<p>An apparatus and method for nondestructively measuring a sample of material to determine changes in dynamic Young's Modulus, density, static viscosity, compressive strength and expansion or contraction of a material over a period of time and at substantially constant temperature and pressure. Samples of particular interest are cements and completions gels whose characteristic dynamic Young's Modulus, density, viscosity, compressive strength and expansion or contraction at down-hole conditions are particularly important to the petroleum industry.</p> |
