Taqa flows oil at CK-6 well in Kurdistan

20th January 2015

The Taqa-operated Chiya Khere-6 (CK-6) Phase 2 appraisal well in Kurdistan (part of the Atrush Phase 2 area appraisal) was drilled to a total depth of 2,105 metres which was reached on November 5, 2014, after 36 operational days, ahead of plan and budget

The drilling rig has moved to the adjacent AT-3 well to conclude testing operations suspended in 2013

The CK-6 well is located in the eastern part of the structure and was drilled from the same well pad as the Atrush-3 appraisal well (AT-3), the Chamanke-C pad. The well reached the Jurassic reservoir approximately 139 metres structurally higher than the nearby AT-3 well, approximately 600 metres south-south-east of the surface location.

Logs indicated that the matrix reservoir quality and degree of fracturing across the main reservoir zone were the best in any well drilled to date in Atrush. Three well tests were conducted with results as follows:

DST#3 was conducted over a perforated 24-metre interval in the Naokelekan formation. The zone was flowed using ESP at rates up to 6,787 bopd (constrained by surface testing facilities) of 26.6° API oil.

DST#2 was conducted over a 48-metre interval in the Lower Sargelu formation. During the main flow period the zone was flowed using ESP at rates up to 3,792 bfpd of emulsion. Bottom hole samples are pending laboratory analysis to provide the gravity of the oil at reservoir conditions.

DST#1 was conducted over a perforated 12-metre interval within the Alan formation. The zone flowed heavy oil post-acid with ESP and nitrogen lift at a low rate. The tested interval represents the deepest recovered oil in the field to date (-460m), nearly 200m deeper than the equivalent interval that successfully tested the higher viscosity oil in the Atrush 2 well.

Full analysis of CK-6 well testing results is subject to ongoing data evaluation and laboratory tests.

The drilling rig has moved to the adjacent AT-3 well to conclude testing operations suspended in 2013.

The Atrush Block is operated by TAQA Atrush BV (TAQA) and is held 39.9 per cent by TAQA, 20.1 per cent by ShaMaran Petroleum Corp through its wholly owned subsidiary General Exploration Partners, Inc., 15 per cent by Marathon Oil KDV B.V., (a wholly owned subsidiary of Marathon Oil Corporation), and 25 per cent by the Kurdistan Regional Government of Iraq.
