In response to Nirmal’s blog regarding fracking,
though I honor your opinion that there are risks when hydraulic fracturing is
used, I feel there are basic facts that were left out that would be helpful.
This summer I have had the privilege to intern for a petroleum engineering firm
that consults with many companies and have had the challenge of researching
recycled “frac” water. To be more accurate Schlumberger defines hydraulic
fracturing as: “A Stimulation treatment routinely performed on oil and gas
wells in low-permeability reservoirs. Specially engineered fluids are pumped at
high pressure and rate into the reservoir interval to be treated, causing a
vertical fracture to open. Proppant, such as grains of sand of a particular
size, is mixed with the treatment fluid to keep the fracture open when the
treatment is complete. Hydraulic fracturing creates high-conductivity
communication with a large area of formation and bypasses any damage that may
exists in the near-wellbore area.” Your definition misleads because fracking
can be done either vertically or horizontally. Hydraulic drilling that was used
as far back as the 1860’s in which vertical hydraulic fracturing was used and
is still used today; therefore, stating that it is only horizontal would be
misleading.
You addressed the use of millions of freshwater from
areas in Michigan as a wasteful endeavor and equated it to the use of water
used in Texas. In general, fracking uses .5 - .8% of water the state uses
daily. Also, in the Permian Basin, recycling “frack” water is predominantly the
method used there and they are able to prevent unnecessary fresh water usage.
In fact, there are companies all over Texas that implement the recycling of
“frack” water despite the cost to the companies. Too, there are many companies
that now use a brackish water mix to lessen the use of fresh water. This is
vitally important in presenting this debate so the public is fully informed.
I appreciate your blog and the dilemma that fracking
presents to the everyday citizen, but would encourage further research. Based
on your pro and con list I can certainly see why you came to the conclusion you
made, but after further research I believe you would agree that fracking is
worth the risk.
