Flaring Detection

Detecting, quantifying and attributing gas flares at oil and gas facilities using shortwave-infrared and thermal satellite payloads to enforce environmental compliance and expose unreported combustion.

Satellite thermal infrared and SWIR sensors catch illegal and wasteful gas flaring that ground inspectors miss, giving regulators and operators irrefutable, time-stamped evidence at basin scale.

Routine gas flaring wastes an estimated 140 billion cubic metres of natural gas per year and emits hundreds of millions of tonnes of CO₂ and methane equivalents globally. National regulators and finance ministries rarely have an independent view of what is actually burning at remote upstream sites—they depend entirely on operator self-reporting, which carries obvious incentive to understate. Without sovereign satellite coverage, a government cannot distinguish a brief, legally sanctioned pressure-relief flare from weeks of continuous unreported combustion.

Shortwave-infrared (SWIR) sensors in the 1.6 µm and 2.2 µm bands cut through daytime solar glare and night-time darkness to resolve individual flare stacks and quantify radiant heat flux. Paired with a thermal infrared (TIR) channel at 3.9 µm, the constellation can estimate flame temperature and combustion efficiency, separating clean burns from smoky, methane-rich incomplete combustion events. A 16-satellite walker constellation at 550 km revisits any point on the equator every 2–3 hours—sufficient to catch episodic flares that disappear before the next Landsat or Sentinel overpass.

The operational output is a continuously updated national flare registry: every detected event geo-tagged, timed and attributed to a licensed block or operator, with radiant power converted to estimated gas volume via published combustion models. Regulators can issue penalty notices backed by independent satellite evidence; the ministry of finance gains a cross-check on royalty declarations; and international climate negotiators arrive at COP with audited national flaring totals rather than contested estimates. Renting this from a commercial provider means the evidence chain is controlled offshore—inadmissible in some jurisdictions and subject to vendor data-access policies the sovereign has no power to alter.

What matters

SWIR radiant power at 2.2 µm correlates directly to flared gas volume via the Combustion Source Characterisation model, giving regulators an independent volume estimate without operator cooperation.
Episodic flares lasting 30 minutes or less are systematically missed by polar-orbiting imagers with 12-hour or longer revisit; a 16-satellite constellation closes that gap to under 3 hours.
Incomplete combustion events emit up to 40% of methane unburned—TIR-derived combustion efficiency flags these for immediate enforcement rather than after annual audit.
Sovereign flaring data is the audit baseline for national NDC reporting under the Paris Agreement; outsourcing it to a foreign vendor creates a verifiable-data dependency that can be exploited or withdrawn at will.

Sovereignty score: 8/10 — A government that cannot independently detect and quantify flaring on its own territory surrenders both its environmental credibility and its royalty enforcement capacity to the honesty of operators and the goodwill of foreign data vendors.

Royalty and penalty revenue: operator-declared flaring volumes directly determine tax and penalty calculations worth hundreds of millions of dollars annually in major producing states; independent satellite evidence is the only unimpeachable counter.
NDC and climate treaty exposure: Paris Agreement transparency mechanisms require independently verifiable national emission inventories; a sovereign that relies on a foreign commercial provider cannot guarantee uninterrupted access to its own historical baseline at future COPs.
Data jurisdiction and legal admissibility: enforcement proceedings require evidence gathered under a defined chain of custody; data hosted and processed on foreign infrastructure may be inadmissible in national courts or subject to third-party access under the provider's domestic law.
Geopolitical leverage over operators: a national flaring satellite gives regulators the ability to act unilaterally against any operator, including state-owned majors from rival nations, without depending on a commercial vendor whose commercial relationships may create conflicts of interest.

Caveats: Thick smoke plumes from incomplete combustion can attenuate SWIR signal by up to 30%—TIR channel partially compensates but algorithm uncertainty should be flagged in enforcement notices; SWIR detector arrays from US suppliers may require export licences, so European (e.g. Sofradir/LYNRED) or Japanese (Hamamatsu) sources should be qualified at contract stage

Frequently asked

What wavelengths do satellites use to detect gas flares, and why does that matter?

