Evaluation of Oil Fields in and Around Diyarbakır (SE Anatolia of Turkey) in Terms of Production

Abstract

This study aims to give information about the oil production of 42 Oil Fields and the wells of each field in Diyarbakır and the surrounding area where is geologically located at the boundary of Anatolian plate and Middle Eastern oil region in the Southeastern Anatolia of Turkey. The structure of oil reservoirs at this region, the interaction of oil and water at the reservoir, capping mechanism of reservoir oil and water are the given topics about the reservoir. Average drilling depth of oil wells at the surrounding area, chemical structure and physical properties of production formations, calculation of production rate, pump types and selecting the suitable type of pump for several production rates, advantages and disadvantages of the pump types are also the other given information about the region. Moreover, regional evaluation of the oil and water ratios, API gravity of produced oil, salinity and pH values of produced water are mentioned by using the analysis of samples taken from the wells in different regions of Diyarbakır province. The other purpose of the study is to inform about stocking of produced oil and water by using surface systems, seperation systems of oil from the water, injecting of seperated water to water injection wells, analysing the downhole and surface equipment failures for production wells and enviromental effects of oil production. Giving information about the economical aspect of the oil production for Turkey and Diyarbakır region is also one of the other goal. Solutions are offered for the encountered problems during the production, separation, transportation, and the refinery processes of the reserves in Diyarbakır city of Turkey, that imports most of its petroleum and natural gas use despite being very close to relatively large reserves.
