Abstract
The article considers the problem of distortion of effective velocities estimated from common depth point (CDP) gathers caused by implementation of static corrections for compensation of the influence of near surface velocity anomalies. An analytical solution of the problem of compensation of effective velocities caused by the static correction for shallow and deep velocity anomalies correction is presented. The results of numerical modeling demonstrate the efficiency of the obtained solution. A comparative assessment of the accuracy of time to depth conversion with proposed methodology, without velocity correction and other algorithms for solving the problem is provided
