  • Patent number: 10233926
    Abstract: The present invention recites a method of fabricating a stator for a downhole motor, the method comprising the steps of providing a stator tube having an interior surface and applying a bonding agent to the interior surface of the stator tube. Additionally, a mandrel is positioned within the stator tube, the mandrel having an outer geometry that is complimentary to a desired inner geometry for the stator. Furthermore, a reinforcing material is introduced into the stator tube to fill space between the mandrel and the interior surface of the stator tube and subsequently solidified to bond the reinforcing material to the interior surface of the stator tube. The mandrel is then removed from the bonded stator tube and reinforcing material such that a stator is fabricated.

  • Patent number: 9540545
    Abstract: Methods for improving adhesion or bonding between materials used in forming components of directional drilling assemblies, such as rotors and stators, are provided. A surface of a component may be treated, such as through cleaning, etching and/or activating a surface. The use of plasma treatment may enhance the adhesion between the surfaces and/or materials to be bonded, thereby reducing the degradation or mechanical failure of these materials in oilfield applications.

  • Patent number: 8444901
    Abstract: The present application discloses a progressive cavity motor or pump component, either stator or rotor, which provides a high glass transition temperature polymeric surface on the component which becomes resilient at or below the expected operating temperature of the motor or pump, but which remains solid at ambient temperatures, along with a method of fabricating either a stator or a rotor with such surface characteristics. Since the surface becomes resilient, the progressive cavity pump operates efficiently at temperatures above the glass transition temperature of the selected polymeric surface.

  • Publication number: 20120102738
    Abstract: A progressing cavity rotor facilitates pumping applications in progressing cavity pumping systems by ensuring a desired shape of the rotor. A resilient layer is placed over a rotor core to create a composite progressing cavity pump system rotor. Generally, the rotor core is formed from a harder material, such as a metallic material. Additionally, the composite rotor is placed in a mold and subjected to a molding treatment designed to enhance bonding of the resilient layer and formation of a desired exterior surface shape of the resilient layer.
