Marcellus Shale Drilling In West Virginia Patrick Campbell - May 12, 2009

Marcellus not present west of this line Area of thicker Marcellus

Coalbed methane Marcellus Shale Trenton- Black River Different age rocks of recent interest to oil and gas producers

Number of Marcellus Permits in Last Two Years Approx. 682 (includes vertical and horizontal) 295 Number of Marcellus Wells Drilled in Last Two Years Approx. 427 (includes vertical and horizontal)

Water WaterMuch Larger Volumes For Drilling/ Fracturing Roughly 10 Times More Water

3-6 million gallons needed to Drill & Frac Horiz. Well Source water? What happens to the water? 30-70% of water used flows back. We looked at one well

Guidance noticed March 2009 Additional Site Construction controls Requires additional info via permit addendum Water volume to be used Water source: surface, ground, or purchased (percentage of each and specific location) Water disposal method: UIC, POTW, other Water Use Registration if > 750,000 gallons/ month

INDUSTRY ADVOCACY Supports guidance v. rules Guidance shouldnt say shall and must Allow use of BPJ when determining adequate stream flow TDS did not appear document falls far short Water withdrawals should be permitted Set limits for TDS Regulations on all aspects (cradle to grave) No land application of pit fluids

House Bill A bill that would have required WVDEP to develop specific standards to control TDS Interest remains high, much more to come...

Thanks for your interest!
