Adaptive Acoustic Pulse Shaping for Distance Measurements

Adaptive Acoustic Pulse Shaping for Distance Measurements

A method to measure the fluid depth in a wellbore is described. An optimized acoustic pulse stream is launched into the wellbore, and the round-trip time-of-flight between the fluid surface and the top of the wellbore is measured. The method provides improved signal to noise ratio, and can be active...

Zusammenfassung:A method to measure the fluid depth in a wellbore is described. An optimized acoustic pulse stream is launched into the wellbore, and the round-trip time-of-flight between the fluid surface and the top of the wellbore is measured. The method provides improved signal to noise ratio, and can be actively tuned to a plurality of wellbore configurations.
