In this thesis, we are interested in the modelisation of fluid flow along conductive faults. This model, so-called double interface model tackles two majors difficulties encountered when modelising faults. First of all, the use of an interface model, in which the faults are represented by lower dimension elements allows to treat the problem of space scale. Then, the use of two interfaces to modelise each fault allows to handle quite naturally the non-matching grid problem arising from this kind of problem. The question of non-planar fault and fault networks is also addressed. This model is then validated on several academic test cases and a synthetic case inspire by CO2 storage is also performed. Finally, a theoric study is also conducted in order to validate our approach.
