Abstract

In recent years the number of 3D multi-survey seismic processing projects has been noticeably increased. This paper discusses some practical aspects of merging 3D land multi-vintages seismics undertaken during the seismic re-processing program in the Northern part of Pre-Caspian depression. The re-processing program comprises of seismic data pre-processing (including pre-stack data merge) followed by Time and Depth pre-stack migrations of four seismic vintages acquired over this area during the period from 1998 to 2006. Since all four surveys have different acquisition parameters the most challengeable issues of merging were related to the different survey’s orientation, different offset/azimuth distribution, significant variations in CDP coverage and CDP bin size.
