A new instrument developed at the Geosciences Measurement Facility at Lawrence Berkeley National Laboratory will help scientists working to identify ways to improve enhanced geothermal systems technologies for better access to clean energy. The SIMFIP tool will help research scientists from the eight national labs and six universities that make up the Enhanced Geothermal Systems Collab Project monitor the rock fractures they stimulate and study to improve what we know about how fluid flows through subsurface rock.
