🇺🇸🛢 America’s Biggest Oil Field Is Turning Into a Pressure Cooker

Drillers’ injection of wastewater is creating mayhem across the Permian Basin, raising concern about the future of fossil-fuel production there

Shale drillers have turned the biggest oil field in the U.S. into a pressure cooker that is literally bursting at the seams.

Producers in the Permian Basin of West Texas and New Mexico extract roughly half of the U.S.’s crude. They also produce copious amounts of toxic, salty water, which they pump back into the ground. Now, some of the reservoirs that collect the fluids are overflowing—and the producers keep injecting more.

It is creating a huge mess.

A buildup in pressure across the region is propelling wastewater up ancient wellbores, birthing geysers that can cost millions of dollars to clean up. Companies are wrestling with drilling hazards that make it more costly to operate and complaining that the marinade is creeping into their oil-and-gas reservoirs. Communities friendly to oil and gas are growing worried about injection.

“It’s one of the many things that keep me up at night,” said Greg Perrin, general manager of the groundwater-conservation district in Reeves County, Texas, where companies are injecting some of the largest volumes of wastewater.

Swaths of the Permian appear to be on the verge of geological malfunction. Pressure in the injection reservoirs in a prime portion of the basin runs as high as 0.7 pound per square inch per foot, according to a Wall Street Journal analysis of data from researchers at the University of Texas at Austin’s Bureau of Economic Geology.

When pressure exceeds 0.5 pound per square inch per foot, the liquid—if it finds a pathway—can flow to the surface and pose a risk to underground sources of drinking water, Texas regulators have said in industry presentations.
