Patent ID: 8600708

Claim:
A method for perturbing an initial three-dimensional (3D) geological model including a fault using a 3D vector field, the method comprising: generating a coherent 3D vector field comprising 3D vectors, wherein each 3D vector of the 3D vector field is associated with a node of the initial 3D geological model and has a magnitude within a range of uncertainty of the node of the initial 3D geological model associated therewith; and applying the coherent 3D vector field to the initial 3D geological model including the fault to generate a perturbed 3D model, wherein the perturbed 3D model differs from the initial 3D geological model by a displacement defined by the 3D vector field associated with nodes having uncertain values, wherein the 3D vector field is coherent such that the divergence of the 3D vector field is greater than (−1) and less than ( 3/2); and displaying the perturbed 3D model.
