Mercury Capillary Pressure System

Mercury Capillary Pressure System

Manufacturer: Vinci Technologies
Model Number: CPM-140

Manually operated system that determines capillary pressure and pore volume by virtue of Purcell’s method. A dry core sample is placed in a core holder whose configuration allows easy sample loading/unloading and bulk volume measurement by means of mercury level visualization via a see through window located near the inlet. The core holder is then evacuated and a subsequent mercury injection up to 2,000 psi (140 bar) is performed by means of a nitrogen gas supply. At each pressure increment, the volume of mercury in the core holder is measured with the manual rotary crank pump. The correlations developed by Purcell can then be used to convert mercury capillary pressure to air/water capillary pressure and also get estimates of permeability
