... inversion plays an important role in exploration geophysics in dealing with the remanent magnetization issue due to their weak dependence upon the magnetization direction. We have adopted the amplitude inversion technique in Cartesian coordinates (e.g., Shearer, 2005; Li et al., 2010; Li and Li, 2014...

Two isotropic amplitude inversions using fast and slow convertedwave data successfully imaged the producing fluvial sand bodies in the Rulison Field and localized in time the intervals responsible for shear-wave splitting.

... is much less affected by gas (Berg et al., 1994). However, shear wave data is often not available, such as in this West Africa field. To correct for the amplitude loss due to shallow gas attenuation, we applied a turning ray amplitude inversion technique (Deal et al., 2002) to the prestack data before pre...

... Summary Turning ray amplitude inversion is a deterministic seismic processing algorithm that uses first-arrival data to generate a near-surface attenuation model that is used to compensate prestack or poststack reflection data for amplitude loss caused by shallow gas zones. Quantitative...
