Zeynel-Nemrut Lease



The Nemrut and Zeynel oil fields are located to the west of the SE Anatolian Basin in the Adiyaman area. Stratigraphy in this region starts with Precambrian units, though these units were not penetrated in this part of the basin. Precambrian units are overlain by Cambrian and Ordovician clastics including Sosink and Bedinan formations.


Upper Cretaceous Mardin Group carbonates are the most important reservoirs in the region. Karabogaz and Sayindere limestones are regarded as reservoir horizons if the fractures from Karababa reach upward into these formations. Underlying Turonian-Cenomanian aged Karababa and Derdere Formations are considered secondary targets. Pelagic facies of the Derdere Formation, and dark muddy carbonates of the Karabogaz Formation have good source rock quality. Their TOC ranges from 0.5% to 7.8% and the kerogen types are I and II. Germav Formation shales serve as the main seal rocks. The tight zones of the unfractured Karabogaz and Sayindere Formations act as local seals for the Mardin Group carbonates.


The Zeynel-Nemrut Oil Field was discovered in 1989 by AME. To date, 23 wells have been drilled in Zeynel Field, 4 wells in Nemrut Field and 4 wells in Hasancık Field and 2,3 million barrels of 23 API gravity oil have already been produced. The total monthly oil production of the Zeynel-Nemrut-Hasancık Fields is around 3.000 bbls/month. AME holds %25 WI in the concession.
