US oil prices settled over $100 for the first time in 16 weeks; diesel prices at an all time high; production of crude from US wells at a record high; total US oil supplies lowest since March 1984 with the Strategic Petroleum Reserve the lowest since November 1982; oil refined was the most one week in seven years, refinery utilization rate was 2nd highest in eight years..
US oil prices rose for a fifth time in six weeks after the US “destroyed” at least eight Iranian oil tankers in the Persian Gulf and Gulf of Oman, Houthi attacks on Saudi oil facilities forced them to shut down, and Iran fired advanced missiles at U.S. warships in a new escalation of the war…after rising 9.7% to $91.48 a barrel last week after the US launched a new wave of attacks on Iranian infrastructure and shipping and Iran retaliated against US bases and allies in the region and their shipping, the contract price for the benchmark US light sweet crude for October delivery edged higher in early Asian trading on Monday after U.S. forces struck three Iranian crude carriers following Iranian missile attacks aimed at two U.S. warships, and traded at a six-week high, while Brent, the international benchmark, settled 1.1% higher after Iran vowed to strike energy infrastructure across the Middle East in response to further U.S. attacks on its assets, further escalating a conflict that had sharply reduced oil supply from the region…oil prices surged nearly 3% during Asian trading hours on Tuesday after Yemen’s Houthis attacked energy facilities in Saudi Arabia, while Iran threatened the US with what it called “economic warfare,” increasing fears that the war would disrupt more oil supplies from the region, and touched a 13-week high in early trading in New York after fresh Houthi attacks on Saudi energy facilities forced their operations to shutdown , and settled $1.55 higher at $93.03 a barrel after the Houthi attacks on Saudi energy facilities set oil installations ablaze and threatened a major expansion of the Middle East war…oil prices climbed more than two percent across Asia on Wednesday, as escalating US-Iran tensions continued to roil global energy markets, then extended their rally Wednesday morning in New York, as the recent escalations in the U.S.-Iran war stoked further supply fears, and settled $3.02 higher at $96.05 a barrel after U.S. forces struck five Iranian oil tankers and Iran targeted a U.S. base in Jordan and attacked 10 ships…oil prices extended their gains in early global trading on Thursday after Iran said it had attacked 10 ships near the Strait of Hormuz, putting the spotlight back on the Strait and its role in global energy supplies, but traded slightly lower in London on Thursday morning on profit-taking after the strong price rise the previous day, then rallied to top $100 for the first time since May in early New York trading after the EIA reported the US Strategic Petroleum Reserve was near a record low and Cushing stocks were just off ‘tank bottoms’ and contined to ralliy to settle $6.43 higher at $102.48 a barrel for an eighth straight gain, the longest streak higher in more than three years, following the news that the Iran-aligned Houthis had seized control of Yemen’s port of Mocha on the Bab el-Mandab Strait, further increasing their threat to oil flows through the Red Sea….oil prices extended their climb during early Asian trading on Friday, reaching their highest since May, as hostilities in the Gulf continued and the prospect of peace seemed even more remote, but retreated during morning trading in New York as reports that Iran was in negotiations with Gulf states to establish a jointly managed shipping route through the Strait of Hormuz weighed on prices, and settled $2.43 lower at $100.05 a barrel, reversing early gains after the Financial Times reported that foreign ministers in the Middle East were trying to work out a temporary deal with Iran to manage shipping through the Strait of Hormuz, but still finished 9.4% higher for the week, settling above $100 for the first time in over four months…
meanwhile, natural gas prices finished lower for the first time in five weeks as traders shifted their focus to the Autumn “shoulder season”, when little demand for either cooling or heating is expected….after rising 3% to $2.975 per mmBTU last week on lower production, higher LNG demand, and forecasts for record cooling demand in September, the price of the benchmark natural gas contract for October delivery opened 2 cents lower on Monday and gradually arced lower through the morning, as traders focused on the impending shoulder season and fading cooling demand, and settled 5.9 cents lower at $2.916 per mmBTU, as electric power demand dropped sharply and fading cooling demand outweighed strong LNG feedgas needs….natural gas prices opened 6.3 cents lower on Wednesday, tumbling overnight as shoulder season conditions took hold, and settled 9.4 cents lower at $2.822 per mmBTU as fading power demand and the approach of milder fall temperatures pressured the market, despite strong LNG feedgas demand and expectations for a relatively lean storage report Thursday…natural gas prices started Thursday 4.8 cents lower, moving down overnight as traders looked to easing demand as the season moves deeper into September, then dropped to an intraday low of $2.753 as a bearish storage report hit the wire, before posting a steady recovery in the following hours to settle 1.2 cents higher at $2.834 per mmBTU, supported by lower production and strong LNG feedgas demand, despite fading weather-driven demand and a larger-than-expected storage build…natural gas futures showed little sign of recovery on Friday morning, as traders assessed a bearish storage surprise and seasonal declines in power sector demand, and continued to slump through morning trading, weighed down by seasonally strong production readings and forecasts for waning weather demand, and settled 0.3 cents lower at $2.831 per mmBTU, and thus ended 4.8% lower for the week as rapidly fading power sector demand and the approaching shoulder season outweighed strong LNG feedgas and lower production.
