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.
