Acknowledgements The authors gratefully acknowledge the assistance of Bob Klein, Dynamic Graphics, in the preparation and review of this paper. Simple unfaulted example. Ovals indicate where sand is observed in the well. Orthogonal grid interpolates properties incorrectly. Stratigraphic grid correctly interpolates between objects.
Displacement contours superimposed on fault surface.
Cross section showing consistency of three-dimensional faulted model. All data are now in stratigraphic space. Cross section through extensional model created using only a vertical shift of data. Properties interpolated only in one layer. Note that the properties do not match exactly across the faults.
