Mind you, identifying leaks isn’t enough; it takes actively fixing them and decommissioning the infrastructure which resulted in methane release in the first place.

Unfortunately these satellites don’t have a high-enough resolution for oil and gas source attribution in most cases. They’re great for CAFOs and landfills, though.
My understanding is that the plan is to use a mix of high-frequency-low-resolution imaging with less-frequent-higher-resolution images to pinpoint specific leak sources.
That’s true, but because oil and gas emissions are stochastic in nature, it’s expensive and difficult to get enough measurements from airplanes and drones to really fill in the gaps. There are also only so many planes available that can do this kind of measurement. MethaneAir is one. The state of Colorado has funded these kinds of flights, but only for a few weeks per year and only for a small subset of the oil and gas industry in the state.
These flights also have to be planned long in advance and it’s difficult to react to emissions seen from satellites. This part will hopefully improve as time goes on.
