In deviated wells, guides or wheels properly placed on the rode string can prevent both wear on the tubing and the rods. Proper placement involves integrating information on hole trajectory, rod string properties, and economics. Too many guides or wheels will increase polished rod load, thereby increasing recovery cost. But two few guides or improper spacing of guides can either prevent rod and tubing wear nor lower polished rod load. Consequently, optimal rod guide spacing is required. The paper discusses a stress analysis, spacing and deflection, and optimal spacing.
