Currently, there is no real-time data available on air quality at hundreds of thousands of remote oil and gas well locations across the nation. Methane, the primary constituent in natural gas, is lighter than air, odorless, and invisible, making leaks extremely difficult to detect. Canary continuously monitors for unintended leaks of methane and VOCs. Powered by the sun, Canary operates for years without service, and eliminates unnecessary trips for random inspections. Canary ensures rapid response when something goes wrong, and streamlines field operations while safeguarding our communities and our planet. There are nearly 600,000 natural gas wells producing in the US today. These wells are carefully engineered to minimize the risk of natural gas leaks. The companies that operate these wells know that a leak costs them money. Project Canary is designed to facilitate early detection.
