AbstractGiven the importance of fractured reservoirs in the world, and the ever-increasing availability of 3D seismic data, this paper reviews existing fracture modeling approaches that use 3D seismic data. Two major approaches appear to provide efficient ways to use directly and effectively 3D seismic data. The first approach uses mostly post-stack data in an integrated computational framework where 3D seismic attributes are used along with other geologic and geomechanical information to provide reliable 3D fracture models. The second approach relies on the use of pre-stack seismic data along with other geologic and production information to provide an accurate description of the fracture density and orientation. Although these technologies are well proven and have been tested in many basins, they remain underutilized by most oil and gas companies, with the exception of a few companies that have been using them extensively to drill very successful wells.
