Abstract
Remotely controllable fluid flow control valves are disposed in the main wellbore and branch wellbores of a multiple well. Each flow control valve has a radio frequency range receiver, a controller and an actuator for moving a closure member to a selected position to control fluid flow in the wellbore in which the valve is disposed. A signal transmitter may be conveyed into the main wellbore by an E-line or coilable tubing and radio frequency range electromagnetic wave energy signals may be transmitted to the selected valve to effect fluid flow control within each wellbore of the multiple well. The remotely controllable valves eliminate expensive and difficult procedures associated with reentering branch wells extending from a central or main wellbore.
