6 The Challenge 6 Shale Plays Tight Gas Tight Oil Conventional How can liquid production be enhanced in low permeability formations? Bigger Initial Production and greater Recovery at reduced costs

7 Shale oil characteristics 7 Hydrocarbon liquids found in low permeability formations Shales, siltstones, sandstones and carbonates Resource unlocked by technology application similar to shale gas Horizontal drilling Multi-stage hydraulic fracturing Pad drilling First mover play was the Bakken, in North Dakota Currently at 1 million bbl/d with ~1,000+ wells completed Other plays are fast followers - Eagle Ford, Utica, Niobrara, Permian

8 Development of technology Trial & Error approach Macro Micro Science Nano Science Development of downhole Motors accelerates key to Directional drilling Initial development of Barnett Shale Gas production increases as Technology improves First Commercially Frac ed well in US Gel Fracs Foam Fracs Gas Fracs Multi-well Pads s 1980 s First Frac ed shale gas well Fredonia, New York First commercial Horizontal wells Multi-stage fracturing emerges for both vertical and horizontal wells Liquid Rich Shales Evolution Modified from US Dept of Energy, EIA,
