    Abstract: A geophysical target-oriented approach is proposed to derive seismic sensitivity to 4D positioning mismatches, which focuses on the impact on the reflective response from the reservoir. The sensitivity indicators provide information about the seismic impact, in terms of reservoir imaging, of a surface positioning mismatch. Some embodiments capitalize on the use of legacy data, enabling a fast-track analysis to be carried out on the velocity model to extract trends and mapping of lateral geological variability.

    Abstract: Methods and systems for target oriented 4D binning of seismic data are presented. A target depth horizon is selected in the vicinity of where 4D changes are expected. Respectively for each data vintage, relationships between the seismic traces and reflection bins, associated with the depth surface, are established and the seismic traces are divided into common reflection angle subsets. The best matching traces from both vintages are selected for each reflection bin and output for further processing.
