Abstract
A variety of methods, systems, and apparatus are disclosed. In one example, a well tool is deployed downhole on a conveyance (e.g., tubing string) with the well tool in an open condition, wherein a flow path of the tool is in fluid communication with the tubing string. A swellable metallic material is arranged along the flow path. A service operation may be performed while the tool is in the open condition, including flowing a well fluid down the tubing string and through the flow path of the tool. After performing the service operation, an activation fluid may be delivered downhole to the well tool to activate the swellable metallic material to close the flow path of the tool.
