Understanding the spatial distribution of natural fractures (orientation and magnitude) is important for drilling and producing from hydrocarbon reservoirs. In unconventional reservoirs (e.g., shale gas, shale oil, tight gas), natural fractures are the only pathways for fluid flow. If there are not enough natural fractures, hydraulic fracturing is required to produce from unconventional reservoirs. For detection and macroscale characterization of fractures, azimuthal seismic anisotropy is one of the most prominent signatures of fractures, which has led to the development of numerous techniques using seismic and log measurements. Microscale characterization of natural fractures, however, requires detailed geologic and core studies. Despite...
