<p>The " METHOD OF DYNAMIC SEISMIC PROSPECTING ", is a technological innovation applied to Seismic Prospecting in oil and/or natural gas exploration, based on changes in the conception and treatment of the behavior of the reflections of the seismic or sonic waves in the geological layers of the subsoil, in accordance with Fresnel's theory, in order to improve the current methodology and overcome the problems and limitations thereof, The method includes two novel aspects :
The acquisition of field seismic data uses 2D and 3D seismic meshes and lines having a lower density of shot points and geophones, as a function of Fresnel diameters, resulting in substantial savings of time and cost in seismic exploration. When reprocessing seismic data, the seismic images or sections obtained through a conventional method are subjected to a process that corrects the deformations or distortions not resolved by current conventional methods. To that end, a geometric process is used that makes it possible to obtain an image closer to the true configuration of the geological structure being studied, avoiding errors in the location of geological faults, in drilling dry wells, or non-detected structures of lesser range, etc. and thus avoiding financial losses and losses from natural resources not being exploited owing to deposits being needlessly abandoned.</p> |
