Abstract:
1. A method for use of a wireline cable, comprising: providing a torque balanced wireline cable, the cable including a cable core and a substantially smooth exterior surface; wherein providing comprises providing an electrically conductive cable core for transmitting electrical power; disposing an inner armor wire layer around the cable core; and disposing an outer armor wire layer around the inner armor wire layer, wherein a torque on the cable is balanced by forming the outer armor layer with a predetermined amount of coverage of less than an entire circumference of the inner armor wire layer; attaching a tractor to the cable; and introducing the tractor and the cable into a wellbore, wherein a torque on the cable is balanced and friction between the cable and the wellbore is minimized by the exterior surface as the tractor pulls the cable through the wellbore.
