  8. 8. Introduction Presentation GuideOrganization & Flow Standard Slides Integral Advisors US Upstream Almanac is a comprehensive Introduction Slide analysis of drilling and permitting data, providing key insights that Key information oil & gas professionals find useful Top producers and permitters The Almanac is organized in order of increased detail, beginning Well & permit activity map with the Continental United States, followed by Regions, and ending with Basins. Integral worked with our data provider HPDI, LLC (www.hpdi.com) to parse production and permitting data out into 54 specific basins, Vintaged Rate & Well Additions which Integral has further grouped in 12 regions Production and well additions by year since 2001 There are two key data sets in the Almanac: Data parsed by gas, oil and total Historical Activity: Historical production and well additions are equivalent broken out by oil and gas, and top operators are ranked over the last twelve month ("LTM") time period Future Activity: Permitting activity is broken out by operator Quarterly Permits and targeted formation Top formations permitted over last 5 years Continental United States Shown quarterly on graph, with annual data below Regions (12) (Rockies, Alaska, Offshore GoM, etc.) Tabular Data Basins (54) Top producers and permitters shown (Green River, DJ, for last twelve months ("LTM") Sacramento, etc.) U.S. Upstream Almanac January 2011 8
