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. 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 done in order for the natural gas and oil to move easily to the production wells starting from the rock pores. These wells will then be capable of bringing towards the surface the oil and gas.
The creation of wells or other local structures is the beginning of the process of hydraulic fracturing. Drilling in vertical or directional/horizontal sections is what is usually being done among these product wells. Oftentimes, the standing well sections will then be drilled to the earth’s surface thousands of feet. Far from the production well, the horizontal sections of can go as far as 6000 to 1000 inches.
When the hydraulic fracturing process is done, fluids will be used to push into the geologic structure with the aid of high pressure. What these fluids contain are a mixture of water and some chemical additives. Usually, this process can only become a success if the amount of fluids that will be pushed through are thousands of gallons. 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.
The faults will be have a propping chemical pushed to it when the process has already reached the desired fracture that they need. 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.
The fracturing fluid that was collected at the end of the process is well known as flowback. Disposal of flowback could be done either by discharging it into the surface of the water or disposing it 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.
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. You have to choose your hydraulic fracturing equipment and tools carefully so that you can make the most out of it and get more benefits than the risks involved in not getting the process right or choosing the wrong company for the hydraulic fracturing equipment.
