ABSTRACT:
A continuous length of reinforced plastic ribbon rod is wound on a reel and replaces a conventional oil well sucker rod formed of long sections of steel rods. The reinforced plastic has a high modulus of elasticity, is sufficiently stiff for use in pumping, and has enough flexibility to be wound onto a reel or drum. The reel of ribbon rod is positioned above oil well tubing and the ribbon rod, with an oil pump attached to its free end, is fed into the tubing and lowered to the bottom of the well. The ribbon rod is secured to a surface pumping means, and reciprocating motion is transmitted to the oil pump through the ribbon rod.
