Hannon<ref name=ch09r24 />) calculated only [[length::100 ft]] [[depth::(30 m]]) of [[seal capacity]] for this field. His calculations assumed a breakthrough pressure of 10-15 psi (69-103 kPa), based on “a multitude of capillary pressure curves” that he did not document. Yet we can estimate several reasonable breakthrough pressures from any given capillary pressure curve, depending on the assumed nonwetting phase saturation.
