Kinematic and dynamic characteristics of seismic pulses in porous-fractured rocks with effective spatial wave dispersion
This work concerns with seismic pulses propagation in porous-fractured rocks. Such geological media could possess strong macroscopic spatial dispersion of seismic waves.

| description | This work concerns with seismic pulses propagation in porous-fractured rocks. Such geological media could possess strong macroscopic spatial dispersion of seismic waves. Results of physical modelling are compared with theoretical estimations of group velocities based on linear slip model of fluid-saturated fracture. They are in good agreement. Computer 3D full waveform simulation of compressional pulses reflection on the boundary of isotropic and transverse isotropic media with horizontal symmetry axis provide a validation that use of group velocities instead of phase ones raises accuracy of the Rueger's approximate equations when concerning utilized in practice seismic signals. |
