Cleaning up abandoned wells is proving to be costly to G&O producing states. These wells are called orphaned wells. Orphan wells are when extraction companies abandon their wells and leave the cleanup to the taxpayers.
At the work site in Adams County, Colo., northeast of Denver, the orphan well unit is preparing to close off an abandoned well.
They have more than 250 of those high-risk wells to cap by 2023, and in the past year they’ve plugged only 10.
Instead of drilling a mile beneath the surface to extract oil, they’re about to rip pipe out of the ground. In its place, they’ll leave concrete plugs strong enough to seal the hole permanently.
The well in question is known as an “orphaned well.” When G&O companies go bankrupt or stop taking care of their equipment, their wells fall into the state’s hands.
Thus, the term “orphaned.”
As the current administration looks to roll back regulations to boost the O&G industry, more states with growing energy production are grappling with how to handle these types of wells, some of which pose a danger to nearby homes and schools.
The EPA estimates there may be more than 1 million of these orphans scattered across the country.
Last year in Colorado, the state Legislature approved a tenfold increase in funding for orphaned well cleanup. States like Alabama and Ohio have followed suit. As did Pennsylvania, where the state Department of Environmental Protection estimates there could be up to 560,000 abandoned wells.
This led to crews like the one working northeast of Denver, which are saddled with demanding schedules, heavy equipment, explosives and other factors that make working conditions dangerous.
Some orphaned wells are more than 100 years old. Others were drilled within the past decade. Many lack proper state records, meaning crews have to improvise when cleaning them up.
At the edge of the site, Mike Hickey, an engineer with the Colorado Oil and Gas Conservation Commission’s orphan well unit, braces himself for the day ahead.
“We never operated this well,” Hickey said. “So we’re not completely sure what’s in it until we start pulling it out.”
In front of him, the rig fires up.
There are a variety of ways wells become abandoned. The well stops producing, they stop taking care of their equipment, multiple violations to the company, and bankruptcy.
The Colorado Oil and Gas Conservation Commission knows of 275 orphaned wells and 422 associated locations or facilities. There are likely many more.
In Wyoming, thousands of wells were orphaned in 2014 after a coal bed methane bust. Their owners lacked the money to clean them up, so they became the state’s problem.
In response, the Wyoming Oil and Gas Conservation Commission expanded its cleanup program. It has since plugged more than 2,300 wells. Crews have also repurposed more than 100 into new water wells.
Jill Morrison, executive director of the Powder River Basin Resource Council, an environmental group in Wyoming, says every state that has oil and gas is struggling with the cleanup task “because the industry has not been held accountable by the regulators and by the government to pay the cost of doing business.”
Morrison also worries another bust could put Wyoming’s orphan well program budget over the edge.
“We’re going to quickly be in the tens of millions of dollars responsible for plugging and reclaiming oil and gas wells if we don’t require upfront bonding,” she said.
That means making companies pay the full cost of plugging wells even before they start drilling.
Mark Watson, WOGCC supervisor, says he’s less concerned about a similar situation happening again. He points to a law passed in 2016 that allows the state to examine an operator’s financials prior to drilling.
“We’re being more proactive with the companies,” Watson said. “We keep a lot closer tab on these operators than we did before.”
But the industry pushes back on the idea.
A week of work
But the state remains concerned about these wells. Colorado has set a deadline of 2023 to get the highest-risk ones plugged.
That includes the well northeast of Denver.
Hickey’s crew uses explosives to crack the rock around the well and then pours in concrete to seal it shut — nearly a week after starting the whole process.
“And then we cut it off 4 feet down, weld a cap on it, put identifying information on that cap, bury it, and sweep the floor,” he says.
Hickey says his crew is working as hard as it can to meet the state’s 2023 deadline.
“We just got to get them cleaned up,” he says. “They’re not supposed to be this way. They’re contrary to our rules, and it’s our job to fix them.”
But progress is slow. They have more than 250 of those high-risk wells to cap, and in the past year they’ve plugged only 10.
The crew hopes to move faster, but it’s still unclear whether it will finish the job in time.
