Practical Experiences About Reservoir Monitoring in Alasehir Geothermal Field

Abstract

Alaşehir geothermal area that is located in southern part of the Alaşehir Graben is one the important geothermal areas in Turkey. Currently, more than 6 operators are exploiting this field on a strictly competitive, and largely confidential, basis without significant exchange of resource information among them. This paper discusses monitoring of the response of part of Alaşehir geothermal system to large scale exploitation. In this regard, temperature and pressure of the reservoir, steam flowrate, brine flowrate, inflow performance relation curve of production wells, non-condensable gas content, chloride and silica content of produced fluid will be reported. Significant decrease of non-condensable gas will be discussed. Some practical experiences about reservoir monitoring will be shared. Finally, evaluation of the aforementioned parameters will be discussed.
