Well injection means the subsurface emplacement of "fluids" through a bored, drilled, or driven "well" or through a dug well, where the depth of the dug well is greater than the largest surface dimension.

Examples of Well injection in a sentence

  • Well injection may commence only after all well construction and pre-injection requirements have been met and a written authorization to commence injection has been obtained from the Director.

  • Well injection costs incurred to stimulate depleted wells are charged as an expense when incurred.

  • Hydraulic Fracturing: Well injection of hydraulic fracturing fluidMonitoring requirements and interaction of fracturing fluid with formation also occur in conventional wells but more extensive in high volume fracturing due to longer well length in contact with formation (up to 2,000 metres for high volume hydraulic fracturing compared to up to a few hundred metres for conventional well depending on formation thickness).

  • Well injection rates are expected to range from approximately 100 to 450 gallons per minute (“gpm”), with a minimum operating flow of approximately 50 gpm.

  • Well injection or infiltration of a substance or remedial material that would be considered a contaminant if otherwise detected in a groundwater or surface water resource constitutes a “discharge” and requires that a WPDES permit be issued.
