OSTI ID:153067
The reservoir modeling approach presented in this paper illustrates how available engineering tools can be used to evaluate the technical feasibility and economics of high-pressure gas injection. The key components to such a study included: (1) equation of state (EOS) modeling of experimental PVT data, matching miscible and immiscible slim tube results, and systematically reducing the number of components used in the EOS model to minimize computational requirements, (2) studying numerical grid effects, displacement mechanisms, optimal well pattern, and injection pressure with 2D cross-section and 3D sector models, and (3) comparing compositional results with simulations based on the black-oil PVT formulation used in full-field history matching and reservoir management modeling.
