Abandoned US Oil/Gas Wells Leaked 218,000 Tons Of Methane In 2018; Bankrupt Owners Won't Care Or Fix
EDIT
More than a century of oil and gas drilling has left behind millions of abandoned wells, many of which are leaching pollutants into the air and water. And drilling companies are likely to abandon many more wells due to bankruptcies, as oil prices struggle to recover from historic lows after the coronavirus pandemic crushed global fuel demand, according to bankruptcy lawyers, industry analysts and state regulators.”
Leaks from abandoned wells have long been recognized as an environmental problem, a health hazard and a public nuisance. They have been linked to dozens of instances of groundwater contamination by research commissioned by the Groundwater Protection Council, whose members include state ground water agencies. Orphaned wells have been blamed for a slew of public safety incidents over the years, including a methane blowout at the construction site of a waterfront hotel in California last year.

The U.S. figures are sobering: More than 3.2 million abandoned oil and gas wells together emitted 281 kilotons of methane in 2018, according to the data, which was included in the U.S. Environmental Protection Agency’s most recent report on April 14 to the United Nations Framework Convention on Climate Change. That’s the climate-damage equivalent of consuming about 16 million barrels of crude oil, according to an EPA calculation, or about as much as the United States, the world’s biggest oil consumer, uses in a typical day.

The actual amount could be as much as three times higher, the EPA says, because of incomplete data. The agency believes most of the methane comes from the more than 2 million abandoned wells it estimates were never properly plugged.

While 1985 started out as a good year for gas, by its close, more than half the nation’s oil and gas wells had shut down. How much money the Amerada Hess Corp., which bankrolled the dig, managed to pump out of gas well No. 095-20708 before that bust isn’t known. By 1990 the company, now called simply Hess Corp., gave up and sold it. Over the next decade or so, four more companies would seek the riches promised at the bottom of the well, seemingly with little success. In 2001 a state inspector visited the site. “Looks like it’s dying,” he wrote.
Gas wells never really die, though. Over the years, the miles of steel piping and cement corrode, creating pathways for noxious gases to reach the surface. The most worrisome of these is methane, the main component of natural gas. If carbon dioxide is a bullet, methane is a bomb. Odorless and invisible, it captures 86 times more heat than CO₂ over two decades and at least 25 times more over a century. Drilling has released this potent greenhouse gas, once sequestered in the deep pockets and grooves of the Earth, into the atmosphere, where it’s wreaking more havoc than humans can keep up with.
Well No. 095-20708 is also known as A.H.C. Church No. 11, referring both to Hess and to Bernard Church, who like so many in California’s Sacramento River Delta sold his farmland but retained the mineral rights in the hope that they’d make his family rich. The Church well is a relic, but it’s not rare. It’s one of more than 3.2 million deserted oil and gas wells in the U.S. and one of an estimated 29 million globally, according to Reuters. There’s no regulatory requirement to monitor methane emissions from inactive wells, and until recently, scientists didn’t even consider wells in their estimates of greenhouse gas emissions. With the pandemic depressing demand for fossil fuels and renewable energy development booming, why should owners idle or plug their wells when they can simply walk away?
In the past five years, 207 oil and gas businesses have failed. As natural gas prices crater, the fiscal burden on states forced to plug wells could skyrocket; according to Rystad Energy AS, an industry analytics company, 190 more companies could file for bankruptcy by the end of 2022. Many oil and gas companies are idling their wells by capping them in the hope prices will rise again. But capping lasts only about two decades, and it does nothing to prevent tens of thousands of low-producing wells from becoming orphaned, meaning “there is no associated person or company with any financial connection to and responsibility for the well,” according to California’s Geologic Energy Management Division. “It’s cheaper to idle them than to clean them up,” says Joshua Macey, an assistant professor of law at the University of Chicago, who’s spent years studying fossil fuel bankruptcies. “Once prices increase, they could be profitable to operate again. It gives them a strong reason to not do cleanup now. It’s not orphaned yet, although for all intents and purposes it is.”
