5 Shale Basins in North Carolina
Chatham Lee Reid, J.C and R. C. Milici, 2008 US Geological Survey and NC Geological Survey are completing a resource assessment in Spring 2011. NCGS has estimated 59,000 acres may have gas resources. (See Last Slide for ‘Natural Gas Well Types’) Vertical wells have an average spacing of 40 acres per well, single wells per pad, estimated: 1,475 wells vertical wells: 2-3 acres per well, estimated 3,687 acres disturbance. (using 2.5 acre avg.) Horizontal wells have an average spacing of 640 acres per well, multiple wells per pad, estimated: 92 well Multi-well horizontal pads: 4-6 acres per pad, estimated 461 acres disturbance (using 5 acres avg.) Source: NY State Draft Supplemental EIS: Chapter 5 Natural Gas Development Activities and High Volume Hydraulic Fracturing The exploratory wells have been drilled primarily by private companies. The report is from the USGS, based on “previously unpublished organic chemistry data” from “87 samples from 28 drill holes.” This report was published in 2008, Reid and Taylor came out with a new map in 2010 reviewing the information from the Sanford and sub-basin and the Deep River Basin, but it is not available online.

6 States Take the Lead Limited federal role due to executive and congressional actions Industry prefers state regulation State experience with conventional oil & gas development predates national environmental laws Interstate Oil & Gas Compact Commission -- STRONGER

7 Shale Gas Production Well Pad and Road Construction Drilling
Hydraulic Fracturing Production/ Partial Well Pad Reclamation Re-Fracturing/ Well Closure This slide depicts activities associated with development. Producing shale gas is an industrial process.

8 Well Pad and Road Construction
Time: 7 – 28 Days (Bradford County, PA) Lease the mineral rights Choose a location 3 – 5 acres Determine restricted areas Obtain appropriate permits Follow state and local setback requirements Construct well pad Engineer well pad and roads Plan for chemical and waste storage onsite /prevent spills and leaks Control sediment and erosion Manage stormwater Horizontal drilling generally requires a larger well pad than vertical drilling. This also may extend the time for some of these steps. Mostly, the multi-well pads are drilled and fractured several times so the middle steps (drilling and fracturing) multiply over several times before reclaiming part of the well pad. Thompson Bros, “Nexen Well Pad 9111 and Access Road.”

9 Drilling Drilling, either vertical or horizontal
Time: 21-24 Days (Chesapeake Energy) Drilling, either vertical or horizontal Construct casing for groundwater protection Store drill cuttings Granberg, A “Anatomy of a Gas Well”

10 Hydraulic Fracturing Withdraw freshwater
Time: 2 – 5 Days 40 – 100 Hrs (Pumping) Withdraw freshwater Transport chemicals and proppants to site Mix and inject high pressure solution into the well Collect, store and dispose of flowback water and wastes New York Department of Environmental Conservation, 2009 “Draft Supplemental Generic Environmental Impact Statement on the Oil, Gas and Solution Mining Regulatory Program, Chapter 5”

11 Partial Well Pad Reclamation
Production/ Partial Well Pad Reclamation Time: 7-10 years (Harper, 2010) Produce gas Process gas to remove water Compress and pipe gas to processing plants Collect and dispose of produced water and wastes Reduce the size of the well pad Remove well equipment Close pits and tanks storing waste fluids Reclaim a portion of the well pad Veil, J “Water Management Technologies Used by Marcellus Shale Gas Producers”

12 Re-Fracturing/ Well Closure
Well re-fracturing 7-10 years after initial hydraulic fracturing Impacts similar to original fracturing Well Plugging Plug well to prevent gas releases, surface contamination, and groundwater contamination Restore site Well re-fracturing would require similar amounts of equipment, water and chemicals as the initial fracturing process. https://docs.google.com/viewer?a=v&pid=gmail&attid=0.1&thid=12e d6eb&mt=application/pdf&url=https://mail.google.com/mail/?ui%3D2%26ik%3D0f95c11480%26view%3Datt%26th%3D12e d6eb%26attid%3D0.1%26disp%3Dsafe%26realattid%3D289e aefeb_0.1%26zw&sig=AHIEtbRXCf_jQNWHGnpKm2N0RYutsbdUHQ Source: Harper, J. and Kostelnik, J. “The Marcellus Shale Play in Pennsylvania.” ref: Dewitt, 2008.

