COMPARISON OF FINITE-DIFFERENCE SEISMOGRAMS AND RAY-THEORY TRAVEL TIMES IN THE ELASTIC SEG/EAGE SALT MODEL

摘要

Finite-difference seismograms for a selected shot and five receiver configurations computed in the elastic SEG/EAGE Salt Model during the Next-Generation Seismic Modelling and Imaging project are compared with ray-theory travel times. Two-point rays and travel times of direct, refracted and reflected P-waves and converted S-waves in the smoothed elastic SEG/EAGE Salt Model are computed.
