Adding value to old seismic data through re-processing

Gold Fields has an extensive archive of 2D seismic lines acquired in the Witwatersrand Basin during the 1980’s, as<br>well as more recent 3D seismic surveys at the Oryx (1992), Driefontein (1995) and Leeudoorn (Kloof 7 shaft, 1994)<br>mines. Recent projects at Oryx and Kloof needed updated structural interpretations of borehole and seismic data.<br>At Oryx, a new 2D seismic acquisition was considered to tie new boreholes.
