Oymantepe (East Sadak)

About 60 percent of the world's oil reserves and 41 percent of the world's gas reserves belong to the Middle East countries. Many of these are in the Middle East Cretaceous oil trend. Over 70% of the Middle East oil was generated from Jurassic-Cretaceous sediments. Some of these source rocks include the Jurassic-Lower Cretaceous organic rich shale dominated carbonates and age equivalent limy-shale formations in Iraq, SW Iran, Saudi Arabia, and SE Türkiye. Limestone and dolomite reservoirs of the Middle East have fairly good porosity and permeability. Primary porosity has been well preserved in the cretaceous carbonates (pack stones and grain stones) widely spread in the Middle East. The main targets in this part of Southeastern Türkiye are all Cretaceous in age, although in Siirt to Şırnak area the Triassic is also hydrocarbon bearing, and in other parts the Jurassic may be prospective. What started in 2014 with the East Sadak-1 well discovering oil in an upper Cretaceous carbonate sequence continues across the Middle East oil trend.

East Sadak (Oymantepe) Lease ‘ARİ/AME-SNR/K/M48-a3-1’ is covering an area of 7.652 hectares, in the city of Siirt on the southeastern part of Türkiye and neighboring productive oil fields in Raman and Garzan. East Sadak (Oymantepe) oil field was discovered with a 43 API gravity oil from Cretaceous reservoir levels in 2014 by AME.
