Methane Detection Sensitivity

Methane detection sensitivity refers to the smallest amount of methane a detection system can reliably identify and report. In aerial systems, this is usually measured in kilograms per hour (kg/hr). The lower the detection threshold, the smaller the leaks the system can detect.

Bridger Photonics’ Gas Mapping LiDAR™, when deployed aerially, offers industry-leading sensitivity capable of detecting methane emissions as low as 1 kg/hr, depending on conditions.

Why Methane Detection Sensitivity Matters for Leak Detection

Detection sensitivity directly affects how early and how often leaks are found. A system with high sensitivity can identify small leaks before they grow into bigger problems, allowing for faster repairs, reduced emissions, and better compliance outcomes.

For operators, greater sensitivity means:

• More comprehensive leak detection
• Better alignment with regulatory limits and performance standards
• Improved ability to track emissions trends over time
• Increased confidence in reported emissions data

It’s a key factor in comparing different detection technologies or providers, especially when evaluating aerial systems for LDAR, ESG, or regulatory programs.

How Methane Detection Sensitivity Works in Aerial Systems (Brief Technical)

Detection sensitivity, along with methane measurement accuracy, depends on both the sensor technology and environmental conditions. 

In aerial systems like Bridger’s, sensitivity is influenced by:

• Sensor type and precision (e.g., LiDAR vs. infrared)
• Flight altitude and speed
• Weather, wind, and atmospheric mixing
• Algorithms used to analyze raw sensor data

Bridger calibrates its Gas Mapping LiDAR™ system using controlled releases to ensure reliable detection of emissions as low as 1 kg/hr. This ensures performance is both consistent and verifiable under real-world conditions.

Key Applications of Methane Detection Sensitivity in Oil & Gas

• Detecting small leaks before they escalate
• Comparing service providers or technologies for LDAR programs
• Supporting compliance with state, federal, or voluntary methane targets
• Tracking emissions performance with greater accuracy
• Demonstrating detection capabilities to regulators or stakeholders
