Injection wells are structures used to place fluids underground into porous rock formations. These wells are commonly employed for various purposes, including the disposal of wastewater, the storage of natural gas, and the enhancement of oil recovery. By injecting fluids deep into the ground, injection wells help manage waste and can improve resource extraction. The fluids injected into these wells can include treated wastewater, brine, or other substances. Proper management and monitoring of injection wells are essential to prevent contamination of groundwater and ensure environmental safety. Regulatory agencies oversee their operation to protect public health and the environment.
