Abstract
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.
