Abstract
Methods, systems, and techniques for determining whether an acoustic event has occurred along a fluid conduit having acoustic sensors positioned therealong. The method uses a processor to, for each of the sensors, determine a predicted acoustic signal using one or more past acoustic signals measured prior to measuring a measured acoustic signal using the sensor; determine a prediction error between the measured acoustic signal and the predicted acoustic signal; from the prediction error, determine a power estimate of an acoustic source located along a longitudinal segment of the fluid conduit overlapping the sensor; and determine whether the power estimate of the acoustic source exceeds an event threshold for the sensor. When the power estimate of at least one of the acoustic sources exceeds the event threshold, the processor attributes the acoustic event to one of the sensors for which the power estimate of the acoustic source exceeds the event threshold.
