Abstract
An inflatable packer contains a reactive metal in an annular space between the mandrel and the element. A fluid is admitted into the annular space to start a reaction that gives off gas. The generated gas fills the annular space and inflates the element in the process. The actuating fluid can be water and the off gas can be hydrogen. The volume of the reactants can also increase as they swell in the reaction that generates the gas. A valve arrangement associated with the mandrel retains the gas pressure and prevents over-pressurization. The packer can be set in a surrounding tubular or in open hole.
