Hydraulic fracking, sometimes called hydraulic drilling
Hydraulic firming, hydraulic fracturing, hydraulic fusing, or hydraulic cracking, is an engineering method for drilling into heavy mineral-bearing rocks with the help of a fluid propelled at high velocity through the borehole. This fluid contains high pressure and may be mixed with bitumen or clay. The process may also involve injecting water or injection of other fluids for the purpose of helping to lubricate or seal fractures.
The main reason behind hydraulic fracturing is the utilization of natural gas as a fuel. The gas is trapped in the shale layer of the earth and has the potential to be pumped out when the rock fractures. The fractured rocks contain huge volumes of natural gas, which can be tapped for use as fuel. The technique can be used to extract oil from wells which are located in difficult geographical locations and are found on steep slopes. However, environmentalists have raised questions on the effect of hydraulic fracturing on the environment.
Before the practice was introduced, large-scale commercial production of natural gas from wells was difficult. As a result, most of the gas was produced on a small-scale basis, which resulted in severe air pollution and huge environmental damage. Today, the drilling of hydraulic fracturing involves smaller scale operations which do not result in significant air pollution or damage to the environment. Moreover, the drilling techniques have made the extraction of gas from horizontal wells more efficient than the past.
The technique of hydraulic fracturing involves the injection of liquid sodium
The wellbore in order to break the fracture. The fractures are usually deep inside the earth’s surface so that they cannot be accessed by traditional means like hand digging. This requires the drilling of horizontal wells. Once the fracture is broke, it is transferred to the injector which uses hydraulic pressure to pump the newly formed fracture into the earth’s crust. This process of fracture transport involves movement of the fractured material through fractures in the earth’s surface. The injector further injects pressurized liquids at the fractured area in order to promote the movement of the fractured material even further.
Hydraulic fracture drilling has revolutionized the production of oil and gas. In this method, large volumes of water and thick rock can be pumped out by using massive amount of hydraulic pressure. This method is very popular in geology and mining. Moreover, it has many other advantages over alternative methods like manual digging and mining. The drilling of this method is also safe, as there is no threat of accidents related to earthquake and other natural disasters.
This method of hydraulic fracturing is mostly used to extract oil and gas from deep within the Earth’s surface. The cost of the process depends on various factors including the type of fractures being used and the size of the fracture. This method has made the extraction of oil and gas from deep within the Earth’s surface extremely easy. In fact, the cost of this method is only a small fraction of what it would cost for traditional methods to be used. Moreover, it has many other advantages as well.
