Abstract
The paper describes the problem of distortion of stacking velocities estimated from CDP gathers caused by statics applied for compensation of the effect of near-surface (NSS) velocity anomalies. An analytical solution of the problem of stacking velocities correction for statics applied for NSS and deep velocity anomalies is presented. The results of numerical modeling demonstrate the high performance of the proposed solution. A comparative assessment of the accuracy of structural imaging with the proposed methodology and the option without velocity correction and other algorithms for solving the problem is provided.
