  1. Fracking Session American Planning Association Conference - CO Chapter October 2012

  2. Ensure: Exploration and production of oil and gas resources are conducted efficiently. Mineral owners’ rights are protected. Oil and gas production is conducted in a manner consistent with protection of public health, safety, and welfare, including the environment & wildlife resources. COGCC MISSION PROMOTE THE RESPONSIBLE AND BALANCED DEVELOPMENT OF COLORADO’S OIL & GAS RESOURCES

  3. REGULATIONS • 100 Definitions • 200 General • Drilling, Development, Procedure, and Abandonment • 400 Units, Enhanced Recovery, and Storage • 500 Hearings • 600 Safety • 700 Financial Assurance • 800 Aesthetic and Noise • 900 Waste Management • 1000 Reclamation • 1100 Pipelines • 1200 Wildlife

  4. PERMITTING PROCESS • APPLICATION FOR PERMIT TO DRILL • APD • FORM 2 • Provides information regarding the permitting of the wellbore and its construction. • Surface & bottom hole location • Casing • Cementing • OIL AND GAS LOCATION ASSESSMENT • OGLA • FORM 2A • Provides an assessment of surface location. • Area of disturbance • Environmental review • Hydrology • Groundwater • Surface water • Inter-agency consultation

  5. DRILLING PERMIT Well Location Lease, Spacing, and Pooling Information Drilling Plans and Procedures

  6. PROTECTING WATER • Technical reviews of casing and cementing plans. • Review of surrounding area hydrology, water wells and surface waters. • Baseline water sampling; post-drilling sampling. • Review of operator-provided Best Management Practices to protect water, contain potential spills.

  7. COGCC RULES PREVENT WATER/GAS/OIL MIGRATION • ENSURE SURFACE CASING IN ALL WELLS IS SET AT LEAST 50 FEET BELOW THE DEPTH OF THE DEEPEST WATER WELL OR AQUIFERS • ENSURE PRODUCTION CASING ISOLATES ALL HYDROCARBON BEARING ZONES

  8. Wellbore Construction • COGCC Rule 317 mandates • Concrete and steel casing protect the aquifer and are cemented in place & to the surface • Natural gas producing formations – separated by more than a mile of solid rock with concrete isolation across zones. • Drill with clear water to set surface casing • Add bentonite clay and ph control agent to help thicken bentonite (improve yield) • Drilling reserve pit is reclaimed in the same order it was built – top soil last in. • Many operators currently use closed loop drilling process – no pit.

  9. FRAC JOB – WELL SITE FRAC FLOW BACK TANK SAND MOVER WATER TANKS COMMAND CENTER CHEMICAL TRUCKS

  10. COGCC Hydraulic Fracturing Rules • Rule 205 Inventory chemicals • Rule 205A Disclosure • Rule 317 Well casing and cementing; Cement bond logs. • Rule 317B setbacks and precautions near surface waters and tributaries that are sources of public drinking water. • Rule 341 monitor pressures during stimulation. • Rule 608 Special requirements for CBM wells. • Rules 903 & 904 pit permitting, lining, monitoring, & secondary containment • Rule 906 requires Commission, CDPHE and the landowner of any spill that threatens to impact any water of the state.

  11. WATER DEMAND AND SOURCES • Hydraulic fracturing accounts for about 1/10 of 1% of Colorado’s annual water use. • The amount of water used for hydraulic fracturing is roughly comparable to the amount of water used in Colorado for snowmaking. • Operators can procure water from various sources but must adhere to state water law when obtaining and using it.

  12. HYDRAULIC FRACTURING • More than 90% of oil and gas wells today are hydraulically fractured. • As of April 1, 2012 operators must disclose all fracturing ingredients and concentrations to FracFocus.org. Operators must file paperwork to certify proprietary claims. • Rules require cement bond logs and pressure monitoring to ensure integrity of well and cement work.
