Abstract: Methods and system of characterizing perforations in a tubular. An imaging tool having an acoustic imaging probe transmits waves and receives acoustic reflections from the tubular. Image segments are processed from the acoustic data. A first trained neural network operates on the image segments to identify processed image segments containing a perforation. A second trained neural network operates on processed image segments containing a perforation to output the location of perforations along the tubular. Another trained neural network can calculate a geometric size of the perforations, such as their size or points along their contour.
