It’s long been an open secret that abandoned oil and gas wells are dramatically undercounted in the United States. Now that the federal government is finally offering substantial funding to plug and clean up these environmental hazards, states are finally starting to admit it.

From 2020 to 2021, the number of wells that the state of Oklahoma listed as abandoned — and therefore the government’s responsibility to clean up — jumped from 2,799 to a whopping 17,865. In Colorado, the orphan well tally hovered around 275 from 2018 to 2020 but increased by almost 80 percent last year. In California, the tally almost doubled in the last two years. (It started even lower in 2019, when the state identified just 25 abandoned wells.)

What changed? In 2020, Congress began seriously considering sending states money to plug orphan wells. The proposal had support from both political parties and was ultimately included in the Bipartisan Infrastructure Law enacted in November, which set aside $4.7 billion for this purpose. States have long known that their orphan well tallies are outdated and incomplete, but without a source of funding to clean up the wells, many didn’t invest the resources required to identify abandoned wells. That changed as the funding slowly became a reality over the past couple of years.
