Nuclear magnetic resonance relaxometry techniques were used to quantify capillary trapping of CO2 and to determine the occupation of CO2 ganglia with respect to pore sizes in rocks at reservoir conditions. Furthermore, a novel combined ultrasonic and NMR measurement system for the study of rocks at high pressure and temperature was designed and constructed providing for new types of rock physics experiments. Finally, new insights on the dielectric polarisation mechanisms in partially saturated shale rocks were gained by utilising Tikhonov regularisation techniques to compute dielectric relaxation time distributions from broadband (40 Hz to 110 MHz) dielectric data.
