In order to evaluate the change in flow characteristics of a geothermal production well with increasing the drilling depth, two-phase flow analysis in a wellbore was carried out assuming the well inlet condition. Pressure at the well inlet was given by the vertical pressure profiles of saturated water whose water level was located at 0m and -100 m, and inlet steam quality of x1= 0 was used. The steam and water flow rates of a 3000 m deep well at a constant well head pressure (P2 = 10 ata) are estimated 194 t/h and 183 t/h respectively.
