Abstract

A method of using a down-hole cable apparatus includes placing the down-hole cable apparatus in an operational position. The down-hole cable apparatus includes a metal tube, at least one conductor positioned within the metal tube, an armor shell positioned exterior of the metal tube and the at least one conductor, and a polymer material abutting the metal tube. The polymer material has at least one additive andremains substantially inert during a recrystallization process. The down-hole cable apparatus is subjected to an operational catalyst, during which time the polymer material having the at least one additive remains substantially inert. The inertia prevents linear separation of at least one of the at least one conductor and the armor shell from the metal.

Claims

1. A method of using a down-hole cable apparatus, the method comprising the steps of:

placing the down-hole cable apparatus in an operational position, wherein the down-hole cable apparatus comprises a metal tube, at least one conductor positioned within the metal tube, an armor shell positioned exterior of the metal tube and the at least one conductor, and a polymer material abutting the metal tube, wherein the polymer material includes therein at least one additive, wherein the polymer material with the at least one additive remains substantially inert during a recrystallization process; and

subjecting the down-hole cable apparatus to an operational catalyst, wherein while the down-hole cable apparatus is subjected to the operational catalyst, the polymer material having the at least one additive remains substantially inert, thereby preventing linear separation of at least one of the at least one conductor and the armor shell from the metal.

2. The method of claim 1, wherein the operational catalyst further comprises at least one of:

a temperature increase; and

a pressure increase.

3. The method of claim 1, further comprising the step of removing the operational catalyst from the down-hold cable apparatus, wherein substantially immediately after the operational catalyst is removed from the down-hole cable apparatus, the polymer material having the at least one additive remains substantially inert, thereby preventing linear separation of at least one of the at least one conductor and the armor shell from the metal.

4. The method of claim 1, wherein the at least one additive further comprises at least one of talc, glass beads, nano clay, barium sulphate, calcium carbonate, and silicate.

5. The method of claim 1, wherein the at least one additive within the polymer material further comprises 4% to 80% of the polymer material.
