The commonly known Fracking or fracking, is a drilling method that is used to extract not only oil but also natural gas from the underground depths.
The hydraulic fracturing transgresses environmental and political levels very debated. Advocates of Fracking argue that it is this way of subtracting energy is a safe and cost-effective source of obtaining clean energy; Those who criticize the method, cause damage to the environment such as destroying drinking water supplies, polluting the air, contributing to greenhouse gases that cause global warming and triggering earthquakes, among many others.
How the fracking operates
Most of the FH wells used today are complemented by the first two technologies; The hydraulic fracturing, which is used since the decade of 1940, and the second call; Horizontal perforation, a technique that was implemented in the decade of 1990, as it has been embodied in books of Columbia University.
In simple terms, the fracking process begins with a well that is drilled vertically or at an angle from the surface to a depth of 1 to 2 miles or more, this depends on the need for the area to be drilled, as noted by the WBA Protection Agency. Iental of the United States. Then, the vertical well is covered with steel and cement, which guarantees that the well does not run the risk of leakage in groundwater.
