Abstract
Wellbore electrical cables include at least one insulated conductor, at least one layer of armor wires surrounding the insulated conductor, and a polymeric material disposed in the interstitial spaces formed between armor wires and interstitial spaces formed between the armor wire layer and insulated conductor which may further include wear resistance particles or even short fibers, and the polymeric material may further form a polymeric jacket around an outer, layer of armor wires. The insulated conductor is formed from a plurality of metallic conductors encased in an insulated jacket. Further disclosed are methods of using the cables of the invention in seismic and wellbore operations, including logging operations.
