2007e - Reconstrução Topológica Tridimensional de Objetos Geológicos em Bacias Marítimas Usando Dados Sísmicos 2D ou 3D: uma Ferramenta Exploratória e Explotatória de Hidrocarbonetos


Abstract:
The interplay between geophysics and geology is today one of the main challenges in reservoir characterization. In this paper we expose the ideia that by careful mathematical formulation and computer graphics tools it is possible to reconstruct 3D geological forms starting with seismic parameters. We reconstruct all the topological components of isosurfaces in subvoxel resolution starting with seismic parameters. Each isosurface component represents the boundary of a geobody. This type of reconstruction helps the modeler to understanding better the seismic information, the geobody spatial characteristics and make quantitative estimations such as reservoir volume.
