Seismic characterization of Volcanogenic massive sulfides – the Semblana orebody, Portugal
MetadataShow full item record
The exploration at Neves Corvo was further progressed through specialised elastic property measurements and PRA processing. Unambiguous imaging of the known VMS deposit was achieved through pre-stack imaging, followed by the calibration of seismic data with sonic and pseudo logs, which was an integral part of the volumetric interpretation. Quantitative interpretation of the Semblana deposit’s was performed with acoustic and elastic impedance inversion and AVO analysis, which demonstrated the unique nature of massive sulfide response.
