ABSTRACT:
A method for controlling or terminating the flow of gas, oil or other fluids from an uncontrolled well penetrating a subterranean formation which comprises introducing into the active string metallic balls which melt at a temperature below that of the formation at the bottom end of the active casing or tubing string. Alternatively, liquid alloy is introduced into the active string which will cool and solidify in the well to form a plug of solid alloy in the string to stop the flow of fluid.
