In addition to the spatial resolution, robustness to random noise is another important assessment criterion, for which we consider two distribution patterns (concentrated and scattered) of traces contaminated with strong random noise. We also evaluated their effectiveness to visualize...

... Seismic source localization plays an important role in (Schuster et al., 2004). However, as Schuster et al. (2004) estimating the hypocenter of earthquakes and in monitoring point out, the spatial resolution of the source image is poor hydraulic fracturing. Interferometric cross-correlation mainly due...

... ABSTRACT We propose a method to improve the spatial resolution of seismic reflection data by implementing shaping regularization with inversion to zero-offset. We apply finite-difference offset continuation iteratively in the log-stretch frequency-wavenumber domain within the shaping...

The spatial resolution of the acoustic P-wave image could further deteriorate in the presence of strong mode-converted shear waves and/or multiples in the data. The shear energy will give rise to the presence of cross-talk...

...); both effects were investigated individually on models of different spatial resolution. It was shown that temporal aliasing will cause underperformance in the reproduction of target properties when the spatial resolution is low, and will have minimal effects in areas of high spatial resolution...

However, there are two problems with LSM: the cost can be an order of magnitude more than standard migration and the quality of the LSM image is no better than the standard image...

For a strictly periodic fracture network (i.e., constant fracture spacing), the smallest spatial resolution that can be resolved is half of the wavelength. One can readily observe seismic wave scattering including multiple scattering...

The TSV encoding allows us to reduce the cost of imaging by at least an order of magnitude relative to conventional shot-record migration. Overall, we provide a framework for finding blended source encoding schemes, that produce...

... Summary The general spatial resolution is relevant to offset, so it should be taken into account in seismic survey design. In this paper we determine maximum offset by studying the decreasing rate of spatial resolution, and analyze some application effects. The principle by which we...
