Abstract
- In this work, we apply full waveform inversion (FWI) for CO2 quantification at the Sleipner field. A feasibility study is first carried out on synthetic data to evaluate the capability of FWI to resolve thin CO2 layers. The results show that FWI can improve the resolution of the velocity model at Sleipner and help in better characterizing the CO2 bearing layers velocities and thicknesses. The method is then applied to the 2008 vintage. The inversion results provide clear indications about the geometry and the lateral extent of the CO2 plume. In addition, strong coherency is observed when compared to the migrated image. [ABSTRACT FROM AUTHOR]
