High pressure mercury injection
WebIn these Mercury Injection Methods, high pressure mercury was injected into the core sample and the volume of mercury entering the core was measured. These methods had several drawbacks, including the destructive nature of the test and the compression of any gases in the core sample retaining a residual volume, resulting in measurement ... WebThe high-pressure mercury injection capillary pressure (MICP) analysis was carried out using a Mi-cromeritics 9420 mercury porosimeter. Penetrometers with 15 cc sample chambers were used for all analyses. Each test utilized a pressure table containing 118 sepa-volume of mercury injected was measured at each point.
