Water injection (oil production)

OverviewSources of injection waterFiltersDe-oxygenationWater injection pumpsWater injection plantsSources and notes

In the oil industry, waterflooding or water injection is where water is injected into the oil reservoir, to maintain the pressure (also known as voidage replacement), or to drive oil towards the wells, and thereby increase production. Water injection wells may be located on- and offshore, to increase oil recovery from an existing reservoir. Normally only 30% of the oil in a reservoir can be extracted, but water injection increases the re
