Abstract
Official abstract text for this publication.
An embodiment of a wellbore cable comprises a cable core, at least a first armor wire layer comprising a plurality of strength members and surrounding the cable core, and at least a second armor wire layer comprising a plurality of strength members surrounding the first armor wire layer, the second armor wire layer covering a predetermined percentage of the circumference of the first armor wire layer to prevent torque imbalance in the cable.
First claim
Opening claim text (preview).
What is claimed is: 1. A wellbore cable, comprising: three conductors, each comprising a cable core encased in a polymeric jacket, an inner armor wire layer disposed against the cable core at a lay angle, and a polymeric layer encasing the inner armor wire layer, wherein an additional armor wire layer covers a predetermined percentage of the circumference of the inner armor wire layer, wherein the predetermined percentage and radial spacing are selected to prevent torque imbalance…
