Emergency oil reserves: the distance to the pump
Depots, tankers and filling-station inventories: follow fuel after its release. France’s 2022 disruption puts the 2026 announcements in perspective.
“Emergency fuel reserves and the delivery test”, part 3 of 7. Sources checked through 3 October 2026.
On 10 October 2022, representatives of France’s road hauliers met government officials. The ministry reported that an emergency stock release had been decided. It also described operators being mobilised to increase imports, including by sea and from Belgium or Rouen, alongside announced measures to make tanker transport more flexible. The ministry’s statement described measures whose effects would emerge progressively. The supply problem extended across several parts of the network. S09
Four years later, on 2 October 2026, the G7 announced the coordinated implementation of a 100-million-barrel release over four months, with a substantial diesel release frontloaded within the first twenty days; the statement does not quantify the diesel volume. The announcement implements the March commitments while taking account of those already fulfilled. That is a timetable for releasing stocks. It leaves the arrival date at each customer’s premises unresolved. S01
The first instalment examined what the reserves contain, and the second who owns them. This one follows the journey. Fuel can be authorised for release and available at a depot while remaining unavailable at a filling station. Understanding that interval requires a view of the facilities dispatching it, the vehicles carrying it and the retail tanks being drawn down as deliveries resume.
A same-day transfer still leaves a journey
SAGESS, which owns a large share of France’s emergency stocks, says on its website that administrative transfers ordered by the state generally take place within the day. The page is undated. This describes SAGESS’s reported responsiveness in making stocks available; it does not provide measured delivery times to customers. S03
A parliamentary hearing on 8 April 2026 makes the distinction tangible. SAGESS management described making specified volumes available to distributors at designated locations following administrative approval. The distributor gains access to fuel where it is held. The commercial delivery process continues downstream. S05
What remains to be done depends on that starting point. Fuel already held in a depot serving the affected area may enter local distribution directly. A more distant stock needs an additional transport leg. Crude oil still requires refining, as the first instalment explained. The ministry’s account of the supply chain separates bulk movements, mainly by pipeline, barge and rail, from final deliveries to filling stations by road tanker. S06
A reserve can eliminate an entire supply leg. Holding usable product near demand before a disruption is valuable for precisely that reason. A release may also let a distributor draw on stock at a facility it already uses. Portraying every intervention as a convoy setting out from an isolated national warehouse would obscure this advantage of the French system.
The useful question is therefore where in the chain the fuel becomes available. A tonne at a marine terminal, a refinery or a distribution depot has a different remaining journey. Quantities can be compared after harmonising product definitions and units. Their speed of use also depends on their position in the network.
Location is decided before the emergency
SAGESS’s 2025 annual report, published on 11 June 2026, describes 80 storage sites, covering refineries, depots and salt caverns. It states that these are third-party facilities. The figure identifies the storage network described in the report; it does not count independent supply routes into every area of the country. S04 S16
There is an explicit framework behind their location. The French Energy Code requires the board of the CPSSP, the body responsible for the pooled portion of stockholding obligations, to draw up a location plan for stocks under its authority, approved by ministerial order. In its June 2022 review, the International Energy Agency described the aim of making reserves readily available to centres of consumption. S08 S07
This involves an economic trade-off. Concentrating stocks spreads fixed equipment costs over more fuel. Distributing them places some of the buffer nearer users and creates more local options. The value of that spread then depends on connections between facilities. Two depots reached through the same route or served by the same transport resources may share a constraint. This is a network-design observation, rather than a finding about a particular facility’s vulnerability.
The relevant distance is the usable journey. A nearby depot may be poorly suited to the requirement on a particular day. A more distant one may have both the right product and available transport. Comparing the options would require product specifications, genuinely accessible volumes and dispatch slots. The public documents reviewed explain the framework without disclosing those operating parameters for each day of a disruption.
Maps require the same care. A capacity map shows where fuel could be stored. An inventory records what is there. A dispatch programme describes how much can leave during a given period. The three are complementary. Substituting one for another would exaggerate the system’s delivery capability.
