A lubrication fracture model in a poro-elastic medium

V Girault, MF Wheeler, B Ganis… - Mathematical Models and …, 2015 - World Scientific
We present a non-planar fracture model in a poro-elastic medium. The medium in which the
fracture is embedded is governed by the standard Biot equations of linear poro-elasticity and …

Modeling fractures as interfaces with nonmatching grids

N Frih, V Martin, JE Roberts, A Saâda - Computational Geosciences, 2012 - Springer
