Scope: Restoration of core sample to the initiate reservoir condition
In the most of Special Core Analysis experiments, initial wettability of the core is a vital factor of the sample. Hence, it is necessary to restore it before performing the experiments.
In this experiment, the core sample is restored to the irreducible reservoir water saturation conditions using proper reservoir crude oil. The sample remains at the reservoir pressure and temperature conditions for several weeks in order to restore the initial reservoir wettability condition.
