  • Hong Yan: Geomechanics and rock physics for 4D overburden seismic
  • Maksym Lozovyi: Shale as a barrier around cased wells
  • Kim S Mews: 2-phase saturation and 4D seismic

Main research interest: Rock physics and rock mechanics for geoscience applications.

  • Stress dependent wave velocities in reservoir and overburden rocks (relation to 4D seismics)
  • Clay and shale physics
  • Borehole stability and formation of natural barriers in shale
  • Discrete particle modelling of sediment and sedimentary rock behaviour

My research is done in close cooperation with the Formation Physics group in SINTEF Industry, Petroleum department. I also act as a scientific advisor to SINTEF.
