WebFigure 4 The 2004 BP velocity benchmark model. The yellow curve defines the base of the top region and the green curve defines the base of the middle region Figure 5a shows an RTM image in the left side of the BP model, and 5b shows a composite image obtained by using one-way WEM for the top and bottom regions and RTM for the middle region. WebThe result is a computationally efficient and accurate implementation. We show the potential of the method by using the BP 2004 velocity benchmark model. There, our regularization scheme allows the inversion to start from a simple velocity model and delivers a high-quality reconstruction of salt bodies.

Numerical Examples: The 2004 BP Velocity-Analysis …

WebExperiments on 1D velocity models, the Marmousi model, and the 2004 BP model determine that NNFWI can mitigate local minima, especially for imaging high-contrast features such as salt bodies, and it significantly improves the inversion in the presence of noise. WebWith these two adaptations, our Laplace-domain waveform inversion could then be tested on a very large 2004 BP velocity-analysis benchmark data set. Numerical tests of the BP model, which contains three salt domes of high-velocity contrast, were conducted on a self-made synthetic data set by Laplace-domain modelling and a time-domain original data set. dublins nickname

"WebThe merit of the proposed method is that it not only compensates for the amplitude loss and phase change, which cannot be achieved by traditional RTM and LSRTM of multiples, but it also provides more information about the subsurface with fewer crosstalk artifacts by using multiples compared with the viscoacoustic LSRTM of primaries.

WebThe approach relies on deterministic operators that capture the dip-dependent amplitude and phase anelastic effects seen by the waves as they propagate through a 3D anelastic medium, and corrects for them by inversion in the image domain. It provides fully deconvolved images (reflectivity) compensated for both anelastic and illumination effects. WebThe importance of reliable source wavelet information during the waveform inversion implementation has been widely implied or briefly mentioned by multiple authors, but little detailed study of the effects of poor wavelets has been presented in the literature.
