ABSTRACT:
A pressure measurement system particularly suited to use in boreholes uses a pressure source at the surface to supply a test fluid through a small tube to a large downhole chamber having a fluid port on its bottom side. The test fluid displaces borehole fluid from the chamber after which the pressure of the test fluid is measured at the surface, thereby indicating the pressure of the borehole fluid.
