I am interested in modeling reservoir dynamics in the high-enthalpy geothermal system as a result of utilization. The main approach employs static and numerical models involving structure geology, geochemistry, and reservoir properties. The goals are to understand the geothermal system before and after utilization, to prevent over-utilization, and to suggest further well-targeting. The most important aims to maintain the long-term sustainability use in the producing high-enthalpy geothermal field
