A method of repairing wellbores includes setting a plug to isolate a wellbore flowpath within a plurality of concentric casing strings, milling a window through a radially innermost casing string of the plurality of concentric casing strings, via a casing milling tool, and radially outward towards one of a plurality of cement columns, cleaning out one of plurality of a cement columns between two of the concentric casing strings to expand the window radially, inserting a solid eutectic alloy into the wellbore flowpath above the plug, heating the solid eutectic alloy, via a heater inserted within the wellbore flowpath, to melt the eutectic alloy and allow the melted eutectic alloy to flow into the window, solidifying the melted eutectic alloy to form a solidified eutectic plug within the window, and drilling out the solidified eutectic plug to restore the wellbore flowpath through the eutectic plug.

Eutectic alloy system for concentric casing string cement repair

A system includes a control system disposed on a well surface and a pipe component disposed in a wellbore to form an annulus that is in fluid communication with a reservoir. The system includes a valve in fluid communication with the annulus. The system includes a recorder configured to detect data of the annulus. The system includes a fluid conduit configured to flow annular fluid from one or more annuli disposed in the wellbore. The fluid conduit is in fluid communication with the annulus, the valve, and a relief tank. The system includes a communication cable coupled to the control system, the valve, and the recorder. The recorder is configured to transmit the data to the control system.
