Alternatively, some workers define P<sub>d</sub> as the pressure at the first inflection point of capillary curve.<ref name=ch10r42>Katz, A., J., Thompson, A., H., 1986, Quantitative prediction of [[permeability]] in porous rock: Physical Review Bulletin, vol. 34, p. 8179–8181., 10., 1103/PhysRevB., 34., 8179</ref> Figure 10-49 above shows the inferred P<sub>d</sub> at both 10% saturation and at the inflection point.
