Bayesian Algorithm Opens Way to Wellbore Stability

Breakouts provide valuable information with respect to evaluation of maximum horizontal stress magnitude and also<br>verification of the geomechanical model built for a field. Caliper and image logs are routinely used to identify borehole<br>enlargement. However, these methods are limited in their applications in many instances. In addition, good quality image logs<br>are not usually available in old fields. This led to the need for development of a new approach to identify borehole breakouts.
