Results on the Sigsbee synthetic model show that the inversion regularized in the reflection angle reduces the effect of the uneven illumination not only in the angle gathers but also in the stack image.ValencianoValenciano, A.

Full waveform inversion of time-lapse seismic data can be used as a means of estimating the reservoir changes due to the production.Since the repeated computa-tions for the monitor surveys lead to a large computational cost,time-lapse full wave-form inversion is still considered to be a ...
In particular, an empirical, linear rock-physics model, properly calibrated for the investigated area, is used to rewrite the P-wave reflectivity equation as a function of the petrophysical contrasts instead of the elastic constants. This reformulation allows for a direct and a simultaneous ...
