ABSTRACT:
A process for hydrofracturing a specific interval or zone in a water aquifer from a water well borehole and introducing high-pressure water and gravel proppants for increasing water flow production from the water well. The process uses a hydrofracture tool having a pipe section with a pair of inflatable packers. The tool is lowered into the borehole to the deepest interval to be fraced. The packers are then inflated thus sealing off the area in the borehole above the interval. High-pressure water is then introduced through the drill stem and out a high-pressure injection port in the lower end of the pipe section. After sufficient high-pressure water has fractured the surrounding interval, gravel proppants are forced into the surrounding fractured interval.
