Abstract
A method for measuring the deformation of elastomeric materials using acoustic signals involves obtaining a sample, positioning the sample in a sealable chamber, sealing the chamber, and setting a temperature and pressure inside the chamber. A test fluid may be introduced to the chamber. An acoustic signal is used to measure a characteristic of the sample, such as a dimension or a modulus. Repeated measurements may be made overtime to monitor changes in the sample in response to temperature and pressure. The acoustic signal may be generated by an acoustic transducer including a backing component including a fluorine-containing polymer in which metal particles are incorporated. The sample may be a non-metallic material. Conditions inside the chamber may be set to simulate a wellbore environment.
