General Information About Injection Wells | US EPA
2024年7月10日 · Definition of injection well. An injection well is used to place fluid underground into porous geologic formations. These underground formations may range from deep sandstone or limestone, to a shallow soil layer. Injected fluids may include water, wastewater, brine (salt water), or water mixed with chemicals.
Injection well - Wikipedia
Injection wells can insert clean water into an aquifer, thereby changing the direction and speed of groundwater flow, perhaps towards extraction wells downgradient, which could then more speedily and efficiently remove the contaminated groundwater.
Water injection (oil production) - Wikipedia
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.
injection wells which can penetrate thousands of feet below the earth’s surface, See Figure 5. But what is underground injection and how is it regulated by the UIC program5? Underground injection is the placement of fluids into the subsurface through a properly constructed well.
What are underground injection wells used for?
Underground injection wells, where water and/or other substances are injected into the Earth, are used for a wide variety of purposes. The U.S. Environmental Protection Agency (EPA) regulates around 850,000 underground injection wells through its Underground Injection Control program under the Safe Drinking Water Act.

Water Injection - MOGAS
Water injection is used in the production of oil where high pressure water is injected into the oil reservoir to increase pressure to increase oil recovery from an existing reservoir. Water injection wells can be found both on- and offshore. The injected water pressurizes the reservoir and displaces the oil, pushing it towards a well.
