Abstract

This paper presents a 3D parametric fault representation for modeling the displacement field associated with faults in accordance with their geometry. The displacements are modeled in a canonical fault space where the near-field displacement is summed up into a small set of parameters consisting of the maximum displacement amplitude and their profiles of attenuation in the surrounding space. The particular geometry and the orientation of the slip of each fault is then accounted for by mapping the actual fault onto its canonical representation. This mapping is obtained with the help of a curvilinear frame aligned both on the fault surface and slip direction. Such a model will help in including more geological concepts in quantitative subsurface models during the 3D structural modeling task. Its applicability is demonstrated in the frame of forward modeling and stochastic sequential fault simulation.
