In a desolate stretch of desert spanning West Texas and New Mexico, drillers are pumping more crude than Kuwait. The oil production is so frenzied that huge swaths of land are literally sinking and heaving. The land has subsided by as much as 11 inches since 2015 in a prime portion of the Permian Basin, as drillers extract huge amounts of oil and water, according to a Wall Street Journal analysis of satellite data. In other areas where drillers dispose of wastewater in underground wells, the land has lifted by as much as 5 inches over the same period. Alongside crude, oil-and-gas companies are extracting gargantuan amounts of subterranean water—in the Delaware, between five and six barrels of water are produced, on average, for every barrel of oil. To dispose of it, they inject billions of barrels of putrid wastewater into underground disposal wells.
The constant extraction and injection of liquids has wrought complex geologic changes, which are raising concerns among local communities long supportive of oil and gas. Earthquakes linked to water disposal have rattled residents and prompted state regulators to step in. Some researchers worry that wastewater might end up contaminating scarce drinking-water supplies.
