Permanent CO₂ sequestration relies on avoiding leakage from the reservoir through the caprock. The highest leakage risk resides at the wells penetrating the reservoir, in particular at the boundary between cement sheath and formation. Models quantifying the risk of cement debonding require the...

Laboratory tests were conducted in a triaxial load frame with acoustic emission and transmission capability to investigate mechanisms that might be initiating the microseismicity experienced in CO 2 injection operations. Although often...
