Market Opportunity?
Energy Information Administration Natural Gas
Monthly October 2000 Quote for Rocky Mountain
Region





Expanding coal-bed methane production has
outpaced the development of long-haul capacity to
carry the gas to end-use markets. Capacity
constraint problems exiting the production areas
have resulted in the region having the lowest
average natural gas spot prices in the nation.

Rockies Production Growth
99 Years of Continuous Quality Service
S O U T H E R N S T A R C E N
T R A L G A S P I P E L I N E

• Production in Wyoming totals about 4.2 Bcfd now
  and if environmental and regulatory delays can be
  cleared, could grow to in excess of 6 Bcfd over
  the next 5 years
• Wyoming state budget is heavily dependent upon
  revenues received from mineral production
  produced from state federal lands. During the
  past 5 years, natural gas production has grown
  almost 50 in the state, with limited additions
  to the infrastructure to export growing
  production

• Mid-Continent Production
• Richard Sharples, President of Anadarko Energy
  Services on the status of Mid-continent supplies
  
• The Mid-continent is so mature that it doesnt
  matter how much you drill, you wont increase
  production

• Atmos, Kansas LDC Seeks Gas from Rockies
• Atmos has determined that declining gas supplies
  in the Mid-continent region, including gas
  supplies it currently purchases from wells in the
  Kansas Hugoton and Panoma Council fields,
  threaten Atmos ability to continue to provide
  and maintain a reliable source of gas.
• This along with increased demand due to
  gas-fired electric generation, has resulted in
  increased pressure on the price of gas produced
  in the Mid-continent region
• Historically, Rocky Mountain gas supplies have
  been less expensive than Mid-continent gas
  supplies due primarily to lower finding costs.

T R A L G A S P I P E L I N E

• Gas Market will Remain Tight in Near Term
• Leaves Market Vulnerable to Price Volatility
• Long Term Focus is Key
• State Commission Education Necessary
• If Environmental Regulatory delays can be
  cleared Wyoming Production could Grow from the
  current 4.2 Bcfd to in excess of 6 Bcfd over the
  next 5 years
• New Infrastructure will be required to get this
  gas to Market
• Supply Diversification Needed in the
  Mid-continent
• Rockies Gas can provide Long Term Solution for
  Mid-continent Markets
• Western Frontier Project Situated to meet Market
  Needs Quickly Efficiently with Market Support

• Supply Diversification Necessary
• Rockies Supply Prolific needs Additional Market
  Access
• Basin Diversification
• Cheyenne Hub
• Denver Julesburg (DJ) Basin
• Average Differential Between Rockies-Cheyenne Hub
  and Mid-Continent Inception to Present 0.80
• Dynamic Operating Hub - Additional Infrastructure
  Needed out of Cheyenne Hub
• Diverse Market Access Providing Liquidity
• Market Growth
• Oklahoma Intrastate Market
