The potential-field method (Lajaunie et al., 1997) is used to create geological surfaces by interpolating from points on interfaces, orientation and fault data by universal cokriging. Due to the difficulty of directly inferring the covariance of the potential field, it is identified from the orientation data, which can be considered as derivatives of the potential. This makes it possible to associate sensible cokriging standard deviations to the potential-field estimates and to translate them into uncertainties in the 3D model.
