Paper presented at the 55th U.S. Rock Mechanics/Geomechanics Symposium, June 18–25, 2021
Paper Number: ARMA-2021-2121
... ABSTRACT: Injection of fluids in the subsurface can induce seismicity and possibly lead to rock failure. Earthquake nucleation could be triggered by pore fluid diffusion or changes in pore fluid composition. Thus, microcracking processes before the formation of macrofracture in fluid-saturated...

... in contact with injected CO 2 . Through diffusion, and concentration gradient, the injected CO 2 mixes with the caprock pore fluid, modifying its pH from basic to acid. Different experiments are performed to demonstrate the effect of CO 2 on mechanical properties of the North Sea Draupne shale caprock...

.... In the end, the authors gave the trend of deviator stress-angle effected by water-oil content, then the relative analysis were given from the facts of capillary pressure, hydration reaction and pore pressure. Some conclusions were reached: (1) Due to the pore fluids, the maximum and minimum slip angle...
