Of the approximately two dozen medical CT scanners scattered throughout Stanford’s main campus and medical centers, two can be found nestled in basement labs of the Green Earth Sciences Buildings.

The scanner duo is being put to some decidedly off-label uses in research led by Anthony Kovscek, a professor of energy resources engineering at Stanford’s School of Earth, Energy & Environmental Sciences (Stanford Earth). The machines in this case have helped scientists extract oil and gas more efficiently, and are now revealing ways of storing carbon dioxide (CO2) deep underground while the world continues to rely on fossil fuels for energy and transportation.
