A drop-in insert for a valve cage is adapted for use with a subsurface pump. The insert can be positioned in a valve cage housing. The insert includes a cradle, a base, a plurality of angled ribs, and an upper ring. In one embodiment, the insert may also include an extended nose region. Upper ring can abut an interior diameter of the housing, providing a smooth transition for pumped fluid, thereby decreasing turbulent fluid flow and promoting improved fluid flow during pumping operations. The insert can be dropped into position in the housing. Alternatively, the insert can be positioned in the housing by an interference fit or the like. The housing and insert can be part of a valve cage assembly that includes a ball, seat, seat plug, and end cap. The assembly may include an O-ring component which can cushion the insert, thereby prolonging the life of the insert.

A roller coupling apparatus for securing rods and other threaded components together in a pumping system. The roller coupling apparatus can include a body with a plurality of radially-positioned wheels rotatably coupled to the body. The arrangement of the wheels can uniformly spread the rod load within the interior diameter of the tubing. The body can include flat outer surfaces to facilitate increased fluid flow capacity around the apparatus. In operation, the wheels contact and roll along the interior diameter of the tubing, preventing surface-to-surface wear of the coupling body exterior and tubing interior, thereby prolonging coupling and tubing life. In one embodiment, the wheels can include wear grooves that can indicate wear areas in the wellbore. In one embodiment, the body can include grooves to permit retrieval of the apparatus when needed. Multiple apparatuses can be utilized to form rod strings of various lengths.

A rod centralizer and solids control assembly can be mounted on a rod string. The assembly allows well fluid containing high solids to pass through the pump while eliminating the solids from being swept back into the pump barrel or accumulating in the tubing. The assembly can include a body portion coupled to a bristle positioned helically around the body portion. The bristle can be coupled to a piston, allowing the bristle to extend during upward fluid movement and retract when rod rotation stops. The bristle can trap solids, leaving the solids higher and away from a pump intake. This can allow the solids to be lifted out of the pump, preventing solids from collecting on a bottom portion of the pump or tubing. The assembly can include centralizer components that center the rod, preventing it from rubbing against the tubing. Multiple assemblies can be incorporated into the rod string.

A modular shelf system having spaced apart upright subassemblies that each include multiple recesses conductive support standards, which are configured for receiving a low voltage current and illuminating the LED arrays of shelf fixtures that span adjacent upright subassemblies.

Low voltage modular shelf system

The present application provides, in one embodiment, a modular shelf system having spaced apart upright subassemblies that each include a first and second removable support standard recessed within. The system further provides at least one shelf fixture configured to be removably mounted to at least one of the support standards in each of a first and second upright subassemblies selected. The shelf may receive retail product trays via snap-fit fasteners. And, a variably configurable hanger bar may support the modular shelf system.

A jointed plunger assembly has a north end cap, a south end cap, and a body therebetween. The body includes at least one joint segment. In one embodiment, multiple joint segments are provided. Joints are formed throughout the body. In one embodiment, a flex rod is positioned in the north end cap, south end cap, and body. The flex rod is configured to flex and also seal fluid within the assembly, thereby preventing fluid leakage and helping to ensure that pumped fluid is moved upward and away from the pump. The assembly is configured to flex at each joint and is capable of flexing in various directions to follow the contours of the wellbore and the pump barrel. This configuration provides increased efficiency for deviated and horizontal pumping operations and helps the assembly components to wear more evenly, extending plunger life.

A roller coupling apparatus for securing rods and other threaded components together in a pumping system. The roller coupling apparatus can include a body with a plurality of radially-positioned wheels rotatably coupled to the body. The arrangement of the wheels can uniformly spread the rod load within the interior diameter of the tubing. In operation, the wheels contact and roll along the interior diameter of the tubing, preventing surface-to-surface wear of the coupling body exterior and tubing interior, thereby prolonging coupling and tubing life. In one embodiment, the wheels can include wear grooves that can indicate wear areas in the wellbore. Multiple apparatuses can be utilized to form rod strings of various lengths.

Tray fastener

A rotator apparatus for rotating a plunger, traveling barrel, valve rod, or sucker rod of a pumping system. The apparatus is adapted to be coupled to various downhole pump components and positioned within the wellbore. In one embodiment, the rotator apparatus includes a north coupling component, a piston, a cage, and a south coupling component. In an embodiment, the piston may include a plurality of flutes, which are formed so as to impart cyclonic rotation on fluids passing into the interior of the piston. On each downstroke and upstroke, the piston rotates an increment, causing the south coupling component and plunger, traveling barrel, valve rod, or sucker rod to rotate an increment. The rotation imparted on the plunger, traveling barrel, valve rod, or sucker rod redistributes the solids present in the fluid, preventing accumulation of the solids and constant wear in one particular area of the plunger and/or barrel.

Rotator apparatus and method therefor

A screen filter assembly and method for filtering solids within a pump barrel of a pump system. The screen filter assembly is incorporated into a full-length plunger, which contains a screen to filter solids from dirty production fluid. By filtering dirty production fluid, the screen filter assembly keeps the solids off of the plunger and away from the pump barrel.

Screen filter assembly and method therefor

A traveling valve assembly adapted to be coupled to a southern end of a pump plunger wherein the traveling valve has an elongated body and two ball valves, one positioned at the northern end of the traveling valve and another positioned at the southern end of the traveling valve. The traveling valve prevents pumped fluid that has slipped downwardly past the pump plunger from continuing to slip further down into the pump barrel. The traveling valve captures that pumped fluid that has slipped downwardly so that it may be produced upwardly through the pump.

Traveling valve assembly and method therefor

A screen filter assembly has an upper screen housing and a lower screen housing, both of which contain screens to filter solids from dirty production fluid. The lower screen housing has a plurality of circular grooves that trap solids therein, thereby helping to prevent the solids from falling downward toward the plunger. In an embodiment, the lower screen housing may include a plurality of rings that seal off the area between the upper screen housing and the lower screen housing, thereby preventing any cleaned fluid produced by the lower screen housing from mixing with any contaminated fluid above it. In another embodiment, a screen filter assembly is incorporated into a full-length plunger, which contains a screen to filter solids from dirty production fluid. By filtering dirty production fluid, the screen filter assembly keeps the solids off of the plunger and away from the pump barrel.

A dump valve assembly is disclosed. The dump valve assembly has a seat plug that couples to a southern end of a traveling valve, a standing valve, and a ball. The seat plug has two prongs with angled bottom edges that engage two corresponding slots within the standing valve and that lift the ball off of the standing valve in order to open the standing valve for pump drainage.
