Vapor Mass Ratio Measurements in Geothermal Production Wells

Abstract

Measurements in geothermal wellbores are very difficult because of the high fluid pressures, high borehole temperatures, and limited data transmission links. Here the extraneous effects on transducers and associated signal conditioning are very difficult to eliminate an dif no carefully controlled may be the only variables measured. All the effects of these sever environments are not found in text books but come primarily through experience. Calibration of all transducers and instruments under simulated environmental conditions is absolutely essential. All materials and equipment use in the instrumentation systems must be carefully chosen, well understood and properly used. The time and effort spent in good planning and preparation will greatly increase the probability of meaningful data processing and prove to be much more efficient.
