Abstract
A downhole packer assembly may include an outer wall, an inflatable bladder, at least one coupling element, and at least one auto-retraction mechanism. The inflatable bladder may be configured to cause the outer wall to expand radially outwardly. The at least one coupling element may be mechanically coupled radially with the outer wall. The at least one auto-retraction mechanism may be configured to mechanically assist the outer wall to retract radially inwardly when the inflatable bladder is deflated from an inflated configuration toward a deflated configuration. The auto-retraction mechanism may include a chassis and a plurality of pistons, each piston having one end coupled to the chassis and another end coupled to a coupling element.
