Fracture analysis is crucial because of their abundance in reservoirs and can have a strong effect on fluid flow patterns. Accordingly, Discrete Fracture Network (DFN) model is an efficient alternative approach to modeling fractured reservoirs and it is a special tool that considers fluid flow and transport processes in fractured rock masses through a system of connected fractures. Unlike Dual Porosity Model, where a continuum approach is applied, DFN uses detailed information about fracture and fracture connectivity from data sources like fracture logs and pressure transient data to create distinct fracture sets. In this study, a heavy oil reservoir going through CO2 injection is modeled using DFN approach. It was used as a tool for upscaling geologic information about fractures to the dual-porosity fluid flow simulation. A DFN sector model was created by conditioning to fractures observed in a core scanner and are validated by well test analysis from the field. It has been observed that history matches obtained using a DFN sector model was better than those obtained without upscaled fracture information.
