Abstract
Disclosed are high strength wellbore electric cables, which are formed from a plurality of strength members. The strength members are formed from several stranded filament wires which may be encased within a jacket of polymeric material. The strength members may be used as a central strength member, or even layered around a central axially positioned component or strength member, to form a layer of strength members. Cables of the invention may be of any practical design, including monocables, coaxial cables, quadcables, heptacables, slickline cables, multi-line cables, etc., and have improved resistant to corrosion, torque balancing, and gas migration from a wellbore to the surface.
