Аннотация

Several seismic attenuation mechanisms in fractured porous media are currently under intense study. This notably includes pressure diffusion phenomena, such as wave-induced fluid flow (WIFF), and dynamic effects, such as scattering and Biot's global flow in fluid-filled highly permeable fractures. The effects of the former can be studied using a quasi-static approximation of Biot's poroelastic equations whereas the investigation of the latter requires simulations of wave propagation in poroelatic media. In this work, we illustrate that the diffusion effects predicted by quasi-static simulations are properly captured in the results of dynamic modelling. Our results also demonstrate that the interplay of WIFF and scattering is complex and depends on the geometry and properties of the fracture network.
