The customer demand was about the fracture gradients along the well-bore trajectories and about the fracture paths. To satisfy the customer demand an integrated study was performed using field data and wellbores evidences. On the base of available information a numerical model has been used that allows taking into account the complex geometry of the faults. The different FSS have been applied to three well-bores and the obtained break-outs have been compared to the observed ones. Two example of FSS, the worst and the best one, are illustrated and compared.
