Confidently and unambiguously identify methane leaks

Page last modified
February 22 2024

The methane lidar camera from SLB End-to-end Emissions Solutions uses laser imaging, detection, and ranging (lidar) technology to detect, locate, visualize, and quantify methane emissions from oil and gas facilities. A near-infrared laser beam is rastered across the facility and backscattered light from methane in the air is detected by sensitive single-photon counting modules. The lidar data provides high-resolution 3D methane concentration maps which are overlaid on visual images from an integrated camera. This unambiguously reveals leak locations. Automated image analysis also determines emission rates. The camera can detect emissions as small as 0.4 kg/hr from up to 200 meters away under ideal conditions. It is insensitive to background interference from sunlight, temperature variations, and other gases. The methane-specific lidar technology enables continuous monitoring and early leak detection to support rapid leak repair and accurate emissions source identification. it is applicable to onshore oil and gas production and processing facilties and large facilities with limited line of sight to potential emissions sources.
