7th International EnKF Workshop
June 18-20, 2012
Solstrand Hotel & Bad, Os (Bergen)

Welcome to the 7th International EnKF Workshop arranged jointly by IRIS, NERSC and Uni CIPR.

The ensemble Kalman filter (EnKF) and its many variants have been proven effective for data assimilation in large models, including those in atmospheric, oceanic, hydrologic, and petroleum reservoir systems. By bringing together technical experts, practitioners, researchers and students for presentations and informal interchange of information, we aim to share research results and suggest important challenges that have yet to be addressed. Read more here.

The 7th International EnKF workshop is arranged by IRIS in collaboration with the Nansen Center (NERSC) and the Uni Centre for Integrated Petroleum Research (CIPR).  

Invited speakers:
Dennis McLaughlin, (Massachusetts Institute of Technology): "Reduced-order modeling for ensemble real-time control"
Henning Omre, (NTNU): "Uncertainty Quantification in the Ensemble Kalman Filter"
Marc Bocquet, (CEREA, joint laboratory Ecole des Ponts ParisTech and EdF R&D, Univeristé Paris-Est and INRIA): "Combining inflation-free and iterative ensemble Kalman filters for strongly nonlinear systems"
Hans Wackernagel, (MINES ParisTech): "Change of support in geostatistics and data assimilation"
Sigurd Aanonsen, Statoil: "Use of ensemble Kalman filter and ensemble smoother in an operational environment. Application to a North Sea oil field"

The workshop provides an excellent venue for meeting people working on the EnKF from both industry and research institutions, as well as for sharing experiences about the use of EnKF on practical problems. The program will be arranged to allow time for informal discussions both during the sessions and during the cultural event held on the second day. For that reason, the workshop will be held in a location with great opportunities for enjoying the outdoors in Norway.  It is open for anyone interested in the EnKF but to provide an atmosphere conducive to the informal interchange of ideas, the program committee reserves the right to restrict the number of participants.

Call for abstract: The deadline was March 29, 2012.
