Integrated Reservoir Modelling of the Norne Field.: Volume Visualization/Seismic Attribute,Structural and Property Modeling.

ABSTRACT The purpose of this thesis project work is to build reservoir models (structural, facies and Petrophysical property models) of the different reservoir surfaces using integrated data sets (seismic, wells, fault sticks, eclipse models, horizon surfaces) of the Norne field which is located in...
