Abstract

In one aspect, a device for use in a wellbore includes a tubular body; a barrier member associated with an outer surface of the tubular body configured to retain a proppant; an actuating member associated with the barrier member configured to expand the barrier member in an annular direction; and a fluid channel associated with an upper extent and a lower extent of the barrier member, configured to allow a fluid flow therethrough. In another aspect, a method for completing a multi-zone wellbore, includes deploying a barrier device at a downhole location within the wellbore; expanding a barrier member in an annulus of the wellbore; providing proppant in the annulus of the wellbore; retaining the proppant in the annulus via the barrier member; and providing a fluid flow between an upper extent and a lower extent of the barrier member.

First claim

The invention claimed is:

1. A device for use in a wellbore, comprising:
a tubular body defining an annulus in the wellbore;
a barrier member associated with an outer surface of the tubular body configured to retain a proppant, wherein the barrier is deployed in the wellbore by the tubular member;
an actuating member associated with the barrier member configured to expand the barrier member in an annular direction; and
a fluid channel disposed between the barrier member and the outer surface of the tubular body with an upper channel opening disposed above the barrier member for fluid communication with the annulus and a lower channel opening disposed below the barrier member for fluid communication with the annulus, the fluid channel configured to allow a fluid flow therethrough;
wherein the actuating member includes an opening that is aligned with the upper channel opening of the fluid channel when the barrier member is expanded and is non-aligned with the upper channel opening when the barrier member is not expanded.

2. The device of claim 1 , wherein the actuating member includes a piston in fluid communication with a tubular pressure associated with the tubular body.

3. The device of claim 1 , wherein the actuating member includes a locking member configured to retain a position of the actuating member.

4. The device of claim 1 , wherein the actuating member includes a shear member configured to retain an initial position of the actuating member up to a predetermined force.

5. The device of claim 1 , wherein the fluid channel is disposed within the barrier member.

6. The device of claim 1 , wherein the fluid channel is disposed between the outer surface of the tubular body and the barrier member.

7. A system for use in a wellbore, comprising:
a tubing string;
a service tool configured to provide a proppant in an annulus around the tubing string; and
a barrier device comprising:
a tubular body associated with the tubing string, the tubular body defining an annulus in the wellbore, wherein the barrier is deployed in the wellbore by the tubular member;
a barrier member associated with an outer surface of the tubular body configured to retain the proppant;
an actuating member associated with the barrier member configured to expand the barrier member in the annulus; and
a fluid channel disposed between the barrier member and the outer surface of the tubular body with an upper channel opening disposed above the barrier member for fluid communication with the annulus and a lower channel opening disposed below the barrier member for fluid communication with the annulus, the fluid channel configured to allow a fluid flow therethrough;
wherein the actuating member includes an opening that is aligned with the upper channel opening of the fluid channel when the barrier member is expanded and is non-aligned with the upper channel opening when the barrier member is not expanded.

8. The system of claim 7 , wherein the actuating member includes a piston in fluid communication with a tubular pressure associated with the tubular body.

9. The system of claim 7 , wherein the actuating member includes a locking member configured to retain a position of the actuating member.

10. The system of claim 7 , wherein the actuating member includes a shear member configured to retain an initial position of the actuating member up to a predetermined force.

11. The system of claim 7 , wherein the fluid channel is disposed within the barrier member.

12. The system of claim 7 , wherein the fluid channel is disposed between the outer surface of the tubular body and the barrier member.

13. The system of claim 7 , wherein the barrier device is disposed immediately downhole of an initial production zone.

14. The system of claim 13 , wherein the barrier device is disposed above a downhole production zone disposed below the initial production zone.

15. A method for completing a multi-zone wellbore, comprising:
deploying a barrier device at a downhole location via a tubular body within the wellbore wherein the tubular body defines an annulus in the wellbore:
expanding a barrier member of the barrier device into the annulus of the wellbore via an actuating member;
providing proppant in the annulus of the wellbore;
retaining the proppant in the annulus via the barrier member; and
providing a fluid flow in a channel disposed between the barrier member and the outer surface of the tubular body with an upper channel opening disposed above the barrier member for fluid communication with the annulus and a lower channel opening disposed below the barrier member for fluid communication with the annulus;
wherein the actuating member includes an opening that is aligned with the upper channel opening of the fluid channel when the barrier member is expanded and is non-aligned with the upper channel opening when the barrier member is not expanded.

16. The method of claim 15 , further comprising deploying the barrier device immediately downhole of an initial production zone.

17. The method of claim 16 , further comprising deploying the barrier device above a downhole production zone disposed below the initial production zone.

18. The method of claim 15 , further comprising providing a tubular pressure to a piston associated with the barrier member.

19. The method of claim 18 , further comprising resisting an expansion of the barrier member until a predetermined force is applied to the piston.

20. The method of claim 15 , further comprising retaining an expansion of the barrier member.
