Rock mechanics essentially affects every aspect of reservoir development including well placement, drill bit selection, drilling, stimulation & completion, and production. The vast majority of wells drilled in tight gas sand and gas shale have been hydraulically fracture stimulated. While pumping rate and fluid properties can be changed, rock properties remain constant and uncontrollable. Understanding geomechanical properties of reservoir is the key component in reducing the uncertainties and maximizing frac design optimization.
Equally important in the poorly consolidated reservoirs are sand control and wellbore instability issues. Accurate failure criteria of reservoir rocks based on triaxial compressive tests and Mohr-Coulomb failure analysis are critical to proper implementation during drilling and production.
