Workshop about Ensemble Kalman filter for updating of reservoir simulation models 
18 - 20 JUNE 2007

Using ensemble Kalman filter for updating of reservoir simulation models has become increasingly popular over the last years. The methodology is very promising to build reservoir simulation models that are conditioned both on prior geostatistical information and production data. In addition, it is suitable for real time updating of reservoir simulation models which may have large implications for the whole reservoir management workflow. The interest in this methodology has resulted in a number of papers, and a lot of activity both within academia and industry. Still there are many challenging problems, and we will use this workshop to give the status of the research that has been performed and give inputs to the researchers and practitioners for their further work. This workshop will follow the lines of the workshop arranged last year at Voss devoted to the same topic.

By bringing together leading technical experts, practitioners, researchers and students for presentations and informal interchange of information we hope to accelerate the development of this area, by giving practitioners ideas of the possibilities of the methodology and the researchers feedback on the most important challenges that have to be addressed.

The workshop is arranged jointly by IRIS and CIPR, University of Bergen, in connection with the Norwegian Research Council (NRC) supported project "Continuous model updating using the ensemble Kalman filter with emphasis on complex reservoirs''. The participants of the project are CIPR, IRIS, University of Oklahomaand University of Tulsa. The workshop provides an excellent opportunity to meet people both from industry and research institutions working in this area.

The workshop is open for anyone interested in the topic, but to provide a forum for informal interchange of ideas, the program committee reserves the right to restrict the number of participants.

Scientific committee: Rolf J. Lorentzen (rjl@iris.no ), Geir Nævdal (gen@iris.no), IRIS and Sigurd Aanonsen (sigurd.aanonsen@cipr.uib.no), CIPR, UoB.

Invited speakers:
Akhil Datta-Gupta, Texas A&M: "Flow Relevant Covariance Localization During History Matching Using EnKF".
Geir Evensen, Norsk Hydro:"Recent developments in the Hydro EnKF implementation and applications".
Dennis McLaughlin, MIT: "Realistic ensemble generation and efficient multiscale estimation for reservoir control problems".
Dean Oliver, University of Oklahoma: "Strategies for Dealing with Strong Nonlinearity in the EnKF".
Henning Omre, Norwegian University of Science & Technology: "Hierarchical ensemble Kalman filter - HEnKF".
Al Reynolds, University of Tulsa: " Evaluation of EnKF for nonlinear/ non-Gaussian problems".

Financial support: This workshop has received financial support from The Norwegian Research Council through the PETROMAKS program.
