This command is similar to the Capillary Pressure Curve command, but especially designed to simulate mercury invading a structure within a vacuum. This method is often called Mercury Porosimetry and is used to derive pore size from measured pressure values.

In GeoDict you can simulate Mercury Intrusion Capillary Pressure (MICP), where mercury is invading the structure, and (optional) Mercury Extrusion Capillary Pressure (MECP), where mercury leaves the structure. In the both cases the Pore Morphology Method and the Young-Laplace equation are used.

The MICP simulation results provide information about the pore throats sizes, while the MECP measures the size of the pore bodies. Additionally, the residual mercury remaining in the pore space is determined. For mercury intrusion it is possible to apply the Thomeer model to predict the non-resolved porosity.
