Capillary forces together with the gravitational forces control the initial distribution of fluids in the reservoir-the reservoir vertically so the data on capillary pressure curves can be used to forecast the fixed and movable water in the hydrophobic system vertically. Capillary pressure curves are needed to describe the process of waterflooding in complex, heterogeneous formations, are used as well to determine the residual water saturation and the distribution of pore size. It should be noted that capillary forces affect the promotion of the front of the institution and consequently on the ultimate oil recovery.

Curves of capillary pressure, surface tension, radius of the pore, relative permeability
