Abstract
A seal assembly usable with a well includes a seal ring that is adapted to expand radially inwardly and radially outwardly in response to being longitudinally compressed between a first energizing ring and a second energizing ring. The seal assembly may also include a first backup ring between the seal ring and the first energizing ring and a second backup ring between the seal ring and the second energizing ring.
