We use analogue outcrops to predict orientations of the background fracture network in the subsurface. The novelty of our research is that we group different sets of fractures and stylolites into associations, based on the orientation of the stress field in which they formed. We apply this methodology to the Geneva Basin. Regional observations enable us to predict fracture orientations in the subsurface. 45 % of the fractures observed on image logs of two wells fit the prediction.
