Geomechanics

Flow module (with pressure –dependent k and )

Geomechanical module time T0 T1 T2 … P k, At the end of each exchange time increment :

  • Mechanical module reads in new pore pressures
  • Mechanical module calculates new stresses and induced deformations
  • Mechanical module (or flow module) computes new permeability/porosities from the

knowledge of strains/effective stresses

  • Flow module reads in the new flow properties and use it in computations for the next

time increment
