Gulf Keystone (GKP) today provided 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
Gulf Keystone has completed drilling of the Shaikan-4 appraisal well, 6 km to the west of the Shaikan-1 discovery well, to a total depth (TD) of 3,387 metres in the middle Triassic with 2,375 metres of total gross pay interval. The well has been drilled through the Jurassic (Sargelu, Alan, Mus and Butmah formations) and the upper and middle Triassic (Baluti, Kurre Chine A and Kurre Chine B formations) with an indication of potential new Jurassic reservoirs in Sargelu sands and Barsarin carbonates.
The Company is now embarking on a well testing programme for Shaikan-4 which will target several formations in the Jurassic and Triassic, including the Chia Gara/Barsarin, Sargelu, Butmah, Kurre Chine-A, Kurre-Chine-B and Kurre Chine-C formations.
Preliminary results from Shaikan-4 formed part of the new data used by Dynamic Global Advisors (DGA), independent Houston-based exploration consultants, to calculate the most recent significant upgrade of the gross oil-in-place volumes for the Shaikan discovery announced in November 2011.
Shaikan-5 Appraisal Well
The Shaikan-5 appraisal well, 6 km to the north-east of the Shaikan-2 appraisal well, has drilled to a measured depth of 856 metres and 20" casing is currently being set. The well will then continue drilling to the estimated TD of 3,500 metres subject to technical conditions.
