U.S. gas companies abandon leaky wells

The story of gas well No. 095-20708 begins on Nov. 10, 1984, when a drill bit broke the Earth’s surface 4 miles north of Rio Vista, Calif. Wells don’t have birthdays, so this was its “spud date.”

The drill chewed through the dirt at a rate of 80 ½ feet per hour, reaching 846 feet below ground that first day. By Thanksgiving it had gotten a mile down, finally stopping 49 days later, having laid 2.2 miles of steel pipe and cement on its way to the “pay zone,” an underground field containing millions of dollars’ worth of natural gas.

The drilling rig arrived two months later, in early January. 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 CO 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.
