A system for forming a seal between wellbore components includes an annular seal having a first leg and a second leg, the first leg positioned proximate a first wellbore component and the second leg positioned proximate a second wellbore component, wherein upon activation of the seal, the first leg engages the first wellbore component and the second leg engages the second wellbore component. The system also includes an energizing ring adapted to activate the seal, the energizing ring extending into an opening of the seal to drive the first leg and the second leg radially outward relative to an axis of the seal. The energizing ring includes bumps positioned to align with respective grooves formed on both the first leg and the second leg, upon activation of the seal, the bumps transmitting an uphole force into components having an axial component and a radial component.

A system is disclosed as including a seal for sealing an area between a hanger and a housing of a wellhead. The seal is provided with at least a notch that defines at least a movable portion such as a wing or a lip. An e-ring is provided for a first energizing of the seal. The movable portion enables pressurized fluid from beneath the seal to cause the movable portion to protrude further against a mating side in the wellhead and the hanger for a second energizing of the seal. This type of seal maintains or improves the sealing of the wellhead in high pressure applications. Methods applied to the above seal are also disclosed.
