Abstract
A gauge system and method for monitoring well pressure at temperatures in excess of 300° C. used in permanent monitoring of oil and gas wellbores. The gauge system includes an analog output transducer and a long cable which is an extruded mineral insulated multi-core cable with a seam welded corrosion resistant metal outer sheath. The transducer is enclosed in a pressure tight corrosion resistant housing and the housing is pressure sealed to the metal outer sheath. The method includes applying signal conditioning and processing to the measurements to compensate for characteristics of the transducer, the cable and the environment and thereby provide continuous monitoring of the wellbore.