At the depot, the constraint is a flow rate
A storage tank answers “how much is left?” A loading point answers “how much can be dispatched today?” One is measured in volume, the other in volume per unit of time. Increasing available inventory extends the period over which distribution can continue. Increasing the speed of distribution requires the rest of the operation to keep up.
A delivery needs access to the product, suitable specifications, collection and receipt to line up. SAGESS’s annual report describes the contractual duty to preserve quantity and quality. Dangerous-goods rules impose their own requirements on the vehicles and operations used to move that fuel. S04 S13
Those requirements also involve people. Training appropriate to the work performed is required for staff involved in transport, loading and unloading. An otherwise available truck does not automatically represent additional fuel-delivery capacity. S14
Consider a haulier switching from its regular loading point to a more distant depot, without attaching any invented operating figures to the example. The alternative may unlock fuel that was previously out of reach. But each round trip may keep a truck and driver occupied for longer. With the fleet and working time held constant, a longer cycle permits fewer cycles. An upstream improvement in access can therefore consume some downstream distribution capacity.
This is why extra volume and extra logistics need to be assessed together. A well-supplied depot may be waiting for collections; available trucks may be waiting for fuel. Useful capacity appears when the two meet. Without operating data, the mechanism can be explained, but no single link can be identified as the nationwide bottleneck on a particular date.
October 2022: intervention along the chain
The decisions taken in autumn 2022 show the categories of constraint the authorities were trying to ease. The 10 October statement combined a stock-release decision, mobilisation of operators to increase imports and announced transport flexibility. These levers affected available product, inflows to the network and movement within it. S09
On 14 October, the ministry extended measures covering weekend circulation and driving times. On 20 October, it announced another extension, including five additional days of driving-time flexibility. The sequence shows that transport arrangements remained part of the response during the recovery described by officials. S10 S11 The publication chronology is available as CSV.
These are official announcements and descriptions of intervention. Their publication dates do not measure the journey time of a consignment. Facilities, ordinary deliveries and purchasing behaviour could all have changed between the statements. Measuring a particular tanker’s journey would require its own loading and receipt timestamps.
The episode is useful because the response addressed several constraints together. Released stocks could compensate for missing supply. Wider operating windows could allow more deliveries. Priority destinations could direct available resources towards selected users. These are different expected effects, even when they serve a common supply objective.
The historical setting also matters. The 2022 statements describe disruption associated in particular with industrial action in the oil sector. They are used here to examine logistics, rather than to describe the causes or severity of conditions in October 2026. S09
Availability at the pump is a separate measure
On 21 October 2022, the ministry published a snapshot of three motorway networks. The proportion of service areas supplied with petrol ranged from 82% to 90%. For diesel, it ranged from 88% to 92%. All six observations appear in the figure. S12
The measure concerns retail locations, separately for each fuel. It says nothing about litres delivered, tank levels or how long an area could keep selling. The statement gives network sizes for VINCI and APRR-AREA but omits SANEF-SAPN’s denominator. The three populations are therefore kept separate. The six observations are available as CSV.
This snapshot illustrates an important feature of recovery: improving supply can coexist with local unavailability. Petrol may be available where diesel is missing, or the reverse. A single measure pooling all fuels would conceal a distinction that matters to the driver who needs a particular product.
The same statement announced priority service for the main holiday routes and the mobilisation of military tankers. It records how the authorities intended to address allocation and transport. It does not establish how many deliveries those reinforcements subsequently made. S12
Priority determines how scarce capacity is allocated. With total resources unchanged, supplying one group sooner may alter another group’s wait. An effective transport reinforcement can instead expand total capacity. Evaluation needs to distinguish changes in who receives deliveries from an increase in deliveries overall.
Refilling tanks while customers empty them
Even after the first trucks arrive, rebuilding a comfortable local buffer requires deliveries to exceed sales. The reasoning follows a tank’s physical balance: over the same period, for the same product, and ignoring losses and measurement adjustments, inventory increases by the volume received less the volume sold.
When incoming fuel exactly matches sales, the tank stops being drawn down. Its buffer nevertheless remains as low as it was at the start. Rebuilding that buffer requires a sustained excess of receipts over outflows. The additional volume stays in the station’s tank, improving its ability to absorb a demand spike or a delayed delivery.
