Hydrofracturing is a water well method used to increase the yields of low-production wells. Some wells are drilled in bed rock where the fracture/joint systems are so poorly developed or so tight that little or no water can move through them. This is when the hydrofracturing method is used.

Hydrofracturing is done by setting a bore hole packer below the casing depth and expanding it. This isolates the production zone from the rest of the well. Water is then pumped at high-pressure and high-volume simultaneously through the water injection pipe. Because of the pressure and flow created, it will cause small, tight fractures to joints in the rock to open and the water to flow freely, connecting to the nearby water-bearing fractures and the bore hole. In the US, the success rate is generally acknowledged to be 95% of where the production of the well has been or at least doubled.
