Experimental study on residue oil distribution after the supercritical CO2 huff-n-puff process in low permeability cores with Nuclear Magnetic Resonance (NMR)
In this paper, two sandstone cores with permeabilities of 1.7mD and 2.6mD were employed and the ScCO2 huff-n-puff processes were carried out to check the oil recovery efficiency as well as the oil mobilization laws under the conditions of 50 °C and 25 MPa. Both cores were cut half after the completi...
