New technique for the land seismic exploration in the Middle East.

What is it about?

Full waveform inversion is the most advanced imaging tools in both exploration geophysics and global seismology. Yet, its application on land seismic data is quite challenging due to the complicated waveforms and complex subsurface geologic structures. We propose an efficient inversion strategy in this study: a successful inversion could be achieved by combining these factors (1) a suitable parameterization, (2) an advanced objective function. We take into account realistic wave propagation effects by adding seismic anisotropy parameters. We start from fundamental theory, and conduct numerical experiments. Finally, we confirm the effectiveness of our inversion strategy. Then, we apply our inversion to a real land seismic data. Our inversion results show reasonable geologic structures. Our inversion indicates that the near surface area is quite anisotropic.

Why is it important?

We came up a new workflow to deal with the land seismic data. It is the first time an elastic full waveform inversion has been applied to real data.
