This concept paper explores the potential applications of air injection (in situ combustion) as a follow-up to cold production of heavy oils. Cold-produced fields are ideal potential candidates for air injection due to the significant resource that remains. at the economic limit of cold production, and because wormhole-type channels are present in the depleted reservoir. The authors propose steaming the depleted reservoir for a short period of time to collapse the wormholes, thus creating high permeability heated channels. Reservoir ignition and air injection would follow, with the heated channels providing a now path for the mobilized oil to reach the production wells. The steam/combustion combination would be highly effective in thin reservoirs, where extended steam injection is uneconomic. Additionally, this process addresses the three technical causes for failure in heavy combustion projects: ineffective ignition, inadequate air injection rates, and temporary plugging of the formation due to blockages caused by high liquid saturations. An overview of cold heavy oil production and heavy oil by in situ combustion is provided, as well as a detailed discussion of the proposed process.
