Preprocessing of Seismic Raw Data by Ray Tracing Method

Synthetic database for S-wave diffraction angle with source at different depth does not exist. Objective is to develop a synthetic velocity model for generating synthetic reflection and refraction data in standard Society of Exploration Geoscientist-Y (SEG-Y) format database. Velocity seismic profile database consisting of diffraction at the fractures and ray fan size are simulated. Nine layers velocity model is built by using finite difference method thus producing seismic wave propagation together with seismic ray tracing. Seismic ray tracing creates numerous number of rayfans. The angle of the reflection and refraction are calculated and tabled.
