THE 2012 LAHERRERE’S VISION
Ultimate reserves: 13 Pcf = 10.4 Pcf conventional + 2.6 Pcf unconventional
World production peaks at nearly 150 Tcf/y
If unconventional
gas is > 2.6 Pcf,
the peak is not
changed but
the decline
is slower
B/ THE RISE OF SHALE GAS
IN THE UNITED STATES
MAIN SHALE GAS DEPOSITS
THE US SHALE GAS EARLY DAYS
• 1970-2000: Unconventional gas (on average 70% tight gas,
20% CBM and 10% gas shale up to 2008) has grown slowly
from less than 1 Tcf/y in 1970 to ~5 Tcf/y in 2000
• 2000-2008: Unconventional gas was foreseen to reach a 9
Tcf/y plateau in 2010-25, but the fall of conventional gas was
such that much increased LNG imports were to be needed
• 2008: Oil, natgas prices, and the US rig count, collapse. To
maintain their production, operators deploy new technologies,
which are at the origin of the shale boom
Because of their belief that LNG imports were set to grow,
many operators have developed LNG terminals now idle

C/ FUTURE PERSPECTIVES
FOR THE US SHALE GAS
THE VOICE AGAINST SHALE GAS
Contrary to the major limitations that Arthur Berman sees…
• High costs, poor economics and destruction of capital,
• Infrastructure limitations (pipelines and NGL-stripping plants),
• Physical fundamentals (small core areas, fast decline rates),
• Average break-even prices higher than current prices,
…One may be optimistic about the future of shale gas
• Shale gas development is not like a Ponzi scheme…
• …and US gas majors are not behaving like Madoff.
• Some operators may fool some analysts for a while but…
• …the entire industry cannot be wrong for ever
TRUE SHALE GAS REALITIES
• Shale gas is the last unconventional gas in development,
and still is at the beginning of its learning curve.
• The pace of technological improvement will continue
• Expected ultimate reserves critically depend on the type
of decline (exponential or hyperbolic)
• High costs plays: Liquids (oil or NGL) are essential for
the economics
• Core areas with good IP are small (a few %), but overall
reserves may be very large
• Good operators will manage environmental concerns
• Infrastructure (NGL plants and pipelines) is critical
US PRODUCTION GROWTH
Shale gas dominates the natural gas growth
WHAT CHESAPEAKE SAYS
WHAT THE US DOE-EIA SAYS:
US dry natural gas production forecast in the AEO-2012:
Growing from 5 Tcf in 2010 to 14 Tcf in 2035!
D/ AND WHAT ABOUT
ELSEWHERE IN THE WORLD?
UNCONVENTIONAL TRANSPORT
OF METHANE IN CHINA (1997)
CANADA SHALE RESOURCES
With resources of 1100 Tcf, 200-300 Tcf may be recoverable
A total of 1100 TCF
of which ~50% in
the Horn River Basin
AND WHAT ABOUT THE WORLD?
First feedbacks are good for Argentina, possibly
good for China (?), uncertain for Europe and Ukraine
6600 Tcf or 6.6
Pcf of which 2-3
recoverable?
CONCLUSION: WHAT FUTURE?
• In North America: Exports of a few % of production
as LNG will sustain a balanced price level (5-6 $/kcf)
which, in turn, will allow production to grow evenly.
• In Europe: Unconventional gas prospects are remote:
not only spot LNG imports push prices down but the
EU E&P legislation needs to be deeply redrafted
• In Asia-Pacific: Neither China unconventional (still far
away), nor Australian CBM-to-LNG (a few Bcf/d) will
be game changers and decouple LNG from oil soon.

CBM production in 2007: 4.8 Bcf/d (9% of total US dry gas)
• Canada – since 2002: 208 Mcf/d in 2007. Could exceed 1.4
Bcf/d by 2015. Average new well on stream at 100 Mcf/d.
• Australia – since 1996; 215 Mcf/d in 2006; Queensland
produced 272 Mcf/d in 2007; planning up to 6 LNG schemes
near port of Gladstone.
• Minor production or approaching commercial production:
UK; China; India; Kazakhstan; Russia (Kuznetsk Basin).
• 13 coal-producing countries have CBM projects.

TIGHT SANDS RESOURCE PLAYS
Basin-Centered Gas
Gas dissolved in abnormally-pressured low-permeability
aquifers in the central (generally deeper) part of basins • over-pressured in subsiding basins
• under-pressured in uplifted and eroded basins.
Also known as “deep gas” and “tight sand gas” but these are
not necessarily restricted to continuous accumulations (and
BCG is not always deep).
Examples:
San Juan Basin & Greater Green River basins (USA);
Western Canada Sedimentary Basin (southern deep basin);
Northwest Europe Permian Basin; Pannonian Basin;
Algerian basins; Oman Basin; Ordos Basin, China.
33
TIGHT SANDS RESOURCE PLAYS
Resources of tight Sand Gas / Basin-Centered Gas
Enormous in-place resources in USA (all tight sands)
• 3,000-5,000 Tcf in the Greater Green River Basin;
• 900 Tcf in the Wind River Basin, Wyoming;
• Total in-place resource ~ 7,000 Tcf.
USA Ultimate Tight Sand Resource Estimate
• 380 Tcf: 140 produced, 60 proved, 180 unproved/undiscovered,
200 Tcf produced and proved considered as “conventional”
• USA unproved/undiscovered BCG resource estimates from other
sources range up to 340 Tcf.
No reliable global resource estimate available
34
TIGHT SANDS RESOURCE PLAYS
Production of tight Sand Gas / basin-centered gas
USA production from all tight sands
• Total US production estimated at >6 Tcf (16.5 Bcf/d) in 2007
• 5-6% recovery factor - but much higher from “sweet spots”:
- Pinedale: 56% (10-acre spacing);
- San Juan Mesaverde: 44% (160-acre spacing);
- Uinta Mesaverde (EOG): 37% (10-acre spacing);
- Jonah Lance: 30% (40-acre spacing).
Canada
• Canadian production from tight sands and carbonates:
- Alberta: ~3 Bcf/d;
- British Columbia: ~1 Bcf/d.

USA Ultimate Fractured Shale Resource Estimate
• ~415 Tcf: 9 produced, 21 proved, 385 unproved/undiscovered
(ICF International). 30 Tcf produced + proved is considered
“conventional”.
• Unproved / undiscovered shale gas recoverable resource
estimates from other sources range from 32 Tcf to 125 Tcf but
predate recent improvements in recovery and assessment of
recent plays such as Haynesville and Marcellus.
Global Resource Estimates
• No reliable estimate available but considerable potential exists.
• Canada (BC; AB; QC; NB; NS) will be next significant player.
Estimated 860 Tcf IP in Western Canada (130 Tcf recoverable).
