... extent. We suggest a formation mechanism for the artifacts emergence by considering seismic migration as a superposition of subsurface offset extended impulse responses, contributed by individual data traces. The accumulation of the image, in a trace-by-trace manner, gives an insight to its fundamental...

..., the sum of these individual cubes is used which builds on the principle of superposition. If a feature is present in more than one direction, it will be further highlighted, and features such as noise, which are usually present only in a certain direction at time, are suppressed. The objective...

... independently, then each Gaussian packet is mapped into model domain and a perturbed model described with Gabor function ("Gaborperturbation" for short) is inversed. The superposition of all the inversed Gabor-perturbations produce the final inversed perturbed model. Numerical examples show that the proposed...

... of Gaussian beams (GB). In contrast to common approach to GB prestack migration (see, for example, (Hill, 2001)) we do not use superposition of GB in order to get the Green’s function. We shoot instead a couple of properly chosen GB with fixed dip and opening angles from the current imaging point towards...

... Summary In seismic reflection surveys, the superposition of P- and Swaves often influences the resolution of obtained images. We, therefore, needs to first decompose multi-component data before imaging procedure even in Fresnel volume migration. For decomposition processing of refracted Pand S...
