Just one orphaned site in California could have emitted more than 30 tons of methane. There are millions more like it.
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.
