KUDU Sucker Rod Centralizer

Eliminate rod coupling wear with a nonrotating sleeve design

Eliminate rod coupling wear with KUDU sucker rod centralizers, which feature a nonrotating sleeve design tapered for rod tripping. The centralizers reduce torque in deviated wells, lower workover frequency, and reduce or eliminate rotational rubbing and rod wear.

In abrasive conditions, Schlumberger recommends centralizing the sucker rodstring wherever the coupling or tubing loading exceeds 25 lbm [11 kg]. In nonabrasive conditions, Schlumberger recommends centralizing wherever the loading exceeds 50 lbm [23 kg]. The centralizers should be installed to keep the loading below 100 lbm [45 kg] on each centralizer.
