FROM AUTOPICKED HORIZONS TO 3D MODEL AND TO FAULTED STRATIGRAPHIC GRID

 abstract = { In [2], a general workflow, aimed at creating 3D models without computing intersections, is presented. This workflow has to be adapted according to the data that are available. In the following, the same workflow is presented in the particular case where only horizons are available. These horizons are autopicked from 3D seismic data and represented by sets of points. From these horizons, we want to create horizon and fault surfaces, define contacts between faults, horizons and boundary of the model, and finally create a 3D mode!. In this particular case, contacts are created first, then fault and horizon surfaces are created from these contacts. These contacts are defined from polygonal lines representing the internai and external borders of the faulted horizons. In the first step, horizon borders are extracted as a set of points; the second step is aimed at connecting these points in order to build polygonal lines. From these lines, we will then define the contacts between horizons, faults and boundaries. Only then, we will generate the corresponding triangulated surfaces in such a way that they geometrically respect the contacts that have been topologically defined. Finally, by creating triangulated surfaces that share the same mesh discretizations along the contacts, a volumic boundary representation model (see [9]) can be created without computing any intersections. The information that is extracted from the horizon borders is also used to set automatically links that are used for the creation of a faulted stratigraphie grid. },
