Abstract:
An oilfield production string assembled at the surface to include sensors and a controlled device, and available for testing of the sensors and device on the string from the remote end of the string before deployment downhole comprising:coil tubing carried on a reel at the surface of sufficient length to reach the desired depth downhole;a flow control device on the coiled tubing regulating flow of produced fluids from the well;a controller associated with the flow control device controlling the operation of the device and the flow of fluid therethrough;a first set of sensors monitoring downhole production parameters adjacent the flow control device; anda second set of sensors at spaced locations along the coiled tubing spaced from the flow control device, with information from one or more sensors being received at the controller and with the controller providing a control signal to the control device.
