Abstract
Methods and apparatus provides an improved shunt nozzle which is part of an alternative pathway for a slurry to by-pass an obstruction such as a sand bridge during gravel packing. The nozzle includes a hardened insert that lines a surface of an aperture in a shunt. A jacket secured to the shunt receives the insert, which is trapped from movement relative to the jacket.
Claims37
A nozzle assembly for use in a gravel pack tool having an aperture through a wall of a shunt along the tool, comprising:
- an insert having a proximal end at least partially lining the aperture, wherein the insert has an outward facing shoulder distal to the aperture;
- and
- a jacket concentrically surrounding the insert, wherein the jacket is secured to an outer surface of the wall and has a face in abutment with the shoulder, wherein the shoulder of the insert is trapped against the face of the jacket to prevent movement of the insert into the aperture.
An apparatus for use in a wellbore, comprising:
- a wellscreen assembly;
- at least one shunt disposed on the wellscreen assembly and having an aperture through a wall of the shunt;
- an insert having a proximal end at least partially lining the aperture, wherein the insert has an outward facing shoulder distal to the aperture;
- a jacket concentrically surrounding the insert, wherein a first end of the jacket is secured to an outer surface of the wall and a second end of the jacket terminates in abutting contact with the shoulder;
- and
- an open cap secured to the jacket, wherein an inward facing shoulder of the cap abuts a distal terminus of the insert.
A nozzle assembly for use in a gravel pack tool having an aperture through a wall of a shunt along the tool, comprising:
- an insert having a proximal end at least partially lining the aperture, wherein the insert has an enlarged outer diameter at a distal end of the insert relative to the aperture;
- a jacket concentrically surrounding the insert, wherein the jacket is secured to an outer surface of the wall at a first end and has an inner diameter smaller than the enlarged outer diameter of the insert, which abuts a second end of the jacket at the enlarged outer diameter;
- and
- an open cap secured to the second end of the jacket and extending beyond the enlarged outer diameter of the insert, wherein an opening through the cap has a restricted diameter smaller than the enlarged outer diameter of the insert, which is thereby trapped relative to the jacket.
A nozzle assembly for use in a gravel pack tool having an aperture through a wall of a shunt along the tool, comprising:
- an insert having a proximal end at least partially lining the aperture, wherein the insert has an outward facing shoulder distal to the aperture;
- and
- a jacket concentrically surrounding the insert, wherein the jacket is secured to an outer surface of the wall and has a face in abutment with the shoulder, wherein the insert is longer than the jacket.
A nozzle assembly for use in a gravel pack tool having an aperture through a wall of a shunt along the tool, comprising:
- an insert having a proximal end at least partially lining the aperture, wherein the insert has an outward facing shoulder distal to the aperture;
- and
- a jacket concentrically surrounding the insert, wherein the jacket is secured to an outer surface of the wall and has a face in abutment with the shoulder, wherein the face of the jacket is a distal terminus of the jacket.
A nozzle assembly for use in a gravel pack tool having an aperture through a wall of a shunt along the tool, comprising:
- an insert having a proximal end at least partially lining the aperture, wherein the insert has an outward facing shoulder distal to the aperture;
- a jacket concentrically surrounding the insert, wherein the jacket is secured to an outer surface of the wall and has a face in abutment with the shoulder;
- and
- an open cap secured to an outer surface of the jacket at a distal end of the jacket, wherein the outward facing shoulder is disposed between an inward facing shoulder of the cap and the face of the jacket.
A nozzle assembly for use in a gravel pack tool having an aperture through a wall of a shunt along the tool, comprising:
- an insert having a proximal end at least partially lining the aperture, wherein the insert has an outward facing shoulder distal to the aperture;
- a jacket concentrically surrounding the insert, wherein the jacket is secured to an outer surface of the wall and has a face in abutment with the shoulder;
- and
- an open cap threaded to an outer surface of the jacket, wherein the outward facing shoulder is disposed between an inward facing shoulder of the cap and the face of the jacket.
A nozzle assembly for use in a gravel pack tool having an aperture through a wall of a shunt along the tool, comprising:
- an insert having a proximal end at least partially lining the aperture, wherein the insert has an outward facing shoulder distal to the aperture;
- a jacket concentrically surrounding the insert, wherein the jacket is secured to an outer surface of the wall and has a face in abutment with the shoulder;
- and
- an annular cap secured to a distal end of the jacket and having an inward facing shoulder abutting a distal terminus of the insert.
A nozzle assembly for use in a gravel pack tool having an aperture through a wall of a shunt along the tool, comprising:
- an insert having a proximal end at least partially lining the aperture, wherein the insert has an outward facing shoulder distal to the aperture;
- and
- a jacket concentrically surrounding the insert, wherein the jacket is secured to an outer surface of the wall and has a face in abutment with the shoulder, wherein the insert is removable without removing the jacket from the tool.
