Non-producing oil and gas wells may emit microbial methane at rates 1,000 times higher than previously estimated
A study led by McGill University researchers found that non-producing oil and gas wells in Canada emit microbial methane at rates 1,000 times higher than previously estimated. The research highlights the complexity of subsurface methane sources and raises questions about emissions pathways, emphasizing the need for better understanding to manage methane leaks effectively.
