PNNL

Jeff Burghardt is an Earth scientist at PNNL with over ten years of experience in experimental and computational geomechanics. His dissertation work focused on modeling large deformation and high rate constitutive behavior of rock and soils using the Material Point Method and Finite Element Method. Subsequently, he spent five years working in R&D and operations for an oilfield service company, Schlumberger, where he led several large interdisciplinary research projects focused on hydraulic fracturing, stress estimation, and drilling for unconventional petroleum reservoirs. He joined PNNL in 2016, where he has continued to work on experimental and computational geomechanical research with application areas in geothermal energy, geologic carbon storage, and upstream oil and gas. He is the developer of the National Risk Assessment Program State of Stress Assessment Tool, which is designed to help CO₂ storage site operators estimate geomechanical risks.
