Abstract

Summary

In the last period there seems to be considerable interest in the production of 3D surveys in areas of Eastern Siberia. In the process of designing the field work, as a rule, the study of the upper part of the cut is not given due attention. When processing seismic data in areas with highly variable terrain of the observation surface is used not flat, but “floating” level of reduction. The effect of non-horizontal boundaries based on the OGT seismogram leads to overestimated velocity estimates. For the correct analysis of summation rates, it is proposed to calculate and use the local statics for the floating level of processing on each base of the OGT
