Shale Gas: Myths and RealitiesLong-term Sustainability and Implications for Future

Energy Security

Points to be covered:

- SHALE GAS – A look at the fundamentals with examples from

major U.S. plays

-The SHALE REVOLUTION and

CONVENTIONAL WISDOM

- IMPLICATIONS for long term energy sustainability

2

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.

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.
