SPE Drill & Compl 31 (02): 106–118.
Paper Number: SPE-170713-PA
Published: 03 May 2016
.... Several cases were studied to investigate the evolution and response of drilling-system behavior on the basis of in-depth interpretation of relatively long durations (minutes to hours) of HF data sets in the operational context. The findings verify the value of using continuous HF vibration data...
