A cable system for use downhole includes a connector assembly having a body and a bore formed therethrough; a conductor disposed through the bore of the connector assembly; and a first insulation layer disposed around the conductor. An insulator tube is disposed around the conductor and has an end attached to the first insulation layer. The insulator tube may be made of a thermoplastic material. A graphite containing sealing member is disposed in the bore and disposed between the insulator tube and the body of the connector assembly.

A downhole well tool includes a tool body attached to a well string, a sealing packer element partially circumscribing the tool body from a first circumferential end to a second circumferential end, a side groove formed at least partially in the tool body and positioned between the first circumferential end and the second circumferential end of the sealing packer element, and a fluid conduit disposed within the tool body and extending to the side groove. The sealing packer element expands and seals against an inner wall of a wellbore. The side groove forms a channel in an exterior surface of the tool body between the first circumferential end and the second circumferential end of the sealing packer element, and the fluid conduit includes at least one nozzle positioned at the side groove, where the fluid conduit flows a fluid into the channel of the side groove.

A fluid end is coupled to and configured to be driven by an electric motor. A shear interconnect is at an uphole end of the electric submersible pump. The shear interconnect is configured to shear a cable line between the electric submersible pump and a topside facility. The shear interconnect is configured to shear the cable at the electric submersible pump. A safety valve is arranged to cease flow within a wellbore, in which the electric submersible pump is installed, when the safety valve is in a closed position.

An over element line protector comprises a body having a first major surface including a first curvature of a first radius and a second major surface including a second curvature having a second smaller radius. The second radius is smaller than the first radius. The body has a longitudinal extent and a central region aligned with and along the longitudinal extent. The central region is of a first thickness. Wing regions extend laterally from the central region and have a second smaller thickness than the first thickness. A passageway is located in the central region extending along the longitudinal extent of the body configured to protect a line therein.

A method performed during a run-in-hole process for a casing section includes applying pressure to a cable against an outer portion of the casing section. Additionally, the method includes ultrasonic welding the cable to the outer portion of the casing section while the pressure is applied to the cable against the outer portion of the casing section.

Provided is a downhole rotary slip ring joint, a well system, and a method for accessing a wellbore. The downhole rotary slip ring joint, in one aspect, includes an outer mandrel, an inner mandrel operable to rotate relative to the outer mandrel, an outer mandrel communication connection coupled to the outer mandrel, and an inner mandrel communication connection coupled to the inner mandrel. The downhole rotary slip ring joint, according to this aspect, further includes a passageway extending through the outer mandrel and the inner mandrel, the passageway configured to provide continuous coupling between the outer mandrel communication connection and the inner mandrel communication connection regardless of a rotation of the inner mandrel relative to the outer mandrel, wherein the downhole rotary slip ring joint is operable to be coupled to a wellbore access tool.
