Technical Abstract

From full waveform inversion to Kirchhoff least-squares migration – correcting the effects of mass-transport complexes for better reservoir imaging

Back to Technical Content
Complex overburden geology often creates difficulties in imaging reservoirs situated below. We used a field dataset from the GOM to demonstrate the benefits of combining FWI and LSM. We were able to generate a high-resolution velocity model through FWI, then use LSM to further improve the reservoir amplitude fidelity by compensating for the overburden and acquisition illumination effects through a round-trip modelling/migration process
