The Standard Lithium demonstration plant near El Dorado has spent about six years pulling lithium from brine already pumped up for bromine production. And Energies Media reports it’s a model that could change how operators value aging oilfields across the country.
U.S. oil and gas fields produce huge volumes of salty wastewater, which operators treat as a disposal cost. Lithium worth recovering could turn that cost into a source of revenue, reporter Hugo Rojas writes.
“Chemistry that works at demonstration scale does not always translate directly to tens of thousands of tons a year. Still, El Dorado is a tidy illustration of how an industry built around one mineral can end up sitting on another.”
By the Numbers:
1957: The year South Arkansas began producing bromine from Smackover Formation brine.
One-third: The region’s share of the world’s bromine output.
5.1 million to 19 million tons: The U.S. Geological Survey’s estimate of lithium in southern Arkansas brines.
Rojas writes that brine chemistry varies from well to well, and results at demonstration scale don’t guarantee commercial-scale output.
