Paper Summary
Extracting the most reliable, high quality elastic and reservoir properties from seismic in an effective manner has always been the quest for every geoscientist trying to build a reservoir model or to estimate the petroleum resources. This presentation will focus on the reservoir characterization of a recently acquired and processed multi-azimuth multisensor survey in the prolific South Viking Graben, offshore Norway. This area has delivered a number of significant successes in multiple plays over the past decade. We will focus our analysis on the quantitative interpretation of the various stratigraphic intervals ranging from the Tertiary to the Permian reservoir levels using this dataset integrated with the many wells present in and around the area of interest. From the well data, a company multi-client interactive regional rock physics modelling product has been used, enabling a rapid assessment of the elastic properties variation as well as the pre-stack seismic responses with changes of reservoir condition. This case study will highlight how this new dataset integrated with regional well information can overcome some of the exploration and nearfield exploration challenges. Even though the project work is still on-going, very promising results have been achieved for the evaluation of reservoirs and trapping styles of existing fields and discoveries as well as for the mapping of additional opportunities which would be of interest for any future near-field exploration activity.