The EIA’s natural gas storage report for the week ending September 4th indicated that the amount of working natural gas held in underground storage rose by 40 billion cubic feet to 3,254 billion cubic feet by the end of the week, which left our natural gas supplies 76 billion cubic feet, or 2.4% below the 3,333 billion cubic feet of gas that were in storage on September 4th of last year, but 148 billion cubic feet, or 5.2% above the five-year average of 3,106 billion cubic feet of natural gas that had typically been in working storage as of the 4th of September over the most recent five years….the 40 billion cubic foot injection into natural gas storage for the cited week was more than the 35 billion cubic foot injection into storage that the market had been expecting ahead of the report, but it was less than the 69 billion cubic foot of gas that were injected into natural gas storage during the corresponding week of 2025, and also less than the average 52 billion cubic foot injection into natural gas storage that had been typical for the first week in September over the past five years…
The Latest US Oil Supply and Disposition Data from the EIA
US oil data from the US Energy Information Administration for the week ending September 4th showed that despite a big drop in our oil exports, we had we had to pull oil out of our stored crude supplies for the nineteenth time in twenty weeks, and for the 41st time in sixty-seven weeks, in part due to another increase in demand for oil the EIA could not account for…. Our imports of crude oil rose by an average of 53,000 barrels per day to 6,824,000 barrels per day, after rising by an average of 612,000 barrels per day during the prior week, while our exports of crude oil fell by an average of 1,066,000 barrels per day to average 3,417,000 barrels per day, which, when used to offset our imports, meant that the net of our trade of oil worked out to an import average of 3,407,000 barrels of oil per day during the week ending September 4th, an average of 1,119,000 more barrels per day than the net of our imports minus our exports during the prior week… At the same time, transfers to our oil supplies from Alaskan gas liquids, from natural gasoline, from condensate, and from unfinished oils were unchanged from the prior week at 887,000 barrels per day, while during the same week, production of crude from US wells was 85,000 barrels per day higher at a record high of 13,947,000 barrels per day. Hence, our daily supply of oil from the net of our international trade in oil, from transfers, and from domestic well production appears to have averaged a total of 18,241,000 barrels per day during the September 4th reporting week…
Meanwhile, US oil refineries reported they were processing an average of 17,586,000 barrels of crude per day during the week ending September 4th, an average of 91,000 more barrels per day than the amount of oil that our refineries reported they were processing during the prior week, and the most we’ve refined in one week in seven years, while over the same period, the EIA’s surveys indicated that a total of 233,000 barrels of oil per day were being pulled from the supplies of oil stored in the US… So, based on all that reported & estimated data, the crude oil figures provided by the EIA appear to indicate that our total working supply of oil from storage, from net imports, from transfers, and from oilfield production during the week ending September 4th averaged a rounded 888,000 more barrels per day than what our oil refineries reported they used during the week. To account for the difference between the apparent supply of oil and the apparent disposition of it, the EIA just plugged a [ -888,000 ] barrel per day figure onto line 16 of the weekly U.S. Petroleum Balance Sheet, in order to make the reported data for the supply of oil and for the consumption of it balance out, a fudge factor that they label in their footnotes as “unaccounted for crude oil”, thus indicating there must have been a error or omission of that amount in the week’s oil supply & demand figures that we have just transcribed…. Since 623,000 barrels per day of demand for could not be accounted for in the prior week’s EIA data, that means there was a 265,000 barrel per day difference between this week’s oil balance sheet error and the EIA’s crude oil balance sheet error from a week ago, and hence the changes to supply and demand from that week to this one that are indicated by this week’s report are somehow off by that much, and therefore not very useful… However, since most oil traders react to the figures in these weekly EIA reports as if they were gospel, and since these weekly figures therefore often drive oil pricing and hence decisions to drill or complete oil wells, we’ll continue to report this data just as it’s published, and just as it’s watched & believed to be reasonably reliable by most everyone in the industry…(for more on how this weekly oil data is gathered, and the possible reasons for that “unaccounted for” oil supply, see this EIA explainer….also see this March 2023 twitter thread from an EIA administrator addressing these ongoing weekly errors, and what they had once hoped to do about it).
