Diffraction identification in data domain: influence on diffraction imaging

Scattered waves are used to construct diffraction seismic images. There are various algorithms for their extraction, which can be divided into three classes regarding the data processing steps: data domain procedures, migration-based methods, and image processing. The presented paper provides an investigation of the influence of the data domain extraction of scattered waves on the migration procedure based on the construction of selective images. Numerical experiments were performed using synthetic data got for a realistic model with fractures for the field in Eastern Siberia.