13 Cost Estimates for Production
Well Costs in the Millions Royalties Finding and Development Cost (per Mcfe) Haynesville $7.20 25% $1.48 Marcellus $4.50 15% $1.26 Barnett $2.80 $1.41 Fayetteville $3.10 17% $1.50 Colony Granite Wash $6.25 20% $1.37 TX PH Granite Wash $1.18 Average $4.71 The finding and development costs cover exploration. I am unclear whether these well costs cover production costs. The royalties are paid to the mineral rights owner, whether private or the state. Mcfe = million cubic feet IOC = International oil companies. Several of the shale gas producers are being acquired by international oil companies (ExxonMobil and StatOilHydro). Chesapeake sold 32.5% stock to StatOilHydro, and XTO energy was bought by ExxonMobil. Kulkarni, P “Arrival of IOCs and increasing legislative interest signal critical mass for Marcellus” ref.

30 Selected State Responses to Hydraulic Fracturing
Colorado 2009 – House Bill 1292 regulates hydraulic fracturing impacts. Ohio 2010 – Senate Bill 165 Amendments made to many of Ohio’s oil and gas regulations to include provisions for hydraulic fracturing. Pennsylvania July Changes to well casing and cementing rules to prevent blowouts and contamination. June 2010 – Limits for total dissolved solids, barium, strontium, chloride and sulfate in wastewater. Nov Changes to erosion and sediment control plans for sites greater than 5 acres. Wyoming June 2010 – Updates oil and gas regulations to require identification of hydraulic fracturing chemicals Amendments also include handling of well stimulation fluids The industry has developed rapidly. States have struggled to keep up, but States have taken the lead in regulating hydraulic fracturing. Most states with shale gas resources have existing oil and gas industries and expertise with oil and gas exploration & development.

31 Alabama Arkansas Louisiana Texas New York
2000 – Extensive changes to oil and gas regulation, partly to regulate hydraulic fracturing in coal bed methane wells. 2007 – Passed the rule Hydraulic Fracturing of Coal Beds Arkansas Added rule B-19 “Requirements for Well Completion Utilizing Fracture Stimulation” 2010 – Moritorium on injection disposal, extended and expanded in Jan 2011 Louisiana 2009 – Order No. U-HS laid out rules regarding urban development of Haynesville Shale 2009 – Oil and Gas amendment encouraging the reuse of flowback and produced water Texas 2001 – Fort Worth sets city ordinances regarding natural gas production in the city area. New York Generic Environmental Impact Statement on Oil and Gas Solution Mining Regulatory Program Revised Draft Supplemental Generic Environmental Impact Statement in 2010 2011 Maryland General Assembly is debating a moratorium on fracking and a study.

32 North Carolina Law Oil & Gas Conservation Act of 1945
Permits vertical drilling Prohibits horizontal drilling Establishes Permit $50/well $5000/well $0.005/mcf (1000 cubic feet) Article 27, NC GS Permit fees, bonding, and private & state royalties in other states are much higher. State regulation of oil & gas development in most states is receipt supported. Most NC counties levy higher permit fees for domestic wells than $50.

33 Policy Options Study economic and environmental advantages and disadvantages of developing shale gas in North Carolina USGS/NCGS Resource Assessment, Spring 2011 Learn from other States, the industry, EPA, and the public States are primary regulators of this industry Develop a comprehensive regulatory program/avoid inefficient, fragmented regulatory program

34 Policy Options 2010 UNC-CH-Duke Water Allocation Study recommended a moratorium on water withdrawals for shale gas until the Division of Water Resources completes hydrologic models for the appropriate river basins to ensure that water withdrawals will not adversely impact other water users Collect baseline data before development

