An implicit numerical method is presented for simulating the differential and algebraic relations governing one dimensional, three-phase flow in porous media. The method is based upon compositional representation of the hydrocarbon system. Variable physical properties and water oil capillary forces are included in the formulation; however, in the model described the effect of gravity is ignored. The effects of changing composition and mass transfer are considered through the use of known phase behaviour concepts and correlations.
Presented are the results of using this method on a single-phase, two-hydrocarbon-component gas displacement laboratory experiment. To further examine the validity of the formulation, the method is also applied in simulating both a solution gas drive and a gas injection problem using a reservoir oil represented as a nine-component mixture. These latter two problems are examined in comparison with a simulation using a one-dimensional volumetric model.
The results of these studies demonstrate not only the validity and relevance of this method, but also the necessity of this approach in application to the general reservoir engineering problem.
