Abstract
Methods and systems for determining formation properties in subsurface operations include drilling into a formation with a disintegrating device disposed on a downhole string, monitoring dynamics information signals in the downhole string with a dynamics information sensor to obtain dynamics information data, applying a transfer function to the dynamics information data to obtain a dynamics information signature, and analyzing the dynamics information signature to determine a formation property of the formation drilled by the disintegrating device.
