Linear Noise Elimination by Hybrid Modeling on the Basis of Examples from Poland

Abstract

This paper deals with advanced non standard methods of land noise elimination with use of hybrid modeling and adaptive subtraction. Attached examples come from Poland from region near tide and shale gas areas. In seismic data processing production, dedicated approach is applied which allow to use interactive complex procedures leading to removal of random or coherent noise. Advanced hybrid models are presented where models of noise are iteratively and interactively created. Adaptive procedures allow to subtract modeled noise from seismic data. These operations allow to get proper quality of reflections and seismic image. Moreover, important issue is preserving amplitudes relations in this case. Important role play amplitude scaling for noise elimination and noise models creation. Discussed are interactive procedures and non standard approach to land noise elimination where moveout corrections and non surface consistent static corrections are also used to model. Noise removal, such as presented in this paper, is of great importance when high resolution of seismic image is needed.
