M9117 Capillary Pressure and Resistivity System
The Grace Instrument M9117 Capillary Pressure and Resistivity System is designed to examine capillary curves (both positive and negative) and check the electrical resistivity index as a determination of core sample saturation at reservoir conditions.

The system also includes a core holder made of hydrophobic and hydrophilic ceramics and uses electronodes patterns for resistivity measurement. An automatic pumping system measures fluid control, while a resistivity cell has been installed for resistivity measurement.

Saturation and cementation exponents ("n" and "m", respectively) as well as the formation factor can be calcuated during testing.
