Mc. Cacas et al., MULTISCALE MODELING OF NATURALLY FRACTURED STRATIFIED SEDIMENTARY-ROCKS, Comptes rendus de l'Academie des sciences. Serie II. Sciences de la terre et des planetes, 324(8), 1997, pp. 663-668
We propose a new approach for modelling joint systems in oil reservoir
s in sedimentary stratified media. This approach combines a determinis
tic analysis of the spatial variation of mean fracture attributes at t
he ''global'' scale (a few kilometers) and a 3D stochastic modelling o
f the fracture system at the ''local'' scale (a few tens of meters). T
he global model is used to calibrate the parameters of the random proc
edure used to build the discrete model of fracture network. Different
concepts are used to analyse systematic joints and fold-related joints
. This approach should be more predictive than usual statistical model
ling of fracture patterns.
