Substantiation of thermal effects on carbonate formations with high-viscosity oil of Northern Iraq Qaiyarah oilfield

摘要

The prospects for enhanced oil recovery on carbonate reservoirs with high-viscosity oil of Qaiyarah oilfield by thermal treatment technologies are considered. The existing technologies of thermal treatment are reviewed. Covered the advantages of combined stimulation with reference to the geological production conditions of development of carbonate beds Euphrates and Jeribe. Presents the results of predicting the process of oil recovery from carbonate reservoirs by pulse-dose of heat and cyclical in-situ polymer-thermal effects.
