Abstract
The present invention relates to downhole tool assemblies (50) for use in deploying an alloy plug (61) or seal within a target region of an oil/gas well and clearing/removing well structures from said target regions. The assemblies are provided with a gas-generating chemical heating mixture (58, 59, 60). The heat generated by the chemical heating mixture is employed in heating a downhole target region, while the gas generated is harness to actuate the operation of one or more functional components (54) provided on the assembly to achieve the assembly's particular down-hole operation.
