Building a reliable static model of a reservoir requires the information provided by geologists, geophysics and petroleum engineers. This executive course concentrates on presenting the case studies, practical tools and guidelines of Geostatistics for the process of static reservoir modeling. The best practices, pros and cons will be discussed through each methodology. The approaches to dealing with trend will also be argued for further analysis of facies and petrophysical data (e.g. porosity, permeability and etc.,).
