Hydro-Fracturing (Hydro-Frac, Fracing, or Hydraulic Fracturing) is a technique used to stimulate the water recover rate in a low recovery water well. In some cases, your water production can be stimulated up to 20 times the previous rate.
Low recovery wells production can be enhanced by:
- Installing water storage systems
- Deepening the existing well to produce more storage in the bore hole
- Replacing or augmenting the existing well at another location
- Performing a hydro-fracturing operation
Determining which one is best for you is a subject you should discuss with our water well experts.
Hydro-fracturing is one of the most common techniques requested and has the highest potential for well improvement. Below is a discussion of this process and the results you may obtain.
How Is Fracturing Done?
A "packer is inflated against the well bore hole wall at 3,000 lbs. of pressure. This creates a seal in the well. Then fresh chlorinated water is pumped down inside the packer to the bore hole below. The pressure is increased until the rock formation begins to break down and fracture. We know this has happened when it begins to accept the injected water and the water pressure begins to drop. Next a mixture of sand and water is pumped into the newly formed fractures, and the old expanded and rejuvenated fractures. This helps scour the fractures and props them open while continuing to allow a porous surface for the water to pass through.
The placement of the packer starts at the top of the bore hole because rock fractures first at the shallowest depths. Additional packer settings are then made at 100 to 200 foot intervals down the well bore, depending on the well depth. Several thousand gallons of water are used in this process to insure that every possible fracture has been rejuvenated and created. A well test always follows the hydraulic fracturing process. However, several days need to pass before the test so we can determine the true amount of improvement that has been made.
Living Water has improved 90% of the wells that we have hydro-fractured. In one recent case, Living water improved the recovery rate from 1/2 gallon per minute to 11 gallons per minute.
How Long Will It Last?
The length of improvement depends on the type of rock the well bore was drilled into and other factors. Most mountain wells last 20 years or so before they need to be rejuvenated. Others last forever. Yet others need work every 3 to 5 years. Our experts can help you know how your well will behave and the the expected life of the well drilled and rejuvenated.
