Abstract
Summary
We applied the time-domain pseudospectral method on the classic acoustic wave equation (with S-wave artefact) and the new acoustic wave equation (without S-wave artefact) for vertical transversely isotropic media. Both were employed to simulate the wavefield in simple and complex media. Reverse time migration (RTM) by the two equations were tested for the VTI Marmousi model. It is shown that both equations generate similar images in RTM but the new qP-wave equation is better regarding the computational performance.
