The main purpose for building a subsurface model is not only for better understanding of the field subsurface but also to define and optimize the field development plan. Depending on the field, the available data, and the application that is used, different companies may have different workflows for building the subsurface model. In most cases, the main input data for building a 3D geological model are wells data and seismic data, which from both data an interpretation and/or extra calculation need to be done.In this study, two different 3D structural models of the studied field were built based on the uncertainty of the interpreted seismic faults; hence two fault models and geological models were created. These geological models were taken for flow simulation analysis where the impact of flow across some of the minor faults in the field productivity was investigated.An integrated static and dynamic reservoir modeling workflow is presented using JewelSuite Subsurface Modeling software to quickly build multiple 3D structure scenarios, address the effect of different stratigraphic zonation, different fault connectivity, and/or different fluid compartmentalization, carry on fluids volumes quantification and study their dynamics in the porous media.
