Boom Fuels Demand for Key Ingredient Used in Drilling Wells
The race
to drill for oil in the U.S. is creating another boom—in sand, a key ingredient
in fracking.
Energy
companies are expected to use 56.3 billion pounds of sand this year, blasting
it down oil and natural gas wells to help crack rocks and allow fuel to flow
out. Sand use has increased 25% since 2011, according to the consulting firm
PacWest, which expects a further 20% rise over the next two years.
In
Wisconsin, the source of white sand perfectly suited for hydraulic fracturing,
state officials now estimate more than 100 sand mines, loading, and processing
facilities have received permits, up from just five sand mines and five
processing plants operating in 2010.
And the
stocks of publicly traded companies that deal in sand have soared. Shares of
Houston-based Hi-Crush Partners LP have
jumped 59% since it began trading in August 2012. Shares of U.S. Silica Holdings Inc., based
in Frederick, Md., have doubled since it went public in 2012, giving it a stock
market value of $1.9 billion.
Less than
a decade ago, U.S. Silica focused on sand for industrial and consumer
products—plate glass for windows and, more recently, glass for iPhone and iPad
screens. Now those uses account for just half the sand the company digs out of
its open pits and even less of revenue.
During the
first nine months of this year, the more than $245 million in sand sold to
energy companies accounted for 62% of U.S. Silica's sales, up from 53% during
the same period in 2012 and 33% during the first nine months of 2011.
Hydraulic
fracturing is the process of pumping a mixture of sand, chemicals and water
down a well at high pressure to break up dense rock formations so that oil and
gas can flow to the surface. The sand left behind in the fracking process props
open those tiny pathways so trapped fossil fuels can escape.
