<p>A pressure data validation method which measures differential pressure along with measuring the absolute pressure while testing a well. The method uses a differential pressure gauge having a known distance between the two differential pressure measuring gauges, wherein the pressure differential indicates fluid density. During the test, as each absolute pressure reading is taken, a differential pressure reading is also taken and this reading is used to determine the density of the fluid surrounding the gauge at the time of the measurement. Each measurement is compared to previous measurements, and a change in fluid density, and thus a change in the type of fluid, is displayed to indicate that any discontinuity in the pressure display is due to a fluid boundary.</p> |
