Abstract:
A method to provide support within a wellbore includes underreaming a section of the wellbore at a depth spanning a layer of an unstable formation. The method also includes deploying a bistable structure within the wellbore at the depth of the layer of the unstable formation. Additionally, the method includes actuating an expandable packer within the bistable structure to expand the bistable structure in a radially outward direction from a longitudinal axis of the bistable structure. The bistable structure is in contact with walls of the underreamed section of the wellbore upon expanding in the radially outward direction.
