Hydro-Fracturing for Low-Yield Wells:

Hydro-fracturing, or hydro-fracking, is a modern technique designed to enhance water production in low-yield wells. This process works by pumping highly pressurized water down the well to create small cracks and micro-fractures in the surrounding bedrock. This action not only creates new pathways but also clears existing ones, allowing groundwater to flow more freely into the well. This method is particularly effective for bedrock wells, where water is stored in natural fractures and fissures. By expanding these existing openings, hydro-fracking can often transform a dry or low-producing well into a reliable water source

Limitations and Best Practices

While highly effective, hydro-fracturing is not a universal solution and has specific requirements. The technique is only viable when a well is uncased through at least 200–300 feet of solid bedrock, providing sufficient rock for the process to be effective. To ensure safety and prevent damage, the pressurized water must be applied at least 50 feet below the well casing. This critical step helps prevent serious issues such as casing lifting, damage to the surface seal, or fractures extending to the surface. Overall, hydro-fracturing offers a controlled and efficient method for increasing groundwater flow, making it a valuable option for improving low-yield wells in bedrock-rich areas.
