Natural Gas Report
In this week's EIA report there was a 66 BCF injection to storage raising the volume of working gas in storage to 2,542 BCF as of the 23rd.
Over the next 19 weeks injections need only average 42.3 BCF / week to match the highest weekly storage number of 3,327 BCF established in 2004. Despite the relatively low injections the last four weeks a normal air conditioning load this summer will still result in record high storage levels by fall and continued downward pressure on prices. To put the 42.3 BCF per week in context during the injection season (April-October) of 2005 there were only 7 weeks when net storage injections were less than 42.3. In 2004 there were only 4 weeks.
In a higher than normal storage situation early in the injection season consumers that store gas for winter see that they are ahead of schedule and may slow purchases hoping that prices will decline. Spot or uncommitted storage being in short supply may increase in price. Producers might want to reduce production hoping for better prices later. Some production may be curtailed because higher pipeline pressures slow the flow of gas from the wells. Fuel switching from fuel oils has increased demand for power generation. A combination of these factors and some additional demand induced by lower prices explain why injections have been below average for the last six weeks.
We will address some of these issues in an update and extension of the natural gas series next week.
For the week of June 23, 2006 there was a 66 BCF injection to storage compared to an average injection of 103 BCF for the closest weeks in the previous 5-year period. Current storage at 2,542 BCF is 618 BCF (32.1%) above the 5-year average and 409 BCF (19.2%) above last year. For the reporting week natural gas spot prices averaged $6.493 / mmbtu and crude oil was $69.93 per barrel ($12.057 / mmbtu). So far this week spot gas averaged $5.972 / mmbtu and crude oil was $71.97 per barrel ($12.409 / mmbtu).
With spot prices at $5.97 and January futures at $10.38 more than one person has considered buying spot gas for storage and selling a January contract for the same volume on the futures market. This has put upward pressure on storage prices.
Population weighted cooling degree days totaled 71 which was 16 degree days greater than average and 20 more than last year. At 2 heating degree days, for the reporting week of the 23rd, gas consumption weighted heating degree days were 4 less than normal and 1 less than last year. (See population weighted cooling degree days at cooling degree days, gas home heating customer weighted degree days at heating degree days and the NOAA temperature anomaly map.)
We see continued downward pressure on gas prices relative to crude subject to support from concern about the hurricane season and the mercurial forecasts of warmer weather. Some industrial demand has returned. The latest data is for April with industrial consumption 1.2 BCF per day lower than last year. While lower than last year it indicates a 1.8 BCF per day improvement from the impact of last year's hurricanes on industrial consumption.
Natural gas prices are below the price of residual fuel oil in most markets and power plants and industrial users with dual fuel capability have switched to natural gas. Since liquid prices are higher on a BTU basis than natural gas, producers with liquids in their gas stream remove all that they can. This takes something over a half BCF per day from natural gas supplies compared to last December.
Crude oil prices are a significant component of natural gas prices. Crude oil and natural gas markets overlap where natural gas competes with fuel oil in industrial and power generation facilities with dual fuel capability. Normally the price of natural gas at the Henry Hub is below crude oil at Cushing, OK on a BTU equivalent basis. It only goes above crude when there is concern about meeting winter demand. At the burner tip delivered gas is usually higher than crude but we are using the most common gas price at the Henry Hub in Louisiana which is a long way from most consumers. Gas must incur additional transportation and distribution costs before reaching the customer.
Gas prices have moved back in line with our expectations relative to crude oil. The margin between crude and natural gas spot prices on a BTU basis is at $6.437 up from $5.564 last week. Natural gas so far this week averaged $5.972 and is $0.521 lower than last year. With gas $0.521 per mmbtu lower than a year ago and crude oil up $2.365 per mmbtu ($13.72 / bbl.) the implication is that high storage levels have reduced natural gas prices by $3.559 per mmbtu compared to crude oil prices over the last year. At this point crude oil is a major support for natural gas prices but high gas storage levels continue to exert downward pressure.
Weekly Average Price

