In accordance with some embodiments of the present disclosure, a shape memory alloy rope socket for a downhole tool is disclosed. The rope socket includes a coupler formed of a shape memory alloy. The rope socket further includes a housing surrounding the coupler. The housing including a pathway and a connector for attaching a downhole tool is attached. The rope socket further includes a line passing through the pathway and the coupler such that the coupler is in contact with the line along a length of the coupler when the coupler is in a reduced diameter state.

A drill-pipe communication assembly includes a first drill pipe segment. A conductor extends at least partially along a length of the first drill pipe segment. An antenna is electrically coupled to the first drill pipe segment. The antenna facilitates wireless transmission of signals from the first drill pipe segment to an adjacent second drill pipe segment.

Coating compositions for coating fluid handling components, and related methods, may include in some aspects a coating composition having a trifunctional silane, a silanol, and a filler. The coating composition may be applied to a surface of a fluid handling component that is configured to be exposed to a fluid. The coating composition may be applied to at least partially cover or coat the surface. The coating composition may be configured to chemically bond with a cured primer composition that includes an epoxy.

Methods for providing wellbores for electromagnetic heating of a hydrocarbon formation positioned below a ground surface and apparatus thereof are provided. The apparatus includes two or more wellbore casings positioned within two or more wellbores. The two or more wellbores extend from a proximal end at the ground surface to a distal end at the underground hydrocarbon formation. Each of the two or more wellbore casings have a proximal portion and a distal portion. The two or more wellbores are in proximity to one another at a junction. The apparatus also includes a first electrical connection between the proximal portions of the two or more wellbore casings for grounding the two or more wellbore casings and a second electrical connection between the distal portions of the two or more wellbore casings. The second electrical connection is located at the junction and provides a short circuit that reduces current traveling on the two or more wellbore casings to the ground surface.

A downhole component including a first portion; a second portion; a controlled failure structure between the first portion and second portion. A method for improving efficiency in downhole components.

A tubular string formed by one or more tubulars with a central flow passage for an internal fluid therethrough and an external surface. The tubular having a wall thickness defined between external surface and the central flow passage and at least one sensor port disposed along a longitudinal length of the tubular. At least one sensor includes a main body and=nipple extending from the main body and inserted into the sensor port of the tubular. The nipple extends through the wall thickness sufficient to detect a property of an internal fluid within the central flow passage.

A wellbore assembly can include a completion string having a side pocket. A downhole device can be positioned within the side pocket of the completion string. The downhole device can have a first end sized and shaped for coupling to a tool for inserting and removing the downhole device in the side pocket while the completion string is positioned downhole in a wellbore. The downhole device can be an electronic device.

A modular anti-rotation device for preventing rotation with respect to the central axis of a drilling tool in a borehole and for producing a notch in a borehole surface. The anti-rotation device includes an upper fixture portion and a lower fixture portion in axial alignment. The upper fixture portion and the lower fixture portion are connected by yoke assemblies. Each yoke assembly is connected to the fixture portion and fixture portion at one end, and forming an articulated joint of the upper yoke assembly and the lower yoke assembly at a distal end opposite the first end. A roller is connected at each joint, connecting the upper and lower yoke assemblies. The rollers engage vertically with a borehole surface, the rollers travelling axially, as a drill shaft penetrates into the borehole, the rollers simultaneously preventing radial movement of the anti-rotation device and prevent rotation with respect to the central axis of the borehole.
