2 EIA s mission and main functions Independent Statistical and Analytical agency within the U.S. Department of Energy EIA collects, analyzes, and disseminates independent and impartial energy information to promote sound policymaking, efficient markets, and public understanding of energy and its interaction with the economy and the environment. By law, its data, analyses, and forecasts are independent of approval by any other officer or employee of the U.S. Government [EIA] is the gold standard for energy data around the world, and the accessibility of it is so much greater than other places Dan Yergin, Platts Inside Energy 2

3 Annual Energy Outlook 213 projections to 24 Growth in energy production outstrips consumption growth Crude oil production rises sharply over the next decade Motor gasoline consumption reflects more stringent fuel economy standards The U.S. becomes a net exporter of natural gas in the early 22s U.S. energy-related carbon dioxide emissions remain below their 25 level through 24 3

6 These three drivers impact resource estimation metrics differently over time in an iterative process Theory Experiment Practice Thermal maturity Pressure Formation depth Geology Recompletions Drilling costs Technology Price of gas Economics Resources in Place Technically Recoverable Resources (TRR) Economically Recoverable Resources (ERR) P Q Well-level data, incl. estimated ultimate recovery (EUR) 6

7 EIA s focus is on the timing of production; the modeling focuses on these parameters average initial production (IP) rate per well average decline curve (can vary by region and vintage) IP & decline curve define the Estimated Ultimate Recovery (EUR) per well Other parameters drilling and operating costs number of active rigs how many wells a rig can drill (rig efficiency) well spacing 7
