1 US Ethane Outlook: Implications for US Processors and Ethylene Producers Presented to PFAAs Eleventh Annual Conference Barton Creek Austin, Texas November 3 rd – 5 th, 2004 Peter Fasullo En*Vantage, Inc

2 2 Background: Last December 03, Enterprise commissioned En*Vantage to: 1.Determine the sensitivity of the NGL midstream environment to the business cycles of the US ethylene industry. 2.Assess how the GulfTerra merger changes Enterpises sensitivity to ethylene business cycles and to different price decks for crude and natural gas. Study completed in February 04 and was presented to rating agencies, bankers and security analysts, made public at security analyst meeting on May 26, Challenge was to develop simple bench marks to gauge whether the NGL business environment would improve or worsen. Part 1 of the study primarily centered on the fundamentals driving ethane supply/demand and frac spreads. Today: Walk through methodology and share updated findings regarding the outlook for ethane and its implications.

3 3 Why Ethane? --- It is the one NGL component that has frustrated processors and ethylene producers the most. On average, ethane constitutes 37% of the US NGL barrel extracted, but yields have varied from 34% to 46% when processing economics dictated. Ethane extraction is mostly discretionary and very sensitive to economic conditions, frac margins and location of the processing facility. When extraction economics are good for ethane, they are good for the entire processing operation, and the opposite is true - especially for cryogenic plants. Unlike other NGLs with multiple end uses, virtually all ethane is used in ethylene production, competing with other NGL and petroleum feedstocks. On average, ethane constitutes 45% of the US ethylene feedstock mix and it provides the highest ethylene yield of all the feedstocks. But, history indicates that ethane cracking can swing quickly from 38% to 51% of the mix when feedstock economics dictate or cracker utilization rates change. Overall, ethane supply and demand can easily swing 100 MBPD or more in a market that has averaged around 750 MBPD.

4 4 Ethane is extremely dependent on gas processing and ethylene production. Supply & Demand fundamentals may appear simplistic, but they are complex and volatile. Key market drivers influencing ethane cracking and extraction: Ethane Cracking Ethylene business cycle Cracker capacities & feedstock capabilities Competing feedstocks Ethylene co-products Derivative Imports/Exports Ethane Extraction Frac spreads Processing contracts Plant type Plant location Gas quantity & quality Source: DOE, En*Vantage, Hodson

5 5 Our analysis of ethane supply & demand focused on two primary drivers. Primary DriverRationalInfluence Natural Gas to Crude Price Ratio (Henry Hub Gas/Cushing WTI on a BTU basis) Gas sets price floor for NGLs (ethane) and petroleum derived feedstocks and products set the market price. Processing Margins Feedstock Economics US Ethylene Production as driven by GDP growth US ethylene industry consumes 54% of total NGLs supplied and virtually all of the ethane extracted from natural gas. The amount of ethane consumed should increase as ethylene production increases. Need to determine how co-products can affect ethane cracking. Both being inversely related to the gas to crude price ratio

7 7 NGL frac spreads are inversely correlated to the gas to crude price ratio..... Study Completed Source: Platts & En*Vantage

8 8....and that inverse relationship is reflected in the amount of NGLs extracted versus the gas to crude price ratio. But what causes this particular pattern and variability? Trough Conditions R 2 = 0.63 Source: DOE and En*Vantage

9 9 The pattern and variability seen in NGL extraction versus the gas to crude price ratio is mostly due to the fundamentals driving ethane extraction. Needs further investigation. Trough Conditions Source: DOE and En*Vantage

10 10 Ethane extraction closely tracks ethane cracking, influenced by the gas to crude price ratio. But, how do competing feedstocks & ethylene business cycles affect the amount of ethane cracked?

11 11 The gas to crude price ratio appears to influence the cracking of ethane versus heavy feedstocks. So, how does the absolute level of ethylene production affect ethane cracking?

12 12 For the past 5 years, U.S. ethylene production varied anywhere between 48 and 58 billion lbs/yr rates and it is currently rebounding from the mid-year 2003 trough.

13 13 As ethylene production increases, ethane cracking increases and the flexibility to swing ethane volumes diminishes.

15 15 The shift in US ethylene capacity, the past few years, is estimated to shift the ethane cracking range downwards by about 15 to 20 MBPD.

