By combining fracture orientation data with detailed stress and fluid flow measurements, we observe that the orientations of conductive fractures display characteristic patterns attributed to the effect of the present-day triaxial stress state and that the highest transmissivities are associated with fractures having the lowest normal tractions. Our findings indicate that contemporary stress data combined with slip and dilation tendency analysis can be used in predicting the orientations and relative transmissivity values of conductive fractures.
