The course starts on characterising reservoirs in terms of structure, sedimentology and related petrophysical properties and develops these into static reservoir models. Geostatistics and data integration across the key disciplines will set the baseline. Constructing a reservoir model includes the difficult task to integrate data from very different sources like seismic, well, core and wireline information as well as sedimentological concepts and facies interpretations. It will be shown how modern reservoir modelling practice handles such different viewpoints from geoscience and engineering. This training will teach state-of-the-art concepts, practical fundamentals and common pitfalls when using applications in integrated computer-based modelling. It aims to cover deterministic and stochastic techniques in reservoir modelling and shows how to apply these for populating facies, and properties like porosity, permeability or saturation. The workshop character will be emphasized by showing best practices for constructing useful static geomodels in Petrel software, which are ready to be initialised as simulation models.
