yes, the field is gaining quite a lot of momentum. The EU is publishing free images from satellites Sentinel-5P with a dedicated instrument called TROPOMI, and the Netherland space research center is crunching those to detect methane plumes. They publish it every week there https://earth.sron.nl/methane-emissions/ (and yes it's mostly oil&gas).
Another nice resource on the topic (not just satellite images, but also small sensors) https://www.methanefix.tech/. Also this research program on methane removal https://www.sparkclimate.org/methane-removal/home
that methaneFix link is literally just a couple of show-offs! I like the effort.. there is a difference between the large orgs, large institutions and then those web people..
The TROPOMI link is very dense and yes, exactly what the references above are.. excellent, so much to do
