Development of podveryusky oilfield by the method of direct air injection into petroleum reservoirs on the ground of numerical modeling
Geologic structure features of Podveryusky oil field are considered in the article. Geologic modeling was carried out to specify producing reservoirs bedding according to the region’s fault tectonics, seismic investigations and geologic and physical properties of producing reservoirs. Thermal hydrodynamic models were created on the ground of a geologic model. They allow conducting investigations of alternative methods application with using oxidant injection in the layer and organization of complex areal development system. Application of in-situ combustion technology and thermal gas treatment is considered in the article as well. There are presented technologic data obtained during application of different development systems to choose the most optimal variant that leads to the highest oil recovery factor. Technologies of in-situ combustion and selective water flooding in deep-seated deposits are compared. Application of thermal gas treatment or in-situ combustion technologies could be a good alternative for oil fields which are located in harsh weather conditions far away from infrastructure because of economic attractiveness increase that is due to expenditure decreasing of pipeline systems development.
