Abstract
A tubing or casing hanger seal assembly is disclosed including an actuation sleeve to be mounted on a tubing hanger, a shoulder member to be mounted on the tubing hanger, and a seal assembly disposed between the actuation sleeve and the shoulder member. The seal assembly includes a first set or pair of seals engaged at a tapered interface, and a second set or pair of seals engaged at a tapered interface. Radial sectional areas can differ between seals of the seal pairs. Further, the first set of seals can be coupled to the second set of seals such that the first and second sets of seals are energized by the same setting motion of the actuation sleeve.
