Reverse flow in-flow control device
Abstract:
A fluid flow control apparatus includes a flow path that conveys the fluid into a wellbore tubular, a first passage formed along the flow path, an annular space receiving the fluid from the first passage, and a second passage receiving fluid from the annular space. The passages may flow the fluid in an axial direction along the flow path. The apparatus may include an enclosure that receives a sleeve in which the passages are formed. The annular space may be formed between the sleeve and the enclosure. The passages may include an inlet that reduces a pressure of the fluid flowing through the inlet. The passages may include a bore and may include parallel conduits. The first and the second passages may convey the fluid in a first axial direction, and the annular space may be configured to convey the fluid in a direction opposite to the first axial direction.
