Abstract: Sensors for imaging boreholes via the detection of electrical and optical properties may be subject to harsh conditions downhole, such as from pressure and temperature. In addition, these sensors may be subject to impact, such as tension, elongation, and compression forces, along the wall of the borehole. The harsh conditions downhole and impacts on the sensor can lead to premature wear and even breaking. The present disclosure generally relates to an apparatus for measuring electrical and optical properties of the borehole and methods for manufacturing the apparatus.

Abstract: A cable that has a cable core with a first armor wire layer and a second armor wire layer. The second armor wire layer is segregated from the first armor wire layer, and an outer jacket is disposed about the second armor wire layer.

Abstract: A cable containing a conductive outer layer and methods for manufacturing the conductive outer layer and the cable are provided. A cable may include a cable core and a plurality of armor wire strength members that surround the cable core. The cable may also include a conductive outer layer disposed about the plurality of armor wire strength members that physically contacts at least one armor wire strength member of the plurality of armor wire strength members.

Abstract: A method and method of using a cable that includes a cable core. The cable core has an inner armor wire layer disposed thereabout. The inner armor wire layer has an outer armor wire layer disposed thereabout. The inner armor wire layer and outer armor wire layer have torque removed therefrom during manufacturing.

Abstract: Packoff seals and processes for using same. In some examples, the packoff seal can include a first end cap and a second end cap, a first insert and a second insert, a first deformable element disposed between the first end cap and the first insert, a second deformable element disposed between the second insert and the second end cap, and a third deformable element disposed between the first insert and the second insert. The first end cap, the first deformable element, the first insert, the third deformable element, the second insert, the second deformable element, and the second end cap together can form a body having a bore extending therethrough. The first deformable element, the second deformable element, and the third deformable element can have a compressive strength that is less than a compressive strength of the first and second inserts.

Abstract: Electrical conductors and processes for making and using same. In some examples, the electrical conductors can include an inner electrically conductive element, which can define a central longitudinal axis. A first polymer layer can be disposed circumferentially about the inner electrically conductive element. A plurality of electrical conductor segments can be disposed about the first polymer layer and spaced around the central longitudinal axis. A second polymer layer can be disposed between the electrical conductor segments. The second polymer layer and the electrical conductor segments together can define a substantially annular cross-sectional area and an outer perimeter surface. An electrical insulator can be disposed about the outer perimeter surface defined by the second polymer layer and the electrical conductor segments.

Abstract: A downhole cable that has a cable core with an inner jacket located about it. The inner jacket has a shell located thereabout, and a pair of strength member layers surrounds the inner shell. Interstitial spaces of the strength member layers are filled with bonding layers.
