Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, to identify geobodies for exploration and production activities. In one aspect, a method includes receiving seismic volume data regarding a geobody, generating an interpretation object by applying a multi-Z interpretation at representative intervals of edge-detected attributes through the seismic volume data, converting Z-value surfaces to points at each of the representative intervals, the Z-value surfaces generated by gridding polygons having been infilled and converted from the interpretation object, applying a mathematical addition or subtraction to generate a body of points representing the geobody by replicating the points at successive intervals, forming a blended 3D property model of the geobody by combining the seismic volume data resampled into a three-dimensional (3D) cellular grid, and enabling exploration activities by employing the seismic attribute analysis of the geobody identified based on the blended 3D property model.
