Acoustic Emission and Echo Signal Compensation Techniques Applied to an Ultrasonic Logging-While-Drilling Caliper [PDF]
Sensors, 2017 A logging-while-drilling (LWD) caliper is a tool used for the real-time measurement of a borehole diameter in oil drilling engineering. This study introduces the mechanical structure and working principle of a new LWD caliper based on ultrasonic distance

Marine and Petroleum Geology, 2019 Abstract Gas hydrates are ice-like crystalline minerals with high energy concentrations, which generally occur in deepwater environments, at low temperature and high pressure, usually close to the seafloor. Gas hydrate research wells are normally drilled riser-less, with multiple wells being drilled in rapid succession.
