Abstract
Because of technological complexity and financial requirements to initiate a gas flooding project, a thorough evaluation before it is performed would be necessary. In this paper reservoir modeling approach was used to evaluate different flooding processes (miscible and immiscible) in a fractured oil reservoir. This study included: 1) equation of state (EOS) modeling of experimental PVT data, 2) determining MMP for different gas compositions using an slimtube model and studying the effect of grid number on results (numerical dispersion), 3) studying the effect of completion pattern and injection rate on recovery performance, and 4) comparing recovery performance in different flooding scenarios(CO2, N2, methane, enriched methane and water injection)
