The invention relates to a method of presentation and interpretation of three-dimensional seismic data (90). In particular, the invention relates to a method and apparatus for identifying volumetric subterranean regions bounded by a surface in which a specific seismic characteristic has a constant value. In one embodiment, three-dimensional seismic data (90) for a subterranean volume (60) is provided as input to a computer program (94) for performing "isosurface" processing of the data (90). This results in a graphical representation (Figure 5) of three-dimensional sub-volumes (60, 70) whose boundaries are defined by surfaces (62, 64) in which a specific seismic characteristic has constant value.
