Hydrofracturing
Rehabilitation
Injecting high-pressure water into a low-yield well to open natural fractures and improve flow.
In hard-rock wells with disappointing yield, hydrofracturing forces water under thousands of psi into the borehole to widen existing fractures and connect new ones. It is a long-established water-well technique unrelated to oil-and-gas fracking and uses no chemicals — only water. Successful hydrofracs can double or triple yield in fractured granite and quartzite wells.
