A drill site is prepared, a rig is moved in and drilling begins
-Sometimes offered $100,000 to drill on lands of homeowners

Drilling continues vertically thousands of feet below the surface to the kickoff point. From there, the curved and horizontal sections are drilled laterally thousands of feet into the target formation

6
In a controlled operation, a specialized mixture of water, sand and chemical additives are injected into the wellbore at sufficient pressure to create small cracks or fractures in the shale
7
Typically, the multistage hydraulic fracturing process is completed over a 2 to 5 day period. After the well is completed and the surface facilities are installed, the well is placed on production for 20-30 years. Portions of the well site not needed for production are restored.

WHAT IS SHALE?Shale- Black, low-density, organic-
rich rock formed millions of years ago, located thousands of feet below Earth’s surface
Natural gas formed during shale decomposition is trapped in tiny crevices in the shale

ENVIRONMENTAL IMPACTS
EarthquakesAir PollutionLand UseWater UseChemicals
Environmental and Health Effects
16
AIR POLLUTIONThe process of Hydraulic
fracturing causes various chemicals and pollutants to be released into the air
Comes from:The wellThe trucksOpen Air impoundments
17
LAND USE4-6 Acres are necessary per well
3-5 years, possibly even longer
Land becomes restricted access even parks or public land

WATER USE AND POLLUTION 1-5 million gallons of water is needed
per Frack Infused with chemicals 10-20% of water injected comes back up Waste water treatment plants are ill
equipped Produced Water Open Impoundments Spills
1,600 violations in Pennsylvania
Well water contamination

GOVERNMENTAL POLICYSara Tenison
23
GOVERNMENTAL POLICY HISTORY Government policies have influenced the
natural gas industry from the get go Prices of natural gas were unregulated
until the 50s.Became regulated so that companies that
owned the wells and the pipelines could not charge unfair prices
The 1973 Congress passed the Powerplant and Industrial Fuel Use Act of 1978 discouraged the use of natural gas in favor of
coal and renewable fuelsArab oil embargo heightened Congress’ fear of
low oil and gas supplies
24
GOVERNMENTAL POLICY HISTORY Congress passed the Natural Gas Policy Act
of 1978 (NGPA) Relaxed federal price controls intended the NGPA to create a national natural
gas market and to allow market forces to determine wellhead prices (supply and demand, etc.)
Drilling, production and piping increased Prices of natural gas increased
25
GOVERNMENTAL POLICY HISTORY Pipelines and drilling eventually became less
regulated Allowing for smaller businesses to crop up Increased competition Decreased prices No more “bundles”
Fewer monopolies of large companies
NATURAL GAS IN TEXASSara Tenison
27
28
USE OF NATURAL GAS IN TEXASThe most common source of energy in the state
Used in fleet vehicles and busses Reduced 2005 fiscal consumption
of gasoline in Texas by 5 million gallons
29
PRODUCTION OF NATURAL GAS IN TEXAS• Costs of drilling horizontal wells are around 50
percent higher than that for vertical wells. However, the daily production is three to five times higher• In 1993, the chairman of Oryx Energy Co.
• Gas in shale or coal beds were previously considered unrecoverable or uneconomic– The rise in gas prices has encouraged exploration– Only when natural gas prices are high is it worth
drilling through these sources to harvest the gas.– Drilling in these areas is expected to increase
• Texas is nation’s leading producer of natural gas– In 2006, produced 27.8 percent of total U.S.
production

