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

9. A method for controlling flow through a formation and a pipe within a formation, the process comprising the steps of:
-
providing a pipe within a formation wherein the pipe comprises at least one hole extending from the ID of the pipe to the OD of the pipe;
connecting a screen to the pipe adjacent to the at least one hole of the pipe;
providing a valve to the pipe, wherein the valve is effective to control fluid flow through at least one hole of the pipe; and
providing a controller effective to adjust the position of the valve. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. An adjustable wellscreen comprising:
-
a base pipe defining a path for fluid communication to a production tubing;
a screen section effective to exclude sand from fluid flow through the screen section, the screen section essentially surrounding at least a portion of a length of the base pipe;
a volume between the screen section and the base pipe through which fluids that have flowed through the screen section may flow;
at least one valve effective to provide controllable communication between the volume between the screen section and the base pipe and the volume within the base pipe;
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 screen section 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. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
