Title

APPLICATION OF SHAPING FILTERS TO ADJUST WAVELETS OF VIBROSEIS AND IMPULSIVE SOURCES

Pages

  31-40

Abstract

 Vibroseis is the cheapest and the most convenient source of energy for seismic data acquisition. Unfortunately, in certain areas continuous seismic date acquisition with VIBROSEIS is not possible (due to the varying terrain conditions, jungles woods and swamp or others environmental problems). Impulsive sources, alternatively, can be used to maintain continuous subsurface coverage and to keep the fold at the desired level. Different seismic sources usually generate different seismic wavelets. VIBROSEIS source produces a two-sided signal after correlation, whereas an impulsive source results in a onesided (causal) signal. During interpretation, if the above mentioned differences, the would mat be taken into account resulting seismic sections could possibly reveal false facies changes. In this study we showed that how one could solve this problem by applying two-sided recursive (TSR) shaping filters. We employed a deterministic, non-trace adaptive procedure considering the known parts of the seismic signal. The proposed strategy contains a minimum-phase conversion of both the VIBROSEIS and impulsive seismic data. It followed by a deconvolution and subsequent bandwidth limitation in the frequency range of data using a zero-phase band pass filter.
