...; therefore, specimens with various crystal orientations are tested and evaluated. The specimens investigated in cyclic tests at 70%–80% of their unconfined compressive strength did not exhibit a significant change in their Young's modulus and damage parameters even after 30 cycles. However, the specimen...

... ABSTRACT: Unconfined compressive strength (UCS) is the simplest, least-expensive, most commonly used and understood parameter by professionals in Geomechanics. UCS results obtained from lab testing are used in various petroleum geomechanical workflows for calibrating log-based UCS estimations...

... ABSTRACT: Unconfined compressive strength (UCS) is the key parameter to; estimate the in situ stresses of the rock, alleviate drilling problems, design optimal fracture geometry and to predict optimum mud weight. Retrieving reservoir rock samples throughout the depth of the reservoir section...
