Abstract

A well screen can include multiple filter section ends, the filter section ends being displaced outward in response to expansion of the well screen, and a slurry delivery shunt conduit positioned circumferentially between the filter section ends. A method of delivering a slurry into a wellbore about a well screen can include positioning slurry delivery shunt conduits between multiple circumferentially spaced apart filter sections of the well screen, the filter sections radially outwardly displacing in a well, and flowing the slurry through the shunt conduits. A well system can include multiple well screens positioned in a wellbore, and shunt conduits which deliver a slurry into the wellbore about the well screens, the shunt conduits being positioned circumferentially between filter sections of the well screens.

First claim

What is claimed is:

1 . A well screen, comprising:
multiple filter section ends, the filter section ends being displaced outward in response to expansion of the well screen; and a slurry delivery shunt conduit positioned circumferentially between the filter section ends.

2 . The well screen of claim 1 , wherein the multiple filter section ends are included in at least one filter section that is displaced outward in response to the expansion of the well screen.

3 . The well screen of claim 1 , wherein the multiple filter section ends are included in multiple respective filter sections that are displaced radially outward in response to the expansion of the well screen.

4 . The well screen of claim 3 , wherein the filter sections are displaced outward by a material which swells in response to contact with a fluid in a well.

5 . The well screen of claim 1 , wherein the well screen expands in response to contact between a swellable material and a fluid in a well.

6 . The well screen of claim 1 , wherein the shunt conduit displaces outward in response to the expansion of the well screen.

7 . The well screen of claim 1 , wherein the slurry flows outward from the shunt conduit via a nozzle connected to the shunt conduit.

8 . A method of delivering a slurry into a wellbore about a well screen, the method comprising:
positioning slurry delivery shunt conduits between multiple circumferentially spaced apart filter sections of the well screen; the filter sections radially outwardly displacing in a well; and flowing the slurry through the shunt conduits.

9 . The method of claim 8 , wherein the outwardly displacing further comprises a material swelling in response to contact with a fluid in the well.

10 . The method of claim 8 , wherein the outwardly displacing further comprises the shunt conduits outwardly displacing with the filter sections.

11 . The method of claim 8 , wherein the flowing further comprises flowing the slurry outward from the shunt conduits between the filter sections.

12 . The method of claim 8 , wherein the shunt conduits are positioned circumferentially between the filter sections.

13 . The method of claim 8 , wherein the flowing further comprises flowing the slurry outward from the shunt conduits via nozzles connected to the shunt conduits.

14 . A well system, comprising:
multiple well screens positioned in a wellbore; and shunt conduits which deliver a slurry into the wellbore about the well screens, the shunt conduits being positioned circumferentially between filter sections of the well screens.

15 . The system of claim 14 , wherein the filter sections are displaced outward in response to expansion of the well screens.

16 . The system of claim 15 , wherein the filter sections are displaced outward by a material which swells in response to contact with a fluid in the wellbore.

17 . The system of claim 14 , wherein the well screens expand in response to contact between a swellable material and a fluid in the wellbore.

18 . The system of claim 14 , wherein the shunt conduit displaces outward in response to expansion of the well screen.

19 . The system of claim 14 , wherein the slurry flows outward from the shunt conduits between the filter sections.

20 . The system of claim 14 , wherein the slurry flows outward from the shunt conduits via nozzles connected to the shunt conduits.
