The hydro-fracking process involves injecting high pressure water into the formation to increase the size and extent of existing fractures and to create new fractures. Hence the formation permeability and well yield are increased.
The components used for this technique are:
- Our specialized truck with a crane to lower and raise the packers
- A source of clean water
- A system of pumps adequate enough to handle the volume of pressure needed, which can pump at an adequate rate
- Assorted valves, gauges and fittings for controlling fluid injection delivery
- Two inflatable packers with high pressure tubing and a supply unit for inflation
The pump system is removed from the well, and the packer system is then set up and lowered into the well to a pre-determined zone area. In the first zone both packers are inflated. The area where the water is injected is 230 feet down to the bottom of the well. The pressure is then released. In the second zone a valve is shifted down in the bottom packer, preventing the water from going out of the bottom. The water will go out of the formation from a depth of 208 to 225 feet. After pumping a specific amount at this depth, the pressure will then be released. The assembly is then lifted to the depth of 191 to 208 feet and the process is repeated. The packer system is then raised and the process is repeated. The packer system is raised 17 feet each zone, for a total of eight zones or more.
Starting from the bottom and raising the system as the zones are pressurized minimizes the risk of large rock pieces, possibly broken off during the injection process, interfering with packer setting and removal. The well is then tested to determine the increase in well yield.
We must all understand that groundwater is a natural resource, and there is no way of knowing how much of an increase can be expected. There are so many different formations in the earth, which cannot be seen by anyone. The average household of four people uses an average of 70 gallons per person, per day, for a total of 300 gallons per day.
