Hydrofracturing Options

What Is Hydrofracturing?

Originally developed in the oil drilling industry, hydrofracking is the practice of pumping water into new or existing water veins to enhance water flow. This process increases water production in existing wells. Our success rate for achieving a higher GPM (gallon per minute) output is over 98%.

How Does Hydrofracturing Work?

  • The pump is removed from the well and the depth of the well is measured.
  • The well is then videoed to determine the depth of the casing and the presence of any large existing fractures that may damage the packers.
  • Our packers are lowered into the well. The packers are then inflated. The frac pump begins pumping water into the space between the packers, building pressure and fracturing the well. The packers are deflated, lifted 40′ and the process is repeated.

The single packer set is the most common method used. After a well has been drilled silt and deposits may start to build up in the water producing fractures causing a decrease in overall well yield.

A packer is lowered down the well to pre-determined depth (Usually 20' below the casing or a minimum of 60' whichever is deeper), and water is injected into the well at high rate of volume and pressure. This will remove the obstruction and open up the water producing fractures.

Now that the obstructions have been forced out of the water producing fractures, more water is able to flow into the well increasing the overall yield of the well.

"Zone" or straddle fracking is utilized. Two packers are lowered down the well isolateing a specific "zone" to be Hydro-Fracked.

Once that zone has been freed of its obstructions, the process is repeated at even intervals until the entire well has been Hydro-Fracked.

By concentrating the injection to where it is most needed, zone-fracturing insures optimum yield.
