Field history
Discovery April 13th 2011[2]

Atrush Field is an oilfield near Dohuk, Iraqi Kurdistan. It was discovered by the Consortium of General Exploration Partners. As of March 12, 2013 the Kurdistan Regional Government (KRG) has exercised its option to acquire a 25% Government Interest of the Atrush Field according to the PSC contract.[3]

Atrush Field Naming Conventions

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:[4]

Wells

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.[5][6]

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,[7] 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.[8]

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,[9] estimated to have been the highest flow ever in Iraqi Kurdistan.[10] 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.[11]

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.[4]

AT-4 Well Summary

Chiya Khere-8 (CK-8) Well

Chiya Khere-8 (CK-8) well[4]

Chiya Khere-6 (CK-6) Well

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.[12]

Well Testing

DST #1[12]
  • Formation: Alan[12]
  • Perforated interval: 12 metres[12]
  • Using an Electric Submersible Pump (ESP) and nitrogen lift the heavy oil was produced at a low rate.[12]
  • The test interval was the deepest from which oil has been recovered. At -460 m below sea level, the CK-6 oil was found to be almost 200 m deeper than the oil recovered from the equivalent reservoir in well AT-2.[12]
  • The viscosity of the recovered oil was lower than the oil from AT-2.[12]

Future wells

Two additional wells are planned to be drilled in 2013.[13] Technical discussions on the final location of the Atrush-4 and Atrush-5 wells are underway.[14]
