Abstract
Systems and methods for predicting an accurate in-situ stress field in a wellbore in a formation are disclosed. The in-situ stress field is calculated using an optimizing process that takes into account parameters relating to induced tensile fracture that are derived from wellbore image logs and other input data relating to the wellbore. Once values for the in-situ stress field are predicted, those values can be used to generate synthetic image logs and fracturing data which can then be compared to the original image logs and fracturing data to determine the accuracy of the results and if needed repeat the operation to obtain more accurate results.
