A technique involves a packer formed as an expandable packer with an internal expandable bladder. The expandable bladder is formed with a section that is radially enlarged relative to an axial end of the expandable bladder when the bladder is in a relaxed state. The bladder configuration enables use of a reduced expansion ratio while still allowing expansion of the packer to a desired large diameter.

Expandable packer construction

A technique enables construction of a simplified inflatable packer. An inflatable packer is constructed with a packer reinforcement layer having at least one fiber layer. The fiber layers provide both mechanical and anti-extrusion qualities in a relatively simple and small package. Depending on the desired application, the inflatable packer also comprises an inner bladder layer and other potential layers, such as an outer seal layer. Mechanical extremities are used to secure longitudinal ends of the various packer layers, including the packer reinforcement layer.
