What is hydrofracturing and when is it useful?

Hydrofracturing is a well development process that involves injecting water under high pressure into a bedrock formation via the well. This is intended to increase the size and extent of existing bedrock fractures, pumping water into those fractures at pressures as high as 3000 psi and flow rates as high as 85 gallons per minute, this cleans out the fractures and allows them to interconnect with nearby water bearing fractures. Water can then flow back thru these fractures and into the well at a faster rate than before.

This is useful when a bore has gone dry but the neighbouring area holds water. The bore must have reached the same depth or more than that of neighbouring wells with water yield.
