The impact of rock-brine-CO2 interactions are studied via custom SCAL experiments and/or pore-scale digital rock simulations that faithfully represent chemical and thermal processes. Wireline formation tester samples provide representative formation brine...

.... In a proof-of-concept experiment, we introduce a novel semi-analytical smeared-peak (SASP) technique that compensates for the over-regularized smearing, due to poor SNR, of T1-T2 relaxation responses of different fluids. The SASP approximation, to de-smear volumes of different fluid types, is validated...
