Three-dimensional engineering seismic exploration for shallow waters

Efficient seismic exploration using SplitMultiSeis 3D technology

3D seismic exploration has a number of advantages over 2D profiling:

High level of research detail. Obtaining complete information about the structure of the studied thickness according to a continuous plan grid of bins.
3D seismic exploration allows you to obtain continuous fields of estimates of the properties of the studied geological media.
The possibility of 3D migration allows you to get rid of the effect of "lateral reflections" and leads to a significant (2 or more times) improvement in interference suppression compared to 2D profiling (with equal multiplicity).
High accuracy in the definition, delineation and analysis of geological hazards.
The possibility of studying the anisotropic properties of the medium.
