Jan Hermanson
BSc Geology, Uppsala University, Sweden 1991
MSc Structural Geology, Uppsala University, Sweden 1992
Mr Hermanson is a structural geologist with extensive experinece in FracMan
theory and application. Mr. Hermason has been collecting and interpreting fracture
data from underground tunnels and caverns for over 5 years. Mr. Hermanson has
developed innovative tools for discrete fracture network visualization, and
has coupled FracMan to Intergraph workstation and database software.
Mr. Hermanson's fields of expertise include:
- Structural geologic techniques for collection of discrete fracture geometric
parameters
- 3D geological modelling
- Fractured rock data analysis (orientation, size, spatial structure and flow
properties)
- FracMan DFN modeling based on statistical parameters and conditioned field
measurements
- 3D visualisation technologies for fracture networks, including flow, transport,
and hydraulic properties
