Barry Freifeld is a Mechanical Engineer at the Lawrence Berkeley National Laboratory, where he is the principal investigator for numerous projects relating to CO2 sequestration and arctic hydrology. He received his BA in Applied Mathematics (UC Berkeley), his MS in Mechanical Engineering (UC Santa Barbara), and PhD in Civil and Environmental Engineering (UC Berkeley, 2001). He is an expert in the development of well-based monitoring instrumentation and techniques. His recent innovations include the U-tube geochemical sampling methodology, as well as thermal perturbation fiber-optic monitoring techniques for understanding subsurface processes. He has also received a U.S. patent for a portable whole-core x-ray computed tomography imaging system used at continental drill sites and on drilling vessels.
At Lawrence Berkeley National Laboratory my recent research has focused on: (1) geological sequestration of CO2, particularly field demonstrations in saline and depleted gas aquifers (2) understanding thermal and hydrologic conditions in arctic regions and (3) development of fiber-optic DTS techniques for monitoring subsurface processes. Currently I am the Principal Investigator for collaborations supporting two international carbon storage demonstration projects: the Otway Project in Victoria, Australia and the EU funded CO2SINK program in Ketzin, Germany.
