Abstract
The present invention provides a tool assembly system for use in a single trip downhole operation in which an alloy plug/seal is set and then at least partially milled through. The system comprises a tubular chemical heater with a mill that has at least one flow port and a tubular mandrel arranged on the outside of the heater at up-hole and down-holes ends of the heater respectively and whereby the heater is removably retained within the mandrel so that the mill can be subsequently repositioned to work on the mandrel once the alloy plug/seal has been formed. The present invention also provides an associated method of forming an alloy plug/seal and milling it at least partially through in a single trip.
