The chances of
anyone mishearing the word ‘fracking’ are thick; resulting in raising eyebrows
toward the manners of the speakers. Nevertheless, if the word is heard
correctly, you will know it is among the significant ways of extracting oil and
natural gases from oil shale. Referred to as hydraulic fracturing, the process
came into existence in 1903, but it took close to 50 years to use the technique
commercially. The entire oil extraction procedure has undergone a sea change
with the advent of hydraulic fracturing.
The working of
hydraulic fracturing
The process of
hydraulic fracturing is initiated by pumping the liquid via a well to an
underground shale deposit; this liquid creates immense pressure on the shale,
causing it to break and release oil or natural gas. The most preferred liquid
agent to be used in the process of fracking is water; however, sometimes crude
oil, diesel oil, kerosene or diluted hydraulic acid can be used. Whenever, water
is used as the liquid during fracking, it has to be mixed with certain
chemicals and gaur, giving it a glutinous property.
Which parts of
the world use hydraulic fracturing?
The gains from
fracking have been aplenty. Some parts of the world that extensively use hydraulic
fracturing process are the UK, Columbia, Argentina, Indonesia, Russia, Venezuela,
Romania, Brazil, France and parts of the US. Being an indirect benefit,
hydraulic fracturing has helped creating employment opportunities in several
sectors such as hospitality, construction, engineering & surveying,
equipment manufacturing, and electromechanical actuators.
By blending
fracking with other technologies, the extraction of oil and natural gases from
oil-bearing shale has become simpler and more profitable. The supporters of
hydraulic fracturing assert that the process is, by far, the best natural gas and
oil extraction technique, which is changing the face of global Energy
industry. The fracking process has
opened the doors to oil and gas reserves that were earlier unreachable.
