The restoration of core natural wettability (artificial aging) is used for extracted rock samples intended for filtration and other special studies. For this, core samples are saturated with reservoir water (or its model), which is then displaced to residual values by reservoir oil. In this “initial” saturation state the samples are aged under reservoir RT conditions for the required time (up to several weeks) with periodic filtration of “fresh” oil through them. Achieving natural wettability is determined by stabilizing of electrical resistance values and oil permeability.
The “PIK-VS” installation consists of two independent thermostatically controlled channels, including 8 core holders, own automatic maintenance systems of crimp pressure, pore pressure, back pressure, as well as thermal stabilization system.
