Abstract

The paper summarizes results of reservoir modeling studies aimed to determine optimal geological and reservoir conditions for creating a stable burning front in heavy and extra-heavy oil accumulations developed by in-situ combustion (ISC) process. Reservoir depths and oil viscosities are the main factors that control the ISC process. The relationship between the oil viscosity and the reservoir depth corresponding to the conditions of creating a high-temperature combustion zone in the vicinity of the injection well simultaneously with air injection into the reservoir has been obtained.

Key words:

heavy oil accumulation, extra-heavy oil accumulation, in-situ combustion, reservoir flow model, reservoir depth, original oil viscosity, air injection, in-situ combustion front
