Understanding Hydraulic Fracturing in Basic Terms
The process that is commonly used in removing oil, natural gas, geothermal energy, and water from the underground is what you call hydraulic fracturing. Hydraulic fracturing is one of the most beneficial processes being used in the gas and oil industries. This process is used in order for fracture system subsurface to be enhanced. This is crucial so that the natural gas and oil will not be having a hard time going to the production wells as they flow from the rock pores. These wells will then be capable of bringing towards the surface the oil and gas.
The process of hydraulic fracturing starts when the structures such as the wells are created. 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. And between 1000 and 6000 inches, the horizontal sections well be extended far from the production well.
Using high pressure in the hydraulic fracturing process, fluids will then be pushed going to the geologic structure. What these fluids contain are a mixture of water and some chemical additives. The hydraulic fracturing process thus requires thousands of gallons of such fluids. For the rock fractures to be weaker, high pressure must be applied; on the other hand, for the fractures to grow big, the chemical fluids will be the one responsible for them. This is made possible at very long distances that range a great thousand feet.
Once the fracture desired is attained, the faults will then be pushed with the use of a propping chemical. Before pumping more fluids, this process should be done so that these fractures that have been opened will just remain opened. The fracturing fluids going up happens at the end of the hydraulic fracturing process where the cause for this is the internal pressure from the structure. Such fluids can either be restored or disposed after they have been collected into tanks or pits.
People who work in hydraulic fracturing call the fracturing fluid that they have stored as flowback. Surface water discharge and underground injection are the two main methods of getting rid of this flowback. When this is done wrong, then there are more chances that it can be a threat to the environment and other surrounding life forms.
In order for the process of hydraulic fracturing to be done the best way, frac units available must be bought by the oil or gas company. This is why you have to choose the right manufacturer of the hydraulic fracturing tools and equipment that you will be using.
