Tubing failures due to rod wear results in high well maintenance costs and lost production. The CobaltSENSOR utilises Ensenium™ technology (Patented by COBALT) to detect sucker rod guide EWV wear indication and prevent premature rod-to-tubing wear and reduce costs per well.

The sucker rod has a history of nearly one hundred years. The first metal sucker rod patent (U.S.528168) in the United States by Samuel M. Jones in October 30, 1894.

In the past 40 years, many new materials and technical advances have been developed in the manufacturing of sucker rods, such as frequency induction, infrared temperature measurement, coupling production, advanced forging technology, rolling external threads, extrusion technology, friction welding, shot peening, surface induction quenching and other metallurgical engineering innovations.

Sucker Rod Guides have been around since the 1940's. Originally starting as a rod scraper, the first device applied to the rod body was a metal flat, tack-welded to the sucker rod in effort to scrape paraffin from the tubing and distribute rod side-loading across the tubing wall. Sucker Rod Guides have evolved primarily to polymer materials, injection molded directly onto the sucker rod for centralizing the sucker rod to prevent tubing wear.

COBALT Sucker Rod Guides and CobaltSENSOR offer a technological advancement not previously available since the first sucker rod was produced more than 100 years ago.
