Grid Modeling and Numerical Simulation of Multiphase Flow in Heterogeneous Reservoirs Using Orthogonal Collocation Schemes

Abstract

fax 01-972-952-9435. AbstractComplex features such as geological features (e.g. faults, pinch outs, inclined beddings); well related (multilateral wells of general orientation) can have significant impact on reservoir performance as well as reservoir fluid flow. These features are difficult to model using traditional finite difference methods, hence sophisticated gridding and discretization techniques are required if their effects are to be captured accurately in numerical reservoir flow simulators. Our model for reservoir stimulation uses advanced orthogonal collocation numerical simulators as well as grid transformation of the Cartesian coordinates(x, y, z) into curvilinear coordinates ( ) 42566 . 0 r = ξ using inference of the flow and pressure performance plots.
