Enhanced Oil Recovery from Permian-Carboniferous Deposit of High-Viscosity Oil in the Usinsk Oilfield with Physicochemical and Complex Technologies

摘要

Presented are the results of field tests and commercial application of the physicochemical and complex technologies created by IPC SB RAS on the Permian-Carboniferous deposit of high-viscosity oil in the Usinsk oilfield. The technologies are intended to enhance oil recovery and for water shutoff using thermotropic gel-forming and oil-displacing systems under natural development practice and together with thermal-steam stimulation. Technological effectiveness and ecological safety of the technologies and their prospects for commercial application are shown.
