INFLOW CONTROL DEVICE AND METHODS FOR USING SAME
First Claim
1. A completion assembly for regulating a flowrate in a wellbore, comprising:
- a base pipe;
a flow control housing disposed on the base pipe;
a first tubular port in the base pipe;
a second tubular port in fluid communication with the base pipe;
a flow control flowpath defined within the flow control housing and communicable with both the base pipe and the reservoir;
a valve assembly in fluid communication with both the reservoir and the base pipe, the valve assembly being positionable between a plurality of positions for controlling the flow through the flow control flowpath in response to fluid pressure applied to the second tubular port;
an indexing assembly for positioning the valve assembly between the plurality of positions in response to fluid pressure applied to the second tubular port.

Abstract
A completion assembly with a valve assembly for regulating fluid flow in a wellbore is disclosed. The completion assembly can include a base pipe with a sand screen. A flow control housing is disposed on one end of the sand screen. A first tubular port in the base pipe leads into the flow control housing, and a second tubular port is also formed in the base pipe. A flow path is formed within the flow control housing and communicates with both the base pipe and the inner annulus of the screen assembly. A valve assembly is located in the flow control housing and is in fluid communication with both the inner annulus and the base pipe. The valve assembly is positionable between multiple positions for controlling the flow through the flow control flowpath in response to fluid pressure applied to the second tubular port.

12. A method for regulating a flowrate in a wellbore, comprising:
-
locating a base pipe with a screen assembly disposed about the base pipe in the well bore and forming an inner annulus therebetween, the base pipe having a first tubular port disposed in a flow control housing disposed on a first end of the sand screen, the base pipe having a second tubular port disposed in a section of the base pipe separated from the flow control housing, the second tubular port communicating with a fluid control line disposed in the inner annulus beneath the screen assembly and in fluid communication with the flow control housing; locating a valve assembly into the wellbore, the valve assembly disposed in the flow control housing and in fluid communication with the inner annulus; causing a fluid to flow through the valve assembly via a flowpath in fluid communication with the base pipe and the inner annulus; positioning a service tool adjacent the second tubular port; applying fluid pressure through the service tool into the second tubular port; positioning the valve assembly between an open position where fluid flows through the flowpath between the inner annulus and the base pipe, and a closed position where fluid does not flow through the flowpath between the inner annulus and the base pipe, wherein the positioning of the valve between the open position and the closed position is in response to the step of applying fluid pressure through the service tool into the second tubular port. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A completion assembly for regulating a flowrate in a horizontal wellbore, comprising:
-
a base pipe; a filter media disposed about the base pipe, forming an inner annulus therebetween; a flow control housing disposed on a first end of the filter media; a first tubular port in the base pipe and disposed in the flow control housing; a second tubular port in the base pipe and disposed in a section of the production tubular separated from the flow control housing; a control line communicating between the second tubular port and the flow control housing, the control line extending in the inner annulus beneath the filter media; a valve assembly in fluid communication with both the inner annulus and the base pipe, the valve assembly being positionable between an open position and a closed position in response to fluid pressure applied to the second tubular port; and a flowpath defined within the flow control housing and communicable with both the base pipe and the inner annulus, wherein the flowpath comprises one or more nozzles disposed therein, and the valve assembly is configured to move between the open position allowing fluid flow through the flowpath and the closed position preventing fluid flow through the flowpath.
