3D-Parameterization of the 3D Geological Space – The GeoChron Model

A004 3D-PARAMETERIZATION OF THE 3D GEOLOGICAL SPACE – THE GEOCHRON MODEL Abstract 1 One of the key points in reservoir modeling is the building of a complex 3D-mesh which must integrate various constraints: respecting the geometry of the fault network taking into account stratigraphic knowledge computing petrophysical properties by geostatistical methods allowing upscaling and/or flow simulation… The building of this mesh relies on the use of a parametric coordinate system (u v t) such that (u v) corresponds to “horizontal” curvilinear coordinates tangent to the horizons while (t) corresponds to the “vertical” curvilinear axis approximately orthogonal to the horizons.
