Refinery Throughput Estimation

Inferring crude processing rates at domestic and foreign refineries by fusing satellite thermal infrared, optical and SAR observations of operational signatures.

A government that cannot independently measure what its own refineries are processing — or what rival nations' refineries are producing — is flying blind on energy security. Refinery throughput is rarely published in real time, and when it is, the numbers are routinely massaged. Satellite-derived estimates cut through that fog: stack temperatures, floating-roof tank positions, distillation-unit heat signatures and vessel traffic at jetties combine into a proxy throughput figure accurate to within 5–10% of actual crude runs.

The satellite stack required is deliberately multi-modal. Thermal infrared payloads (8–12 µm band) resolve heat plumes from crude distillation units and cokers; optical imagery tracks floating-roof tank positions to estimate inventory draws that imply throughput; X-band SAR provides all-weather, day-night coverage of tankage and vessel loading activity. Fusing these three data streams in a sovereign analytics pipeline produces daily throughput estimates for every refinery of interest without dependence on operator self-reporting or foreign intelligence services.

The operational payoff is concrete. A ministry of energy gains an independent cross-check on domestic refinery compliance with production quotas and environmental permits. A central bank gains a real-time proxy for industrial activity unmediated by statistical lags. And a defence or foreign affairs ministry gains visibility into adversary refining capacity that no commercial data vendor will reliably provide during a geopolitical crisis — precisely when the data matters most.

What matters

Floating-roof tank shadow geometry yields inventory changes to ±2% volume, which, differenced daily, proxies crude intake rates directly.
Thermal infrared at 60–100m resolution discriminates hot distillation units from cold standby plant, exposing utilisation rates competitors do not disclose.
During sanctions or conflict, commercial data vendors suspend service or self-censor; sovereign imagery is the only source that remains online.
Refinery throughput is a leading indicator of jet fuel, diesel and petrochemical output — critical inputs to national mobilisation and wartime logistics planning.

Sovereignty score: 8/10 — Independent refinery throughput intelligence is a strategic energy-security asset that no nation should outsource to a vendor who may suspend service, self-censor, or be subject to foreign export controls precisely when the data is most critical.

Commercial data vendors operating under US EAR or EU dual-use regulations can be compelled to restrict imagery delivery to sanctioned regions or during declared conflicts, cutting off access at the moment of maximum operational need.
Domestic refinery compliance monitoring — against environmental permits, production quotas and tax obligations — requires continuous, auditable data that cannot rest on operator self-reporting alone; sovereign imagery provides the independent evidentiary record.
Adversary refinery capacity is a direct input to military logistics and economic warfare assessments; relying on allied intelligence services for this data creates dependency and introduces the risk of withheld or delayed sharing during diplomatic tensions.
National energy statistics agencies face multi-week reporting lags from industry submissions; a sovereign satellite-derived throughput signal enables real-time economic monitoring independent of the national statistics pipeline.
