UCLA Study Identifies Methane Super Emitter Sites

Live Poll

Should federal regulators enforce strict controls on methane emissions from oil and gas production sites?

A UCLA Law study conducted from January 2025 to June 2026 identified 91 methane plumes originating from 36 distinct sources in northwest Louisiana. The research utilized satellite imagery to pinpoint sites, including one location south of Shreveport that recorded a potentially record-breaking methane release.

Why it matters

Methane, which constitutes 70% to 90% of natural gas, contributes up to 25% of global warming. Identifying these leaks highlights both the environmental cost of infrastructure failures and the revenue lost by energy companies when product escapes through valves or aging wells.

The study recorded 91 methane plumes over a 17-month observation period using the Planet Labs Tanager 1 satellite. This instrument uses spectrometers to isolate methane signatures, identifying leaks across infrastructure in northwest Louisiana regions including the Haynesville and Bossier Shales.

The players

UCLA Law

A research institution focused on legal and environmental policy, known for tracking industry compliance and regulatory impacts.

Energy Transfer

A major midstream energy company managing a vast network of pipelines and natural gas infrastructure across the United States.

Planet Labs

An Earth-imaging company that operates a fleet of satellites, including the Tanager 1 system designed to monitor greenhouse gas emissions.

The details

The research employed the Tanager 1 satellite, which captures high-resolution spectral data to identify the distinct infrared absorption signature of methane gas. Carbon Mapper tracked the frequency of these plumes while UCLA Law researchers cross-referenced findings with public data to link specific leaks to operators. One site owned by Energy Transfer south of Shreveport was identified for a release that potentially qualifies as a record-breaking volume for U.S. onshore facilities.

Satellite imagery collection for the study occurred between January 1, 2025, and June 1, 2026.

The Tech Race

This study documents the prevalence of leaks in regions like the Haynesville and Bossier Shales as the Trump administration prepares to loosen federal methane regulations. The move to reduce oversight is projected to save oil and gas producers $45 billion, potentially altering industry incentives for leak detection.

Local communities near the Haynesville and Bossier Shales may experience varying air quality based on the operational efficiency of local natural gas wells. While Energy Transfer stopped emissions at one identified site, the long-term status of remaining plumes depends on pending federal regulatory changes.

The takeaway

The UCLA study confirms that significant, localized methane leaks remain common in mature production regions. Residents should monitor future shifts in EPA enforcement to see if these identified super emitter sites see increased maintenance or continued atmospheric venting.
