Rahul Nandkumar Jadhav has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11851605
    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.
    Type: Grant

  • Patent number: 11208867
    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.
