Abstract

A well screen assembly includes a tubing including a center bore and at least one aperture through the tubing between an outer radial surface of the tubing and an inner radial surface of the tubing; a filtration screen positioned around the tubing; a housing positioned around the tubing and including a fluid chamber in fluid communication with an outlet of the filtration screen; and a flow control device positioned in fluid communication with the outlet of the filtration screen and the at least one aperture to reduce a wall shear stress on at least one of the tubing or the at least one aperture.

First claim

1 . A well screen assembly, comprising:
a tubing comprising a center bore and at least one aperture through the tubing between an outer radial surface of the tubing and an inner radial surface of the tubing; a filtration screen positioned around the tubing; a housing positioned around the tubing and comprising a fluid chamber in fluid communication with an outlet of the filtration screen; and a flow control device positioned in fluid communication with the outlet of the filtration screen and the at least one aperture to reduce a wall shear stress on at least one of the tubing or the at least one aperture.

2 . The well screen assembly of claim 1 , wherein the flow control device comprises a tubular sleeve positioned around the tubing adjacent the at least one aperture.

3 . The well screen assembly of claim 2 , wherein the tubular sleeve comprises a perforation therethrough to allow fluid communication from the outlet of the filtration screen, through the tubular sleeve, and to the at least one aperture.

4 . The well screen assembly of claim 3 , wherein the perforation is radially offset from the at least one aperture.

5 . The well screen assembly of claim 2 , wherein the tubular sleeve comprises a plurality of perforations.

6 . The well screen assembly of claim 1 , further comprising a fluid conduit that extends through the housing and is fluidly coupled between the outlet of the filtration screen and the fluid chamber.

7 . The well screen assembly of claim 1 , wherein the fluid conduit comprises an inlet adjacent the outlet of the filtration screen and an outlet adjacent the fluid chamber, the outlet of the fluid conduit comprising a slope from the fluid conduit toward the at least one aperture.

8 . The well screen assembly of claim 1 , wherein the flow control device comprises an outlet of the fluid chamber equal in size to the at least one aperture.

9 . The well screen assembly of claim 8 , wherein the outlet of the fluid chamber comprises a one inch diameter circular opening.

10 . The well screen assembly of claim 1 , wherein the flow control device comprises a lip that extends axially from an inner surface of the housing and radially around the tubing adjacent the at least one aperture.

11 . The well screen assembly of claim 10 , wherein the lip slopes toward the at least one aperture.

12 . The well screen assembly of claim 1 , wherein the flow control device comprises a shape of the at least one aperture, the shape comprising:
a throughbore, from the outer radial surface to the inner radial surface, that is angled relative to the center bore; or a throughbore comprising an inlet at the outer radial surface and an outlet at the inner radial surface, the inlet larger than the outlet.

13 . The well screen assembly of claim 12 , wherein the inlet of the throughbore comprises a circular inlet or an oval inlet.

14 . The well screen assembly of claim 1 , wherein the flow control device comprises an insertable liner positioned in the at least one aperture.

15 . A method for reducing a wall shear stress of a well screen assembly, comprising:
receiving a flow of a wellbore fluid through a filtration screen positioned around a tubular member, the tubular member comprising a center bore and at least one aperture through the tubular; directing the wellbore fluid from an outlet of the filtration screen into a fluid chamber of a housing positioned around the tubing; directing the wellbore fluid through the at least one aperture to the center bore of the tubular member; and reducing a wall shear stress on at least one of the tubular member or the at least one aperture from the wellbore fluid directed from the outlet of the filtration screen through the at least one aperture.

16 . The method of claim 15 , wherein reducing a wall shear stress on at least one of the tubular member or the at least one aperture comprises:
directing the wellbore fluid over a tubular sleeve positioned around the tubular member adjacent the at least one aperture.

17 . The method of claim 16 , further comprising directing the wellbore fluid through a perforation in the tubular sleeve and then to the at least one aperture.

18 . The method of claim 17 , wherein the perforation is radially offset from the at least one aperture.

19 . The method of claim 16 , further comprising directing the wellbore fluid through a plurality of perforations in the tubular sleeve and then to the at least one aperture.

20 .- 27 . (canceled)

28 . An inflow control device (ICD) for a wellbore fluid, comprising:
a base pipe that comprises a bore and a plurality of perforations; a filter screen wrapped around a portion of the base pipe to fluidly couple the bore with a wellbore annulus; a housing coupled to the filter screen and wrapped around the base pipe, the housing comprising a flow path that is in fluid communication with the filter screen and the plurality of perforations; and a tubular sleeve that covers a portion of the base pipe to fluidly isolate the portion of the base pipe from the flow path.

29 .- 35 . (canceled)

36 . The ICD of claim 28 , wherein at least one of the plurality of perforations comprises a fluid path that extends between an outer radial surface of the base pipe and an inner radial surface of the base pipe, the fluid path comprising a funnel.
