Conventional Wisdom
• The United States is on the verge of Energy Independence thanks
to the “SHALE REVOLUTION”.
• Shale Gas production will continue to grow for the foreseeable
future (2040 at least) and prices will remain low.
• The way is clear for U.S. LNG exports to monetize the shale gas
bounty.
• Shale gas production, although temporarily in decline, can be
turned around very quickly with a slight increase in prices. The sky
is the limit when it comes to increasing production.

The Shale Play Life Cycle
• Discovery followed by leasing frenzy.
• Drilling boom follows to meet “held-by-production” lease requirements.
• Sweet spots identified, targeted and drilled off. Companies always drill
their best locations first.
• Production rises rapidly and is maintained for cash-flow despite
potentially uneconomic full-cycle costs.
• Sweet spots become saturated and well quality and field production
decline.
• Plays like the Haynesville become middle aged after just five years.

- Shale has been a game-changer in the short-term, but projections
of long-term sustainability at low prices are highly questionable.
Summary and Implications
- Assuming long term sustainability of production at low prices is folly for energy policy. The shale revolution is a temporary windfall and
should be viewed as such.
- High quality shale plays are not ubiquitous – and plays are not
uniform. Sweet spots are exploited early in the development process.
The best parts of major plays are being drilled NOW.
35
- High well decline rates require a drilling treadmill and high capital
inputs to sustain production and offset field declines, along with
associated environmental impacts.
Page 36
Summary and Implications
- U.S. “Energy Independence” with the forecast energy trajectory is highly unlikely, barring a radical reduction in consumption and a major ramp up of renewable energy.
- A sustainable energy future requires a vision beyond the
next couple of quarters or the next election. In the absence of
a coherent plan, investments assuming cheap oil and gas in
the long term are
very likely to end badly.
