Poroelastic Modelling of Wavefields in Heterogeneous Media. Poroelastische Modellierung von Wellenfeldern in Heterogenen Medien
Abstract:
Numerical modelling of seismic waves in heterogeneous, porous reservoir rocks is an important tool in the field of reservoir engineering. A new 2-D velocity-stress finite-differences scheme is presented that allows to simulate waves and coupled diffusion processes within poroelastic media as described by Biot theory. The presented numerical methods allow to further develop rock physics theories of wave-induced fluid flow and contribute to the interpretation of new laboratory experiments.
