Abstract
A method was developed for measurement of downhole enthalpy of two-phase geothermal wells. It is proposed that change of chloride concentration along the wellbore can be utilized to calculate downhole enthalpy, which is inspired by an equipment that enables relatively accurate measurement of chloride concentration in the geothermal fluid. A model that relates chloride concentration with enthalpy was built up. Experiment verification of the method was also provided.