35 Resources for States State Review of Oil and Gas Environmental Regulations (STRONGER): Hydraulic Fracturing Guidelines, 2010 America Petroleum Institute (API) releases : Hydraulic Fracturing Operations - Well Construction and Integrity Guideline, 2009 Water Management Associated with Hydraulic Fracturing, 2010 Practices for Mitigating Surface Impacts Associated with Hydraulic Fracturing, 2011 US Environmental Protection Agency (EPA) Potential Impacts of Hydraulic Fracturing on Drinking Water Resources – due 2012 State Review (STRONGER) was formed in 1999 to strengthen state regulation of hydraulic fracturing. The process started in 1988 between the EPA and Interstate Oil and Gas Compact Commission (IOGCC). In 1998 the EPA decided to continue to exempt oil and gas production waste from federal regulation, but worked to strengthen state oil and gas regulation. EPA has recently started a study. Funding was set aside in the 2010 fiscal year. The draft of the EPA study plan was released in February EPA’s study takes a cradle to the grave approach to water use during hydraulic fracturing, but is limited to ‘the relationship between hydraulic fracturing and drinking water resources.’ EPA plans to finish its study in 2012.

38 Federal Statues: Clean Water Act CERCLA
Prevents discharges of oil and gas waste to waters of the US with a permit CERCLA Holds drilling companies accountable for all non-petroleum or natural gas pollution on site Hazardous Materials Transport Act and Hazardous Materials Transportation Uniform Safety Act Regulates the transport of hazardous fracturing chemicals to the site Endangered Species Act Functions when working on federal land Would you like a second slide showing federal exemptions? Yes

39 Local Land Use Issues Restricting well development in scenic areas
Requiring stormwater management plans Requiring erosion control plans Setting well spacing requirements Mandating setbacks Residences Water bodies Road ways Setting Noise and Light Standards: Setting hours of operation in urban areas State policy goals could include: protection of public health and the environment, safe development of the resource, increasing the use of cleaner fuels for heating, power generation and transportation, and protection of the property rights of neighboring property owners Comprehensive regulation could include: collection of baseline data before drilling, water withdrawal permit, wastewater discharge permit, well construction permit, including identification of nearby wells and closing abandoned wells, sediment & erosion control permit, stormwater permit, waste management permit, air pollution permit, spill response plan, truck traffic, road construction, training for drillers, financial assurance, etc.

40 Water Quality Issues: AR, CO, LA, OH, PA, WY
Pit and Tank Storage Set standards for construction Ensure compatible fluid or volatile compound containment Spill Prevention* Require spill prevention and containment pollution plans Identify chemicals used in hydraulic fracturing Well casing and cementing Identify and test surrounding water wells before and after fracturing* Require reporting of well casing and cementing logs * Not required in all States

41 Water Quantity and Disposal Water Management Plans: Ex: Delaware River Basin Commission
Fresh Water Report Obtain water use permit Identify sources Create Invasive Species Control Plan Submit hydrologic report (groundwater) Obey Pass-by flow guidelines Record volumes delivered Identify water conservation efforts Waste Water Storage Store only in enclosed tanks Test for chemical constituents Waste Water Report Obtain waste disposal permit from approved facility Address all wastewater produced on site Record produced wastewater volumes Record locations and volumes of disposal

42 Hydraulic Fracturing Reporting
STRONGER Recommendations: Identification of contaminate migration pathways Several states require identification and pre-testing of surrounding wells Reporting should be required before and after hydraulic fracturing operations Notification should allow time for state oversight of operations Reporting should include Identification of the materials used Aggregate volumes of fracturing fluids Proppant used Continuous logs of fracture pressures

43 Areas for Regulatory Consideration:
Truck Traffic Consideration Air Quality Emissions Gas Production Diesel Equipment Usage Fugitive Emissions Chemical Transport Considerations Leasing Issues

44 Multiple Horizontal Well Pad
Well Types: Horizontal Well Spacing: 640 Acres Disturb: 3-5 Acres Vertical Well Spacing: 40 Acres Disturb: 2-3 Acres Multiple Horizontal Well Pad Spacing: 640 Acres Disturbance: 4-6 acres Well Spacing Information from: Source: NY State Draft Supplemental EIS: Chapter 5 Natural Gas Development Activities and High Volume Hydraulic Fracturing DOE National Energy Technology Laboratory “Modern Shale Gas Development in the United States: A Primer” StatOilHydro, “Multiple Well Pad Illustration”
