Abstract: An anchor catcher tool can support tubing in casing. The tool is a slimline tool that can be set and unset with a partial (quarter) turn of a mandrel using a setting mechanism, such as a J-slot and pin arrangement. Uphole and downhole cages of the tool carry opposing slips. When set, the slips engage opposing cone faces to wedge against the casing and prevent movement of the tool. Excluded gas can flow up the annulus to the surface through aligned longitudinal flow paths on the exterior of the tool's components. To do this, a sleeve floating on the mandrel has the cone faces thereon and is longitudinally engaged with cages, which float on the mandrel and carry the slips. The sleeve keeps longitudinal channels on the cages and longitudinal divisions of the cone faces aligned with one another to produce the flow paths for annular flow.

Abstract: A downhole pump used for a reciprocating pump system includes a barrel and a plunger. The barrel couples to a tubing string and has a standing valve. The plunger couples to a rod string and has a traveling valve. One or both of the valves can include an assembly comprising a housing, an insert, a ball, and a seat. The insert allowing for flow therethrough defines a ball stop at one end has a ball passage at the other end. The insert positions in flow passage of the housing, and one of the ends engages a shoulder in the passage. The insert is secured in the flow passage with metallic material metallurgically affixed between at least a portion of the insert and the flow passage. For example, brazing material can be brazed at the end of the insert to metallurgically affix the insert in the passage. The ball is positioned in the insert, and the seat is positioned adjacent an end of the insert. The assembly is then incorporated into components of the pump.

Abstract: A downhole pump used for a reciprocating pump system includes a barrel coupling to a tubing string and having a standing valve and includes a plunger coupling to a rod string and having a traveling valve. One or both of the valves can include an assembly comprising a housing, an insert, a ball, and a seat. The insert allowing for flow therethrough defines a ball stop at one end has a ball passage at the other end. The insert positions in flow passage of the housing, and one of the ends engages a shoulder in the passage. The insert includes sidewalls and a conical body to reduce turbulence, flow velocity, gas breakout, ball chatter, and the like.

Abstract: A liner assembly is used for a polished rod of a reciprocating pump movable through a stuffing box. A liner sleeve positions on the polished rod and has an external thread on its distal ends. Roots of the external thread increase in depth in the external circumferential surface along the length toward the distal end. A nut positions on the polished rod and has internal thread configured to thread to the external thread of the liner sleeve. A head positions on the polished rod. The head is configured to engage the polished (e.g., with clamping or fastening), and the head is configured to affix to the nut (e.g., with thread or with flanges and fasteners). A gasket positions on the polished rod between the nut and the head. The gasket is held between a nose of the nut and a smooth bore relief of the head or is held between reliefs on the nut and head.

Abstract: A downhole pump is used for a reciprocating pump system having a rod string disposed in a tubing string. A barrel of the pump is disposed, and a plunger of the pump coupled to the rod string is movably disposed in the barrel. The plunger has an external surface disposed at an annular gap relative to the barrel's internal surface. The external surface has circumferential grooves defined thereabout that hold wipers. An inner ring of the wipers composed of a swellable material is engaged in the one or more circumferential grooves, while an outer ring composed of a second material is disposed about the inner ring. The swellable material of the inner ring energizes the outer ring in slideable engagement with the internal surface of the barrel.

Abstract: A sucker rod assembly for use downhole includes sucker rods and couplings. The sucker rods having pin connections with a pin face and a threaded pin. The coupling make up adjoining rods using box connections each having a box face and internal thread. Dry film lubrication is applied only to the internal thread of the couplings and excluded from the box face of the box connections. During make up, the dry film lubrication can help prevent seizing and/or galling of the threads for the connection between the coupling and the rods. The box connection is circumferentially displaced relative to the pin connection to place a preload on the pin, and the box face has a friction abutment with the pin face.

Abstract: A downhole pump for a reciprocating rod system in a deviated well has a barrel, a plunger, and at least one joint. The plunger is reciprocally moved in the barrel to lift fluid in the well. The barrel has a first valve allowing/restricting fluid passage into/out of the barrel, and the plunger has a second valve allowing/restricting fluid passage into/out of an interior of the plunger. The plunger has a plurality of plunger portions arranged longitudinally. The at least one joint longitudinally interconnects at least two of the plunger portions together. The at least one joint provides fluid communication between portions of the interior of the at least two plunger portions and allows lateral displacement between the at least two plunger portions relative to one another.
