Effect of the injection of a gas mixture (CO2 + O-2) onto residual hydrocarbons in a depleted oil reservoir: experiments and modelling

Abstract : CO2 geo-sequestration in hydrocarbon reservoirs is suggested as solution for limiting CO2 atmospheric accumulation. In the case of oxy-combustion CO2 capture, the main annex gas associated with CO2 is O-2 in important proportion. To predict the hydrocarbon evolution in the presence of O-2 in oil-depleted reservoir, it is essential to investigate their reactivity by a double approach combining experimentation and modelling. Experiments were carried out on a model compound (n-octane) and a detailed kinetic model for n-octane was applied. The consistency between experimentations and model is promising for the development of a tool allowing the prediction of hydrocarbon reservoir stability.
