In this work we present results from nuclear magnetic resonance (NMR) spectroscopy characterization applied to both dilatant and compactive failures generated by triaxial geomechanical testing on outcrop chalk saturated with two distinct brines: CaCl2 based and CaCO3 equilibrated water. We identified open fractures, pore collapse and micro-fractures from the NMR results.
Plugs saturated with CaCl2 brine behaved more ductile than the CaCO3 saturated ones. NMR allowed a better insight on the degree of plastic deformation in triaxial tests than interpretation of stress/strain curves.
