Processing 3D seismic data recorded in complex surface seismogeological conditions by an irregular observation system

The article presents the sequence of processing seismic field data recorded by an irregular observation system in complex surface land and marine seismogeological conditions from various types of excitation sources and types of seismic receivers with a high level of man-made interference in the framework of the method of the middle depth point with a large overlap ratio in order to prepare them for time and depth migration according to seismograms. The article discusses in detail the stages of processing seismograms that make it possible to effectively suppress industrial and man-made interference arising during field work in industrial areas with a developed transport infrastructure. This ensures high reliability of the results after migration, which are necessary for the correct construction of a seismogeological model of the hydrocarbon deposit, the subsequent forecast of reservoir properties and a comprehensive assessment of the resource potential of the studied territory.
