Study on Time-of-Flight Estimation in Ultrasonic Well Logging Tool: Model-Driven Transfer Learning

Time-of-flight (ToF) of ultrasonic waves is essential for petroleum well logging to draw borehole-wall images. This paper proposed a method that boosted accuracy of ToFs estimation in a complex geological environment. Unlike other classical methods, the proposed one adopts a one-dimensional convolut…
