Abstract
A packer system includes an expandable packer disposed on a casing. The expandable packer is formed from a metal, includes one or more expandable wall portions that expand in response to a threshold pressure that is greater than a predetermined maximum drilling pressure, and includes an ignition component that sparks a chemical powder to cause the one or more expandable wall portions to expand. A method includes disposing first and second expandable packers on a casing. One or more first expandable wall portions of the first expandable packer are urged to expand in response to a first threshold pressure. If the one or more first expandable wall portions do not expand, then one or more second expandable wall portions of the second expandable packer are caused to expand in response to a higher, second threshold pressure, via actuating an ignition component that sparks a chemical powder.
