Abstract
A flow control apparatus for a borehole comprises a basepipe, a screen, a sleeve, and at least one baffle. The basepipe has a bore for conveying fluid and defines at least one opening for communicating fluid into the bore. The screen is disposed on the basepipe and screens fluid from outside the basepipe. The sleeve is disposed on the basepipe adjacent the screen and has at least one flow passage for communicating the fluid from the screen to the at least one opening in the basepipe. A shelf of the sleeve extends downstream from the at least one flow passage and covers at least a portion of the basepipe upstream from the at least one opening. The at least one baffle is disposed on the shelf and changes a direction of the flow exiting from the at least one flow passage.
