... application to time-lapse elastic data is of considerable interest. For practical applications in reservoir monitoring, we need EFWI to provide high-resolution reservoir information at a reasonable cost. Thus, we develop an elastic redatuming technique to provide the required virtual elastic data for a target...

... frequencies of elastic data (vertical and horizontal components of particle velocity), respectively. Numerical example on the Marmousi2 model shows that the 2-4Hz low frequency data extrapolated from band-limited data above 4Hz provide good starting models for elastic FWI of P-wave and S-wave velocities...

..., the data predicted by the acoustic engine and the field data have different AVO effects, resulting in artifacts in acoustic FWI inversion results. In this study, we adopt a deep learning approach to transform the elastic data into the corresponding acoustic traces. We design a series of numerical tests...

... ABSTRACT We present new scalar wave-equations that can characterize P-, SV- and SH-wave in transversely isotropic (TI) media. They can be used as the basis for migration of both acoustic and elastic data. SH wave-equation is directly separated from the 2D VTI elastic wave-equation. P and SV...

In this paper we show how it is possible to make acoustic inversion work on elastic data. The experiment is carried out by using acoustic time...
