Reservoir access is key to exploitation of unconventional gas reservoirs. CBM Solutions' geomechanical stratigraphy program is specifically designed to provide our clients with the necessary rock mechanical properties that are critical for borehole stability and frac design. When our geomechanical stratigraphy is linked with our stress sensitivity permeability analyses, our clients are armed with the key tools for screening gas shales and coal seams for exploration and exploitation through optimization of drilling and completions.
All mechanical tests are carried out using a servo controlled triaxial apparatus under prescribed stress states and pore pressures. We can deform whole core samples ranging from 1 inch to 4 inches in diameter, alleviating the necessity of recoring existing core. In addition, we measure ultrasonic compressional and shear-wave velocities to collect dynamic elastic moduli that can be used for calibration of sonic logs.
Our goal is to provide our clients key rock mechanical data and relevant interpretative support in a timely manner so that the completion design can be used on the same well from which the analyzed cores are collected.
