Once again the number crunchers at the U.S. Energy Information Administration overestimated natural gas production in the Marcellus/Utica in the agency’s monthly Drilling Productivity Report (DPR). This is a pattern. Perhaps making such revisions is inevitable, but we find it disconcerting. Last month the EIA predicted total production in the Marcellus/Utica region (which they call Appalachia in the report) would be 35.67 billion cubic feet per day (Bcf/d). In the monthly DPR issued yesterday, EIA revised the June number down to 35.16 Bcf/d. Not a huge difference. It translates to 515 million cubic feet per day (MMcf/d) less in production--roughly 1/2 Bcf/d.
