FRACKING
By Anton Antonio

“Fracking” is really not a misspelled obscene word that most
of us are familiar with. No need to call
the attention of MTRCB on this one. The
term “fracking” is shorthand or slang for hydraulic fracturing and refers to
how deeply embedded ground rock is fractured apart by the high pressure mixture
of water, sand and chemicals. Other
terms associated with fracking are “frac job” (the actual work being done) and
“frac unit” (the people doing “frac jobs”).
Fracking or hydraulic fracturing is the process of drilling
down into the earth using a high-pressure water mixture directed at the rocks
to release the gas inside them. It is a
well-stimulation technique in which rock is fractured by pressurized liquid. Water, sand and chemicals are injected into
the rock at high pressure which allows the gas to flow out to the head of the
well. The process involves the
high-pressure injection of fracking fluid, composed of water, sand and other
proppants suspended with the aid of thickening agents, into the wellbore to
create cracks in the deep-rock formations through which natural gas, petroleum
and brine will flow more freely. When
hydraulic pressure is removed from the well, small grains of hydraulic
fracturing proppants (either sand or aluminium oxide) hold the fractures open.
Hydraulic fracturing began as an experiment in 1947 and the
first commercially successful application followed in 1950. As of 2012, 2.5 million “frac jobs” had been
performed worldwide on oil and gas wells, over a million of those in the United
States.
Hydraulic fracturing is highly controversial in many
countries since, according to environmental groups opposed to fracking, the
potential environmental impacts out-weigh the economic benefits, which include
risks of ground and surface water contamination, air and noise pollution, and
potentially triggering earthquakes, not to mention the consequential hazards to
public health and the environment in general.
At present, there are three major concerns on fracking as a
means to produce fossil fuel, these are: (1)The huge amount of fresh water
requirement which will impact on agricultural productivity; (2) The possible
carcinogenic contamination of groundwater around the fracking site which may lead
to wider health issues for those living in the periphery of fracking sites;
and, (3) The small tremors or earthquakes of 1.5 to 2.2 magnitude that the
production system and technology produces which has destructive effects on
aquifers. Fracking industry proponents,
however, suggest that environmental and pollution problems are the result of
bad practices rather than an inherently risky production technique. Pro-environment advocates and activists, on
the other hand, say that, with the advent of global warming and climate change,
the fracking industry will have to look for green and alternative power sources
which are renewable. The use of
materials such as lead, uranium, mercury, ethylene glycol, radium, methanol,
hydrochloric acid and formaldehyde makes a lot of people frown and question the
propriety of the use of these chemicals and materials which may cause a lot of
health problems.
The real issue is the relative economy by which 300,000
barrels of natural gas produced daily in the largest fracking operation in the
U.S. alone as opposed to the displacement of the entire industry caused by a sudden
shift to renewable energy. One question
that should be answered by the fracking industry is the sustainability of the
practice of hydraulic fracking. Climate
change is real and the fracking industry will have to also sacrifice for us to
be able to avert and mitigate the ill effects of global warming. Change does not necessarily have to be
sudden; gradual will be acceptable so long as change is programmed. All fossil fuel production technologies will
have to really be reviewed (for our sake and the future generations)… including
the practice of fracking.
