  • Patent number: 9732599
    Abstract: A multi-tasking downhole rod guide for centralizing a downhole pump rod within a production tubing string, while simultaneously reducing abrasion and deterioration of the production tubing and affording a built-in backflow preventer. The rod guide is configured with an elongate helix having a continuous trough-like channel through which hydrocarbons flow upwardly under high pressure. As the pressurized hydrocarbons flow through a succession of plates at each equidistant helical level, the elongate helix rotates synchronously with the upwardly flowing hydrocarbons within the production tubing string. Integrated bearing assembly and backflow An integrated bearings assembly and backflow restrictor accommodate hydrocarbons flow perturbations and sustain continuous fluid flow uphole.

  • Patent number: 8967247
    Abstract: A multi-tasking downhole rod guide for centralizing a downhole pump rod production tubing within production tubing, while simultaneously reducing abrasion and deterioration of the production tubing and engendering auxiliary pump-boosting functions. The rod guide is configured with an elongate helix having a continuous trough-like channel through which hydrocarbons flow upwardly under high pressure. As the pressurized hydrocarbons flow through a succession of plates at each equidistant helical level, the elongate helix rotates synchronously with the upwardly flowing hydrocarbons within the production tubing string.

  • Publication number: 20120186807
    Abstract: A multi-tasking downhole rod guide for centralizing a downhole pump rod production tubing within production tubing, while simultaneously reducing abrasion and deterioration of the production tubing and engendering auxiliary pump-boosting functions—with minimal energy consumption. The rod guide is configured with an elongate helix having a continuous trough-like channel through hydrocarbons flow upwardly under high pressure. As the pressurized hydrocarbons flow through a succession of plates at each equidistant helical level, the elongate helix rotates synchronously with the upwardly flowing hydrocarbons within the production tubing string. A multi-tasking downhole rod guide for centralizing downhole production tubing within a well casing, while simultaneously reducing abrasion and deterioration of the tubing and engendering auxiliary pump-boosting functions—with minimal energy consumption.
