A set of quadruply coupled equations (fluid flow, convection-diffusion, energy conservation and mechanical equilibrium) with a number of cross-couplings and coupled constitutive relations is formulated to quantify the multi-physics of oil displacement by CO2 injection, implemented into and solved by using FEMLAB. FEMLAB is the first engineering tool that performs equation-based multi-physics modeling in an interactive environment. With FEMLAB, the coupled multi-physics model can be solved simultaneously. The applicability of this model has been demonstrated through an example of simulations for a two-dimensional reservoir of size 1000 m×1000 m with one injection and one production wells. Model results illustrate the significant importance of the cross-couplings between individual (thermal, hydrological, chemical and mechanical) physics.

The traditional DEA model can not beused to deal with such stagewise operation problems. In order to avoid the limitation of the traditional DEA model, a multi-stage DEA model was set up based onthe idea of the DEA model with uncontrollable factor. Simultaneously, considering the shortage of the single DEA model, the multi-stage DEA model was extended to be the multi-objective one.
