m and 1,700m with an aggregate flow rate of 4,235 barrels of oil per day across the Upper Butmah, Adaiyah, Mus and Sargelu formations in the Jurassic.

Gulf Keystone executive chairman and CEO Todd F Kozel said, "This most recent exploration success points to the significant potential for further growth and future synergies across our world-class acreage in the Kurdistan Region of Iraq."

With 80% interest in the block, Gulf Keystone is the operator and has communicated the Sheikh Adi Block Management Committee, about the discovery made on the block, which is situated west to the company’s major commercial discovery Shaikan Block.

The provisional results indicate that the oil gravity of the new discovery is similar to that of the Shaikan Blocks.
