Hydraulic fracturing using high pressure liquids to break rocks can be used to access deep reservoirs of <u>crude oil. </u>
<h3>What is the use of hydraulic fracturing?</h3>
In a process known as fracking, hydraulic fracturing is done when a fluid is injected into rocks far below the surface.
The aim of this process is to get the rocks to break apart which would then allow the deep reserves of oil to be accessed. This is a major process of crude oil production in the United States.
