A B S T R A C T DETERMINATION OF STEAM QUALITY IN THERMAL INJECTION WELLS A method and apparatus for measuring the quality rate of the steam injected into a hydrocarbon formation in a thermal recovery process. The method measures the density and flow rate of the steam downhole using a mechanical/electrical apparatus. The quality of the steam is calculated from the measured density and flow rate. The apparatus comprises an electric motor-generator and turbine wheel combination, the no-load speed of the motor being related to velocity of the steam while the stall torque is related to density of the steam.
