What is the the Quality of injection water(oil well)?

I don't know where PD go his information but most of it is incorrect. Only at off shore locations might sea water be used for water injection. Other locations can use a variety of different water sources along as they are free of particulates, chemicals that might react with the reservoir water and 02.





Gas is very seldom injected into an existing oil field for the same purpose as water. Currently a great deal of CO2 is injected in various oil fields as a method of increasing the amount of oil produced. The CO2 acts like a dry cleaning agent to clean as much of the oil as possible that might be still ';wetting'; the surface of the reservoir rock.





It is not economical to transport by products from refineries to oil fields for injection. Typically the only refinery gases that are flared are those that must be released due to an equipment failure or other emergency.What is the the Quality of injection water(oil well)?

Filtered Sea water (avoiding shells etc) after de-oxygenation (avoiding bacteria growth)is normally used to inject the reservoir void.


Now a days gas is also used (the by produced gases while refining etc, which is not useful for industry, those normally releases through flare(flare is intended to burns out these by products)by this tech. pollutions is also reduced to great extent
