Rod Guides
In a deviated or directional well, the sucker rod string contacts the inner wall of the production tubing under side loading. This contact causes tubing wear, rod wear, and ultimately tubing failures or rod parting — both costly to repair. Rod guides centralise the rod string inside the tubing, distributing contact loads and protecting both rod and tubing from abrasive wear.
Proxima supplies rod guides from ChampionX and Roller Rod Guides through Power Flow International Sales.
Why Rod Guides Matter in Deviated Wells
In a vertical well, the rod string hangs centrally in the tubing with minimal wall contact. In a deviated well — common in Azerbaijan’s mature fields — the rod string rests against the low side of the tubing at every dogleg. Each stroke cycles the rod across the contact point, grinding through the tubing wall over thousands of cycles per day.
Without rod guides, a moderately deviated well can develop tubing holes in under six months. Rod guides placed at regular intervals lift the rod string off the tubing wall, replacing sliding metal-on-metal contact with a rolling or centralised interface.
Product Range
Roller Rod Guides
Roller rod guides mount on the sucker rod body and carry rolling elements — typically wheels or rollers — that contact the tubing wall. The rolling action eliminates sliding friction, dramatically reducing wear on both tubing and rod. Suitable for moderate-to-high deviation angles and high stroke frequencies.
Supplied through Power Flow International Sales (Roller Rod Guides brand).
Centralising Rod Guides
Centralising guides are moulded polymer or steel bodies that clamp onto the rod and keep it centred in the tubing. They absorb side loads without the rolling mechanism, offering a lower-cost solution for wells with moderate deviation and lower production rates.
Supplied through ChampionX.

Why Source Through Proxima
Proxima’s application engineers review your well deviation survey and recommend guide spacing and type based on dogleg severity, rod size, and production rate. We supply guides in quantities matched to your rod string specification.
Frequently Asked Questions
Q: How often should rod guides be placed on a rod string?
Spacing depends on dogleg severity and rod size. Typically 1–3 guides per rod joint at high-dogleg intervals, with wider spacing in straighter sections. Proxima engineers calculate placement from your deviation survey.
Q: What is the difference between roller guides and centralising guides?
Roller guides carry rolling elements that eliminate sliding friction — best for high deviation and high stroke rates. Centralising guides are simpler and lower cost, suited to moderate deviation where friction is less critical.
Q: Do rod guides affect pump stroke efficiency?
Properly sized rod guides add minimal load to the rod string. The reduction in friction from tubing contact typically improves pump efficiency and reduces surface unit load compared to an unguided string in a deviated well.
Q: Can rod guides be used with coiled rod?
Rod guides are designed for jointed sucker rods. Coiled rod systems use a different approach to managing wall contact. Contact Proxima to discuss your specific configuration.
