US Patent 11421505 Wellbore packer with expandable metal elements

A wellbore packer system includes a mandrel positionable within a wellbore. The system further includes a wellbore packer positionable around the mandrel. The wellbore packer includes an expandable metal sealing element positionable around a first portion of the mandrel to form a long-term seal within the wellbore in response to exposure of the expandable metal sealing element to wellbore fluid. Additionally, the wellbore packer includes an elastomeric sealing element positionable around a second portion of the mandrel to form a short-term seal in response to receiving a seal-setting force. Moreover, the wellbore packer includes a setting piston positionable to apply the seal-setting force on the elastomeric sealing element.
