Abstract
Improving the efficiency of exploration remains a priority issue for geologists and geophysicists. Detection and mapping of local small hydrocarbons deposits, likely associated with unconventional reservoirs, requires the use of non-traditional methods, one of which is multicomponent seismic survey. This allows obtaining all the necessary information: velocities of differently polarized elastic waves & their ratio, and, accordingly, Poisson’s coefficient. This fact improves the quality of seismic sections and gives them real geological (lithological) content, supplementing constructed models with information on reservoir properties and type of saturation. in this article we provide an overview of application results of using different variations of the multi-wave seismic in the context of solving various issues: identifying local oil-bearing zones, detailed mapping of the top part of the section and the permafrost, etc. According to the last researches, the introduction of this technology will optimize the exploration & exploitation of hard-to-recover reserves concentrated in non-traditional reservoirs, where multi-wave surveys still have great economic potential. Generally, based on a review of recent practical results provided by the multicomponent seismic, it can be concluded that the technology allows to expanding the range of issues, especially related to the refinement of difficult geological sections.
