A method for remediating fractures in a cement structure including heating the cement structure to a temperature at or above the melting temperature of the eutectic metal alloy particles to allow the particles to flow in liquid state into the fractures in the cement structure until the heat source is discontinued, allowing the particles to cool and solidify.

Eutectic metal alloy-containing cement and methods of use thereof

A fluid composition including a mixed metal oxide viscosifier, a clay viscosifier, and solid eutectic metal alloy particles. A method including pumping a drilling fluid downhole in a wellbore. The drilling fluid including water, a mixed metal oxide viscosifier, a clay viscosifier, and solid eutectic metal alloy particles. The method further including allowing the drilling fluid to reach a target zone with elevated permeability and forming a filter cake containing solid eutectic metal alloy particles in the target zone. The method including heating the filter cake to a temperature greater than the melting temperature of the eutectic metal alloy particles, allowing the particles to melt and become liquid eutectic metal alloy particles. The method including discontinuing heating and allowing the filter cake to cool to a temperature lower than the melting temperature of the solid eutectic metal alloy particles to produce a strengthened filter cake.

Eutectic metal alloy in drilling fluids and methods of use thereof

A eutectic metal alloy is placed through a coiled tubing into a wellbore formed in a subterranean formation. The eutectic metal alloy includes a mixture of multiple metals. The eutectic metal alloy has a melting temperature that is less than a melting temperature of each individual metal of the multiple metals making up the eutectic metal alloy. The eutectic metal alloy is heated to a temperature equal to or greater than the melting temperature of the eutectic metal alloy to liquefy the eutectic metal alloy. The liquefied eutectic metal alloy is flowed from the wellbore and into the subterranean formation, thereby exposing the liquefied eutectic metal alloy to a specified downhole temperature within the subterranean formation and causing the liquefied eutectic metal alloy to solidify to form a seal. The seal prevents fluid from flowing from the wellbore and into the subterranean formation.
