Abstract: A pump jack controller is provided that can harness the potential energy generated during the operation of one pump jack amongst a plurality of pump jacks located at a well site and convert that potential energy into electrical energy that can be used to provide electrical power generated by the pump jack to power the other pump jacks located at the well site.

Abstract: A pump jack controller is provided that can harness the waste energy generated during the operation of a pump jack when its electrical motor is in an over-speed condition, and convert that waste energy into electrical energy that can be supplied back onto an electrical power grid thus converting the pump jack into a micro electric power generator.

Abstract: A sucker rod terminus assembly is provided for use in downhole wells. The sucker rod terminus assembly includes a plurality of parallel composite strands forming an elongate rod and a metallic terminus fitting. The terminus fitting has a cavity with a proximal opening to receive the rod end. The cavity includes a plurality of frustum shaped chambers. Preferably, the frustum shaped chambers have different sizes or shapes wherein at least a frustum chamber's proximal end diameter, distal end diameter, or length is different than an adjacent frustum chamber's proximal end diameter, distal end diameter, or length. Even more preferably, each frustum chamber is diametrically larger than the frustum chamber positioned proximally to it. Preferably, the sucker rod assembly further includes a spreader plate, preferably made up of a plurality of pieces and a hardened material to affix the rod to the terminus fitting.

Abstract: A stripper for stripping coating off of coated sucker rod is provided. The stripper can have a frame having spaced-apart and opposing end plates with a passageway for receiving the coated rod. Rollers located in the frame guide the coated rod as it passes through the passageway. A cutting bar contacts the coated rod to cut a strip off of the coated rod, leaving a remainder of coating that can be deflected off of the coated rod by a deflector as the coated rod passes through the stripper.
