Abstract
Sensors are attached directly to portions of the sand screen of a gravel packing assembly, with connectors to the sensors run through elements of the screen that are hollow for that purpose. The hollow element can be the trapezoidal wire that is circumferentially wrapped to form the outer screen or one of the outer spacers used to provide a stand-off of the wire from the underlying tubing. Sensors can detect such conditions as pressure, temperature, flow rate, density, etc., and can provide real-time information on the effectiveness of gravel placement during packing and on well conditions during production.
