Abstract
The present disclosure describes systems and methods for setting and sealing a plug in a casing within a downhole bore. This includes deploying into the casing a plug assembly comprising a tubular metal seal and deploying into the casing a setting tool. The tubular metal seal can be expanded radially to a first radial diameter with the setting tool by moving the setting tool longitudinally such that a tapered exterior portion of the first end of the setting tool engages a tapered interior portion of the first end of the tubular metal seal. The setting tool can then be removed from the casing. The method may comprise expanding the tubular metal seal radially to a second radial diameter by pumping fluid into the plug assembly such that the exterior of the tubular metal seal engages an interior of the casing.
