| A composite sucker rod (12) has a tension rod (16) formed of a carbon fiber reinforced phenolic material and a support sleeve (18) formed of aluminum. The support sleeve (18) extends around the tension rod (16). A compressive preload is applied to the support sleeve (18) and a corresponding tensile preload is applied to the tension rod (16). The tensile preload reduces compressive loads applied to the tension rod (16). The compressive preload and the tensile preload are applied by differences in coefficients of thermal expansion of the materials from which the support sleeve (18) and the tension rod (16) are formed, and exposure to well temperatures. Opposite terminal end sections of the tension rod (16) have exterior peripheries (62) which are formed to define compound progressive radii provided having indentions (64) and protuberances (66) which fit in cooperative relation with formed surfaces of clamping members (34, 36) of end fittings (14) having profiles (38) to secure the end fittings to the tension rod (16). | ||||||

| 194 | Coated steel sucker rods and process for manufacture of same | US13985867 | 2012-02-16 | US09662823B2 | 2017-05-30 | Russel Moore; Jordan Moore |
| In a process for applying a friction-resistant coating to a steel sucker rod, the rod is passed, in sequence, through a surface preparation stage (for example, scale removal, shot peening, or other suitable method), an adhesive application stage (to enhance the strength of the coating's bond to the rod), an extrusion stage (in which the rod is passed through a die in conjunction with a flow of melted polymeric coating material), and a cooling (coating solidification) stage. Typically, the radial thickness of the coating will be between 0.125 and 0.375 inches. The process is adaptable to apply extruded coatings to continuous rod or to individual sucker rods having upset ends. The coating may be selected from but is not limited to high-density polyethylene, cross-linked polyethylene, polyvinylidene fluoride, ethylene tetrafluoroethylene, polytetrafluoroethylene, polyphenylensulfide, nylon, polyester, polyethersulfone, polyethylene terephthalate, polypropylene, polystyrene, epoxy, or acetyl. | ||||||
| 195 | METHODS FOR REPLACING PIN ENDS AND REPAIRING COATINGS ON COATED CONTINUOUS SUCKER RODS | US15122136 | 2014-02-28 | US20160369572A1 | 2016-12-22 | Russel Moore |
| In a method for repairing a fractured coated continuous sucker rod, the pin end segment of the broken rod is discarded, the remaining rod is cut off, and the existing rod coating is trimmed back from the rod cut-off point. A replacement pin end, incorporating a rod portion and an upset pin end, is welded to the cut-off end of the sucker rod. A resilient cylindrical repair sleeve with a longitudinal slit is spread open and urged by radial force over and around the rod portion of the replacement pin end and the adjoining exposed portion of the sucker rod. Using an appropriate fusing apparatus, the edges of the repair sleeve's longitudinal slit are then fused together, and one end of the sleeve is circumferentially fused to the trimmed-back existing coating. Repair sleeves can also be used to repair damaged sections of coating on unfractured sucker rods. | ||||||

| An artificial lift system for a well having a wellhead reciprocates a rod string with an uphole pump unit at the wellhead to operate a downhole pump unit in the well and lift fluid in the well. A rod segment coupled to the rod string at the wellhead has first opposing surfaces facing in first opposing directions. Opposing catchers are movable laterally relative to the rod segment at the wellhead. Each of the catchers has a face with second opposing surfaces facing in second opposing directions opposite to the first opposing directions. The catchers moved in a first condition have the second opposing surfaces disengaged from the first opposing surfaces of the rod segment, but the catchers moved in a second condition have the second opposing surfaces engaged with the segment's first opposing surfaces to hold the rod string in place. | ||||||
| 198 | Sucker rod guide | US13964942 | 2013-08-12 | US09200489B1 | 2015-12-01 | John F. Mabry |
| An oil well sucker rod guide protects the rods and production tubing from frictional wear during the vertical reciprocation pumping action. The guide has a sleeve enveloping the sucker rod with raised ribs contacting the tubing in an opposed fashion. The raised ribs are circumferentially sequenced to contact the entire circumference of the tubing and provide oil flow-through passages between the sleeve and the tubing. The raised ribs have side and inside end walls angled and contoured to increase through-put of oil in the tubing. | ||||||
| 199 | Rod guide and solids control assembly | US13310143 | 2011-12-02 | US09163483B2 | 2015-10-20 | Michael Brent Ford |
| The rod guide and solids control assembly can be mounted on a rod string. The assembly can allow well fluid that contains high solids to pass through the pump under normal operation while eliminating the solids from being swept back into the pump barrel. The assembly can include a body portion coupled to a bristle that extends helically around the body portion. The body portion can be placed on a pump valve rod or hollow valve rod. On an upstroke, the bristles can be locked into place for trapping and lifting the solids. On a downstroke, the bristles can be rotated for leaving the solids higher and away from a pump intake. This can allow the solids to be lifted out of the pump and thereby prevent solids from collecting on a bottom portion of the pump. Multiple assemblies can be incorporated into the sucker rod string. | ||||||
