Abstract

A screen assembly including a tubular having a plurality of openings therein, a screen disposed about the tubular, and a plurality of devices disposed within the plurality of openings, the devices each including a beaded matrix and a housing. A method for completing a wellbore with a sand screen.

Claims

1. A screen assembly comprising:

a tubular having a plurality of openings therein;

a screen disposed about the tubular;

a plurality of devices disposed within the plurality of openings, the devices each including a beaded matrix and a housing.

2. The screen assembly as claimed in claim 1 wherein the housing further includes a shoulder radially outwardly located relative to the beaded matrix.

3. The screen assembly as claimed in claim 1 wherein the beaded matrix is supported by the shoulder against radially outward displacement.

4. The screen assembly as claimed in claim 1 wherein the devices will hold pressure at the inside of the tubular in excess of 3,500 PSI.

5. The screen assembly as claimed in claim 1 wherein each the devices are each receptive to a plugging configuration.

6. The screen assembly as claimed in claim 5 wherein the plugging configuration is a ball for each device.

7. The screen assembly as claimed in claim 5 wherein the plugging configuration is a material disposable within interstitial spaces within the beaded matrix.

8. The screen assembly as claimed in claim 7 wherein the material is underminable to render the beaded matrix permeable.

9. The screen assembly as claimed in claim 1 wherein each device is threadedly attached to the tubular in each opening.

10. The screen assembly as claimed in claim 9 wherein the thread is cylindrical.

11. A method for completing a wellbore with a sand screen comprising:

running a screen assembly as claimed in claim 1 into the wellbore;

plugging the plurality of devices;

pressuring up on the tubular to actuate another tool.

12. The method as claimed in claim 11 further comprising:

undermining the plugging of the plurality of devices;

establishing flow through the plurality of devices.

13. The method as claimed in claim 11 wherein the plugging occurs prior to the running.

14. The method as claimed in claim 11 wherein the plugging occurs subsequent to the running.

15. The method as claimed in claim 11 wherein the pressuring is greater than 500 PSI.

16. The method as claimed in claim 12 wherein the undermining is by applying acid to the material.

17. The method as claimed in claim 12 wherein the undermining is by durational exposure to wellbore downhole environment.

18. The method as claimed in claim 12 wherein the establishing is by straining a target fluid through the screen and flowing the target fluid through the devices.
