Aliso Canyon Oil Field has been out of commission since October of 2015, when the Southern California Gas Company discovered an underground natural gas storage well in the facility had blown out. The company was not able to plug the leaking well for nearly four months, forcing local families to evacuate. Ultimately, Aliso Canyon released about as much methane, a potent greenhouse gas, as the entire Los Angeles Basin does in a year.

Across the country, companies keep extra natural gas in aging underground wells that weren't originally designed for such storage.
