Abstract: It is considered improper that breakthrough pressure is used to evaluate caprock quality. Therefore, true displacement pressure of caprock is obtained with correction of breakthrough pressure with respect to tim and temperatere. Finally, a method of estimating displacement pressure of caprock is presented.

Key words: Caprock, Breakthrough pressure, Displacement pressure, Correction
