Paleokarst networks are complex, multi-scale, heterogeneous features that are commonly modified by gravitational, structural and diagenetic processes during burial. In subsurface carbonate reservoirs, paleokarst systems can be a source of significant heterogeneity and complexity. Although 3D seismic data commonly can reveal exquisite details of paleokarst systems at the level of the ‘top reservoir’, the beauty and use of such images is normally superficial. This is because horizon-based interpretations reveal little of the three-dimensional paleokarst network within the reservoir. In order to extract a more complete 3D representation of paleokarst systems, we have focused on the utilisation of volume-based methods...
