In the present there is an active offshore oil& gas shelf fields development. The standard methods applied for investigation of near surface geological conditions for site survey goals are high resolution seismic (HRS) for top hole drilling hazard assessment and ultrahigh resolution seismic (UHRS) mutually used with hydrographic surveying for sub-bottom geohazard assessment. On the other hand, application of 3D seismic technology for site survey investigations requires improvements both in data processing and interpretation. This paper focuses on the generalization of experience in the geohazards assessment in offshore fields based on the 3D seismic data.
