A new method to convert unleveled marine seismic data to leveled split-spread data

During marine seismic data acquisition, the data are shot in the so-called end-on configuration, which means that the receivers are positioned only at one side from the source. In marine seismic data processing, the missing offsets at the other side from the source are often reconstructed by applying physical reciprocity, i.e., source- and...

Prestack time-time image map

In this paper we present a method for obtaining the pre-stack image map in the horizontal time – vertical time domain. Our approach is based on a data analysis in the double Radon domain, where the spatial complexity of the subsurface leads to a recognizable structure. Conventional velocity analysis is avoided by quantifying the scaling...
