Title: METHOD AND SYSTEM FOR INTERPOLATING DISCONTINUOUS FUNCTIONS IN A SUBSURFACE MODEL
Abstract:
A method and system are described for creating a subsurface model. In this method, discontinuous functions are interpolated in a subsurface model. The method extrapolates specified values over discontinuous manifolds by embedding the manifold in a higher- dimensional space that amplifies distances across discontinuities and thus eliminates special consideration to prevent extrapolation across discontinuities. The resulting subsurface model may be used in reservoir simulations and hydrocarbon operations.
