A Practical Approach to the Computation of Multivalued Geometrical Spreading Factors
Authors S. Buske and U. KästnerThis paper presents an application of a recently developed method for computing the ray propagator from traveltimes (Gajewski (1998)).

History Matching and Reservoir Model Updating by Integrating Additional Dynamic Data
Authors M. Le Ravalec, L. Y. Hu, B. Noetinger and G. BlancThis paper presents a methodology to constrain reservoir models to geological information and well and historical production data, but also to update a given reservoir model to integrate the newly obtained dynamic data without running again the reservoir characterization study from the very beginning. A synthetic example is reported to evidence the efficiency of the approach.

Negative Geoskin - the Key to Understanding the Near Well Bore Influence of Some Geological Elements in Well Testing
Authors P. Corbett, A. Sagawa, S. Zheng and G. StewartIn reservoir description, well testing is a useful tool for describing the region of the reservoir away from the well bore.

Towards and Improved Fault Representation in Two-Phase Reservoir Simulation
By T. ManzocchiThe single phase petrophysical properties of faults (essentially fault zone permeability and thickness) can be included in reservoir flow simulation models using dimensionless transmissibility multipliers.

Multi-Scale Assessment of Gas/Oil Displacements in a Thinly-Layered (Tidal) Reservoir System
Authors P. Ringrose, A. Sharif, P. Kristian Munkerud and A. NæssThis paper presents a sensitivity study of effective properties, fluid displacements and recovery behaviour of heterogeneous tidal deposits in a gas condensate field, offshore mid-Norway.

Occurrence and Quantification of Tectonically Induced Fracture Porosity
By K. J. WeberOpen fractures are in the limelight because of the growing development of tight gas fields with horizontal wells, but also in connection with renewed interest in the many giant fractured fields around the world.

Enhancement of a Flat Spot from Seismic Data Using Multi-Attribute Analysis
Authors R. J. Arts and Y. P. AmpilovIn this case study multi-attribute analysis has been applied to seismic data to support the interpretation of a flat spot caused by an oil-water contact in a carbonate reservoir.

Three-Dimensional Visualisation of a Structurally and Stratigraphically Complex Reservoir
Authors K. S. Hoffman and R. M. SlattAnalysis of over 1100 wells has provided the basis for identifying and mapping a complex structurally compartmentalized Terry sandstone reservoir in a 70-section area of the Denver Basin, Colorado.

Prediction from 3D Seismic Data of Productive Zones Within the Jurassic Bazhenov and Underlying Sections in the Salym Area of West Siberia
Authors G. N. Gogonenkov, A. V. Grinshpun and S. I. BachinIn the 70s, oil inflow rates in some exploratory wells that penetrated Upper Jurassic shaly-bituminous section of the Bazhenov Suite in the central part of West Siberia were very significant (several hundreds of tons per day).
