Abstract: Described herein are embodiments of systems, apparatuses, and methods that include a center rod plunger, wherein movement and/or placement of the center rod is at least partially controlled by the center rod including a centering section that keeps the center rod more centered in the center rod plunger's housing. The center rod plunger may also include a clutch for retarding movement of the center rod in the housing. In still other embodiments, the center rod may have a shaft whose diameter may vary and a clutch that may include a one-piece device.

Abstract: Described herein are embodiments of systems, apparatuses, and methods that include a center rod plunger, wherein movement of the center rod between an open and a closed position is at least partially controlled by a clutch. The center rod has a shaft whose diameter may vary such that the clutch imparts a corresponding varying degree of friction on the center rod and such that less friction is imparted when the center rod is in its open and/or closed position.

Abstract: Described herein are embodiments of an improved bypass lubricator. The lubricator may include a body having a bore, where the bore may include at least an upper exit bore and a lower exit bore. The lubricator may also include an exit flow path that also has a bore, wherein the bore of the exit flow path is in fluid communication with the upper exit bore, the lower exit bore, and an exit valve. The upper exit bore and the lower exit bore may be sized relative to one another to create a pressure differential between the upper and lower exit bores to assist in maintaining an artificial lift device in the lubricator’s body. Shutting the exit valve shuts in the well.
