ExxonMobil tests 8 new methane detection technologies

ExxonMobil has begun field testing the effectiveness and scalability of eight potential methane detection technologies, from drones to fixed position sensors, meant to detect leaks and analyze possible solutions for reducing methane emissions.

These tests will be strung across nearly 1,000 sites in Texas and New Mexico, as a means of sussing out the most efficient method. Each test will chart real-time data and will be validated through field observations, optical gas imaging cameras and portable methane detection instruments.

“By testing the most promising methane detection technologies in a field environment, we are providing viable solutions that can be adopted by other producers to detect and reduce methane emissions,” Staale Gjervik, senior vice president of unconventional at ExxonMobil, said. “We are applying scientific rigor and taking aggressive steps to find commercially scalable and affordable solutions for all operators.”

ExxonMobil reports that, through some of these trials, it has already discovered methane sources that would not otherwise have been detected as quickly. Efforts can be broken down into four areas: aerial surveillance, satellite surveillance, truck mounted monitors and fixed-position monitors. The majority of efforts are in the aerial space, with Bridger Photonics, Scientific Aviation, Kairos Aerospace, Leak Surveys Inc., and SeekOps all deploying various measures to the tests. GHGSat is using a satellite to measure methane concentrations, leaks and emissions, while mAIRsure has offered truck-mounted autonomous sensors and wind sensors that continuously monitor for emissions.

During testing, ExxonMobil is also comparing measurements of downwind emissions using technology by Aerodyne Research.
