Method of automatic characterization and removal of pad artifacts in ultrasonic images of wells
Published in United States Patent and Trademark Office, 2024
Patent application for automatic characterization and removal of pad artifacts in ultrasonic images of reservoir wells. The method estimates the artifact response from the image spectrum, derives geometric parameters for the artifact signal, models that artifact as a periodic square-wave-like signal, and filters the original well image using the resulting model.
