Abstract

The disturbing influence of the weathered layer can deteriorate the result of all further data processing steps significantly. It is therefore important to remove these influences in the surface-related pre-processing step. Traditionally these corrections are valled 'static' corrections, because they generally consist of time shifts applied to the seismic data. In more advanced schemes weathered layer corrections are not restricted to time shifts only. Also amplitude decay and occasionally, when detailed information about the weathered layer is available, a wave equation based correction is carried out. In this paper we investigate to what extend the conventional static corrections are adequate and how an elastic wave equation baserf solution of the weathered layer should be implemented as part of a pre-processing scheme .
