Gas Oil Liquids Daily North America's Gas, Oil & Liquids News & Market Information Thursday, April 24, 2008 No. 2027 --------------------------------------------------------------------------------Crude Oil Futures Up After EIA Inventory Report Crude oil futures for June delivery on the NYMEX ended $0.23 higher yesterday to settle at $118.30 per barrel, after the EIA released its weekly inventory report. RBOB gasoline rose $0.0343 to settle at $3.0507 per gallon, and May heating oil futures gained $0.0071 to $3.324 per gallon. Crude oil prices reached a record Tuesday when the dollar touched an all-time low of $1.6018 to the euro. Unions planning to strike at a 200,000 bpd refinery in Scotland next week are holding talks with the plant's owners Ineos Group Holdings after failing to reach agreement. The weakness of the dollar is a great driver. Oil has become a monetary phenomenon, where low rates boost demand for oil in emerging markets. Workers are planning to strike at Ineos' Scottish plant, which takes crude from BP Plc's Forties Pipeline System that transfers oil from more than 50 North Sea fields. Oil has also gained because of a supply disruption in Nigeria. Royal Dutch Shell closed 169,000 bpd of supply after attacks on a pipeline last week. The EIA released its weekly report on inventories. Crude oil stocks surged by 2.4 million barrels, double the forecast level, mainly from gains on the West Coast. Gasoline inventories fell for the 6th straight week, by 3.2 million barrels against the forecast for a 2.3 million decline. Lingering geopolitical worries also supported prices. New attacks on Nigeria oil export facilities are likely to partly offset this week's start-up of Saudi Arabia's 500,000 bpd Khursaniyah field. Refinery workers at Britain's Grangemouth refinery are due to begin a 2-day strike on Sunday that will shut the plant and squeeze fuel supplies in Scotland and northern England. In London, Brent crude oil futures for June delivery on ICE gained $0.51 to $116.46 per barrel yesterday. --------------------------------------------------------------------------------- NYMEX: Light Crude Oil Futures Wednesday, April 23, 2008 Month/Yr Jun '08 Jul '08 Aug '08 Sep '08 Oct '08 Nov '08 Dec '08 Jan '09 Feb '09 Mar '09 Apr '09 May '09 Open 117.45 116.61 115.83 116.27 115.75 114.70 114.73 114.20 113.50 113.18 112.76 112.36 High 118.69 117.59 116.89 116.27 115.75 115.24 114.73 114.20 113.67 113.18 112.76 112.36 Low 116.90 116.50 115.75 116.27 115.75 114.70 114.73 114.17 113.50 113.18 112.76 112.36 Last 118.30 117.59 116.89 116.27 115.75 115.24 114.73 114.17 113.67 113.18 112.76 112.36 Chg +0.23 +0.33 +0.38 +0.42 +0.47 +0.48 +0.49 +0.49 +0.49 +0.49 +0.51 +0.53 Volume 225830 38732 14438 7620 2837 1827 15558 217 44 214 52 76 Open Int Chg 369363 -7141 108246 -587 50136 +1723 59490 +226 48128 +323 23740 +128 197521 +1619 27392 -24 12070 +0 12992 +192 9349 +0 17746 +20 $/Barrel -------------------------------------------------------------------------------NYMEX- Light Crude Oil Futures for June NYMEX- Light Crude Oil Futures for June settled higher on Wednesday as it extended this spring's rally into uncharted territory. June crude oil has rallied $20.96 since the March 20th low. Wednesday's high-range close sets the stage for a steady to firmer opening this morning. Studies are showing positive momentum but are now in overbought territory, so some caution is warranted. The market's close above the 9-day moving average suggests the short-term trend remains positive. With the close higher than the pivot swing number, the market is in a slightly bullish posture. If June extends this month's rally into uncharted territory, upside targets will be hard to project. Multiple closes below the 20-day moving average crossing $109.73 would confirm that a shortterm high has been posted. First resistance is Tuesday's high crossing at $118.98. First support is the 10-day moving average crossing at $114.17. Second support is the 20-day moving average crossing at $109.73. -------------------------------------------------------------------------------NYMEX: West Texas Int.

