A method for cleaning and/or altering an inside surface and shape of a tubular in a wellbore. The method includes placing a surface finishing tool in the tubular, energizing the surface finishing tool, and causing extendable assemblies therein to extend radially to contact an inside diameter of the tubular. Moving the surface finishing tool axially and/or rotationally while the extended members are in contact with the inside diameter of the tubular cleans debris from the inside surface of the tubular. In another aspect of the invention, the tool burnishes the inside diameter of the tubular, thereby altering the surface characteristics and rounding the tubular.

1. A method of cleaning an inside diameter of a downhole tubular in a wellbore, comprising:running the tubular into the wellbore;running a workstring into the tubular, the workstring including a surface finishing tool at the end thereof, the tool having at least one radially extendable assembly moun
1. A method of cleaning an inside diameter of a downhole tubular in a wellbore, comprising:running the tubular into the wellbore;running a workstring into the tubular, the workstring including a surface finishing tool at the end thereof, the tool having at least one radially extendable assembly mounted thereon;energizing the surface finishing tool and causing the at least one extendable assembly therein to extend radially to contact the inside diameter of the tubular; andmoving the tool within the tubular, thereby cleaning the inside diameter. 2. The method of claim 1, wherein the moving includes axial movement of the tool relative to the wellbore. 3. The method of claim 1, wherein the moving includes rotational movement of the tool relative to the wellbore. 4. The method of claim 1, wherein the moving includes axial and rotational movement of the tool relative to the wellbore. 5. The method of claim 1, wherein the workstring is coiled tubing. 6. The method of claim 5, wherein rotational movement of the tool within the tubular is accomplished by a mud motor disposed on the coiled tubing above the tool. 7. The method of claim 1, wherein the at least one extendable assembly includes a roller for contacting the inside diameter. 8. The method of claim 1, wherein the at least one or more extendable assembly includes at least one member having an edge formed thereupon, the edge constructed and arranged to contact and remove material disposed on the inside diameter. 9. A method of altering an inside surface of a downhole tubular in a wellbore, comprising:running the tubular into the wellbore;running a workstring into the tubular the workstring including a surface finishing tool at the end thereof, the tool having at least one radially extendable assembly mounted thereon;energizing the surface finishing tool and causing the extendable assemblies therein to extend radially to contact the inside surface of the tubular; andmoving the tool within the tubular member, thereby altering the inside surface. 10. The method of claim 9, wherein altering the inside surface includes reforming the surface into a more uniformly round shape. 11. The method of claim 9, wherein altering the inside surface includes burnishing the inside surface of the tubular. 12. The method of claim 9, wherein altering the inside surface includes reforming the surface into a more uniformly round shape and burnishing the inside surface, thereby forming a polished bore receptacle. 13. The method of claim 9, wherein the moving includes axial movement of the tool relative to the wellbore. 14. The method of claim 9, wherein the moving includes rotational movement of the tool relative to the wellbore. 15. The method of claim 9, wherein the moving includes axial and rotational movement of the tool relative to the wellbore. 16. The method of claim 9, wherein the workstring is coiled tubing. 17. The method of claim 16, wherein rotational movement of the tool within the tubular is accomplished by a mud motor disposed on the coiled tubing above the tool. 18. A method of cleaning an inside diameter of a downhole tubular in a wellbore, comprising:placing a surface finishing tool in the downhole tubular, the surface finishing tool is disposed on coiled tubing and the surface finishing tool having at least one radially extendable assembly mounted thereon;energizing the surface finishing tool and causing the at least one radially extendable assembly therein to extend radially to contact the inside diameter of the downhole tubular; andmoving the surface finishing tool within the downhole tubular, thereby cleaning the inside diameter. 19. A method of altering an inside surface of a downhole tubular in a wellbore, comprising:placing a surface finishing tool in the tubular, the surface finishing tool is disposed on a tubular string and the surface finishing tool having at least one radially extendable assembly mounted thereon;energizing the surface finishing tool and causing the extendabl e assemblies therein to extend radially to contact the inside surface of the tubular; andmoving the tool within the tubular member, thereby altering the inside surface, wherein altering the inside surface includes burnishing the inside surface of the tubular. 20. The method of claim 19, wherein altering the inside surface further includes reforming the surface into a more uniformly round shape, thereby forming a polished bore receptacle. 21. The method of claim 19, wherein the at least one radially extendable assembly includes at least one roller. 22. A method of conditioning an inside diameter of a downhole tubular in a wellbore, comprising:placing a surface finishing toll in the downhole tubular, the surface finishing toll is diposed on coiled tubing and the surface finishing tool having at least one radially extendable assembly mounted thereon;energizing the surface finishing toll and causing the at least one radially extendable assembly therein to extend radially to contact the inside diameter of the downhole tubular; andmoving the surface finishing tool within the downhole tubular, thereby conditioning the inside diameter.
