Abstract
A technique for manufacturing slickline with a jacket of enhanced bonding. The technique may include roughening an outer surface of a metal core and applying an initial insulating polymer layer to the roughened core in a non-compression manner such as by tubing extrusion. The insulated core may then be heated and run through a set of shaping rollers. Thus, the grip between the polymer and the underlying metal core may be enhanced at a time following the initial placement of the polymer on the core. In this manner, processing damage to the underlying core surface which might adversely affect maintaining the grip may be minimized. Other techniques such as powder spray delivery of the initial polymer layer may also be utilized in a similar manner.
