Also known as water hydrofracking, this procedure uses high volume high pressure water to increase the well yield or gallons per minute (GPM) of a well. Hydrofracking water wells costs the same whether you are performing this on a brand new well or an existing one. The only difference is if a pump is in the well that would need to be first removed. Once the pump is removed the well is filled with water and an inflatable tool called a Packer is lowered down into the well on either steel or aluminum piping. The inflatable Packer is hollow in the middle, which allows water that is being pumped into the piping to go beneath the Packer, this is where the pressure is built inside the well. Most standard Packers are inflated to 1800 PSI and once inflated can withhold up to 3000 PSI of pressure beneath them.
The pressure is created by pumping high volumes of water typically at a rate of about 100 GPM down through the Packer into the borehole where the water pressure seeks out the weakest areas or fractures in the well. These areas are where the water is blocked or restricted and the water used in the hydrofracking process will erode away these fractured areas that carry the water to the well essentially making the fractures larger so they can carry more water to the well.
The procedure of hydrofracturing originated in the oil fields and was found to be so successful that the water well industry started to use the procedure. Many people ask “does hydrofacking water wells work”? This procedure was first introduced in the well industry over 30 years ago and is still widely used in the industry today. The success rate of hydrofacking water wells is remarkably high around 99% of wells that are hydrofractured do show an increase in the yield of water.
One of the benefits to hydrofrac a water well is the procedure only takes a few hours to complete and there is no digging necessary that would normally be associated with drilling a new well or deepening an existing one. The downtime is also considerably less with a hydrofracked well in most cases less than 24 hours.
Also, the cost of hydrofracking a well is much less then what it would cost to drill a new one or to deepen a well. Hydrofracturing water well costs do vary depending on the precise procedure that is being performed. For wells that need to produce a high volume of water such as an irrigation or commercial well then it would be recommended to zone hydrofracture those wells using two packers and the pressure is contained between the two packers. The packers are usually placed 50’ apart and the well contractor will start near the bottom of the well working up in 40’ increments there by pressurizing the entire borehole by the end of the process.
Well owners will often ask: “how many gallons per minute do I need for my house”. That is a loaded question since there are so many variables that go into water usage. For example, how many people live in the house, how many bathrooms are there in the home, is there an irrigation system. All of these factors come into play when determining the demand for the water well and if your well falls short of the demand than hydrofracturing your well, may be the solution you are looking for.
