We tested and adapted seismic attributes techniques on a 2-D and 3-D multi frequency GPR dataset to image the network of stratigraphic joints and fractures, the lithological variations and to characterize the rock mass based on the response to the radar wavefield measured in an abandoned limestone quarry. We applied semi-automatic horizon mapping techniques using manually picked seeds (control points) on selected attributes and automatic extrapolation both on inline and crossline, starting from seed positions. The results were integrated and validated with direct outcrop measures and allowed to image an hydrocarbon reservoir analogue in 3-D up to a depth of over 10m below the topographic surface.

Abstract
We tested and adapted seismic attributes techniques on a 2-D and 3-D multi frequency GPR dataset to image the network of stratigraphic joints and fractures, the lithological variations and to characterize the rock mass based on the response to the radar wavefield measured in an abandoned limestone quarry. We applied semi-automatic horizon mapping techniques using manually picked seeds (control points) on selected attributes and automatic extrapolation both on inline and crossline, starting from seed positions. The results were integrated and validated with direct outcrop measures and allowed to image an hydrocarbon reservoir analogue in 3-D up to a depth of over 10m below the topographic surface.Pubblicazioni consigliate
