Abstract: A method of measuring cement volumetric changes includes loading a sample cement into a flexible container and surrounding the flexible container by a column of fluid in a chamber. The temperature of the column of fluid is adjusted to a cement setting temperature, and the sample cement is allowed to set over several hours. The pressure of the column of fluid is adjusted to a test pressure. The temperature of the column of fluid in the chamber is adjusted to induce volumetric changes in the set cement. As the volume of the set cement changes, fluid volume adjustments are applied to the column of fluid in the chamber to maintain the pressure of the column of fluid in the chamber constant at the test pressure. The volumetric changes in the set cement are determined from the fluid volume adjustments applied to the column of fluid in the chamber.
