Cables that include a conductor and an optical fiber. In some embodiments, the cable can include an optical fiber loosely disposed within an enclosure. A conductor layer can be disposed about the enclosure. An insulation layer can be disposed about the at least one conductor layer. An inner layer of armor strength members can be helically disposed about the insulation layer. An outer layer of armor strength members can be helically disposed about the inner layer of armor strength members. The armor strength members in the outer layer of armor strength members can be at an opposite helix compared to the armor strength members in the inner layer of armor strength members. An outer jacket can be disposed about the outer layer. In other embodiments, the cable can include an optical fiber in a coupled electro-optical package, where the conductor layer can be disposed about the electro-optical package.

Electro-optical wireline cables

A fiber optic thread assembly configured with a cumulative gap for mechanical responsiveness and protection from micro-bend damage. The assembly may be incorporated into a wireline or slickline cable for obtaining fiber optic readings of enhanced accuracy during an application in a well. The gap is uniquely tailored to allow for a natural reduction during deployment of the cable into the well, thereby providing the enhanced accuracy. However, the gap is also sufficient to help avoid micro-bend damage from the resulting mechanical responsiveness, which is attained upon deployment of the cable into the well.

Mechanically responsive fiber optic thread assembly

A wireline cable includes an electrically conductive cable core for transmitting electrical power. The wireline cable further includes an inner layer of a plurality of first armor wires surrounding the cable core and an outer layer of a plurality of second armor wires surrounding the inner layer, wherein a diameter of the outer layer of the plurality of second armor wires is smaller than a diameter of the inner layer of the plurality of first armor wires.

Reduced torque wireline cable

The present disclosure relates to a cable that includes a core, a first armor wire layer surrounding the core, a first polymer layer disposed around the first armor wire layer, where the first polymer layer has a first sensitivity to energy emitted from an energy source, a second armor wire layer that may be disposed at least partially in the first polymer layer, and a second polymer layer disposed around the second armor wire layer, where the second polymer layer has a second sensitivity to the energy emitted from energy source, and the second sensitivity is greater than the first sensitivity.
