We believe Full waveform inversion (FWI) is capable to be used as a part of seismic data processing routines. In order to check the possibility of using FWI in conventional data processing sequences, we evaluated the effect of different initial model

In the Seafloor Massive Sulfide (SMS) exploration, the buried sulfide deposits without hydrothermal activity are important for mining development. We had proposed Vertical Cable Seismic (VCS) for exploration of SMS and found out it could reveal the b

Full waveform inversion requires a good initial model in order to converge to the correct solution. Most of the methods which develop initial velocity model either require times or additional source of data, e.g. travel time tomography, migration vel

Summary Full Waveform Inversion (FWI) of seismic data is a high resolution subsurface imaging tool and there is a lot of effort to fully industrialize it. The method, which uses a gradient based data fitting approach to minimize the misfit between ob

Initializing the Full Waveform Inversion (FWI) iterations from sufficiently low frequencies through a multiscale scheme provides long wavelength information in the early stages of FWI and yields the convergence to the correct solution of the problem.

Full waveform inversion (FWI) of seismic reflection data has been widely used with different 2D/3D data acquisiton geometries. The method develops a reliable subsurface model by minimizing misfit between observed and simulated waveforms. Vertical Cab

The Vertical Cable Seismic (VCS) survey is one of the reflection seismic methods. It uses hydrophone arrays vertically moored from the seafloor to record acoustic waves generated by seismic sources. Because the VCS is an efficient high-resolution 3D
