Abstract
The paper contains studies performed for the purpose of determination of combustion front creation conditions near injection well following air injection into oil reservoir. The plotted line separating spontaneous combustion zone and zone free of spontaneous combustion following air injection is presented with corresponding differential values between air injection pressure and initial formation pressure that can lead to creation of combustion front near injection well following air injection into oil reservoir. Using Brea-Olinda oil field as an example via calculation it is possible to demonstrate relationship between time of combustion front creation near injection well following air injection into oil reservoir and injection pressure values on digital fluid flow model. It was noted, that during air injection having lower injection pressure values, combustion front creation time increases, and in case of increased overbalance, combustion front creation time decreases.
