Water Management Analysis

Following assumptions are based on the information fro www.marcellusgas.org:

Water used to drill a well: 700,000 gallons (16,667 barrels)
Water used to Frack a well: 5,000,000 gallons (119,047 barrels)
   
Wells drilled and Fracked each year: 3,000
Number of wells per pad site: 6
Pad size: 300' x 600' (180,000 sq. ft., or 4.132 acres)
   
Water tanker capacity: 6,720 gallons (160 barrels)
   
Average precipitation: 48 to 54 inches per year
Collection Capacity of D.A. Nolt, Inc. of PA CWMS: 7,000,000 gallons per year
Water cost at source: $0.35 per barrel (42 gallons)

The following table identifies the resulting water usage and potential for fresh water storage based on the assumptions defined above:

This table illustrates that by 2019, fresh water held in our underground water management systems would be sufficient for all subsequent years’ well drilling and fracking operations, consequently eliminating some 2,544,643 tractor trailer trips per year (based on 6 wells per pad). In addition, the Water Management Containment System would provide fresh water for all future stimulation, refracking and operational needs during the life of the well pad.
