This paper describes the building, data acquisition and interpretation of a complex physical model, SALNOR, built to illustrate a ''typical'' complicated North Sea geological structural sequence. The model was built as a proprietary project for Statoil who then released it to the Allied Geophysical Laboratories (AGL). The model consists of seven layers that represent the Top Palcocene, Top Cretaceous, J-Uniformity, Top Brent, Base Brent, Top Stratfjord, and Base Statfjord. The respective model material used were 3120 (red), 184 (clear), 3110 (white), 3120, 3110, 3120, and 3110 RTV silicone rubber to represent pre-cretaceous rocks. In order to graphically illustrate the complex structure, the model was cut into 16 square blocks. ''Wells'' were also cored in the center of each of these 16 blocks. This allows the seismic data to be directly tied to the reflection sources. The interactive computer graphics interpretation is illustrated with a 16 mm movie. The movie specifically illustrates the value of rapid animation through a sequence of vertical, horizontal or mixed vertical and horizontal seismic sections. The movement brings ''alive'' the geologic structures and stratigraphic sequences and allows the interpreter to make a rapid evaluation of the best prospects.
