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

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.

2 . The tool as claimed in claim 1 further comprising a shiftable sleeve 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.

3 . The tool as claimed in claim 2 wherein the sleeve is shiftable mechanically with a shifting profile.

4 . The tool as claimed in claim 2 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.

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

6 . The tool as claimed in claim 5 wherein the securement is a dog or a snap ring.

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

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

9 . The tool as claimed in claim 1 wherein the nose defines flow openings.

10 . 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 retrieving a tapered nose of the tool.

11 . The method as claimed in claim 10 further comprising shifting a sleeve disposed radially inwardly of the tapered nose to release a securement between the tapered nose and the housing.

12 . The method as claimed in claim 10 further comprising prior to retrieving the tapered nose, flowing fluid through the tapered nose.

13 . The method as claimed in claim 12 wherein the flowing is through a central hole defined by the tapered nose.

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

15 . The method as claimed in claim 10 further comprising prior to retrieving the tapered nose, running a separate tool through the tapered nose.

16 . 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.
