Karakilise

Karakilise Production Lease is situated about 30 km North of Diyarbakır. Karakilise-1 exploration well was spudded in June 2003 and drilling operations were completed at a depth of 2472 m in Mardin Group carbonates (Karababa-C) as an oil producer well and put on the production in September 2003. The interpretation of seismic data shows that Karakilise structure is continued at Ordovician Bedinan sandstone levels also. The deepening of Karakilise-1R was started on September 2006 to test oil possibilities of the top of productive upper Bedinan sandstones. The well was completed as a ‘Dry well’ in Bedinan sandstones in November 2006. After the 31-degree API gravity oil was discovered in Mardin Carbonates in Karakilise-1 well, the drilling of Karakilise-2 appraisal well was started on November 2004 to test oil possibilities Upper Cretaceous carbonates. This well was completed as oil show at 2525 m in Mardin Group. Recently, Hakan Yılmaz-1 appraisal well was drilled on the production lease. This well was started on April 2008 and completed as a ‘Dry well-Oil show’ in Mardin Group at 2502 m depth in July 2008.

Despite successful production from Cretaceous reservoirs in the Southeastern Türkiye, Paleozoic hydrocarbon plays across parts of several oil fields or prospect areas remain relatively under-explored. The Paleozoic Petroleum System, for which upper Ordovician sandstone reservoirs capped by the thick shale of the Dadaş Formation of Silurian age were charged by Llandovery source rocks (lowermost of the Dadaş Formation). Paleozoic Prospects which are undrilled and have good potential, were defined with available data in concession area. This block is in the appraisal and development phase.
