Common Reflection Surface (CRS): Imaging and AVO Analysis

Abstract

In order to make a better subsurface image, many researchers try to conduct processing seismic data using the Common Reflection Surface (CRS) method. So far results have verified that the CRS method is able to increase significantly signal to noise ratio. As a result, a seismic image produced has a better quality structurally and stratigraphically compared with a conventional stack method. Our finding show same imaging results. However a lot of questions raised whether amplitudes produced by the CRS method are preserved or not. Using 2-D land seismic data, this paper show that amplitude trends resulted by the CRS method are almost similar to those of the conventional method. In addition, results of amplitudes versus offset (AVO) analysis show that amplitudes of the CRS method are slightly clearer than those of the conventional method. This result can be one of the evidence that CRS may be used to improve quality of the AVO response.
