Near-surface complexity

Seismic Speckle Modeling

Model scattering from fine-scale near-surface heterogeneity with adaptive seismic simulation.

Near-surface layers often contain slow weathered zones with fine-scale heterogeneities that scatter and distort seismic signals.

FrequenSolve localizes slow layers with adaptive meshing, enabling accurate and efficient modeling of these challenging conditions and supporting acquisition-design and processing decisions.
