Original Abstract Submitted
Systems and methods for time preserving full waveform inversion are disclosed. The methods may include acquiring, using a seismic acquisition system, a seismic dataset and, using a seismic processor, obtaining, from the seismic dataset, an event in two-way traveltime (TWT) and a velocity model in TWT, and converting the velocity model in TWT into a velocity model in depth. The methods further include producing a final velocity model in depth, where the final velocity model is produced using a full waveform inversion (FWI), the velocity model in depth, and a TWT-preserving method preserves the event in TWT at each iteration of the FWI; and forming a seismic image in depth using the final velocity model in depth and the seismic dataset. The methods further include identifying, using a seismic interpretation workstation and based on the seismic image in depth, a drilling target; and planning a borehole path to the drilling target.