US crude imports are likely to rise because of lower inventories and the strength of local oil prices relative to the rest of the world, Goldman analysts led by Giovanni Serio said in their Energy Weekly report. ‘Looking into the second half of this year, given the fundamental tightness, we believe the risks are substantially skewed to the upside,’ the report said. The bank said on April 10th that oil may not fall as far as it expected previously, predicting that prices may slip to $98.80 in the spring, above a previous floor of $90 per barrel. Crude oil futures rose to a record $119.90 per barrel Tuesday. Goldman maintained its expectations for the price of the front-month crude contract in 3, 6 and 12-months at $102, $107.50 and $115 per barrel respectively. The bank's forecast for the average price in 2008 of $105 is the secondhighest. -------------------------------------------------------------------------------NYMEX: Natural Gas Futures Wednesday, April 23, 2008 03 06 12 18 Month Month Month Month Month/Yr May '08 Jun '08 Jul '08 Aug '08 Sep '08 Oct '08 Nov '08 Dec '08 Jan '09 Feb '09 Mar '09 Apr '09 $/MMBtu Avg..................................................... 10.9370 Avg..................................................... 11.0683 Avg.....................................................11.3076 Avg..................................................... 10.8687 Open 10.470 10.620 10.760 10.825 10.845 10.930 11.220 11.820 11.810 11.780 11.500 9.820 High 10.820 10.955 11.037 11.084 11.164 11.189 11.246 11.511 11.866 12.046 11.751 10.021 Low 10.430 10.595 10.735 10.825 10.845 10.905 11.220 11.820 11.810 11.780 11.500 9.820 +0.1793 +0.1755 +0.1664 +0.1596 Last 10.781 10.946 11.084 11.164 11.189 11.246 11.511 11.866 12.086 12.046 11.751 10.021 Chg +0.174 +0.183 +0.181 +0.174 +0.172 +0.169 +0.169 +0.164 +0.159 +0.154 +0.149 +0.149 Volume 75252 32935 10447 6006 3050 5445 1801 917 2786 924 2211 2419 Open Int 41418 129202 80013 32142 26513 66889 32235 35647 54653 14192 44292 37047 --------------------------------------------------------------------------------- NYMEX- Henry Hub Natural Gas Futures for May NYMEX- Henry Hub Natural Gas Futures for May settled higher on Wednesday as it extended this month's rally above March's high crossing at $10.365.

New refineries including Reliance Industries’ Jamnagar plant and the increased use of ethanol in gasoline could cause refining margins to decline through 2012, Alan Gelder, a consultant for downstream oil at Edinburgh-based Wood Mackenzie, said yesterday at a refining conference in Barcelona. Increased ethanol use in North America means less oil-based gasoline is required, which will lower demand and cut profits for refiners, Gelder said. Slowing economic growth will also lead to less consumption of gasoline, he said. Refining margins, or the profit from turning a barrel of oil into fuels, in the first quarter this year averaged $0.86 per barrel. Refiners using Brent crude in their facilities in northwest Europe may have earned $1.10 per barrel so far this year. Investments in petrochemical production using naphtha crackers should stop because there is ample spare capacity and margins will be weak up to 2010 and beyond, Gelder said. Petrochemicals include ethylene, building blocks for consumer goods like plastics. Reliance will produce propylene, another building block for plastics, using a fluid catalytic cracker, or FCC, at its second refinery in Jamnagar. FCC's are normally used in the production of gasoline. The new refining complex is due for completion by the end of this year, Vikram Sampat, vice-president of the strategic planning department at Reliance said yesterday at the same conference. --------------------------------------------------------------------------------NYMEX: RBOB Gasoline Futures Wednesday, April Month/Yr May Jun Jul Aug Sep Oct Nov Dec Jan Feb Mar Apr '08 '08 '08 '08 '08 '08 '08 '08 '09 '09 '09 '09 23, 2008 Open 3.0192 3.0126 3.0000 2.9651 2.9320 2.8166 2.7956 2.7549 2.7890 2.8189 2.8449 2.9804 High 3.0544 3.0465 3.0336 3.0100 2.9801 2.8459 2.8088 2.7979 2.8022 2.8189 2.8449 2.9804 Low 2.9925 2.9874 2.9750 2.9550 2.9266 2.8130 2.7875 2.7483 2.7832 2.8189 2.8449 2.9804 Last 3.0507 3.0424 3.0294 3.0084 2.9774 2.8459 2.8109 2.7964 2.8024 2.8189 2.8449 2.9804 Chg +0.0343 +0.0323 +0.0293 +0.0278 +0.0258 +0.0238 +0.0223 +0.0203 +0.0193 +0.0193 +0.0193 +0.0193 $/Gallon --------------------------------------------------------------------------------NYMEX- RBOB Gasoline Futures for May NYMEX- RBOB Gasoline Futures for May settled higher on Wednesday as it extended this month's rally into uncharted territory.

