Abstract

Example of the Bashkir-Serpukhovskaya deposit oil field in the Perm region where experimental studies were carried out and proved produced water and oil compatibility. Studies of porosity and reservoir properties (PRP) of cores showed their decrease when using fresh water from surface water sources to maintain the reservoir pressure (RPM), and to preserve RP when using produced water. Results of hydrodynamic modeling over a period of 20 years show benefits of using produced water for RPM, including oil production increase by 8% and saving fresh water from surface water sources in the amount of 12 million m3.
