Abstract: Suspensions of elastomer particles for cement compositions and associated methods of cementing. An example method includes providing a suspension of elastomer particles. The suspension of elastomer particles includes elastomer particles, an aqueous fluid, a viscosifier, a surfactant, and a clay-based stabilizer. The suspension may be combined with a cement slurry to form a cement composition. The cement slurry includes a cement and a base fluid. The cement composition may be introduced into a wellbore penetrating a subterranean formation. The cement composition may be allowed to set in the wellbore.

Abstract: A system for use in performing a reverse cementing operation in a downhole well operation and creating a sectional separation within a well casing and a process completion indicator. The system comprising a well casing, and a magnetic element, and a plurality of magnetizable particles. The magnetic element is coupled with a radial, interior section of the well casing and the plurality of magnetizable particles couple with the magnetic element forming an impediment between a first and second section of the well casing. The impediment creates a detectable resistive force. The magnetizable particles and the at least one magnet form a contiguous and porous wall and the resistive force creates a pressure spike at a surface of the well in response to the interaction of a cement slurry pumped into an annulus of a wellbore and the wall.
