Abstract: Fire?flooding or in?situ combustion is an effective process for primary and secondary development of heavy oil reservoirs. Compared with water drive, this process is more complex, and few engineering methods can be used for studying production performance in fireflooding reservoirs. The paper proposes a new method to study fire?flooding reservoir’s productoin performance with gas?drive type curves,by which the problems in dynamic analysis during production can be well solved. This new method has been proved by production performance data obtained from Wellblock Hongqian?1 in Karamay oilfield and Suplacu oilfield in Rumania. Relations among cumulative oil production, cumulative gas production and produced GOR can be established on the basis of the gas?drive type curve. Finally, recoverable reserves by fire?flooding process can be determined with the relations as the fire?flooding reaches the economic limits
