FROM PERCOLATION OF FRACTURED MEDIA TO SEISMIC ATTENUATION : A NUMERICAL STUDY

Absorption of seismic energy in fractured porous fluid-saturated media is of great interest in modern geophysics. One of mechanisms causing attenuation is the wave-induced flow (WIFF), which appears between fracture-filling material and between connected fractures. Thus, seismic attenuation estimations may serve to detect fractured fluid-filled highly permeable reservoirs. Previous study of this mechanism mostly involve quasi-static tests, or numerical wave propagation modeling with relatively simple fracture models, so further analysis of seismic attenuation on more complex systems of connected fractures is needed.