31
BARNETT SHALE It's a vast rock formation
underlies 5,000 square miles surrounding Fort Worth.
Barnett Shale field is the second-largest natural gas field in the continental U.S.
To date there are more than 12,000 gas wells in the Barnett Shale
32
BARNETT SHALE CONTINUED
In the past decade the number of gas compressors in the Barnett has jumped from a few hundred to 1,300
-To get the gas to market requires an underground highway of pipelines and compression stations. These big internal combustion engines make noise and put pollutants into the air -They're getting closer and closer to populated areas
33
TEXAS POLICY In Texas, the U.S. Environmental Protection
Agency (EPA) has delegated most of its authority over major federal environmental laws to the Texas Commission on Environmental Quality. Such as its power over the Clean Air Act
The major exception is oil and gas exploration and production the Railroad Commission of Texas (RRC) has the
EPA’s authority to deal with these matters
34
TEXAS POLICY CONTINUEDThe companies have the right under
federal law to condemn privately owned land to build the project.
This law covers pipeline companies who receive FERC approval for a project but;Are unable to negotiate passage or price
with the private landownersLandowners must be fairly
compensated This practice is largely avoided where
possible because of the potential for dispute
35
TEXAS FRACKING POLICY Outside of regular federal policy, Texas has
not added very much legislation to regulate fracking
Was one of the first two states to require companies to disclose a list of chemicals used Still does not require disclosure of proprietary
The state also has required groundwater data at thousands of wells
36
LOCAL PROBLEMS In order to avoid drying up sources of water,
most of the water drawn from any water source is returned to where it was gotten bad because it is polluted by the time it gets
back Complaints of stomach issues, nausea and
vomiting DISH, Texas
37
DISH, TEXAS
2sq miles, 150 thousand people 10 massive gas lines carry a billion cubic
feet per day through the town the pipelines shoot the gas to the air
settles in one of the subdivisions the people in that subdivision thought
they were going to die local complaints of headaches, diarrhea, nosebleeds,
dizziness, muscle spasms and other problems
As a result, DISH conducted its own air quality test at a cost of 15 percent of the town's annual
budget revealed a toxic mixture of air pollution
38
DISH, TEXAS the air from that area had lots of benzene,
naphthalene, disulfides, was at 55 times benzene health standards and 105 times disulfide standards (Gasland)
the town petitioned and won the right to install permanent air monitorsone of seven in the entire state of Texas.
cancer and neurotoxins will show effect over a long time of exposure (FracAction)
The mayor just recently moved out of the town, wishing to remove his sons from the poisonous air.Media calls him “overdramatic”
39
TEXAS OUTLOOK US demand for natural gas is expected to
keep increasing Very few epidemiological studies have been
done to link complaints and fracking. Individuals “smell things that don’t make them
feel well, but we know nothing about cause-and-effect relationships in these cases”
Some local governments are researching means by which they can drill on existing public land (e.g., parks and cities)
40
MANUFACTURING UNCERTAINTY
Tobacco Companies used to deny smoking was bad with these same techniques
ExxonMobil waged the most successful global warming denial campaign since the Big Tobacco Companies (sunnysuffolk) Admitted in 2007: Used information laundering
used seemingly independent front groups to wagepublic relations for the company.
Funneled about $16 million to these front groups to manufacture this uncertainty.
Paid scientists to cherry-pick data and misrepresent peer-reviewed scientific evidence
Raised doubt and shifted the focus away from global warming action by questioning if the data was "sound science".
Used its extraordinary access to the Bush Administration to block regulation and shape governmental communications about global warming.
The question must be raised: Is this happening again?
POLICY IN OHIOGeetika Srivastava
42
UNCLEAR Relatively new Ohio Not as many well sites compared to
other states Policies ambiguous and unclear as to
whose responsibility it is Major regulators: ODNR and EPA

UTICA SHALE AND MARCELLUS SHALE
45
OHIO DEPARTMENT OF NATURAL RESOURCES Drilling Production Reclamation Brine Disposal Salt Solution Mining Underground Injection Well-Monitoring Issuing permits Setting designs Wastewater Management
46
RECENT ADDITIONSNotifications from companiesEnsuring casing is properly placed as permitted
Testing of blow-out prevention devices
Monitoring of handling of fluid
47
Does not set guidelines for private property leasing
No mention how often these checks and regulations are required
No mention of reviews
48
ENVIRONMENTAL PROTECTION AGENCY Requires companies to obtain
authorization for drilling near bodies of water
Permits needed to install units for activities that emit air pollutants
Proper containment devices and waste management
49
NEW REVISIONS New permit – more general to deal with
inconsistencies in standards from well to well
Emissions limit Operating restrictions Monitoring, testing, and reporting News to be heard on Nov. 28th
50
HOWEVER Emissions include:
Internal combustion engines Dehydration systems Truck-loading racks Storage tanks Flares Unpaved roadways
Does not include emissions from actual drilling and fracturing Considered temporary and exempt from air
pollution regulations
51
ALSO Do not have policies or regulations on
leases between private owners and businesses
Do not state how often regulations and requirements must be met
NEW YORK FRACKING

WHERE IS THE MARCELLUS SHALE?
Extends throughout 5 states: New York, Pennsylvania, Ohio, West Virginia, and Maryland
54
MARCELLUS SHALE IN NEW YORK
55
MARCELLUS SHALE IN NEW YORK First well drilled in 1821 Over 75,000 wells drilled from 1821-
present Approximately 14,000 wells are still
active In 2008 New York imported 95% of its
natural gas from the southwest, but this dependence is quickly decreasing
56
FRACKING NOT WELCOME New York divided
into 17 watersheds Fracking only
requires 0.24% increase in water supply
Delaware River Watershed provides water to 15.6 million people from: Trenton, Philadelphia, Southern New Jersey, New York City
57
DELAWARE RIVER BASIN COMMISSION (DRBC)
Current debate on whether to allow fracking in Delaware River Basin
20,000 gas wells can be drilled in Basin Natural Gas Development Regulations
currently being formed with top priority to protect the water resources of the Basin during construction and operation of fracking projects
58
IN CONCLUSION In conclusion, there is no denying that
natural gas is extremely useful and beneficial to our economy and to our lives.
However, there is a need for a new, safer, way to harvest the natural gas.
Hydraulic fracturing is not the answer to our energy needs. It is, instead, a nightmare to those citizens who are around it.
