The process that is commonly used in removing oil, natural gas, geothermal energy, and water from the underground is what you call hydraulic fracturing. For people working in the gas and oil industries, they make sure to utilize hydraulic fracturing in their processes. They use this process to be able to increase the subsurface that you can find among fracture systems. 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. It will then be the job of the wells to bring to the surface the gas and oil retrieved.
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. Oftentimes, the standing well sections will then be drilled to the earth’s surface thousands of feet. 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. These fluids are formed with the aid of water being mixed with certain 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 can be done at very long distances some even reaching several thousands of feet.
When the choice of fracture is achieved, there will be a particular propping chemical that will be pushed into the faults. This is being done so that the fractures and faults will be able to stay open as the fluids that are being pumped will be released. 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. Such fluids can either be restored or disposed after they have been collected into tanks or pits.
The term flowback is what you call the fracturing fluid that was collected yet again. Disposal of flowback could be done either by discharging it into the surface of the water or disposing it through underground injection. The environment will be put at extreme harm when the both of these processes are being done the wrong way.
It is thus the responsibility of the company to be sure that they get the right frac units available. This is why you have to choose the right manufacturer of the hydraulic fracturing tools and equipment that you will be using.
