A downhole tool includes a tool body and an actuator coupled to and selectively extendible relative to the tool body. The actuator has a working face that contacts a downhole formation, and which includes an upper portion and a lower portion. The lower portion has a tapered surface that is directed radially inwardly and axially downwardly relative to the first portion, with at least a portion of the tapered surface including an ultrahard material having a different coefficient of friction as compared to a first material of the upper portion.

The present invention relates to a wireline cased-hole standoff (WCSO) for installation on a wireline cable of a wellbore logging tool. In embodiments, WCSO may be capable of significantly reducing wireline cable drag in a cased-hole section of a well or wellbore as well as reduce logging tensions and improve force transmission from wellbore surface to logging tool cable head during wireline logging operations. In one embodiment, WCSO comprises two cable insert halves, two opposing WCSO body halves (an upper body and a lower body), and two outer shells (an upper low-friction shell and a lower low-friction shell). Such components may be fastened together onto the wireline cable using screws, bolts, dowel pins, spigots, or any combinations thereof.

A wear support assembly includes a wear pad arranged on top of a support plate, wherein the support plate has a lower surface for connecting to a raise boring tool and both the wear pad and the support plate have at least one hole for receiving a bolt to connect the wear pad to the support plate. Also, a raise boring tool for raise boring operations includes a reamer head having a body, a plurality of roller cutters connected to the body using a holder, a nose or drive stem connected the body, and at least one wear support assembly, wherein each support plate is connected directly to the raise boring tool and each wear pad is radially or perpendicularly bolted to each support plate.

A hard facing is preferably accomplished with laser clad beads applied to horizontal directional drilling (HDD) component(s). These components may be subject to recirculating fluid regions associated to stepped geometries along a drill string, including various drill string coupling members. For example, laser cladding can be applied to a step region of the sonar housing and starter rod. A method applies a hard face coating such as laser cladding or other suitable hard facing in areas of tight geometric tolerances.

Various methods of hardbanding an apparatus are described. In one aspect of the invention an improved method of re-applying a hardbanding alloy to worn tool joints of a previously hardbanded drill pipe results in preservation of the metallurgical properties of the drill pipe and preservation of the internal polymer coating that lines the drill pipe. A method for applying hardbanding includes arc welding a consumable metal welding wire to a tool joint having a surface temperature that ranges from about 50° F. to about 170° F. and the arc welding power supply utilizes DC current. The method herein produces a hardbanded tool joint comprising a heat affected zone (HAZ) of a based metal having a Rockwell hardness of 40 Rc or less.

Layered coating applications for sensing telemetry are provided. An example method can include depositing an optical waveguide on an inner surface of a wellbore tool, the optical waveguide including a first layer of low refractive-index material, a second layer of high refractive-index material applied to a first surface of the first layer, and a third layer of low refractive-index material applied to a second surface of the second layer; configuring non-uniformities at one or more locations of the optical waveguide, the non-uniformities configured to reflect or scatter light at angles relative to a site of interaction between the light and the non-uniformities; determining a reflection and/or transmission pattern of light propagated through the optical waveguide and reflected or scattered by the non-uniformities; and based on the reflection and/or transmission pattern of the light, determining one or more conditions associated with of the wellbore tool.

A backup ring for a seal assembly including a body having a radially outer surface and a radially inner surface, an opening in the body extending from the radially outer surface toward the radially inner surface, the opening being receptive to a line to guide and protect the line. A wellbore system including a borehole in a subsurface formation, a string disposed in the borehole, a seal system disposed in the string, the system including a backup ring comprising a body having a radially outer surface and a radially inner surface and an opening in the body extending from the radially outer surface toward the radially inner surface, the opening being receptive to a line to guide and protect the line and a method for running a line along a seal system.

A textured surface of oil and gas equipment includes a first substrate, an antiwear coating, and a second substrate, and further includes a texture, where the texture includes a first texture and/or a second texture; the first substrate and the second substrate are capable of moving relative to each other when operating, the first texture is arranged on a surface of the first substrate that is in contact with the antiwear coating, the second texture is arranged on a surface of the antiwear coating that is in contact with the second substrate. A method for machining the textured surface of oil and gas equipment is provided, which improves various performances of the oil and gas equipment such as antifriction, wear resistance, and corrosion resistance by combining a coating with a texture, so as to prolong the service life of the oil and gas equipment, increase oil and gas production efficiency.

A method of using a bowl protector assembly includes lowering the bowl protector assembly with a running and retrieving tool into a wellhead located at a surface of a well, whereby a removable upper module of the bowl protector assembly is damaged, wherein the bowl protector assembly comprises the removable upper module and a lower module and the removable upper module comprises tool engagement features to pair with the running and retrieving tool. The method further includes raising the bowl protector assembly out of the wellhead and replacing the damaged removable upper module with an undamaged removable upper module. The method further includes lowering the bowl protector assembly comprising the undamaged removable upper module with the running and retrieving tool into the wellhead and placing the bowl protector assembly on a load shoulder within the wellhead.
