Abstract
An expandable downhole device may be used for supporting a wellbore and as a flow/sand control device. The expandable downhole device is initially RIH in a compressed state. Once the expandable downhole device reaches a predetermined depth in the wellbore, the expandable downhole device is transitioned from the compressed state to an expanded state to support the wellbore from collapsing. In the expanded state, an activation chamber of the expandable downhole device is expanded from a collapsed state to press an outer shroud of the expandable downhole device against the wellbore. A shape memory foam of the expandable downhole device is also expanded and hardens in the expanded state. The shape memory foam acts as a support layer for the activation chamber to provide additional support for the wellbore. The shape memory foam may be a porous material to be a filter media of the expandable downhole device.
