KW - Reservoir modeling, grid generation, grid adaptation, global scale-up.
AB - <p style="text-align: justify;">Reservoir modeling is playing an increasingly important role in developing
and producing hydrocarbon reserves. In this paper, we provide a brief overview of
some main challenges in reservoir modeling, i.e., accurate and efficient modeling of
complex reservoir geometry and heterogeneous reservoir properties. We then present
modeling techniques we recently developed in addressing these challenges, including
a method for generating constrained Voronoi grids and a generic global scale-up
method. We focus on the Voronoi gridding method, which is based on a new constrained
Delaunay triangulation algorithm and a rigorous method of adapting Voronoi
grids to piecewise linear constraints. The global scale-up method based on generic
flows is briefly described. Numerical examples are provided to demonstrate the techniques
and the advantage of combining them in constructing accurate and efficient
reservoir models.</p>
