The CRI-PR01 system is dedicated to the determination of the capillary pressure curves (positive and negative) and the electrical resistivity index as a function of core sample saturation at reservoir conditions. Saturation exponent “n”, formation factor and cementation exponent “m” are also calculated. Knowledge of the water-oil capillary pressure and resistivity index vs. saturation relationship is necessary for many reservoir- engineering tasks:
Assess connate water saturation to calculate oil in place;
Calibrate resistivity logs;
Determine the height of the transition zone;
Model oil displacement either by free water imbibition and/or water injection
