Midsummer night in Bergen

01.07.2014

For the 9th time IRIS arranged the EnKF workshop together with researchers at Uni Research, CIPR and NERSC June 23-25 at Solstrand Hotel.

It has become a tradition; that world-leading experts within both the theoretical and practical sides of ensemble-based methods meet for three days in the Bergen area every summer.

The aim of the workshop is to bring together technical experts, practitioners, researchers and students for presentations and informal discussions, to share research results and suggest important challenges yet to be addressed.  As intended, the workshop attracts people from atmospheric, oceanographic, hydrologic, and petroleum reservoir communities.

The program contained a great variety of talks within these areas; all the way from the very theoretical aspects to applications such as computer assisted history matching and updating of sedimentary facies boundaries for improved uncertainty quantification in reservoir applications, climate prediction, assimilation of crowdsourcing data, CO2 data assimilation, and wave predictions on the coast of the Netherlands.

This year we were proud to have invited speakers from several well-known universities in Europe and in the US as well as from the oil industry. We also had, for the first time, speakers from two top ranked universities in China, showing the increasing influence of the workshop. Professor Sebastian Reich (University of Potsdam) presented a unified view of the ensemble Kalman filter and the particle filter that give great insight to further development of the methodology. Professor Al Reynolds (University of Tulsa) showed many important aspects of ensemble-based methods for reservoir characterization. The talks from Bob Shuttleworth (ExxonMobil) and Torbjørn Ek and Remus Hanea (Statoil) showed the growing impact of the ensemble based methods in the oil industry.
 
Ensemble based methods are gaining more and more popularity as an estimation and data assimilation tool in many communities, and we see that it is used by the industry. There are, however, still important aspects that need more research and development in the coming years, for example, characterization of complex geological features, regularization and localization to reduce sampling error, modeling and estimation of model errors and integrated workflow with multiple physical processes and data sources.
