The
new
data,
released
Tuesday,
estimate
that
the
rich
shale
play
contains
84
trillion
cubic
feet
of
“undiscovered,
technically
recoverable”
natural
gas
and
3.4
billion
barrels
of
natural
gas
liquids.
The
last
estimate,
in
2002,
pegged
the
basins
as
containing
about
2
trillion
cubic
feet
of
gas,
the
USGS
said.
While
higher
than
prior
USGS
estimates,
the
new
data
also
tempered
information
from
the
US
Energy
Information
Administration,
which
estimated
reserves
as
high
as
410
trillion
cubic
feet,
Bloomberg
reported.
It’s
the
latest
chapter
in
an
ongoing
debate
over
the
potential
of
America’s
shale…
