Fluid Demo

How much water is used?• 50,000 bbls or 2.1 million gals per well• 0.08% of Colorado’s water use in 2010

• Greeley’s water use for oil and gas was 2% in 2011, they released 36%.

• Flowback and produced water can be recycled.

• Water not taken out of the water cycle.– CH4 + 2O2 CO2 + 2H2O + Energy

• 1 BCF of methane gas yields 11 million gals of water
