Various implementations directed to determining a fracture type using stress analysis are provided. In one implementation, a method may include receiving seismic data acquired in a seismic survey of a region of interest. The method may also include performing a kinematic analysis on the seismic data. The method may further include generating fracture planes from the seismic data based on the kinematic analysis. The method may additionally include generating a mechanical earth model based on the seismic data. The method may further include performing a critical stress analysis on the fracture planes based on the mechanical earth model. The method may also include determining a fracture type of respective fractures in the fracture planes based on the critical stress analysis.
