ShaMaran Petroleum has announced the results of the Atrush-4 appraisal/development well (“AT-4”) drilled in the Kurdistan Region of Iraq.
The AT-4 well was spudded on October 20, 2013 using the DQE31 drilling rig and reached Total Depth of 2916m MD on January 23, 2014. The well was deviated well from the AT-1 well pad with the bottomhole location approximately 2.2 km SE of the surface location.
Three separate cased hole drill stem tests were conducted in the Jurassic reservoir with maximum rates totalling 9059 bopd of 27-28 API from two of the tests. None of the tests produced formation water. Downhole samples for PVT analysis and surface samples for oil assay studies were taken.
Well testing operations were completed on April 7, 2014. AT-4 has been suspended as a Phase 1 producer. The drilling rig is now moving to drill the Chiya Khere-5 development well (“CK-5”; 2014 revised well nomenclature) which is expected to spud in May 2014.
