An apparatus for measuring volumetric changes in cement as the cement is exposed
to pressures and temperatures to simulate down-hole conditions, in a high-pressure
high-temperature chamber is described. The apparatus is described a mold having
a first section adjacent a base and a second section movably attached to the first
section and adjacent the base in which cement may be placed. The apparatus includes
a sensor to measure the movement of the first and second sections relative to one
another in response to volumetric changes in the cement. Also described is a method
of measuring the volumetric changes in cement as the cement is exposed to simulated
down-hole pressures and temperatures in a high-pressure, high-temperature chamber.
