摘要：A geophysical target-oriented approach is proposed to derive seismic sensitivityto 4D positioning mismatches, which focuses on the impact on the reflective responsefrom the reservoir. The sensitivity indicators provide information about the seismic

impact, in terms of reservoir imaging, of a surface positioning mismatch. Someembodiments capitalize on the use of legacy data, enabling a fasttrack analysis to becarried out on the velocity model to extract trends and mapping of lateral geologicalvariability.
