The “PIK-OFP” installation for studying core phase permeability (2 phases, desktop version)

The PIK-OFP installation is designed to determine filtration, capacitive and electrical core sample properties during single and two-phase stationary and non-stationary filtration at reservoir conditions. The equipment is used to determine oil displacement coefficients by water/gas for evaluating effectiveness of increasing oil recovery physicochemical methods, determining relative phase permeabilities in “liquid-liquid” and “liquid-gas” systems.
