In 2014 after a meeting of the Atrush Management Committee and the KRG Ministry of Natural Resources changes in terminology used with respect to activity in the Atrush Field were made:

Atrush Field Overview TAQA

  • “Atrush Block”, “Atrush PSC” & “Atrush Field” were unchanged.
  • The structure (previously referred to as the “Atrush structure”) is renamed after the Chiya Khere mountain, i.e. the Chiya Khere structure.
  • All production facilities will be known as the Chiya Khere facilities.
  • Future wells will remain sequential but will be referred to as “Chiya Khere”, short-form “CK”, commencing with well #5.
  • Well pads will be known as Chamanke-A, -B, etc.
  • Historic wells, AT-1 through AT-4, will retain their original nomenclature.

    • Atrush-1 (AT-1) Well

    Atrush-1 (AT-1) well was successfully spudded on October 5, 2010. The well had a natural flow of 6,393 barrels of oil per day. General Exploration Partners discovered 726 meters of oil column and 120 meter netpay.

    General Exploration Partners (GEP) held 80% of Atrush-1 and was in cooperation with Aspect Energy International, whom owned 2/3 of GEP, thus Aspect Energy International had a share of 53,2%. Aspect Energy International sold its interest in GEP to TAQA for $600 mln, which basically transferred Aspect's interest in GEP to TAQA. Shamaran's interest remains at 26,8% of Atrush-1, and the remaining 20% is held by Marathon Oil.

    Atrush-2 (AT-2) Well

    Atrush-2 (AT-2) well was successfully spudded on May 23, 2012. The well had a flow of 42212 barrels of oil per day using a Submersible pump, estimated to have been the highest flow ever in Iraqi Kurdistan. The design of the DST Program as well as the permanent completion was managed by Richard Sharpe, Damon Yarshenko, and Wes Whitman with key execution support provided by core contractors.

    Atrush-3 (AT-3) Well

    Atrush-3 (AT-3) well is planned to spud during the month of March 2013, it is believed the well spudded on the 26th of March but there is no information confirming this for now.

    Atrush-4 (AT-4) Well

    Drilled in 2014, Atrush-4 (AT-4) well is the second well to be drilled in support of the Phase One Facility.

    AT-4 Well Summary

  • High-angle deviated well. 82° was the maximum hole angle. This demonstrated that the field could be developed, using directional wells in the face of extremely rugged terrain.
  • The well was drilled from the AT-1 pad, which is correctly known as Chamanke-A.
  • The Jurassic reservoir is approximately 72m higher than when it was encountered in AT-1.
  • Two limited well tests were performed for fluid samples.
  • The combined rate of fluid production was over 9,000 bopd of 26°API oil.
  • There wasn't an indication of a gas cap.
  • An interfence test was also conducted. The test demonstrated instantaneous pressure communication with AT-2.
  • AT-4 was suspended as Phase One Facility producer.

    Chiya Khere-6 (CK-6) Phase 2 appraisal well has a total depth of 2,105 metres. The TAQA-operated well reached TD on November 5, 2014, after 36 operational days. Part of the eastern part of the Atrush block the well is located on the Chamanke C pad. This pad is also the location of AT-3. CK-6 is a directional well, drilled in SSE direction from surface. CK-6 encountered the Jurassic age reservoir at a higher elevation (~139 metres) than the nearby AT-3 well.

    Future wells

    Two additional wells are planned to be drilled in 2013. Technical discussions on the final location of the Atrush-4 and Atrush-5 wells are underway.