Oil $71.97 $69.93 $58.25 $2.04 $13.72
Gas $/mmbtu $5.972 $6.493 $7.166 ($0.521) ($1.194)

Gas-Oil ($6.437) ($5.564) ($2.877) ($0.873) ($3.559)
Higher than normal inventories are the primary reason behind the failure of gas to follow the annual increase in crude. Our outlook is a little more negative for gas prices. We expect the basis between gas and crude oil to widen a little more. However, fear of a recurrence of last year's hurricane damage has already slowed that process.
At a $70 crude oil price $5.50 would be near the lowest spot gas price we would expect with summer hurricane fears supporting prices. On a percentage basis natural gas prices have been lower than crude by more than they are today and given the level of storage and $70 per barrel oil prices with $5.00 gas is a possibility. The open question is how how much support prices get from the hurricane fear factor? We anticipate no more than another $1.00 of downside risk to gas prices if crude oil remains near $70 per barrel.
Storage Data
In the Eastern Consuming region gas in storage is 33.8% above the 5-year average, the Western Region is 24.0% above normal, and the Producing Region is 33.0% above the 5-year average.
Total current storage of 2,542 BCF is 618 BCF (32.1%) above the 5-year average and 409 BCF (19.2%) higher than last year when natural gas spot prices were $1.19 higher at $7.17.
Eastern storage at 1,359 BCF is 343 BCF (33.8%) above the 5-year average and 261 BCF (23.8%) above last year. There was a net injection of 42 BCF, which is 25 BCF less than the five year average of 67 BCF. The East is always the critical area to watch and remains in good shape.
Storage in the Producing Region showed a net injection of 15 BCF compared to a 5-year average injection of 25 BCF. The Producing Region now contains 827 BCF with storage 205 BCF (33.0%) above the 5-year average and 118 BCF (16.6%) above last year.
Storage of 356 BCF in the West Consuming Region is 69 BCF (24.0%) above the 5-year average of 287 BCF and 29 BCF (8.9%) above last year. There was a 9 BCF injection which is 3 BCF less than the 5-year average.
Prices continue to justify high levels of exploration. Gas exploration activity is at historically high levels. See gas rig count.
The Weekly Storage Report has detailed graphs by region.
There are five items that determine natural gas price this summer: (1) crude oil price, (2) actual and forecast temperature, (3) the level of U.S. and Canadian drilling activity, (4) planned and unexpected outages at nuclear power plants, (5) forecast and actual hurricanes and (6) the rate of recovery for Gulf production.
Note: Remember that there is insufficient production, import or pipeline capacity to support winter consumption and that 2.0 - 2.5 TCF must be added to storage each year before the winter heating season begins.

The MMS stopped regular report of Gulf of Mexico status. On June 19 they issued another report. There was 0.935 BCF per day of gs still shut-in compared to 1.295 BCF per day of gas on May 4. Shut-in oil production was 174,970 b/d compared to the previous number of 324,445 b/d. See the Katrina/Rita This has been slow but considerable improvement in the last 6 weeks. The more dramatic oil numbers are due to Thunderhorse coming back on-line. Fortunately there is no short term need for the gas with storage levels near historic highs. See the GOM page for regional detail of damage updates.
The two graphs below are the best short term indicators of natural gas prices.
The first shows the relative prices of natural gas and crude oil with oil prices converted to their BTU equivalent. Since oil and natural gas compete directly in some markets, most notably power generation, high crude oil prices put upward pressure on natural gas prices.
The second shows the difference between the current volume of storage and the 5-year average. When the difference is significantly below normal it is an indicator that demand exceeds supply implying higher than "normal" prices.
The red line in the graph below (scaled on the left) shows the difference between the current level of gas in storage and the average of the previous five years. The black line (scaled on the right) is the current natural gas price less the price of crude after it is converted to the BTU equivalent price.
