Abstract

Separating upgoing and DOWNGOING WAVES is so important in the VSP interpretation. In this paper, visualization of eigenimage from SVD is used for separating upgoing and DOWNGOING WAVES. The results of SVD method on synthetic data are then compared with f-k method. For this purpose, using 2-D Fourier transform requires uniform sampling in both time and space.In applying median filter for separating upgoing and DOWNGOING WAVES, one of the events must become aligned carefully. According to the obtained results from implementation of SVD method on synthetic data, we can express that because of unneccessity to both uniform sampling and exact alignment, SVD method is prefered. Also, according to theoretical foundations of eigneimages, automatic noise attenuation through the proccessing is another adventage of SVD method.
