Abstract
A technique involves a packer formed as an expandable packer with an internal expandable bladder. The internal expandable bladder is surrounded with a plurality of packer slats oriented in a manner to enable expansion and contraction of the packer. Additional features are incorporated into the bladder and/or slats to facilitate repeated expansion and contraction of the packer while limiting leaks between wellbore regions and preventing extrusion of the bladder.
