We operate a triaxial testing system from Metarock designed
as a research solution for evaluating mechanical rock properties.
The system consists of a single innovative 200k lbs load frame utilizing twin
precision aligned ball screws and a high pressure (20,000 psi) and temperature
(160degC) triaxial testing vessel. In addition, ultrasonic acoustic
measurements and dual pore pressure loops inside of the vessel further enhance
the testing and monitoring capabilities. Specifically designed software aids in
running fully automated and highly precise test sequences and load cycles with
this equipment. Hence, rock specimens up to 1.5" in diameter and 3"
in length can be subjected to realistic in situ stress, temperature, and pore
pressure conditions down to several km depth. With this, their mechanical
behavior during loading and unloading can be monitored and analyzed providing
important understanding of rock deformation and quantifying their specific
parameters that are critical for describing and forecasting mechanical rock
behavior in the reservoir during drilling, production, and injection.
