TGS has launched a comprehensive 3D PSDM Multi-Parameter Full Waveform Inversion (FWI) reprocessing project covering approximately 514 square kilometers over Petronas’ 2025 Megah discovery in Block SB-3K, offshore Sabah, Malaysia. Processing for the initiative officially began in July 2026, with final deliverables scheduled for completion in April 2027.
To deliver a substantially modernised dataset, the project will revitalize the legacy Geostreamer Sabah multi-client 3D Phase 2 data by applying advanced Elastic Multi-Parameter FWI and cutting-edge depth imaging technologies. This sophisticated approach aims to significantly reduce subsurface uncertainty and generate a highly accurate representation of the region's complex geology and structural architecture.
