Abstract
A method can include receiving real-time downhole time series sensor data during production of fluid from a well in fluid communication with a formation reservoir; transforming the real-time downhole time series sensor data to values for a set of predefined model features; detecting a downhole sand event using the values as input to a trained neural network model; and issuing a signal responsive to detection of the downhole sand event.
