Abstract
A method of sealing leaks in oil and gas wells includes: removing a portion of an inner casing string within a wellbore to access an annulus associated with an area of fluid leakage; filling a first portion of the annulus with a first metal alloy to form a first metal alloy layer; filling a second portion of the annulus with cement to form a cement layer over the first metal alloy layer; and filling a third portion of the annulus with a second metal alloy to form a second metal alloy layer over the cement layer. The first metal alloy layer, the cement layer, and the second metal alloy layer together seal the annulus.
