Global Outlook for Oil and Natural Gas

1. Global Outlook for Oil and Natural Gas IPAA Annual Meeting November 7, 2007 Houston, TX Jeff Dietert Managing Director, Research Simmons & Company International

2. Limited supply visibility. Potential for higher prices: Growing challenges for non-OPEC supply. Diminishing IOC access via asset nationalization. Increasing government rent. Aging work force and infrastructure. Cost escalation & service company constraints. Limited data available to assess future outlook for supply. Healthy non-OECD demand. Rising call on OPEC crude & uncertain spare capacity. Weak US dollar. Risks that could negatively impact prices: Weak OECD demand. Uncertain US economic outlook. Mild winter weather outlook. Oil Macro Outlook

3. Historical Oil Demand Growth • Demand has been slowed by oil price spikes and recessionary periods. • Non-OECD oil demand has been more resilient and pronounced than the OECD. OECD and non-OECD Oil Demand, 1960-2005

4. Oil Demand Growth Focused in the Non-OECD • Per capital consumption in the developing world is a fraction of the OECD average. • Non-OECD demand has grown at ~3% pa (~1.2 mb/d), despite higher oil prices. Per Capita Oil Consumption Demand Growth Segmentation

5. Non-OPEC Oil Supply • We expect non-OPEC supply to be flat in 2008 and down in 2009-2010, putting substantial pressure on OPEC supply growth to meet non-OECD demand growth. Non-OPEC Supply Growth Stalls After 2007

8. Limited OPEC Spare Capacity • Effective spare capacity is 2.66mb/d (per IEA), only ~3% of global demand. • Little information is available to assess the deliverability of the spare capacity. • The major is low quality crude in Saudi Arabia, vs. demand for light sweet crude. • Risks to physical disruptions have increased.

9. Natural Gas Macro Outlook Above-average supply visibility in 2007/2008. Tight market 2010+. Factors that could drive prices higher: • Increasing demand pull from Asia. • Uncertain outlook for Russian natural gas supply. • Growing power generation demand. • Declining Canadian production. Risks that could negatively impact prices: • Growing U.S production, aided by Independence Hub & Rockies Express. • Increasing LNG liquefaction & regasification capacity. • Mild winter weather outlook. • Declining industrial demand. • Relatively high storage levels and growing storage capacity.

11. Natural Gas Supply Visibility  A large number of major supply projects provide visibility for late 2007 & 2008 global supply growth. ***LNG Liquefaction Additions: over 4 bcfd in both 2008 and 2009. ***Texas Production Growth: +1.8 bcfd y/y. ***Independence Hub/GOM: +0.8 bcfd to 1bcfd by YE'07.   ***BP/Atlantis/GOM: +0.2 bcfd by YE'07.  ***Rockies Express Pipeline: +1.5 bcfd of capacity by Jan'08. ***Orman Lange/Norway: Initial production Oct'2007, increasing to over 2 bcfd in 2009. Major Contributors to Supply Growth Y/Y

13. Russian Supply: Critical to Europe Russia Natural Gas Exports

14. Growing Domestic Production • GOM production has been flat m/m since October 2006. Independence Hub should add ~ 1.0 bcfd by YE07. • Texas production growth is accelerating (primary Barnet Shale), currently +1.8 bcfd y/y. • Wyoming production has been pipeline capacity constrained since October 2006. Rockies Express will add 1.5 bcfd of pipeline capacity starting Jan 2008. Reported Production Statistics

17. Natural Gas DemandSecular Growth in Power Generation Incremental Net Generation Y/Y • Natural gas fired generation has supplied 64% of incremental electricity since 2000. • Natural gas fired generation capacity is underutilized, while coal and nuclear generation is running at near full capacity. • Gas demand in the power sector has grown at ~1 bcfd and over the last three years.
