Improving the Seismic Image Quality Within the Preneogene Basement in the Limits of the Producing Oilfield

The oilfield exploitation discovered the zones of significantly differing well performances. The revealed discrepancies were not depended on the structural factor. The pay zone is represented by fractured Paleozoic shists of complicated and heterogeneous structure. Based on the different interpretations studies several fault systems were defined. However existing faults interpretations are ambiguous.

The full azimuth angle domain migration ES360 was applied for the 2015 3D seismic survey data in order to update the existing tectonic model and define the criteria for the further development drilling.

The successful application of the technique caused by the proper survey parameters selection designed for further application of the advanced processing approaches.
