Abstract

An apparatus includes a base pipe, a screen and a first assembly. The screen at least partially circumscribes the base pipe to create a flow path between a first region that is outside of the screen and a second region that is inside the base pipe. The flow path includes at least one radial port of the base pipe and a third region between the screen and the exterior of the base pipe. The first assembly regulates fluid communication through the flow path. The first assembly includes a second assembly that is disposed in and mounted to the base pipe and a flow control device that is slidably connected to the second assembly. The flow control device is adapted to translate between at least two positions to regulate the fluid communication through the flow path.

Claims

a second assembly disposed in and mounted to the base pipe by a fastener, the second assembly being at a fixed position with respect to the base pipe and having at least one port to enable fluid communication along the flow path; and

a flow control device adapted to regulate the fluid communication through the flow path, the flow control device comprising a sleeve slidably connected to the second assembly, the sleeve being adapted to translate between at least two positions while remaining slidably connected to the second assembly to regulate the fluid communication along the flow path.

2. The apparatus of claim 1, wherein the flow control device is adapted to be shifted between an open position in which fluid communication occurs through the flow path and a closed position in which no fluid communication occurs through the flow path.

3. The apparatus of claim 1, wherein the flow control device is adapted to be shifted between a first position associated with a first flow configuration and a second position associated with a second flow configuration.

4. The apparatus of claim 3, wherein the first flow configuration comprises a first set of radial ports associated with the fluid communication and the second flow configuration comprises a second set of radial ports associated with the fluid communication, the second set of radial ports being different from the first set of radial ports.

5. The apparatus of claim 1, wherein the flow path is selected from a group consisting essentially of a production flow path to communicate fluid from the first region outside of the screen to the second region inside the base pipe, and an injection flow path to communicate fluid from the second region inside the base pipe to the first region outside of the screen.

6. The apparatus of claim 1, wherein the second assembly comprises at least one seal to form fluid a first fluid seal between the second assembly and the base pipe and a second fluid seal between the second assembly and the flow control device.

7. The apparatus of claim 1, wherein the second assembly comprises a releasable latch to releasably retain the flow control device in a selected position associated with a selected flow through the device.

8. The apparatus of claim 7, wherein the releasable latch comprises a collet adapted to releasably engage a profile of the flow control device.

9. The apparatus of claim 1, wherein the second assembly comprises a plurality of annular segments and at least one seal, wherein the plurality of annular segments are adapted to be deployed inside the base pipe according to an assembly sequence and the at least one seal is adapted to be disposed according to the sequence between two of annular segments.

10. The apparatus of claim 1, wherein the fastener comprises at least one threaded fastener to radially extend between the base pipe and the second assembly to secure the second assembly to the base pipe.

11. The apparatus of claim 1, wherein:

the second assembly comprises a radially recessed region to receive the sleeve; and

the sleeve is adapted to translate in the radially recessed region between at least two positions associated with different flow control states of the flow control device.

12. The apparatus of claim 11, wherein:

the sleeve comprises at least one inner profile exposed on an interior surface of the sleeve; and

the inner profile being adapted to engage a shifting tool to translate the sleeve between the two positions.

13. The apparatus of claim 1, wherein the base pipe is adapted to primarily carry a longitudinal load applied to the apparatus relative to the first assembly.

14. The apparatus of claim 1, wherein the second assembly comprises an annular segment comprising at least a first radially recessed region to receive a first seal element to form a seal between the annular segment and the base pipe and at least a second radially recessed region to receive a second seal element to form a seal between the annular segment and the flow control device.

15. The apparatus of claim 1, wherein the second assembly comprises:

an annular segment comprising at least one radially recessed region to receive a first seal element to form a seal between the annular segment;

a second seal element to form a seal between the annular segment and the base pipe, wherein the second seal element is adapted to be deployed inside the base pipe after the annular segment is deployed inside the base pipe; and

a retainer to be deployed inside the base pipe after deployment of the second seal element to form a connection with the annular segment to energize the second seal element.

16. The apparatus of claim 15, wherein the retainer and the annular segment are adapted to form a threaded connection adapted to be tightened to energize the second seal element.

17. The apparatus of claim 15, wherein the second seal element comprises an inclined face adapted to energize the second seal element in response to a force acting on the inclined face due to the connection of the end cap with the annular segment.

18. The apparatus of claim 15, wherein the base pipe comprises a recessed region to receive the second seal element.

19. The apparatus of claim 15, further comprising at least one c-ring adapted to be received in the recessed region of the base pipe.

20. A method usable with a well, comprising:

inserting a fluid communication control interface into a central passageway of a base pipe of a screen assembly proximate to at least one radial port of the base pipe until the fluid communication control interface is installed inside the base pipe such that the base pipe surrounds the fluid communication control interface;

securing the fluid communication control interface to the base pipe; and

slidably mounting a sleeve to the fluid communication control interface on an opposite radial side of the fluid communication control interface relative to the base pipe such that the sleeve may be slid between positions to regulate fluid communication between the at least one radial port and the central passageway of the base pipe.

21. The method of claim 20, further comprising:

providing a latch of the interface to releasably hold the sleeve in at least one of two positions.

22. The method of claim 20, wherein inserting the fluid communication control interface comprises:
