Ribbon rod is Continuous Carbon Fiber Sucker Rod which is in the configuration of a reelable "tape" or "ribbon" with current dimensions of 1.45 in. x .212 in. It can be wound on a 10 ft diameter reel, 6 in. wide. It is designed to be run with some steel rods on the bottom similar to fiberglass rods. Its performance can be designed and analyzed using wave equation type mathematical models. Ribbon rod has been successfully tested in the lab and field over the past ten years. It was conceived as a method requiring no couplings, using a corrosion resistant, light weight material. Recent material/construction/design modifications and lab plus field trials reported here, have resulted in a system that can extend beam pumping to production rates beyond that currently possible with beam pump systems using other rod alternatives.
