Water quality for secondary oil recovery

The use of any source of water for subsurface injection without proper analysis and treatment could be disastrous to the whole system. Subsurface injection entails the injection of water into an oil reservoir to recovery some appreciable quantity of oil left behind after the natural energy might have died down. The water meant for the injection should be properly treated and cleaned otherwise the aim of the project would be defected. Discussed in this write up are the processes involved in the treatment of water meant for subsurface injection. The processes which are oil removal, solid contents removal, dissolve gases and oxygen removal must be properly carried out as outlined in this work to ensure a hitch free oil recovery operation. Proper adherence to the processes would ensure quality water that would meet the standard of the regulatory bodies.
