Claim:
1. A system for setting a plug in a well, the system comprising: a. a heater assembly, comprising an upper heater section and a lower heater section; the lower heater section comprising a heating element and having an outer surface, the upper heater section comprising an attachment assembly for engagement to a deployment system; b. a plug assembly, comprising an upper plug section and a lower plug section; the upper plug section comprising a plug body, the plug body defining a heater receiving cavity, the cavity having an inner surface and configured to receive and engage the lower heater section; c. the heater assembly mechanically engaging the plug assembly; whereby the plug assembly is movable with the heater assembly in a well bore; wherein the outer surface and the inner surface are in thermal contact, whereby heat from the heating element can be transferred to the body, heating the plug body; d. a eutectic alloy assembly comprising a eutectic alloy, the eutectic alloy assembly in thermal contact with the plug body, whereby heat from the plug body can be transferred to the eutectic alloy assembly, melting the eutectic alloy to form a down hole well plug sealing a well, the down hole well plug comprising the eutectic alloy and the lower plug section; and, e. the plug body shielding the heating element from contact with the eutectic alloy, whereby the lower heater section does not directly contact the eutectic alloy.
