Systems and methods treat sucker rods in a machine through a multi-step process. Initially, sucker rods are cleaned before being conditioned. The conditioning process involves using a defined type and a defined size of media, applied at a first intensity to the rods using first media accelerators (first wheels with a specific diameter and rotational speed, and/or imparting a certain amount of media). The conditioned surfaces are then shot peened at a higher intensity using second media accelerators, which can have larger diameters, faster rotational speeds, and/or can impart a greater amount of media. Both the conditioning and shot peening processes involve reclaiming the media for reuse.

A sucker rod guide is used on a sucker rod within production tubing. The guide includes a sleeve having multiple vanes. The sleeve is designed to fit onto the sucker rod and includes ends, an outer surface, and a particular length and diameter along its axis. The vanes are evenly distributed about the sleeve and protrude outwardly to a defined diameter. Each vane exhibits symmetry along longitudinal and lateral axes, with distinct characteristics. Sidewalls at each end of each vane diverge from one another and extend to a midpoint of symmetry. Angled faces at each end of each vane extend at an angle from the sleeve's surface, and each vane has an external face that has a diamond shape. The guide is configured to reduce turbulence adjacent the sucker rod near the edge of the guide.

SYSTEM AND METHOD FOR INSTALLING TOOL FOR USE WITH ARTIFICIAL LIFT MANDREL
A system used with a gas lift valve on a tubing string in a borehole includes a mandrel assembly and a tool assembly. The mandrel assembly holds the gas lift valve disposed in communication between a through-bore and a borehole port. The mandrel assembly couples to the tubing string and defines a lock profile, an uphole seal bore profile, and a downhole seal bore profile. The tool assembly is configured to retrievably deploy in the tubing string. The tool assembly has a lock, an uphole seal, an auxiliary tool, and a downhole seal. The lock is releasably engageable with the lock profile, and the uphole and downhole seals are sealably engageable respectively with the seal bore profiles. The auxiliary tool, which can be a jet pump or a venturi device, has an annulus port that communicates with an annular area of the throughbore sealed by the uphole and downhole seals.
Identification and tracking of sucker rods, tubulars, and other threaded wellbore components uses a coded indicium or a distinctive marking adjacent threaded areas, such as on the pin ends of the endpieces for the sucker rods or on the counterbore of a tubular coupling. The coded indicium can be applied to a surface of an undercut area located on the pin end between a threaded area and a shoulder of the endpiece. The coded indicium is applied with a non-damaging process, such as laser annealing, laser marking, or another comparable technique. When the endpieces are connected together with a coupling, the coded indicium in the undercut area is covered by the coupling, which threads to the pin ends and engages the shoulder of the endpieces. Secondary tracking can also be achieved using an electronic device, such as an RFID device, disposed on a thread protector for the threaded wellbore component.

Used gas lift valves having a used bellows assembly are remanufactured. Separable components are disassembled, and the used bellows assembly is removed from a dome housing by de-brazing the used bellows at a brazed joint from a mating surface of the dome housing. A replacement bellows is then affixed (e.g., arc welded) to the dome housing's mating surface, and a bellows adapter is affixed (e.g., arc welded) to the replacement bellows. The separable components of the used valve are then reassembled to produce a remanufactured gas lift valve. The remanufactured valve has a replacement bellows composed of a nickel-chromium alloy as opposed to a nickel-copper alloy, has the replacement bellows arc-welded to the dome housing as opposed to being brazed thereto, and has the adapter arc-welded to the bellows as opposed to being brazed thereto.
