Abstract
A method of monitoring fluid outflow along a wellbore includes obtaining an acoustic signal from a sensor within the wellbore, determining one or more frequency domain features from the acoustic signal, and identifying one or more fluid outflow locations along the portion of the depth of the wellbore using the one or more frequency domain features. The acoustic signal includes acoustic samples across a portion of a depth of the wellbore.
