Ch. 25: Gas Pains

Presented by Derek Nordby

there ain t no such thing as a free lunch
“There ain’t no such thing as a free lunch”
  • Every form of energy is going to come with a cost to humans/the environment.
    • Hydropower
      • Flooding of rivers and streams.
    • Oil & gas
      • Land usage for drilling an pipelines.
      • Oil spills.
    • Coal
      • Mines tear up the land.
    • Hydrocarbon combustion
      • Large quantities of CO2 emissions.
slide3
Gas
  • Hydraulic fracturing is used in extraction
    • Additives cause concerns about water regulations.
    • 2004: EPA study says that there is no evidence that fracturing is a danger to drinking-water.
    • IPAA claims >1 million wells have been drilled in the past 50 years and no documented cases of contaminated drinking-water.
    • Lustergarten reports on ground water contamination in WY.
    • 2009: EPA does 2nd study and finds 11 of 34 wells contaminated.
politics
Politics
  • Industry opponents want more federal oversight.
  • Determining where some companies are drilling.
  • While site locations are being limited, the U.S. still needs many new wells.
well production
Well Production
  • Some new wells’ production will drop 80-90% within the first year.
  • Overall well productivity is also decreasing.
    • 1971: 435,000 ft3/day
    • 2008: 113,000 ft3/day
  • Forces companies to look for new wells.
    • 2008: 60,000 new wells in U.S.
upsides
Upsides
  • Gas industry continues to improve.
    • Drilling from farther away.
      • TCU Horned Frogs’ stadium.
  • Water usage is not as big of a deal as it’s made out to be.
    • Marcellus Shale (Pennsylvania)
      • If increased to drilling 3,000 wells/year
        • 30 million gallons of water each day
    • Pennsylvania electric sector
      • ~5.9 billion gallons/day (200x more than natural gas projections)
conclusion
Conclusion
  • Natural gas is not a perfect fuel, but it is the greenest of the hydrocarbons.
  • In order to get away from using hydrocarbons, we have only one choice.
  • Nuclear power.
