A pump jack system for vertically reciprocating a downhole pump in an oil and gas well. The pump jack system includes a cylinder assembly having a drive cylinder and two balance cylinders. A piston in the drive cylinder may be used to provide an upstroke of a sucker rod string of a downhole pump. The pistons in the balance cylinders may be used to provide a downstroke of the sucker rod string. Lower chambers in the balance cylinders counterbalance the lifting and lowering of the piston in the drive cylinder. The pump jack system also includes an accumulator for maintaining a relative constant fluid pressure in the lower chambers of the balance cylinders.

Pump jack system and method

The present disclosure provides techniques and methods of tripping rods and tubulars. Specifically, the disclosure provides techniques for pulling a rod string out of hole and delivering the pulled out rod segments into a rod storage and racking system. The disclosure also provides techniques for pulling a tubular string out of hole and delivering the pulled out tubular segments into a tubular storage and racking system. The disclosure further provides techniques for delivering rods from the rod storage and racking system and running the rods down-hole. The disclosure also provides techniques for delivering tubulars from the tubular storage and racking system and running the tubulars down-hole.

Methods of mechanized and automated tripping of rods and tubulars

The present disclosure provides a tong system which includes a tong assembly and at least one string gripping device. The tong assembly is configured to engage a rod or tubular string at the junction between a first rod or tubular and a second rod or tubular of a rod or tubular string and unthread the first rod or tubular from the second rod or tubular. The tong assembly can also thread the first rod or tubular onto the rod or tubular string. The string gripping device is configured to hold a tubular string for at least a portion of the time. The tong system further holds the rod or tubular string against torque applied onto the first rod or tubular by the tong assembly.

Tong system for tripping rods and tubulars

The present disclosure includes a racking system for receiving, storing, and/or delivering rods and tubulars. The racking system includes a rack having a plurality of beams configured to support a plurality of rods, a plurality of tubulars, or both. each of the plurality of beams includes a proximal end and a distal end. The racking system further includes a plurality of indexers aligned with or proximal to the proximal ends of the plurality of base beams, wherein each of the plurality of indexers includes a series of rotating holders configured to transport the plurality of rods, tubulars, or both to and from the rack. Additionally, the racking system further includes a jack coupled to the distal end each of the plurality of base beams, wherein the jack raises and lowers the distal end of the base beam in relation to the proximal end.

Rod and tubular racking system

The present disclosure provides a well service rig for tripping rods and tubulars. The well service rig includes a service rig base unit, a mast coupled to the well service rig base unit movable between a folded position and an upright position, a vertical guide mounted to the mast, and a traveling block system coupled to the vertical guide at a first end and configured to travel up and down at least a portion of a length of the vertical guide. The traveling block system is couplable to a rod, a tubular, or both at a second end.

Mechanized and automated well service rig

The present disclosure provides a catwalk system. The catwalk system includes a base unit and a carriage disposed on the base unit and coupled to the base unit at one end and extends towards an opposite end of the base unit. The carriage is movable between a horizontal position and a sloped position, and between an extended position and a retracted position. The catwalk system further includes a racking system coupled to one or both sides of the base unit. The racking system includes a plurality of racking layers configured to store and support a plurality of rods and/or tubulars.

Mechanized and automated catwalk system

A well service rig system includes a well service rig, a catwalk, a racking system, and a tong system. The well service rig system provides techniques for tripping rods and/or tubulars with improved efficiency, such as reducing the need for operator intervention by providing process automation. The well service rig system is further adaptable for use with rods, tubulars, or both. The well servicing rig system also provides rod and/or tubular storage and delivery solutions via the integrated racking system. Furthermore, the present disclosure provides improved methods for tripping rods and/or tubulars.
