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. This process is used in order for fracture system subsurface to be enhanced. This is done in order for the natural gas and oil to move easily to the production wells starting 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. 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. 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. These fluids are formed with the aid of water being mixed with certain chemical additives. These fluids are needed in about a thousand gallon of amount. 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 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. 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. 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.
The fracturing fluid that was collected at the end of the process is well known 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.
Carefully choosing the frac units available to be used by the company is crucial to the success of the entire hydraulic fracturing process. 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.
