Translation of "puits d'injection " (French → English) :

‘high-volume hydraulic fracturing’ means injecting 1 000 m3 or more of water per fracturing stage or 10 000 m3 or more of water during the entire fracturing process into a well;

Especially hydraulic fracturing, a process by which fracturing fluid – a mixture consisting typically of water, sand and chemical additives (generally between 0.5% and 2% of the total fracturing fluid)- is injected under high pressure to break the rock, open and enlarge fractures to enable the hydrocarbons to flow into the well, has raised a wide range of environmental concerns.