Ineos Group Holdings is in talks with its main labor union, which has threatened to strike on April 27 at its Grangemouth refinery over a dispute about pensions. The chemical company has started closing down the 200,000 bpd refinery, supplied by the Forties pipeline, in preparation for the strike. ‘We are making preparations for the eventuality that we need to shut down the Forties Pipeline System if that is required,’ a spokeswoman for BP, said. ‘A total shutdown of the Grangemouth refinery would impact the Forties Pipeline System.’ BP has been talking with Ineos to establish whether the shutdown will halt supplies of steam and electricity at the nearby Kinneil terminal, which are essential services for deliveries of Forties crude, she said. --------------------------------------------------------------------------------NYMEX: Heating Oil Futures Wednesday, April 23, 2008 Month/Yr May '08 Jun '08 Jul '08 Aug '08 Sep '08 Oct '08 Nov '08 Dec '08 Jan '09 Feb '09 Mar '09 Apr '09 Open 3.3240 3.3071 3.3031 3.2926 3.2850 3.3100 3.3121 3.3485 3.3275 3.3288 3.2915 3.2385 High 3.3285 3.3100 3.3127 3.3162 3.3265 3.3393 3.3461 3.3600 3.3559 3.3545 3.3100 3.2525 Low 3.2785 3.2585 3.2645 3.2680 3.2829 3.2941 3.3049 3.3141 3.3275 3.3288 3.2900 3.2378 Last 3.3240 3.3072 3.3112 3.3162 3.3262 3.3367 3.3472 3.3572 3.3627 3.3547 3.3187 3.2602 Chg +0.0071 +0.0100 +0.0130 +0.0140 +0.0135 +0.0130 +0.0135 +0.0140 +0.0145 +0.0160 +0.0180 +0.0200 $/Gallon -------------------------------------------------------------------------------NYMEX- Heating Oil Futures for May NYMEX- Heating Oil Futures for May settled slightly higher on Wednesday as it extended this month's rally into uncharted territory.

Recently, they have been trying to figure out: Has a shift or evolution in market forces led to a ‘decoupling’ of crude oil and natural gas prices in the United States? Proponents of a relationship between crude oil and natural gas prices argue that competitive market forces, especially on the demand side, maintain a relationship between the prices. Oil and natural gas are substitute fuels primarily in the electric generation and industrial sectors. Dual-fired units can burn the less expensive fuel, subject to environmental restrictions. However, potential fuel switching is not limited to dual-fired units. Changes in consumption patterns also occur system-wide based on relative fuel prices, either among units operated by a single company with multiple plants or operated by competitors. The potential to shift consumption based on relative prices would operate to mitigate excessive price differentials between natural gas and oil. The opposing view questions whether the fuel switching that remains today still can affect the market given that the diminishing number of dual-fired units, on a relative if not absolute level, limits fuel competition at the margin. The increasing tendency for monthly crude oil and natural gas prices to diverge supports this argument. A more stable price difference in the 1990s was broken with a few short-lived periods when prices either diverged sharply or tended to converge.
