Abstract

A through tubing intelligent completion including a completion string; one or more isolation seals on the completion string and having an undeployed set of dimensions smaller than one or more restrictions in a tubing string through which the completion string is deployed; and one or more interventionlessly actuable flow control devices in the completion string having a set of dimensions smaller than one or more restrictions in a tubing string through which the completion string is deployed and method.

Claims

1. A through tubing intelligent completion comprising:

a completion string;

one or more isolation seals on the completion string and having an undeployed set of dimensions smaller than one or more restrictions in a tubing string through which the completion string is deployed; and

one or more interventionlessly actuable flow control devices in the completion string having a set of dimensions smaller than one or more restrictions in a tubing string through which the completion string is deployed.

2. A through tubing intelligent completion as claimed in claim 1 further comprising a control line in operable communication with one or more of the one or more interventionlessly actuable flow control devices.

3. A through tubing intelligent completion as claimed in claim 1 wherein the one or more isolation seals are inflatable seals.

4. A through tubing intelligent completion as claimed in claim 1 wherein the one or more isolation seals are swellable seals.

5. A through tubing intelligent completion as claimed in claim 1 wherein the one or more interventionlessly actuable flow control devices comprises:

a housing;

a fluid bypass channel within the housing;

an actuator within the housing; and

a valve in operable communication with the actuator.

6. A through tubing intelligent completion as claimed in claim 5 wherein the actuator is disposed centrally of the housing.

7. A through tubing intelligent completion as claimed in claim 5 wherein the bypass is disposed perimetrically of the housing relative to the actuator.

8. A through tubing intelligent completion as claimed in claim 5 wherein the valve is a poppet type valve.

9. A through tubing intelligent completion as claimed in claim 1 wherein the completion string further includes a wet connect.

10. A through tubing intelligent completion as claimed in claim 1 wherein the completion string further includes one or more sensors.

11. A through tubing intelligent completion as claimed in claim 1 wherein the completion string further includes a set of one or more ports fluidly communicating the completion string with an annuls thereof.

12. A method for upgrading an existing well with an intelligent completion comprising:

making up a completion string as defined in claim 1;

running the completion string into a production tubing string in a borehole;

exiting a downhole end of the production tubing string with the completion string; and

deploying the one of more isolation seals.

13. A method as claimed in claim 12 further comprising adjusting one or more of the one or more control devices to optimize production.

14. A method as claimed in claim 12 wherein the running is on coil tubing.

15. A method as claimed in claim 12 wherein the deploying is by inflating the one or more seals.

16. A method as claimed in claim 12 wherein the deploying is by swelling the one or more seals.
