Full Waveform Inversion plays a key role in refining velocity models. By using the full range of seismic data, including both amplitude and phase, FWI helps improve how we image the subsurface. The method is particularly effective in areas with complex geology, where traditional approaches may fall short. FWI supports more accurate seismic migration and better geological interpretation, giving exploration teams the detail they need to reduce uncertainty and make informed decisions.
Dynamic Matching FWI (DM FWI)
Our Dynamic Matching FWI (DM FWI) workflow is a versatile solution with proven record on sparse and shallow water OBN, towed streamer and land seismic, in diverse geological settings.
The increased physics in TGS' Elastic Dynamic Matching FWI (E-DMFWI) produces detailed velocity models with greatly improved resolution in challenging areas compared to acoustic algorithms.
A simultaneous data-driven inversion that delivers superior velocity model and angle-dependent reflectivity directly from raw seismic data, for faster, more accurate and comprehensive earth models.
Our 4D inversion toolkit, formulated in the framework of TGS' DM FWI workflow, offers a cost-effective solution while producing coherent and detailed time-lapse velocity model responses.
