Abstract
A downhole sealing tool and method use a swellable material (e.g., a swellable rubber or a swellable metallic material) with increased surface area for faster reaction with an activation fluid. In one example, a swellable metallic sealing element and actuator are carried on a tool mandrel for lowering into a wellbore on a conveyance. The sealing element includes a plurality of expandable metal wires supported along the tool mandrel. The expandable metal wires comprise a swellable metallic material that swells in response to exposure to an activation fluid. The actuator is used to separate at least a portion of the expandable metal wires, to increase a surface area exposed to the activation fluid and thereby accelerate the reaction.
