a well through which geothermal water is returned to an underground reservoir after use. Geothermal production and injection wells are constructed of pipes layered inside one another and cemented into the earth and to each other. This protects any shallow drinking water aquifers from mixing with deeper geothermal water.
A well in which a liquid is pumped down into the ground under pressure so that it passes from the well back into the pore space of the rock or regolith.
A well constructed for the purpose of injecting treated water, often wastewater, directly into the ground. Water is generally forced (pumped) into the well for dispersal or storage into a designated aquifer. Injection wells are generally drilled into aquifers that are not used as a drinking water source, unused aquifers, or below freshwater levels.
A well that is used to force a fluid into the ground. The injection could be done for disposal or to place the fluid (such as natural gas) into a subsurface reservoir.
a well through which fluids are injected into an underground stratum to increase reservoir pressure and to displace oil.
A well employed for the introduction into an underground stratum of water, gas or other fluid under pressure. Injection well are employed for the disposal of salt water produced with oil or other waste. They are also use for a variety of other purposes: 1) Pressure maintenance, to introduce a fluid into a producing formation to maintain underground pressures which would otherwise be reduced by virtue of the production or oil or gas, 2)Secondary recovery operations, to introduce a fluid to decrease the viscosity of oil, reduce its surface tension, lighted its specific gravity, and drive oil into producing wells, resulting in greater production of oil.
a well that injects a fluid for secondary or enhanced oil recovery, including reservoir pressure maintenance operations
A well used for the emplacement of fluids into a subsurface stratum. DWS Rule 1220-4-6-.02
Well used to inject fluids (usually water) into a subsurface formation by pressure.
A well used for injecting water or gas into a formation in a pressure-maintenance operation or in secondary recovery.
A well used for injecting fluids into a formation in an attempt to increase recovery efficiency.
A well used to inject gas or water into the reservoir in order to maintain reservoir pressure in secondary recovery projects or for conservation purposes.
A well used for pumping water or gas into the reservoir.
Any well used for the disposal of air, gas, water or other substance into any underground stratum.
refers to a well constructed for the purpose of injecting treated wastewater directly into the ground. Wastewater is generally forced (pumped) into the well for dispersal or storage into a designated aquifer. Injection wells are generally drilled into aquifers that don't deliver drinking water, unused aquifers, or below freshwater levels.
A well that injects wastewater fluids into underground formations. Florida has five classes of injection wells, which are used to dispose of treated municipal effluent, stormwater, and industrial and hazardous wastes.
a well placed in, or adjacent to, a contaminated area for the purpose of supplying treatment to the subsurface; well historically used for the subsurface disposal of waste
A well used for injecting fluids (air, steam, water, natural gas, gas liquids, surfactants, alkalines, polymers, etc.) into an underground formation for the purpose of increasing recovery efficiency.
A well into which fluids are injected for purposes such as waste disposal, improving the recovery of crude oil, or solution mining.
Well used for injecting water or other fluid into a ground-water aquifer. See also artificial recharge.
A well into which fluids have been pumped, and from which fluids have been injected into an underground stratum to increase or maintain reservoir pressure.
