FracTracker Looks at Water and Chemical Usage in Ohio Shale Drilling



From FracTracker:
Our Ohio intern and I have been working to compile complete water and chemical usage data for Ohio’s horizontal Utica wells. At this point we have an inventory for 248 wells and thought it would be helpful to present our initial analysis.

Water Use

Million gallons per fracked well interval range for 248 horizontal Utica wells.

The Ohio Utica wells are using 4.4-4.6 million gallons (±1.6 MG) of water per fracked well1 (Fig. 1). On the low end of the range are the 93,402-533,412 gallons for the Onega Commissioners 14-25H (PDC Energy), Kernich 3-10-2 1H, and Starkey 36-13-4 5H wells in Guernsey, Columbiana, and Carroll Counties, respectively; the latter two are owned by Chesapeake Energy. On the high end are the four 10 MG+ Antero and Anadarko wells in the counties of Monroe, Muskingum, Noble, and Coshocton (Fig. 2).
Excluding Carroll County – where this water usage is equivalent to 63% of the county’s per capita annual water usage – the Utica wells have used 1.2 billion gallons of water or 3.2% of the population’s annual water demands2. When the state’s additional permitted wells come online they will require an additional 2.5 billion gallons of freshwater…
