摘要
Images of subsurface formation walls adjacent well bores are obtained by the borehole imaging systems. The borehole images are processed to characterize the nature of fractures in the formation walls. The fractures are characterized as natural fractures or stress-induced tensile fractures based on the borehole image processing for geomechanical modeling in connection with reservoir characterization, fracture modeling, and stress analysis. A capability is provided to discriminate between the natural fractures and the stress induced tensile fractures and for performance of well activities.
