level is defined as the elevation where the capillary pressure is zero. The above equation gives the mapping between the elevation and the capillary pressure. The capillary pressure is proportional to the elevation above the free water level and the constant of proportionality is the product of the density difference and the acceleration due to gravity.

In reality, capillary pressure and relative permeability effects are often coupled in a single flow experiment, and their separation requires the use of a numerical simulator (Archer and Wong, 1973; Sigmund and McCaffery, 1979 and Tao and Watson, 1984). To solve for capillary pressure and relative permeability numerically from two-phase flow Thomeer (1960) observed that the capillary pressure data from MICP experiments can be fitted with a hyperbola by using three fitting parameters like G, Pd, and \left ({V_ {\text {b}} } \right)_ { {P_ {\infty } }} as shown in Eq.

He approximated capillary pressure profiles from experimental data in a log-log plot to a hyperbolic function (Equation 2.13). /log ( ) The Thomeer hyperbolas so determined are converted to capillary pressure curves. Continuous capillary pressure (P c ) curves of subsurface rock formations adjacent wells are determined based on translation relaxation time (T 2 ) data from nuclear magnetic resonance (NMR) and from wireline well logs, such as resistivity logs, to obtain water saturation (S w ) of the rock in the formations.

Abstract. A method is presented that provides a mathematical description of capillary pressure curves and, probably, of differences in pore geometry of samples. The technique is based on the observation that the location and shape of a capillary pressure curve reflect characteristics of the pore structure of the sample.
