Apparatus and method for determining mechanical properties of cement for a well bore

Abstract

Apparatus for testing mechanical properties of a sample cement composition. The apparatus includes an annular test chamber and a variable stress system. The variable stress system communicates with the annular test chamber. The variable stress system is operable to control at least one of temperature or pressure applied to the sample cement composition in the annular test chamber during and after curing of the sample cement composition. One or more sensors are coupled to the annular test chamber. The sensors are operable to sense at least one of stress, strain and displacement from the sample cement composition in response to one or more changes applied to the annular test chamber by the variable stress system for determination of at least one mechanical property of the sample cement composition.
