ULTRASONIC WAVEFORM PROCESSING USING DECONVOLUTION IN DOWNHOLE ENVIRONMENTS

Deconvolution-based processing of ultrasonic waveforms enables robust calculation of two-way travel time for an ultrasonic caliper, particularly in the presence of multiple, proximal reflectors (e.g., mud cake, formation, casing, cement, etc.).
