Different models were used to determine the possibility of in situ combustion applications for heavy crude oil fields in south-east Turkey. In the first approach a one-dimensional model was developed, in which the frontal advance concept is combined with mass and energy balance equations with certain boundary conditions, limitations and assumptions. The recovery histories of three oil fields were determined; the highest recovery was obtained in field 2 with dry combustion and in field 1 with wet combustion, depending on the reservoir characteristics. From the recoveries obtained the profitability of the in situ combustion applications was calculated. In the second approach, a computer program was developed to apply the oil-recovery-volume-burned correlation method to the same oil fields. The results showed that in situ combustion is applicable in these fields if the volume burned is 30% for fields 1 and 3 and 40% in field 2. To assess the feasibility of in situ combustion, the minimum oil content of the reservoir was determined for field 1 by thermal analysis.
