Abstract

An assembly and process for identifying and tracking assets, particularly tubulars, equipment, tools and/or devices. An antenna is electrically connected to a responding device, such as a radio frequency identification device, and this assembly is connected to an asset. The antenna may be positioned about the exterior and/or the interior of the asset and significantly increases the range of signals that may be received and/or broadcast by the responding device. A transceiver may accordingly be positioned a greater distance from the asset without regard to the orientation of the asset and still permit communication between the transceiver and the responding device. In this manner, information that specifically identifies the asset may be compiled in a data base so as to maintain an accurate history of the usage of such assets as tubulars, equipment, tool and/or devices.

Claims

1. An assembly for identifying and tracking an asset comprising:

a responding device adapted to be connected to an asset;

a first antenna electrically connected to said responding device and extending along the outer periphery of said asset; and

a second antenna electrically connected to said responding device and extending along the inner periphery of said asset.

2. The assembly of claim 1 wherein said responding device is a radio frequency identification device.

3. The assembly of claim 2 wherein said radio frequency identification device is passive.

4. The assembly of claim 1 wherein said antenna extends substantially around the entire outer periphery of said asset.

5. The assembly of claim 1 wherein said asset has a groove in the outer surface thereof and said responding device and said first antenna are positioned within said groove.

6. The assembly of claim 5 wherein said responding device is a radio frequency identification device.

7. The assembly of claim 6 wherein said radio frequency identification device is passive.

8. The assembly of claim 5 wherein said groove extends substantially around the entire outer periphery of said asset.

9. The assembly of claim 8 wherein said groove is generally annular.

10. The assembly of claim 8 wherein said first antenna extends substantially around the entire outer periphery of said asset.

11. The assembly of claim 5 further comprising:

a sealant positioned in said groove so as to surround and secure said responding device and said first antenna in said groove.

12. The assembly of claim 1 wherein said responding device is positioned within a hole in said asset.

13. The assembly of claim 1 wherein at least a portion of the interior of said asset has screw threads.

14. The assembly of claim 1 wherein said second antenna is embedded in a ring having a threaded outer surface that is mated with said screw threads of said interior of said asset.

15. An assembly for use as a fluid conduit comprising:

a tubular;

a responding device connected to said tubular;

a first antenna electrically connected to said responding device and extending along the outer periphery of said tubular; and

a second antenna electrically connected to said responding device and extending along the inner periphery of said tubular.

16. The assembly of claim 15 wherein said responding device is a radio frequency identification device.

17. The assembly of claim 16 wherein said radio frequency identification device is passive.

18. The assembly of claim 15 wherein said tubular has a groove in the outer surface thereof and said responding device and said first antenna are positioned within said groove.

19. The assembly of claim 18 wherein said responding device is a radio frequency identification device.

20. The assembly of claim 19 wherein said radio frequency identification device is passive.

21. The assembly of claim 18 wherein said groove extends substantially around the entire outer periphery of said tubular.

22. The assembly of claim 21 wherein said groove is generally annular.

23. The assembly of claim 21 wherein said first antenna extends substantially around the entire outer periphery of said tubular.

24. The assembly of claim 18 further comprising:

a sealant positioned in said groove so as to surround and secure said responding device and said first antenna in said groove.

25. The assembly of claim 15 wherein said responding device is positioned within a hole in said tubular.

26. The assembly of claim 15 wherein at least a portion of the interior of said generally tubular body has screw threads.

27. The assembly of claim 15 wherein said second antenna is embedded in a ring having a threaded outer surface that is mated with said screw threads of said interior of said tubular.

28. The assembly of claim 15 wherein said tubular is drill pipe and the fluid conduit is a drill string for use in a subterranean well.

29. The assembly of claim 15 wherein said tubular is tubing and the fluid conduit is a tubing string for use in a subterranean well.

30. The assembly of claim 15 wherein said tubular is pipe and the fluid conduit is a pipeline.

31. The assembly of claim 15 further comprising:

a tool connected to said tubular; and

a second responding device connected to said tool.

32. An assembly for use as a fluid conduit comprising:

a tubular;

a collar releasably secured to one end of said tubular, said collar comprising a generally tubular body;

a responding device connected to said generally tubular body;

a first antenna electrically connected to said responding device and extending along the outer periphery of said generally tubular body; and

a second antenna electrically connected to said responding device and extending along the inner periphery of said generally tubular body.

33. The assembly of claim 32 wherein said responding device is a radio frequency identification device.

34. The assembly of claim 33 wherein said radio frequency identification device is passive.

35. The assembly of claim 32 wherein said first antenna extends substantially around the entire outer periphery of said generally tubular body.

36. The assembly of claim 32 wherein said generally tubular body has a groove in the outer surface thereof and said responding device and said first antenna are positioned within said groove.

37. The assembly of claim 36 wherein said responding device is a radio frequency identification device.

38. The assembly of claim 37 wherein said radio frequency identification device is passive.

39. The assembly of claim 36 wherein said groove extends substantially around the entire outer periphery of said generally tubular body.

40. The assembly of claim 39 wherein said groove is generally annular.

41. The assembly of claim 39 wherein said first antenna extends substantially around the entire outer periphery of said generally tubular body.

42. The assembly of claim 36 further comprising:

a sealant positioned in said groove so as to surround and secure said responding device and said first antenna in said groove.

43. The assembly of claim 32 wherein said responding device is positioned within a hole in said generally tubular body.
