... incident or lost time. The data recovery was excellent. Data was processed with technologies including Full Waveform Inversion (FWI) for velocity model building and Least Squares Reverse-Time Migration (LSRTM). Dual coil and WAz data were used along with OBN to produce a superior image of the field...

... inversion (FWI), up to 18 Hz, enabled us to derive a detailed velocity model of the MTC, thereby improving the seismic image beneath it. Detailed analysis at a deeper reservoir level showed that event continuity, gather flatness, AVO response and pre-stack P-impedance inversion were all improved after...

... Abstract Full Waveform Inversion (FWI) has become a new tool in recent practice for subsurface velocity model updating. When using FWI, the common scheme was to use data sets which have relatively large offsets up to 8 km or more and frequencies as low as 2.8 Hz considering surface seismic...

... Abstract The emergence of Full Wavefield Inversion (FWI) methods represents a paradigmshift with the potential to revolutionize the way we image and interpretseismic. Advances in algorithms and computing technology are now making FWIpractical, making it possible to construct detailed...
