Abstract: A rod guide 10 for positioning on a sucker rod includes a sleeve-shaped guide body 12 and two or more spiraling vanes 14, 16 each extending radially outward from the sleeve-shaped body, with each vane spiraling about the body and defining a flow path between circumferentially spaced vanes. Each vane has a forward portion 24 spiraling in a forward direction, and a backward portion 26 spiraling in a backward direction rotatably opposite the forward direction. The rod guide may be used for either reciprocating rod or rotating rod applications.

Abstract: A field-installable rod guide for a rod moveable within an oilfield tubular having an interior tubular surface for driving a downhole pump to pump liquids to the surface through the oilfield tubular. The rod guide comprises a body including interfitting body members. An outer tapered surface on one body member is engaged by an inner taper-engagement surface on the other body member, to urge the body members toward a rod gripping position about the rod. The mechanism disclosed provides a particularly strong engagement with the rod, so that the rod guide may be used for either reciprocating or rotating rods. For rotating type rod guides, an outer sleeve may be included about the body.
