Box 8013 N-4068 Stavanger Norway Taking on increasingly complex reservoirs and geometries that cannot practically be represented by bounding surfaces such as top and base horizons (e.g. carbonates channels salt...) necessitates a new generation of volume interpretation tools. The truly threedimensional nature of seismic data makes working in terms of volumes instead of primitive surfaces more attractive and convenient. Volume interpretation also provides better handling of geometries induced by volume properties that are not directly represented in a surface framework. An important
