Pass-through tapered nose tool

Abstract

A pass-through tapered nose tool for a wellbore including a housing mounting portion, and a tapered nose component including a degradable material attached to the housing mounting portion. A method for operating in a wellbore including running the tool into a wellbore, negotiating downhole profiles with the tool, and degrading the degradable portion of the tapered nose component of the tool.

1 . A pass-through tapered nose tool for a wellbore comprising:
 a housing mounting portion; and   a tapered nose component including a degradable material attached to the housing mounting portion.   
     
     
         2 . The tool as claimed in  claim 1  wherein the tapered nose component is entirely formed of the degradable material. 
     
     
         3 . The tool as claimed in  claim 1  wherein the tapered nose component defines an opening therein. 
     
     
         4 . The tool as claimed in  claim 3  wherein the opening extends along a longitudinal axis of the component. 
     
     
         5 . The tool as claimed in  claim 1  wherein the tapered nose component defines a plurality of openings therein, at least one of which is defined as an angle to a longitudinal axis of the component. 
     
     
         6 . The tool as claimed in  claim 5  wherein each opening of the plurality of openings extends angularly through the component from a central longitudinal opening aligned with the longitudinal axis of the component to an outer surface of the component. 
     
     
         7 . The tool as claimed in  claim 1  wherein component includes an outer surface that is frustoconical. 
     
     
         8 . The tool as claimed in  claim 1  wherein the component includes an outer surface that is rounded. 
     
     
         9 . The tool as claimed in  claim 8  wherein the rounded surface is a bull nose. 
     
     
         10 . The tool as claimed in  claim 1  wherein the component engages an outside surface of the housing mounting portion. 
     
     
         11 . The tool as claimed in  claim 1  wherein the component engages an inside surface of the housing mounting portion. 
     
     
         12 . The tool as claimed in  claim 1  wherein an engagement between the component and the housing mounting portion is by thread. 
     
     
         13 . The tool as claimed in  claim 1  wherein an engagement between the component and the housing mounting portion is by press fit. 
     
     
         14 . The tool as claimed in  claim 1  wherein an engagement between the component and the housing mounting portion is by fasteners. 
     
     
         15 . The tool as claimed in  claim 1  wherein an engagement between the component and the housing mounting portion is by adhesive. 
     
     
         16 . 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   degrading the degradable portion of the tapered nose component of the tool.   
     
     
         17 . The method as claimed in  claim 16  wherein the degrading includes applying a fluid to the tool, which fluid is configured to cause degradation of the degradable portion of the tool. 
     
     
         18 . The method as claimed in  claim 16  wherein the degrading includes allowing downhole fluids to degrade the portion of the tool that is degradable. 
     
     
         19 . 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.
