ABSTRACT:
A well casing packer includes a seal mechanism, mounted on a mandrel. The casing packer comprises a seal element and a wedge member for driving the seal element radially outward against a well casing by applying radial forces to the seal element. This wedge member and a support member support the seal element to maintain the radial forces on the seal element, and the support member and the wedge member are constrained to move together during the driving of the seal element against the well casing. The casing packer also includes a mechanism for releasing the radial forces on the seal element, which comprises a member for releasing the constraint between the wedge and support members to allow these members to be longitudinally driven relative to one another to remove the support on the seal element by the wedge member, and thereby release the radial forces on the seal.
