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 which can then be compared to the original image logs to determine the accuracy of the results and if needed repeat the operation to obtain more accurate results.

1-45. (canceled)
A non-transitory program storage device, readable by a processor and comprising instructions stored thereon to cause one or more processors to:
- receive one or more parameters relating to an in-situ stress field in a formation;
- receive one or more input parameters relating to the wellbore;
- and
- generate one or more synthetic image logs for the wellbore,
- wherein the one or more synthetic image logs are generated based on the one or more parameters relating to the in-situ stress field and the one or more input parameters.
A method for generating one or more synthetic image logs for a wellbore in a formation, the method comprising:
- receiving one or more parameters relating to an in-situ stress field in a formation;
- receiving one or more input parameters relating to the wellbore;
- and
- generating one or more synthetic image logs for the wellbore,
- wherein the one or more synthetic image logs are generated based on the one or more parameters relating to the in-situ stress field and the one or more input parameters.
A system, comprising:
- a memory;
- a display device;
- and
- a processor operatively coupled to the memory and the display device and adapted to execute program code stored in the memory to:
- receive one or more parameters relating to an in-situ stress field in a formation;
- receive one or more input parameters relating to the wellbore;
- and
- generate one or more synthetic image logs for the wellbore,
- wherein the one or more synthetic image logs are generated based on the one or more parameters relating to the in-situ stress field and the one or more input parameters.
