Application of Unconventional Techniques in Constructing an Integrated Reservoir Simulation Model for Troll Field

Abstract

A number of unconventional techniques were used for constructing an integrated three-dimensional (3D), three-phase numerical reservoir model of the huge Troll field. The selected techniques included comer-point geometry (CPG), non-neighbor connections between grid cells, local grid refinement, improved vertical equilibrium (VE) description, and oilwell coning functions. By combining these techniques, an efficient model, capable of handling several complex reservoir problems simultaneously, was developed. This model became a flexible tool Jor reservoir management planning.
