The Role of 3D Seismic Data Reprocessing in Order to Increase the Reliability of Geological Interpretation

The problem of reprocessing of seismic data arise whenever the quality of current processing is insufficient for reliable structure interpretation, attribute and AVO analysis and further geological modeling. The paper presents the case story of reprocessing made to overcome a series of drawbacks of original processing results. It is shown how impedance data derived as a result of inversion of seismic 3D volume helps to control the quality of processing and reveal the details of geological structure of the reservoir.
