Abstract

Oscillatory fluid flow in deformable porous media induced by seismic waves is associated with dissipation. Though this dissipation is typically described through macroscopic equations, it has its origin in the fluid phase enclosed in the pore space of the rock. Therefore simulating fluid flow at the pore-scale provides a means to get further insight into the mechanism of wave-induced flow. In this paper we use the finite volume method to simulate oscillatory fluid flow in a small sub-volume of rock sample digitized at micro-meter resolution. The aim is to quantify the amount of dissipation at pore-scale and to relate it to the frequency of the periodic input signal (a proxy for the propagating wave).
