Notes and Success Stories Deep below the Eiffel Tower in the Paris Basin of France, Wheeled Rod Guide Couplings are at Work. Wheeled Rod Guide Couplings are at work in Egypt, Pakistan, India, Canada, France, and the United States.  Wheeled Rod Guide Couplings are at work half-way between Long Beach and Catalina Island. Wheeled Rod Guide Couplings are working under an airport in Jena, Louisiana. Wheeled Rod Guide Coupling Success Stories (Wheeled rod guide couplings reduce sucker rod and tubing wear.)  Carter County, Oklahoma: This well was going down with tubing leaks every month. The operator installed 45  Wheeled Rod Guides at the wear points. The well has not been down in 6 months.  Crane County, Texas: This operator has been running Wheeled Rod Guides in a deviated well for 18 months.  There have been no tubing leaks and no rod breaks. Glacier County, Montana: This operator has been running Wheeled Rod Guides for two years. During this  time no tubing leaks have occurred and the well is still pumping. The wheels in the guides have been changed once.

Ector County, Texas: An operator has been running Wheeled Rod Guides in several of his wells for 18 months.  There have been no tubing leaks nor rod breaks. Two of the wells have been pulled within 18 months.  They showed only slight wear on the guide wheels. Finley County, Kansas: This operator had a well that was going down once a month. He installed 11  guides. Eighteen months later the well was pulled for a pump change. The operator only needed to  change 7 of the 44 wheels. Santa Barbara County, California: This operator was pumping a well on an offshore platform. It was  deviated 34 degrees at the bottom. The production engineer ran Wheeled Rod Guides that included  some 10' and 12' pony rods and 100 Wheeled Rod Guides. After five months he pulled the well for  inspection. There was no wear on the rods and the wheels on the guides had only 10% wear.
