AUTHORS

Tarald Svanes is discipline leader in subsurface uncertainty treatment at Statoil. Since 1990, he has worked with integrated, three-dimensional reservoir modeling and flow simulation, applying advanced geostatistical techniques. Currently, one of his main focuses is to reduce uncertainty in field prognoses by integrating production data into the reservoir characterization process. Svanes holds an M.S. degree in physics from the Norwegian Technical Institute in Trondheim. At Statoil, he has worked with various aspects of reservoir technology, ranging from research to operational field management, both in the North Sea and internationally.

Allard W. Martinius has an M.Sc. degree from the University of Utrecht and a Ph.D. from Delft University. He joined Statoil in 1996 and spent his first three years at the research center in Trondheim, working on reservoir characterization and modeling of heterolithic tidal res ervoirs. He subsequently joined Sincor in Venezuela as a field development geologist. He returned to Statoil's research center in 2002 to lead a reservoir and uncertainty modeling research group. His main interests are in siliciclastic sedimentology, stratigraphy, reservoir characterization, and geomodeling.

JoAnn Hegre received an M.Sc. degree from Tulane University (U.S.A.). She is currently head of geological research at Total's Geoscience Research Center in London. She has specialized in the field of geomodeling and reservoir characterization for the past seven years. Before taking up this position, she spent three years at Sincor, where she was in charge of geomodeling and volume calculations.

Jean-Pierre Maret joined Total in 1982 and worked as field geologist and team leader at the head office in Paris until 1993. During that period, he spent two years in Abu Dhabi and four years in Buenos Aires. Subsequently, he became exploration manager for Total Myanmar in Yangon, where he spent four years; after which, he was in charge of field evaluation studies and exploration coordinator for southeast Asia. Recently, he worked for two years in Venezuela on the Sincor field, where he was responsible for the geology and geophysics studies and operations. Maret is currently the coordinator for the Americas for Total.

Rune Mjs is lead geologist for the Snorre field, northern North Sea, which he joined in 2002. Prior to that, he was seconded to the Sincor field in Venezuela as senior sedimentologist in the full-field evaluation team. He has been with Statoil since 1991 and has worked as exploration and production geologist on various technical evaluation projects. His main interest is in sedimentology and genetic stratigraphy. From 1997 to 1999, he was Statoil's advisor in sedimentology. Rune has a Cand. Scient. degree from the University of Bergen. After obtaining his degree, he worked for two years as exploration geologist for Norsk Hydro and subsequently, four years as scientist at Rogaland Research Institute. He has published articles on sedimentology, diagenesis, and sequence stratigraphy both for petroleum exploration and production purposes.

Juan Carlos Ustriz Molina, a petroleum engineer from the Universidad Central de Venezuela, obtained his degree in 1994. Since then, he has worked for Mares de Venezuela (MARAVEN) and Petrleos de Venezuela S. A. (PDVSA) in operations and reservoir simulation. In 1998, he started to work for Pennzoil in western Venezuela as a geomodeler and joined Sincrudos de Oriente (SINCOR) as geomodeler in 2000.
