Capillary Pressure and Resistivity System

Manufacturer: Vinci Technologies
Model Number: CAPRI-700

The CAPRI 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. The instrument consists of a core holder furnished with hydrophobic and hydrophilic ceramics and electrodes pattern for resistivity measurement, an automated pumping system for fluid control and a resistivity cell for brine resistivity measurement. The whole is housed in a temperature controlled air bath.
