Seismic Imaging and Inversion Techniques

Seismic imaging and inversion techniques use recordings of elastic waves—generated by earthquakes or controlled sources—to reconstruct the internal structure and material properties of the Earth's subsurface. By solving the inverse problem of matching observed waveforms to synthetic ones computed from candidate Earth models, researchers can recover detailed maps of rock density, velocity, and anisotropy at scales ranging from hydrocarbon reservoirs to the deep mantle. Full-waveform inversion, which exploits the complete information content of recorded seismograms rather than just arrival times, has become a central focus, though it remains computationally demanding and prone to converging on incorrect solutions when starting models are too far from the truth. Active research directions include handling frequency-dependent anisotropy more rigorously, integrating rock-physics constraints to make recovered models physically interpretable, and developing more efficient adjoint-based optimization schemes that can scale to three-dimensional, high-resolution targets.