This week’s rounded 233,000 barrel per day average decrease in our overall crude oil inventories came as an average of 56,000 barrels per day were being pulled out of our commercial stocks of crude oil, while 178,000 barrels per day were being pulled out of our Strategic Petroleum Reserve, the twenty-fourth consecutive Iran war related withdrawal from the SPR, including the four largest draws in SPR history, which left the SPR level at 285,360,000 barrels, the lowest since it was initially being filled in November 1982….with both commercial oil and the SPR both down again this week, that left the Total of all US Oil Supplies at 709,429,000 barrels, down 18.5% from 870,774,000 barrels on April 17th, and the lowest since March 30th, 1984….
Further details from the weekly Petroleum Status Report (pdf) indicated that the 4 week average of our oil imports fell to 6,586,000 barrels per day last week, which was still 2.3% more than the 6,436,000 barrel per day average that we were importing over the same four-week period last year, while the four week average of our exports rose to 3,940,000 barrels per day last week, which was 6.4% more than the 3,703,000 barrel per day average that we were exporting last year year at this time… This week’s crude oil production was reported to be 85,000 barrels per day higher at all time high of 13,947,000 barrels per day as the EIA’s estimate of the output from wells in the lower 48 states was 71,000 barrels per day higher at 13,490,000 barrels per day, while Alaska’s oil production was 14,000 barrels per day higher at 457,000 barrels per day…US crude oil production had reached a pre-pandemic high of 13,100,000 barrels per day during the week ending March 13th 2020, so this week’s reported oil production figure was 6.5% higher than that of our pre-pandemic production peak, and was also 43.8% above the pandemic low of 9,700,000 barrels per day that US oil production had fallen to during the third week of February of 2021.
US oil refineries were operating at 97.8% of their capacity while processing those 17,586,000 barrels of crude per day during the week ending September 4th, down from 98.0% the prior week, but still the second highest refinery utilization rate in eight years ….the 17,586,000 barrels of oil per day that were refined that week were the most we’ve refined in one week since August 16th, 2019, 4.6% more than the 16,818,000 barrels of crude that were being processed daily during the week ending September 5th of 2025, and 0.5% more than the 17,495,000 barrels that were being refined during the pre-pandemic week ending September 6th, 2019, when our refinery utilization rate was at 96.4%, which was close to the pre-pandemic normal utilization rate for this time of year…
Even with the increase in the amount of oil that was being refined this week, gasoline output from our refineries was somewhat lower, decreasing by 587,000 barrels per day to 9,308,000 barrels per day during the week ending September 4th, after our refineries’ gasoline output had increased by 73,000 barrels per day during the prior week… This week’s gasoline production was 2.9% lower than the 9,587,000 barrels of gasoline that were being produced daily over the week ending September 5th of last year, and 10.2% less than the gasoline production of 10,360,000 barrels per day seen during the prepandemic week ending September 6th, 2019….on the other hand, our refineries’ production of distillate fuels (diesel fuel and heat oil) increased by 222,000 barrels per day to 5,348,000 barrels per day, after our distillates output had decreased by 9,000 barrels per day during the prior week. After that big production increase, our distillates output was 2.3% more than the 5,229,000 barrels of distillates that were being produced daily during the week ending September 5th of 2025, and 0.1% more than the 5,341,000 barrels of distillates that were being produced daily during the pre-pandemic week ending September 6th, 2019….
