Abstract

The GeoChron model is used to estimate fracturation of a deformed sedimentary layer using a parametric representation of the ante-deformed geological structure. Using the elasticity solid theory of continuous media, we derive several structural attributes (dilatation coefficient, principal strains, etc.) that may be used to define fracture zones using failure criteria. This approach quantifies deformations and gives good results in the case of theoretical cases such as the thin plates. It also gives useful strain parameters that can be related to the observed faults. This general theoretical framework provides solutions to complex problems such as determination of strains resulting from tectonic events and for predicting faulted zones on reservoirs. The next step is to use these structural attributes as secondary variables to estimate the fracture density and finally the permeability of a reservoir.
