AAPG Memoir 67: Seals, Traps, and the Petroleum System. Chapter 1: Comparison of Seal Capacity Determinations: Conventional Cores vs. Cuttings

Comparison of hydrocarbon column heights (HCHs) calculated from seals recovered in conventional cores with HCHs calculated by using cuttings from the same interval indicates that mercury/air capillary pressure measurements of cuttings can be extremely useful to estimate seal capacity. An empirical adjustment factor (EAF), expressed in psi, needs to be added to the capillary pressure value determined on cuttings to approximate that measured with mercury/air capillary pressure of conventional cores.
