Monitoring Offshore Methane Emissions by Satellite

08 July 2021

TotalEnergies is partnering with GHGSat to develop a satellite imaging technology to monitor potential methane leak occurrences at offshore facilities.

This new technology, known as “Glint Mode”, annuls interference effects on data acquisition by observing sun glint on the ocean surface. This satellite imaging can be combined with local measurements for which TotalEnergies has developed the ultra-light AUSEA1 drone-mounted spectrometer, considered to be the most accurate in the world.

TotalEnergies and GHGSat have been working together since 2018 to refine methane emissions measurement thresholds in order to detect increasingly smaller emissions so that leaks can be prevented as far upstream as possible. In October 2020, the partners set a world record at TotalEnergies’ TADI2 testing complex, which is equipped with leading-edge detection resources, by successfully quantifying the smallest controlled leak detected to date. TotalEnergies and GHGSat are taking a new step with this initiative and will be conducting six satellite observations in Glint Mode of TotalEnergies offshore sites.

“As part of a continuous improvement program, TotalEnergies has decided to initiate a new stage in its collaboration with GHGSat to develop an innovative satellite mapping technology suited to offshore infrastructure. This technology will build on the methane emissions measurement system for which TotalEnergies holds the accuracy record and strengthen our position as a pioneer in developing methane emissions monitoring technologies,” said Marie-Noëlle Séméria, Chief Technology Officer at TotalEnergies.

“GHGSat is excited to expand its emissions monitoring work with TotalEnergies. By adding offshore measurements to its portfolio of satellite, airborne and analytical capabilities, GHGSat continues to enhance its services for market leaders like TotalEnergies,” declared Stéphane Germain, President of GHGSat.

This partnership builds on TotalEnergies’ commitment within the United Nations Environmental Programme (UNEP) Oil and Gas Methane Partnership (OGMP) to reduce the industry’s methane emissions.
