7- 1 chapter 7: CAPILLARY PRESSURE Objective To measure CAPILLARY PRESSURE of unconsolidated sand packs. introduction CAPILLARY PRESSURE is important in reservoir engineering because it is a major factor controlling the fluid distributions in a reservoir rock. CAPILLARY PRESSURE is only observable in the presence of two immiscible fluids in contact with each other in CAPILLARY -like tubes. The small pores in a reservoir rock are similar to CAPILLARY tubes and they usually containing two immiscible fluid phases in contact with each other. Thus CAPILLARY PRESSURE becomes an important factor to be considered when dealing with reservoir rocks. When two immiscible fluids are in contact with each other in a CAPILLARY tube, a clear interface exists between them.
