Abstract

A downhole seal assembly (10) for establishing a seal against a bore wall (13a) comprises a mandrel (14), a seal element (16) mounted on the mandrel (14), a setting support member (18) mounted on the mandrel (14), and at least one setting element (20) mounted on the mandrel (14) axially between the seal element (16) and the setting support member (16). Relative axial movement between the seal element (16) and the setting support member (18) over a first actuation distance causes the seal element (16) to be deflected radially outwardly by an axially adjacent setting element (20). Relative axial movement of the seal element (16) and the setting support member (18) over a subsequent actuation distance causes radial expansion of at least one setting element (20) to further expand the seal element (16).
