WASHINGTONTwo U.S. senators introduced a bipartisan bill on April 13 to provide billions of dollars to plug oil and gas wells, nearly the level in President Joe Biden’s infrastructure plan, to provide jobs and cut emissions of a potent greenhouse gas.

More than a century of U.S. oil and gas drilling has left behind millions of abandoned wells, many of which are emitting methane into the atmosphere. Some wells also pollute waterways. Oil and gas companies are likely to abandon many more wells as renewable energy eats into demand for fossil fuels.

The Revive Economic Growth and Reclaim Orphaned Wells (REGROW) legislation, introduced by Ben Ray Luján (D-N.M.) and Kevin Cramer (R-N.D.), would provide $4.275 billion for orphaned well cleanup on state and private lands, $400 million for orphaned well cleanup on public and tribal lands, and $32 million for research and development.

Biden’s $2.3 trillion infrastructure plan urges Congress to pass $8 billion for plugging wells and $8 billion for reclaiming coal and uranium mines. The work would also create jobs in regions hurting amid the energy transition.

The senators said the oil and gas industry had lost more than 100,000 jobs since the beginning of the coronavirus pandemic. The bill “will put New Mexicans back to work while safeguarding our environment and reducing harmful air pollution,” Luján said, adding there are 700 orphaned wells in his state alone.

Pennsylvania, where the U.S. oil industry began, also has a lot of orphaned wells.

Legislation introduced last week by Rep. Teresa Leger Fernandez (D-N.M.), would provide the full $8 billion for plugging oil and gas wells.
