Abstract: 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.

Abstract: A precursor cement slurry includes a cement powder, water, and an additive. The additive includes a cement bond enhancer and a non-aqueous fluid additive. The non-aqueous fluid additive is an internal phase and the cement bond enhancer stabilizes the non-aqueous fluid additive in the form of a Pickering emulsion within the precursor cement slurry. The cement bond enhancer is comprised of the reaction product of graphene oxide with an anchoring functionality. A method of forming the precursor cement slurry and a method of cementing an annular space within a wellbore are also provided.

Abstract: A method of producing a nanosilica-containing cement formulation, the method comprising the steps of mixing an amount of a determinant nanosilica particle and a functional coating; applying a dynamic initiator to trigger a reversible reaction of the functional coating to produce a reversible cage, where the reversible cage surrounds the determinant nanosilica particle to produce an encapsulated nanosilica; and mixing the encapsulated nanosilica and a cement formulation to produce the nanosilica-containing cement formulation.
