First Claim
Patent Images
1. A method for controlling flow through a formation and a pipe within a formation, the process comprising the steps of:
- providing a base pipe having an upper end and a lower end;
providing an upper screen attached concentrically around the upper end of the base pipe;
providing a lower screen attached concentrically around the lower end of the base pipe;
providing a valve located between the upper screen and the lower screen; and
providing a valve screen attached concentrically around the valve, wherein the diameter the valve screen is greater than the diameter of the upper screen and the lower screen;
providing a valve motor mechanically connected to said valve, wherein said valve motor opens and closes said valve; and
providing a valve controller communicatively connected to said valve motor, wherein said valve controller instructs the valve motor as to a configuration of the valve.

Abstract
An adjustable well screen assembly having a pipe which is connectable to a production pipe, wherein the pipe comprises a hole extending from the ID of the pipe to the OD of the pipe; a screen connected to the pipe adjacent the hole of the pipe; a valve connected to the pipe, wherein the valve controls fluid flow through the hole of the pipe; a valve motor mechanically connected to the valve, wherein the valve motor opens and closes the valve; and a valve controller communicatively connected to the valve motor, wherein the valve controller instructs the valve motor as to a configuration of the valve.

9. An adjustable wellscreen comprising:
-
a base pipe defining a path for fluid communication to a production tubing; at least one valve; an upper screen located above the valve surrounding at least a portion of the length of the base pipe; a valve screen surrounding at least a portion of the valve; a lower screen located below the valve surrounding at least a portion of the length of the base pipe; a volume defined between the valve screen and the base pipe into which fluids that have flowed through any screen may flow; at least one valve motor effective to change the position of the valve; at least one sensor effective to determine a physical condition of fluids near the valve and to provide a signal indicative of that physical condition; and a controller effective to command the valve motor to change the position of the valve in response to the signal from the sensor; wherein the valve is effective to provide controllable communication between the volume and the interior of the base pipe. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)
