Below [[depth::9000 ft]], the seal capacity is greater for gas than it is for any of the oil compositions. Even above [[depth::9000 ft]], the seal capacity for gas is greater for some oil compositions. The seal capacity for gas is greatest at a normal pressure gradient and less for an overpressured gradient. | Below [[depth::9000 ft]], the seal capacity is greater for gas than it is for any of the oil compositions.
