Water Use at Extraction Well Pads

The estimated volumes to be used at the well sites during the drilling phase are on average about 1,500 bbls per well. A barrel equals 42 gallons, so an average of 63,000 gallons of water per well during drilling. For the Completion phase, specific to hydraulic stimulation current water volume usage at Interchange B is roughly 25 acre-ft of water per well.  Coil tubing clean-out and tubing installation are expected to utilize about 3,000 bbls per well. The frac designs for the remaining well sites are still being reviewed. Once the remaining water volume estimates are determined the information will be available to the City.

The source or sources of water to be used at the well site during the drilling phase originate from municipal water supplies outside of Broomfield. During the completions phase, which includes hydraulic fracturing,  a variety of water sources may be utilized. Water specific to hydraulic stimulation is drawn from an incorporated mutual ditch and reservoir company. Water specific to coil tubing and tubing install operations is comprised of a mix of ditch, and municipal water supplies originating outside of Broomfield.

Consistent with Section 42 of Exhibit B to the Operator Agreement, Extraction complies with all applicable State of Colorado, Department of Natural Resources and other applicable State regulations concerning the source(s) of water used in the Drilling and Completions phases. Additionally, Extraction is required to provide the Colorado State Engineer with detailed accounting and reporting of their water use.

The water delivered to Extraction is legally allowed for industrial use, has been vetted through the Colorado Division of Water Resources as administrator of water rights in Colorado, and is measured, accounted and reported to both the mutual ditch and reservoir company and Division of Water Resources. Extraction indicates that the capacity of the water conveyance structures exceeds Extraction’s demand by a significant margin.
