Abstract (en)

[origin: WO9948111A1] A cable (10) for use in the deployment of services in a wellbore as described which comprises a conductive core (12) which is insulated from at least one layer (18, 20) of armour wires by an insulating layer (16). To control the migration of well fluids through the pressure control equipment, the voids (24) between the armour wires (22) are filled with a resilient material to prevent well fluids from seeping into the voids (24) between the armour wires causing damage to the cable (10). The resilient material binds strongly to the armour wires (22) preventing the armour wires from separating, even after repeated use or loss of tension. Thus, the armour filled with resilient material provides satisfactory mechanical strength for bearing relatively large loads. The resilient material also provides the cable with a smooth outside surface.
