Take a look at most oil and gas infrastructure — wellheads, pipes and cylindrical storage tanks — dotting New Mexico oil and gas fields, and little seems to be happening. But use the right equipment and you can see gases, including methane, wafting into the air. Heading skyward with methane, the main component of natural gas and a greenhouse gas that contributes to global warming, are royalties some say the oil and gas industry could be paying New Mexico. An April report from Taxpayers for Common Sense, a national budget and taxpayer advocate, analyzed federal leases through the Office of Natural Resource Revenue and estimated that the gas lost nationwide on federal lands in 2016 was worth $75.5 million. Half of the gas lost between 2012 and 2016 came from New Mexico.
