Arpatepe

Until the late 2007s, the prevailing view about Ordovician Bedinan sandstone play was its limited area extends from some small oil fields along the southern foreland area. In 2008, the AME-led JV group discovered oil in the Arpatepe prospect. It is the first Paleozoic oil field in the country. Within the following years, many other operator companies actively exploring the Paleozoic plays in the area made several oil field discoveries of various sizes. The Diyarbakır Basin still bears the biggest Paleozoic HC potential in a largely unexplored area.

Arpatepe-1 tested 41 API oil in a 35 m gross reservoir interval of the Bedinan quartz-rich sandstone member (B4), and the well was put on production with 350 bopd with natural flow.

In 2009, a 252 km2 3D survey was carried out for better well placement for both the exploration and development phases. In this region, seismic quality is usually good for even identifying subtle structures at Paleozoic reservoir levels.

Within the exploration phase and period of field development afterward, seven more wells were drilled along the same Arpatepe fault closure. There is a total of four wells currently producing from the Bedinan sandstones.

North Arpatepe-1 well was spudded in June 2022 to test for any commercial oil accumulation in the Bedinan sandstones in a separate basement fault closure 2.2 km to the North of the Arpatepe oil field. The well didn’t reach its planned TD due to technical reasons and was temporarily abandoned in the Dadaş Formation.

TransAtlantic Petroleum's 50% working interest in the Arpatepe production lease has been acquired by AME and GYP. The new share structure is now AME 40% and GYP 60%. Governmental approval was granted and announced in the Official Gazette on 25 September 2023. The new lease name is listed as ARİ/AME-GYP/K/5003.

The workover operations are regularly performed in the producing wells. Arpatepe-1 and Arpatepe-6 wells were put back into production with production packers in March 2024.
