Gulf Keystone has issued an update on its ongoing exploration and appraisal programme in the Kurdistan Region of Iraq, which includes the Shaikan block, a major discovery with independently audited gross oil-in-place volumes of between 8 billion barrels to 13.4 billion barrels calculated on the P90 to P10 basis with a mean value of 10.5 billion barrels.
Shaikan-4 Appraisal Well
The well testing programme for the Shaikan-4 appraisal well, drilled 6 km to the west of the Shaikan-1 discovery well, is ongoing with two well tests in the Triassic having been completed to date. Five further tests are planned in the Jurassic and Triassic.
In the course of the first well test conducted in the Kurre Chine C formation, Shaikan-4 achieved a flow rate of 563 barrels of oil per day (bopd) and 3.65 mmscf/d of gas at a 328 psi flowing wellhead pressure.
In the course of the second well test, Shaikan-4 tested a thin zone at the bottom of the Kurre Chine B formation achieving a flow rate of 4,970 bopd and 7.0 mmscf/d of gas at a 1,101 psi flowing wellhead pressure with initial results indicating a 39 degree API fluid.
Shaikan-5 Appraisal Well
The Shaikan-5 appraisal well, 6 km to the north-east of the Shaikan-2 appraisal well, is currently drilling at a measured depth of 1,571 metres in the lower Cretaceous to the estimated total depth ("TD") of 3,500 metres subject to technical conditions.
