Water Injection

The Water Injection technique used in oil production is where water is injected back into the reservoir generally to increase pressure and thereby stimulate production. Water injection wells are naturally found offshore. This method is used to enlarge oil recovery from an existing reservoir- Water is injected to force unrecovered oil out of tank rock and into nearby oil wells. Usually only 30% of the oil in a reservoir can be extracted. With Water Injection that percentage will be higher and the production rate of a reservoir is secure over a long period of time.
