Laboratory Measurement of Capillary Pressure: Dynamic Capillary Pressure Method

Figure 2‑60 shows schematically the apparatus used in this method. This involves injecting the two fluids into a rock core simultaneously, and producing one behind a semi-permeable membrane. Simultaneous steady state flow of two fluids is established in the core. By the use of special wetted disks (semi-permeable membrane), the pressure of the two fluids in the core is measured and the difference is capillary pressure. The saturation is varied by changing the rate of one fluid.
