Abstract

A method of making a downhole servicing tool comprising explosively welding a corrosion resistant material to a corrodible surface of the downhole servicing tool to yield a coated surface, wherein the coated surface comprises an explosively-welded corrosion resistant material.

First claim

What is claimed is:

1. A method of making a downhole servicing tool comprising:
explosively welding a corrosion resistant material to a corrodible surface of the downhole servicing tool to yield a coated surface, wherein the coated surface comprises an explosively-welded corrosion resistant material;
mounting a gauge carrier into the downhole servicing tool, wherein the gauge carrier comprises one or more gauge carrier slots and one or more blank adaptors further comprising one or more gauges to log data about a natural resource reservoir, wherein the gauge carrier slot comprises at least a portion of a coated surface, and wherein the one or more gauges sense a condition proximate the downhole servicing tool; and
forming a sealing interface by sealingly contacting the one or more blank adaptors with the one or more gauge carrier slots.

2. The method of claim 1 wherein the corrodible surface comprises low alloy steel, carbon steel, mild steel, low-carbon steel, low-alloy carbon steel, plain-carbon steel, medium carbon steel, high-carbon steel, ultra-high-carbon steel, or combinations thereof.

3. The method of claim 1 wherein the corrosion resistant material comprises a corrosion resistant alloy, high alloy steel, stainless steel, nickel alloy, Inconel, a corrosion resistant metal, titanium, zirconium, or combinations thereof.

4. The method of claim 1 wherein the explosively-welded corrosion resistant material is characterized by a thickness of from about 0.1 mm to about 10 mm.

5. The method of claim 1 wherein the corrosion resistant material and the corrodible surface comprise dissimilar materials.

6. The method of claim 1 wherein the corrodible surface has a tubular and/or cylindrical geometry.

7. The method of claim 1 wherein the corrodible surface comprises a corrodible surface in a port, a corrodible surface in a slot, a corrodible surface on a tubular, a corrodible surface on a mandrel, a corrodible surface in a housing, or combinations thereof.

8. The method of claim 1 wherein two or more components of the downhole servicing tool are in sealing contact with each other, thereby forming a sealing interface.

9. The method of claim 8 wherein the sealing interface comprises at least a portion of a first surface of a first component in sealing contact with at least a portion of a second surface of a second component, wherein all or a portion of the first surface and/or all or a portion of the second surface may comprise the coated surface.

10. The method of claim 9 wherein the first component comprises a gauge carrier slot and the second component comprises a blank adaptor.

11. The method of claim 9 wherein the first component comprises a mandrel and/or a housing and the second component comprises an annular piston.

12. The method of claim 9 wherein the first component comprises a hydraulic holddown piston and the second component comprises a piston slot.

13. The method of claim 1 wherein explosively welding the corrosion resistant material to the corrodible surface of the downhole servicing tool involves detonating an explosive placed proximate the corrosion resistant material.

14. The method of claim 13 wherein the explosive comprises cyclotrimethylene trinitramine (RDX) characterized by molecular formula C 3 H 6 N 6 O 6 ; pentaerythritol tetranitrate (PETN) characterized by molecular formula C 5 H 8 N 4 O 12 ; trinitrotoluene (TNT) characterized by molecular formula C 7 H 5 N 3 O 6 ; trinitrophenylmethylinitramine characterized by molecular formula C 7 H 5 N 5 O 8 , also known as tetryl; nitroguanidine characterized by molecular formula CH 4 N 4 O 2 ; lead azide characterized by molecular formula Pb(N 3 ) 2 ; ammonium nitrate characterized by molecular formula NH 4 NO 3 ; ammonium nitrate sensitized with fuel oil; ammonium perchlorate characterized by molecular formula NH 4 ClO 4 ; amatol; sodatol; Composition B; Composition C4; dynamite; detasheet; or combinations thereof.

15. The method of claim 1 wherein the downhole servicing tool comprises at least one of a drill stem testing tool, a sampling tool, a completion tool, and a perforating tool or at least one of a logging tool and a drilling tool.

16. The method of claim 15 wherein the drill stem testing tool comprises a valve assembly, a packer, a perforated pipe, and a shoe.

17. The method of claim 16 wherein the drill stem testing tool further comprises a bypass valve, a safety joint, a sample container, a perforating gun, or combinations thereof.

18. The method of claim 15 wherein there is a piston assembly comprising a housing, a mandrel and an annular piston, wherein the housing comprises a first coated surface, wherein the mandrel comprises a second coated surface, wherein the first coated surface and the second coated surface define an annular space, and wherein the annular piston moves within the annular space.

19. The method of claim 18 wherein the piston assembly is a differential pressure piston assembly, and wherein at least a portion of the annular space comprises a fluid.

20. The method of claim 15 wherein there is a port selectively openable and/or closeable to fluid flow.

21. The method of claim 20 wherein the port is configured for a perforating and/or fracturing operation.

22. The method of claim 15 wherein there is a packer comprising a hydraulic holddown mechanism further comprising a hydraulic holddown piston and a piston slot, wherein the hydraulic holddown piston moves within the piston slot.

23. The method of claim 1 , wherein the blank adaptor is in a parameter monitoring configuration.

24. A downhole servicing tool comprising a gauge carrier comprising one or more gauge carrier slots and one or more blank adaptors further comprising one or more gauges, wherein the gauge carrier slot comprises a coated surface, wherein the coated surface comprises an explosively-welded corrosion resistant material, wherein the gauge carrier slot comprises at least a portion of the coated surface in sealing contact with at least a portion of an outer surface of the blank adaptor, thereby forming a sealing interface, wherein the gauge senses a condition proximate the downhole servicing tool.

25. The downhole servicing tool of claim 24 wherein the explosively-welded corrosion resistant material comprises a corrosion resistant alloy, high alloy steel, stainless steel, nickel alloy, Inconel, a corrosion resistant metal, titanium, zirconium, or combinations thereof.

26. The downhole servicing tool of claim 24 comprising at least one of a drill stem testing tool, a sampling tool, a completion tool, and a perforating tool or at least one of a logging tool and a drilling tool.

27. The downhole servicing tool of claim 26 wherein the drill stem testing tool comprises a valve assembly, a packer, a perforated pipe, and a shoe.

28. The downhole servicing tool of claim 26 wherein there is a piston assembly comprising a housing, a mandrel and an annular piston, wherein the housing comprises a first coated surface, wherein the mandrel comprises a second coated surface, wherein the first coated surface and the second coated surface define an annular space, wherein the annular piston moves within the annular space, wherein the annular piston comprises a first outer surface and a second outer surface, wherein at least a portion of the first outer surface of the annular piston forms a first sealing interfac
