Paper Number: URTEC-2902828-MS
... Modulus and Poisson's Ratio) have long been used as key parameters to design stimulation treatments in unconventional reservoir systems. However, conventional plug or full diameter rock mechanics measurements are commonly widely spaced. In contrast, Leeb Hardness measurements made on core slabs are fast...

Paper Number: URTEC-2460490-MS
.... Additionally, Leeb hardness tests were conducted to better understand the rock strength. Previous geomechanical studies on Eagle Ford Shale and Niobrara Formation have suggested a good correlation between rock hardness and unconfined compressive strength. In contrast to the traditional triaxial and acoustic...

... ball indenter is launched by spring against the sample; the ratio of the rebound velocity to impact velocity determines the Leeb hardness value. The Equotip was originally designed for testing metals, although recent studies have employed this tool to improve geomechanical characterization of core...
