SplitMultiSeis 3D
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.
