Abstract: Deployable smart acoustic resonance particles have dense cores, compliant matrixes surrounding the cores and stiff outer shells surrounding the matrixes. The particles have mechanical stress sensitivities that provide unique band gap shifts when compressed. Groups of similar particles with similar stress sensitivities and similar band gap shifts are added at different times to hydraulic fluids, as circulated through wells with the fluid and pushed into fractures. A plural, sonic monopole well logging tool is lowered into the well to determine locations and depth of fractures and local pressures by distinct resonance of individual groups.

Abstract: Measurement data including data of a sand production rate from a sand metering sensor, pressure data from a pressure sensor, and data of a metal loss value from a metal loss sensor is obtained. A maximum sand erosional velocity ratio and a pressure drawdown are determined. An optimum choke valve setting is determined based on a predefined correlation between the sand production rate, the pressure drawdown, and the maximum sand erosional velocity ratio, in response to determining that the maximum sand erosional velocity ratio is not within a predetermined maximum sand erosional velocity ratio limit. An updated pressure drawdown produced by the determined optimum choke valve setting is within a predetermined pressure drawdown operating window. The surface choke valve is set based on the determined optimum choke valve setting. The well is shutdown by triggering an emergency shutdown device in response to determining that the obtained metal loss value has reached a predefined metal loss limit value.
