Abstract: A method of treating a subterranean formation via well bore may include introducing a plurality of particles into the subterranean formation via the well bore, each particle having a substrate and a layer of cement on the substrate. The cement may be in a state of suspended hydration and the method may include introducing moisture to the subterranean formation via the well bore. The method may also include allowing the particles and the moisture to contact one another. Contact between the particles and the moisture may cause the cement to move from a state of suspended hydration to a state of secondary hydration.

Abstract: Migration of formation solids in a wellbore is restrained by feeding a slurry, comprising water, a viscosifier, and a concentration of cement clinker particles, into the wellbore, and hydrating the clinker particles in the wellbore. The clinker particles are kept in suspension during the hydrating, and upon completion of the hydrating the hydrated clinker particles form a hardened cement consisting of a permeable structure of interconnected hydrated clinker particles. A layer of degradable lost circulation material (LCM) may be employed to separate the slurry with clinker particles from the formation surrounding the wellbore during hydrating of the clinker particles.

Abstract: A method of treating a subterranean formation may include preparing a mortar slurry, injecting the mortar slurry into the subterranean formation at a pressure sufficient to create a fracture in the subterranean formation, and allowing the mortar slurry to set, forming a mortar in the fracture. The mortar slurry may be designed to form a pervious mortar, to crack under fracture closure pressure, or both.
