Statistical analysis has been completed to identify the fractures and breakouts pattern. The results showed that the tectonic stress orientations estimated by the natural fractures (NFs) and the breakout zones (BOs) were different. According to outcrop observations, the NFs reflect the paleo-stress field, while the BOs reflect the current stress field. This study proposed a new method by using fractures with associated conjugate joints, which are obtained from UBI logs, to estimate the paleo-stress orientation.
