Hydraulic fracturing is among the well stimulation technique which the pressurized liquid will fracture the rock. This procedure involves the high pressure injection into a wellbore of fracking fluid to create cracks at deep rock formations which natural gas, brine and petroleum would flow more freely. When the pressure has been removed, the fractures would be held open with small proppant grains.
Groundwater is used usually for fracking fluid that is normally a problem because they could be used for drinking instead which is becoming a scarce source. That is why researchers, scientists, and engineers are developing a replacement with seawater frac. This will enable them in having more resources available that are usable for the needs they have instead of relying only with their current source.
Hydraulic fracturing has been around for more than seventy years now and millions of wells were fracked worldwide. Operators must obtain permits approved by regulators before they could drill wells which relates to well design, spacing, abandonment, location and operation. Environmental permits are also needed such as water and waste management and disposal.
Fracking occurs after the construction of well is finished and its integrity is confirmed but not during drilling. Among the most essential objectives is protecting groundwater and isolate these zones by designing and creating wells with steel casing and cement barriers. When drilling through these zones, fluids based on freshwater or air is used to prevent contamination.
They will not impact aquifers if performed safely and properly and the created fractures will not extend to them. These fractures were measured for determining their reach that shows their highest points still are far away from deepest aquifers. Some recent studies did not also find substantiated connection between fraccing and groundwater contamination.
Fracking fluid is normally composed of sand and water including chemical additives depending on which well to use it on. These elements which comprised them are also found in consumer products like cosmetics, table salt substitutes, ice cream, deodorant, toothpaste and household cleaners. When appropriately used and handled properly, the chemicals are safe.
These fluids are made specifically for the needs of each environment and factors like temperature, pressure, reservoir fluid composition, permeability, rock strength and mineralogy are addressed. Some companies would disclose what chemical ingredients they use to inform the public about it. This also protect the proprietary industry information and others even participate in national registry for chemical disclosure.
Significant volume of water for fracking operations is required similar with other process for manufacturing services, products and food people need everyday. This could be obtained from groundwater, treated wastewater, municipal suppliers and other available resources. Operators are encouraged normally to use, when possible, those unsuitable for consumption of humans and agriculture.
This procedure triggers seismic events rarely felt above on the surface of the earth because of their deepness. They release energy usually which will be equivalent with magnitude minus two in Richter scale and can not be detected upon the surface. For comparison, the rumbling of eighteen wheeler trucks that passes feels like a magnitude plus three.
