Additionally, the incorporation of TV constrains proves crucial in mitigating artifacts introduced by noisy data and inaccuracies in source functions. Numerical experiments unequivocally demonstrate the resilience of SITV-FWI when...

..., May 18-22, 2024. ABSTRACT The Biot (or Biot-Willis) coefficient is an important parameter for geomechanical models. It dictates the effective stress for rock compressibility. This parameter can be measured in the laboratory with careful geomechanical experiments, which can give accurate results...

Physically, the nano-environment translates to low permeability, difficult rock preparation, and extensive experimental time, especially for steady-state flow experiments. Representative three-dimensional digital rocks were...
