Abstract

A tapered nose tool having a closed position and an open position, a degradable nose component, a releasable nose component, that is configured to rotate due to fluid passing therethrough and configured for retrievability of a portion of the bull nose tool.

First claim

The invention claimed is:

1. A pass-through tapered nose tool for a wellbore comprising:
a housing;
a plurality of doors articulated to the housing, the doors having a closed position where they collectively form a tapered geometry and an open position where they allow through passage of other well tools; and
a plurality of opening members extending radially outwardly from an outside surface of each of the plurality of doors.

2. The tool as claimed in claim 1 wherein the doors are shaped such that when in the closed position, a flow port is left open.

3. The tool as claimed in claim 1 wherein the doors are shaped such that when in the closed position, a complete closed nose is formed.

4. The tool as claimed in claim 1 wherein the doors include magnets oriented to attract the doors to a closed position.

5. The tool as claimed in claim 1 further comprising a biasing configuration to urge the doors to a closed position.

6. The tool as claimed in claim 5 wherein the biasing configuration is a torsion spring.

7. The tool as claimed in claim 5 wherein the biasing configuration is a leaf spring.

8. The tool as claimed in claim 5 wherein the biasing configuration is a tension spring.

9. The tool as claimed in claim 5 wherein the biasing configuration is a cone spring.

10. The tool as claimed in claim 1 further comprising a hold member disposed at an intersection between adjacent doors.

11. The tool as claimed in claim 10 wherein the hold member is magnetic.

12. The tool as claimed in claim 10 wherein the hold member is a permanent magnet.

13. A method for operating in a wellbore comprising:
running the tool as claimed in claim 1 into a wellbore;
negotiating downhole profiles with the tool; and
opening the doors of the tool.

14. The method as claimed in claim 13 further including running another tool through the open doors.

15. The method as claimed in claim 13 further including catching the plurality of opening members on a restriction in the wellbore and thereby opening the plurality of doors.

16. The method as claimed in claim 15 further including automatically closing the plurality of doors upon moving beyond the restriction in the wellbore.

17. A wellbore system comprising:
a borehole in a subsurface formation;
a first tubular structure in the borehole; and
a tool as claimed in claim 1 disposed within or as a part of the first tubular structure.

18. A method for operating a wellbore comprising:
running a tool into a wellbore, the tool having a housing, a plurality of doors articulated to the housing, the doors having a closed position where they collectively form a tapered geometry and an open position where they allow through passage of other well tools;
negotiating downhole profiles with the tool;
flowing fluid through a flow port defined by the doors; and
opening the doors of the tool.
