Abstract

Summary

This abstract covers the application of 4D full waveform inversion (FWI) on an Ultra High Density Ocean Bottom Node dataset. The node count was over 25,000 for the project, which is an incredibly high number. The work explores different methods of 4D FWI and compares their results between a test swath and full production showing how limited data in tests can lead to sub-optimal results. The paper will be able to compare the 4D FWI results to standard processed and imaged data.
