Modeling Chanel Forms Using a Boundary Representation Based on Non-uniform Rational B-Splines

Abstract

In many applications (e.g. object-based simulation), parametric forms are necessary to model geological bodies. In this paper, Non-uniform Rational Basis Splines (NURBS) are used to construct parametric channel forms. The models of geobodies are generated using a small number of parameters, and hence can be easily modified. This can be done by a point and click user interactions for manual editing or by a Monte-Carlo sampling onto parameter statistical distributions for stochastic simulation applications. These channel objects may also serve as support for defining facies regions in a classical reservoir 3D grid and thus for conditioning petrophysical modeling.
