Precision Methane Detection: How Laser-Equipped Drones Are Transforming Emission Monitoring in Oil & Gas
Detecting methane fugitive emissions is critical for ensuring safety and effective asset management in the oil and gas industry. Traditionally, Precision Methane Detection have been identified through driving surveys using vehicles outfitted with various sensors. However, this conventional method faces several challenges:
- Technical Limitations: Commercial methane detectors can struggle with sensitivity and precision.
- Terrain Accessibility: Vehicles may not be able to safely or reliably traverse certain areas.
- Remote Locations: Extended asset networks, such as pipelines, often run through remote regions, making data collection both time-consuming and challenging.
To address these issues, PERGAM has developed a groundbreaking solution—a drone equipped with a laser sensor designed to detect surface fugitive methane emissions and accurately geo-reference the emission source. This technology enables a more targeted risk assessment by refining emission flux calculations across an entire oil and gas site, thereby reducing uncertainty and facilitating effective remediation planning.
The FALCON operates by emitting an infrared laser beam downward from the drone and analysing the light that reflects back. Methane present in the laser’s path attenuates the beam at specific wavelengths compared to others. By flying in circular patterns around a suspected leak, the system can deduce both the leak rate and its precise location.
In addition to its applications in the oil and gas sector, drone-based methane detection is transforming landfill management. Traditionally, landfill issues have been addressed only after they become apparent. However, growing environmental concerns and tighter regulations demand a proactive approach.
Precision Methane Detection – A two-step procedure has been implemented:
- Detection: Thermal cameras first identify variations in surface temperatures, highlighting potential hotspots. Simultaneously, the Laser Falcon sensor system measures gas concentrations to pinpoint methane emissions.
- Analysis: Data collected by drones is processed to create detailed thermal and gas maps of landfill sites. These maps allow operators to assess and prioritise areas that require immediate attention.
The advantages of drone-based methane detection are substantial
- Proactive Monitoring: Regular drone surveys enable early detection of hotspots and methane leaks, preventing minor issues from escalating.
- Cost Efficiency: Early intervention significantly reduces the expenses associated with extensive remediation efforts.
- Environmental Protection: Prompt detection and management of emissions help minimise environmental contamination, supporting regulatory compliance and reducing the overall environmental footprint.
Field deployments of this innovative technology have consistently demonstrated its effectiveness. Operators can now act swiftly based on reliable data, preventing subsurface fires and reducing greenhouse gas emissions. As these systems prove their worth in real-world applications, they stand out as essential tools for modernizing both oil and gas infrastructure and landfill management operations.
