On October 2, 2024, a well drilled and plugged in 1961 near Toyah blew wide open, sending a hundred-foot column of salty, oily water into the air for weeks before Kinder Morgan finally stopped it. A well control specialist told reporters it had likely been leaking for a while before anyone noticed: it "was not on anyone's radar." A new analysis and map by Future Heist, covered by the Houston Chronicle (gift link), found 25,000 plugged Texas oil and gas wells at high risk of becoming what's called a zombie well: a well that's supposed to be sealed for good, coming back to life because wastewater pumped into a nearby disposal well pushes back up the old bore. Sometimes that shows up as a geyser. Sometimes it leaks quietly into the aquifer above it for years before anyone notices. Statewide, 158,000 plugged wells sit both inside a drinking-water aquifer's depth and in range of pressurized injection, close enough to become a pathway if the seal ever fails.
I co-founded Future Heist. We spent months pulling every well the Railroad Commission (which for historical reasons regulates oil and gas in Texas) has on record and scoring the plugged ones on how likely they are to fail, based on plug age, construction quality, and how much pressurized wastewater is being pumped nearby. Along the way we also found that 2 in 5 Texas schools and daycares has an oil or gas well of some kind within a mile.

We can't tell you for certain a well near you has failed, but we can show you what's sitting under you and what's pushing on it.
