Abstract
A method for measuring vibrational stresses and velocities of waves propagated within formations surrounding a wellbore essentially consists in simultaneously measuring the vibrational stress and vibrational velocity produced by propagation of the vibration within the medium, then in establishing a ratio of magnitudes relating to the vibrational stress and velocity in respect of one and the same measuring point. The method and device provided by the invention also find applications in the separation of different types of secondary waves generated during propagation of a primary wave in a medium.
