Abstract
Abstract In this research project, functionality, and repeatability of a low-cost custom geomechanical properties testing system that had been built for studying the mechanical behaviors of hydrocarbon bearing reservoir rocks and overlying seals, was tested and calibrated. For this, unconfined uniaxial compression tests were performed for generating transvers microstrain and axial microstrain curves for two standard metals namely aluminum and copper. The experimentally measured Poisson's ratio values were compared with the published values. The results were found comparable. The experimental work conducted in this project has provided an opportunity to fine tune the experimental procedures needed for performing uniaxial and reservoir condition triaxial testings of the representative samples of reservoir and overlying cap rocks of potential geologic CO2 storage sites. Such expermients will greatly assist in determining the ability of potential geologic CO2 storage sites in California in storing injected CO2 in safe and effective manner.
