Roy R. Fleshman 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: 6700252
    Abstract: A modular electric motor for use in a wellbore. The modular motor includes a plurality of modular motor sections. The modular motor sections being mechanically and electrically coupleable. At least one modular motor section having a rotor. The rotor of one modular motor section having a rotor being drivingly coupleable to the rotor of a second modular motor section having a rotor. Thus, a given motor may be assembled to a variety of desired lengths by connecting the appropriate number of modular motor sections.

  • Patent number: 6698521
    Abstract: A system for removing solid particulates from a production fluid. The system includes a solid separator to remove the solid particulates from the production fluid to reduce pump component wear. The system is disposed in a wellbore such that wellbore fluids are drawn into the solids separator before entering the submersible pump. Solid particulates are separated from the fluid that flows through the solids separator before entering the submersible pump. The solid particulates are routed past the submersible pump. The solid particulates may be reinjected into the fluid discharged from the pump.

  • Patent number: 6357530
    Abstract: A system for producing production fluids from a wellbore while removing gas that collects in pockets within the wellbore. The system includes an electric submergible pumping unit. The unit includes a submergible pump powered by a submergible motor. The fluid discharged by the pump is forced through a pressure reduction device, such as a jet pump, to create a low pressure area. This low pressure area is coupled via a conduit to a gas pocket creation area within the wellbore. For example, gas pockets may develop beneath a packer disposed above the electric submergible pumping system. The low pressure area at the pressure reduction device draws the gas into the discharged production fluid and delivers the mixture to a collection at the earth's surface.
