Seimic data represent a largely untapped source for characterising of fault zones. The key for using it lies in linking fault zone structure and properties to seismic response. The recent development of outcrop-based fault zone models allows this links to be studied. A seismic imaging procedure for fault zones, using multicomponent surface data generated for statistical fault facies models, is presented and discussed. It is based on a specific imaging procedure, which consists in a weighted summation of multicomponent multishot/multioffset data and spectral filtering of seismic data. The imaging procedure presented here is capable of resolving details inside the fault zone, which opens up for using seismic data to characterize sub-surface faults.
