Abstract
A method of sealing a casing comprising the steps of deploying a thin wall tube in the region the casing is to be sealed, melting a low temperature alloy and allowing it to flow into the annulus between the thin wall tube and the casing, and allowing the low temperature alloy to solidify. The thin wall tube may include protrusions on its outer surface, of similar height so as to centralise the thin wall tube in the casing.
