New Insight Brought by the New Broadband 3D Seismic Data from the Witwatersrand Goldfields, South Africa

New Broadband 3D seismic data, acquired for the Witwatersrand goldfields in South Africa, have significantly improved the imaging of the deep (~ 2.5–4.0 km) gold-bearing reefs and faults that offset them. Images appear more continuous and reveal numerous stratigraphic details that were not clear in the old conventional 3D seismic data. The high quality in imaging is a result of a combination of innovative solutions in the field acquisition, processing and interpretation. 3D Volumetric attributes and horizonbased edge detection attributes, in particular, have played an integral part in improving the quality and efficiency of fault mapping in the new broadband 3D seismic data.
