  • Cement expansion/contraction test method
    Patent number: 6918292
    Abstract: 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.
    Type: Grant
