Abstract: A method of identifying events comprises obtaining a first set of measurements comprising a first signal of field data at a location; identifying one or more events at the location using the first set of measurements; obtaining a second set of measurements comprising a second signal at the location, wherein the first signal and the second signal represent at least one different physical measurements; training one or more event models using the second set of measurements and the identification of the one or more events as inputs; and using the one or more event models to identify at least one additional event at one or more locations.

Abstract: A method of identifying events within a wellbore comprises obtaining a first set of measurements of a first signal within a wellbore, identifying one or more events within the wellbore using the first set of measurements, obtaining a second set of measurements of a second signal within the wellbore, wherein the first signal and the second signal represent different physical measurements, training one or more event models using the second set of measurements and the identification of the one or more events as inputs, and using the one or more event models to identify at least one additional event within the wellbore.

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