HOUSTON, Feb. 21, 2013 /PRNewswire/ -- Cabot Oil & Gas Corporation (NYSE: COG)
today reported year-end 2012 proved reserves of 3.8 trillion cubic feet
equivalent (Tcfe), an increase of 27 percent over year-end 2011. This is 100
percent organically generated growth and represents the third consecutive year
of reserve growth exceeding 20 percent, after adjusting for the sale of its
Rocky Mountain properties in 2011. Total reserve replacement from all sources
was 417 percent at a finding cost of $0.87 per thousand cubic feet equivalent
(Mcfe). "In spite of a 33 percent decrease in the benchmark natural gas price
used in calculating proved reserves in 2012, we grew year-end proved reserves
significantly without an increase to our PUD percentage," said Dan O. Dinges,
Chairman, President and Chief Executive Officer. "Our all sources finding cost
of $0.87 per Mcfe is our lowest in 15 years and further highlights the capital
efficiency of our portfolio."

Cabot's reserve growth was primarily driven by its drilling programs in the
Marcellus Shale, Eagle Ford Shale and Marmaton oil play, which resulted in
926.8 billion cubic feet equivalent (Bcfe) of additions for the year. The
Company reported an additional 369.6 Bcfe of positive revisions for the year,
primarily as a result of performance improvements in the Marcellus Shale. The
Company also recognized 114.5 Bcfe of negative price revisions due to lower
natural gas prices in 2012 and 66.5 Bcfe of negative revisions due to
reclassification of legacy East Texas proved undeveloped (PUD) reserves to the
probable category in compliance with current Securities and Exchange
Commission regulations.

Marcellus Shale proved reserves increased more than 51 percent in 2012 as a
result of the continued success of Cabot's drilling program in the play. This
increase included 420.8 Bcf of positive performance revisions due to increased
reserve bookings on producing/drilled wells and increased reserve bookings on
PUD locations from an estimated ultimate recovery (EUR) of 7.5 Bcf to 9 Bcf
per well. All sources reserve replacement for the Marcellus Shale properties
was 603 percent at a finding cost of $0.49 per Mcf, 25 percent lower than the
$0.65 per Mcf in 2011. "Our Marcellus program continues to demonstrate
outstanding results.Our 2012 drilling program's average producing Marcellus
well was drilled with a 4,087 foot useable lateral length and completed with
17.6 frac stages yielding an EUR of 13.9 Bcf per well," commented Dinges. "As
we continue to drill longer lateral wells and utilize reduced frac stage
spacing across the entire Marcellus program, we anticipate additional
increases in EURs, further improving our already superior well economics in
the play."

Natural gas represented approximately 96 percent of the Company's year-end
2012 proved reserves, in line with year-end 2011. Cabot's undrilled PUD
reserves percentage remained flat at 36 percent while the overall PUD
percentage decreased slightly to 40 percent. Similar to prior years, the
Company took a conservative approach to its PUD bookings in the Marcellus
Shale recognizing 0.7 offset PUD locations for each of its proved developed

The Company's reserve base continues to be comprised of long-lived assets with
a total reserves-to-production ratio of 14.4 years. "Based on our current
estimates of identified drilling locations, we have a significant amount of
running room with over three decades worth of drilling opportunities based on
our planned 2013 drilling activity," stated Dinges.
