Summary of 2014 & 2015 Years Exploration Activities
In 2014, GYP and its partners has worked drilling activities in 6 exploration licenses, after the discovery of Petek-1, Basaklı-1 and Incebag-1 wells, 3 exploration licenses were converted to production licenses. In July 2015, with new exploration license, GYP and its partners continue exploration activities in total 1,193 km² surface area by 4 exploration licenses.
All these projects are carried out through initial compilation of all available geological & geophysical data and later interpretation & evaluation studies in regional and prospect scale which lead to a final assessment of the hydrocarbon potential of the license area. For this purpose, data are digitized by LYNX LEASSV & LEASMAP softwares, and SMT Kingdom Suite 8.2 version is used for 2D, 3D seismic evaluation, well correlation and well log interpretation..
During the year 2014, six (6) exploration wells’ drilling was completed. As a result of exploration activities, 5 new fields Petek, Incebag, Basaklı, Dirsekli and Caybasi were discovered and wells were put on production.
GYP also drilled eight (8) production wells (Bulgurdag-19, 20, 21, 22, 23, 24, Bati Kahta-5, Arpatepe-8) in year 2014. Bulgurdag-22 well was abandoned due to high water cut, unlikely other 7 wells were put on production.
Since July 2015, AR/GYP/K/N43-d2 exploration license in Adana Region is authorized to GYP.
In 2014, total drilling depth of 14 exploration and production wells were 20,694 m. 8,422 m. were belonged to exploration and 12,272 m. were belong to production well.
AR/GYP/4919 Exploration License
In AR/GYP/4919 exploration license in Silopi, Sirnak Region, Ovakoy-1 well was abandoned at 9,000 ft (2,743 m.) depth due to drilling difficulties on April 11, 2013. Then, Ovakoy-2 well was spudded at 20 m. south of Ovakoy-1 well on September 1, 2013.
Drilling problems at Ovakoy-1 were presumed by the over pressure due to nearby thrust fault on the west and Ovakoy-2 well was deviated towards south in order to be away from the effects of the thrust fault. However, similar problems were encountered and therefore the well had to be abandoned at the depth of 8,416 ft (2,563 m.) on February 28, 2014.
A new well is planned to be drilled soon in the same location.
AR/AME-GYP-TLN/5025 Exploration License
Ambarcık-2 exploration well was spudded on September 10, 2013 in AR/AME-GYP-TLN/5025 exploration license in Bismil, Diyarbakir region. The well is completed at the depth of 9,700 ft (2,956 m.) in Bedinan Formation on December 8, 2014.
After the interpretation of well logs, 4 different zones in Bedinan and 2 different zones in Hazro and Uludere Formations were tested by perforation and swab operations on January 2014. Although, oil samples were countered at the depth of 92 ft (28 m.) higher than Ambarcık-1 well, tests conducted in Bedinan Formation resulted as dry and freshwater flow was observed in Hazro and Uludere Formations.
In other respects, in the west part of AR/AME-GYP-TLN/5025 exploration license and south of Goksu-1 well, 3d seismic surveys were conducted in 173 km2 on between the dates of November 21, 2013 and April 8, 2014. After processing and interpretation of data, Guney Gokse-1 well was located and drilling of the well was stopped temporarily at the depth of 5,585 ft (1,702 m.) in Sayindere Formation. After workover rig arriving in the location, the well was tested by penetration of Mardin Group.
AR/GYP/4968 Exploration License
In AR/GYP/4968 exploration license, Dirsekli-1 well was located on the 1km away from southwest of KD Ogunduk-1 well. Drilling of the well was started on October 5, 2013 but due to drilling rig change drilling was hold on. On March 26, 2014, drilling of the well was restarted and finished in Karababa Formation at the depth of 6,675 ft (2,034 m.) on July 5, 2014. After well completion and swab operations, sucker rod pump was installed the well and Dirsekli-1 well was put on production. Oil gravity of the well was calculated as 21.6 API.
While drilling of Dirsekli-1 well, oil samples were encountered in Gercüs Formation during DST. In order to test the zone, drilling of Dirsekli-2 well was started on November 20, 2014; however, due to stuck of drill string in Hoya Formation, the well was abandoned and relocated 5 m. away from south of the first location of Dirsekli-2 well. Dirsekli-2K well was started to drill on new location on December 3, 2014 and the drilling was finished at the depth of 2,835 ft (864 m.) on December 20, 2014. After 3 perforation and installing downhole pump, the well was put on production with 55 bbls/d rates without water cut on March 12, 2015.
AR/GYP/K/N34-d2 Exploration License
AR/GYP/K/N34-d2 exploration License in Karaisalı, Adana region is authorized to GYP in July, 2015. The License area surrounds Bulgurdag Production Field (İR/GYP/723-724 production license) where GYP is still operating. Prior to exploration drilling that is aiming to test Miocene aged Karaisalı reef limestones, collection and evaluation of data has been continued in the new License area.
3 exploration licenses were converted to production licenses by General Directorate of Petroleum Affairs approval.
AR/AME-GYP/2677 Exploration License: GYP applied to convert exploration license to production license for 1/25.000 scaled mad section where Petek-1 and Karakilise-1 production wells exist. Therefore, ARİ/AME-GYP/K/L44-d4-2 for Petek Field and ARI/AME-GYP/L44-d3-1 for Karakilise Field production licenses were authoritezed to GYP and AME by General Directorate of Petroleum Affairs approval on October 27, 2014.
AR/AME-GYP/2674 Exploration License: GYP applied to convert exploration license to production license for 1/25.000 scaled mad section where Altinakar-1 and Basakli-1 production wells exist. Therefore, ARI/AME-GYP/K/M44-b3-1 production license was authoritezed to GYP and AME by General Directorate of Petroleum Affairs approval on April 14, 2015.
AR/GYP/4244 Exploration License: GYP applied to convert exploration license to production license for 1/25.000 scaled mad section where Incebag-1 production well exists. Therefore, ARİ/GYP/K/M40-c2-1 production license was authoritezed to GYP by General Directorate of Petroleum Affairs approval on April 14, 2015.
