Methods and systems are provided for evaluating rock specimens subjected to high pressures and temperatures by ultrasonic evaluation utilizing various transducer enhancements. Certain embodiments contemplate configuring ultrasonic evaluation systems to provide more accurate measurements, enhanced protection of transducer elements, fewer metal interfaces between transducer elements and test specimens, and easier access to transducer elements for maintenance and replacement. Additionally, certain embodiments allow for sequential or simultaneous p-wave and s-wave measurements of a test specimen. These enhancements translate into a more accurate and efficient ultrasonic evaluation system offering higher resolution measurements.

Ultrasonic transducer system and evaluation methods

Apparatus and methods for estimating a physical property of a specimen, particularly the specimen strength, are provided. More specifically, a roller indenter comprising an indenting wheel and a force indicator is used to create an elongated trough in a specimen. The width of the trough is measured as a plurality of locations and correlated with a known standard to provide an estimate of the strength of the sample.
