Abstract

The quest for any geoscientist trying to build an accurate reservoir model, or to estimate petroleum resources, has always been to extract reliable, high-quality reservoir properties from seismic data in an efficient manner. This article looks at the reservoir characterization of a recently acquired and processed multi-azimuth multisensor survey in the prolific South Viking Graben, offshore Norway, an area that has delivered numerous significant successes in multiple plays over the past decade. We focus our analysis on the quantitative interpretation of the various stratigraphic intervals ranging from the Tertiary to the Permian reservoir levels by integrating the seismic data with a significant number of wells within and around the area of interest. A proprietary, interactive, regional rock physics modelling tool was used to analyse the available well log information and rapidly assess the expected elastic properties variation and the prestack seismic responses for a range of changes in local reservoir conditions. The case study presented here highlights how newly acquired broadband seismic data, integrated with regional well information, successfully addresses some known regional and near-field exploration challenges. The project is continuing, however, very promising results have already been achieved for the evaluation of reservoir and trapping styles for existing fields and discoveries and also regarding the mapping of new opportunities for future near-field exploration activity.
