Gas Mapping LiDAR™ (GML)

Gas Mapping LiDAR™ (GML) is Bridger Photonics’ proprietary aerial methane detection technology. It combines laser-based sensors with advanced data processing to detect, locate, and quantify methane emissions from oil and gas infrastructure, all from the air.

Unlike traditional inspection methods, Gas Mapping LiDAR delivers geospatial data with quantified emission rates, enabling fast, accurate surveys across entire basins or regions. It’s built specifically to support leak detection, compliance reporting, and emissions reduction strategies.

Why It Matters

Methane is invisible to the naked eye, but it’s a critical target for emissions management and regulatory compliance. Gas Mapping LiDAR turns methane leaks into measurable, mappable data that oil and gas operators can act on.

Benefits include:

• Wide-area scans completed up to 10 times faster than ground crews
• Quantified emission rates to support compliance and ESG reporting
• Geo-located results for efficient repair planning
• Consistent, repeatable results for tracking mitigation progress

By combining advanced LiDAR hardware with proprietary data analytics, Bridger’s Gas Mapping LiDAR helps operators reduce emissions, improve operational efficiency, and meet evolving regulatory requirements.

How It Works (Brief Technical)

Gas Mapping LiDAR uses aircraft-mounted LiDAR sensors that emit laser pulses toward the ground. As the laser travels through the air, methane plumes absorb specific wavelengths of light. The system detects this absorption and calculates methane concentrations along the flight path.

Here’s what the process looks like:

• The aircraft flies a pre-planned route over oil and gas infrastructure
• The LiDAR system emits rapid pulses of light and measures the return signal
• Methane concentrations are calculated based on absorption patterns
• Proprietary algorithms localize the leak source and quantify the emission rate
• The result is a high-resolution, geo-tagged emissions map for each site
  
  

Key Applications in Oil and Gas

• Detecting and quantifying fugitive methane emissions
• Surveying entire oil and gas basins efficiently
• Supporting LDAR, OGMP, OOOOb, and other regulatory programs
• Setting and tracking ESG goals
• Prioritizing and validating leak repairs
• Streamlining compliance and audit preparation
