As debate rages on over the health impacts associated with
petroleum companies’ practice of hydraulic fracturing, or fracking, the
industry is coming up with a new but equally controversial technique to
get at oil and natural gas deposits thousands of feet below the surface
of the earth.
Californians are bracing for a new form of fracking that
uses pressurized gas to break up formations where oil is hidden instead
of the usual combination of water, silica sand and chemicals.
It’s called dry-fracking, and it’s expected to make its way to California communities soon if the oil industry has its way.
California is home to the Monterey shale, a geologic
formation that stretches from northern California to the Los Angeles
area. According to the U.S. Energy Department, the formation holds 15 billion barrels of untapped oil, accounting for more than is held in North Dakota’s Bakken oil region.
While the oil industry has long eyed the formation as a
source of big bucks, it has been met with opposition from the
agricultural community, vineyard owners included, as each fracking well
uses roughly 4 million gallons of water.
This new form of dry-fracking takes that argument off the
table, but it also brings along a new set of concerns for those working
to maintain the land of the Monterey shale region.
“(What) really scares me, first of all about the safety
during production because somebody could light a cigarette and there you
go, the whole town blows up,” Patricia Lerman, of the local advocacy
group Aromas Cares For Our Environment, told Central Coast News, a Fox affiliate station.
That’s not the only argument against dry-fracking. The
Center for Biological Diversity, based in San Francisco, has also come
out swinging against the emergence of the technique, claiming it’s too
early to know what the impacts could be if used in California.
Dry-fracking is already being practiced by at least two Texas-based companies, according to Central Coast News.
Gasfrac Energy Services Inc., a company based in Calgary,
Alberta, has an office in Houston and touts the new form of fracking as
one the company operates in a safe and reliable manner. According to the
company’s website,
Gasfrac patented its own waterless “Liquid Petroleum Gas” gel, which it
claims “yields higher reservoir production while eliminating concerns
over water use in fracturing.”
“While GASFRAC’s process inherently has different risks
from conventional fracture stimulation — our strong safety focus means
we’ve improved upon, and even advanced, certain safety features and
protocols, allowing for increased safety in oilfield operations,”
Gasfrac’s website says.
