2. CBM Produced Water in the Rocky Mountain Region • More than 3 billion barrels of produced water in 2000 • Wyoming = 1,901,087,161 (63% of total produced water) • New Mexico = 593,053,102 • Colorado = 250,986,180 • Utah = 145,213,852 • Montana = 113,365,939 • *Based on 2000 Production Data, 42 gallons/bbl

6. CBM Product Water Disposal Costs • Conservative disposal costs = $0.01 - $0.04/bbl • High range disposal costs = $2.00/bbl • Injection costs = $0.20/bbl *Estimates of disposal costs are based on a survey conducted by BC Technologies, Ltd (Laramie, Wyoming) of oil and gas leasees in the Powder River, San Jaun, Raton and Greater Green River Basin.
