Hydro Frac (Hydraulic
Fracturing) is a process by which water is injected under extreme
pressure into the well to improve it's production capabilities. First
developed in the oil fields, the process was primarily designed to
increase oil production. The process has been modified to accommodate
the domestic water well need. The process begins by inserting an
inflatable "packer" which is similar to a giant balloon, down
into the well. At the point, the water is forced in under extreme
pressure (2500 PSI). into the cavity of the well, cleaning out the
fractures and allowing the water in the perimeter to flow freely into
the well. The success rate using this technique is very high, often
transforming a nearly dry well into a usable one.

THE HYDRO-FRACŪ
PROCESS
|
|
|
There are two ways to perform the Hydro-FracŪ process.
The single packer set and the straddle or "Zone"
setup. Below is a brief description of both. |
|
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,
zone-fracturing insures optimum yield
