Various cables for cable deployed electric submersible pumping systems and methods of manufacturing such cables are provided. The cable includes a power cable core and coiled tubing formed around the power cable core. The power cable core includes one or more conductors, insulation surrounding each conductor, and an elastomeric jacket extruded around the insulated conductors. Various mechanisms, systems, and methods are described to anchor the power cable core in the coiled tubing and to transfer weight from the power cable core to the coiled tubing.

Electrical cables and processes for making and using same. In some examples, the electrical cable can include one or more insulated electrical conductors and one or more metallic elements cabled together and a metallic layer disposed about the one or more insulated electrical conductors and the one or more metallic elements. The one or more metallic elements can partially fill a space located between the one or more insulated electrical conductors and the metallic layer. The one or more insulated electrical conductors can each include an electrically conductive core, a layer of electrically insulating material disposed about the electrically conductive core, and a layer of metallic strands disposed about the layer of electrically insulating material.

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.

Electrical conductors and processes for making and using same

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. One of the strength member layers is at a contra-helical lay angle to the other. An outer jacket is located about one of the strength member layers, and the outer jacket is bonded with the bonding layers.

Downhole cables and methods of making the same

A dual use cable includes at least one fiber optic cable encased in a metallic component that is encased in a layer of polymer material. The polymer material is surrounded by a tube or armor wire strength members embedded in one or two additional polymer material layers. A final assembly can include an outer metallic component or an outer layer of polymer material. The at least one fiber optic cable transmits data and the armor wire strength members and/or metallic components transmit at least one of electrical power and data.

A cable that include a hose having a conductor located thereabout. A first strength member layer is located about the conductor. A second strength member layer is located about the first strength member layer. A first jacket is located about the second strength member layer. The first jacket is fiber-reinforced. A second jacket is located about the first jacket. The second jacket is a contrasting color to the first jacket.

Cables and methods of making cables

A technique facilitates the employment of an electric submersible pumping system or other well system downhole into a wellbore. The electric motor system is coupled with a signal carrying cable for conveyance to a desired downhole location in the wellbore. The signal carrying cable is constructed with sufficient strength to solely support the electric motor system during deployment and use in the wellbore without addition of a separate supporting mechanism.

Permanent cable for submersible pumps in oil well applications

A hydrocarbon application hose to avoid substantial compression and blow-out resulting from high pressurization differentials therethrough. The hose is formed from an inner tube that has a layer of material with electromagnetic target, such as carbon fiber, disbursed therethrough. In this manner, the material, generally a polymer, may be electromagnetically heated once the layer has been wrapped with a metallic reinforcing member. Thus, the layer of material may transform into surrounding relation relative to the reinforcing member. A substantially unitary inner tube may thereby be provided that includes a reinforcing member for blowout resistance and is of unitary character for compression resistance.

An electrical cable having a polymeric inner layer enclosing a cable core, and a polymeric outer layer enclosing the cable core and the inner layer. The outer layer operable to maintain integrity of the cable within a predetermined temperature range.

Enhanced electrical seismic land cable

A heating and distributed-temperature-sensor cable permanently fixed in a wellbore that permits known amounts of heat to be introduced to subsurface formations and improved temperature measurement thereof. The heat is introduced into a target zone of the wellbore by forming the cable in two sections: an upper section that carries an electrical current without generating significant amounts of heat, and a lower section that generates heat from the electrical current. Continuous distributed-temperature-sensing is performed through measuring various scattering mechanism in optical fibers that run the length of the cable.
