Biography

Matthew Reagan is a Staff Scientist in the Energy Geosciences Division (EGD) at Lawrence Berkeley National Laboratory. He specializes in research on the thermodynamics, transport, and chemistry of aqueous and hydrocarbon systems in the subsurface, including research on shale gas and shale oil reservoir simulation and engineering, thermodynamics of gas hydrates, methane hydrates as a resource, data reduction and uncertainty, the coupling of methane hydrates and global climate, and the impacts of oil and gas production on the environment.

Research Interests

  • Fundamental and applied research on the thermodynamics, transport, and chemistry subsurface systems, including:
      • The thermodynamics of gas hydrates and the simulation of methane hydrate reservoirs
      • The consequences of ocean warming on methane hydrates, and the links to global climate feedbacks
      • The potential for gas or contaminant release during hydraulic fracturing or complex deepwater drilling
      • Production from fractured shales, tight reservoirs, and other unconventional resources
      • The use of high-performance computing and parallel simulators for large-scale subsurface simulation
      • Data reduction, machine learning, and uncertainty quantification using statistical methods
  • Developer for the TOUGH family of numerical simulation codes, programming libraries, and public-facing tools for physical property estimation
  • Authored or co-authored 58 peer-reviewed papers, two regulatory studies, and 44 articles and reports
  • Gave over 55 technical presentations, including 7 invited talks
