8. -8--8- A Popular Topic, but No Clear Public Consensus “We’re draining our reserves dry.” “Enough oil to last for 500 years.” Houston Chronicle May 30, 2004 Llewellyn King Chairman & CEO King Publishing Co. Publisher for: White House Weekly & Energy Daily Houston Chronicle May 30, 2004 H. Sterling Burnett Senior Fellow National Center for Policy Analysis

16. -16--16-

17. OK Greg, if it is that simple, why is it so hard to drive a consensus on the subject? Economic theories (and realities) are simple, but the inner workings of the oil industry are very complex.

18. How Complicated is the U.S. Crude Oil Industry? You be the judge.

19. -19--19- Oil Imports 9.6 Domestic Production 5.7 Oil Exports.001 Stocks & Net Loss/Gain (0.1) Refined Products ImportsExports 2.6 1.0 Other Liquids 0.1 NGPL Direct Use & Blends 0.7 Residential 0.8 Commercial & Industrial 5.2 Transportation 13.3 Electric Power 0.5 Crude Oil Refinery Input 15.3 NGPL Refinery Input 0.4 Other Liquids 0.9 Total Refinery Input 16.6 Processing Gain 1.0 Output 17.6 Aggregate Output Mogas 44% Distillate 20% LPG10% Jet 8% Resid 4% Other 14% The U.S. Demand Side of The Equation Volumes Approximate 2003 Daily Average (MMBLS) (1) (1) Source: EIA; BP; GLA estimates

20. -20--20- Additional Complicating Factors Affecting Supply, Demand & Product Slate l l Changes in natural gas frac spreads affect availability of blendstock and raw products l l Seasonality (changing feedstock demands) l l Weather l l Transportation & scheduling logistics l l Competing fuels (natural gas, coal, etc.) l l Restrictions on product specifications l l Product imports/exports l l Multiple varieties of crude l l Metals content l l Emmission issues l l Scheduled/Unscheduled downtime l l Etc., etc., etc.

21. -21--21- Additional Complicating Factors Affecting Supply, Demand & Product Slate l l Changes in natural gas frac spreads affect availability of blendstock and raw products l l Seasonality (changing feedstock demands) l l Weather l l Transportation & scheduling logistics l l Competing fuels (natural gas, coal, etc.) l l Restrictions on product specifications l l Product imports/exports l l Multiple varieties of crude l l Metals content l l Emmission issues l l Scheduled/Unscheduled downtime l l Etc., etc., etc. Two areas of Focus.

22. -22--22- Getting 9.6 mmb/d of Oil to The U.S. Source: BP

24. -24--24- U.S. Pipeline Infrastructure Designed to Displace Crude to Meet PADD II Demand Inter-PADD Movements Driven Primarily by Economics of: Transportation differentials Quality issues (inter- grade surplus/shortage & refinery constraints)

28. -28--28- Variations in Selected Domestic Differentials to WTI

29. -29--29- Variations in Selected Canadian Differentials to WTI

30. -30--30- Example of an Impending Complication: Storm Clouds Forming or Light Shower? Situation: A.U.S. market is currently balanced with foreign waterborne imports. B.Canada is projected to ramp up oil sands production ~500,000 b/d+ C.U.S. GOM is projected to ramp up deepwater production ~500,000 b/d+ D.U.S. demand is not projected to simultaneously grow by 1 million b/d. E.Mideast Politcs are highly unstable.

31. -31--31- Possible Outcomes: 1. The U.S. begins exporting over 500,000 b/d. 2. U.S. producers shut-in over 500,000 b/d or reduce drilling activities (at ~ $40.00/bo) to make room for incremental volumes. 3. Foreign sources of waterborne imports happily withdraw 500,000 b/d from the market (thus losing market share in the world’s most critical market?). 4. Inventories begin to build; price pressure hits the U.S. market and competition among grades and qualities intensifies. 5. Something unexpected happens to balance the market (strike, Mideast disturbance, explosion in demand, etc.) 6. Some combination of all of the foregoing Example of an Impending Complication: Storm Clouds Forming or Light Shower? Continued.

32. Oil Industry Prediction (Challenge): “We are going to be living in interesting times.” Chinese Proverb (Curse): “May you live in interesting times.”

33. -33--33- GLA View is that both statements are correct, “We’re draining our reserves dry.” Houston Chronicle May 30, 2004 Llewellyn King Chairman & CEO King Publishing Co. Publisher for: White House Weekly & Energy Daily “Enough oil to last for 500 years.” Houston Chronicle May 30, 2004 H.

34. Not any time soon… …,but it could get REAL expensive. Is the U.S. Running Out of Oil? World
