Abstract

Gas injection enhanced oil recovery has long been used in petroleum industry to increase oil recovery factor. Carbon dioxide, nitrogen, flue gas and lean hydrocarbon gases were all being utilized as displacing agents. The oil swelling is an indicator of amount of gas dissolved into oil phase. Swelled oil has lower viscosity and flows more easily, then it improves recovery factor. In current study, a crude oil sample was used for experimental investigation. Solubility of methane gas in oil and swelling factor of the oil were measured by a Pressure-Volume-Temperature apparatus and High-Pressure-Cell equipment, respectively. Furthermore, reservoir simulation software, CMG-WINPROP, was used to estimate the PVT properties of gas-oil mixture and compare it with experimental data. It was used to calculate gas solubility and oil swelling factor, and also tune the equation of state with experimental data. Experimental result shows that the solubility of methane in oil phase and swelling factor of oil increase proportionally with pressure. Moreover, reservoir fluid phase behavior was predicted using a tuned equation of state against experimental data.
