The effect of pore pressure changes on seismic wave propagation was examined using a dual simulation of fluid flow and seismic propagation in a common fracture network. It was found that P-waves are not as sensitive to pore pressure changes as S-waves or coda waves. The increase in pore pressure caused a shift of the energy toward lower frequencies. Furthermore, fluid effects on the wavefield significantly varied with the source-receiver direction.
