Results of Laboratory Scale Fracture Tests on Rock/Cement Interfaces

[摘要] A number of pure cement and cement-basalt interface samples were subjected to a range of compressive loads to form internal fractures. X-ray microtomography was used to visualize the formation and growth of internal fractures in three dimensions as a function of compressive loads. This laboratory data will be incorporated into a geomechanics model to predict the risk of CO2 leakage through wellbores during geologic carbon storage.