16 16 Our analysis indicates the following implications for ethane demand at different levels of US ethylene production. Ethylene Production Effective Utilization Ethane Cracking Levels 1 (MBPD) (B Lb/Yr)(%)Min.Max.Flex. RangeTrendline Excludes Refinery Ethane 1.Higher ethylene production requires greater ethane cracking (min and max) and the industrys flexibility to swing ethane volumes diminishes. 2.The gas to crude price ratio also influences ethane cracking levels, particularly when ethylene industry utilization rates are between 80% to 90%. Gas to crude price ratios above 90% increase the probability of minimizing ethane cracking. 3.However, it appears that the US Ethylene Industry can not stay at minimum ethane cracking levels for more than 3 months without creating a surplus of ethylene co-products.

17 So what does the future hold for ethane cracking and extraction?

18 18 Back in February 2004, we felt that conditions in 2004 should provide a better environment for ethane cracking. Ethane Cracking Swings Between MBPD Are Possible with a Bias to Maximize Ethane Cracking High Probability of Ethane Cracking Swings Between MBPD with a Bias to Minimize Ethane Cracking as long as Co- Product Production is Not an Inhibitor At B Lb/yr, Moderate to Good Probability of Ethane Cracking at or above 650 MBPD. Gas to Crude Ratio Less of a Factor at Production Rates above 55 B Lb/yr Gas to Crude Price Ratio Below 90% Above 90% Ethylene Production Below 53 B LB/YRAbove 53 B LB/YR High Probability of Sustainable Ethane Cracking at or Above 650 MBPD

19 19 To support greater ethane cracking levels, the ethane frac spread increases to encourage more ethane extraction. Q3 04 Q1 04 Q2 04 Source: Platts, En*Vantage and Hodson

22 22 US ethane extraction is distributed across the major processing regions. Regional costs of getting ethane to market is determined by T&F fees and gas basis % Rocky Mtn. Mid-Continent Texas Inland Texas Gulf Coast Louisiana Gulf Coast New Mexico Upper Midwest Other 5-Year Average Ethane Regional Production from Processing (MBPD ) 85 12% % 58 9% % 97 14% 20 3% 9 1% % of US Ethane Production US Processing NGLs: 1843 MBPD US Processing Ethane: 682 MBPD US Ethane/US NGLs: 37% Rockies Ethane/NGLs: 40% NM Ethane/NGLs: 47% Tex Inland Ethane/NGLs: 39% Tex GC Ethane/NGLs: 42% La GC Ethane/NGLs: 35% Mid-Cont Ethane/NGLs: 36% 80% of US Gas Production is Processed 590 processing plants - 72 BCFD capacity 56% of plant capacity is cryogenic 70 fractionators million BPD capacity 85 % of Frac capacity at market centers Source: EIA and En*Vantage

23 23 Each processing region responds to economic signals to throttle up or down ethane extraction to meet ethane demand. Analysis of each regions cost of getting ethane to market shows that the Rockies is not always the swing producer. East LA often provides the swing. Source: EIA & En*Vantage Data indicate that the processing industry can ramp up ethane extraction to near 800 MBPD, which supports 62 to 63 billion lb/yr of ethylene production.

24 24 La GC and Rockies will be the incremental producers of ethane in the 05 to 10 time period. Source: DOE, En*Vantage

25 25 Our study demonstrated how ethylene production along with the gas to crude price ratio can determine ethane supply & demand and the amount of swing that can be expected. Ethylene Demand Ethylene Production Feedstock Capabilities Ethane Demand GDP Growth Effective Operating Rate Composition of Plants Gas to Crude Price Ratio Ethane Frac Spread Regional Extraction Economics Regional Ethane Production Ethane to Market Demand Side Factors Supply Side Factors

26 26 In Conclusion: Ethane is very much alive!!! --- barring a recession. As ethylene production grows, ethane cracking must increase and the flexibility to switch off ethane diminishes. Paradigm shift to a tighter crude market will keep ethane competitive with heavier feedstocks. Ethane frac spreads should remain strong to encourage extraction in all regions. This is not the time for processors to retreat from cryogenic plants. Current infrastructure is in place to support ethane extraction in the 750 to 800 MBPD range, which can support ethylene production levels of 60 to 62 billion lbs/year as the economy moderately grows. By 2010, ethane production should reach and sustain the 800 MBPD level, with the Rockies and La Gulf Coast contributing a larger share. Ethylene producers need to closely track the regional shift in ethane supplies.
