4D seismic close-the-loop impacts business decisions

Time-lapse seismic “4D” close-the-loop (CtL) technology can play a significant role in creating robust static and dynamic models for deepwater reservoirs, as demonstrated by a case study in Equatorial Guinea, West Africa. Initial static and dynamic models for the field were built using well data and seismic attribute volumes, from prestack 3D and 4D simultaneous angle versus offset (AVO) inversions, in conjunction with rock-physics analysis.
