Apparatus and methods for coupling a rope socket with an armored cable. The armored cable includes a conductor core having one or more cables for transmitting electrical and/or optical signals and at least one layer of armor wires wound around the conductor core. The rope socket includes a housing having an uphole end through which the armored cable extends into the housing and a downhole end through which the conductor core extends from the housing to a component of downhole equipment suspended in a wellbore by the armored cable. The armor wires are arranged inside of the housing so that they are spaced apart at least locally from the conductor core. A plastic material disposed within the housing fills interstices each defined by one or more surfaces of one or more of the conductor core, one or more of the armor wires, and the housing.

Composite cable rope socket

The disclosure relates to a cable () comprising a core () and a plurality of reinforcing elements () arranged around the core () so as to cover the core (), wherein each reinforcing element () includes at least a bundle of reinforcement fibers comprising at least one fiber and a thermoset matrix impregnating the bundle of fibers, wherein each reinforcing element () is individually tubed with a thermoplastic coating ().

Cable, in particular for downhole use, and method of manufacturing such cable

A centralizer operable to connect with and centralize a downhole tool within a tubular string within a wellbore and to facilitate reception of electromagnetic signals transmitted through the Earth. The centralizer has a body, a first contacting member electrically connected to the body and extending radially away from the body such that the first contacting member contacts an inner surface of the tubular string to electrically connect the tubular string to the body, and a second contacting member electrically insulated from the body and extending radially away from the body such that the second contacting member contacts the inner surface of the tubular string to centralize at least a portion of the body within the tubular string.
