I'm in the IoT space and interestingly had a lot of contact in the last 6 months with firms doing contract work for the oil companies, or providing private services to monitor methane for working wells. The regulatory structures have been changing a lot lately, and now the old methods like flying over a field of wells and measuring aggregate methane levels is no longer sufficient. There now is a lot of interest and energy behind doing per-well monitoring. I'm hoping that this means wells 50 years from now will be safer, but unfortunately it doesn't address a lot of the old wells that are a problem today...
