Abstract

A tapered nose tool includes a housing, a retrievable tapered nose disposed in the housing and retrievable from the housing, and a mechanically shiftable sleeve. The mechanically shiftable sleeve is shiftable with a shifting profile disposed in the housing. The sleeve anchors the nose in the housing in a first position and releases the nose from the housing in a second position.

First claim

The invention claimed is:

1. A pass-through tapered nose tool for a wellbore comprising:
a housing;
a retrievable tapered nose disposed in the housing and retrievable from the housing; and
a mechanically shiftable sleeve shiftable with a shifting profile disposed in the housing, the sleeve anchoring the nose in the housing in a first position and releasing the nose from the housing in a second position.

2. The tool as claimed in claim 1 wherein the sleeve includes a torque key to prevent relative rotation between the sleeve and the nose to facilitate contingency drill out of the nose.

3. The tool as claimed in claim 1 further including a securement engagable with the housing through a securement opening of the nose.

4. The tool as claimed in claim 3 wherein the securement is a dog or a snap ring.

5. The tool as claimed in claim 3 wherein the securement is maintained in engagement with the housing by a shifting sleeve radially inwardly disposed of the nose.

6. The tool as claimed in claim 1 wherein the nose defines a central hole.

7. A pass-through nose tool for a wellbore comprising:
a housing;
a retrievable tapered nose disposed in the housing and retrievable from the housing, wherein the nose defines flow openings.

8. A method for operating in a wellbore comprising:
running the tool as claimed in claim 1 into the wellbore;
negotiating downhole profiles with the tool; and
retrieving a tapered nose of the tool.

9. The method as claimed in claim 8 further comprising shifting the sleeve to release a securement between the tapered nose and the housing.

10. A method for operating in a wellbore comprising:
running a tool into the wellbore, the tool having:
a housing; and
a retrievable tapered nose disposed in the housing and retrievable from the housing;

negotiating downhole profiles with the tool; and
retrieving a tapered nose of the tool, further comprising prior to retrieving the tapered nose, flowing fluid through the tapered nose.

11. The method as claimed in claim 10 wherein the flowing is through a central hole defined by the tapered nose.

12. The method as claimed in claim 10 wherein the flowing is through a hole defined within a frustoconical surface of the tapered nose.

13. A method for operating in a wellbore comprising:
running a tool into the wellbore, the tool having:
a housing; and
a retrievable tapered nose disposed in the housing and retrievable from the housing;

negotiating downhole profiles with the tool; and
retrieving a tapered nose of the tool, further comprising prior to retrieving the tapered nose, running a separate tool through the tapered nose.

14. 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.
