Abstract

Disclosed is an improved tension member or slickline used in wellbore intervention operations. One exemplary tension member includes a first portion comprising a metallic material and having a distal end, a second portion comprising a non-metallic material and having a proximal end, and a joint coupling the proximal end of the second portion to the distal end of the first portion.

First claim

The invention claimed is:

1. A tension member, comprising:
a first portion comprising a metallic material having a distal end comprising at least one groove formed in an outer surface of the distal end; and
a second portion comprising a non-metallic material having a proximal end, wherein an inner surface of the proximal end of the second portion is directly connected to the at least one groove on the outer surface of the distal end of the first portion at a joint comprising a transition point between the first portion and the second portion.

2. The tension member of claim 1 , wherein the metallic material is selected from the group consisting of steel, plow steel, stainless steel, INCONEL®, carbon steel, alloy steel, spring steel, maraging steel, weathering steel, and tool steel.

3. The tension member of claim 1 , wherein the non-metallic material comprises at least one of a plastic, a composite, and an elastomer.

4. The tension member of claim 3 , wherein the composite comprises a polymer reinforced with one or more of carbon fibers, carbon nanotubes, glass fibers, fiberglass, polymer fibers, metal fibers, ceramic fibers, and combinations thereof.

5. The tension member of claim 1 , wherein the joint is formed using at least one of a metal-to-composite binding technique, a temperature cure processing, a UV cure processing, a mechanical bonding technique, a hydraulic pressure bonding technique, and an adhesive, or any combination thereof.

6. The tension member of claim 1 , wherein the joint comprises braiding the proximal end of the second portion onto the distal end of the first portion.

7. The tension member of claim 1 , wherein the distal end of the first portion tapers along at least a portion of the joint.

8. The tension member of claim 7 , wherein the at least one groove comprises a series of grooves defined along at least a portion of the outer surface of the distal end.

9. The tension member of claim 8 , wherein the series of grooves are defined helically or non-helically along the portion of the outer surface of the distal end.

10. The tension member of claim 1 , wherein the distal end of the first portion defines at least two mutually tapering portions that taper along at least a portion of the joint.

11. The tension member of claim 10 , further comprising a series of grooves defined along at least a portion of an outer surface of the distal end.

12. The tension member of claim 1 , wherein the joint is a first joint and the non-metallic material is a first non-metallic material, the tension member further comprising a third portion made of a second non-metallic material and directly connected to the second portion at a second joint.

13. The tension member of claim 12 , wherein the first and second non-metallic materials are least one of a plastic, a composite, and an elastomer.

14. The tension member of claim 13 , wherein the composite comprises a polymer reinforced with one or more of carbon fibers, carbon nanotubes, glass fibers, fiberglass, polymer fibers, metal fibers, ceramic fibers, and combinations thereof.

15. The tension member of claim 13 , wherein one or both of the first and second joints are braided joints.

16. A method for introducing a downhole tool into a wellbore, comprising:
coupling the downhole tool to an end of a slickline, wherein the slickline has at least a first portion made of a metallic material and a second portion made of a first non-metallic material disposed length wisely adjacent to the first portion of the metallic material along a length of the slickline, and wherein a proximal end of the second portion is directly connected to a distal end of the first portion at a first joint, wherein the distal end comprises at least one groove formed in an outer surface of the distal end;
placing the downhole tool in a lubricator coupled to a wellhead of the wellbore, the lubricator having a stuffing box through which the slickline is extended and sealed; and
conveying the downhole tool into the wellbore by feeding the slickline through the stuffing box.

17. The method of claim 16 , further comprising:
feeding the first joint through the stuffing box; and
maintaining a seal on the slickline as the first joint passes through the stuffing box.

18. The method of claim 16 , wherein the first non-metallic material is at least one of a plastic, a composite, and an elastomer.

19. The method of claim 18 , wherein the composite is selected from the group consisting a polymer reinforced with one or more of carbon fibers, carbon nanotubes, glass fibers, polymer fibers, metal fibers, ceramic fibers, and combinations thereof.

20. The method of claim 16 , wherein the slickline further comprises a third portion made of a second non-metallic material and directly connected to the second portion at a second joint, the method further comprising:
feeding the first and second joints through the stuffing box, the first and second joints exhibiting respective outside diameters substantially similar to that of the first, second, and third portions; and
maintaining a seal on the slickline as the first and second joints pass through the stuffing box.

21. The method of claim 20 , wherein the first and second non-metallic materials are least one of a plastic, a composite, and an elastomer.

22. The method of claim 21 , wherein the composite is selected from the group consisting a polymer reinforced with one or more of carbon fibers, carbon nanotubes, glass fibers, polymer fibers, metal fibers, ceramic fibers, and combinations thereof.
