Oxygen fireflooding as a means of enhanced oil recovery is receiving increased evaluation in the laboratory and in pilot field tests. As in the case of air fireflooding, the combustion tube can play an important role in understanding some of the parameters of oxygen fireflooding for a variety of crude oils. A total of five light, medium, and heavy crude oils was evaluated in a combustion tube primarily at 750 and 2000 psig and with oxygen concentrations between 21% (air) and 95%. As was reported in a previous paper, which was concerned with a light oil only, the overall characteristics of the combustion with oxygen appear to be superior to the characteristics with air. For light and medium crude oils, when the combustion conditions are marginal (e.g., at low temperature for which the kinetics appear to control the coke combustion) the apparent kinetics and the quality of the combustion were substantially improved when oxygen enrichment was utilized.
