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 perforated pipe section with a pair of inflatable packers. The tool is lowered into the borehole to the deepest interval to be fraced. The length of the tool is sufficient to span the width of the interval. The packers are then inflated thus sealing off the area in the borehole next to the interval. High-pressure water is then introduced through the drill stem and through ports in the perforated pipe section. After sufficient high-pressure water has fractured the surrounding interval, gravel proppants are forced into the surrounding fractured interval. Upon discontinuing the hydrofracturing of the interval, the two packers are deflated and the hydrofracture tool is moved upwardly to the next water-bearing interval and the process is repeated. After fracing the intervals, the well is now completed using normal well completion techniques.
