Abstract: Integrated reservoir modelling (IRM) is a best practice in the Upstream industry applied throughout all life cycles stages of oil and gas projects aiming at characterisation of subsurface reservoirs and optimisation of field development phases. In this respect, carbonate and clastic reservoirs are different in a range of aspects which will be highlighted. During the past 25 years, major steps in technology development have proven the importance of IRM as a key subsurface contributor to Upstream projects. A brief history of IRM through time will be provided using carbonate examples from exploration, development up to recent learnings around unconventional hydrocarbon trapping. More importantly, these industry showcases will be used to introduce present-day challenges around IRM in the Upstream business. Despite the significant progress in modelling technologies, root causes for disappointing results of such studies are limitations in software tools and workflows together with the lack of integration. This often causes poor project delivery. Such pitfalls within existing practices in the Upstream industry will be discussed highlighting that tools only are not able to assure success in subsurface reservoir characterisation projects. Finally, an outlook into the future of hydrocarbon development planning and IRM will be provided. Ultimately, end-to-end integration in Upstream project workflows requires focus on associated business decisions, scaling of models and scenario management supported by content and context based data management as well as capabilities around fast iterative feedback loops. Only the combined improvements around tools, processes and people will maximise value for Upstream project delivery.
Biography: Jürgen is currently Global Learning Advisor Geology at Shell responsible for design and deployment of advanced training programs. In this position, his focus areas are integration and building capabilities around decision based subsurface modelling for muilti-disciplinary teams which he was involved with for the past 25 years in various assignments within Shell Production and Exploration ventures around the world. Jürgen holds a Ph.D. in carbonate sedimentology and has authored and co-authored numerous publications and books. He is known as keynote lecturer from international geoscience conferences and, since 2009, as visiting lecturer at the GeoZentrum of the Universität Erlangen-Nürnberg in Germany. Currently, he is Vice-President of the German Geological Society (DGGV).
