Shale-Gas in the Appalachian Basin • Extremely Large Resource • 1.6 TCF in 2002 500-1,300 Tcf, today • Large Area – 16-32 Million Acres in the Core Area • Adjacent to the Market • Challenges • Terrain • Infrastructure • Public Perception-Tension / Regulations • History • 1821, Fredonia, New York • 2003 Well - Range Resources • Approximately 6,933 Wells • Pennsylvania - 4,168 • West Virginia – 2,744 • New York – 21 Wells Located in downtown Fredonia, the boulder proudly displays the site of the first commercial gas well in the US, dedicated in 1925 on the 100th anniversary by the Daughters of the American Revolution.

Marcellus Shale • Organic-Rich Marcellus Deposited at Edge of Onondaga Shelf • Low detrital input • High Productivity • Low Removal/Degradation • Relatively Shallow Depths • The areas of high organic content are identified by their relation to the underlying structure at the time of deposition and not by the gross unit thickness of the shale • Local thick areas located in Onondaga thins (Boyce, 2010; Yanni, 2010)

Shale-Gas in West Virginia • Increased Production – Increased Consumption • 500 Bcf/year to 5,000 Bcf/year • Approximately 20% of US Consumption • Heavy Drilling Activity Will Persist for a Decade • Infrastructure Demands • Roads, Housing, Pipelines, Downstream Activities • Tension with the Public Will Decrease • Economic Activity Will Increase • Tax Revenue Will Accelerate • Severance $60 million in 2010 to $240 million in 2020 • Property Taxes – Wells, Transportation, Processing • Example - Johnson Co., Texas $0 in 1998 to ~$64.5 million in 2008 • $16.5 Million County, $12.4 Million Cities, $35.6 Million Schools • Induced Taxes Will Accelerate • Wells Will Persist for 50+ years, but will Production will Decrease.
