Often, pressure-gauge systems for surface read-out (SRO) wireline work or for permanent installations do not perform according to their specifications; i.e., the pressure resolution obtained is lower than the gauge-design values. This seems natural because the borehole environment is nastier than the quiescence of laboratory calibration set up. Nevertheless, it is difficult to attribute the loss of resolution to a single problem. This paper introduces the functional components of the pressure-gauge system where loss of resolution may occur. Specifically, it addresses cable-related problems, crossover, signal transmission, signal processing, time stamping, and temperature compensation. We show determination of pressure resolution from a processed signal by means of example calculations. The role of transducer specifications on overall data quality is addressed; i.e., what causes a 0.01-psi-rated transducer to yield a signal of only 0.75 psi quality? Field data from Tahoe and Bullwinkle prospects are used to illustrate some of the gauge-related problems and the solutions being proposed by the industry to overcome some of them.
