1 Moving Beyond Misinformation: Education and Engagement

2 The Process

3 Misperception: Hydraulic Fracturing is Injecting Fluids into Groundwater

4 Drilling Distance Wells Fargo Center ~700 ft 7000 ft. Aquifer ft.

5 Casing  Multiple layers surrounding the aquifer  Cement  Conductor Casing  Cement  Surface Casing  Drilling Mud/Cement  Production Casing  Production Tubing

6 Surface Casing  Purpose Protect ground water Provide stable wellbore during drilling operation Provide well control during drilling  Depth Requirements Set by State and BLM regulations Extends below the aquifer  Cement Helps Protect casing from corrosion Provide zonal isolation Support casing in wellbore

7 Production Casing  Purpose Provide zonal isolation Provide well control Well path to productive intervals  Cement Requirements Set by State regulations Set by BLM regulations Operator requirements  Cement Helps Protect casing from corrosion Support casing in wellbore

8 Misperception: Hydraulic Fracturing is Not Engineered

9 Fracture Design  Data Required  Petrophysics/Formation properties  k, Φ, ν, E, σ, Pp, BHT  Fluid properties  Multitude of fluid types  n’, K’, μ, break profile, Pf,  Proppant properties  Variety of proppant types  β, sg, size, CD Predict-K 3.0

10 Pump Schedule  A pump schedule is required for the simulator to determine the predicted fracture geometry Fluid and proppant volumes Treatment rate Additive rates Frac Job

11 Treatment Graph Frac Job

12 Misperception: Drilling is Getting Riskier

13 Fractured Contact

14 Footprint 1 Well Pad or 32?

15 Misperception: Drilling and Hydraulic Fracturing Uses Too Much Water

16 Colorado Water Use Total (Million gallons/Day)Total (Billion gallons/Year) Irrigation (crop)12, Irrigation (golf course)4114 Public-supply Domestic3412 Industrial14252 Livestock3312 Mining218 Thermo-electric12345 Total withdrawals13, Source: USGS 2005 Estimated Withdrawals and Use of Water in Colorado, 2005

17 Horizontal Well Activity  2011  517 Horizontal wells permitted   220 Horizontal wells spud  Example:  1,000 wells x 5M gal = 5B gal  0.11% of Colorado annual irrigation water use  0.10% of Colorado annual water use

18 Estimate All Well Activity  2010  2098 wells completed  2011 Estimate Water Use  1000 horizontal wells (5M gal)  1500 vertical wells (1M gal)  Conservative Estimate:  0.14% of Colorado annual irrigation water use  0.13% of Colorado annual water use

19 Water Requirements  Natural gas has one of the lowest water usage rates per MMBTU

20 Misperception: There is No Data Showing Groundwater is Protected

21 COGCC  Groundwater complaints  Hundreds of complaints  No verified instances of hydraulic fracturing harming groundwater in Colorado  Water sampling  Since 2000, baseline and periodic water sampling for over 2,000 water wells in the San Juan Basin  Independently verified; no significant increase in chemical concentrations

22 Meaningful Engagement and Education

23 FracFocus Website 23

24 HF Disclosure Example

25 Baseline Water Sampling  Pre and Post-drilling water samples taken around new well starts  Increased transparency & accountability for industry

26 COGA Fast Facts

27 Resources  Hydraulic Fracturing Fact Sheet  COGCC Gasland Correction Document  COGA’s The Truth About Gasland  Other Fact Sheets Natural Gas Facts Socioeconomic Benefits Produced Water Natural Gas Supply

28 Questions? Thank you for your interest in Colorado’s oil and gas industry!
