Simulation of Interbedding Processes with Air Injection into Oil Deposits with Various Geological and Physical Characteristics

Thermohydrodynamic simulator STARS of software package CMG performed calculations of technological parameters of highly viscous oil deposits with various geological and physical characteristics by initiating interbedding combustion with air injection into the reservoir. Various geological and physical characteristics include the depth of deposits, initial reservoir pressure, initial reservoir temperature, and oil viscosity in the initial reservoir conditions. The results of calculations showed that changes in average temperature of the reservoir, as well as indicators of oil production depend on geological and physical characteristics of the oil deposit. In accordance with the results of calculations, depending on geological and physical characteristics of the reservoir and oil viscosity we established criteria to use electric heaters at the initiation of interbedding combustion.
