| Summary: | Geothermal reservoir is a prime part of geothermal system which it's energy directly exploited. This part's included hydrologic system, geologic's structure, heat source, and involve mass and energy transport. It is necessary to have geothermal reservoir model in order to predict reservoir performances during the time. A proper reservoir model will be resulted by appropriate modelling which approximation delineates the nature. Several studies of two phase geothermal reservoir modelling have been conducted by scientists and engineers and some of them resulting reservoir simulator based on integration method. In this paper, the modelling is build based on finite difference method in order to build a simulator that's able to delineate reservoir's physics parameters such as enthalpy and pressure distribution.<p>In this modelling, geothermal reservoir is assumed to be in closed system without any mass in or out from reservoir, and the energy are received continously from reservoir's boundaries. Geothermal reservoir's fluids are considered to be twophase fluids and the initial condition of the fluids are water dominated. Therefor, liquid phase will be dominantly influences the fluids's dynamic and energy transport. Then, the mass and energy conservation formula of this modelling can be governed within semi incompressible conditions. The results will be in pressure and enthalpy distribution changes during the time, and will be compared with other researches through literature study. Closed system conditions of geothermal reservoir causes the reservoir pressure to be quasi static of time. The result indicates the increasing of vapour quality/dryness if closed hydrothermal systems supplied by constant and abundance energy. The dryness increase esspecially in response to pressure's quasi static of time and enthalpy increasing. <br />
