Characterization and Prediction of Seal Lithological Variability from Log and Seismic Data

Author presents an approach for data integration at different scales and for characterisation and prediction of seal properties variations which define seal quality. Presented is an original methodology for seal mud-rich facies recognition from conventional logs and their distribution parameters assignment to the seismic attributes. Sensitivity analysis of the recognition and characterization methods is performed, which allows to quantify seal capacity and its determination uncertainty at seismic scale.
