Paper presented at the International Geomechanics Symposium, October 30–November 2, 2023
Paper Number: ARMA-IGS-2023-0200
..., recording the sound of the drill bit and analyzing its characteristics, such as frequency and amplitude, can reveal information about lithology in real time. A system, hardware and software, is developed to record and process the drill bit sounds in real time. The key challenge in utilizing the sound...

Paper Number: ARMA-IGS-2022-006
... the stability of wellbore. The influences of waveform, mean pressure, amplitude, period, and cycle number of the dynamic wellbore pressure wave on wellbore stability were simulated and discussed. The results indicated that the equivalent plastic strain and NYZA increased significantly when the dynamic wellbore...
