Orr, Jr, F M

This report describes a one-dimensional process simulator designed for carbon dioxide (CO/sub 2/) flooding applications, though much of the code is equally applicable to surfactant flooding simulations. The simulator, CO2FLD, follows convection of four components. Three components enter into phase equilibrium calculations for up to three phases containing hydrocarbons and CO/sub 2/. The fourth component is water which appears only in a separate phase. Material balance equations for the four components are solved by a fully explicit finite difference method which allows the use of numerical dispersion to simulate the effect of physical dispersion, which is not modeled explicitly. Section 2 of this report contains a description of the formulation of the model; section 3 summarizes the representations of phase behavior; and section 4 outlines fluid property and relative permeability models used in the simulator. Section 5 compares numerical solutions to analytic solutions for simple cases. Input data formats are described in Appendix A. The use of routines for automatic plotting of run results is detailed in Appendix B. Appendix C is a description of a simple least squares program for selecting parameters for representing a binodal curve based on experimental data. Appendix D contains listings of CO2FLD, associated plotting routines and the routine for determining binodal curve parameters in addition to a brief description of each subroutine in the various programs.
