Abstract
A sucker rod guide is used on a sucker rod within production tubing. The guide includes a sleeve having multiple vanes. The sleeve is designed to fit onto the sucker rod and includes ends, an outer surface, and a particular length and diameter along its axis. The vanes are evenly distributed about the sleeve and protrude outwardly to a defined diameter. Each vane exhibits symmetry along longitudinal and lateral axes, with distinct characteristics. Sidewalls at each end of each vane diverge from one another and extend to a midpoint of symmetry. Angled faces at each end of each vane extend at an angle from the sleeve's surface, and each vane has an external face that has a diamond shape. The guide is configured to reduce turbulence adjacent the sucker rod near the edge of the guide.