Even with this week’s decrease in our gasoline production, our supplies of gasoline in storage at the end of the week rose for the sixth time in thirty weeks, increasing by 1,269,000 barrels to 206,938,000 barrels during the week ending September 4th, after our gasoline inventories had decreased by 1,173,000 barrels to a 42 week low during the prior week. Our gasoline supplies rose this week because the amount of gasoline supplied to US users fell by 371,000 barrels per day to 8,551,000 barrels per day, and because our imports of gasoline rose by 94,000 barrels per day to 464,000 barrels per day, and because our exports of gasoline fell by 62,000 barrels per day to 872,000 barrels per day… After fifty-four gasoline inventory withdrawals over the past eighty-one weeks, our gasoline supplies were 5.9% lower than last September 5th’s gasoline inventories of 219,997,000 barrels, and about 5% below the five year average of our gasoline supplies for this time of year…
After this week’s big increase in distillates production, our supplies of distillates rose for the seventeenth time in thirty weeks, increasing by 2,087,000 barrels to 106,274,000 barrels during the week ending September 4th, after our distillates supplies had increased by 796,000 barrels during the prior week… Our distillates supplies rose by more this week even though the amount of distillates supplied to US markets, an indicator of domestic demand, rose by 288,000 barrels per day to 3,678,000 barrels per day, because our exports of distillates fell by 179,000 barrels per day to 1,556,000 barrels per day, and because our imports of distillates rose by 72,000 barrels per day to 185,000 barrels per day… After 28 withdrawals from distillates inventories over the past 60 weeks, our distillates supplies at the end of the week were 11.9% lower than the 20,638,000 barrels of distillates that we had in storage on September 5th of 2025, and were about 13% below the five year average of our distillates inventories for this time of the year…
Finally, even after the big drop in our oil exports, our commercial supplies of crude oil in storage fell for the 14th time in twenty-six weeks, and for the 26th time over the past year, decreasing by 391,000 barrels over the week, from 424,460,000 barrels on August 28th to 424,069,000 barrels on September 4th, after our commercial crude supplies had decreased by 4,450,000 barrels over the prior week….After this week’s decrease, our commercial crude oil inventories were back to the recent five-year average of commercial oil supplies for this time of year, while they were still about 28% above the average of our available crude oil stocks as of the first weekend of September over the 5 years at the beginning of the past decade, with the difference between those comparisons arising because it wasn’t until early 2015 that our oil inventories had first topped 400 million barrels. After our commercial crude oil inventories had jumped to record highs during the Covid lockdowns in the Spring of 2020, then jumped again after February 2021’s winter storm Uri froze off US Gulf Coast refining, but then fell sharply due to increased exports to Europe following the onset of the Ukraine war, only to jump again following the Christmas 2022 refinery freeze-offs, changes in our commercial crude inventories had been less extreme up until the onset of the Iran war, when they were initially built up to a three year high by mid-April, before falling to the lowest in nearly eight years by late July…This week’s decrease was the second in six weeks, and as of September 4th our commercial crude inventories were 0.1% below the 424,646,000 barrels of oil we had in commercial storage on September 5th of 2025, but were 1.2% more than the 419,143,000 barrels of oil that we had in storage on September 6th of 2024, and 0.8% more than the 420,592,000 barrels of oil we had left in commercial storage on September 8th of 2023…
This Week’s Rig Count
The US rig count increased by three over the week ending September 11th, as the number of rigs targeting oil was up by one, the count of rigs targeting natural gas was up by two, and miscellaneous rigs were unchanged…for a quick snapshot of this week’s rig count, we are again including below a screenshot of the rig count summary table from Baker Hughes…in the table below, the first column shows the active rig count as of September 11th, the second column shows the change in the number of working rigs between last week’s count (September 4th) and this week’s (September 11th) count, the third column shows last week’s September 4th active rig count, the 4th column shows the change between the number of rigs running on Friday and the number running on the Friday of the same week of a year ago, and the 5th column shows the number of rigs that were drilling at the end of that reporting period a year ago, which in this week’s case was Friday, the 12th of September, 2025…
