WebSummary The Earth interior contains heterogeneities at all scales, ranging from pores and mineral grains to major global units. On the contrary, seismic recordings only contain variations larger than the minimum wavelength λmin. The heterogeneities smaller than λmin are naturally smoothed by the wavefield, leading to effective media when inverting … WebThis is a direct acoustic simulation with the SEG/EAGE Overthrust seismic model, obtained by solving the Helmholtz equation. The problem is discretized with P2 Lagrange finite elements, with 5 mesh points per wavelength.
