Important Hydraulic Fracturing Facts You Need to Know
The process that is commonly used in removing oil, natural gas, geothermal energy, and water from the underground is what you call hydraulic fracturing. 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 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. These production wells are typically drilled either in vertical sections or directional/horizontal sections. Usually, it takes thousands of feet for the standing well section to be drilled deep into the earth’s surface. 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. These fluids are needed in about a thousand gallon of amount. As the pressure gets higher, the rock fractures become weaker and with the aid of chemical fluids, the fractures will be enlarged. 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. 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. These fluids must first be collected in tanks and pits before they will be disposed or recycled.
The term flowback is what you call the fracturing fluid that was collected yet again. Surface water discharge and underground injection are the two main methods of getting rid of this flowback. 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. This is why you have to choose the right manufacturer of the hydraulic fracturing tools and equipment that you will be using.
