The single packer set is the most common method used. It is designed to be used in circumstances where a minimal improvement is needed. 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.

Straddle Packer Setup

    When maximum yield is needed, "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, using zone-fracturing insures optimum yield
