Practical Application of CRS Processing to Improve the Imaging of The Geological Environment

Low initial traceability of reflected waves on 2D/3D CDP seismic data is the reason for obtaining conflicting geological models, which leads to problems when drilling wells, which is unacceptable in the current economic situation. The main factors influencing the traceability of reflected waves can be identified: the complex geological structure of the environment, technical and human factors, the complex geological structure of the upper part of the section. The use of standard seismic data processing techniques cannot fundamentally solve these problems. One solution relates to the use of CRS (Common Reflection Surface) technology. The method of the common reflecting surface, which allows, based on the attributes of the wave field, not only to improve the detail and increase the signal-to-noise ratio, but also to carry out regularization in different sortings, taking into account the velocity characteristics of the imaging.
