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.