Flares emit strongly in the shortwave infrared (SWIR, 1.3–2.5 µm) and mid-wave infrared (MWIR, 3–5 µm) bands where combustion temperatures of 1,000–1,700 °C produce peak radiance. Thermal infrared (TIR, 8–12 µm) captures lower-temperature residual heat and smouldering events. A sovereign sensor designed for your basin should cover at least SWIR and MWIR to catch both active flame and hot-spot signatures, whereas visible-light satellites miss flares entirely during daylight hours.

Can a single satellite provide adequate national coverage, or does a country need a constellation?

A single satellite in low Earth orbit passes over any given oilfield once or twice per day at best, leaving gaps of 12 hours or more. Routine flaring violations frequently occur between passes. Effective national enforcement generally requires a constellation of at least 6–12 microsatellites to achieve sub-4-hour revisit at mid-latitudes, or commercial data-sharing agreements that aggregate multiple operators' assets — which reintroduces dependency on third parties.

How does a regulator turn a satellite thermal anomaly into an enforceable fine?

The satellite detection produces a geo-referenced thermal event with timestamp, radiant heat flux, and estimated flare duration. This is matched against the operator's flaring permit — typically specifying allowable volumes and durations — and combined with gas-composition data from ground samples or aerial sensors to estimate volumes flared under the IPCC 2019 Refinement methodology. The jurisdiction then needs legislation that explicitly accepts satellite-derived evidence; several jurisdictions, including the EU under the revised Methane Regulation (2024), now do so, but many producing nations have not yet amended their enforcement codes.

Is VIIRS free data sufficient for a national flaring programme, or do governments need to invest in dedicated sensors?

VIIRS Nightfire data from NOAA/NESDIS, freely available via the Earth Observation Group at Colorado School of Mines, is an excellent starting point and is used by the World Bank's GGFR programme. Its limitations are a ~750 m pixel resolution, a detection floor of roughly 2–3 MW, and a single daily overpass per satellite. For enforcement-grade monitoring — particularly of smaller operators and gathering systems — a dedicated SWIR microsatellite at 30–50 m resolution and sub-2-hour revisit is meaningfully superior.

What is the link between flare monitoring and methane emissions tracking?

Incomplete combustion in a gas flare releases methane directly into the atmosphere alongside CO₂. IPCC emission factors assume 98% combustion efficiency but real-world field studies published by agencies including NOAA and the Environmental Defense Fund suggest efficiencies as low as 85–92% in adverse wind conditions, meaning satellites designed only for thermal detection miss the methane fraction. Pairing a SWIR flare-detection payload with a hyperspectral methane sensor — as GHGSat and MethaneSAT do — provides a complete picture of both the combustion and the fugitive component.

Which nations have built or are building sovereign flare-monitoring satellite capability?

As of 2025, no low-income producing nation operates a dedicated sovereign flare-detection satellite; national capability is confined to a handful of space-faring states that leverage broad-purpose Earth observation programmes (ESA Sentinel-3, JAXA SLSTR on Copernicus, ISRO's Resourcesat-2A SWIR band). Iraq, Nigeria, and Algeria — the world's largest routine flarers by volume — all rely on commercial or international data. This is precisely the governance gap a sovereign nanosatellite or microsatellite programme at modest cost (sub-$80M for a 6-satellite constellation) could close.

How do satellite flare detections interact with national greenhouse gas inventories submitted to the UNFCCC?

National GHG inventories are compiled under IPCC guidelines and submitted annually to the UNFCCC. Flaring and venting from oil and gas are reported under the fugitive emissions category (1B2). Satellite-derived estimates are increasingly used to cross-check self-reported operator data; several countries have found that operator-reported flaring volumes were 30–60% lower than satellite-derived estimates. Owning the sensor means a government controls the authoritative number rather than defending its inventory against third-party satellite evidence it cannot replicate or audit.

What commercial providers currently sell flare detection data, and what are the risks of depending on them?

Key commercial providers include GHGSat (dedicated SWIR microsatellites), Kayrros (SWIR analytics on Sentinel and Landsat), Satellogic (SWIR constellation), and Ursa Space/Orbital Insight for ancillary context layers. The risks of dependency include contractual data-access restrictions, pricing power over sovereign clients, the risk that a provider's licence is suspended by its home-state regulator during a geopolitical dispute, and the absence of any right to ground-truth the provider's methodology. For a nation-state using this data to levy fines on multinational operators, such risks are not theoretical.
