Abstract: 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.

Abstract: 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.
