3D seismic imaging and characterization of heterogeneous fractures

/0 Comments/in /by

In our recent works [65,66], we demonstrate via the frameworks of linear sampling and boundary integral equations the feasibility of non-iterative, 3D seismic waveform tomography of heterogeneous fractures. This includes both (i) geometric fracture reconstruction and (ii) quantitative mapping of its shear and normal specific stiffness distributions — reflecting e.g. the fracture aperture, surface roughness, […]
