Metal-based ceramic composite coatings and related devices, assemblies, and methods include monocrystalline superhard particles dispersed in a metal matrix disposed on at least one wear surface of a component of an oil and gas well assembly, system, or device.

An operating tool for an artificial lift system includes a housing having a key slot. The operating tool further includes at least one biasing member disposed in the housing. The operating tool further includes a key including a key head having a key profile, wherein the key head is remove from the slot when aligned with the key slot. The operating tool further includes a cam including a cam profile, wherein the cam is disposed in the housing and biased toward the slot by the at least one biasing member, wherein the cam profile is configured to engage the key profile to align the key head with the key slot.

A rod guide for guiding and protecting a sucker rod in a fluid mineral extraction setting. The rod guide comprising a bore shell, and a guide bore, a first end, a second end, one or more glue ports, a plurality of glue dams and a plurality of flutes. The bore shell wraps around the guide bore. The bore shell comprises an outside surface and an inside surface. The plurality of flutes are arranged around the bore shell extending outward from a central axis. The plurality of flutes are configured to prevent the sucker rod from rubbing within a tubing, as the sucker rod is inserted and withdrawn from said tubing the rod guide and the guide bore comprises the central axis.

A tubular engagement interface for interfacing the coupling of two movably engaged tubulars is disclosed. The tubular engagement interface includes a body. The body includes a body engagement surface. A polycrystalline diamond element is coupled with the body, and includes a diamond engagement surface. The tubular engagement interface may be coupled with an inner wall of a first tubular, such that the body engagement surface, the diamond engagement surface, or combinations thereof are engaged with an opposing engagement surface of an outer wall of a second tubular. Alternatively, the tubular engagement interface may be coupled with the outer wall of the second tubular, such that the body engagement surface, the diamond engagement surface, or combinations thereof are engaged with an opposing engagement surface of the inner wall of the first tubular.

Embodiments of the present invention disclose a standoff assembly for a sucker rod used for sucker rod pumps. The assembly includes an annulus body, a hole that passes through the annulus body, the hole configured to permit a sucker rod to translate through the hole, a sliding material component located along the surface of the hole, and a temporary component; wherein upon elimination of the temporary component, the sliding material component interacts with the sucker rod to reduce sliding friction as the sucker rod translates through the assembly.

A leveling assembly that is capable of lubrication without separating the individual leveling plates. The leveling assembly comprising: a first plate having a convex curved surface having a curvature, the first plate defining a central bore therethrough; a second plate having a concave curved surface shaped to mate with the convex curved surface; the second plate defining a central bore therethrough. One of the first or second plates defines a lubrication passageway extending from a first opening on an exterior surface thereof to a second opening on the curved surface, and a lubrication groove extending from the second opening to the central bore of the plate with the lubrication passageway.

A sucker rod guide having low friction and high wear resistance is disclosed herein, along with a fluid extraction system comprising the same. At least a part of the exterior surface of the sucker rod guide is formed from a cold worked and spinodally-hardenable or spinodally-hardened copper alloy comprising from about 5 to about 20 wt % nickel, and from about 5 to about 10 wt % tin, the remaining balance being copper, and having a 0.2% offset yield strength of at least 75 ksi. The guide includes a smoothbore adapted to surround and engage the surface of a sucker rod. The exterior surface of the guide can include grooves miming between the two ends. In particular embodiments, the guide is made by joining together two identical guide segments. In other embodiments, the guide is a single integral piece molded around a sucker rod.

A helical solid profile attached and originating from the outer diameter of a composite or steel sucker rod and extending approximately to the inner diameter of the production tubing, running axially along the sucker rod body and affixed to it for reinforcement and stabilization of the sucker rod tension member body in axial alignment to the central axis of the production tubing which the sucker rod member is housed in, whereas the helical solid profile is made of material which is for acceptable use within the production system environment, the helical solid profile purpose being to control and reduce the sucker rod's deflection during compressive moments, extending the life of the sucker rod or reduction in stress and erratic buckling cycles.

A synthetic metal system comprising a frame member comprising a cellular structure including a plurality of openings; and a matrix material comprising a polymeric material, wherein the matrix material is configured to at least partially penetrate one or more of the plurality of openings in the frame member such that the frame member is at least partially encased within the matrix material.

A mechanical rod rotator assembly comprising a mechanical rod rotator and an actuating mechanism for a mechanical pumping rod rotator, wherein the mechanism comprises a connecting arm and a guide member that slidably embraces the pumping rod, in order to allow a pivoting lever that is in connection with said connecting arm, to interact with the internal mechanism of the rod rotator to gradually rotate the pumping rod and thus avoid impartial wear caused by the constant up and down reciprocating movement of the same within the well, being in turn that the mechanism of the invention does not require special tools for its assembly and installation.
