Claim 0:
1. A method of deploying a eutectic alloy based tool within a well, said method comprising:
providing a eutectic alloy based downhole tool comprising a tubular body with one or more eutectic alloy elements located on an outer surface thereof, each of the one or more eutectic alloy elements extending only partially around the outer surface of the tubular body, said tool having an outer diameter with a clearance from the inner diameter of the well, said tool further comprising an outer sleeve having insulating properties;
delivering the downhole tool to a target region within an oil/gas well where the tool is to be deployed;
running a tubular expanding tool through the interior of the tubular body so as to increase the outer diameter of the downhole tool and in so doing reduce the clearance between the eutectic alloy and the well;
positioning a heater within the tubular body proximal to the eutectic alloy and operating the heater to melt the eutectic alloy and pass the melted eutectic alloy through a focused outlet in the outer sleeve, the focused outlet provided by openings or weakened regions that form openings when in contact with the melted eutectic alloy; and
allowing the eutectic alloy to cool and resolidify so as to seal the tool in place within the target region of the well using the alloy.
