Inventory & Storage Tracking

Estimating crude oil and refined product volumes held in above-ground storage tanks by measuring floating-roof shadow displacement and tank fill-level geometry from satellite optical imagery.

Governments and national oil companies are flying blind when commercial traders and foreign majors know their strategic reserve levels before they do. Floating-roof storage tanks betray their contents: as volume rises or falls, the roof translates vertically, casting a shadow whose arc length is a precise proxy for ullage. High-resolution optical satellites can resolve that shadow geometry to within a few centimetres of roof displacement, translating directly into a volume estimate accurate to ±3–5% of tank capacity — good enough to detect significant drawdowns or build-ups within a single revisit cycle.

A sovereign constellation changes who controls that intelligence. When a nation rents imagery from a commercial provider, the same data is simultaneously available to commodity desks, hedge funds and foreign intelligence agencies. A nationally operated optical microsatellite system can prioritise tasking over domestic terminal storage, strategic petroleum reserves, and export terminals on a schedule driven by national need rather than commercial queue position. Onboard processing can suppress raw pixel data to ground level and deliver only derived volume estimates, keeping underlying imagery within a classified enclave.

The operational payoff is direct. An energy ministry can cross-reference satellite-derived inventory curves against reported pipeline throughput and customs export manifests to detect unreported stock movements, smuggling, or discrepancies that indicate transfer pricing abuse. The same feed supports macro-economic forecasting, sanctions compliance verification for imported feedstocks, and real-time input to national strategic reserve management — intelligence functions that no commercially purchased data subscription can deliver with the requisite confidentiality and continuity of access.

What matters

A 1 cm change in floating-roof elevation corresponds to roughly 100–300 barrels of crude depending on tank diameter — satellite resolution is already sufficient for economically material volume detection.
Commercial imagery providers sell the same tasking products to commodity traders, meaning a nation's reserve drawdown is market-visible before any policy decision is announced.
Sanctions regimes and export controls can be silently circumvented through unreported inter-tank transfers; only persistent, sovereign-controlled satellite coverage closes that verification gap.
Strategic petroleum reserve levels are classified national security data in most jurisdictions — hosting the inference pipeline on foreign cloud infrastructure is legally and operationally incompatible with that classification.

Sovereignty score: 8/10 — A nation that allows foreign commercial operators to hold primary access to its storage inventory data has effectively outsourced a core instrument of energy policy and economic security to the open market.

Strategic petroleum reserve levels are classified in most jurisdictions under energy security legislation; routing raw imagery or derived volume data through foreign commercial cloud pipelines creates an automatic classification breach.
Commercial satellite operators sell the same storage analytics to commodity trading desks, meaning a sovereign customer's drawdown decisions are visible to currency and futures markets before domestic policymakers can act — a direct threat to energy price sovereignty.
Sanctions enforcement and export control verification require continuous, uninterrupted coverage of domestic terminals; a commercial subscription can be suspended, repriced, or deprioritised under foreign export regulations at precisely the moment geopolitical tensions make the data most critical.
Domestically operated inference pipelines allow volume estimates to be fused with classified pipeline SCADA data and customs manifests, a cross-domain integration that foreign-hosted services cannot legally or technically support.

Reference architecture

Payload: Electro-optical push-broom imager, 0.5–0.75 m GSD panchromatic, 12-bit radiometric depth, 15 km swath; secondary SWIR band (1.6 µm) for haze penetration and heated product differentiation; onboard shadow-geometry extraction FPGA to suppress raw imagery before downlink
Bus class: ESPA-class microsatellite, 120–160 kg, 600 W end-of-life solar array power, 3-axis stabilised to <0.003° pointing knowledge for sub-pixel geometric accuracy
Orbit: Sun-synchronous LEO at 480–520 km, 10:30 local time descending node for consistent shadow geometry, 16-satellite walker constellation providing 12–18 hour revisit over national territory; paired tasking with a SAR auxiliary for cloud-gap fill
Ground segment: Primary X-band downlink station co-located with national oil company headquarters; secondary S-band TT&C at a sovereign military facility; encrypted ground-to-ground fibre backhaul; no commercial ground station network used for classified product tiers
