Summary: Fracking Fracking supplies 20% of US oil production (10% of consumption) and 40% of US natural gas There are only two highly productive oil shale sites, Bakken in North Dakota and Eagle Ford in Texas. Both are expected to peak by 2017 and then decline Fracking wells decline by 60% the first year and 90% in 3 years. Almost 50% of wells need replaced annually—5000 new wells/year for gas and 4000 for oil. Each well uses about 2 million gallons of water—all of which becomes polluted--and 15,000 gallons of toxic chemicals The EROEI of fracked oil & gas is low– 3:1 for oil and 5:1 for gas Most fracking sites will be depleted by 2020 52
53
Summary: Tar Sands Currently 1.7 million barrels of tar sands oil are produced daily (the US consumes a total of 18 mbd) About 10% of US gasoline comes from tar sands About 200 square miles of land has been strip mined to date. The tar sands industry uses about 44 billion gallons of fresh water per year, all of which is polluted. There are 50 square miles of toxic sludge ponds holding the polluted water used in the production process. The EROEI of tar sands is low, about 5:1 for surface material and 3:1 for the deeper (in situ) material 53

Conclusion: The U.S. is a mature exploration & development province for oil and gas (i.e. there are no more big fields to be discovered). This is also true for the world; there are few large reserves left to find. The U.S. cannot drill and frack its way to “energy independence.” Fossil fuels are finite, and production of new fossil fuel resources tends to be increasingly expensive and environmentally damaging. We can’t run American society as it current exists on low energy-return fuel (5:1 for fracked gas, 3:1 for fracked oil and tar sands). A new energy dialogue is needed in the U.S—but isn’t going to happen. A decrease in the size of the US economy is almost surely imminent. 54
