OPTIMIZED WATER QUALITY INJECTION STRATEGY FOR RESERVOIR PRESSURE SUPPORT

摘要

A method for supporting the pressure of a subsea hydrocarbon reservoir, the method comprising: recovering produced fluid from a subsea hydrocarbon reservoir; separating produced water from the produced fluid; providing seawater; mixing the produced water and the seawater at a determined ratio in order to provide mixed water having a desired temperature; and injecting the mixed water into the subsea hydrocarbon reservoir.
