A method has been developed for interpretation of Pressure-Temperature-Spinner (PTS) surveys. Drift-flux and homogenous flow models are evaluated for application in two-phase flow in geothermal wells. It was found high fluid velocity makes possible simple assumptions regarding holdup and friction losses. The analysis method provides sufficient resolution to determine mass contribution and enthalpy of individual feed zones in geothermal wells. Technique is described and a field example provided.