That balance helps explain a fragile recovery. A resupplied station can serve customers again while remaining close to its next stockout. A temporary surge in purchases uses some of the surplus that would otherwise refill the tank. More evenly spaced purchases can allow that surplus to accumulate instead. These effects follow from the inventory balance; this investigation does not quantify their contribution to the 2022 episode.
At national level, another distinction becomes important. A fall in emergency stocks can coincide with a rise in commercial or retail inventories, or with direct consumption. Understanding the destination of the fuel requires tracking transfers between those compartments. A withdrawal from the national reserve alone reveals neither the buffer rebuilt at filling stations nor the service provided to their customers.
The appropriate reporting frequency depends on the question. National endurance calls for a view of remaining accessible stocks. Local recovery calls for receipts, sales and stockout information. Even a daily series can conceal a station that sold fuel in the morning and ran out in the afternoon. Results need to retain their measurement frequency.
Flexibility has to be assessed over time
Sharing facilities between emergency stockholding and commercial operations provides flexibility. In its June 2022 assessment, the IEA described emergency stocks as generally commingled with commercial inventories, with separately held cavern stocks among the exceptions. Using existing infrastructure connects the buffer to the ordinary distribution system. S07
The agency also identified a downside. Very thin commercial inventory margins could lead operators to rely too frequently on emergency reserves, turning them partly into a collective operating buffer. At the same time, it recognised the rapid-response capability of a system well understood by its participants. Its assessment therefore combined an operational advantage with a question about the boundary between private precaution and collective support. S07
A more recent document qualifies any attempt to carry that diagnosis forward unchanged. In the statement covering 2025, SAGESS’s chair described a low level of release instructions, associated with the absence of a crisis affecting economic activity. He also reported technical purchases and sales linked to portfolio adjustments. This is the company’s own account, and the passage does not quantify the frequency. S04
The evidence thus consists of an older institutional assessment and a later description by the operator. Establishing the actual trend would require comparable records of instructions, reasons and volumes. The public material reviewed does not establish that the frequency described in 2022 persisted through 2026.
The missing link in public data
The government fuel-price portal provides a feed containing stockout records, including start dates, end dates where entered and the type of interruption. It also documents closures and fuels that are not distributed. Those states need to be distinguished before unavailability is counted. S15
The published schema does not connect a station to an emergency allocation, a tanker loading or a delivered volume. A price-update timestamp concerns a price. Treating it as the arrival time of a fuel truck would manufacture precision. S15
Measuring the full journey would require linking identifiable operations across authorisation, availability, collection and receipt. Results could then be aggregated by region and product, retaining different routes and the spread of delivery times. Such reporting could be published without disclosing exact stock locations or protective arrangements at individual facilities.
Useful traceability would concern allocated rights and quantities. When products of the same specification share a tank, looking for a particular “strategic molecule” adds little: movement records would be the way to follow the operation. This investigation has not obtained such a linked dataset. It therefore offers no national average time from a release decision to final delivery.
The documents do establish the essential mechanism. Nearby stocks can shorten the supply journey. Loading and transport capacity determine how quickly they can be distributed. Deliveries in excess of sales rebuild the local buffer. The 2022 case shows interventions addressing these different dimensions, with supply still uneven when the motorway snapshot was published.
Present conditions require their own assessment. On 29 September 2026, the European Commission described EU supply as still stable, despite high diesel and jet-fuel prices. On 2 October, it again described EU diesel supplies as stable for the time being, while noting high prices. These dated EU assessments do not establish availability at individual French filling stations on 3 October. Establishing a generalised shortage would require supply data for the relevant area and date. S02 S17
The next instalment moves one step upstream, to the refinery. Where the required product is scarce, nearby crude stocks still leave questions about processing, available throughput and the fuels the facilities can actually produce.

Scope and method
This investigation uses public documents, attributed statements and an explanation of the underlying logistics. The 2022 observations are historical; storage information from the 2025 annual report retains that reference period. Qualitative diagrams and the tank balance are teaching tools, with no invented journey times or volumes presented as measured data. No interviews, field audit or matching of individual deliveries was undertaken. The references above provide access to the evidence used.
