Hydraulic Fracturing 101
If you say hydraulic fracturing, you are referring to a process of removing resources found underground such as geothermal energy, water, oil, and natural gas. The gas and oil industries make sure to use to their advantage the process of hydraulic fracturing. With the use of this process, the subsurface that you see in the fracture system will be enhanced. This will then lead to the natural gas and oil that you see from the pores of the rocks to move easily to the production wells. These wells will then be capable of bringing towards the surface the oil and gas.
Hydraulic fracturing usually begins the moment the wells or other infrastructures have been made. Drilling of production wells can be done in vertical sections or in directional or horizontal sections. Most of the time, the assembled well sections will then be drilled beneath the surface of the earth about thousands of feet away. From the production well, the horizontal sections could move away between 1000 to 6000 inches.
During the hydraulic fracturing process, high pressure is used to push the fluids to the geological structure. Such fluids are composed of water and chemical additives. Usually, this process can only become a success if the amount of fluids that will be pushed through are thousands of gallons. With the help of the high pressure that is applied, the rock fractures will then become weaker as they can while they will also become bigger with the help of the chemical fluids pushed towards them. This can be done at very long distances some even reaching several thousands of feet.
The faults will be have a propping chemical pushed to it when the process has already reached the desired fracture that they need. Doing this is crucial to process to keep the faults opened once the fluids must be pumped. After the hydraulic fracturing process is done, the internal pressure that is among the structure will then allow the fluids used in the process to go up. People working in the field will make sure to place these fluids inside of the tanks and pits before they go for disposal or for some recycling.
People who work in hydraulic fracturing call the fracturing fluid that they have stored as flowback. Flowback can then be rid from the site with the use of two ways, that is the discharge of it to the surface water and having it go through underground injection. When the people who are in charge of either of these processes fail to get the job right, then the environment will have to suffer from its consequences.
It is thus the responsibility of the company to be sure that they get the right frac units available. You have to be very careful in choosing your hydraulic fracturing tools and equipment to be sure that you are not endangering the environment and the people that do their job around it.
