National Petroleum Council Reports: Dramatic
Change in Gas Supply
“North American and U.S. natural gas production is
likely to lag projected demand growth over the study
time frame, requiring significant growth in LNG
imports….
Forecasts range from 2.5 percent of U.S. supply to 16
to 18 percent by 2030.”
- National Petroleum Council, 2007
“As a result of drilling technology advances and the
emergence of the recent ‘game changing’ shale gas
plays, the gap between U.S. demand and production
Is closing rapidly and likely to reduce greatly the
future need for LNG imports.”
- National Petroleum Council, 2011

Hydraulic Fracturing
Well Bore Integrity Key to Environmental Protection
Multiple layers of Protection
•Conductor casing is set and
cemented
•Surface Casing is cemented
below deepest aquifer
•Surface casing is cemented
to surface
•Production casing inside
surface casing to formation
•Production casing
cemented back to surface
•Steel production tubing
•Internal plastic coating on
tubing to prevent corrosion

Water Management is Critical for Shale Gas
Development
Phases of water
management for shale gas

● Withdrawal
● Transport
● Storage
● Use (drilling and
fracturing)
● Treatment and
reuse/recycle
● Treatment and disposal

Secretary of Energy Advisory Board
Recommendations
www.shalegas.energy.gov
Manage short-term and cumulative
impacts on communities, land use,
wildlife, and ecologies
Protect water resources
Disclosure of fracturing fluid
composition
Identify research and development
needs
Create a public, national portal
improving public information.
Organize for sharing best practices
Improve communication among
state and federal regulators
Reduce use of diesel fuel in
fracturing
EPA Shale Gas Study
EPA: Study the Potential Impacts of Hydraulic Fracturing on
Drinking Water Resources
•Best available science
•Independent sources of information
•Transparent, peer-reviewed process
•Consultation with others
Next Steps:
•Publish an interim report of results in 2012
•Provide additional results in a 2014 report
Available Resources:
In 2009, DOE and the Ground Water Protection
Council (GWPC) published “Modern Shale Gas
Development in the United States: A Primer,” an indepth analysis of Shale Gas development , including
water management and disposal issues related to
shale gas stimulation and production.
In 2009, DOE helped fund GWPC publishing a
comprehensive review of regulations designed to
protect water resources nationwide. This report,
“State Oil and Natural Gas Regulations Designed to
Protect Water Resources,” includes a detailed look at
current state oil and gas regulations intended to
protect water resources, including regulations
related to hydraulic fracturing and waste handling.

Factors in U.S. Shale Gas Success
Below Ground:
Favorable Geology
Technology – Including U.S.
Government R&D
Infrastructure – pipelines and
domestic industry
Above Ground:
Stabile & Transparent
Regulatory/Taxes/Fiscal Terms
Developed Gas Markets
Ease in Leasing
Factors in Global Shale Gas Development
Additional Factors to those in U.S.:
Access to:
•Resources,
•Gas Treatment,
•Pipelines, and
•Markets
Ability/Willingness to Import
Expertise:
•Investment Climate: Huge
Capital Required
•Equipment
•People (Visa support)
Great Potential, BUT:
In infancy – shale geology not
yet proven
You never know if it is
economic until drilled!!
