Paper Number: SPE-218505-MS
... experiment permeability flooding experiment surfactant flooding adsorption isotherm additive adsorption Introduction In low-permeability reservoirs, more than half of the pore channels do not participate in filtration and the oil is blocked due to the small pore size. If the reservoir is water...
