... are consistent in the calculation, which is not consistent with the case of depth domain time-lapse earthquakes. The time-lapse seismic joint inversion avoids this assumption and is therefore more suitable for depth domain time-lapse seismic inversion algorithm. Method Depth domain wavelet calculation. We...

... Estimation of shear wave velocity is a method to obtain shear wave velocity from P-wave velocity and physical parameters, such as porosity, water saturation and clay content. The accuracy of estimated shear wave velocity depends largely on the inversion algorithm. We proposed an adaptive step...

The reason for this is that the small scale inhomogeneity within the Earth’s crystalline crust is complex and hence may be best described through stochastic rather than deterministic approaches. Thus, a 2-D random medium inversion algorithm using Fuzzy C-means (FCM) clustering...
